From 11945a73c631bedbcf8daaba531964c3fc2d6333 Mon Sep 17 00:00:00 2001 From: "justdave%syndicomm.com" <> Date: Thu, 5 Feb 2004 12:49:08 +0000 Subject: - Remove html, txt, and pdf directories from CVS - makedocs.pl now creates said directories when building the docs The idea here is that it's useless to have compiled stuff in CVS. The website will now auto-build the docs upon changes to the xml directory. --- docs/html/Bugzilla-Guide.html | 13262 --------------------------- docs/html/about.html | 174 - docs/html/administration.html | 206 -

Chapter 2. Installing Bugzilla

2.1. Installation

If you just want to use Bugzilla, - you do not need to install it. None of this chapter is relevant to - you. Ask your Bugzilla administrator - for the URL to access it over the web. -

The Bugzilla server software is usually installed on Linux or - Solaris. - If you are installing on another OS, check Section 2.4 - before you start your installation to see if there are any special - instructions. -

As an alternative to following these instructions, you may wish to - try Arne Schirmacher's unofficial and unsupported - Bugzilla - Installer, which installs Bugzilla and all its prerequisites - on Linux or Solaris systems. -

This guide assumes that you have administrative access to the - Bugzilla machine. It not possible to - install and run Bugzilla itself without administrative access except - in the very unlikely event that every single prerequisite is - already installed. -

The installation process may make your machine insecure for - short periods of time. Make sure there is a firewall between you - and the Internet. -

You are strongly recommended to make a backup of your system - before installing Bugzilla (and at regular intervals thereafter :-). -

In outline, the installation proceeds as follows: -

  1. Install Perl - (5.6.0 or above) -

  2. Install MySQL - (3.23.41 or above) -

  3. Install a Webserver -

  4. Install Bugzilla -

  5. Install Perl modules -

  6. Configure all of the above. -

2.1.1. Perl

Installed Version Test: perl -v

Any machine that doesn't have Perl on it is a sad machine indeed. - If you don't have it and your OS doesn't provide official packages, - visit http://www.perl.com. - Although Bugzilla runs with Perl 5.6.0, - it's a good idea to be using the latest stable version. - As of this writing, that is Perl 5.8.2.

2.1.2. MySQL

Installed Version Test: mysql -V

If you don't have it and your OS doesn't provide official packages, - visit http://www.mysql.com. You need MySQL version - 3.23.41 or higher. -

Many of the binary - versions of MySQL store their data files in - /var. - On some Unix systems, this is part of a smaller root partition, - and may not have room for your bug database. To change the data - directory, you have to build MySQL from source yourself, and - set it as an option to configure.

If you install from something other than a packaging/installation - system (such as .rpm, .dep, .exe, or .msi) make sure the MySQL server - is started when the machine boots. -

2.1.3. Web Server

Installed Version Test: view the default welcome page at - http://<your-machine>/

You have freedom of choice here, pretty much any web server that - is capable of running CGI - scripts will work. - However, we strongly recommend using the Apache web server - (either 1.3.x or 2.x), and - the installation instructions usually assume you are - using it. If you have got Bugzilla working using another webserver, - please share your experiences with us by filing a bug in Bugzilla Documentation. -

If you don't have Apache and your OS doesn't provide official packages, - visit http://httpd.apache.org/. -

2.1.4. Bugzilla

Download a Bugzilla tarball (or check it out from CVS) and place - it in a suitable directory, writable by the default web server user - (probably "nobody"). - Good locations are either directly in the main web space for your - web server or perhaps in - /usr/local - with a symbolic link from the web space. -

The default Bugzilla distribution is not designed to be placed - in a cgi-bin directory. This - includes any directory which is configured using the - ScriptAlias directive of Apache. -

Once all the files are in a web accessible directory, make that - directory writable by your webserver's user. This is a temporary step - until you run the - checksetup.pl - script, which locks down your installation.

2.1.5. Perl Modules

Bugzilla's installation process is based - on a script called checksetup.pl. - The first thing it checks is whether you have appropriate - versions of all the required - Perl modules. The aim of this section is to pass this check. - When it passes, - do not run it again, - but proceed to Section 2.2. -

At this point, you need to su to root. You should - remain as root until the end of the install. Then run: - 

bash# ./checksetup.pl

checksetup.pl will print out a list of the - required and optional Perl modules, together with the versions - (if any) installed on your machine. - The list of required modules is reasonably long; however, you - may already have several of them installed. -

There is a meta-module called Bundle::Bugzilla, - which installs all the other - modules with a single command. You should use this if you are running - Perl 5.6.1 or above. -

The preferred way of installing Perl modules is via CPAN on Unix, - or PPM on Windows (see Section 2.4.1.2). These - instructions assume you are using CPAN; if for some reason you need - to install the Perl modules manually, see - Appendix C. - 

bash# perl -MCPAN -e 'install "<modulename>"'

If you using Bundle::Bugzilla, invoke the magic CPAN command on it. - Otherwise, you need to work down the - list of modules that checksetup.pl says are - required, in the order given, invoking the command on each. -

Many people complain that Perl modules will not install for - them. Most times, the error messages complain that they are missing a - file in - "@INC". - Virtually every time, this error is due to permissions being set too - restrictively for you to compile Perl modules or not having the - necessary Perl development libraries installed on your system. - Consult your local UNIX systems administrator for help solving these - permissions issues; if you - are - the local UNIX sysadmin, please consult the newsgroup/mailing list - for further assistance or hire someone to help you out.

Here is a complete list of modules and their minimum versions. - Some modules have special installation notes, which follow. -

Required Perl modules: -

  1. AppConfig (1.52) -

  2. CGI (2.93) -

  3. Data::Dumper (any) -

  4. Date::Format (2.21) -

  5. DBI (1.32) -

  6. DBD::mysql - (2.1010) -

  7. File::Spec (0.82) -

  8. File::Temp (any) -

  9. Template - (2.08) -

  10. Text::Wrap (2001.0131) -

- - Optional Perl modules: -

  1. GD - (1.20) for bug charting -

  2. Chart::Base - (0.99c) for bug charting -

  3. GD::Graph - (any) for bug charting -

  4. GD::Text::Align - (any) for bug charting -

  5. XML::Parser - (any) for the XML interface -

  6. PatchReader - (0.9.1) for pretty HTML view of patches -

  7. MIME::Parser - (any) for the optional email interface -

-

2.1.5.1. DBD::mysql

The installation process will ask you a few questions about the - desired compilation target and your MySQL installation. For most of the - questions the provided default will be adequate, but when asked if your - desired target is the MySQL or mSQL packages, you should - select the MySQL-related ones. Later you will be asked if you wish to - provide backwards compatibility with the older MySQL packages; you - should answer YES to this question. The default is NO.

A host of 'localhost' should be fine. A testing user of 'test', - with a null password, should have sufficient access to run - tests on the 'test' database which MySQL creates upon installation. -

2.1.5.2. Template Toolkit (2.08)

When you install Template Toolkit, you'll get asked various - questions about features to enable. The defaults are fine, except - that it is recommended you use the high speed XS Stash of the Template - Toolkit, in order to achieve best performance. -

2.1.5.3. GD (1.20)

The GD module is only required if you want graphical reports. -

The Perl GD module requires some other libraries that may or - may not be installed on your system, including - libpng - and - libgd. - The full requirements are listed in the Perl GD module README. - If compiling GD fails, it's probably because you're - missing a required library.

The version of the GD module you need is very closely tied - to the libgd version installed on your system. - If you have a version 1.x of libgd the 2.x - versions of the GD module won't work for you. -

2.1.5.4. Chart::Base (0.99c)

The Chart::Base module is only required if you want graphical - reports. - Note that earlier versions that 0.99c used GIFs, which are no longer - supported by the latest versions of GD.

2.1.5.5. GD::Graph (any)

The GD::Graph module is only required if you want graphical - reports. -

2.1.5.6. GD::Text::Align (any)

The GD::Text::Align module is only required if you want graphical - reports. -

2.1.5.7. XML::Parser (any)

The XML::Parser module is only required if you want to import - XML bugs using the importxml.pl - script. This is required to use Bugzilla's "move bugs" feature; - you may also want to use it for migrating from another bug database. - XML::Parser requires that the - expat library is already installed on your machine. -

2.1.5.8. MIME::Parser (any)

The MIME::Parser module is only required if you want to use the - email interface - located in the contrib directory. -

2.1.5.9. PatchReader (0.9.1)

The PatchReader module is only required if you want to use - Patch Viewer, a - Bugzilla feature to show code patches in your web browser in a more - readable form. -

2.2. Configuration

Poorly-configured MySQL and Bugzilla installations have - given attackers full access to systems in the past. Please take the - security parts of these guidelines seriously, even for Bugzilla - machines hidden away behind your firewall.

2.2.1. localconfig

Once you run checksetup.pl with all the correct - modules installed, it displays a message about, and write out a - file called, - localconfig. This file contains the default - settings for a number of Bugzilla parameters. -

Load this file in your editor. The only value you - need to change is $db_pass, the password for - the user you will create for your database. - Pick a strong password (for simplicity, it should not contain - single quote characters) and put it here. -

The other options in the localconfig file - are documented by their accompanying comments. If you have a slightly - non-standard MySQL setup, you may wish to change one or more of - the other "$db_*" parameters. -

You may also wish to change the names of - the priorities, severities, operating systems and platforms for your - installation. However, you can always change these after installation - has finished; if you then re-run - checksetup.pl, the changes will get picked up. -

2.2.2. MySQL

2.2.2.1. Security

MySQL ships as insecure by default. - It allows anybody to on the local machine full administrative - capabilities without requiring a password; the special - MySQL root account (note: this is not the same as - the system root) also has no password. - Also, many installations default to running - mysqld as the system root. -

  1. To disable the anonymous user account - and set a password for the root user, execute the following. The - root user password should be different to the bugs user password - you set in - localconfig in the previous section, - and also different to - the password for the system root account on your machine. - 

      bash$ mysql mysql
-  mysql> DELETE FROM user WHERE user = '';
-  mysql> UPDATE user SET password = password('new_password') WHERE user = 'root';
-  mysql> FLUSH PRIVILEGES;

    From this point forward, to run the - mysql command-line client, - you will need to type - mysql -u root -p and enter - new_password when prompted. -

  2. If you run MySQL on the same machine as your web server, you - should disable remote access to MySQL by adding - the following to your /etc/my.conf: - 

      [myslqd]
-  # Prevent network access to MySQL.
-  skip-networking

  3. Consult the documentation that came with your system for - information on making mysqld run as an - unprivileged user. -

  4. For added security, you could also run MySQL, or even all - of Bugzilla - in a chroot jail; however, instructions for doing that are beyond - the scope of this document. -

2.2.2.2. Allow large attachments

You need to configure MySQL to accept large packets, if you - want to have attachments larger than 64K. Add the text - below to your - /etc/my.conf. - There is also a parameter in Bugzilla - for setting the maximum allowable attachment size, (default 1MB). - Bugzilla will only accept attachments up to the lower of these two - sizes. - 

  [mysqld]
-  # Allow packets up to 1M
-  set-variable = max_allowed_packet=1M

2.2.2.3. Add a user to MySQL

You need to add a new MySQL user for - Bugzilla to use. (It's not safe to have Bugzilla use the MySQL root - account.) The following instructions assume the defaults in - localconfig; - if you changed those, you need to modify the - SQL command appropriately. You will need the - $db_pass password you set in - localconfig in - Section 2.2.1. -

We use an SQL GRANT command to create a - "bugs" - user. This also restricts the - "bugs" - user to operations within a database called - "bugs", and only allows the account to connect from - "localhost". - Modify it to reflect your setup if you will be connecting from - another machine or as a different user.

Run the mysql command-line client and - enter:

  mysql> GRANT SELECT,INSERT,UPDATE,DELETE,INDEX,ALTER,CREATE,
-         DROP,REFERENCES ON bugs.* TO bugs@localhost
-         IDENTIFIED BY '$db_pass';
-  mysql> FLUSH PRIVILEGES

If you are using MySQL 4, you need to add - the LOCK TABLES and - CREATE TEMPORARY TABLES permissions - to the list. -

2.2.3. checksetup.pl

Next, rerun checksetup.pl. It reconfirms - that all the modules are present, and notices the altered - localconfig file, which it assumes you have edited to your - satisfaction. It compiles the UI templates, - connects to the database using the 'bugs' - user you created and the password you defined, and creates the - 'bugs' database and the tables therein. -

After that, it asks for details of an administrator account. Bugzilla - can have multiple administrators - you can create more later - but - it needs one to start off with. - Enter the email address of an administrator, his or her full name, - and a suitable Bugzilla password. -

checksetup.pl will then finish. You may rerun - checksetup.pl at any time if you wish. -

2.2.4. Web server

Configure your web server according to the instructions in the - appropriate section. The Bugzilla Team recommends Apache. -

2.2.4.1. Apache httpd

Load httpd.conf in your editor.

Uncomment (or add) the following line. - This configures Apache to run .cgi files outside the - cgi-bin directory. - 

  AddHandler cgi-script .cgi

Apache uses <Directory> - directives to permit fine-grained permission setting. - Add the following two lines to a - <Directory> directive that - applies either to the Bugzilla directory or one of its parents - (e.g. the <Directory /var/www/html> - directive). - This allows Bugzilla's .htaccess files to - override global permissions, and allows .cgi files to run in the - Bugzilla directory. - 

  Options +ExecCGI +FollowSymLinks
-  AllowOverride Limit

Add index.cgi to the end - of the DirectoryIndex - line.

checksetup.pl can set tighter permissions - on Bugzilla's files and directories if it knows what user the - webserver runs as. Look for the User - line in httpd.conf, and place that value in - the $webservergroup variable in - localconfig. Then rerun - checksetup.pl. -

2.2.4.2. Microsoft Internet Information Services

If you need, or for some reason even want, to use Microsoft's - Internet Information Services or - Personal Web Server you should be able - to. You will need to configure them to know how to run CGI scripts. - This is described in Microsoft Knowledge Base article - Q245225 - for Internet Information Services and - Q231998 - for Personal Web Server. -

Also, and this can't be stressed enough, make sure that files such as - localconfig and your data - directory are secured as described in Section 2.2.4.4. -

2.2.4.3. AOL Server

Ben FrantzDale reported success using AOL Server with Bugzilla. He - reported his experience and what appears below is based on that. -

AOL Server will have to be configured to run - CGI scripts, please consult - the documentation that came with your server for more information on - how to do this. -

Because AOL Server doesn't support .htaccess - files, you'll have to create a TCL - script. You should create an aolserver/modules/tcl/filter.tcl - file (the filename shouldn't matter) with the following contents (change - /bugzilla/ to the web-based path to - your Bugzilla installation): - 


  ns_register_filter preauth GET /bugzilla/localconfig filter_deny
-  ns_register_filter preauth GET /bugzilla/localconfig~ filter_deny
-  ns_register_filter preauth GET /bugzilla/\#localconfig\# filter_deny
-  ns_register_filter preauth GET /bugzilla/*.pl filter_deny
-  ns_register_filter preauth GET /bugzilla/syncshadowdb filter_deny
-  ns_register_filter preauth GET /bugzilla/runtests.sh filter_deny
-  ns_register_filter preauth GET /bugzilla/data/* filter_deny
-  ns_register_filter preauth GET /bugzilla/template/* filter_deny
-
-  proc filter_deny { why } {
-      ns_log Notice "filter_deny"
-      return "filter_return"
-  }
-

This probably doesn't account for all possible editor backup - files so you may wish to add some additional variations of - localconfig. For more information, see - bug 186383 or Bugtraq ID 6501. -

If you are using webdot from research.att.com (the default - configuration for the webdotbase paramater), you - will need to allow access to data/webdot/*.dot - for the reasearch.att.com machine. -

If you are using a local installation of GraphViz, you will need to allow - everybody to access *.png, - *.gif, *.jpg, and - *.map in the - data/webdot directory. -

2.2.4.4. Web Server Access Controls

Users of Apache can skip this section because - Bugzilla ships with .htaccess files which - restrict access in the manner required. - Users of other webservers, read on. -

There are several files in the Bugzilla directory - that should not be accessible from the web. You need to configure - your webserver so they they aren't. Not doing this may reveal - sensitive information such as database passwords. -

  • In the main Bugzilla directory, you should:

    • Block: - *.pl, *localconfig*, runtests.sh -

    • But allow: - localconfig.js, localconfig.rdf -

  • In data:

    • Block everything

    • But allow: - duplicates.rdf -

  • In data/webdot:

    • If you use a remote webdot server:

      • Block everything

      • But allow - *.dot - only for the remote webdot server

    • Otherwise, if you use a local GraphViz:

      • Block everything

      • But allow: - *.png, *.gif, *.jpg, *.map -

    • And if you don't use any dot:

      • Block everything

  • In Bugzilla:

    • Block everything

  • In template:

    • Block everything

You should test to make sure that the files mentioned above are - not accessible from the Internet, especially your - localconfig file which contains your database - password. To test, simply point your web browser at the file; for - example, to test mozilla.org's installation, we'd try to access - http://bugzilla.mozilla.org/localconfig. You should - get a 403 Forbidden - error. -

2.2.5. Bugzilla

Your Bugzilla should now be working. Access - http://<your-bugzilla-server>/ - - you should see the Bugzilla - front page. If not, consult the Troubleshooting section, - Section 2.5. -

Log in with the administrator account you defined in the last - checksetup.pl run. You should go through - the parameters on the Edit Parameters page - (see link in the footer) and see if there are any you wish to - change. - They key parameters are documented in Section 3.1; - you should certainly alter - maintainer and urlbase; - you may also want to alter - cookiepath or requirelogin. -

This would also be a good time to revisit the - localconfig file and make sure that the - names of the priorities, severities, platforms and operating systems - are those you wish to use when you start creating bugs. Remember - to rerun checksetup.pl if you change it. -

Bugzilla has several optional features which require extra - configuration. You can read about those in - Section 2.3. -

2.3. Optional Additional Configuration

Bugzilla has a number of optional features. This section describes how - to configure or enable them. -

2.3.1. Bug Graphs

If you have installed the necessary Perl modules you - can start collecting statistics for the nifty Bugzilla - graphs.

bash# crontab -e

This should bring up the crontab file in your editor. - Add a cron entry like this to run - collectstats.pl - daily at 5 after midnight: - 

5 0 * * * cd <your-bugzilla-directory> ; ./collectstats.pl

After two days have passed you'll be able to view bug graphs from - the Reports page.

2.3.2. Dependency Charts

As well as the text-based dependency trees, Bugzilla also - supports a graphical view of dependency relationships, using a - package called 'dot'. - Exactly how this works is controlled by the 'webdotbase' parameter, - which can have one of three values: -

  1. A complete file path to the command 'dot' (part of - GraphViz) - will generate the graphs locally -

  2. A URL prefix pointing to an installation of the webdot package will - generate the graphs remotely -

  3. A blank value will disable dependency graphing. -

-

The easiest way to get this working is to install - GraphViz. If you - do that, you need to - enable - server-side image maps in Apache. - Alternatively, you could set up a webdot server, or use the AT&T - public webdot server. This is the default for the webdotbase param, - but it's often overloaded and slow. Note that AT&T's server - won't work - if Bugzilla is only accessible using HARTS. - Editor's note: What the heck is HARTS? Google doesn't know... - -

2.3.3. The Whining Cron

What good are - bugs if they're not annoying? To help make them more so you - can set up Bugzilla's automatic whining system to complain at engineers - which leave their bugs in the NEW or REOPENED state without triaging them. -

- This can be done by - adding the following command as a daily crontab entry, in the same manner - as explained above for bug graphs. This example runs it at 12.55am. - 

55 0 * * * cd <your-bugzilla-directory> ; ./whineatnews.pl

2.3.4. Patch Viewer

Patch Viewer is the engine behind Bugzilla's graphical display of - code patches. You can integrate this with copies of the - cvs, lxr and - bonsai tools if you have them, by giving - the locations of your installation of these tools in - editparams.cgi. -

Patch Viewer also optionally will use the - cvs, diff and - interdiff - command-line utilities if they exist on the system. - Interdiff can be obtained from - http://cyberelk.net/tim/patchutils/. - If these programs are not in the system path, you can configure - their locations in localconfig. -

2.3.5. LDAP Authentication

LDAP authentication is a module for Bugzilla's plugin - authentication architecture. -

The existing authentication - scheme for Bugzilla uses email addresses as the primary user ID, and a - password to authenticate that user. All places within Bugzilla where - you need to deal with user ID (e.g assigning a bug) use the email - address. The LDAP authentication builds on top of this scheme, rather - than replacing it. The initial log in is done with a username and - password for the LDAP directory. This then fetches the email address - from LDAP and authenticates seamlessly in the standard Bugzilla - authentication scheme using this email address. If an account for this - address already exists in your Bugzilla system, it will log in to that - account. If no account for that email address exists, one is created at - the time of login. (In this case, Bugzilla will attempt to use the - "displayName" or "cn" attribute to determine the user's full name.) - After authentication, all other user-related tasks are still handled by - email address, not LDAP username. You still assign bugs by email - address, query on users by email address, etc. -

Because the Bugzilla account is not created until the first time - a user logs in, a user who has not yet logged is unknown to Bugzilla. - This means they cannot be used as an assignee or QA contact (default or - otherwise), added to any cc list, or any other such operation. One - possible workaround is the bugzilla_ldapsync.rb - script in the - contrib directory. Another possible solution is fixing - bug - 201069. -

Parameters required to use LDAP Authentication:

loginmethod

This parameter should be set to "LDAP" - only if you will be using an LDAP directory - for authentication. If you set this param to "LDAP" but - fail to set up the other parameters listed below you will not be - able to log back in to Bugzilla one you log out. If this happens - to you, you will need to manually edit - data/params and set loginmethod to - "DB". -

LDAPserver

This parameter should be set to the name (and optionally the - port) of your LDAP server. If no port is specified, it assumes - the default LDAP port of 389. -

Ex. "ldap.company.com" - or "ldap.company.com:3268" -

LDAPbinddn [Optional]

Some LDAP servers will not allow an anonymous bind to search - the directory. If this is the case with your configuration you - should set the LDAPbinddn parameter to the user account Bugzilla - should use instead of the anonymous bind. -

Ex. "cn=default,cn=user:password"

LDAPBaseDN

The LDAPBaseDN parameter should be set to the location in - your LDAP tree that you would like to search for email addresses. - Your uids should be unique under the DN specified here. -

Ex. "ou=People,o=Company"

LDAPuidattribute

The LDAPuidattribute parameter should be set to the attribute - which contains the unique UID of your users. The value retrieved - from this attribute will be used when attempting to bind as the - user to confirm their password. -

Ex. "uid"

LDAPmailattribute

The LDAPmailattribute parameter should be the name of the - attribute which contains the email address your users will enter - into the Bugzilla login boxes. -

Ex. "mail"

2.3.6. Prevent users injecting malicious - Javascript

It is possible for a Bugzilla user to take advantage of character - set encoding ambiguities to inject HTML into Bugzilla comments. This - could include malicious scripts. - Due to internationalization concerns, we are unable to - incorporate by default the code changes suggested by - the CERT advisory on this issue. - If your installation is for an English speaking audience only, making the - change below will prevent this problem. -

Simply locate the following line in - Bugzilla/CGI.pm: - 
$self->charset('');
- and change it to: - 
$self->charset('ISO-8859-1');
-

2.3.7. mod_throttle

It is possible for a user, by mistake or on purpose, to access - the database many times in a row which can result in very slow access - speeds for other users. If your Bugzilla installation is experiencing - this problem, you may install the Apache module - mod_throttle - which can limit connections by IP address. You may download this module - at - http://www.snert.com/Software/mod_throttle/. - Follow the instructions to install into your Apache install. - This module only functions with the Apache web - server! - The command you need is - ThrottleClientIP. See the - documentation - for more information.

2.3.8. TCP/IP Ports

A single-box Bugzilla only requires port 80, plus port 25 if - you are using the optional email interface. You should firewall all - other ports and/or disable services listening on them. -

2.3.9. Daemon Accounts

Many daemons, such as Apache's httpd and MySQL's mysqld default to - running as either "root" or "nobody". Running - as "root" introduces obvious security problems, but the - problems introduced by running everything as "nobody" may - not be so obvious. Basically, if you're running every daemon as - "nobody" and one of them gets compromised, they all get - compromised. For this reason it is recommended that you create a user - account for each daemon. -

2.4. OS-Specific Installation Notes

Many aspects of the Bugzilla installation can be affected by the - the operating system you choose to install it on. Sometimes it can be made - easier and others more difficult. This section will attempt to help you - understand both the difficulties of running on specific operating systems - and the utilities available to make it easier. -

If you have anything to add or notes for an operating system not - covered, please file a bug in Bugzilla Documentation. -

2.4.1. Microsoft Windows

Making Bugzilla work on Windows is still a painful processes. - The Bugzilla Team is working to make it easier, but that goal is not - considered a top priority. If you wish to run Bugzilla, we still - recommend doing so on a Unix based system such as GNU/Linux. As of this - writing, all members of the Bugzilla team and all known large installations - run on Unix based systems. -

If after hearing all that, you have enough pain tolerance to attempt - installing Bugzilla on Win32, here are some pointers. - - Because this is a development version of the guide, these instructions - are subject to change without notice. In fact, the Bugzilla Team hopes - to have Bugzilla reasonably close to "out of - the box" compatibility with Windows by the 2.18 release. - -

2.4.1.1. Win32 Perl

Perl for Windows can be obtained from ActiveState. You should be - able to find a compiled binary at http://aspn.activestate.com/ASPN/Downloads/ActivePerl/. -

2.4.1.2. Perl Modules on Win32

Bugzilla on Windows requires the same perl modules found in - Section 2.1.5. The main difference is that - windows uses PPM instead of - CPAN. - 


C:\perl> ppm <module name>
-

The above syntax should work for all modules with the exception - of Template Toolkit. The Template Toolkit website - suggests using the instructions on OpenInteract's website. -

2.4.1.3. Code changes required to run on win32

As Bugzilla still doesn't run "out of the box" on - Windows, code has to be modified. This section lists the required - changes. -

2.4.1.3.1. Changes to checksetup.pl

In checksetup.pl, the line reading:


my $mysql_binaries = `which mysql`;
-

to


my $mysql_binaries = "D:\\mysql\\bin\\mysql";
-

And you'll also need to change:


my $webservergid = getgrnam($my_webservergroup)
-

to


my $webservergid = '8'
-

2.4.1.3.2. Changes to BugMail.pm

To make bug email work on Win32 (until - bug - 84876 lands), the - simplest way is to have the Net::SMTP Perl module installed and - change this:


open(SENDMAIL, "|/usr/lib/sendmail $sendmailparam -t -i") ||
-  die "Can't open sendmail";
-
-print SENDMAIL trim($msg) . "\n";
-close SENDMAIL;
-

to


use Net::SMTP;
-my $smtp_server = 'smtp.mycompany.com';  # change this
-
-# Use die on error, so that the mail will be in the 'unsent mails' and
-# can be sent from the sanity check page.
-my $smtp = Net::SMTP->new($smtp_server) ||
-  die 'Cannot connect to server \'$smtp_server\'';
-
-$smtp->mail('bugzilla-daemon@mycompany.com');  # change this
-$smtp->to($person);
-$smtp->data();
-$smtp->datasend($msg);
-$smtp->dataend();
-$smtp->quit;
-

Don't forget to change the name of your SMTP server and the - domain of the sending email address (after the '@') in the above - lines of code.

2.4.1.4. Serving the web pages

As is the case on Unix based systems, any web server should be - able to handle Bugzilla; however, the Bugzilla Team still recommends - Apache whenever asked. No matter what web server you choose, be sure - to pay attention to the security notes in Section 2.2.4.4. - More information on configuring specific web servers can be found in - Section 2.2.4. -

If using Apache on windows, you can set the ScriptInterpreterSource - directive in your Apache config to avoid having - to modify the first line of every script to contain your path to - perl instead of /usr/bin/perl. -

2.4.2. Mac OS X

Apple did not include the GD library with Mac OS X. Bugzilla - needs this for bug graphs.

You can install it using a program called - Fink, which is similar in nature to the CPAN installer, but installs - common GNU utilities. Fink is available from - http://sourceforge.net/projects/fink/.

Follow the instructions for setting up Fink. Once it's installed, - you'll want to use it to install the gd2 package. -

It will prompt you for a number of dependencies, type 'y' and hit - enter to install all of the dependencies and then watch it work. You will - then be able to use CPAN to - install the GD Perl module. -

To prevent creating conflicts with the software that Apple - installs by default, Fink creates its own directory tree at - /sw where it installs most of - the software that it installs. This means your libraries and headers be - at /sw/lib and - /sw/include instead of - /usr/lib and - /usr/local/include. When the - Perl module config script asks where your libgd is, be sure to tell it - /sw/lib. -

Also available via Fink is expat. After using fink to - install the expat package you will be able to install - XML::Parser using CPAN. There is one caveat. Unlike recent versions of - the GD module, XML::Parser doesn't prompt for the location of the - required libraries. When using CPAN, you will need to use the following - command sequence: - 


# perl -MCPAN -e'look XML::Parser'        
-# perl Makefile.PL EXPATLIBPATH=/sw/lib EXPATINCPATH=/sw/include
-# make; make test; make install           
-# exit                                    
-
The look command will download the module and spawn a - new shell with the extracted files as the current working directory. - The exit command will return you to your original shell. -
You should watch the output from these make commands, - especially "make test" as errors may prevent XML::Parser - from functioning correctly with Bugzilla. -

2.4.3. Linux-Mandrake 8.0

Linux-Mandrake 8.0 includes every required and optional library - for Bugzilla. The easiest way to install them is by using the - urpmi utility. If you follow these commands, you - should have everything you need for Bugzilla, and - ./checksetup.pl should not complain about any - missing libraries. You may already have some of these installed. - 


bash# urpmi perl-mysql
-bash# urpmi perl-chart
-bash# urpmi perl-gd
-bash# urpmi perl-MailTools             
-bash# urpmi apache-modules
-
for Bugzilla email integration

2.5. Troubleshooting

This section gives solutions to common Bugzilla installation - problems. If none of the section headings seems to match your - problem, read the general advice. -

2.5.1. General Advice

If you can't get checksetup.pl to run to - completion, it normally explains what's wrong and how to fix it. - If you can't work it out, or if it's being uncommunicative, post - the errors in the - netscape.public.mozilla.webtools - newsgroup. -

If you have made it all the way through - Section 2.1 (Installation) and - Section 2.2 (Configuration) but - accessing the Bugzilla URL doesn't work, - the first thing to do is to check your webserver error log. For - Apache, this is often located at - /etc/logs/httpd/error_log. The error messages - you see may be self-explanatory enough to enable you to diagnose and - fix the problem. If not, see below for some commonly-encountered - errors. If that doesn't help, post the errors to the newsgroup. -

2.5.2. I installed a Perl module, but - checksetup.pl claims it's not installed!

You have two versions of Perl on your machine. You are installing - modules into one, and Bugzilla is using the other. Rerun the CPAN - commands (or manual compile) using the full path to Perl from the - top of checksetup.pl. This will make sure you - are installing the modules in the right place. -

2.5.3. Bundle::Bugzilla makes me upgrade to Perl 5.6.1

Try executing perl -MCPAN -e 'install CPAN' - and then continuing. -

Certain older versions of the CPAN toolset were somewhat naive about how - to upgrade Perl modules. When a couple of modules got rolled into the core - Perl distribution for 5.6.1, CPAN thought that the best way to get those - modules up to date was to haul down the Perl distribution itself and - build it. Needless to say, this has caused headaches for just about - everybody. Upgrading to a newer version of CPAN with the - commandline above should fix things. -

2.5.4. DBD::Sponge::db prepare failed

The following error message may appear due to a bug in DBD::mysql - (over which the Bugzilla team have no control): - 

 DBD::Sponge::db prepare failed: Cannot determine NUM_OF_FIELDS at D:/Perl/site/lib/DBD/mysql.pm line 248.
-  SV = NULL(0x0) at 0x20fc444
-  REFCNT = 1
-  FLAGS = (PADBUSY,PADMY)
-

To fix this, go to - <path-to-perl>/lib/DBD/sponge.pm - in your Perl installation and replace - 

 my $numFields;
- if ($attribs->{'NUM_OF_FIELDS'}) {
-     $numFields = $attribs->{'NUM_OF_FIELDS'};
- } elsif ($attribs->{'NAME'}) {
-     $numFields = @{$attribs->{NAME}};
-

by - 

 my $numFields;
- if ($attribs->{'NUM_OF_FIELDS'}) {
-     $numFields = $attribs->{'NUM_OF_FIELDS'};
- } elsif ($attribs->{'NAMES'}) {
-     $numFields = @{$attribs->{NAMES}};
-

(note the S added to NAME.) -

2.5.5. cannot chdir(/var/spool/mqueue)

If you are installing Bugzilla on SuSE Linux, or some other - distributions with - "paranoid" - security options, it is possible that the checksetup.pl script may fail - with the error: -
cannot chdir(/var/spool/mqueue): Permission denied
-
-

This is because your - /var/spool/mqueue - directory has a mode of - "drwx------". Type - chmod 755 - /var/spool/mqueue - - as root to fix this problem. -

2.5.6. Your vendor has not defined Fcntl macro O_NOINHERIT

This is caused by a bug in the version of - File::Temp that is distributed with perl - 5.6.0. Many minor variations of this error have been reported: - 

Your vendor has not defined Fcntl macro O_NOINHERIT, used 
-at /usr/lib/perl5/site_perl/5.6.0/File/Temp.pm line 208.
-
-Your vendor has not defined Fcntl macro O_EXLOCK, used 
-at /usr/lib/perl5/site_perl/5.6.0/File/Temp.pm line 210.
-
-Your vendor has not defined Fcntl macro O_TEMPORARY, used 
-at /usr/lib/perl5/site_perl/5.6.0/File/Temp.pm line 233.

Numerous people have reported that upgrading to version 5.6.1 - or higher solved the problem for them. A less involved fix is to apply - the following patch, which is also - available as a patch file. -

Chapter 3. Administering Bugzilla

3.1. Bugzilla Configuration

Bugzilla is configured by changing various parameters, accessed - from the "Edit parameters" link in the page footer. Here are - some of the key parameters on that page. You should run down this - list and set them appropriately after installing Bugzilla.

  1. - maintainer: - The maintainer parameter is the email address of the person - responsible for maintaining this - Bugzilla installation. The address need not be that of a valid Bugzilla - account.

  2. urlbase: - This parameter defines the fully qualified domain name and web - server path to your Bugzilla installation.

    For example, if your Bugzilla query page is - http://www.foo.com/bugzilla/query.cgi, - set your "urlbase" - to http://www.foo.com/bugzilla/.

  3. makeproductgroups: - This dictates whether or not to automatically create groups - when new products are created. -

  4. useentrygroupdefault: - Bugzilla products can have a group associated with them, so that - certain users can only see bugs in certain products. When this - parameter is set to "on", this - causes the initial group controls on newly created products - to place all newly-created bugs in the group - having the same name as the product immediately. - After a product is initially created, the group controls - can be further adjusted without interference by - this mechanism.

  5. shadowdb: - You run into an interesting problem when Bugzilla reaches a - high level of continuous activity. MySQL supports only table-level - write locking. What this means is that if someone needs to make a - change to a bug, they will lock the entire table until the operation - is complete. Locking for write also blocks reads until the write is - complete. Note that more recent versions of mysql support row level - locking using different table types. These types are slower than the - standard type, and Bugzilla does not yet take advantage of features - such as transactions which would justify this speed decrease. The - Bugzilla team are, however, happy to hear about any experiences with - row level locking and Bugzilla.

    The "shadowdb" - parameter was designed to get around this limitation. While only a - single user is allowed to write to a table at a time, reads can - continue unimpeded on a read-only shadow copy of the database. - Although your database size will double, a shadow database can cause - an enormous performance improvement when implemented on extremely - high-traffic Bugzilla databases.

    As a guide, on reasonably old hardware, mozilla.org began needing - "shadowdb" - when they reached around 40,000 Bugzilla users with several hundred - Bugzilla bug changes and comments per day.

    The value of the parameter defines the name of the - shadow bug database. You will need to set the host and port settings - from the params page, and set up replication in your database server - so that updates reach this readonly mirror. Consult your database - documentation for more detail.

  6. shutdownhtml: - - If you need to shut down Bugzilla to perform administration, enter - some descriptive HTML here and anyone who tries to use Bugzilla will - receive a page to that effect. Obviously, editparams.cgi will - still be accessible so you can remove the HTML and re-enable Bugzilla. - :-) -

  7. passwordmail: - - Every time a user creates an account, the text of - this parameter (with substitutions) is sent to the new user along with - their password message.

    Add any text you wish to the "passwordmail" parameter box. For - instance, many people choose to use this box to give a quick training - blurb about how to use Bugzilla at your site.

  8. movebugs: - - This option is an undocumented feature to allow moving bugs - between separate Bugzilla installations. You will need to understand - the source code in order to use this feature. Please consult - movebugs.pl in your Bugzilla source tree for - further documentation, such as it is. -

  9. useqacontact: - - This allows you to define an email address for each component, in - addition - to that of the default owner, who will be sent carbon copies of - incoming bugs.

  10. usestatuswhiteboard: - This defines whether you wish to have a free-form, overwritable field - associated with each bug. The advantage of the Status Whiteboard is - that it can be deleted or modified with ease, and provides an - easily-searchable field for indexing some bugs that have some trait - in common. -

  11. whinedays: - Set this to the number of days you want to let bugs go - in the NEW or REOPENED state before notifying people they have - untouched new bugs. If you do not plan to use this feature, simply do - not set up the whining cron job described in the installation - instructions, or set this value to "0" (never whine).

  12. commenton*: - All these - fields allow you to dictate what changes can pass without comment, - and which must have a comment from the person who changed them. - Often, administrators will allow users to add themselves to the CC - list, accept bugs, or change the Status Whiteboard without adding a - comment as to their reasons for the change, yet require that most - other changes come with an explanation.

    Set the "commenton" options according to your site policy. It - is a wise idea to require comments when users resolve, reassign, or - reopen bugs at the very least. -

    It is generally far better to require a developer comment - when resolving bugs than not. Few things are more annoying to bug - database users than having a developer mark a bug "fixed" without - any comment as to what the fix was (or even that it was truly - fixed!)

    -

  13. supportwatchers: - - Turning on this option allows users to ask to receive copies of - all a particular other user's bug email. This is, of - course, subject to the groupset restrictions on the bug; if the - "watcher" - would not normally be allowed to view a bug, the watcher cannot get - around the system by setting herself up to watch the bugs of someone - with bugs outside her privileges. They would still only receive email - updates for those bugs she could normally view.

3.2. User Administration

3.2.1. Creating the Default User

When you first run checksetup.pl after installing Bugzilla, it - will prompt you for the administrative username (email address) and - password for this "super user". If for some reason you delete - the "super user" account, re-running checksetup.pl will again prompt - you for this username and password.

If you wish to add more administrative users, add them to - the "admin" group and, optionally, add edit the tweakparams, editusers, - creategroups, editcomponents, and editkeywords groups to add the - entire admin group to those groups. -

3.2.2. Managing Other Users

3.2.2.1. Creating new users

Your users can create their own user accounts by clicking the - "New Account" link at the bottom of each page (assuming they - aren't logged in as someone else already.) However, should you - desire to create user accounts ahead of time, here is how you do - it.

  1. After logging in, click the "Users" link at the footer of - the query page, and then click "Add a new user".

  2. Fill out the form presented. This page is self-explanatory. - When done, click "Submit".

    Adding a user this way will - not - - send an email informing them of their username and password. - While useful for creating dummy accounts (watchers which - shuttle mail to another system, for instance, or email - addresses which are a mailing list), in general it is - preferable to log out and use the - "New Account" - - button to create users, as it will pre-populate all the - required fields and also notify the user of her account name - and password.

3.2.2.2. Modifying Users

To see a specific user, search for their login name - in the box provided on the "Edit Users" page. To see all users, - leave the box blank.

You can search in different ways the listbox to the right - of the text entry box. You can match by - case-insensitive substring (the default), - regular expression, or a - reverse - regular expression match, which finds every user name which does NOT - match the regular expression. (Please see - the man regexp - manual page for details on regular expression syntax.) -

Once you have found your user, you can change the following - fields:

  • Login Name: - This is generally the user's full email address. However, if you - have are using the emailsuffix Param, this may just be the user's - login name. Note that users can now change their login names - themselves (to any valid email address.) -

  • Real Name: The user's real name. Note that - Bugzilla does not require this to create an account.

  • Password: - You can change the user's password here. Users can automatically - request a new password, so you shouldn't need to do this often. - If you want to disable an account, see Disable Text below. -

  • Disable Text: - If you type anything in this box, including just a space, the - user is prevented from logging in, or making any changes to - bugs via the web interface. - The HTML you type in this box is presented to the user when - they attempt to perform these actions, and should explain - why the account was disabled. -

    Don't disable all the administrator accounts!

    - -

    The user can still submit bugs via - the e-mail gateway, if you set it up, even if the disabled text - field is filled in. The e-mail gateway should - not - be enabled for secure installations of Bugzilla.

    -

  • <groupname>: - If you have created some groups, e.g. "securitysensitive", then - checkboxes will appear here to allow you to add users to, or - remove them from, these groups. -

  • canconfirm: - This field is only used if you have enabled the "unconfirmed" - status. If you enable this for a user, - that user can then move bugs from "Unconfirmed" to a "Confirmed" - status (e.g.: "New" status).

  • creategroups: - This option will allow a user to create and destroy groups in - Bugzilla.

  • editbugs: - Unless a user has this bit set, they can only edit those bugs - for which they are the assignee or the reporter. Even if this - option is unchecked, users can still add comments to bugs. -

  • editcomponents: - This flag allows a user to create new products and components, - as well as modify and destroy those that have no bugs associated - with them. If a product or component has bugs associated with it, - those bugs must be moved to a different product or component - before Bugzilla will allow them to be destroyed. -

  • editkeywords: - If you use Bugzilla's keyword functionality, enabling this - feature allows a user to create and destroy keywords. As always, - the keywords for existing bugs containing the keyword the user - wishes to destroy must be changed before Bugzilla will allow it - to die.

  • editusers: - This flag allows a user to do what you're doing right now: edit - other users. This will allow those with the right to do so to - remove administrator privileges from other users or grant them to - themselves. Enable with care.

  • tweakparams: - This flag allows a user to change Bugzilla's Params - (using editparams.cgi.)

  • <productname>: - This allows an administrator to specify the products in which - a user can see bugs. The user must still have the - "editbugs" privilege to edit bugs in these products.

3.3. Products

Products - - are the broadest category in Bugzilla, and tend to represent real-world - shipping products. E.g. if your company makes computer games, - you should have one product per game, perhaps a "Common" product for - units of technology used in multiple games, and maybe a few special - products (Website, Administration...)

Many of Bugzilla's settings are configurable on a per-product - basis. The number of "votes" available to users is set per-product, - as is the number of votes - required to move a bug automatically from the UNCONFIRMED status to the - NEW status.

To create a new product:

  1. Select "products" from the footer

  2. Select the "Add" link in the bottom right

  3. Enter the name of the product and a description. The - Description field may contain HTML.

Don't worry about the "Closed for bug entry", "Maximum Votes - per person", "Maximum votes a person can put on a single bug", - "Number of votes a bug in this Product needs to automatically get out - of the UNCOMFIRMED state", and "Version" options yet. We'll cover - those in a few moments. -

3.4. Components

Components are subsections of a Product. E.g. the computer game - you are designing may have a "UI" - component, an "API" component, a "Sound System" component, and a - "Plugins" component, each overseen by a different programmer. It - often makes sense to divide Components in Bugzilla according to the - natural divisions of responsibility within your Product or - company.

Each component has a owner and (if you turned it on in the parameters), - a QA Contact. The owner should be the primary person who fixes bugs in - that component. The QA Contact should be the person who will ensure - these bugs are completely fixed. The Owner, QA Contact, and Reporter - will get email when new bugs are created in this Component and when - these bugs change. Default Owner and Default QA Contact fields only - dictate the - default assignments; - these can be changed on bug submission, or at any later point in - a bug's life.

To create a new Component:

  1. Select the "Edit components" link from the "Edit product" - page

  2. Select the "Add" link in the bottom right.

  3. Fill out the "Component" field, a short "Description", - the "Initial Owner" and "Initial QA Contact" (if enabled.) - The Component and Description fields may contain HTML; - the "Initial Owner" field must be a login name - already existing in the database. -

3.5. Versions

Versions are the revisions of the product, such as "Flinders - 3.1", "Flinders 95", and "Flinders 2000". Version is not a multi-select - field; the usual practice is to select the earliest version known to have - the bug. -

To create and edit Versions:

  1. From the "Edit product" screen, select "Edit Versions"

  2. You will notice that the product already has the default - version "undefined". Click the "Add" link in the bottom right.

  3. Enter the name of the Version. This field takes text only. - Then click the "Add" button.

3.6. Milestones

Milestones are "targets" that you plan to get a bug fixed by. For - example, you have a bug that you plan to fix for your 3.0 release, it - would be assigned the milestone of 3.0.

Milestone options will only appear for a Product if you turned - on the "usetargetmilestone" Param in the "Edit Parameters" screen. -

To create new Milestones, set Default Milestones, and set - Milestone URL:

  1. Select "Edit milestones" from the "Edit product" page.

  2. Select "Add" in the bottom right corner. - text

  3. Enter the name of the Milestone in the "Milestone" field. You - can optionally set the "sortkey", which is a positive or negative - number (-255 to 255) that defines where in the list this particular - milestone appears. This is because milestones often do not - occur in alphanumeric order For example, "Future" might be - after "Release 1.2". Select "Add".

  4. From the Edit product screen, you can enter the URL of a - page which gives information about your milestones and what - they mean.

3.7. Voting

Voting allows users to be given a pot of votes which they can allocate - to bugs, to indicate that they'd like them fixed. - This allows developers to gauge - user need for a particular enhancement or bugfix. By allowing bugs with - a certain number of votes to automatically move from "UNCONFIRMED" to - "NEW", users of the bug system can help high-priority bugs garner - attention so they don't sit for a long time awaiting triage.

To modify Voting settings:

  1. Navigate to the "Edit product" screen for the Product you - wish to modify

  2. Maximum Votes per person: - Setting this field to "0" disables voting.

  3. Maximum Votes a person can put on a single - bug: - It should probably be some number lower than the - "Maximum votes per person". Don't set this field to "0" if - "Maximum votes per person" is non-zero; that doesn't make - any sense.

  4. Number of votes a bug in this product needs to - automatically get out of the UNCONFIRMED state: - Setting this field to "0" disables the automatic move of - bugs from UNCONFIRMED to NEW. -

  5. Once you have adjusted the values to your preference, click - "Update".

3.8. Groups and Group Security

Groups allow the administrator - to isolate bugs or products that should only be seen by certain people. - The association between products and groups is controlled from - the product edit page under "Edit Group Controls." -

If the makeproductgroups param is on, a new group will be automatically - created for every new product. -

On the product edit page, there is a page to edit the - "Group Controls" - for a product and determine which groups are applicable, default, - and mandatory for each product as well as controlling entry - for each product and being able to set bugs in a product to be - totally read-only unless some group restrictions are met. -

For each group, it is possible to specify if membership in that - group is... -

  1. required for bug entry, -

  2. Not applicable to this product(NA), - a possible restriction for a member of the - group to place on a bug in this product(Shown), - a default restriction for a member of the - group to place on a bug in this product(Default), - or a mandatory restriction to be placed on bugs - in this product(Mandatory). -

  3. Not applicable by non-members to this product(NA), - a possible restriction for a non-member of the - group to place on a bug in this product(Shown), - a default restriction for a non-member of the - group to place on a bug in this product(Default), - or a mandatory restriction to be placed on bugs - in this product when entered by a non-member(Mandatory). -

  4. required in order to make any change - to bugs in this product including comments. -

To create Groups:

  1. Select the "groups" - link in the footer.

  2. Take a moment to understand the instructions on the "Edit - Groups" screen, then select the "Add Group" link.

  3. Fill out the "Group", "Description", - and "User RegExp" fields. - "User RegExp" allows you to automatically - place all users who fulfill the Regular Expression into the new group. - When you have finished, click "Add".

    If specifying a domain in the regexp, make sure you end - the regexp with a $. Otherwise, when granting access to - "@mycompany\.com", you will allow access to - 'badperson@mycompany.com.cracker.net'. You need to use - '@mycompany\.com$' as the regexp.

  4. After you add your new group, edit the new group. On the - edit page, you can specify other groups that should be included - in this group and which groups should be permitted to add and delete - users from this group.

Note that group permissions are such that you need to be a member - of all the groups a bug is in, for whatever - reason, to see that bug. Similarly, you must be a member - of all of the entry groups for a product - to add bugs to a product and you must be a member - of all of the canedit groups for a product - in order to make any change to bugs in that - product. -

3.9. Upgrading to New Releases

Upgrading is a one-way process. You should backup your database - and current Bugzilla directory before attempting the upgrade. If you wish - to revert to the old Bugzilla version for any reason, you will have to - restore from these backups. -

Upgrading Bugzilla is something we all want to do from time to time, - be it to get new features or pick up the latest security fix. How easy - it is to update depends on a few factors. -

  • If the new version is a revision or a new point release

  • How many, if any, local changes have been made

There are also three different methods to upgrade your installation. -

  1. Using CVS (Example 3-1)

  2. Downloading a new tarball (Example 3-2)

  3. Applying the relevant patches (Example 3-3)

Which options are available to you may depend on how large a jump - you are making and/or your network configuration. -

Revisions are normally released to fix security vulnerabilities - and are distinguished by an increase in the third number. For example, - when 2.16.2 was released, it was a revision to 2.16.1. -

Point releases are normally released when the Bugzilla team feels - that there has been a significant amount of progress made between the - last point release and the current time. These are often proceeded by a - stabilization period and release candidates, however the use of - development versions or release candidates is beyond the scope of this - document. Point releases can be distinguished by an increase in the - second number, or minor version. For example, 2.16.2 is a newer point - release than 2.14.5. -

The examples in this section are written as if you were updating - to version 2.16.2. The procedures are the same regardless if you are - updating to a new point release or a new revision. However, the chance - of running into trouble increases when upgrading to a new point release, - escpecially if you've made local changes. -

These examples also assume that your Bugzilla installation is at - /var/www/html/bugzilla. If that is not the case, - simply substitute the proper paths where appropriate. -

Example 3-1. Upgrading using CVS

Every release of Bugzilla, whether it is a revision or a point - release, is tagged in CVS. Also, every tarball we have distributed - since version 2.12 has been primed for using CVS. This does, however, - require that you are able to access cvs-mirror.mozilla.org on port - 2401. - -

If you can do this, updating using CVS is probably the most - painless method, especially if you have a lot of local changes. -

- 


bash$ cd /var/www/html/bugzilla
-bash$ cvs login
-Logging in to :pserver:anonymous@cvs-mirror.mozilla.org:2401/cvsroot
-CVS password: anonymous
-bash$ cvs -q update -r BUGZILLA-2_16_2 -dP
-P checksetup.pl
-P collectstats.pl
-P globals.pl
-P docs/rel_notes.txt
-P template/en/default/list/quips.html.tmpl
-

If a line in the output from cvs update - begins with a C that represents a - file with local changes that CVS was unable to properly merge. You - need to resolve these conflicts manually before Bugzilla (or at - least the portion using that file) will be usable. -

- -

You also need to run ./checksetup.pl - before your Bugzilla upgrade will be complete. -

-

Example 3-2. Upgrading using the tarball

If you are unable or unwilling to use CVS, another option that's - always available is to download the latest tarball. This is the most - difficult option to use, especially if you have local changes. - 


bash$ cd /var/www/html
-bash$ wget ftp://ftp.mozilla.org/pub/webtools/bugzilla-2.16.2.tar.gz
-Output omitted
-bash$ tar xzvf bugzilla-2.16.2.tar.gz
-bugzilla-2.16.2/
-bugzilla-2.16.2/.cvsignore
-bugzilla-2.16.2/1x1.gif
-Output truncated
-bash$ cd bugzilla-2.16.2
-bash$ cp ../bugzilla/localconfig* .
-bash$ cp -r ../bugzilla/data .
-bash$ cd ..
-bash$ mv bugzilla bugzilla.old
-bash$ mv bugzilla-2.16.2 bugzilla
-bash$ cd bugzilla
-bash$ ./checksetup.pl
-Output omitted
-

The cp commands both end with periods which - is a very important detail, it tells the shell that the destination - directory is the current working directory. Also, the period at the - beginning of the ./checksetup.pl is important and - can not be omitted. -

- -

You will now have to reapply any changes you have made to your - local installation manually. -

-

Example 3-3. Upgrading using patches

The Bugzilla team will normally make a patch file available for - revisions to go from the most recent revision to the new one. You could - also read the release notes and grab the patches attached to the - mentioned bug, but it is safer to use the released patch file as - sometimes patches get changed before they get checked in. - It is also theoretically possible to - scour the fixed bug list and pick and choose which patches to apply - from a point release, but this is not recommended either as what you'll - end up with is a hodge podge Bugzilla that isn't really any version. - This would also make it more difficult to upgrade in the future. - 


bash$ cd /var/www/html/bugzilla
-bash$ wget ftp://ftp.mozilla.org/pub/webtools/bugzilla-2.16.1-to-2.16.2.diff.gz
-Output omitted
-bash$ gunzip bugzilla-2.16.1-to-2.16.2.diff.gz
-bash$ patch -p1 < bugzilla-2.16.1-to-2.16.2.diff
-patching file checksetup.pl
-patching file collectstats.pl
-patching file globals.pl
-

If you do this, beware that this doesn't change the entires in - your CVS directory so it may make - updates using CVS (Example 3-1) more difficult in the - future. -

-

Chapter 4. Customising Bugzilla

4.1. Template Customization

Administrators can configure the look and feel of Bugzilla without - having to edit Perl files or face the nightmare of massive merge - conflicts when they upgrade to a newer version in the future. -

Templatization also makes localized versions of Bugzilla possible, - for the first time. It's possible to have Bugzilla's UI language - determined by the user's browser. More information is available in - Section 4.1.5. -

4.1.1. What to Edit

The template directory structure is that there's a top level directory, - template, which contains a directory for - each installed localization. The default English templates are - therefore in en. Underneath that, there - is the default directory and optionally the - custom directory. The default - directory contains all the templates shipped with Bugzilla, whereas - the custom directory does not exist at first and - must be created if you want to use it. -

There are two different ways of editing Bugzilla's templates, - and which you use depends mainly on the method you plan to use to - upgrade Bugzilla. - The first method of making customizations is to directly edit the - templates in template/en/default. This is - probably the best method for small changes if you are going to use - the CVS method of upgrading, because if you then execute a - cvs update, any template fixes will get - automagically merged into your modified versions. -

If you use this method, your installation will break if CVS conflicts - occur. -

The other method is to copy the templates to be modified into a - mirrored directory - structure under template/en/custom. The templates - in this directory automatically override those in default. - This is the technique you - need to use if you use the overwriting method of upgrade, because - otherwise your changes will be lost. This method is also better if - you are using the CVS method of upgrading and are going to make major - changes, because it is guaranteed that the contents of this directory - will not be touched during an upgrade, and you can then decide whether - to continue using your own templates, or make the effort to merge your - changes into the new versions by hand. -

If you use this method, your installation may break if incompatible - changes are made to the template interface. If such changes are made - they will be documented in the release notes, provided you are using a - stable release of Bugzilla. If you use using unstable code, you will - need to deal with this one yourself, although if possible the changes - will be mentioned before they occur in the deprecations section of the - previous stable release's release notes. -

Don't directly edit the compiled templates in - data/template/* - your - changes will be lost when Template Toolkit recompiles them. -

It is recommended that you run ./checksetup.pl - after any template edits, especially if you've created a new file in - the custom directory. -

4.1.2. How To Edit Templates

If you are making template changes that you intend on submitting back - for inclusion in standard Bugzilla, you should read the relevant - sections of the - Developers' - Guide. -

The syntax of the Template Toolkit language is beyond the scope of - this guide. It's reasonably easy to pick up by looking at the current - templates; or, you can read the manual, available on the - Template Toolkit home - page. -

One thing you should take particular care about is the need - to properly HTML filter data that has been passed into the template. - This means that if the data can possibly contain special HTML characters - such as <, and the data was not intended to be HTML, they need to be - converted to entity form, ie &lt;. You use the 'html' filter in the - Template Toolkit to do this. If you forget, you may open up - your installation to cross-site scripting attacks. -

Also note that Bugzilla adds a few filters of its own, that are not - in standard Template Toolkit. In particular, the 'url_quote' filter - can convert characters that are illegal or have special meaning in URLs, - such as &, to the encoded form, ie %26. This actually encodes most - characters (but not the common ones such as letters and numbers and so - on), including the HTML-special characters, so there's never a need to - HTML filter afterwards. -

Editing templates is a good way of doing a "poor man's custom fields". - For example, if you don't use the Status Whiteboard, but want to have - a free-form text entry box for "Build Identifier", then you can just - edit the templates to change the field labels. It's still be called - status_whiteboard internally, but your users don't need to know that. -

4.1.3. Template Formats

Some CGIs have the ability to use more than one template. For - example, buglist.cgi can output bug lists as RDF or two - different forms of HTML (complex and simple). (Try this out - by appending &format=simple to a buglist.cgi - URL on your Bugzilla installation.) This - mechanism, called template 'formats', is extensible. -

To see if a CGI supports multiple output formats, grep the - CGI for "GetFormat". If it's not present, adding - multiple format support isn't too hard - see how it's done in - other CGIs, e.g. config.cgi. -

To make a new format template for a CGI which supports this, - open a current template for - that CGI and take note of the INTERFACE comment (if present.) This - comment defines what variables are passed into this template. If - there isn't one, I'm afraid you'll have to read the template and - the code to find out what information you get. -

Write your template in whatever markup or text style is appropriate. -

You now need to decide what content type you want your template - served as. Open up the localconfig file and find the - $contenttypes - variable. If your content type is not there, add it. Remember - the three- or four-letter tag assigned to you content type. - This tag will be part of the template filename. -

Save the template as <stubname>-<formatname>.<contenttypetag>.tmpl. - Try out the template by calling the CGI as - <cginame>.cgi?format=<formatname> . -

4.1.4. Particular Templates

There are a few templates you may be particularly interested in - customizing for your installation. -

index.html.tmpl: - This is the Bugzilla front page. -

global/header.html.tmpl: - This defines the header that goes on all Bugzilla pages. - The header includes the banner, which is what appears to users - and is probably what you want to edit instead. However the - header also includes the HTML HEAD section, so you could for - example add a stylesheet or META tag by editing the header. -

global/banner.html.tmpl: - This contains the "banner", the part of the header that appears - at the top of all Bugzilla pages. The default banner is reasonably - barren, so you'll probably want to customize this to give your - installation a distinctive look and feel. It is recommended you - preserve the Bugzilla version number in some form so the version - you are running can be determined, and users know what docs to read. -

global/footer.html.tmpl: - This defines the footer that goes on all Bugzilla pages. Editing - this is another way to quickly get a distinctive look and feel for - your Bugzilla installation. -

bug/create/user-message.html.tmpl: - This is a message that appears near the top of the bug reporting page. - By modifying this, you can tell your users how they should report - bugs. -

bug/create/create.html.tmpl and - bug/create/comment.txt.tmpl: - You may wish to get bug submitters to give certain bits of structured - information, each in a separate input widget, for which there is not a - field in the database. The bug entry system has been designed in an - extensible fashion to enable you to define arbitrary fields and widgets, - and have their values appear formatted in the initial - Description, rather than in database fields. An example of this - is the mozilla.org - guided - bug submission form. -

To make this work, create a custom template for - enter_bug.cgi (the default template, on which you - could base it, is create.html.tmpl), - and either call it create.html.tmpl or use a format and - call it create-<formatname>.html.tmpl. - Put it in the custom/bug/create - directory. In it, add widgets for each piece of information you'd like - collected - such as a build number, or set of steps to reproduce. -

Then, create a template like - custom/bug/create/comment.txt.tmpl, also named - after your format if you are using one, which - references the form fields you have created. When a bug report is - submitted, the initial comment attached to the bug report will be - formatted according to the layout of this template. -

For example, if your enter_bug template had a field - 
<input type="text" name="buildid" size="30">
- and then your comment.txt.tmpl had - 
BuildID: [% form.buildid %]
- then - 
BuildID: 20020303
- would appear in the initial checkin comment. -

4.1.5. Configuring Bugzilla to Detect the User's Language

Bugzilla honours the user's Accept: HTTP header. You can install - templates in other languages, and Bugzilla will pick the most appropriate - according to a priority order defined by you. Many - language templates can be obtained from http://www.bugzilla.org/download.html#localizations. Instructions - for submitting new languages are also available from that location. -

After untarring the localizations (or creating your own) in the - BUGZILLA_ROOT/template directory, - you must update the languages parameter to contain any - localizations you'd like to permit. You may also wish to set the - defaultlanguage parameter to something other than - "en" if you don't want Engish to be the default language. -

4.2. Template Hooks

Template hooks are a way for extensions to Bugzilla to insert code - into the standard Bugzilla templates without modifying the template files - themselves. The hooks mechanism defines a consistent API for extending - the standard templates in a way that cleanly separates standard code - from extension code. Hooks reduce merge conflicts and make it easier - to write extensions that work across multiple versions of Bugzilla, - making upgrading a Bugzilla installation with installed extensions easier. -

A template hook is just a named place in a standard template file - where extension template files for that hook get processed. Each hook - has a corresponding directory in the Bugzilla directory tree. Hooking an - extension template to a hook is as simple as putting the extension file - into the hook's directory. When Bugzilla processes the standard template - and reaches the hook, it will process all extension templates in the - hook's directory. The hooks themselves can be added into any standard - template upon request by extension authors. -

To use hooks to extend a Bugzilla template, first make sure there is - a hook at the appropriate place within the template you want to extend. - Hooks appear in the standard Bugzilla templates as a single directive - in the format - [% Hook.process("name") %], - where name is the unique (within that template) - name of the hook. -

If you aren't sure which template you want to extend or just want - to browse the available hooks, either use your favorite multi-file search - tool (e.g. grep) to search the standard templates - for occurrences of Hook.process or browse - the directory tree in - BUGZILLA_ROOT/template/en/extension/hook/, - which contains a directory for each hook in the following location: -

BUGZILLA_ROOT/template/en/extension/hook/PATH_TO_STANDARD_TEMPLATE/STANDARD_TEMPLATE_NAME/HOOK_NAME/ -

If there is no hook at the appropriate place within the Bugzilla template - you want to extend, - file - a bug requesting one, specifying: -

the template for which you are requesting a hook;
where in the template you would like the hook to be placed - (line number/position for latest version of template in CVS - or description of location); -
the purpose of the hook;
a link to information about your extension, if any.

The Bugzilla reviewers will promptly review each hook request, - name the hook, add it to the template, check the new version - of the template into CVS, and create the corresponding directory in - BUGZILLA_ROOT/template/en/extension/hook/. -

You may optionally attach a patch to the bug which implements the hook - and check it in yourself after receiving approval from a Bugzilla - reviewer. The developers may suggest changes to the location of the - hook based on their analysis of your needs or so the hook can satisfy - the needs of multiple extensions, but the process of getting hooks - approved and checked in is not as stringent as the process for general - changes to Bugzilla, and any extension, whether released or still in - development, can have hooks added to meet their needs. -

After making sure the hook you need exists (or getting it added if not), - add your extension template to the directory within the Bugzilla - directory tree corresponding to the hook. -

That's it! Now, when the standard template containing the hook - is processed, your extension template will be processed at the point - where the hook appears. -

For example, let's say you have an extension named Projman that adds - project management capabilities to Bugzilla. Projman has an - administration interface edit-projects.cgi, - and you want to add a link to it into the navigation bar at the bottom - of every Bugzilla page for those users who are authorized - to administer projects. -

The navigation bar is generated by the template file - useful-links.html.tmpl, which is located in - the global/ subdirectory on the standard Bugzilla - template path - BUGZILLA_ROOT/template/en/default/. - Looking in useful-links.html.tmpl, you find - the following hook at the end of the list of standard Bugzilla - administration links: - 

...
-    [% ', <a href="editkeywords.cgi">keywords</a>' 
-                                              IF user.groups.editkeywords %]
-    [% Hook.process("edit") %]
-...

The corresponding directory for this hook is - BUGZILLA_ROOT/template/en/extension/hook/global/useful-links.html.tmpl/edit/. -

You put a template named - projman-edit-projects.html.tmpl - into that directory with the following content: - 

...[% ', <a href="edit-projects.cgi">projects</a>' IF user.groups.projman_admins %]

Voila! The link now appears after the other administration links in the - navigation bar for users in the projman_admins group. -

Notes: -

  • You may want to prefix your extension template names - with the name of your extension, e.g. - projman-foo.html.tmpl, - so they do not conflict with the names of templates installed by - other extensions. -

  • If your extension includes entirely new templates in addition to - extensions of standard templates, it should install those new - templates into an extension-specific subdirectory of the - BUGZILLA_ROOT/template/en/extension/ - directory. The extension/ directory, like the - default/ and custom/ - directories, is part of the template search path, so putting templates - there enables them to be found by the template processor. -

    The template processor looks for templates first in the - custom/ directory (i.e. templates added by the - specific installation), then in the extension/ - directory (i.e. templates added by extensions), and finally in the - default/ directory (i.e. the standard Bugzilla - templates). Thus extension templates can override standard templates, - but installation-specific templates override both. -

    Note that overriding standard templates with extension templates - gives you great power but also makes upgrading an installation harder. - As with custom templates, we recommend using this functionality - sparingly and only when absolutely necessary. -

  • Installation customizers can also take advantage of hooks when adding - code to a Bugzilla template. To do so, create directories in - BUGZILLA_ROOT/template/en/custom/hook/ - equivalent to the directories in - BUGZILLA_ROOT/template/en/extension/hook/ - for the hooks you want to use, then place your customization templates - into those directories. -

    Obviously this method of customizing Bugzilla only lets you add code - to the standard templates; you cannot change the existing code. - Nevertheless, for those customizations that only add code, this method - can reduce conflicts when merging changes, making upgrading - your customized Bugzilla installation easier. -

4.3. Customizing Who Can Change What

This feature should be considered experimental; the Bugzilla code you - will be changing is not stable, and could change or move between - versions. Be aware that if you make modifications as outlined here, - you may have - to re-make them or port them if Bugzilla changes internally between - versions, and you upgrade. -

Companies often have rules about which employees, or classes of employees, - are allowed to change certain things in the bug system. For example, - only the bug's designated QA Contact may be allowed to VERIFY the bug. - Bugzilla has been - designed to make it easy for you to write your own custom rules to define - who is allowed to make what sorts of value transition. -

For maximum flexibility, customizing this means editing Bugzilla's Perl - code. This gives the administrator complete control over exactly who is - allowed to do what. The relevant function is called - CheckCanChangeField(), - and is found in process_bug.cgi in your - Bugzilla directory. If you open that file and grep for - "sub CheckCanChangeField", you'll find it. -

This function has been carefully commented to allow you to see exactly - how it works, and give you an idea of how to make changes to it. Certain - marked sections should not be changed - these are the "plumbing" which - makes the rest of the function work. In between those sections, you'll - find snippets of code like: - 
    # Allow the owner to change anything.
-    if ($ownerid eq $whoid) {
-        return 1;
-    }
- It's fairly obvious what this piece of code does. -

So, how does one go about changing this function? Well, simple changes - can be made just be removing pieces - for example, if you wanted to - prevent any user adding a comment to a bug, just remove the lines marked - "Allow anyone to change comments." And if you want the reporter to have - no special rights on bugs they have filed, just remove the entire section - which refers to him. -

More complex customizations are not much harder. Basically, you add - a check in the right place in the function, i.e. after all the variables - you are using have been set up. So, don't look at $ownerid before - $ownerid has been obtained from the database. You can either add a - positive check, which returns 1 (allow) if certain conditions are true, - or a negative check, which returns 0 (deny.) E.g.: - 
    if ($field eq "qacontact") {
-        if (Bugzilla->user->groups("quality_assurance")) {
-            return 1;
-        } 
-        else {
-            return 0;
-        }
-    }
- This says that only users in the group "quality_assurance" can change - the QA Contact field of a bug. Getting more weird: - 
    if (($field eq "priority") &&
-        (Bugzilla->user->email =~ /.*\@example\.com$/))
-    {
-        if ($oldvalue eq "P1") {
-            return 1;
-        } 
-        else {
-            return 0;
-        }
-    }
- This says that if the user is trying to change the priority field, - and their email address is @example.com, they can only do so if the - old value of the field was "P1". Not very useful, but illustrative. -

For a list of possible field names, look in - data/versioncache for the list called - @::log_columns. If you need help writing custom - rules for your organization, ask in the newsgroup. -

4.4. Modifying Your Running System

Bugzilla optimizes database lookups by storing all relatively - static information in the - versioncache file, located in the - data/ - subdirectory under your installation directory.

If you make a change to the structural data in your database (the - versions table for example), or to the - "constants" - - encoded in defparams.pl, you will need to remove - the cached content from the data directory (by doing a - "rm data/versioncache" - - ), or your changes won't show up.

versioncache - gets automatically regenerated whenever it's more than - an hour old, so Bugzilla will eventually notice your changes by itself, - but generally you want it to notice right away, so that you can test - things.

4.5. MySQL Bugzilla Database Introduction

This information comes straight from my life. I was forced to learn - how Bugzilla organizes database because of nitpicky requests from users - for tiny changes in wording, rather than having people re-educate - themselves or figure out how to work our procedures around the tool. It - sucks, but it can and will happen to you, so learn how the schema works - and deal with it when it comes.

So, here you are with your brand-new installation of Bugzilla. - You've got MySQL set up, Apache working right, Perl DBI and DBD talking - to the database flawlessly. Maybe you've even entered a few test bugs to - make sure email's working; people seem to be notified of new bugs and - changes, and you can enter and edit bugs to your heart's content. Perhaps - you've gone through the trouble of setting up a gateway for people to - submit bugs to your database via email, have had a few people test it, - and received rave reviews from your beta testers.

What's the next thing you do? Outline a training strategy for your - development team, of course, and bring them up to speed on the new tool - you've labored over for hours.

Your first training session starts off very well! You have a - captive audience which seems enraptured by the efficiency embodied in - this thing called "Bugzilla". You are caught up describing the nifty - features, how people can save favorite queries in the database, set them - up as headers and footers on their pages, customize their layouts, - generate reports, track status with greater efficiency than ever before, - leap tall buildings with a single bound and rescue Jane from the clutches - of Certain Death!

But Certain Death speaks up -- a tiny voice, from the dark corners - of the conference room. "I have a concern," the voice hisses from the - darkness, "about the use of the word 'verified'."

The room, previously filled with happy chatter, lapses into - reverential silence as Certain Death (better known as the Vice President - of Software Engineering) continues. "You see, for two years we've used - the word 'verified' to indicate that a developer or quality assurance - engineer has confirmed that, in fact, a bug is valid. I don't want to - lose two years of training to a new software product. You need to change - the bug status of 'verified' to 'approved' as soon as possible. To avoid - confusion, of course."

Oh no! Terror strikes your heart, as you find yourself mumbling - "yes, yes, I don't think that would be a problem," You review the changes - with Certain Death, and continue to jabber on, "no, it's not too big a - change. I mean, we have the source code, right? You know, 'Use the - Source, Luke' and all that... no problem," All the while you quiver - inside like a beached jellyfish bubbling, burbling, and boiling on a hot - Jamaican sand dune...

Thus begins your adventure into the heart of Bugzilla. You've been - forced to learn about non-portable enum() fields, varchar columns, and - tinyint definitions. The Adventure Awaits You!

4.5.1. Bugzilla Database Basics

If you were like me, at this point you're totally clueless about - the internals of MySQL, and if it weren't for this executive order from - the Vice President you couldn't care less about the difference between - a - "bigint" - - and a - "tinyint" - - entry in MySQL. I recommend you refer to the - MySQL documentation - . Below are the basics you need to know about the Bugzilla database. - Check the chart above for more details.

  1. To connect to your database:

    bash# - - mysql - - -u root -

    If this works without asking you for a password, - shame on you - - ! You should have locked your security down like the installation - instructions told you to. You can find details on locking down - your database in the Bugzilla FAQ in this directory (under - "Security"), or more robust security generalities in the - MySQL - searchable documentation. -

  2. You should now be at a prompt that looks like this:

    mysql> -

    At the prompt, if - "bugs" - - is the name you chose in the - localconfig - - file for your Bugzilla database, type:

    mysql - - use bugs; -

-

4.5.1.1. Bugzilla Database Tables

Imagine your MySQL database as a series of spreadsheets, and - you won't be too far off. If you use this command:

mysql> - show tables from bugs; -

you'll be able to see the names of all the - "spreadsheets" - (tables) in your database.

From the command issued above, ou should have some - output that looks like this: -

+-------------------+
-| Tables in bugs    |
-+-------------------+
-| attachments       |
-| bugs              |

-
-


-  Here's an overview of what each table does. Most columns in each table have
-descriptive names that make it fairly trivial to figure out their jobs.
-
-attachments: This table stores all attachments to bugs. It tends to be your
-largest table, yet also generally has the fewest entries because file
-attachments are so (relatively) large.
-
-bugs:  This is the core of your system. The bugs table stores most of the
-current information about a bug, with the exception of the info stored in the
-other tables.
-
-bugs_activity:  This stores information regarding what changes are made to bugs
-when -- a history file.
-
-cc:  This tiny table simply stores all the CC information for any bug which has
-any entries in the CC field of the bug. Note that, like most other tables in
-Bugzilla, it does not refer to users by their user names, but by their unique
-userid, stored as a primary key in the profiles table.
-
-components: This stores the programs and components (or products and
-components, in newer Bugzilla parlance) for Bugzilla. Curiously, the "program"
-(product) field is the full name of the product, rather than some other unique
-identifier, like bug_id and user_id are elsewhere in the database.
-
-dependencies: Stores data about those cool dependency trees.
-
-fielddefs:  A nifty table that defines other tables. For instance, when you
-submit a form that changes the value of "AssignedTo" this table allows
-translation to the actual field name "assigned_to" for entry into MySQL.
-
-groups:  defines bitmasks for groups. A bitmask is a number that can uniquely
-identify group memberships. For instance, say the group that is allowed to
-tweak parameters is assigned a value of "1", the group that is allowed to edit
-users is assigned a "2", and the group that is allowed to create new groups is
-assigned the bitmask of "4". By uniquely combining the group bitmasks (much
-like the chmod command in UNIX,) you can identify a user is allowed to tweak
-parameters and create groups, but not edit users, by giving him a bitmask of
-"5", or a user allowed to edit users and create groups, but not tweak
-parameters, by giving him a bitmask of "6" Simple, huh?
-  If this makes no sense to you, try this at the mysql prompt:
-mysql> select * from groups;
-  You'll see the list, it makes much more sense that way.
-
-keyworddefs:  Definitions of keywords to be used
-
-keywords: Unlike what you'd think, this table holds which keywords are
-associated with which bug id's.
-
-logincookies: This stores every login cookie ever assigned to you for every
-machine you've ever logged into Bugzilla from. Curiously, it never does any
-housecleaning -- I see cookies in this file I've not used for months. However,
-since Bugzilla never expires your cookie (for convenience' sake), it makes
-sense.
-
-longdescs:  The meat of bugzilla -- here is where all user comments are stored!
-You've only got 2^24 bytes per comment (it's a mediumtext field), so speak
-sparingly -- that's only the amount of space the Old Testament from the Bible
-would take (uncompressed, 16 megabytes). Each comment is keyed to the
-bug_id to which it's attached, so the order is necessarily chronological, for
-comments are played back in the order in which they are received.
-
-milestones:  Interesting that milestones are associated with a specific product
-in this table, but Bugzilla does not yet support differing milestones by
-product through the standard configuration interfaces.
-
-namedqueries:  This is where everybody stores their "custom queries". Very
-cool feature; it beats the tar out of having to bookmark each cool query you
-construct.
-
-products:  What products you have, whether new bug entries are allowed for the
-product, what milestone you're working toward on that product, votes, etc. It
-will be nice when the components table supports these same features, so you
-could close a particular component for bug entry without having to close an
-entire product...
-
-profiles:  Ahh, so you were wondering where your precious user information was
-stored?  Here it is!  With the passwords in plain text for all to see! (but
-sshh... don't tell your users!)
-
-profiles_activity:  Need to know who did what when to who's profile?  This'll
-tell you, it's a pretty complete history.
-
-versions:  Version information for every product
-
-votes:  Who voted for what when
-
-watch:  Who (according to userid) is watching who's bugs (according to their
-userid).
-
-
-===
-THE DETAILS
-===
-
-  Ahh, so you're wondering just what to do with the information above?  At the
-mysql prompt, you can view any information about the columns in a table with
-this command (where "table" is the name of the table you wish to view):
-
-mysql> show columns from table;
-
-  You can also view all the data in a table with this command:
-
-mysql> select * from table;
-
-  -- note: this is a very bad idea to do on, for instance, the "bugs" table if
-you have 50,000 bugs. You'll be sitting there a while until you ctrl-c or
-50,000 bugs play across your screen.
-
-  You can limit the display from above a little with the command, where
-"column" is the name of the column for which you wish to restrict information:
-
-mysql> select * from table where (column = "some info");
-
-  -- or the reverse of this
-
-mysql> select * from table where (column != "some info");
-
-  Let's take our example from the introduction, and assume you need to change
-the word "verified" to "approved" in the resolution field. We know from the
-above information that the resolution is likely to be stored in the "bugs"
-table. Note we'll need to change a little perl code as well as this database
-change, but I won't plunge into that in this document. Let's verify the
-information is stored in the "bugs" table:
-
-mysql> show columns from bugs
-
-  (exceedingly long output truncated here)
-| bug_status| enum('UNCONFIRMED','NEW','ASSIGNED','REOPENED','RESOLVED','VERIFIED','CLOSED')||MUL | UNCONFIRMED||
-
-  Sorry about that long line. We see from this that the "bug status" column is
-an "enum field", which is a MySQL peculiarity where a string type field can
-only have certain types of entries. While I think this is very cool, it's not
-standard SQL. Anyway, we need to add the possible enum field entry
-'APPROVED' by altering the "bugs" table.
-
-mysql> ALTER table bugs CHANGE bug_status bug_status
-    -> enum("UNCONFIRMED", "NEW", "ASSIGNED", "REOPENED", "RESOLVED",
-    -> "VERIFIED", "APPROVED", "CLOSED") not null;
-
-    (note we can take three lines or more -- whatever you put in before the
-semicolon is evaluated as a single expression)
-
-Now if you do this:
-
-mysql> show columns from bugs;
-
-  you'll see that the bug_status field has an extra "APPROVED" enum that's
-available!  Cool thing, too, is that this is reflected on your query page as
-well -- you can query by the new status. But how's it fit into the existing
-scheme of things?
-  Looks like you need to go back and look for instances of the word "verified"
-in the perl code for Bugzilla -- wherever you find "verified", change it to
-"approved" and you're in business (make sure that's a case-insensitive search).
-Although you can query by the enum field, you can't give something a status
-of "APPROVED" until you make the perl changes. Note that this change I
-mentioned can also be done by editing checksetup.pl, which automates a lot of
-this. But you need to know this stuff anyway, right?

4.6. Integrating Bugzilla with Third-Party Tools

4.6.1. Bonsai

Bonsai is a web-based tool for managing - CVS, the Concurrent Versioning System - - . Using Bonsai, administrators can control open/closed status of trees, - query a fast relational database back-end for change, branch, and comment - information, and view changes made since the last time the tree was - closed. Bonsai - also integrates with - Tinderbox, the Mozilla automated build management system. -

4.6.2. CVS

CVS integration is best accomplished, at this point, using the - Bugzilla Email Gateway.

Follow the instructions in this Guide for enabling Bugzilla e-mail - integration. Ensure that your check-in script sends an email to your - Bugzilla e-mail gateway with the subject of - "[Bug XXXX]", - and you can have CVS check-in comments append to your Bugzilla bug. If - you want to have the bug be closed automatically, you'll have to modify - the contrib/bugzilla_email_append.pl script. -

There is also a CVSZilla project, based upon somewhat dated - Bugzilla code, to integrate CVS and Bugzilla through CVS' ability to - email. Check it out at: http://homepages.kcbbs.gen.nz/~tonyg/. -

4.6.3. Perforce SCM

You can find the project page for Bugzilla and Teamtrack Perforce - integration (p4dti) at: - http://www.ravenbrook.com/project/p4dti/ - - . - "p4dti" - - is now an officially supported product from Perforce, and you can find - the "Perforce Public Depot" p4dti page at - http://public.perforce.com/public/perforce/p4dti/index.html - - .

Integration of Perforce with Bugzilla, once patches are applied, is - seamless. Perforce replication information will appear below the comments - of each bug. Be certain you have a matching set of patches for the - Bugzilla version you are installing. p4dti is designed to support - multiple defect trackers, and maintains its own documentation for it. - Please consult the pages linked above for further information.

4.6.4. Tinderbox/Tinderbox2

Tinderbox is a continuous-build system which can integrate with - Bugzilla - see - http://www.mozilla.org/projects/tinderbox for details - of Tinderbox, and - http://tinderbox.mozilla.org/showbuilds.cgi to see it - in action.

Chapter 5. Using Bugzilla

5.1. Introduction

This section contains information for end-users of Bugzilla. - There is a Bugzilla test installation, called - Landfill, - which you are welcome to play with (if it's up.) - However, it does not necessarily - have all Bugzilla features enabled, and runs an up-to-the-minute version, - so some things may not quite work as this document describes.

5.2. Create a Bugzilla Account

If you want to use Bugzilla, first you need to create an account. - Consult with the administrator responsible for your installation of - Bugzilla for the URL you should use to access it. If you're - test-driving Bugzilla, use this URL: - http://landfill.bugzilla.org/bugzilla-tip/. -

  1. Click the - "Open a new Bugzilla account" - - link, enter your email address and, optionally, your name in the - spaces provided, then click - "Create Account" - - .

  2. Within moments, you should receive an email to the address - you provided, which contains your login name (generally the - same as the email address), and a password. - This password is randomly generated, but can be - changed to something more memorable.

  3. Click the - "Log In" - link in the footer at the bottom of the page in your browser, - enter your email address and password into the spaces provided, and - click - "Login". -

You are now logged in. Bugzilla uses cookies to remember you are - logged in so, unless you have cookies disabled or your IP address changes, - you should not have to log in again.

5.3. Anatomy of a Bug

The core of Bugzilla is the screen which displays a particular - bug. It's a good place to explain some Bugzilla concepts. - Bug 1 on Landfill - - is a good example. Note that the labels for most fields are hyperlinks; - clicking them will take you to context-sensitive help on that - particular field. Fields marked * may not be present on every - installation of Bugzilla.

  1. Product and Component: - Bugs are divided up by Product and Component, with a Product - having one or more Components in it. For example, - bugzilla.mozilla.org's "Bugzilla" Product is composed of several - Components: -

    Administration: - Administration of a Bugzilla installation.
    Bugzilla-General: - Anything that doesn't fit in the other components, or spans - multiple components.
    Creating/Changing Bugs: - Creating, changing, and viewing bugs.
    Documentation: - The Bugzilla documentation, including The Bugzilla Guide.

    -

  2. Status and Resolution: - - These define exactly what state the bug is in - from not even - being confirmed as a bug, through to being fixed and the fix - confirmed by Quality Assurance. The different possible values for - Status and Resolution on your installation should be documented in the - context-sensitive help for those items.

  3. Assigned To: - The person responsible for fixing the bug.

  4. *URL: - A URL associated with the bug, if any.

  5. Summary: - A one-sentence summary of the problem.

  6. *Status Whiteboard: - (a.k.a. Whiteboard) A free-form text area for adding short notes - and tags to a bug.

  7. *Keywords: - The administrator can define keywords which you can use to tag and - categorise bugs - e.g. The Mozilla Project has keywords like crash - and regression.

  8. Platform and OS: - These indicate the computing environment where the bug was - found.

  9. Version: - The "Version" field is usually used for versions of a product which - have been released, and is set to indicate which versions of a - Component have the particular problem the bug report is - about.

  10. Priority: - The bug assignee uses this field to prioritise his or her bugs. - It's a good idea not to change this on other people's bugs.

  11. Severity: - This indicates how severe the problem is - from blocker - ("application unusable") to trivial ("minor cosmetic issue"). You - can also use this field to indicate whether a bug is an enhancement - request.

  12. *Target: - (a.k.a. Target Milestone) A future version by which the bug is to - be fixed. e.g. The Bugzilla Project's milestones for future - Bugzilla versions are 2.18, 2.20, 3.0, etc. Milestones are not - restricted to numbers, thought - you can use any text strings, such - as dates.

5.4. Searching for Bugs

The Bugzilla Search page is is the interface where you can find - any bug report, comment, or patch currently in the Bugzilla system. You - can play with it here: - http://landfill.bugzilla.org/bugzilla-tip/query.cgi.

The Search page has controls for selecting different possible - values for all of the fields in a bug, as described above. For some - fields, multiple values can be selected. In those cases, Bugzilla - returns bugs where the content of the field matches any one of the selected - values. If none is selected, then the field can take any value.

Once you've run a search, you can save it as a Saved Search, which - appears in the page footer.

Highly advanced querying is done using Boolean Charts. See the - Boolean Charts help link on the Search page for more information.

5.5. Bug Lists

If you run a search, a list of matching bugs will be returned. -

The format of the list is configurable. For example, it can be - sorted by clicking the column headings. Other useful features can be - accessed using the links at the bottom of the list: -

Long Format: - - this gives you a large page with a non-editable summary of the fields - of each bug.
CSV: - - get the buglist as comma-separated values, for import into e.g. - a spreadsheet.
Change Columns: - - change the bug attributes which appear in the list.
Change several bugs at once: - - If your account is sufficiently empowered, you can make the same - change to all the bugs in the list - for example, changing their - owner.
Send mail to bug owners: - - Sends mail to the owners of all bugs on the list.
Edit Search: - - If you didn't get exactly the results you were looking for, you can - return to the Query page through this link and make small revisions - to the query you just made so you get more accurate results.
Remember Search As: - - You can give a search a name and remember it; a link will appear - in your page footer giving you quick access to run it again later. -

-

5.6. Filing Bugs

Years of bug writing experience has been distilled for your - reading pleasure into the - Bug Writing Guidelines. - While some of the advice is Mozilla-specific, the basic principles of - reporting Reproducible, Specific bugs, isolating the Product you are - using, the Version of the Product, the Component which failed, the - Hardware Platform, and Operating System you were using at the time of - the failure go a long way toward ensuring accurate, responsible fixes - for the bug that bit you.

The procedure for filing a test bug is as follows:

  1. Go to - Landfill - in your browser and click - Enter a new bug report. -

  2. Select a product - any one will do.

  3. Fill in the fields. Bugzilla should have made reasonable - guesses, based upon your browser, for the "Platform" and "OS" - drop-down boxes. If they are wrong, change them.

  4. Select "Commit" and send in your bug report.

Try to make sure that everything said in the summary is also - said in the first comment. Summaries are often updated and this will - ensure your original information is easily accessible. -

You do not need to put "any" or similar strings in the URL field. - If there is no specific URL associated with the bug, leave this - field blank. -

If you feel a bug you filed was incorrectly marked as a - DUPLICATE of another, please question it in your bug, not - the bug it was duped to. Feel free to CC the person who duped it - if they are not already CCed. -

5.7. Patch Viewer

Viewing and reviewing patches in Bugzilla is often difficult due to - lack of context, improper format and the inherent readability issues that - raw patches present. Patch Viewer is an enhancement to Bugzilla designed - to fix that by offering increased context, linking to sections, and - integrating with Bonsai, LXR and CVS.

Patch viewer allows you to:

View patches in color, with side-by-side view rather than trying - to interpret the contents of the patch.
See the difference between two patches.
Get more context in a patch.
Collapse and expand sections of a patch for easy - reading.
Link to a particular section of a patch for discussion or - review
Go to Bonsai or LXR to see more context, blame, and - cross-references for the part of the patch you are looking at
Create a rawtext unified format diff out of any patch, no - matter what format it came from

5.7.1. Viewing Patches in Patch Viewer

The main way to view a patch in patch viewer is to click on the - "Diff" link next to a patch in the Attachments list on a bug. You may - also do this within the edit window by clicking the "View Attachment As - Diff" button in the Edit Attachment screen.

5.7.2. Seeing the Difference Between Two Patches

To see the difference between two patches, you must first view the - newer patch in Patch Viewer. Then select the older patch from the - dropdown at the top of the page ("Differences between [dropdown] and - this patch") and click the "Diff" button. This will show you what - is new or changed in the newer patch.

5.7.3. Getting More Context in a Patch

To get more context in a patch, you put a number in the textbox at - the top of Patch Viewer ("Patch / File / [textbox]") and hit enter. - This will give you that many lines of context before and after each - change. Alternatively, you can click on the "File" link there and it - will show each change in the full context of the file. This feature only - works against files that were diffed using "cvs diff".

5.7.4. Collapsing and Expanding Sections of a Patch

To view only a certain set of files in a patch (for example, if a - patch is absolutely huge and you want to only review part of it at a - time), you can click the "(+)" and "(-)" links next to each file (to - expand it or collapse it). If you want to collapse all files or expand - all files, you can click the "Collapse All" and "Expand All" links at the - top of the page.

5.7.5. Linking to a Section of a Patch

To link to a section of a patch (for example, if you want to be - able to give someone a URL to show them which part you are talking - about) you simply click the "Link Here" link on the section header. The - resulting URL can be copied and used in discussion. (Copy Link - Location in Mozilla works as well.)

5.7.6. Going to Bonsai and LXR

To go to Bonsai to get blame for the lines you are interested in, - you can click the "Lines XX-YY" link on the section header you are - interested in. This works even if the patch is against an old - version of the file, since Bonsai stores all versions of the file.

To go to LXR, you click on the filename on the file header - (unfortunately, since LXR only does the most recent version, line - numbers are likely to rot).

5.7.7. Creating a Unified Diff

If the patch is not in a format that you like, you can turn it - into a unified diff format by clicking the "Raw Unified" link at the top - of the page.

5.8. Hints and Tips

This section distills some Bugzilla tips and best practices - that have been developed.

5.8.1. Autolinkification

Bugzilla comments are plain text - so typing <U> will - produce less-than, U, greater-than rather than underlined text. - However, Bugzilla will automatically make hyperlinks out of certain - sorts of text in comments. For example, the text - "http://www.bugzilla.org" will be turned into a link: - http://www.bugzilla.org. - Other strings which get linkified in the obvious manner are: -

bug 12345
comment 7
bug 23456, comment 53
attachment 4321
mailto:george@example.com
george@example.com
ftp://ftp.mozilla.org
Most other sorts of URL

-

A corollary here is that if you type a bug number in a comment, - you should put the word "bug" before it, so it gets autolinkified - for the convenience of others. -

5.8.2. Quicksearch

Quicksearch is a single-text-box query tool which uses - metacharacters to indicate what is to be searched. For example, typing - "foo|bar" - into Quicksearch would search for "foo" or "bar" in the - summary and status whiteboard of a bug; adding - ":BazProduct" would - search only in that product. -

You'll find the Quicksearch box on Bugzilla's - front page, along with a - Help - link which details how to use it.

5.8.3. Comments

If you are changing the fields on a bug, only comment if - either you have something pertinent to say, or Bugzilla requires it. - Otherwise, you may spam people unnecessarily with bug mail. - To take an example: a user can set up their account to filter out messages - where someone just adds themselves to the CC field of a bug - (which happens a lot.) If you come along, add yourself to the CC field, - and add a comment saying "Adding self to CC", then that person - gets a pointless piece of mail they would otherwise have avoided. -

Don't use sigs in comments. Signing your name ("Bill") is acceptable, - if you do it out of habit, but full mail/news-style - four line ASCII art creations are not. -

5.8.4. Attachments

Use attachments, rather than comments, for large chunks of ASCII data, - such as trace, debugging output files, or log files. That way, it doesn't - bloat the bug for everyone who wants to read it, and cause people to - receive fat, useless mails. -

Trim screenshots. There's no need to show the whole screen if - you are pointing out a single-pixel problem. -

Don't attach simple test cases (e.g. one HTML file, one - CSS file and an image) as a ZIP file. Instead, upload them in - reverse order and edit the referring file so that they point to the - attached files. This way, the test case works immediately - out of the bug. -

5.9. User Preferences

Once you have logged in, you can customise various aspects of - Bugzilla via the "Edit prefs" link in the page footer. - The preferences are split into three tabs:

5.9.1. Account Settings

On this tab, you can change your basic account information, - including your password, email address and real name. For security - reasons, in order to change anything on this page you must type your - current - password into the - "Password" - field at the top of the page. - If you attempt to change your email address, a confirmation - email is sent to both the old and new addresses, with a link to use to - confirm the change. This helps to prevent account hijacking.

5.9.2. Email Settings

On this tab you can reduce or increase the amount of email sent - you from Bugzilla, opting in our out depending on your relationship to - the bug and the change that was made to it. -

You can also do further filtering on the client side by - using the X-Bugzilla-Reason mail header which Bugzilla - adds to all bugmail. This tells you what relationship you have to the - bug in question, - and can be any of Owner, Reporter, QAcontact, CClist, Voter and - WatchingComponent.

By entering user email names, delineated by commas, into the - "Users to watch" text entry box you can receive a copy of all the - bugmail of other users (security settings permitting.) This powerful - functionality enables seamless transitions as developers change - projects or users go on holiday.

The ability to watch other users may not be available in all - Bugzilla installations. If you can't see it, ask your - administrator.

5.9.3. Permissions

This is a purely informative page which outlines your current - permissions on this installation of Bugzilla - what product groups you - are in, and whether you can edit bugs or perform various administration - functions.

1. General Questions

A.1.1. - What license is Bugzilla distributed under? -

- Bugzilla is covered by the Mozilla Public License. - See details at http://www.mozilla.org/MPL/. -

A.1.2. - How do I get commercial support for Bugzilla? -

- http://bugzilla.org/consulting.html - is a list of people and companies who have asked us to list them - as consultants for Bugzilla. -

There are several experienced - Bugzilla hackers on the mailing list/newsgroup who are willing - to make themselves available for generous compensation. - Try sending a message to the mailing list asking for a volunteer. -

A.1.3. - What major companies or projects are currently using Bugzilla - for bug-tracking? -

- There are dozens of major companies with public - Bugzilla sites to track bugs in their products. We have a fairly - complete list available on our website at - http://bugzilla.org/installation-list/. If you - have an installation of Bugzilla and would like to be added to the - list, whether it's a public install or not, simply e-mail - Gerv <gerv@mozilla.org>. -

A.1.4. - Who maintains Bugzilla? -

- A - core team, - led by Dave Miller (justdave@bugzilla.org). -

A.1.5. - How does Bugzilla stack up against other bug-tracking databases? -

- We can't find any head-to-head comparisons of Bugzilla against - other defect-tracking software. If you know of one, please - get in touch. However, from the author's personal - experience with other bug-trackers, Bugzilla offers - superior performance on commodity hardware, better price - (free!), more developer- friendly features (such as stored - queries, email integration, and platform independence), - improved scalability, open source code, greater - flexibility, and superior ease-of-use. -

If you happen to be a commercial bug-tracker vendor, please - step forward with a list of advantages your product has over - Bugzilla. We'd be happy to include it in the "Competitors" - section. -

A.1.6. - Why doesn't Bugzilla offer this or that feature or compatibility - with this other tracking software? -

- It may be that the support has not been built yet, or that you - have not yet found it. Bugzilla is making tremendous strides in - usability, customizability, scalability, and user interface. It - is widely considered the most complete and popular open-source - bug-tracking software in existence. -

That doesn't mean it can't use improvement! - You can help the project along by either hacking a patch yourself - that supports the functionality you require, or else submitting a - "Request for Enhancement" (RFE) using the bug submission interface - at bugzilla.mozilla.org. -

A.1.7. - Why MySQL? I'm interested in seeing Bugzilla run on - Oracle/Sybase/Msql/PostgreSQL/MSSQL. -

- MySQL was originally chosen because it is free, easy to install, - and was available for the hardware Netscape intended to run it on. -

There is currently work in progress to make Bugzilla work on - PostgreSQL and Sybase in the default distribution. You can track - the progress of these initiatives in bug 98304 - and bug 173130 - respectively. -

Once both of these are done, adding support for additional - database servers should be trivial. -

A.1.8. - What is /usr/bonsaitools/bin/perl? -

- Bugzilla used to have the path to perl on the shebang line set to - /usr/bonsaitools/bin/perl because when - Terry first started writing the code for mozilla.org he needed a - version of Perl and other tools that were completely under his - control. This location was abandoned for the 2.18 release in favor - of the more sensible /usr/bin/perl. If you - installed an older verion of Bugzilla and created the symlink we - suggested, you can remove it now (provided that you don't have - anything else, such as Bonsai, using it and you don't intend to - reinstall an older version of Bugzilla). -

A.1.9. - My perl is not located at /usr/bin/perl, is - there an easy way to change it everywhere it needs to be changed? -

- Yes, the following bit of perl magic will change all the shebang - lines. Be sure to change /usr/local/bin/perl - to your path to the perl binary. - 


perl -pi -e 's@#\!/usr/bin/perl@#\!/usr/local/bin/perl@' *cgi *pl
-

A.1.10. - Is there an easy way to change the Bugzilla cookie name? -

- At present, no. -

A.1.11. - Does bugzilla run under mod_perl? -

- At present, no. This is being worked on. -

2. Managerial Questions

A.2.1. - Is Bugzilla web-based, or do you have to have specific software or - a specific operating system on your machine? -

- It is web and e-mail based. -

A.2.2. - Does Bugzilla allow us to define our own priorities and levels? Do we - have complete freedom to change the labels of fields and format of them, and - the choice of acceptable values? -

- Yes. However, modifying some fields, notably those related to bug - progression states, also require adjusting the program logic to - compensate for the change. -

There is no GUI for adding fields to Bugzilla at this - time. You can follow development of this feature in - bug 91037 -

A.2.3. - Does Bugzilla provide any reporting features, metrics, graphs, etc? You - know, the type of stuff that management likes to see. :) -

- Yes. Look at http://bugzilla.mozilla.org/report.cgi - for samples of what Bugzilla can do in reporting and graphing. -

If you can not get the reports you want from the included reporting - scripts, it is possible to hook up a professional reporting package - such as Crystal Reports using ODBC. If you choose to do this, - beware that giving direct access to the database does contain some - security implications. Even if you give read-only access to the - bugs database it will bypass the secure bugs features of Bugzilla. -

A.2.4. - Is there email notification and if so, what do you see when you get an - email? -

- Email notification is user-configurable. By default, the bug id and - summary of the bug report accompany each email notification, along with - a list of the changes made. -

A.2.5. - Do users have to have any particular - type of email application? -

- Bugzilla email is sent in plain text, the most compatible mail format - on the planet. -

If you decide to use the bugzilla_email integration features - to allow Bugzilla to record responses to mail with the associated bug, - you may need to caution your users to set their mailer to "respond - to messages in the format in which they were sent". For security reasons - Bugzilla ignores HTML tags in comments, and if a user sends HTML-based - email into Bugzilla the resulting comment looks downright awful. -

-

A.2.6. - Does Bugzilla allow data to be imported and exported? If I had outsiders - write up a bug report using a MS Word bug template, could that template be - imported into "matching" fields? If I wanted to take the results of a query - and export that data to MS Excel, could I do that? -

- Bugzilla can output buglists as HTML (the default), CSV or RDF. - The link for CSV can be found at the bottom of the buglist in HTML - format. This CSV format can easily be imported into MS Excel or - other spreadsheet applications. -

To use the RDF format of the buglist it is necessary to append a - &ctype=rdf to the URL. RDF - is meant to be machine readable and thus it is assumed that the - URL would be generated programatically so there is no user visible - link to this format. -

Currently the only script included with Bugzilla that can import - data is importxml.pl which is intended to be - used for importing the data generated by the XML ctype of - show_bug.cgi in association with bug moving. - Any other use is left as an exercise for the user. -

There are also scripts included in the contrib/ - directory for using e-mail to import information into Bugzilla, - but these scripts are not currently supported and included for - educational purposes. -

A.2.7. - Has anyone converted Bugzilla to another language to be used in other - countries? Is it localizable? -

- Yes. For more information including available translated templates, - see http://www.bugzilla.org/download.html#localizations. - The admin interfaces are still not included in these translated - templates and is therefore still English only. Also, there may be - issues with the charset not being declared. See bug 126226 - for more information. -

A.2.8. - Can a user create and save reports? Can they do this in Word format? - Excel format? -

- Yes. No. Yes (using the CSV format). -

A.2.9. - Does Bugzilla provide record locking when there is simultaneous access - to the same bug? Does the second person get a notice that the bug is in use - or how are they notified? -

- Bugzilla does not lock records. It provides mid-air collision detection, - and offers the offending user a choice of options to deal with the conflict. -

A.2.10. - Are there any backup features provided? -

- MySQL, the database back-end for Bugzilla, allows hot-backup of data. - You can find strategies for dealing with backup considerations - at http://www.mysql.com/doc/B/a/Backup.html. -

A.2.11. - Can users be on the system while a backup is in progress? -

- Yes. However, commits to the database must wait - until the tables are unlocked. Bugzilla databases are typically - very small, and backups routinely take less than a minute. -

A.2.12. - What type of human resources are needed to be on staff to install and - maintain Bugzilla? Specifically, what type of skills does the person need to - have? I need to find out if we were to go with Bugzilla, what types of - individuals would we need to hire and how much would that cost vs buying an - "out-of-the-box" solution? -

- If Bugzilla is set up correctly from the start, continuing maintenance - needs are minimal and can be done easily using the web interface. -

Commercial Bug-tracking software typically costs somewhere upwards - of $20,000 or more for 5-10 floating licenses. Bugzilla consultation - is available from skilled members of the newsgroup. Simple questions - are answered there and then. -

A.2.13. - What time frame are we looking at if we decide to hire people to install - and maintain the Bugzilla? Is this something that takes hours or weeks to - install and a couple of hours per week to maintain and customize or is this - a multi-week install process, plus a full time job for 1 person, 2 people, - etc? -

- It all depends on your level of commitment. Someone with much Bugzilla - experience can get you up and running in less than a day, and - your Bugzilla install can run untended for years. If your - Bugzilla strategy is critical to your business workflow, hire somebody - with reasonable UNIX or Perl skills to handle your process management and - bug-tracking maintenance & customization. -

A.2.14. - Is there any licensing fee or other fees for using Bugzilla? Any - out-of-pocket cost other than the bodies needed as identified above? -

- No. MySQL asks, if you find their product valuable, that you purchase - a support contract from them that suits your needs. -

3. Bugzilla Security

A.3.1. - How do I completely disable MySQL security if it's giving me problems - (I've followed the instructions in the installation section of this guide)? -

- Run MySQL like this: "mysqld --skip-grant-tables". Please remember this - makes MySQL as secure as taping a $100 to the floor of a football stadium - bathroom for safekeeping. -

A.3.2. - Are there any security problems with Bugzilla? -

- The Bugzilla code has undergone a reasonably complete security audit, - and user-facing CGIs run under Perl's taint mode. However, - it is recommended that you closely examine permissions on your Bugzilla - installation, and follow the recommended security guidelines found - in The Bugzilla Guide. -

4. Bugzilla Email

A.4.1. - I have a user who doesn't want to receive any more email from Bugzilla. - How do I stop it entirely for this user? -

- The user should be able to set - this in user email preferences (uncheck all boxes) or you can add - their email address to the data/nomail file. -

A.4.2. - I'm evaluating/testing Bugzilla, and don't want it to send email to - anyone but me. How do I do it? -

- Edit the "newchangedmail" Param. Replace "To:" with "X-Real-To:", - replace "Cc:" with "X-Real-CC:", and add a "To: <youremailaddress>". -

A.4.3. - I want whineatnews.pl to whine at something other than new and - reopened bugs. How do I do it? -

- Try Klaas Freitag's excellent patch for "whineatassigned" - functionality. You can find it in bug 6679. This - patch is against an older version of Bugzilla, so you must apply - the diffs manually. - -

A.4.4. - How do I set up the email interface to submit/change bugs via email? -

- You can find an updated README.mailif file in the contrib/ directory - of your Bugzilla distribution that walks you through the setup. -

A.4.5. - Email takes FOREVER to reach me from Bugzilla -- it's extremely slow. - What gives? -

- If you are using sendmail, try enabling - sendmailnow in editparams.cgi. - -

If you are using an alternate MTA, - make sure the options given in Bugzilla/BugMail.pm - and any other place where sendmail is called from - are correct for your MTA. You should also ensure that the - sendmailnow param is set to on. -

A.4.6. - How come email from Bugzilla changes never reaches me? -

- Double-check that you have not turned off email in your user preferences. - Confirm that Bugzilla is able to send email by visiting the "Log In" - link of your Bugzilla installation and clicking the "Email me a password" - button after entering your email address. -

If you never receive mail from Bugzilla, chances are you do not have - sendmail in "/usr/lib/sendmail". Ensure sendmail lives in, or is symlinked - to, "/usr/lib/sendmail". -

5. Bugzilla Database

A.5.1. - I've heard Bugzilla can be used with Oracle? -

- Red Hat's old version of Bugzilla (based on 2.8) worked on Oracle, - but it is now so old as to be obsolete, and is totally unsupported. - Red Hat's newer version (based on 2.17.1 and soon to be merged into - the main distribution) runs on PostgreSQL. At this time we know of - no recent ports of Bugzilla to Oracle; to be honest, Bugzilla - doesn't need what Oracle offers. -

A.5.2. - I think my database might be corrupted, or contain invalid entries. What - do I do? -

- Run the "sanity check" utility - (sanitycheck.cgi) from your web browser to see! - If it finishes without errors, you're - probably OK. If it doesn't come back - OK (i.e. any red letters), there are certain things - Bugzilla can recover from and certain things it can't. If - it can't auto-recover, I hope you're familiar with - mysqladmin commands or have installed another way to - manage your database. Sanity Check, although it is a good - basic check on your database integrity, by no means is a - substitute for competent database administration and - avoiding deletion of data. It is not exhaustive, and was - created to do a basic check for the most common problems - in Bugzilla databases. -

A.5.3. - I want to manually edit some entries in my database. How? -

- There is no facility in Bugzilla itself to do this. It's also generally - not a smart thing to do if you don't know exactly what you're doing. - However, if you understand SQL you can use the mysql - command line utility to manually insert, delete and modify table - information. There are also more intuitive GUI clients available. - Personal favorites of the Bugzilla team are phpMyAdmin and MySQL Control - Center. -

A.5.4. - I think I've set up MySQL permissions correctly, but Bugzilla still can't - connect. -

- Try running MySQL from its binary: "mysqld --skip-grant-tables". This - will allow you to completely rule out grant tables as the cause of your - frustration. If this Bugzilla is able to connect at this point then - you need to check that you have granted proper permission to the user - password combo defined in localconfig. -

Running MySQL with this command line option is very insecure and - should only be done when not connected to the external network - as a troubleshooting step. -

A.5.5. - How do I synchronize bug information among multiple different Bugzilla - databases? -

- Well, you can synchronize or you can move bugs. Synchronization will - only work one way -- you can create a read-only copy of the database - at one site, and have it regularly updated at intervals from the main - database. -

MySQL has some synchronization features builtin to the latest releases. - It would be great if someone looked into the possibilities there - and provided a report to the newsgroup on how to effectively - synchronize two Bugzilla installations. -

If you simply need to transfer bugs from one Bugzilla to another, - checkout the "move.pl" script in the Bugzilla distribution. -

6. Bugzilla and Win32

A.6.1. - What is the easiest way to run Bugzilla on Win32 (Win98+/NT/2K)? -

- Remove Windows. Install Linux. Install Bugzilla. - The boss will never know the difference. -

A.6.2. - Is there a "Bundle::Bugzilla" equivalent for Win32? -

- Not currently. Bundle::Bugzilla enormously simplifies Bugzilla - installation on UNIX systems. If someone can volunteer to - create a suitable PPM bundle for Win32, it would be appreciated. -

A.6.3. - CGI's are failing with a "something.cgi is not a valid Windows NT - application" error. Why? -

- Depending on what Web server you are using, you will have to configure - the Web server to treat *.cgi files as CGI scripts. In IIS, you do this by - adding *.cgi to the App Mappings with the <path>\perl.exe %s %s as the - executable. -

Microsoft has some advice on this matter, as well: -

"Set application mappings. In the ISM, map the extension for the script - file(s) to the executable for the script interpreter. For example, you might - map the extension .py to Python.exe, the executable for the Python script - interpreter. Note For the ActiveState Perl script interpreter, the extension - .pl is associated with PerlIS.dll by default. If you want to change the - association of .pl to perl.exe, you need to change the application mapping. - In the mapping, you must add two percent (%) characters to the end of the - pathname for perl.exe, as shown in this example: c:\perl\bin\perl.exe %s %s" -

-

A.6.4. - I'm having trouble with the perl modules for NT not being able to talk to - to the database. -

- Your modules may be outdated or inaccurate. Try: -

  1. Hitting http://www.activestate.com/ActivePerl -

  2. Download ActivePerl -

  3. Go to your prompt -

  4. Type 'ppm' -

  5. PPM> install DBI DBD-mysql GD -

- I reckon TimeDate and Data::Dumper come with the activeperl. You can check - the ActiveState site for packages for installation through PPM. - http://www.activestate.com/Packages/. -

7. Bugzilla Usage

A.7.1. - How do I change my user name (email address) in Bugzilla? -

- New in 2.16 - go to the Account section of the Preferences. You will - be emailed at both addresses for confirmation. -

A.7.2. - The query page is very confusing. Isn't there a simpler way to query? -

- The interface was simplified by a UI designer for 2.16. Further - suggestions for improvement are welcome, but we won't sacrifice power for - simplicity. -

A.7.3. - I'm confused by the behavior of the "accept" button in the Show Bug form. - Why doesn't it assign the bug to me when I accept it? -

- The current behavior is acceptable to bugzilla.mozilla.org and most - users. You have your choice of patches to change this behavior, however. -

Add a "and accept bug" radio button
"Accept" button automatically assigns to you

- Note that these patches are somewhat dated. You will need to apply - them manually. -

A.7.4. - I can't upload anything into the database via the "Create Attachment" - link. What am I doing wrong? -

- The most likely cause is a very old browser or a browser that is - incompatible with file upload via POST. Download the latest Netscape, - Microsoft, or Mozilla browser to handle uploads correctly. -

A.7.5. - How do I change a keyword in Bugzilla, once some bugs are using it? -

- In the Bugzilla administrator UI, edit the keyword and it will let you - replace the old keyword name with a new one. This will cause a problem - with the keyword cache. Run sanitycheck.cgi to fix it. -

A.7.6. - Why can't I close bugs from the "Change Several Bugs at Once" page? -

- The logic flow currently used is RESOLVED, then VERIFIED, then CLOSED. - You can mass-CLOSE bugs from the change several - bugs at once page. but, every bug listed on the - page has to be in VERIFIED state before the control to do it will show - up on the form. You can also mass-VERIFY, but every bug listed has to be - RESOLVED in order for the control to show up on the form. The logic - behind this is that if you pick one of the bugs that's not VERIFIED and - try to CLOSE it, the bug change will fail miserably (thus killing any - changes in the list after it while doing the bulk change) so it doesn't - even give you the choice. -

8. Bugzilla Hacking

A.8.1. - What kind of style should I use for templatization? -

- Gerv and Myk suggest a 2-space indent, with embedded code sections on - their own line, in line with outer tags. Like this:


<fred>
-[% IF foo %]
-  <bar>
-  [% FOREACH x = barney %]
-    <tr>
-      <td>
-        [% x %]
-      </td>
-    <tr>
-  [% END %]
-[% END %]
-</fred>
-

Myk also recommends you turn on PRE_CHOMP in the template - initialization to prevent bloating of HTML with unnecessary whitespace. -

Please note that many have differing opinions on this subject, - and the existing templates in Bugzilla espouse both this and a 4-space - style. Either is acceptable; the above is preferred.

A.8.2. - What bugs are in Bugzilla right now? -

- Try this link to view current bugs or requests for - enhancement for Bugzilla. -

You can view bugs marked for 2.18 release - here. - This list includes bugs for the 2.18 release that have already - been fixed and checked into CVS. Please consult the - Bugzilla Project Page for details on how to - check current sources out of CVS so you can have these - bug fixes early! -

A.8.3. - How can I change the default priority to a null value? For instance, have the default - priority be "---" instead of "P2"? -

- This is well-documented in bug 49862. Ultimately, it's as easy as adding the "---" priority field to your - localconfig file in the appropriate area, re-running checksetup.pl, and then changing the - default priority in your browser using "editparams.cgi". -

A.8.4. - What's the best way to submit patches? What guidelines should I follow? -

  1. Enter a bug into bugzilla.mozilla.org for the "Bugzilla" - product. -

  2. Upload your patch as a unified diff (having used "diff -u" against - the current sources checked out of CVS), - or new source file by clicking - "Create a new attachment" link on the bug page you've just created, and - include any descriptions of database changes you may make, into the bug - ID you submitted in step #1. Be sure and click the "Patch" checkbox - to indicate the text you are sending is a patch! -

  3. Announce your patch and the associated URL - (http://bugzilla.mozilla.org/show_bug.cgi?id=XXXXXX) for discussion in - the newsgroup (netscape.public.mozilla.webtools). You'll get a really - good, fairly immediate reaction to the implications of your patch, - which will also give us an idea how well-received the change would - be. -

  4. If it passes muster with minimal modification, the person to whom - the bug is assigned in Bugzilla is responsible for seeing the patch - is checked into CVS. -

  5. Bask in the glory of the fact that you helped write the most successful - open-source bug-tracking software on the planet :) -

Appendix B. Contrib

There are a number of unofficial Bugzilla add-ons in the - $BUGZILLA_ROOT/contrib/ - directory. This section documents them.

B.1. Command-line Search Interface

There are a suite of Unix utilities for searching Bugzilla from the - command line. They live in the - contrib/cmdline - directory. However, they - have not yet been updated to work with 2.16 (post-templatisation.). - There are three files - query.conf, - buglist and bugs.

query.conf - contains the mapping from options to field - names and comparison types. Quoted option names are "grepped" for, so it - should be easy to edit this file. Comments (#) have no effect; you must - make sure these lines do not contain any quoted "option".

buglist - is a shell script which submits a Bugzilla query and writes - the resulting HTML page to stdout. It supports both short options, (such - as "-Afoo" or "-Rbar") and long options (such as "--assignedto=foo" or - "--reporter=bar"). If the first character of an option is not "-", it is - treated as if it were prefixed with "--default=".

The column list is taken from the COLUMNLIST environment variable. - This is equivalent to the "Change Columns" option when you list bugs in - buglist.cgi. If you have already used Bugzilla, grep for COLUMNLIST - in your cookies file to see your current COLUMNLIST setting.

bugs is a simple shell script which calls - buglist and extracts the - bug numbers from the output. Adding the prefix - "http://bugzilla.mozilla.org/buglist.cgi?bug_id=" turns the bug list into - a working link if any bugs are found. Counting bugs is easy. Pipe the - results through - sed -e 's/,/ /g' | wc | awk '{printf $2 "\n"}' -

Akkana Peck says she has good results piping - buglist output through - w3m -T text/html -dump -

Appendix C. Manual Installation of Perl Modules

Appendix D. GNU Free Documentation License

Version 1.1, March 2000

Copyright (C) 2000 Free Software Foundation, Inc. 59 Temple Place, - Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and - distribute verbatim copies of this license document, but changing it is - not allowed.

0. Preamble

The purpose of this License is to make a manual, textbook, or other - written document "free" in the sense of freedom: to assure everyone the - effective freedom to copy and redistribute it, with or without modifying - it, either commercially or noncommercially. Secondarily, this License - preserves for the author and publisher a way to get credit for their - work, while not being considered responsible for modifications made by - others.

This License is a kind of "copyleft", which means that derivative - works of the document must themselves be free in the same sense. It - complements the GNU General Public License, which is a copyleft license - designed for free software.

We have designed this License in order to use it for manuals for - free software, because free software needs free documentation: a free - program should come with manuals providing the same freedoms that the - software does. But this License is not limited to software manuals; it - can be used for any textual work, regardless of subject matter or whether - it is published as a printed book. We recommend this License principally - for works whose purpose is instruction or reference.

1. Applicability and Definition

This License applies to any manual or other work that contains a - notice placed by the copyright holder saying it can be distributed under - the terms of this License. The "Document", below, refers to any such - manual or work. Any member of the public is a licensee, and is addressed - as "you".

A "Modified Version" of the Document means any work containing the - Document or a portion of it, either copied verbatim, or with - modifications and/or translated into another language.

A "Secondary Section" is a named appendix or a front-matter section - of the Document that deals exclusively with the relationship of the - publishers or authors of the Document to the Document's overall subject - (or to related matters) and contains nothing that could fall directly - within that overall subject. (For example, if the Document is in part a - textbook of mathematics, a Secondary Section may not explain any - mathematics.) The relationship could be a matter of historical connection - with the subject or with related matters, or of legal, commercial, - philosophical, ethical or political position regarding them.

The "Invariant Sections" are certain Secondary Sections whose - titles are designated, as being those of Invariant Sections, in the - notice that says that the Document is released under this License.

The "Cover Texts" are certain short passages of text that are - listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says - that the Document is released under this License.

A "Transparent" copy of the Document means a machine-readable copy, - represented in a format whose specification is available to the general - public, whose contents can be viewed and edited directly and - straightforwardly with generic text editors or (for images composed of - pixels) generic paint programs or (for drawings) some widely available - drawing editor, and that is suitable for input to text formatters or for - automatic translation to a variety of formats suitable for input to text - formatters. A copy made in an otherwise Transparent file format whose - markup has been designed to thwart or discourage subsequent modification - by readers is not Transparent. A copy that is not "Transparent" is called - "Opaque".

Examples of suitable formats for Transparent copies include plain - ASCII without markup, Texinfo input format, LaTeX input format, SGML or - XML using a publicly available DTD, and standard-conforming simple HTML - designed for human modification. Opaque formats include PostScript, PDF, - proprietary formats that can be read and edited only by proprietary word - processors, SGML or XML for which the DTD and/or processing tools are not - generally available, and the machine-generated HTML produced by some word - processors for output purposes only.

The "Title Page" means, for a printed book, the title page itself, - plus such following pages as are needed to hold, legibly, the material - this License requires to appear in the title page. For works in formats - which do not have any title page as such, "Title Page" means the text - near the most prominent appearance of the work's title, preceding the - beginning of the body of the text.

2. Verbatim Copying

You may copy and distribute the Document in any medium, either - commercially or noncommercially, provided that this License, the - copyright notices, and the license notice saying this License applies to - the Document are reproduced in all copies, and that you add no other - conditions whatsoever to those of this License. You may not use technical - measures to obstruct or control the reading or further copying of the - copies you make or distribute. However, you may accept compensation in - exchange for copies. If you distribute a large enough number of copies - you must also follow the conditions in section 3.

You may also lend copies, under the same conditions stated above, - and you may publicly display copies.

3. Copying in Quantity

If you publish printed copies of the Document numbering more than - 100, and the Document's license notice requires Cover Texts, you must - enclose the copies in covers that carry, clearly and legibly, all these - Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts - on the back cover. Both covers must also clearly and legibly identify you - as the publisher of these copies. The front cover must present the full - title with all words of the title equally prominent and visible. You may - add other material on the covers in addition. Copying with changes - limited to the covers, as long as they preserve the title of the Document - and satisfy these conditions, can be treated as verbatim copying in other - respects.

If the required texts for either cover are too voluminous to fit - legibly, you should put the first ones listed (as many as fit reasonably) - on the actual cover, and continue the rest onto adjacent pages.

If you publish or distribute Opaque copies of the Document - numbering more than 100, you must either include a machine-readable - Transparent copy along with each Opaque copy, or state in or with each - Opaque copy a publicly-accessible computer-network location containing a - complete Transparent copy of the Document, free of added material, which - the general network-using public has access to download anonymously at no - charge using public-standard network protocols. If you use the latter - option, you must take reasonably prudent steps, when you begin - distribution of Opaque copies in quantity, to ensure that this - Transparent copy will remain thus accessible at the stated location until - at least one year after the last time you distribute an Opaque copy - (directly or through your agents or retailers) of that edition to the - public.

It is requested, but not required, that you contact the authors of - the Document well before redistributing any large number of copies, to - give them a chance to provide you with an updated version of the - Document.

4. Modifications

You may copy and distribute a Modified Version of the Document - under the conditions of sections 2 and 3 above, provided that you release - the Modified Version under precisely this License, with the Modified - Version filling the role of the Document, thus licensing distribution and - modification of the Modified Version to whoever possesses a copy of it. - In addition, you must do these things in the Modified Version:

  1. Use in the Title Page (and on the covers, if any) a title - distinct from that of the Document, and from those of previous - versions (which should, if there were any, be listed in the History - section of the Document). You may use the same title as a previous - version if the original publisher of that version gives - permission.

  2. List on the Title Page, as authors, one or more persons or - entities responsible for authorship of the modifications in the - Modified Version, together with at least five of the principal - authors of the Document (all of its principal authors, if it has less - than five).

  3. State on the Title page the name of the publisher of the - Modified Version, as the publisher.

  4. Preserve all the copyright notices of the Document.

  5. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices.

  6. Include, immediately after the copyright notices, a license - notice giving the public permission to use the Modified Version under - the terms of this License, in the form shown in the Addendum - below.

  7. Preserve in that license notice the full lists of Invariant - Sections and required Cover Texts given in the Document's license - notice.

  8. Include an unaltered copy of this License.

  9. Preserve the section entitled "History", and its title, and add - to it an item stating at least the title, year, new authors, and - publisher of the Modified Version as given on the Title Page. If - there is no section entitled "History" in the Document, create one - stating the title, year, authors, and publisher of the Document as - given on its Title Page, then add an item describing the Modified - Version as stated in the previous sentence.

  10. Preserve the network location, if any, given in the Document - for public access to a Transparent copy of the Document, and likewise - the network locations given in the Document for previous versions it - was based on. These may be placed in the "History" section. You may - omit a network location for a work that was published at least four - years before the Document itself, or if the original publisher of the - version it refers to gives permission.

  11. In any section entitled "Acknowledgements" or "Dedications", - preserve the section's title, and preserve in the section all the - substance and tone of each of the contributor acknowledgements and/or - dedications given therein.

  12. Preserve all the Invariant Sections of the Document, unaltered - in their text and in their titles. Section numbers or the equivalent - are not considered part of the section titles.

  13. Delete any section entitled "Endorsements". Such a section may - not be included in the Modified Version.

  14. Do not retitle any existing section as "Endorsements" or to - conflict in title with any Invariant Section.

If the Modified Version includes new front-matter sections or - appendices that qualify as Secondary Sections and contain no material - copied from the Document, you may at your option designate some or all of - these sections as invariant. To do this, add their titles to the list of - Invariant Sections in the Modified Version's license notice. These titles - must be distinct from any other section titles.

You may add a section entitled "Endorsements", provided it contains - nothing but endorsements of your Modified Version by various parties--for - example, statements of peer review or that the text has been approved by - an organization as the authoritative definition of a standard.

You may add a passage of up to five words as a Front-Cover Text, - and a passage of up to 25 words as a Back-Cover Text, to the end of the - list of Cover Texts in the Modified Version. Only one passage of - Front-Cover Text and one of Back-Cover Text may be added by (or through - arrangements made by) any one entity. If the Document already includes a - cover text for the same cover, previously added by you or by arrangement - made by the same entity you are acting on behalf of, you may not add - another; but you may replace the old one, on explicit permission from the - previous publisher that added the old one.

The author(s) and publisher(s) of the Document do not by this - License give permission to use their names for publicity for or to assert - or imply endorsement of any Modified Version.

5. Combining Documents

You may combine the Document with other documents released under - this License, under the terms defined in section 4 above for modified - versions, provided that you include in the combination all of the - Invariant Sections of all of the original documents, unmodified, and list - them all as Invariant Sections of your combined work in its license - notice.

The combined work need only contain one copy of this License, and - multiple identical Invariant Sections may be replaced with a single copy. - If there are multiple Invariant Sections with the same name but different - contents, make the title of each such section unique by adding at the end - of it, in parentheses, the name of the original author or publisher of - that section if known, or else a unique number. Make the same adjustment - to the section titles in the list of Invariant Sections in the license - notice of the combined work.

In the combination, you must combine any sections entitled - "History" in the various original documents, forming one section entitled - "History"; likewise combine any sections entitled "Acknowledgements", and - any sections entitled "Dedications". You must delete all sections - entitled "Endorsements."

6. Collections of Documents

You may make a collection consisting of the Document and other - documents released under this License, and replace the individual copies - of this License in the various documents with a single copy that is - included in the collection, provided that you follow the rules of this - License for verbatim copying of each of the documents in all other - respects.

You may extract a single document from such a collection, and - distribute it individually under this License, provided you insert a copy - of this License into the extracted document, and follow this License in - all other respects regarding verbatim copying of that document.

7. Aggregation with Independent Works

A compilation of the Document or its derivatives with other - separate and independent documents or works, in or on a volume of a - storage or distribution medium, does not as a whole count as a Modified - Version of the Document, provided no compilation copyright is claimed for - the compilation. Such a compilation is called an "aggregate", and this - License does not apply to the other self-contained works thus compiled - with the Document, on account of their being thus compiled, if they are - not themselves derivative works of the Document.

If the Cover Text requirement of section 3 is applicable to these - copies of the Document, then if the Document is less than one quarter of - the entire aggregate, the Document's Cover Texts may be placed on covers - that surround only the Document within the aggregate. Otherwise they must - appear on covers around the whole aggregate.

8. Translation

Translation is considered a kind of modification, so you may - distribute translations of the Document under the terms of section 4. - Replacing Invariant Sections with translations requires special - permission from their copyright holders, but you may include translations - of some or all Invariant Sections in addition to the original versions of - these Invariant Sections. You may include a translation of this License - provided that you also include the original English version of this - License. In case of a disagreement between the translation and the - original English version of this License, the original English version - will prevail.

9. Termination

You may not copy, modify, sublicense, or distribute the Document - except as expressly provided for under this License. Any other attempt to - copy, modify, sublicense or distribute the Document is void, and will - automatically terminate your rights under this License. However, parties - who have received copies, or rights, from you under this License will not - have their licenses terminated so long as such parties remain in full - compliance.

10. Future Revisions of this License

The Free Software Foundation may publish new, revised versions of - the GNU Free Documentation License from time to time. Such new versions - will be similar in spirit to the present version, but may differ in - detail to address new problems or concerns. See - http://www.gnu.org/copyleft/.

Each version of the License is given a distinguishing version - number. If the Document specifies that a particular numbered version of - this License "or any later version" applies to it, you have the option of - following the terms and conditions either of that specified version or of - any later version that has been published (not as a draft) by the Free - Software Foundation. If the Document does not specify a version number of - this License, you may choose any version ever published (not as a draft) - by the Free Software Foundation.

How to use this License for your documents

To use this License in a document you have written, include a copy - of the License in the document and put the following copyright and - license notices just after the title page:

Copyright (c) YEAR YOUR NAME. Permission is granted to copy, - distribute and/or modify this document under the terms of the GNU Free - Documentation License, Version 1.1 or any later version published by - the Free Software Foundation; with the Invariant Sections being LIST - THEIR TITLES, with the Front-Cover Texts being LIST, and with the - Back-Cover Texts being LIST. A copy of the license is included in the - section entitled "GNU Free Documentation License".

If you have no Invariant Sections, write "with no Invariant - Sections" instead of saying which ones are invariant. If you have no - Front-Cover Texts, write "no Front-Cover Texts" instead of "Front-Cover - Texts being LIST"; likewise for Back-Cover Texts.

If your document contains nontrivial examples of program code, we - recommend releasing these examples in parallel under your choice of free - software license, such as the GNU General Public License, to permit their - use in free software.

.htaccess

Apache web server, and other NCSA-compliant web servers, - observe the convention of using files in directories called - .htaccess - - to restrict access to certain files. In Bugzilla, they are used - to keep secret files which would otherwise - compromise your installation - e.g. the - localconfig - file contains the password to your database. - curious.

A

Apache

In this context, Apache is the web server most commonly used - for serving up Bugzilla - pages. Contrary to popular belief, the apache web server has nothing - to do with the ancient and noble Native American tribe, but instead - derived its name from the fact that it was - "a patchy" - version of the original - NCSA - world-wide-web server.

Useful Directives when configuring Bugzilla

AddHandler

Tell Apache that it's OK to run CGI scripts.

AllowOverride, Options

These directives are used to tell Apache many things about - the directory they apply to. For Bugzilla's purposes, we need - them to allow script execution and .htaccess - overrides. -

DirectoryIndex

Used to tell Apache what files are indexes. If you can - not add index.cgi to the list of valid files, - you'll need to set $index_html to - 1 in localconfig so - ./checksetup.pl will create an - index.html that redirects to - index.cgi. -

ScriptInterpreterSource

Used when running Apache on windows so the shebang line - doesn't have to be changed in every Bugzilla script. -

For more information about how to configure Apache for Bugzilla, - see Section 2.2.4.1. -

B

Bug

A - "bug" - - in Bugzilla refers to an issue entered into the database which has an - associated number, assignments, comments, etc. Some also refer to a - "tickets" - or - "issues"; - in the context of Bugzilla, they are synonymous.

Bug Number

Each Bugzilla bug is assigned a number that uniquely identifies - that bug. The bug associated with a bug number can be pulled up via a - query, or easily from the very front page by typing the number in the - "Find" box.

Bugzilla

Bugzilla is the world-leading free software bug tracking system. -

C

Common Gateway Interface
(CGI)

CGI is an acronym for Common Gateway Interface. This is - a standard for interfacing an external application with a web server. Bugzilla - is an example of a CGI application. -

Component

A Component is a subsection of a Product. It should be a narrow - category, tailored to your organization. All Products must contain at - least one Component (and, as a matter of fact, creating a Product - with no Components will create an error in Bugzilla).

Comprehensive Perl Archive Network
(CPAN)

CPAN - - stands for the - "Comprehensive Perl Archive Network". - CPAN maintains a large number of extremely useful - Perl - modules - encapsulated chunks of code for performing a - particular task.

contrib

The contrib directory is - a location to put scripts that have been contributed to Bugzilla but - are not a part of the official distribution. These scripts are written - by third parties and may be in languages other than perl. For those - that are in perl, there may be additional modules or other requirements - than those of the offical distribution. -

Scripts in the contrib - directory are not offically supported by the Bugzilla team and may - break in between versions. -

-

D

daemon

A daemon is a computer program which runs in the background. In - general, most daemons are started at boot time via System V init - scripts, or through RC scripts on BSD-based systems. - mysqld, - the MySQL server, and - apache, - a web server, are generally run as daemons.

G

Groups

The word - "Groups" - - has a very special meaning to Bugzilla. Bugzilla's main security - mechanism comes by placing users in groups, and assigning those - groups certain privileges to view bugs in particular - Products - in the - Bugzilla - database.

J

JavaScript

JavaScript is cool, we should talk about it. -

M

Message Transport Agent
(MTA)

A Message Transport Agent is used to control the flow of email - on a system. Many unix based systems use - sendmail which is what - Bugzilla expects to find by default at /usr/sbin/sendmail. - Many other MTA's will work, but they all require that the - sendmailnow param be set to on. -

MySQL

MySQL is currently the required - RDBMS for Bugzilla. MySQL - can be downloaded from http://www.mysql.com. While you - should familiarize yourself with all of the documentation, some high - points are: -

Backup

Methods for backing up your Bugzilla database. -

Option Files

Information about how to configure MySQL using - my.cnf. -

Privilege System

Much more detailed information about the suggestions in - Section 2.2.2.1. -

P

Perl Package Manager
(PPM)

http://aspn.activestate.com/ASPN/Downloads/ActivePerl/PPM/ -

Product

A Product is a broad category of types of bugs, normally - representing a single piece of software or entity. In general, - there are several Components to a Product. A Product may define a - group (used for security) for all bugs entered into - its Components.

Perl

First written by Larry Wall, Perl is a remarkable program - language. It has the benefits of the flexibility of an interpreted - scripting language (such as shell script), combined with the speed - and power of a compiled language, such as C. - Bugzilla - - is maintained in Perl.

Q

QA

"QA", - "Q/A", and - "Q.A." - are short for - "Quality Assurance". - In most large software development organizations, there is a team - devoted to ensuring the product meets minimum standards before - shipping. This team will also generally want to track the progress of - bugs over their life cycle, thus the need for the - "QA Contact" - - field in a bug.

R

Relational DataBase Managment System
(RDBMS)

A relational database management system is a database system - that stores information in tables that are related to each other. -

Regular Expression
(regexp)

A regular expression is an expression used for pattern matching. - Documentation -

S

SGML -

SGML - - stands for - "Standard Generalized Markup Language". - Created in the 1980's to provide an extensible means to maintain - documentation based upon content instead of presentation, - SGML - - has withstood the test of time as a robust, powerful language. - XML - - - is the - "baby brother" - - of SGML; any valid - XML - - document it, by definition, a valid - SGML - - document. The document you are reading is written and maintained in - SGML, - and is also valid - XML - - if you modify the Document Type Definition.

T

Target Milestone

Target Milestones are Product goals. They are configurable on a - per-Product basis. Most software development houses have a concept of - - "milestones" - - where the people funding a project expect certain functionality on - certain dates. Bugzilla facilitates meeting these milestones by - giving you the ability to declare by which milestone a bug will be - fixed, or an enhancement will be implemented.

Tool Command Language
(TCL)

TCL is an open source scripting language available for Windows, - Macintosh, and Unix based systems. Bugzilla 1.0 was written in TCL but - never released. The first release of Bugzilla was 2.0, which was when - it was ported to perl. -

Z

Zarro Boogs Found

This is just a goofy way of saying that there were no bugs - found matching your query. When asked to explain this message, - Terry had the following to say: -

 

I've been asked to explain this ... way back when, when - Netscape released version 4.0 of its browser, we had a release - party. Naturally, there had been a big push to try and fix every - known bug before the release. Naturally, that hadn't actually - happened. (This is not unique to Netscape or to 4.0; the same thing - has happened with every software project I've ever seen.) Anyway, - at the release party, T-shirts were handed out that said something - like "Netscape 4.0: Zarro Boogs". Just like the software, the - T-shirt had no known bugs. Uh-huh. -

So, when you query for a list of bugs, and it gets no results, - you can think of this as a friendly reminder. Of *course* there are - bugs matching your query, they just aren't in the bugsystem yet... -

5.3. Anatomy of a Bug

The core of Bugzilla is the screen which displays a particular - bug. It's a good place to explain some Bugzilla concepts. - Bug 1 on Landfill - - is a good example. Note that the labels for most fields are hyperlinks; - clicking them will take you to context-sensitive help on that - particular field. Fields marked * may not be present on every - installation of Bugzilla.

  1. Product and Component: - Bugs are divided up by Product and Component, with a Product - having one or more Components in it. For example, - bugzilla.mozilla.org's "Bugzilla" Product is composed of several - Components: -

    Administration: - Administration of a Bugzilla installation.
    Bugzilla-General: - Anything that doesn't fit in the other components, or spans - multiple components.
    Creating/Changing Bugs: - Creating, changing, and viewing bugs.
    Documentation: - The Bugzilla documentation, including The Bugzilla Guide.
    Email: - Anything to do with email sent by Bugzilla.
    Installation: - The installation process of Bugzilla.
    Query/Buglist: - Anything to do with searching for bugs and viewing the - buglists.
    Reporting/Charting: - Getting reports from Bugzilla.
    User Accounts: - Anything about managing a user account from the user's perspective. - Saved queries, creating accounts, changing passwords, logging in, - etc.
    User Interface: - General issues having to do with the user interface cosmetics (not - functionality) including cosmetic issues, HTML templates, - etc.

    -

  2. Status and Resolution: - - These define exactly what state the bug is in - from not even - being confirmed as a bug, through to being fixed and the fix - confirmed by Quality Assurance. The different possible values for - Status and Resolution on your installation should be documented in the - context-sensitive help for those items.

  3. Assigned To: - The person responsible for fixing the bug.

  4. *URL: - A URL associated with the bug, if any.

  5. Summary: - A one-sentence summary of the problem.

  6. *Status Whiteboard: - (a.k.a. Whiteboard) A free-form text area for adding short notes - and tags to a bug.

  7. *Keywords: - The administrator can define keywords which you can use to tag and - categorise bugs - e.g. The Mozilla Project has keywords like crash - and regression.

  8. Platform and OS: - These indicate the computing environment where the bug was - found.

  9. Version: - The "Version" field is usually used for versions of a product which - have been released, and is set to indicate which versions of a - Component have the particular problem the bug report is - about.

  10. Priority: - The bug assignee uses this field to prioritise his or her bugs. - It's a good idea not to change this on other people's bugs.

  11. Severity: - This indicates how severe the problem is - from blocker - ("application unusable") to trivial ("minor cosmetic issue"). You - can also use this field to indicate whether a bug is an enhancement - request.

  12. *Target: - (a.k.a. Target Milestone) A future version by which the bug is to - be fixed. e.g. The Bugzilla Project's milestones for future - Bugzilla versions are 2.18, 2.20, 3.0, etc. Milestones are not - restricted to numbers, thought - you can use any text strings, such - as dates.

  13. Reporter: - The person who filed the bug.

  14. CC list: - A list of people who get mail when the bug changes.

  15. Attachments: - You can attach files (e.g. testcases or patches) to bugs. If there - are any attachments, they are listed in this section.

  16. *Dependencies: - If this bug cannot be fixed unless other bugs are fixed (depends - on), or this bug stops other bugs being fixed (blocks), their - numbers are recorded here.

  17. *Votes: - Whether this bug has any votes.

  18. Additional Comments: - You can add your two cents to the bug discussion here, if you have - something worthwhile to say.

5.6. Filing Bugs

Years of bug writing experience has been distilled for your - reading pleasure into the - Bug Writing Guidelines. - While some of the advice is Mozilla-specific, the basic principles of - reporting Reproducible, Specific bugs, isolating the Product you are - using, the Version of the Product, the Component which failed, the - Hardware Platform, and Operating System you were using at the time of - the failure go a long way toward ensuring accurate, responsible fixes - for the bug that bit you.

The procedure for filing a test bug is as follows:

  1. Go to - Landfill - in your browser and click - Enter a new bug report. -

  2. Select a product - any one will do.

  3. Fill in the fields. Bugzilla should have made reasonable - guesses, based upon your browser, for the "Platform" and "OS" - drop-down boxes. If they are wrong, change them.

  4. Select "Commit" and send in your bug report.

Try to make sure that everything said in the summary is also - said in the first comment. Summaries are often updated and this will - ensure your original information is easily accessible. -

You do not need to put "any" or similar strings in the URL field. - If there is no specific URL associated with the bug, leave this - field blank. -

If you feel a bug you filed was incorrectly marked as a - DUPLICATE of another, please question it in your bug, not - the bug it was duped to. Feel free to CC the person who duped it - if they are not already CCed. -

B.1. Command-line Search Interface

There are a suite of Unix utilities for searching Bugzilla from the - command line. They live in the - contrib/cmdline - directory. However, they - have not yet been updated to work with 2.16 (post-templatisation.). - There are three files - query.conf, - buglist and bugs.

query.conf - contains the mapping from options to field - names and comparison types. Quoted option names are "grepped" for, so it - should be easy to edit this file. Comments (#) have no effect; you must - make sure these lines do not contain any quoted "option".

buglist - is a shell script which submits a Bugzilla query and writes - the resulting HTML page to stdout. It supports both short options, (such - as "-Afoo" or "-Rbar") and long options (such as "--assignedto=foo" or - "--reporter=bar"). If the first character of an option is not "-", it is - treated as if it were prefixed with "--default=".

The column list is taken from the COLUMNLIST environment variable. - This is equivalent to the "Change Columns" option when you list bugs in - buglist.cgi. If you have already used Bugzilla, grep for COLUMNLIST - in your cookies file to see your current COLUMNLIST setting.

bugs is a simple shell script which calls - buglist and extracts the - bug numbers from the output. Adding the prefix - "http://bugzilla.mozilla.org/buglist.cgi?bug_id=" turns the bug list into - a working link if any bugs are found. Counting bugs is easy.

3.4. Components

Components are subsections of a Product. E.g. the computer game - you are designing may have a "UI" - component, an "API" component, a "Sound System" component, and a - "Plugins" component, each overseen by a different programmer. It - often makes sense to divide Components in Bugzilla according to the - natural divisions of responsibility within your Product or - company.

Each component has a owner and (if you turned it on in the parameters), - a QA Contact. The owner should be the primary person who fixes bugs in - that component. The QA Contact should be the person who will ensure - these bugs are completely fixed. The Owner, QA Contact, and Reporter - will get email when new bugs are created in this Component and when - these bugs change. Default Owner and Default QA Contact fields only - dictate the - default assignments; - these can be changed on bug submission, or at any later point in - a bug's life.

To create a new Component:

  1. Select the "Edit components" link from the "Edit product" - page

  2. Select the "Add" link in the bottom right.

  3. Fill out the "Component" field, a short "Description", - the "Initial Owner" and "Initial QA Contact" (if enabled.) - The Component and Description fields may contain HTML; - the "Initial Owner" field must be a login name - already existing in the database. -

The Bugzilla Guide - 2.17.7 - Development Release
PrevChapter 2. Installing BugzillaNext

2.2. Configuration

Poorly-configured MySQL and Bugzilla installations have - given attackers full access to systems in the past. Please take the - security parts of these guidelines seriously, even for Bugzilla - machines hidden away behind your firewall.

2.2.1. localconfig

Once you run checksetup.pl with all the correct - modules installed, it displays a message about, and write out a - file called, - localconfig. This file contains the default - settings for a number of Bugzilla parameters. -

Load this file in your editor. The only value you - need to change is $db_pass, the password for - the user you will create for your database. - Pick a strong password (for simplicity, it should not contain - single quote characters) and put it here. -

The other options in the localconfig file - are documented by their accompanying comments. If you have a slightly - non-standard MySQL setup, you may wish to change one or more of - the other "$db_*" parameters. -

You may also wish to change the names of - the priorities, severities, operating systems and platforms for your - installation. However, you can always change these after installation - has finished; if you then re-run - checksetup.pl, the changes will get picked up. -

2.2.2. MySQL

2.2.2.1. Security

MySQL ships as insecure by default. - It allows anybody to on the local machine full administrative - capabilities without requiring a password; the special - MySQL root account (note: this is not the same as - the system root) also has no password. - Also, many installations default to running - mysqld as the system root. -

  1. To disable the anonymous user account - and set a password for the root user, execute the following. The - root user password should be different to the bugs user password - you set in - localconfig in the previous section, - and also different to - the password for the system root account on your machine. - 

      bash$ mysql mysql
-  mysql> DELETE FROM user WHERE user = '';
-  mysql> UPDATE user SET password = password('new_password') WHERE user = 'root';
-  mysql> FLUSH PRIVILEGES;

    From this point forward, to run the - mysql command-line client, - you will need to type - mysql -u root -p and enter - new_password when prompted. -

  2. If you run MySQL on the same machine as your web server, you - should disable remote access to MySQL by adding - the following to your /etc/my.conf: - 

      [myslqd]
-  # Prevent network access to MySQL.
-  skip-networking

  3. Consult the documentation that came with your system for - information on making mysqld run as an - unprivileged user. -

  4. For added security, you could also run MySQL, or even all - of Bugzilla - in a chroot jail; however, instructions for doing that are beyond - the scope of this document. -

2.2.2.2. Allow large attachments

You need to configure MySQL to accept large packets, if you - want to have attachments larger than 64K. Add the text - below to your - /etc/my.conf. - There is also a parameter in Bugzilla - for setting the maximum allowable attachment size, (default 1MB). - Bugzilla will only accept attachments up to the lower of these two - sizes. - 

  [mysqld]
-  # Allow packets up to 1M
-  set-variable = max_allowed_packet=1M

2.2.2.3. Add a user to MySQL

You need to add a new MySQL user for - Bugzilla to use. (It's not safe to have Bugzilla use the MySQL root - account.) The following instructions assume the defaults in - localconfig; - if you changed those, you need to modify the - SQL command appropriately. You will need the - $db_pass password you set in - localconfig in - Section 2.2.1. -

We use an SQL GRANT command to create a - "bugs" - user. This also restricts the - "bugs" - user to operations within a database called - "bugs", and only allows the account to connect from - "localhost". - Modify it to reflect your setup if you will be connecting from - another machine or as a different user.

Run the mysql command-line client and - enter:

  mysql> GRANT SELECT,INSERT,UPDATE,DELETE,INDEX,ALTER,CREATE,
-         DROP,REFERENCES ON bugs.* TO bugs@localhost
-         IDENTIFIED BY '$db_pass';
-  mysql> FLUSH PRIVILEGES

If you are using MySQL 4, you need to add - the LOCK TABLES and - CREATE TEMPORARY TABLES permissions - to the list. -

2.2.3. checksetup.pl

Next, rerun checksetup.pl. It reconfirms - that all the modules are present, and notices the altered - localconfig file, which it assumes you have edited to your - satisfaction. It compiles the UI templates, - connects to the database using the 'bugs' - user you created and the password you defined, and creates the - 'bugs' database and the tables therein. -

After that, it asks for details of an administrator account. Bugzilla - can have multiple administrators - you can create more later - but - it needs one to start off with. - Enter the email address of an administrator, his or her full name, - and a suitable Bugzilla password. -

checksetup.pl will then finish. You may rerun - checksetup.pl at any time if you wish. -

2.2.4. Web server

Configure your web server according to the instructions in the - appropriate section. The Bugzilla Team recommends Apache. -

2.2.4.1. Apache httpd

Load httpd.conf in your editor.

Uncomment (or add) the following line. - This configures Apache to run .cgi files outside the - cgi-bin directory. - 

  AddHandler cgi-script .cgi

Apache uses <Directory> - directives to permit fine-grained permission setting. - Add the following two lines to a - <Directory> directive that - applies either to the Bugzilla directory or one of its parents - (e.g. the <Directory /var/www/html> - directive). - This allows Bugzilla's .htaccess files to - override global permissions, and allows .cgi files to run in the - Bugzilla directory. - 

  Options +ExecCGI +FollowSymLinks
-  AllowOverride Limit

Add index.cgi to the end - of the DirectoryIndex - line.

checksetup.pl can set tighter permissions - on Bugzilla's files and directories if it knows what user the - webserver runs as. Look for the User - line in httpd.conf, and place that value in - the $webservergroup variable in - localconfig. Then rerun - checksetup.pl. -

2.2.4.2. Microsoft Internet Information Services

If you need, or for some reason even want, to use Microsoft's - Internet Information Services or - Personal Web Server you should be able - to. You will need to configure them to know how to run CGI scripts. - This is described in Microsoft Knowledge Base article - Q245225 - for Internet Information Services and - Q231998 - for Personal Web Server. -

Also, and this can't be stressed enough, make sure that files such as - localconfig and your data - directory are secured as described in Section 2.2.4.4. -

2.2.4.3. AOL Server

Ben FrantzDale reported success using AOL Server with Bugzilla. He - reported his experience and what appears below is based on that. -

AOL Server will have to be configured to run - CGI scripts, please consult - the documentation that came with your server for more information on - how to do this. -

Because AOL Server doesn't support .htaccess - files, you'll have to create a TCL - script. You should create an aolserver/modules/tcl/filter.tcl - file (the filename shouldn't matter) with the following contents (change - /bugzilla/ to the web-based path to - your Bugzilla installation): - 


  ns_register_filter preauth GET /bugzilla/localconfig filter_deny
-  ns_register_filter preauth GET /bugzilla/localconfig~ filter_deny
-  ns_register_filter preauth GET /bugzilla/\#localconfig\# filter_deny
-  ns_register_filter preauth GET /bugzilla/*.pl filter_deny
-  ns_register_filter preauth GET /bugzilla/syncshadowdb filter_deny
-  ns_register_filter preauth GET /bugzilla/runtests.sh filter_deny
-  ns_register_filter preauth GET /bugzilla/data/* filter_deny
-  ns_register_filter preauth GET /bugzilla/template/* filter_deny
-
-  proc filter_deny { why } {
-      ns_log Notice "filter_deny"
-      return "filter_return"
-  }
-

This probably doesn't account for all possible editor backup - files so you may wish to add some additional variations of - localconfig. For more information, see - bug 186383 or Bugtraq ID 6501. -

If you are using webdot from research.att.com (the default - configuration for the webdotbase paramater), you - will need to allow access to data/webdot/*.dot - for the reasearch.att.com machine. -

If you are using a local installation of GraphViz, you will need to allow - everybody to access *.png, - *.gif, *.jpg, and - *.map in the - data/webdot directory. -

2.2.4.4. Web Server Access Controls

Users of Apache can skip this section because - Bugzilla ships with .htaccess files which - restrict access in the manner required. - Users of other webservers, read on. -

There are several files in the Bugzilla directory - that should not be accessible from the web. You need to configure - your webserver so they they aren't. Not doing this may reveal - sensitive information such as database passwords. -

  • In the main Bugzilla directory, you should:

    • Block: - *.pl, *localconfig*, runtests.sh -

    • But allow: - localconfig.js, localconfig.rdf -

  • In data:

    • Block everything

    • But allow: - duplicates.rdf -

  • In data/webdot:

    • If you use a remote webdot server:

      • Block everything

      • But allow - *.dot - only for the remote webdot server

    • Otherwise, if you use a local GraphViz:

      • Block everything

      • But allow: - *.png, *.gif, *.jpg, *.map -

    • And if you don't use any dot:

      • Block everything

  • In Bugzilla:

    • Block everything

  • In template:

    • Block everything

You should test to make sure that the files mentioned above are - not accessible from the Internet, especially your - localconfig file which contains your database - password. To test, simply point your web browser at the file; for - example, to test mozilla.org's installation, we'd try to access - http://bugzilla.mozilla.org/localconfig. You should - get a 403 Forbidden - error. -

2.2.5. Bugzilla

Your Bugzilla should now be working. Access - http://<your-bugzilla-server>/ - - you should see the Bugzilla - front page. If not, consult the Troubleshooting section, - Section 2.5. -

Log in with the administrator account you defined in the last - checksetup.pl run. You should go through - the parameters on the Edit Parameters page - (see link in the footer) and see if there are any you wish to - change. - They key parameters are documented in Section 3.1; - you should certainly alter - maintainer and urlbase; - you may also want to alter - cookiepath or requirelogin. -

This would also be a good time to revisit the - localconfig file and make sure that the - names of the priorities, severities, platforms and operating systems - are those you wish to use when you start creating bugs. Remember - to rerun checksetup.pl if you change it. -

Bugzilla has several optional features which require extra - configuration. You can read about those in - Section 2.3. -

4.3. Customizing Who Can Change What

This feature should be considered experimental; the Bugzilla code you - will be changing is not stable, and could change or move between - versions. Be aware that if you make modifications as outlined here, - you may have - to re-make them or port them if Bugzilla changes internally between - versions, and you upgrade. -

Companies often have rules about which employees, or classes of employees, - are allowed to change certain things in the bug system. For example, - only the bug's designated QA Contact may be allowed to VERIFY the bug. - Bugzilla has been - designed to make it easy for you to write your own custom rules to define - who is allowed to make what sorts of value transition. -

For maximum flexibility, customizing this means editing Bugzilla's Perl - code. This gives the administrator complete control over exactly who is - allowed to do what. The relevant function is called - CheckCanChangeField(), - and is found in process_bug.cgi in your - Bugzilla directory. If you open that file and grep for - "sub CheckCanChangeField", you'll find it. -

This function has been carefully commented to allow you to see exactly - how it works, and give you an idea of how to make changes to it. Certain - marked sections should not be changed - these are the "plumbing" which - makes the rest of the function work. In between those sections, you'll - find snippets of code like: - 
    # Allow the owner to change anything.
-    if ($ownerid eq $whoid) {
-        return 1;
-    }
- It's fairly obvious what this piece of code does. -

So, how does one go about changing this function? Well, simple changes - can be made just be removing pieces - for example, if you wanted to - prevent any user adding a comment to a bug, just remove the lines marked - "Allow anyone to change comments." And if you want the reporter to have - no special rights on bugs they have filed, just remove the entire section - which refers to him. -

More complex customizations are not much harder. Basically, you add - a check in the right place in the function, i.e. after all the variables - you are using have been set up. So, don't look at $ownerid before - $ownerid has been obtained from the database. You can either add a - positive check, which returns 1 (allow) if certain conditions are true, - or a negative check, which returns 0 (deny.) E.g.: - 
    if ($field eq "qacontact") {
-        if (Bugzilla->user->groups("quality_assurance")) {
-            return 1;
-        } 
-        else {
-            return 0;
-        }
-    }
- This says that only users in the group "quality_assurance" can change - the QA Contact field of a bug. Getting more weird: - 
    if (($field eq "priority") &&
-        (Bugzilla->user->email =~ /.*\@example\.com$/))
-    {
-        if ($oldvalue eq "P1") {
-            return 1;
-        } 
-        else {
-            return 0;
-        }
-    }
- This says that if the user is trying to change the priority field, - and their email address is @example.com, they can only do so if the - old value of the field was "P1". Not very useful, but illustrative. -

For a list of possible field names, look in - data/versioncache for the list called - @::log_columns. If you need help writing custom - rules for your organization, ask in the newsgroup. -

The Bugzilla Guide - 2.17.7 - Development Release
PrevChapter 4. Customising BugzillaNext

4.2. Template Hooks

Template hooks are a way for extensions to Bugzilla to insert code - into the standard Bugzilla templates without modifying the template files - themselves. The hooks mechanism defines a consistent API for extending - the standard templates in a way that cleanly separates standard code - from extension code. Hooks reduce merge conflicts and make it easier - to write extensions that work across multiple versions of Bugzilla, - making upgrading a Bugzilla installation with installed extensions easier. -

A template hook is just a named place in a standard template file - where extension template files for that hook get processed. Each hook - has a corresponding directory in the Bugzilla directory tree. Hooking an - extension template to a hook is as simple as putting the extension file - into the hook's directory. When Bugzilla processes the standard template - and reaches the hook, it will process all extension templates in the - hook's directory. The hooks themselves can be added into any standard - template upon request by extension authors. -

To use hooks to extend a Bugzilla template, first make sure there is - a hook at the appropriate place within the template you want to extend. - Hooks appear in the standard Bugzilla templates as a single directive - in the format - [% Hook.process("name") %], - where name is the unique (within that template) - name of the hook. -

If you aren't sure which template you want to extend or just want - to browse the available hooks, either use your favorite multi-file search - tool (e.g. grep) to search the standard templates - for occurrences of Hook.process or browse - the directory tree in - BUGZILLA_ROOT/template/en/extension/hook/, - which contains a directory for each hook in the following location: -

BUGZILLA_ROOT/template/en/extension/hook/PATH_TO_STANDARD_TEMPLATE/STANDARD_TEMPLATE_NAME/HOOK_NAME/ -

If there is no hook at the appropriate place within the Bugzilla template - you want to extend, - file - a bug requesting one, specifying: -

the template for which you are requesting a hook;
where in the template you would like the hook to be placed - (line number/position for latest version of template in CVS - or description of location); -
the purpose of the hook;
a link to information about your extension, if any.

The Bugzilla reviewers will promptly review each hook request, - name the hook, add it to the template, check the new version - of the template into CVS, and create the corresponding directory in - BUGZILLA_ROOT/template/en/extension/hook/. -

You may optionally attach a patch to the bug which implements the hook - and check it in yourself after receiving approval from a Bugzilla - reviewer. The developers may suggest changes to the location of the - hook based on their analysis of your needs or so the hook can satisfy - the needs of multiple extensions, but the process of getting hooks - approved and checked in is not as stringent as the process for general - changes to Bugzilla, and any extension, whether released or still in - development, can have hooks added to meet their needs. -

After making sure the hook you need exists (or getting it added if not), - add your extension template to the directory within the Bugzilla - directory tree corresponding to the hook. -

That's it! Now, when the standard template containing the hook - is processed, your extension template will be processed at the point - where the hook appears. -

For example, let's say you have an extension named Projman that adds - project management capabilities to Bugzilla. Projman has an - administration interface edit-projects.cgi, - and you want to add a link to it into the navigation bar at the bottom - of every Bugzilla page for those users who are authorized - to administer projects. -

The navigation bar is generated by the template file - useful-links.html.tmpl, which is located in - the global/ subdirectory on the standard Bugzilla - template path - BUGZILLA_ROOT/template/en/default/. - Looking in useful-links.html.tmpl, you find - the following hook at the end of the list of standard Bugzilla - administration links: - 

...
-    [% ', <a href="editkeywords.cgi">keywords</a>' 
-                                              IF user.groups.editkeywords %]
-    [% Hook.process("edit") %]
-...

The corresponding directory for this hook is - BUGZILLA_ROOT/template/en/extension/hook/global/useful-links.html.tmpl/edit/. -

You put a template named - projman-edit-projects.html.tmpl - into that directory with the following content: - 

...[% ', <a href="edit-projects.cgi">projects</a>' IF user.groups.projman_admins %]

Voila! The link now appears after the other administration links in the - navigation bar for users in the projman_admins group. -

The Bugzilla Guide - 2.17.7 - Development Release
PrevChapter 4. Customising BugzillaNext

4.1. Template Customization

Administrators can configure the look and feel of Bugzilla without - having to edit Perl files or face the nightmare of massive merge - conflicts when they upgrade to a newer version in the future. -

Templatization also makes localized versions of Bugzilla possible, - for the first time. It's possible to have Bugzilla's UI language - determined by the user's browser. More information is available in - Section 4.1.5. -

4.1.1. What to Edit

The template directory structure is that there's a top level directory, - template, which contains a directory for - each installed localization. The default English templates are - therefore in en. Underneath that, there - is the default directory and optionally the - custom directory. The default - directory contains all the templates shipped with Bugzilla, whereas - the custom directory does not exist at first and - must be created if you want to use it. -

There are two different ways of editing Bugzilla's templates, - and which you use depends mainly on the method you plan to use to - upgrade Bugzilla. - The first method of making customizations is to directly edit the - templates in template/en/default. This is - probably the best method for small changes if you are going to use - the CVS method of upgrading, because if you then execute a - cvs update, any template fixes will get - automagically merged into your modified versions. -

If you use this method, your installation will break if CVS conflicts - occur. -

The other method is to copy the templates to be modified into a - mirrored directory - structure under template/en/custom. The templates - in this directory automatically override those in default. - This is the technique you - need to use if you use the overwriting method of upgrade, because - otherwise your changes will be lost. This method is also better if - you are using the CVS method of upgrading and are going to make major - changes, because it is guaranteed that the contents of this directory - will not be touched during an upgrade, and you can then decide whether - to continue using your own templates, or make the effort to merge your - changes into the new versions by hand. -

If you use this method, your installation may break if incompatible - changes are made to the template interface. If such changes are made - they will be documented in the release notes, provided you are using a - stable release of Bugzilla. If you use using unstable code, you will - need to deal with this one yourself, although if possible the changes - will be mentioned before they occur in the deprecations section of the - previous stable release's release notes. -

Don't directly edit the compiled templates in - data/template/* - your - changes will be lost when Template Toolkit recompiles them. -

It is recommended that you run ./checksetup.pl - after any template edits, especially if you've created a new file in - the custom directory. -

4.1.2. How To Edit Templates

If you are making template changes that you intend on submitting back - for inclusion in standard Bugzilla, you should read the relevant - sections of the - Developers' - Guide. -

The syntax of the Template Toolkit language is beyond the scope of - this guide. It's reasonably easy to pick up by looking at the current - templates; or, you can read the manual, available on the - Template Toolkit home - page. -

One thing you should take particular care about is the need - to properly HTML filter data that has been passed into the template. - This means that if the data can possibly contain special HTML characters - such as <, and the data was not intended to be HTML, they need to be - converted to entity form, ie &lt;. You use the 'html' filter in the - Template Toolkit to do this. If you forget, you may open up - your installation to cross-site scripting attacks. -

Also note that Bugzilla adds a few filters of its own, that are not - in standard Template Toolkit. In particular, the 'url_quote' filter - can convert characters that are illegal or have special meaning in URLs, - such as &, to the encoded form, ie %26. This actually encodes most - characters (but not the common ones such as letters and numbers and so - on), including the HTML-special characters, so there's never a need to - HTML filter afterwards. -

Editing templates is a good way of doing a "poor man's custom fields". - For example, if you don't use the Status Whiteboard, but want to have - a free-form text entry box for "Build Identifier", then you can just - edit the templates to change the field labels. It's still be called - status_whiteboard internally, but your users don't need to know that. -

4.1.3. Template Formats

Some CGIs have the ability to use more than one template. For - example, buglist.cgi can output bug lists as RDF or two - different forms of HTML (complex and simple). (Try this out - by appending &format=simple to a buglist.cgi - URL on your Bugzilla installation.) This - mechanism, called template 'formats', is extensible. -

To see if a CGI supports multiple output formats, grep the - CGI for "GetFormat". If it's not present, adding - multiple format support isn't too hard - see how it's done in - other CGIs, e.g. config.cgi. -

To make a new format template for a CGI which supports this, - open a current template for - that CGI and take note of the INTERFACE comment (if present.) This - comment defines what variables are passed into this template. If - there isn't one, I'm afraid you'll have to read the template and - the code to find out what information you get. -

Write your template in whatever markup or text style is appropriate. -

You now need to decide what content type you want your template - served as. Open up the localconfig file and find the - $contenttypes - variable. If your content type is not there, add it. Remember - the three- or four-letter tag assigned to you content type. - This tag will be part of the template filename. -

Save the template as <stubname>-<formatname>.<contenttypetag>.tmpl. - Try out the template by calling the CGI as - <cginame>.cgi?format=<formatname> . -

4.1.4. Particular Templates

There are a few templates you may be particularly interested in - customizing for your installation. -

index.html.tmpl: - This is the Bugzilla front page. -

global/header.html.tmpl: - This defines the header that goes on all Bugzilla pages. - The header includes the banner, which is what appears to users - and is probably what you want to edit instead. However the - header also includes the HTML HEAD section, so you could for - example add a stylesheet or META tag by editing the header. -

global/banner.html.tmpl: - This contains the "banner", the part of the header that appears - at the top of all Bugzilla pages. The default banner is reasonably - barren, so you'll probably want to customize this to give your - installation a distinctive look and feel. It is recommended you - preserve the Bugzilla version number in some form so the version - you are running can be determined, and users know what docs to read. -

global/footer.html.tmpl: - This defines the footer that goes on all Bugzilla pages. Editing - this is another way to quickly get a distinctive look and feel for - your Bugzilla installation. -

bug/create/user-message.html.tmpl: - This is a message that appears near the top of the bug reporting page. - By modifying this, you can tell your users how they should report - bugs. -

bug/create/create.html.tmpl and - bug/create/comment.txt.tmpl: - You may wish to get bug submitters to give certain bits of structured - information, each in a separate input widget, for which there is not a - field in the database. The bug entry system has been designed in an - extensible fashion to enable you to define arbitrary fields and widgets, - and have their values appear formatted in the initial - Description, rather than in database fields. An example of this - is the mozilla.org - guided - bug submission form. -

To make this work, create a custom template for - enter_bug.cgi (the default template, on which you - could base it, is create.html.tmpl), - and either call it create.html.tmpl or use a format and - call it create-<formatname>.html.tmpl. - Put it in the custom/bug/create - directory. In it, add widgets for each piece of information you'd like - collected - such as a build number, or set of steps to reproduce. -

Then, create a template like - custom/bug/create/comment.txt.tmpl, also named - after your format if you are using one, which - references the form fields you have created. When a bug report is - submitted, the initial comment attached to the bug report will be - formatted according to the layout of this template. -

For example, if your enter_bug template had a field - 
<input type="text" name="buildid" size="30">
- and then your comment.txt.tmpl had - 
BuildID: [% form.buildid %]
- then - 
BuildID: 20020303
- would appear in the initial checkin comment. -

4.1.5. Configuring Bugzilla to Detect the User's Language

Bugzilla honours the user's Accept: HTTP header. You can install - templates in other languages, and Bugzilla will pick the most appropriate - according to a priority order defined by you. Many - language templates can be obtained from http://www.bugzilla.org/download.html#localizations. Instructions - for submitting new languages are also available from that location. -

After untarring the localizations (or creating your own) in the - BUGZILLA_ROOT/template directory, - you must update the languages parameter to contain any - localizations you'd like to permit. You may also wish to set the - defaultlanguage parameter to something other than - "en" if you don't want Engish to be the default language. -

4.5. MySQL Bugzilla Database Introduction

This information comes straight from my life. I was forced to learn - how Bugzilla organizes database because of nitpicky requests from users - for tiny changes in wording, rather than having people re-educate - themselves or figure out how to work our procedures around the tool. It - sucks, but it can and will happen to you, so learn how the schema works - and deal with it when it comes.

So, here you are with your brand-new installation of Bugzilla. - You've got MySQL set up, Apache working right, Perl DBI and DBD talking - to the database flawlessly. Maybe you've even entered a few test bugs to - make sure email's working; people seem to be notified of new bugs and - changes, and you can enter and edit bugs to your heart's content. Perhaps - you've gone through the trouble of setting up a gateway for people to - submit bugs to your database via email, have had a few people test it, - and received rave reviews from your beta testers.

What's the next thing you do? Outline a training strategy for your - development team, of course, and bring them up to speed on the new tool - you've labored over for hours.

Your first training session starts off very well! You have a - captive audience which seems enraptured by the efficiency embodied in - this thing called "Bugzilla". You are caught up describing the nifty - features, how people can save favorite queries in the database, set them - up as headers and footers on their pages, customize their layouts, - generate reports, track status with greater efficiency than ever before, - leap tall buildings with a single bound and rescue Jane from the clutches - of Certain Death!

But Certain Death speaks up -- a tiny voice, from the dark corners - of the conference room. "I have a concern," the voice hisses from the - darkness, "about the use of the word 'verified'."

The room, previously filled with happy chatter, lapses into - reverential silence as Certain Death (better known as the Vice President - of Software Engineering) continues. "You see, for two years we've used - the word 'verified' to indicate that a developer or quality assurance - engineer has confirmed that, in fact, a bug is valid. I don't want to - lose two years of training to a new software product. You need to change - the bug status of 'verified' to 'approved' as soon as possible. To avoid - confusion, of course."

Oh no! Terror strikes your heart, as you find yourself mumbling - "yes, yes, I don't think that would be a problem," You review the changes - with Certain Death, and continue to jabber on, "no, it's not too big a - change. I mean, we have the source code, right? You know, 'Use the - Source, Luke' and all that... no problem," All the while you quiver - inside like a beached jellyfish bubbling, burbling, and boiling on a hot - Jamaican sand dune...

Thus begins your adventure into the heart of Bugzilla. You've been - forced to learn about non-portable enum() fields, varchar columns, and - tinyint definitions. The Adventure Awaits You!

4.5.1. Bugzilla Database Basics

If you were like me, at this point you're totally clueless about - the internals of MySQL, and if it weren't for this executive order from - the Vice President you couldn't care less about the difference between - a - "bigint" - - and a - "tinyint" - - entry in MySQL. I recommend you refer to the - MySQL documentation - . Below are the basics you need to know about the Bugzilla database. - Check the chart above for more details.

  1. To connect to your database:

    bash# - - mysql - - -u root -

    If this works without asking you for a password, - shame on you - - ! You should have locked your security down like the installation - instructions told you to. You can find details on locking down - your database in the Bugzilla FAQ in this directory (under - "Security"), or more robust security generalities in the - MySQL - searchable documentation. -

  2. You should now be at a prompt that looks like this:

    mysql> -

    At the prompt, if - "bugs" - - is the name you chose in the - localconfig - - file for your Bugzilla database, type:

    mysql - - use bugs; -

-

4.5.1.1. Bugzilla Database Tables

Imagine your MySQL database as a series of spreadsheets, and - you won't be too far off. If you use this command:

mysql> - show tables from bugs; -

you'll be able to see the names of all the - "spreadsheets" - (tables) in your database.

From the command issued above, ou should have some - output that looks like this: -

-  Here's an overview of what each table does. Most columns in each table have
-descriptive names that make it fairly trivial to figure out their jobs.
-
-attachments: This table stores all attachments to bugs. It tends to be your
-largest table, yet also generally has the fewest entries because file
-attachments are so (relatively) large.
-
-bugs:  This is the core of your system. The bugs table stores most of the
-current information about a bug, with the exception of the info stored in the
-other tables.
-
-bugs_activity:  This stores information regarding what changes are made to bugs
-when -- a history file.
-
-cc:  This tiny table simply stores all the CC information for any bug which has
-any entries in the CC field of the bug. Note that, like most other tables in
-Bugzilla, it does not refer to users by their user names, but by their unique
-userid, stored as a primary key in the profiles table.
-
-components: This stores the programs and components (or products and
-components, in newer Bugzilla parlance) for Bugzilla. Curiously, the "program"
-(product) field is the full name of the product, rather than some other unique
-identifier, like bug_id and user_id are elsewhere in the database.
-
-dependencies: Stores data about those cool dependency trees.
-
-fielddefs:  A nifty table that defines other tables. For instance, when you
-submit a form that changes the value of "AssignedTo" this table allows
-translation to the actual field name "assigned_to" for entry into MySQL.
-
-groups:  defines bitmasks for groups. A bitmask is a number that can uniquely
-identify group memberships. For instance, say the group that is allowed to
-tweak parameters is assigned a value of "1", the group that is allowed to edit
-users is assigned a "2", and the group that is allowed to create new groups is
-assigned the bitmask of "4". By uniquely combining the group bitmasks (much
-like the chmod command in UNIX,) you can identify a user is allowed to tweak
-parameters and create groups, but not edit users, by giving him a bitmask of
-"5", or a user allowed to edit users and create groups, but not tweak
-parameters, by giving him a bitmask of "6" Simple, huh?
-  If this makes no sense to you, try this at the mysql prompt:
-mysql> select * from groups;
-  You'll see the list, it makes much more sense that way.
-
-keyworddefs:  Definitions of keywords to be used
-
-keywords: Unlike what you'd think, this table holds which keywords are
-associated with which bug id's.
-
-logincookies: This stores every login cookie ever assigned to you for every
-machine you've ever logged into Bugzilla from. Curiously, it never does any
-housecleaning -- I see cookies in this file I've not used for months. However,
-since Bugzilla never expires your cookie (for convenience' sake), it makes
-sense.
-
-longdescs:  The meat of bugzilla -- here is where all user comments are stored!
-You've only got 2^24 bytes per comment (it's a mediumtext field), so speak
-sparingly -- that's only the amount of space the Old Testament from the Bible
-would take (uncompressed, 16 megabytes). Each comment is keyed to the
-bug_id to which it's attached, so the order is necessarily chronological, for
-comments are played back in the order in which they are received.
-
-milestones:  Interesting that milestones are associated with a specific product
-in this table, but Bugzilla does not yet support differing milestones by
-product through the standard configuration interfaces.
-
-namedqueries:  This is where everybody stores their "custom queries". Very
-cool feature; it beats the tar out of having to bookmark each cool query you
-construct.
-
-products:  What products you have, whether new bug entries are allowed for the
-product, what milestone you're working toward on that product, votes, etc. It
-will be nice when the components table supports these same features, so you
-could close a particular component for bug entry without having to close an
-entire product...
-
-profiles:  Ahh, so you were wondering where your precious user information was
-stored?  Here it is!  With the passwords in plain text for all to see! (but
-sshh... don't tell your users!)
-
-profiles_activity:  Need to know who did what when to who's profile?  This'll
-tell you, it's a pretty complete history.
-
-versions:  Version information for every product
-
-votes:  Who voted for what when
-
-watch:  Who (according to userid) is watching who's bugs (according to their
-userid).
-
-
-===
-THE DETAILS
-===
-
-  Ahh, so you're wondering just what to do with the information above?  At the
-mysql prompt, you can view any information about the columns in a table with
-this command (where "table" is the name of the table you wish to view):
-
-mysql> show columns from table;
-
-  You can also view all the data in a table with this command:
-
-mysql> select * from table;
-
-  -- note: this is a very bad idea to do on, for instance, the "bugs" table if
-you have 50,000 bugs. You'll be sitting there a while until you ctrl-c or
-50,000 bugs play across your screen.
-
-  You can limit the display from above a little with the command, where
-"column" is the name of the column for which you wish to restrict information:
-
-mysql> select * from table where (column = "some info");
-
-  -- or the reverse of this
-
-mysql> select * from table where (column != "some info");
-
-  Let's take our example from the introduction, and assume you need to change
-the word "verified" to "approved" in the resolution field. We know from the
-above information that the resolution is likely to be stored in the "bugs"
-table. Note we'll need to change a little perl code as well as this database
-change, but I won't plunge into that in this document. Let's verify the
-information is stored in the "bugs" table:
-
-mysql> show columns from bugs
-
-  (exceedingly long output truncated here)
-| bug_status| enum('UNCONFIRMED','NEW','ASSIGNED','REOPENED','RESOLVED','VERIFIED','CLOSED')||MUL | UNCONFIRMED||
-
-  Sorry about that long line. We see from this that the "bug status" column is
-an "enum field", which is a MySQL peculiarity where a string type field can
-only have certain types of entries. While I think this is very cool, it's not
-standard SQL. Anyway, we need to add the possible enum field entry
-'APPROVED' by altering the "bugs" table.
-
-mysql> ALTER table bugs CHANGE bug_status bug_status
-    -> enum("UNCONFIRMED", "NEW", "ASSIGNED", "REOPENED", "RESOLVED",
-    -> "VERIFIED", "APPROVED", "CLOSED") not null;
-
-    (note we can take three lines or more -- whatever you put in before the
-semicolon is evaluated as a single expression)
-
-Now if you do this:
-
-mysql> show columns from bugs;
-
-  you'll see that the bug_status field has an extra "APPROVED" enum that's
-available!  Cool thing, too, is that this is reflected on your query page as
-well -- you can query by the new status. But how's it fit into the existing
-scheme of things?
-  Looks like you need to go back and look for instances of the word "verified"
-in the perl code for Bugzilla -- wherever you find "verified", change it to
-"approved" and you're in business (make sure that's a case-insensitive search).
-Although you can query by the enum field, you can't give something a status
-of "APPROVED" until you make the perl changes. Note that this change I
-mentioned can also be done by editing checksetup.pl, which automates a lot of
-this. But you need to know this stuff anyway, right?

4.4. Modifying Your Running System

Bugzilla optimizes database lookups by storing all relatively - static information in the - versioncache file, located in the - data/ - subdirectory under your installation directory.

If you make a change to the structural data in your database (the - versions table for example), or to the - "constants" - - encoded in defparams.pl, you will need to remove - the cached content from the data directory (by doing a - "rm data/versioncache" - - ), or your changes won't show up.

versioncache - gets automatically regenerated whenever it's more than - an hour old, so Bugzilla will eventually notice your changes by itself, - but generally you want it to notice right away, so that you can test - things.

The Bugzilla Guide - 2.17.7 - Development Release
PrevChapter 2. Installing BugzillaNext

2.3. Optional Additional Configuration

Bugzilla has a number of optional features. This section describes how - to configure or enable them. -

2.3.1. Bug Graphs

If you have installed the necessary Perl modules you - can start collecting statistics for the nifty Bugzilla - graphs.

bash# crontab -e

This should bring up the crontab file in your editor. - Add a cron entry like this to run - collectstats.pl - daily at 5 after midnight: - 

5 0 * * * cd <your-bugzilla-directory> ; ./collectstats.pl

After two days have passed you'll be able to view bug graphs from - the Reports page.

2.3.2. Dependency Charts

As well as the text-based dependency trees, Bugzilla also - supports a graphical view of dependency relationships, using a - package called 'dot'. - Exactly how this works is controlled by the 'webdotbase' parameter, - which can have one of three values: -

  1. A complete file path to the command 'dot' (part of - GraphViz) - will generate the graphs locally -

  2. A URL prefix pointing to an installation of the webdot package will - generate the graphs remotely -

  3. A blank value will disable dependency graphing. -

-

The easiest way to get this working is to install - GraphViz. If you - do that, you need to - enable - server-side image maps in Apache. - Alternatively, you could set up a webdot server, or use the AT&T - public webdot server. This is the default for the webdotbase param, - but it's often overloaded and slow. Note that AT&T's server - won't work - if Bugzilla is only accessible using HARTS. - Editor's note: What the heck is HARTS? Google doesn't know... - -

2.3.3. The Whining Cron

What good are - bugs if they're not annoying? To help make them more so you - can set up Bugzilla's automatic whining system to complain at engineers - which leave their bugs in the NEW or REOPENED state without triaging them. -

- This can be done by - adding the following command as a daily crontab entry, in the same manner - as explained above for bug graphs. This example runs it at 12.55am. - 

55 0 * * * cd <your-bugzilla-directory> ; ./whineatnews.pl

2.3.4. Patch Viewer

Patch Viewer is the engine behind Bugzilla's graphical display of - code patches. You can integrate this with copies of the - cvs, lxr and - bonsai tools if you have them, by giving - the locations of your installation of these tools in - editparams.cgi. -

Patch Viewer also optionally will use the - cvs, diff and - interdiff - command-line utilities if they exist on the system. - Interdiff can be obtained from - http://cyberelk.net/tim/patchutils/. - If these programs are not in the system path, you can configure - their locations in localconfig. -

2.3.5. LDAP Authentication

LDAP authentication is a module for Bugzilla's plugin - authentication architecture. -

The existing authentication - scheme for Bugzilla uses email addresses as the primary user ID, and a - password to authenticate that user. All places within Bugzilla where - you need to deal with user ID (e.g assigning a bug) use the email - address. The LDAP authentication builds on top of this scheme, rather - than replacing it. The initial log in is done with a username and - password for the LDAP directory. This then fetches the email address - from LDAP and authenticates seamlessly in the standard Bugzilla - authentication scheme using this email address. If an account for this - address already exists in your Bugzilla system, it will log in to that - account. If no account for that email address exists, one is created at - the time of login. (In this case, Bugzilla will attempt to use the - "displayName" or "cn" attribute to determine the user's full name.) - After authentication, all other user-related tasks are still handled by - email address, not LDAP username. You still assign bugs by email - address, query on users by email address, etc. -

Because the Bugzilla account is not created until the first time - a user logs in, a user who has not yet logged is unknown to Bugzilla. - This means they cannot be used as an assignee or QA contact (default or - otherwise), added to any cc list, or any other such operation. One - possible workaround is the bugzilla_ldapsync.rb - script in the - contrib directory. Another possible solution is fixing - bug - 201069. -

Parameters required to use LDAP Authentication:

loginmethod

This parameter should be set to "LDAP" - only if you will be using an LDAP directory - for authentication. If you set this param to "LDAP" but - fail to set up the other parameters listed below you will not be - able to log back in to Bugzilla one you log out. If this happens - to you, you will need to manually edit - data/params and set loginmethod to - "DB". -

LDAPserver

This parameter should be set to the name (and optionally the - port) of your LDAP server. If no port is specified, it assumes - the default LDAP port of 389. -

Ex. "ldap.company.com" - or "ldap.company.com:3268" -

LDAPbinddn [Optional]

Some LDAP servers will not allow an anonymous bind to search - the directory. If this is the case with your configuration you - should set the LDAPbinddn parameter to the user account Bugzilla - should use instead of the anonymous bind. -

Ex. "cn=default,cn=user:password"

LDAPBaseDN

The LDAPBaseDN parameter should be set to the location in - your LDAP tree that you would like to search for email addresses. - Your uids should be unique under the DN specified here. -

Ex. "ou=People,o=Company"

LDAPuidattribute

The LDAPuidattribute parameter should be set to the attribute - which contains the unique UID of your users. The value retrieved - from this attribute will be used when attempting to bind as the - user to confirm their password. -

Ex. "uid"

LDAPmailattribute

The LDAPmailattribute parameter should be the name of the - attribute which contains the email address your users will enter - into the Bugzilla login boxes. -

Ex. "mail"

2.3.6. Prevent users injecting malicious - Javascript

It is possible for a Bugzilla user to take advantage of character - set encoding ambiguities to inject HTML into Bugzilla comments. This - could include malicious scripts. - Due to internationalization concerns, we are unable to - incorporate by default the code changes suggested by - the CERT advisory on this issue. - If your installation is for an English speaking audience only, making the - change below will prevent this problem. -

Simply locate the following line in - Bugzilla/CGI.pm: - 
$self->charset('');
- and change it to: - 
$self->charset('ISO-8859-1');
-

2.3.7. mod_throttle

It is possible for a user, by mistake or on purpose, to access - the database many times in a row which can result in very slow access - speeds for other users. If your Bugzilla installation is experiencing - this problem, you may install the Apache module - mod_throttle - which can limit connections by IP address. You may download this module - at - http://www.snert.com/Software/mod_throttle/. - Follow the instructions to install into your Apache install. - This module only functions with the Apache web - server! - The command you need is - ThrottleClientIP. See the - documentation - for more information.

2.3.8. TCP/IP Ports

A single-box Bugzilla only requires port 80, plus port 25 if - you are using the optional email interface. You should firewall all - other ports and/or disable services listening on them. -

2.3.9. Daemon Accounts

Many daemons, such as Apache's httpd and MySQL's mysqld default to - running as either "root" or "nobody". Running - as "root" introduces obvious security problems, but the - problems introduced by running everything as "nobody" may - not be so obvious. Basically, if you're running every daemon as - "nobody" and one of them gets compromised, they all get - compromised. For this reason it is recommended that you create a user - account for each daemon. -

1. General Questions

A.1.1. - What license is Bugzilla distributed under? -

- Bugzilla is covered by the Mozilla Public License. - See details at http://www.mozilla.org/MPL/. -

A.1.2. - How do I get commercial support for Bugzilla? -

- http://bugzilla.org/consulting.html - is a list of people and companies who have asked us to list them - as consultants for Bugzilla. -

There are several experienced - Bugzilla hackers on the mailing list/newsgroup who are willing - to make themselves available for generous compensation. - Try sending a message to the mailing list asking for a volunteer. -

A.1.3. - What major companies or projects are currently using Bugzilla - for bug-tracking? -

- There are dozens of major companies with public - Bugzilla sites to track bugs in their products. We have a fairly - complete list available on our website at - http://bugzilla.org/installation-list/. If you - have an installation of Bugzilla and would like to be added to the - list, whether it's a public install or not, simply e-mail - Gerv <gerv@mozilla.org>. -

A.1.4. - Who maintains Bugzilla? -

- A - core team, - led by Dave Miller (justdave@bugzilla.org). -

A.1.5. - How does Bugzilla stack up against other bug-tracking databases? -

- We can't find any head-to-head comparisons of Bugzilla against - other defect-tracking software. If you know of one, please - get in touch. However, from the author's personal - experience with other bug-trackers, Bugzilla offers - superior performance on commodity hardware, better price - (free!), more developer- friendly features (such as stored - queries, email integration, and platform independence), - improved scalability, open source code, greater - flexibility, and superior ease-of-use. -

If you happen to be a commercial bug-tracker vendor, please - step forward with a list of advantages your product has over - Bugzilla. We'd be happy to include it in the "Competitors" - section. -

A.1.6. - Why doesn't Bugzilla offer this or that feature or compatibility - with this other tracking software? -

- It may be that the support has not been built yet, or that you - have not yet found it. Bugzilla is making tremendous strides in - usability, customizability, scalability, and user interface. It - is widely considered the most complete and popular open-source - bug-tracking software in existence. -

That doesn't mean it can't use improvement! - You can help the project along by either hacking a patch yourself - that supports the functionality you require, or else submitting a - "Request for Enhancement" (RFE) using the bug submission interface - at bugzilla.mozilla.org. -

A.1.7. - Why MySQL? I'm interested in seeing Bugzilla run on - Oracle/Sybase/Msql/PostgreSQL/MSSQL. -

- MySQL was originally chosen because it is free, easy to install, - and was available for the hardware Netscape intended to run it on. -

There is currently work in progress to make Bugzilla work on - PostgreSQL and Sybase in the default distribution. You can track - the progress of these initiatives in bug 98304 - and bug 173130 - respectively. -

Once both of these are done, adding support for additional - database servers should be trivial. -

A.1.8. - What is /usr/bonsaitools/bin/perl? -

- Bugzilla used to have the path to perl on the shebang line set to - /usr/bonsaitools/bin/perl because when - Terry first started writing the code for mozilla.org he needed a - version of Perl and other tools that were completely under his - control. This location was abandoned for the 2.18 release in favor - of the more sensible /usr/bin/perl. If you - installed an older verion of Bugzilla and created the symlink we - suggested, you can remove it now (provided that you don't have - anything else, such as Bonsai, using it and you don't intend to - reinstall an older version of Bugzilla). -

A.1.9. - My perl is not located at /usr/bin/perl, is - there an easy way to change it everywhere it needs to be changed? -

- Yes, the following bit of perl magic will change all the shebang - lines. Be sure to change /usr/local/bin/perl - to your path to the perl binary. - 


perl -pi -e 's@#\!/usr/bin/perl@#\!/usr/local/bin/perl@' *cgi *pl
-

A.1.10. - Is there an easy way to change the Bugzilla cookie name? -

- At present, no. -

A.1.11. - Does bugzilla run under mod_perl? -

- At present, no. This is being worked on. -

2. Managerial Questions

A.2.1. - Is Bugzilla web-based, or do you have to have specific software or - a specific operating system on your machine? -

- It is web and e-mail based. -

A.2.2. - Does Bugzilla allow us to define our own priorities and levels? Do we - have complete freedom to change the labels of fields and format of them, and - the choice of acceptable values? -

- Yes. However, modifying some fields, notably those related to bug - progression states, also require adjusting the program logic to - compensate for the change. -

There is no GUI for adding fields to Bugzilla at this - time. You can follow development of this feature in - bug 91037 -

A.2.3. - Does Bugzilla provide any reporting features, metrics, graphs, etc? You - know, the type of stuff that management likes to see. :) -

- Yes. Look at http://bugzilla.mozilla.org/report.cgi - for samples of what Bugzilla can do in reporting and graphing. -

If you can not get the reports you want from the included reporting - scripts, it is possible to hook up a professional reporting package - such as Crystal Reports using ODBC. If you choose to do this, - beware that giving direct access to the database does contain some - security implications. Even if you give read-only access to the - bugs database it will bypass the secure bugs features of Bugzilla. -

A.2.4. - Is there email notification and if so, what do you see when you get an - email? -

- Email notification is user-configurable. By default, the bug id and - summary of the bug report accompany each email notification, along with - a list of the changes made. -

A.2.5. - Do users have to have any particular - type of email application? -

- Bugzilla email is sent in plain text, the most compatible mail format - on the planet. -

If you decide to use the bugzilla_email integration features - to allow Bugzilla to record responses to mail with the associated bug, - you may need to caution your users to set their mailer to "respond - to messages in the format in which they were sent". For security reasons - Bugzilla ignores HTML tags in comments, and if a user sends HTML-based - email into Bugzilla the resulting comment looks downright awful. -

-

A.2.6. - Does Bugzilla allow data to be imported and exported? If I had outsiders - write up a bug report using a MS Word bug template, could that template be - imported into "matching" fields? If I wanted to take the results of a query - and export that data to MS Excel, could I do that? -

- Bugzilla can output buglists as HTML (the default), CSV or RDF. - The link for CSV can be found at the bottom of the buglist in HTML - format. This CSV format can easily be imported into MS Excel or - other spreadsheet applications. -

To use the RDF format of the buglist it is necessary to append a - &ctype=rdf to the URL. RDF - is meant to be machine readable and thus it is assumed that the - URL would be generated programatically so there is no user visible - link to this format. -

Currently the only script included with Bugzilla that can import - data is importxml.pl which is intended to be - used for importing the data generated by the XML ctype of - show_bug.cgi in association with bug moving. - Any other use is left as an exercise for the user. -

There are also scripts included in the contrib/ - directory for using e-mail to import information into Bugzilla, - but these scripts are not currently supported and included for - educational purposes. -

A.2.7. - Has anyone converted Bugzilla to another language to be used in other - countries? Is it localizable? -

- Yes. For more information including available translated templates, - see http://www.bugzilla.org/download.html#localizations. - The admin interfaces are still not included in these translated - templates and is therefore still English only. Also, there may be - issues with the charset not being declared. See bug 126226 - for more information. -

A.2.8. - Can a user create and save reports? Can they do this in Word format? - Excel format? -

- Yes. No. Yes (using the CSV format). -

A.2.9. - Does Bugzilla provide record locking when there is simultaneous access - to the same bug? Does the second person get a notice that the bug is in use - or how are they notified? -

- Bugzilla does not lock records. It provides mid-air collision detection, - and offers the offending user a choice of options to deal with the conflict. -

A.2.10. - Are there any backup features provided? -

- MySQL, the database back-end for Bugzilla, allows hot-backup of data. - You can find strategies for dealing with backup considerations - at http://www.mysql.com/doc/B/a/Backup.html. -

A.2.11. - Can users be on the system while a backup is in progress? -

- Yes. However, commits to the database must wait - until the tables are unlocked. Bugzilla databases are typically - very small, and backups routinely take less than a minute. -

A.2.12. - What type of human resources are needed to be on staff to install and - maintain Bugzilla? Specifically, what type of skills does the person need to - have? I need to find out if we were to go with Bugzilla, what types of - individuals would we need to hire and how much would that cost vs buying an - "out-of-the-box" solution? -

- If Bugzilla is set up correctly from the start, continuing maintenance - needs are minimal and can be done easily using the web interface. -

Commercial Bug-tracking software typically costs somewhere upwards - of $20,000 or more for 5-10 floating licenses. Bugzilla consultation - is available from skilled members of the newsgroup. Simple questions - are answered there and then. -

A.2.13. - What time frame are we looking at if we decide to hire people to install - and maintain the Bugzilla? Is this something that takes hours or weeks to - install and a couple of hours per week to maintain and customize or is this - a multi-week install process, plus a full time job for 1 person, 2 people, - etc? -

- It all depends on your level of commitment. Someone with much Bugzilla - experience can get you up and running in less than a day, and - your Bugzilla install can run untended for years. If your - Bugzilla strategy is critical to your business workflow, hire somebody - with reasonable UNIX or Perl skills to handle your process management and - bug-tracking maintenance & customization. -

A.2.14. - Is there any licensing fee or other fees for using Bugzilla? Any - out-of-pocket cost other than the bodies needed as identified above? -

- No. MySQL asks, if you find their product valuable, that you purchase - a support contract from them that suits your needs. -

3. Bugzilla Security

A.3.1. - How do I completely disable MySQL security if it's giving me problems - (I've followed the instructions in the installation section of this guide)? -

- Run MySQL like this: "mysqld --skip-grant-tables". Please remember this - makes MySQL as secure as taping a $100 to the floor of a football stadium - bathroom for safekeeping. -

A.3.2. - Are there any security problems with Bugzilla? -

- The Bugzilla code has undergone a reasonably complete security audit, - and user-facing CGIs run under Perl's taint mode. However, - it is recommended that you closely examine permissions on your Bugzilla - installation, and follow the recommended security guidelines found - in The Bugzilla Guide. -

4. Bugzilla Email

A.4.1. - I have a user who doesn't want to receive any more email from Bugzilla. - How do I stop it entirely for this user? -

- The user should be able to set - this in user email preferences (uncheck all boxes) or you can add - their email address to the data/nomail file. -

A.4.2. - I'm evaluating/testing Bugzilla, and don't want it to send email to - anyone but me. How do I do it? -

- Edit the "newchangedmail" Param. Replace "To:" with "X-Real-To:", - replace "Cc:" with "X-Real-CC:", and add a "To: <youremailaddress>". -

A.4.3. - I want whineatnews.pl to whine at something other than new and - reopened bugs. How do I do it? -

- Try Klaas Freitag's excellent patch for "whineatassigned" - functionality. You can find it in bug 6679. This - patch is against an older version of Bugzilla, so you must apply - the diffs manually. - -

A.4.4. - How do I set up the email interface to submit/change bugs via email? -

- You can find an updated README.mailif file in the contrib/ directory - of your Bugzilla distribution that walks you through the setup. -

A.4.5. - Email takes FOREVER to reach me from Bugzilla -- it's extremely slow. - What gives? -

- If you are using sendmail, try enabling - sendmailnow in editparams.cgi. - -

If you are using an alternate MTA, - make sure the options given in Bugzilla/BugMail.pm - and any other place where sendmail is called from - are correct for your MTA. You should also ensure that the - sendmailnow param is set to on. -

A.4.6. - How come email from Bugzilla changes never reaches me? -

- Double-check that you have not turned off email in your user preferences. - Confirm that Bugzilla is able to send email by visiting the "Log In" - link of your Bugzilla installation and clicking the "Email me a password" - button after entering your email address. -

If you never receive mail from Bugzilla, chances are you do not have - sendmail in "/usr/lib/sendmail". Ensure sendmail lives in, or is symlinked - to, "/usr/lib/sendmail". -

5. Bugzilla Database

A.5.1. - I've heard Bugzilla can be used with Oracle? -

- Red Hat's old version of Bugzilla (based on 2.8) worked on Oracle, - but it is now so old as to be obsolete, and is totally unsupported. - Red Hat's newer version (based on 2.17.1 and soon to be merged into - the main distribution) runs on PostgreSQL. At this time we know of - no recent ports of Bugzilla to Oracle; to be honest, Bugzilla - doesn't need what Oracle offers. -

A.5.2. - I think my database might be corrupted, or contain invalid entries. What - do I do? -

- Run the "sanity check" utility - (sanitycheck.cgi) from your web browser to see! - If it finishes without errors, you're - probably OK. If it doesn't come back - OK (i.e. any red letters), there are certain things - Bugzilla can recover from and certain things it can't. If - it can't auto-recover, I hope you're familiar with - mysqladmin commands or have installed another way to - manage your database. Sanity Check, although it is a good - basic check on your database integrity, by no means is a - substitute for competent database administration and - avoiding deletion of data. It is not exhaustive, and was - created to do a basic check for the most common problems - in Bugzilla databases. -

A.5.3. - I want to manually edit some entries in my database. How? -

- There is no facility in Bugzilla itself to do this. It's also generally - not a smart thing to do if you don't know exactly what you're doing. - However, if you understand SQL you can use the mysql - command line utility to manually insert, delete and modify table - information. There are also more intuitive GUI clients available. - Personal favorites of the Bugzilla team are phpMyAdmin and MySQL Control - Center. -

A.5.4. - I think I've set up MySQL permissions correctly, but Bugzilla still can't - connect. -

- Try running MySQL from its binary: "mysqld --skip-grant-tables". This - will allow you to completely rule out grant tables as the cause of your - frustration. If this Bugzilla is able to connect at this point then - you need to check that you have granted proper permission to the user - password combo defined in localconfig. -

Running MySQL with this command line option is very insecure and - should only be done when not connected to the external network - as a troubleshooting step. -

A.5.5. - How do I synchronize bug information among multiple different Bugzilla - databases? -

- Well, you can synchronize or you can move bugs. Synchronization will - only work one way -- you can create a read-only copy of the database - at one site, and have it regularly updated at intervals from the main - database. -

MySQL has some synchronization features builtin to the latest releases. - It would be great if someone looked into the possibilities there - and provided a report to the newsgroup on how to effectively - synchronize two Bugzilla installations. -

If you simply need to transfer bugs from one Bugzilla to another, - checkout the "move.pl" script in the Bugzilla distribution. -

6. Bugzilla and Win32

A.6.1. - What is the easiest way to run Bugzilla on Win32 (Win98+/NT/2K)? -

- Remove Windows. Install Linux. Install Bugzilla. - The boss will never know the difference. -

A.6.2. - Is there a "Bundle::Bugzilla" equivalent for Win32? -

- Not currently. Bundle::Bugzilla enormously simplifies Bugzilla - installation on UNIX systems. If someone can volunteer to - create a suitable PPM bundle for Win32, it would be appreciated. -

A.6.3. - CGI's are failing with a "something.cgi is not a valid Windows NT - application" error. Why? -

- Depending on what Web server you are using, you will have to configure - the Web server to treat *.cgi files as CGI scripts. In IIS, you do this by - adding *.cgi to the App Mappings with the <path>\perl.exe %s %s as the - executable. -

Microsoft has some advice on this matter, as well: -

"Set application mappings. In the ISM, map the extension for the script - file(s) to the executable for the script interpreter. For example, you might - map the extension .py to Python.exe, the executable for the Python script - interpreter. Note For the ActiveState Perl script interpreter, the extension - .pl is associated with PerlIS.dll by default. If you want to change the - association of .pl to perl.exe, you need to change the application mapping. - In the mapping, you must add two percent (%) characters to the end of the - pathname for perl.exe, as shown in this example: c:\perl\bin\perl.exe %s %s" -

-

A.6.4. - I'm having trouble with the perl modules for NT not being able to talk to - to the database. -

- Your modules may be outdated or inaccurate. Try: -

  1. Hitting http://www.activestate.com/ActivePerl -

  2. Download ActivePerl -

  3. Go to your prompt -

  4. Type 'ppm' -

  5. PPM> install DBI DBD-mysql GD -

- I reckon TimeDate and Data::Dumper come with the activeperl. You can check - the ActiveState site for packages for installation through PPM. - http://www.activestate.com/Packages/. -

7. Bugzilla Usage

A.7.1. - How do I change my user name (email address) in Bugzilla? -

- New in 2.16 - go to the Account section of the Preferences. You will - be emailed at both addresses for confirmation. -

A.7.2. - The query page is very confusing. Isn't there a simpler way to query? -

- The interface was simplified by a UI designer for 2.16. Further - suggestions for improvement are welcome, but we won't sacrifice power for - simplicity. -

A.7.3. - I'm confused by the behavior of the "accept" button in the Show Bug form. - Why doesn't it assign the bug to me when I accept it? -

- The current behavior is acceptable to bugzilla.mozilla.org and most - users. You have your choice of patches to change this behavior, however. -

Add a "and accept bug" radio button
"Accept" button automatically assigns to you

- Note that these patches are somewhat dated. You will need to apply - them manually. -

A.7.4. - I can't upload anything into the database via the "Create Attachment" - link. What am I doing wrong? -

- The most likely cause is a very old browser or a browser that is - incompatible with file upload via POST. Download the latest Netscape, - Microsoft, or Mozilla browser to handle uploads correctly. -

A.7.5. - How do I change a keyword in Bugzilla, once some bugs are using it? -

- In the Bugzilla administrator UI, edit the keyword and it will let you - replace the old keyword name with a new one. This will cause a problem - with the keyword cache. Run sanitycheck.cgi to fix it. -

A.7.6. - Why can't I close bugs from the "Change Several Bugs at Once" page? -

- The logic flow currently used is RESOLVED, then VERIFIED, then CLOSED. - You can mass-CLOSE bugs from the change several - bugs at once page. but, every bug listed on the - page has to be in VERIFIED state before the control to do it will show - up on the form. You can also mass-VERIFY, but every bug listed has to be - RESOLVED in order for the control to show up on the form. The logic - behind this is that if you pick one of the bugs that's not VERIFIED and - try to CLOSE it, the bug change will fail miserably (thus killing any - changes in the list after it while doing the bulk change) so it doesn't - even give you the choice. -

8. Bugzilla Hacking

A.8.1. - What kind of style should I use for templatization? -

- Gerv and Myk suggest a 2-space indent, with embedded code sections on - their own line, in line with outer tags. Like this:


<fred>
-[% IF foo %]
-  <bar>
-  [% FOREACH x = barney %]
-    <tr>
-      <td>
-        [% x %]
-      </td>
-    <tr>
-  [% END %]
-[% END %]
-</fred>
-

Myk also recommends you turn on PRE_CHOMP in the template - initialization to prevent bloating of HTML with unnecessary whitespace. -

Please note that many have differing opinions on this subject, - and the existing templates in Bugzilla espouse both this and a 4-space - style. Either is acceptable; the above is preferred.

A.8.2. - What bugs are in Bugzilla right now? -

- Try this link to view current bugs or requests for - enhancement for Bugzilla. -

You can view bugs marked for 2.18 release - here. - This list includes bugs for the 2.18 release that have already - been fixed and checked into CVS. Please consult the - Bugzilla Project Page for details on how to - check current sources out of CVS so you can have these - bug fixes early! -

A.8.3. - How can I change the default priority to a null value? For instance, have the default - priority be "---" instead of "P2"? -

- This is well-documented in bug 49862. Ultimately, it's as easy as adding the "---" priority field to your - localconfig file in the appropriate area, re-running checksetup.pl, and then changing the - default priority in your browser using "editparams.cgi". -

A.8.4. - What's the best way to submit patches? What guidelines should I follow? -

  1. Enter a bug into bugzilla.mozilla.org for the "Bugzilla" - product. -

  2. Upload your patch as a unified diff (having used "diff -u" against - the current sources checked out of CVS), - or new source file by clicking - "Create a new attachment" link on the bug page you've just created, and - include any descriptions of database changes you may make, into the bug - ID you submitted in step #1. Be sure and click the "Patch" checkbox - to indicate the text you are sending is a patch! -

  3. Announce your patch and the associated URL - (http://bugzilla.mozilla.org/show_bug.cgi?id=XXXXXX) for discussion in - the newsgroup (netscape.public.mozilla.webtools). You'll get a really - good, fairly immediate reaction to the implications of your patch, - which will also give us an idea how well-received the change would - be. -

  4. If it passes muster with minimal modification, the person to whom - the bug is assigned in Bugzilla is responsible for seeing the patch - is checked into CVS. -

  5. Bask in the glory of the fact that you helped write the most successful - open-source bug-tracking software on the planet :) -

A "Secondary Section" is a named appendix or a front-matter section - of the Document that deals exclusively with the relationship of the - publishers or authors of the Document to the Document's overall subject - (or to related matters) and contains nothing that could fall directly - within that overall subject. (For example, if the Document is in part a - textbook of mathematics, a Secondary Section may not explain any - mathematics.) The relationship could be a matter of historical connection - with the subject or with related matters, or of legal, commercial, - philosophical, ethical or political position regarding them.

The "Invariant Sections" are certain Secondary Sections whose - titles are designated, as being those of Invariant Sections, in the - notice that says that the Document is released under this License.

The "Cover Texts" are certain short passages of text that are - listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says - that the Document is released under this License.

A "Transparent" copy of the Document means a machine-readable copy, - represented in a format whose specification is available to the general - public, whose contents can be viewed and edited directly and - straightforwardly with generic text editors or (for images composed of - pixels) generic paint programs or (for drawings) some widely available - drawing editor, and that is suitable for input to text formatters or for - automatic translation to a variety of formats suitable for input to text - formatters. A copy made in an otherwise Transparent file format whose - markup has been designed to thwart or discourage subsequent modification - by readers is not Transparent. A copy that is not "Transparent" is called - "Opaque".

Examples of suitable formats for Transparent copies include plain - ASCII without markup, Texinfo input format, LaTeX input format, SGML or - XML using a publicly available DTD, and standard-conforming simple HTML - designed for human modification. Opaque formats include PostScript, PDF, - proprietary formats that can be read and edited only by proprietary word - processors, SGML or XML for which the DTD and/or processing tools are not - generally available, and the machine-generated HTML produced by some word - processors for output purposes only.

The "Title Page" means, for a printed book, the title page itself, - plus such following pages as are needed to hold, legibly, the material - this License requires to appear in the title page. For works in formats - which do not have any title page as such, "Title Page" means the text - near the most prominent appearance of the work's title, preceding the - beginning of the body of the text.

3. Copying in Quantity

If you publish printed copies of the Document numbering more than - 100, and the Document's license notice requires Cover Texts, you must - enclose the copies in covers that carry, clearly and legibly, all these - Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts - on the back cover. Both covers must also clearly and legibly identify you - as the publisher of these copies. The front cover must present the full - title with all words of the title equally prominent and visible. You may - add other material on the covers in addition. Copying with changes - limited to the covers, as long as they preserve the title of the Document - and satisfy these conditions, can be treated as verbatim copying in other - respects.

If the required texts for either cover are too voluminous to fit - legibly, you should put the first ones listed (as many as fit reasonably) - on the actual cover, and continue the rest onto adjacent pages.

If you publish or distribute Opaque copies of the Document - numbering more than 100, you must either include a machine-readable - Transparent copy along with each Opaque copy, or state in or with each - Opaque copy a publicly-accessible computer-network location containing a - complete Transparent copy of the Document, free of added material, which - the general network-using public has access to download anonymously at no - charge using public-standard network protocols. If you use the latter - option, you must take reasonably prudent steps, when you begin - distribution of Opaque copies in quantity, to ensure that this - Transparent copy will remain thus accessible at the stated location until - at least one year after the last time you distribute an Opaque copy - (directly or through your agents or retailers) of that edition to the - public.

It is requested, but not required, that you contact the authors of - the Document well before redistributing any large number of copies, to - give them a chance to provide you with an updated version of the - Document.

4. Modifications

You may copy and distribute a Modified Version of the Document - under the conditions of sections 2 and 3 above, provided that you release - the Modified Version under precisely this License, with the Modified - Version filling the role of the Document, thus licensing distribution and - modification of the Modified Version to whoever possesses a copy of it. - In addition, you must do these things in the Modified Version:

  1. Use in the Title Page (and on the covers, if any) a title - distinct from that of the Document, and from those of previous - versions (which should, if there were any, be listed in the History - section of the Document). You may use the same title as a previous - version if the original publisher of that version gives - permission.

  2. List on the Title Page, as authors, one or more persons or - entities responsible for authorship of the modifications in the - Modified Version, together with at least five of the principal - authors of the Document (all of its principal authors, if it has less - than five).

  3. State on the Title page the name of the publisher of the - Modified Version, as the publisher.

  4. Preserve all the copyright notices of the Document.

  5. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices.

  6. Include, immediately after the copyright notices, a license - notice giving the public permission to use the Modified Version under - the terms of this License, in the form shown in the Addendum - below.

  7. Preserve in that license notice the full lists of Invariant - Sections and required Cover Texts given in the Document's license - notice.

  8. Include an unaltered copy of this License.

  9. Preserve the section entitled "History", and its title, and add - to it an item stating at least the title, year, new authors, and - publisher of the Modified Version as given on the Title Page. If - there is no section entitled "History" in the Document, create one - stating the title, year, authors, and publisher of the Document as - given on its Title Page, then add an item describing the Modified - Version as stated in the previous sentence.

  10. Preserve the network location, if any, given in the Document - for public access to a Transparent copy of the Document, and likewise - the network locations given in the Document for previous versions it - was based on. These may be placed in the "History" section. You may - omit a network location for a work that was published at least four - years before the Document itself, or if the original publisher of the - version it refers to gives permission.

  11. In any section entitled "Acknowledgements" or "Dedications", - preserve the section's title, and preserve in the section all the - substance and tone of each of the contributor acknowledgements and/or - dedications given therein.

  12. Preserve all the Invariant Sections of the Document, unaltered - in their text and in their titles. Section numbers or the equivalent - are not considered part of the section titles.

  13. Delete any section entitled "Endorsements". Such a section may - not be included in the Modified Version.

  14. Do not retitle any existing section as "Endorsements" or to - conflict in title with any Invariant Section.

If the Modified Version includes new front-matter sections or - appendices that qualify as Secondary Sections and contain no material - copied from the Document, you may at your option designate some or all of - these sections as invariant. To do this, add their titles to the list of - Invariant Sections in the Modified Version's license notice. These titles - must be distinct from any other section titles.

You may add a section entitled "Endorsements", provided it contains - nothing but endorsements of your Modified Version by various parties--for - example, statements of peer review or that the text has been approved by - an organization as the authoritative definition of a standard.

You may add a passage of up to five words as a Front-Cover Text, - and a passage of up to 25 words as a Back-Cover Text, to the end of the - list of Cover Texts in the Modified Version. Only one passage of - Front-Cover Text and one of Back-Cover Text may be added by (or through - arrangements made by) any one entity. If the Document already includes a - cover text for the same cover, previously added by you or by arrangement - made by the same entity you are acting on behalf of, you may not add - another; but you may replace the old one, on explicit permission from the - previous publisher that added the old one.

The author(s) and publisher(s) of the Document do not by this - License give permission to use their names for publicity for or to assert - or imply endorsement of any Modified Version.

Glossary

0-9, high ascii

.htaccess

Apache web server, and other NCSA-compliant web servers, - observe the convention of using files in directories called - .htaccess - - to restrict access to certain files. In Bugzilla, they are used - to keep secret files which would otherwise - compromise your installation - e.g. the - localconfig - file contains the password to your database. - curious.

A

Apache

In this context, Apache is the web server most commonly used - for serving up Bugzilla - pages. Contrary to popular belief, the apache web server has nothing - to do with the ancient and noble Native American tribe, but instead - derived its name from the fact that it was - "a patchy" - version of the original - NCSA - world-wide-web server.

Useful Directives when configuring Bugzilla

AddHandler

Tell Apache that it's OK to run CGI scripts.

AllowOverride, Options

These directives are used to tell Apache many things about - the directory they apply to. For Bugzilla's purposes, we need - them to allow script execution and .htaccess - overrides. -

DirectoryIndex

Used to tell Apache what files are indexes. If you can - not add index.cgi to the list of valid files, - you'll need to set $index_html to - 1 in localconfig so - ./checksetup.pl will create an - index.html that redirects to - index.cgi. -

ScriptInterpreterSource

Used when running Apache on windows so the shebang line - doesn't have to be changed in every Bugzilla script. -

For more information about how to configure Apache for Bugzilla, - see Section 2.2.4.1. -

B

Bug

A - "bug" - - in Bugzilla refers to an issue entered into the database which has an - associated number, assignments, comments, etc. Some also refer to a - "tickets" - or - "issues"; - in the context of Bugzilla, they are synonymous.

Bug Number

Each Bugzilla bug is assigned a number that uniquely identifies - that bug. The bug associated with a bug number can be pulled up via a - query, or easily from the very front page by typing the number in the - "Find" box.

Bugzilla

Bugzilla is the world-leading free software bug tracking system. -

C

Common Gateway Interface
(CGI)

CGI is an acronym for Common Gateway Interface. This is - a standard for interfacing an external application with a web server. Bugzilla - is an example of a CGI application. -

Component

A Component is a subsection of a Product. It should be a narrow - category, tailored to your organization. All Products must contain at - least one Component (and, as a matter of fact, creating a Product - with no Components will create an error in Bugzilla).

Comprehensive Perl Archive Network
(CPAN)

CPAN - - stands for the - "Comprehensive Perl Archive Network". - CPAN maintains a large number of extremely useful - Perl - modules - encapsulated chunks of code for performing a - particular task.

contrib

The contrib directory is - a location to put scripts that have been contributed to Bugzilla but - are not a part of the official distribution. These scripts are written - by third parties and may be in languages other than perl. For those - that are in perl, there may be additional modules or other requirements - than those of the offical distribution. -

Scripts in the contrib - directory are not offically supported by the Bugzilla team and may - break in between versions. -

-

D

daemon

A daemon is a computer program which runs in the background. In - general, most daemons are started at boot time via System V init - scripts, or through RC scripts on BSD-based systems. - mysqld, - the MySQL server, and - apache, - a web server, are generally run as daemons.

G

Groups

The word - "Groups" - - has a very special meaning to Bugzilla. Bugzilla's main security - mechanism comes by placing users in groups, and assigning those - groups certain privileges to view bugs in particular - Products - in the - Bugzilla - database.

J

JavaScript

JavaScript is cool, we should talk about it. -

M

Message Transport Agent
(MTA)

A Message Transport Agent is used to control the flow of email - on a system. Many unix based systems use - sendmail which is what - Bugzilla expects to find by default at /usr/sbin/sendmail. - Many other MTA's will work, but they all require that the - sendmailnow param be set to on. -

MySQL

MySQL is currently the required - RDBMS for Bugzilla. MySQL - can be downloaded from http://www.mysql.com. While you - should familiarize yourself with all of the documentation, some high - points are: -

Backup

Methods for backing up your Bugzilla database. -

Option Files

Information about how to configure MySQL using - my.cnf. -

Privilege System

Much more detailed information about the suggestions in - Section 2.2.2.1. -

P

Perl Package Manager
(PPM)

http://aspn.activestate.com/ASPN/Downloads/ActivePerl/PPM/ -

Product

A Product is a broad category of types of bugs, normally - representing a single piece of software or entity. In general, - there are several Components to a Product. A Product may define a - group (used for security) for all bugs entered into - its Components.

Perl

First written by Larry Wall, Perl is a remarkable program - language. It has the benefits of the flexibility of an interpreted - scripting language (such as shell script), combined with the speed - and power of a compiled language, such as C. - Bugzilla - - is maintained in Perl.

Q

QA

"QA", - "Q/A", and - "Q.A." - are short for - "Quality Assurance". - In most large software development organizations, there is a team - devoted to ensuring the product meets minimum standards before - shipping. This team will also generally want to track the progress of - bugs over their life cycle, thus the need for the - "QA Contact" - - field in a bug.

R

Relational DataBase Managment System
(RDBMS)

A relational database management system is a database system - that stores information in tables that are related to each other. -

Regular Expression
(regexp)

A regular expression is an expression used for pattern matching. - Documentation -

S

SGML -

SGML - - stands for - "Standard Generalized Markup Language". - Created in the 1980's to provide an extensible means to maintain - documentation based upon content instead of presentation, - SGML - - has withstood the test of time as a robust, powerful language. - XML - - - is the - "baby brother" - - of SGML; any valid - XML - - document it, by definition, a valid - SGML - - document. The document you are reading is written and maintained in - SGML, - and is also valid - XML - - if you modify the Document Type Definition.

T

Target Milestone

Target Milestones are Product goals. They are configurable on a - per-Product basis. Most software development houses have a concept of - - "milestones" - - where the people funding a project expect certain functionality on - certain dates. Bugzilla facilitates meeting these milestones by - giving you the ability to declare by which milestone a bug will be - fixed, or an enhancement will be implemented.

Tool Command Language
(TCL)

TCL is an open source scripting language available for Windows, - Macintosh, and Unix based systems. Bugzilla 1.0 was written in TCL but - never released. The first release of Bugzilla was 2.0, which was when - it was ported to perl. -

Z

Zarro Boogs Found

This is just a goofy way of saying that there were no bugs - found matching your query. When asked to explain this message, - Terry had the following to say: -

 

I've been asked to explain this ... way back when, when - Netscape released version 4.0 of its browser, we had a release - party. Naturally, there had been a big push to try and fix every - known bug before the release. Naturally, that hadn't actually - happened. (This is not unique to Netscape or to 4.0; the same thing - has happened with every software project I've ever seen.) Anyway, - at the release party, T-shirts were handed out that said something - like "Netscape 4.0: Zarro Boogs". Just like the software, the - T-shirt had no known bugs. Uh-huh. -

So, when you query for a list of bugs, and it gets no results, - you can think of this as a friendly reminder. Of *course* there are - bugs matching your query, they just aren't in the bugsystem yet... -

To create Groups:

  1. Select the "groups" - link in the footer.

  2. Take a moment to understand the instructions on the "Edit - Groups" screen, then select the "Add Group" link.

  3. Fill out the "Group", "Description", - and "User RegExp" fields. - "User RegExp" allows you to automatically - place all users who fulfill the Regular Expression into the new group. - When you have finished, click "Add".

    If specifying a domain in the regexp, make sure you end - the regexp with a $. Otherwise, when granting access to - "@mycompany\.com", you will allow access to - 'badperson@mycompany.com.cracker.net'. You need to use - '@mycompany\.com$' as the regexp.

  4. After you add your new group, edit the new group. On the - edit page, you can specify other groups that should be included - in this group and which groups should be permitted to add and delete - users from this group.

Note that group permissions are such that you need to be a member - of all the groups a bug is in, for whatever - reason, to see that bug. Similarly, you must be a member - of all of the entry groups for a product - to add bugs to a product and you must be a member - of all of the canedit groups for a product - in order to make any change to bugs in that - product. -

The Bugzilla Guide - 2.17.7 - Development Release
PrevChapter 5. Using BugzillaNext

5.8. Hints and Tips

This section distills some Bugzilla tips and best practices - that have been developed.

5.8.1. Autolinkification

Bugzilla comments are plain text - so typing <U> will - produce less-than, U, greater-than rather than underlined text. - However, Bugzilla will automatically make hyperlinks out of certain - sorts of text in comments. For example, the text - "http://www.bugzilla.org" will be turned into a link: - http://www.bugzilla.org. - Other strings which get linkified in the obvious manner are: -

bug 12345
comment 7
bug 23456, comment 53
attachment 4321
mailto:george@example.com
george@example.com
ftp://ftp.mozilla.org
Most other sorts of URL

-

A corollary here is that if you type a bug number in a comment, - you should put the word "bug" before it, so it gets autolinkified - for the convenience of others. -

5.8.2. Quicksearch

Quicksearch is a single-text-box query tool which uses - metacharacters to indicate what is to be searched. For example, typing - "foo|bar" - into Quicksearch would search for "foo" or "bar" in the - summary and status whiteboard of a bug; adding - ":BazProduct" would - search only in that product. -

You'll find the Quicksearch box on Bugzilla's - front page, along with a - Help - link which details how to use it.

5.8.3. Comments

If you are changing the fields on a bug, only comment if - either you have something pertinent to say, or Bugzilla requires it. - Otherwise, you may spam people unnecessarily with bug mail. - To take an example: a user can set up their account to filter out messages - where someone just adds themselves to the CC field of a bug - (which happens a lot.) If you come along, add yourself to the CC field, - and add a comment saying "Adding self to CC", then that person - gets a pointless piece of mail they would otherwise have avoided. -

Don't use sigs in comments. Signing your name ("Bill") is acceptable, - if you do it out of habit, but full mail/news-style - four line ASCII art creations are not. -

5.8.4. Attachments

Use attachments, rather than comments, for large chunks of ASCII data, - such as trace, debugging output files, or log files. That way, it doesn't - bloat the bug for everyone who wants to read it, and cause people to - receive fat, useless mails. -

Trim screenshots. There's no need to show the whole screen if - you are pointing out a single-pixel problem. -

Don't attach simple test cases (e.g. one HTML file, one - CSS file and an image) as a ZIP file. Instead, upload them in - reverse order and edit the referring file so that they point to the - attached files. This way, the test case works immediately - out of the bug. -

The Bugzilla Guide - 2.17.7 - Development Release
PrevChapter 2. Installing BugzillaNext

2.1. Installation

If you just want to use Bugzilla, - you do not need to install it. None of this chapter is relevant to - you. Ask your Bugzilla administrator - for the URL to access it over the web. -

The Bugzilla server software is usually installed on Linux or - Solaris. - If you are installing on another OS, check Section 2.4 - before you start your installation to see if there are any special - instructions. -

As an alternative to following these instructions, you may wish to - try Arne Schirmacher's unofficial and unsupported - Bugzilla - Installer, which installs Bugzilla and all its prerequisites - on Linux or Solaris systems. -

This guide assumes that you have administrative access to the - Bugzilla machine. It not possible to - install and run Bugzilla itself without administrative access except - in the very unlikely event that every single prerequisite is - already installed. -

The installation process may make your machine insecure for - short periods of time. Make sure there is a firewall between you - and the Internet. -

You are strongly recommended to make a backup of your system - before installing Bugzilla (and at regular intervals thereafter :-). -

In outline, the installation proceeds as follows: -

  1. Install Perl - (5.6.0 or above) -

  2. Install MySQL - (3.23.41 or above) -

  3. Install a Webserver -

  4. Install Bugzilla -

  5. Install Perl modules -

  6. Configure all of the above. -

2.1.1. Perl

Installed Version Test: perl -v

Any machine that doesn't have Perl on it is a sad machine indeed. - If you don't have it and your OS doesn't provide official packages, - visit http://www.perl.com. - Although Bugzilla runs with Perl 5.6.0, - it's a good idea to be using the latest stable version. - As of this writing, that is Perl 5.8.2.

2.1.2. MySQL

Installed Version Test: mysql -V

If you don't have it and your OS doesn't provide official packages, - visit http://www.mysql.com. You need MySQL version - 3.23.41 or higher. -

Many of the binary - versions of MySQL store their data files in - /var. - On some Unix systems, this is part of a smaller root partition, - and may not have room for your bug database. To change the data - directory, you have to build MySQL from source yourself, and - set it as an option to configure.

If you install from something other than a packaging/installation - system (such as .rpm, .dep, .exe, or .msi) make sure the MySQL server - is started when the machine boots. -

2.1.3. Web Server

Installed Version Test: view the default welcome page at - http://<your-machine>/

You have freedom of choice here, pretty much any web server that - is capable of running CGI - scripts will work. - However, we strongly recommend using the Apache web server - (either 1.3.x or 2.x), and - the installation instructions usually assume you are - using it. If you have got Bugzilla working using another webserver, - please share your experiences with us by filing a bug in Bugzilla Documentation. -

If you don't have Apache and your OS doesn't provide official packages, - visit http://httpd.apache.org/. -

2.1.4. Bugzilla

Download a Bugzilla tarball (or check it out from CVS) and place - it in a suitable directory, writable by the default web server user - (probably "nobody"). - Good locations are either directly in the main web space for your - web server or perhaps in - /usr/local - with a symbolic link from the web space. -

The default Bugzilla distribution is not designed to be placed - in a cgi-bin directory. This - includes any directory which is configured using the - ScriptAlias directive of Apache. -

Once all the files are in a web accessible directory, make that - directory writable by your webserver's user. This is a temporary step - until you run the - checksetup.pl - script, which locks down your installation.

2.1.5. Perl Modules

Bugzilla's installation process is based - on a script called checksetup.pl. - The first thing it checks is whether you have appropriate - versions of all the required - Perl modules. The aim of this section is to pass this check. - When it passes, - do not run it again, - but proceed to Section 2.2. -

At this point, you need to su to root. You should - remain as root until the end of the install. Then run: - 

bash# ./checksetup.pl

checksetup.pl will print out a list of the - required and optional Perl modules, together with the versions - (if any) installed on your machine. - The list of required modules is reasonably long; however, you - may already have several of them installed. -

There is a meta-module called Bundle::Bugzilla, - which installs all the other - modules with a single command. You should use this if you are running - Perl 5.6.1 or above. -

The preferred way of installing Perl modules is via CPAN on Unix, - or PPM on Windows (see Section 2.4.1.2). These - instructions assume you are using CPAN; if for some reason you need - to install the Perl modules manually, see - Appendix C. - 

bash# perl -MCPAN -e 'install "<modulename>"'

If you using Bundle::Bugzilla, invoke the magic CPAN command on it. - Otherwise, you need to work down the - list of modules that checksetup.pl says are - required, in the order given, invoking the command on each. -

Many people complain that Perl modules will not install for - them. Most times, the error messages complain that they are missing a - file in - "@INC". - Virtually every time, this error is due to permissions being set too - restrictively for you to compile Perl modules or not having the - necessary Perl development libraries installed on your system. - Consult your local UNIX systems administrator for help solving these - permissions issues; if you - are - the local UNIX sysadmin, please consult the newsgroup/mailing list - for further assistance or hire someone to help you out.

Here is a complete list of modules and their minimum versions. - Some modules have special installation notes, which follow. -

Required Perl modules: -

  1. AppConfig (1.52) -

  2. CGI (2.93) -

  3. Data::Dumper (any) -

  4. Date::Format (2.21) -

  5. DBI (1.32) -

  6. DBD::mysql - (2.1010) -

  7. File::Spec (0.82) -

  8. File::Temp (any) -

  9. Template - (2.08) -

  10. Text::Wrap (2001.0131) -

- - Optional Perl modules: -

  1. GD - (1.20) for bug charting -

  2. Chart::Base - (0.99c) for bug charting -

  3. GD::Graph - (any) for bug charting -

  4. GD::Text::Align - (any) for bug charting -

  5. XML::Parser - (any) for the XML interface -

  6. PatchReader - (0.9.1) for pretty HTML view of patches -

  7. MIME::Parser - (any) for the optional email interface -

-

2.1.5.1. DBD::mysql

The installation process will ask you a few questions about the - desired compilation target and your MySQL installation. For most of the - questions the provided default will be adequate, but when asked if your - desired target is the MySQL or mSQL packages, you should - select the MySQL-related ones. Later you will be asked if you wish to - provide backwards compatibility with the older MySQL packages; you - should answer YES to this question. The default is NO.

A host of 'localhost' should be fine. A testing user of 'test', - with a null password, should have sufficient access to run - tests on the 'test' database which MySQL creates upon installation. -

2.1.5.2. Template Toolkit (2.08)

When you install Template Toolkit, you'll get asked various - questions about features to enable. The defaults are fine, except - that it is recommended you use the high speed XS Stash of the Template - Toolkit, in order to achieve best performance. -

2.1.5.3. GD (1.20)

The GD module is only required if you want graphical reports. -

The Perl GD module requires some other libraries that may or - may not be installed on your system, including - libpng - and - libgd. - The full requirements are listed in the Perl GD module README. - If compiling GD fails, it's probably because you're - missing a required library.

The version of the GD module you need is very closely tied - to the libgd version installed on your system. - If you have a version 1.x of libgd the 2.x - versions of the GD module won't work for you. -

2.1.5.4. Chart::Base (0.99c)

The Chart::Base module is only required if you want graphical - reports. - Note that earlier versions that 0.99c used GIFs, which are no longer - supported by the latest versions of GD.

2.1.5.5. GD::Graph (any)

The GD::Graph module is only required if you want graphical - reports. -

2.1.5.6. GD::Text::Align (any)

The GD::Text::Align module is only required if you want graphical - reports. -

2.1.5.7. XML::Parser (any)

The XML::Parser module is only required if you want to import - XML bugs using the importxml.pl - script. This is required to use Bugzilla's "move bugs" feature; - you may also want to use it for migrating from another bug database. - XML::Parser requires that the - expat library is already installed on your machine. -

2.1.5.8. MIME::Parser (any)

The MIME::Parser module is only required if you want to use the - email interface - located in the contrib directory. -

2.1.5.9. PatchReader (0.9.1)

The PatchReader module is only required if you want to use - Patch Viewer, a - Bugzilla feature to show code patches in your web browser in a more - readable form. -

4.6. Integrating Bugzilla with Third-Party Tools

4.6.1. Bonsai

Bonsai is a web-based tool for managing - CVS, the Concurrent Versioning System - - . Using Bonsai, administrators can control open/closed status of trees, - query a fast relational database back-end for change, branch, and comment - information, and view changes made since the last time the tree was - closed. Bonsai - also integrates with - Tinderbox, the Mozilla automated build management system. -

4.6.2. CVS

CVS integration is best accomplished, at this point, using the - Bugzilla Email Gateway.

Follow the instructions in this Guide for enabling Bugzilla e-mail - integration. Ensure that your check-in script sends an email to your - Bugzilla e-mail gateway with the subject of - "[Bug XXXX]", - and you can have CVS check-in comments append to your Bugzilla bug. If - you want to have the bug be closed automatically, you'll have to modify - the contrib/bugzilla_email_append.pl script. -

There is also a CVSZilla project, based upon somewhat dated - Bugzilla code, to integrate CVS and Bugzilla through CVS' ability to - email. Check it out at: http://homepages.kcbbs.gen.nz/~tonyg/. -

4.6.3. Perforce SCM

You can find the project page for Bugzilla and Teamtrack Perforce - integration (p4dti) at: - http://www.ravenbrook.com/project/p4dti/ - - . - "p4dti" - - is now an officially supported product from Perforce, and you can find - the "Perforce Public Depot" p4dti page at - http://public.perforce.com/public/perforce/p4dti/index.html - - .

Integration of Perforce with Bugzilla, once patches are applied, is - seamless. Perforce replication information will appear below the comments - of each bug. Be certain you have a matching set of patches for the - Bugzilla version you are installing. p4dti is designed to support - multiple defect trackers, and maintains its own documentation for it. - Please consult the pages linked above for further information.

4.6.4. Tinderbox/Tinderbox2

Tinderbox is a continuous-build system which can integrate with - Bugzilla - see - http://www.mozilla.org/projects/tinderbox for details - of Tinderbox, and - http://tinderbox.mozilla.org/showbuilds.cgi to see it - in action.

If you want to use Bugzilla, first you need to create an account. - Consult with the administrator responsible for your installation of - Bugzilla for the URL you should use to access it. If you're - test-driving Bugzilla, use this URL: - http://landfill.bugzilla.org/bugzilla-tip/. -

  1. Click the - "Open a new Bugzilla account" - - link, enter your email address and, optionally, your name in the - spaces provided, then click - "Create Account" - - .

  2. Within moments, you should receive an email to the address - you provided, which contains your login name (generally the - same as the email address), and a password. - This password is randomly generated, but can be - changed to something more memorable.

  3. Click the - "Log In" - link in the footer at the bottom of the page in your browser, - enter your email address and password into the spaces provided, and - click - "Login". -

You are now logged in. Bugzilla uses cookies to remember you are - logged in so, unless you have cookies disabled or your IP address changes, - you should not have to log in again.

2.4. OS-Specific Installation Notes

Many aspects of the Bugzilla installation can be affected by the - the operating system you choose to install it on. Sometimes it can be made - easier and others more difficult. This section will attempt to help you - understand both the difficulties of running on specific operating systems - and the utilities available to make it easier. -

If you have anything to add or notes for an operating system not - covered, please file a bug in Bugzilla Documentation. -

2.4.1. Microsoft Windows

Making Bugzilla work on Windows is still a painful processes. - The Bugzilla Team is working to make it easier, but that goal is not - considered a top priority. If you wish to run Bugzilla, we still - recommend doing so on a Unix based system such as GNU/Linux. As of this - writing, all members of the Bugzilla team and all known large installations - run on Unix based systems. -

If after hearing all that, you have enough pain tolerance to attempt - installing Bugzilla on Win32, here are some pointers. - - Because this is a development version of the guide, these instructions - are subject to change without notice. In fact, the Bugzilla Team hopes - to have Bugzilla reasonably close to "out of - the box" compatibility with Windows by the 2.18 release. - -

2.4.1.1. Win32 Perl

Perl for Windows can be obtained from ActiveState. You should be - able to find a compiled binary at http://aspn.activestate.com/ASPN/Downloads/ActivePerl/. -

2.4.1.2. Perl Modules on Win32

Bugzilla on Windows requires the same perl modules found in - Section 2.1.5. The main difference is that - windows uses PPM instead of - CPAN. - 


C:\perl> ppm <module name>
-

The above syntax should work for all modules with the exception - of Template Toolkit. The Template Toolkit website - suggests using the instructions on OpenInteract's website. -

2.4.1.3. Code changes required to run on win32

As Bugzilla still doesn't run "out of the box" on - Windows, code has to be modified. This section lists the required - changes. -

2.4.1.3.1. Changes to checksetup.pl

In checksetup.pl, the line reading:


my $mysql_binaries = `which mysql`;
-

to


my $mysql_binaries = "D:\\mysql\\bin\\mysql";
-

And you'll also need to change:


my $webservergid = getgrnam($my_webservergroup)
-

to


my $webservergid = '8'
-

2.4.1.3.2. Changes to BugMail.pm

To make bug email work on Win32 (until - bug - 84876 lands), the - simplest way is to have the Net::SMTP Perl module installed and - change this:


open(SENDMAIL, "|/usr/lib/sendmail $sendmailparam -t -i") ||
-  die "Can't open sendmail";
-
-print SENDMAIL trim($msg) . "\n";
-close SENDMAIL;
-

to


use Net::SMTP;
-my $smtp_server = 'smtp.mycompany.com';  # change this
-
-# Use die on error, so that the mail will be in the 'unsent mails' and
-# can be sent from the sanity check page.
-my $smtp = Net::SMTP->new($smtp_server) ||
-  die 'Cannot connect to server \'$smtp_server\'';
-
-$smtp->mail('bugzilla-daemon@mycompany.com');  # change this
-$smtp->to($person);
-$smtp->data();
-$smtp->datasend($msg);
-$smtp->dataend();
-$smtp->quit;
-

Don't forget to change the name of your SMTP server and the - domain of the sending email address (after the '@') in the above - lines of code.

2.4.1.4. Serving the web pages

As is the case on Unix based systems, any web server should be - able to handle Bugzilla; however, the Bugzilla Team still recommends - Apache whenever asked. No matter what web server you choose, be sure - to pay attention to the security notes in Section 2.2.4.4. - More information on configuring specific web servers can be found in - Section 2.2.4. -

If using Apache on windows, you can set the ScriptInterpreterSource - directive in your Apache config to avoid having - to modify the first line of every script to contain your path to - perl instead of /usr/bin/perl. -

2.4.2. Mac OS X

Apple did not include the GD library with Mac OS X. Bugzilla - needs this for bug graphs.

You can install it using a program called - Fink, which is similar in nature to the CPAN installer, but installs - common GNU utilities. Fink is available from - http://sourceforge.net/projects/fink/.

Follow the instructions for setting up Fink. Once it's installed, - you'll want to use it to install the gd2 package. -

It will prompt you for a number of dependencies, type 'y' and hit - enter to install all of the dependencies and then watch it work. You will - then be able to use CPAN to - install the GD Perl module. -

To prevent creating conflicts with the software that Apple - installs by default, Fink creates its own directory tree at - /sw where it installs most of - the software that it installs. This means your libraries and headers be - at /sw/lib and - /sw/include instead of - /usr/lib and - /usr/local/include. When the - Perl module config script asks where your libgd is, be sure to tell it - /sw/lib. -

Also available via Fink is expat. After using fink to - install the expat package you will be able to install - XML::Parser using CPAN. There is one caveat. Unlike recent versions of - the GD module, XML::Parser doesn't prompt for the location of the - required libraries. When using CPAN, you will need to use the following - command sequence: - 


# perl -MCPAN -e'look XML::Parser'        
-# perl Makefile.PL EXPATLIBPATH=/sw/lib EXPATINCPATH=/sw/include
-# make; make test; make install           
-# exit                                    
-
The look command will download the module and spawn a - new shell with the extracted files as the current working directory. - The exit command will return you to your original shell. -
You should watch the output from these make commands, - especially "make test" as errors may prevent XML::Parser - from functioning correctly with Bugzilla. -

2.4.3. Linux-Mandrake 8.0

Linux-Mandrake 8.0 includes every required and optional library - for Bugzilla. The easiest way to install them is by using the - urpmi utility. If you follow these commands, you - should have everything you need for Bugzilla, and - ./checksetup.pl should not complain about any - missing libraries. You may already have some of these installed. - 


bash# urpmi perl-mysql
-bash# urpmi perl-chart
-bash# urpmi perl-gd
-bash# urpmi perl-MailTools             
-bash# urpmi apache-modules

The Bugzilla Guide - 2.17.7 - Development Release
PrevChapter 3. Administering BugzillaNext

3.1. Bugzilla Configuration

Bugzilla is configured by changing various parameters, accessed - from the "Edit parameters" link in the page footer. Here are - some of the key parameters on that page. You should run down this - list and set them appropriately after installing Bugzilla.

  1. - maintainer: - The maintainer parameter is the email address of the person - responsible for maintaining this - Bugzilla installation. The address need not be that of a valid Bugzilla - account.

  2. urlbase: - This parameter defines the fully qualified domain name and web - server path to your Bugzilla installation.

    For example, if your Bugzilla query page is - http://www.foo.com/bugzilla/query.cgi, - set your "urlbase" - to http://www.foo.com/bugzilla/.

  3. makeproductgroups: - This dictates whether or not to automatically create groups - when new products are created. -

  4. useentrygroupdefault: - Bugzilla products can have a group associated with them, so that - certain users can only see bugs in certain products. When this - parameter is set to "on", this - causes the initial group controls on newly created products - to place all newly-created bugs in the group - having the same name as the product immediately. - After a product is initially created, the group controls - can be further adjusted without interference by - this mechanism.

  5. shadowdb: - You run into an interesting problem when Bugzilla reaches a - high level of continuous activity. MySQL supports only table-level - write locking. What this means is that if someone needs to make a - change to a bug, they will lock the entire table until the operation - is complete. Locking for write also blocks reads until the write is - complete. Note that more recent versions of mysql support row level - locking using different table types. These types are slower than the - standard type, and Bugzilla does not yet take advantage of features - such as transactions which would justify this speed decrease. The - Bugzilla team are, however, happy to hear about any experiences with - row level locking and Bugzilla.

    The "shadowdb" - parameter was designed to get around this limitation. While only a - single user is allowed to write to a table at a time, reads can - continue unimpeded on a read-only shadow copy of the database. - Although your database size will double, a shadow database can cause - an enormous performance improvement when implemented on extremely - high-traffic Bugzilla databases.

    As a guide, on reasonably old hardware, mozilla.org began needing - "shadowdb" - when they reached around 40,000 Bugzilla users with several hundred - Bugzilla bug changes and comments per day.

    The value of the parameter defines the name of the - shadow bug database. You will need to set the host and port settings - from the params page, and set up replication in your database server - so that updates reach this readonly mirror. Consult your database - documentation for more detail.

  6. shutdownhtml: - - If you need to shut down Bugzilla to perform administration, enter - some descriptive HTML here and anyone who tries to use Bugzilla will - receive a page to that effect. Obviously, editparams.cgi will - still be accessible so you can remove the HTML and re-enable Bugzilla. - :-) -

  7. passwordmail: - - Every time a user creates an account, the text of - this parameter (with substitutions) is sent to the new user along with - their password message.

    Add any text you wish to the "passwordmail" parameter box. For - instance, many people choose to use this box to give a quick training - blurb about how to use Bugzilla at your site.

  8. movebugs: - - This option is an undocumented feature to allow moving bugs - between separate Bugzilla installations. You will need to understand - the source code in order to use this feature. Please consult - movebugs.pl in your Bugzilla source tree for - further documentation, such as it is. -

  9. useqacontact: - - This allows you to define an email address for each component, in - addition - to that of the default owner, who will be sent carbon copies of - incoming bugs.

  10. usestatuswhiteboard: - This defines whether you wish to have a free-form, overwritable field - associated with each bug. The advantage of the Status Whiteboard is - that it can be deleted or modified with ease, and provides an - easily-searchable field for indexing some bugs that have some trait - in common. -

  11. whinedays: - Set this to the number of days you want to let bugs go - in the NEW or REOPENED state before notifying people they have - untouched new bugs. If you do not plan to use this feature, simply do - not set up the whining cron job described in the installation - instructions, or set this value to "0" (never whine).

  12. commenton*: - All these - fields allow you to dictate what changes can pass without comment, - and which must have a comment from the person who changed them. - Often, administrators will allow users to add themselves to the CC - list, accept bugs, or change the Status Whiteboard without adding a - comment as to their reasons for the change, yet require that most - other changes come with an explanation.

    Set the "commenton" options according to your site policy. It - is a wise idea to require comments when users resolve, reassign, or - reopen bugs at the very least. -

    It is generally far better to require a developer comment - when resolving bugs than not. Few things are more annoying to bug - database users than having a developer mark a bug "fixed" without - any comment as to what the fix was (or even that it was truly - fixed!)

    -

  13. supportwatchers: - - Turning on this option allows users to ask to receive copies of - all a particular other user's bug email. This is, of - course, subject to the groupset restrictions on the bug; if the - "watcher" - would not normally be allowed to view a bug, the watcher cannot get - around the system by setting herself up to watch the bugs of someone - with bugs outside her privileges. They would still only receive email - updates for those bugs she could normally view.

5.7. Patch Viewer

Viewing and reviewing patches in Bugzilla is often difficult due to - lack of context, improper format and the inherent readability issues that - raw patches present. Patch Viewer is an enhancement to Bugzilla designed - to fix that by offering increased context, linking to sections, and - integrating with Bonsai, LXR and CVS.

Patch viewer allows you to:

View patches in color, with side-by-side view rather than trying - to interpret the contents of the patch.
See the difference between two patches.
Get more context in a patch.
Collapse and expand sections of a patch for easy - reading.
Link to a particular section of a patch for discussion or - review
Go to Bonsai or LXR to see more context, blame, and - cross-references for the part of the patch you are looking at
Create a rawtext unified format diff out of any patch, no - matter what format it came from

5.7.1. Viewing Patches in Patch Viewer

The main way to view a patch in patch viewer is to click on the - "Diff" link next to a patch in the Attachments list on a bug. You may - also do this within the edit window by clicking the "View Attachment As - Diff" button in the Edit Attachment screen.

5.7.2. Seeing the Difference Between Two Patches

To see the difference between two patches, you must first view the - newer patch in Patch Viewer. Then select the older patch from the - dropdown at the top of the page ("Differences between [dropdown] and - this patch") and click the "Diff" button. This will show you what - is new or changed in the newer patch.

5.7.3. Getting More Context in a Patch

To get more context in a patch, you put a number in the textbox at - the top of Patch Viewer ("Patch / File / [textbox]") and hit enter. - This will give you that many lines of context before and after each - change. Alternatively, you can click on the "File" link there and it - will show each change in the full context of the file. This feature only - works against files that were diffed using "cvs diff".

5.7.4. Collapsing and Expanding Sections of a Patch

To view only a certain set of files in a patch (for example, if a - patch is absolutely huge and you want to only review part of it at a - time), you can click the "(+)" and "(-)" links next to each file (to - expand it or collapse it). If you want to collapse all files or expand - all files, you can click the "Collapse All" and "Expand All" links at the - top of the page.

5.7.5. Linking to a Section of a Patch

To link to a section of a patch (for example, if you want to be - able to give someone a URL to show them which part you are talking - about) you simply click the "Link Here" link on the section header. The - resulting URL can be copied and used in discussion. (Copy Link - Location in Mozilla works as well.)

5.7.6. Going to Bonsai and LXR

To go to Bonsai to get blame for the lines you are interested in, - you can click the "Lines XX-YY" link on the section header you are - interested in. This works even if the patch is against an old - version of the file, since Bonsai stores all versions of the file.

To go to LXR, you click on the filename on the file header - (unfortunately, since LXR only does the most recent version, line - numbers are likely to rot).

5.7.7. Creating a Unified Diff

If the patch is not in a format that you like, you can turn it - into a unified diff format by clicking the "Raw Unified" link at the top - of the page.

Products - - are the broadest category in Bugzilla, and tend to represent real-world - shipping products. E.g. if your company makes computer games, - you should have one product per game, perhaps a "Common" product for - units of technology used in multiple games, and maybe a few special - products (Website, Administration...)

Many of Bugzilla's settings are configurable on a per-product - basis. The number of "votes" available to users is set per-product, - as is the number of votes - required to move a bug automatically from the UNCONFIRMED status to the - NEW status.

To create a new product:

  1. Select "products" from the footer

  2. Select the "Add" link in the bottom right

  3. Enter the name of the product and a description. The - Description field may contain HTML.

Don't worry about the "Closed for bug entry", "Maximum Votes - per person", "Maximum votes a person can put on a single bug", - "Number of votes a bug in this Product needs to automatically get out - of the UNCOMFIRMED state", and "Version" options yet. We'll cover - those in a few moments. -

The Bugzilla Search page is is the interface where you can find - any bug report, comment, or patch currently in the Bugzilla system. You - can play with it here: - http://landfill.bugzilla.org/bugzilla-tip/query.cgi.

The Search page has controls for selecting different possible - values for all of the fields in a bug, as described above. For some - fields, multiple values can be selected. In those cases, Bugzilla - returns bugs where the content of the field matches any one of the selected - values. If none is selected, then the field can take any value.

Once you've run a search, you can save it as a Saved Search, which - appears in the page footer.

Highly advanced querying is done using Boolean Charts. See the - Boolean Charts help link on the Search page for more information.

PrevChapter 2. Installing BugzillaNext

2.5. Troubleshooting

This section gives solutions to common Bugzilla installation - problems. If none of the section headings seems to match your - problem, read the general advice. -

2.5.1. General Advice

If you can't get checksetup.pl to run to - completion, it normally explains what's wrong and how to fix it. - If you can't work it out, or if it's being uncommunicative, post - the errors in the - netscape.public.mozilla.webtools - newsgroup. -

If you have made it all the way through - Section 2.1 (Installation) and - Section 2.2 (Configuration) but - accessing the Bugzilla URL doesn't work, - the first thing to do is to check your webserver error log. For - Apache, this is often located at - /etc/logs/httpd/error_log. The error messages - you see may be self-explanatory enough to enable you to diagnose and - fix the problem. If not, see below for some commonly-encountered - errors. If that doesn't help, post the errors to the newsgroup. -

2.5.2. I installed a Perl module, but - checksetup.pl claims it's not installed!

You have two versions of Perl on your machine. You are installing - modules into one, and Bugzilla is using the other. Rerun the CPAN - commands (or manual compile) using the full path to Perl from the - top of checksetup.pl. This will make sure you - are installing the modules in the right place. -

2.5.3. Bundle::Bugzilla makes me upgrade to Perl 5.6.1

Try executing perl -MCPAN -e 'install CPAN' - and then continuing. -

Certain older versions of the CPAN toolset were somewhat naive about how - to upgrade Perl modules. When a couple of modules got rolled into the core - Perl distribution for 5.6.1, CPAN thought that the best way to get those - modules up to date was to haul down the Perl distribution itself and - build it. Needless to say, this has caused headaches for just about - everybody. Upgrading to a newer version of CPAN with the - commandline above should fix things. -

2.5.4. DBD::Sponge::db prepare failed

The following error message may appear due to a bug in DBD::mysql - (over which the Bugzilla team have no control): - 

 DBD::Sponge::db prepare failed: Cannot determine NUM_OF_FIELDS at D:/Perl/site/lib/DBD/mysql.pm line 248.
-  SV = NULL(0x0) at 0x20fc444
-  REFCNT = 1
-  FLAGS = (PADBUSY,PADMY)
-

To fix this, go to - <path-to-perl>/lib/DBD/sponge.pm - in your Perl installation and replace - 

 my $numFields;
- if ($attribs->{'NUM_OF_FIELDS'}) {
-     $numFields = $attribs->{'NUM_OF_FIELDS'};
- } elsif ($attribs->{'NAME'}) {
-     $numFields = @{$attribs->{NAME}};
-

by - 

 my $numFields;
- if ($attribs->{'NUM_OF_FIELDS'}) {
-     $numFields = $attribs->{'NUM_OF_FIELDS'};
- } elsif ($attribs->{'NAMES'}) {
-     $numFields = @{$attribs->{NAMES}};
-

(note the S added to NAME.) -

2.5.5. cannot chdir(/var/spool/mqueue)

If you are installing Bugzilla on SuSE Linux, or some other - distributions with - "paranoid" - security options, it is possible that the checksetup.pl script may fail - with the error: -
cannot chdir(/var/spool/mqueue): Permission denied
-

2.5.6. Your vendor has not defined Fcntl macro O_NOINHERIT

This is caused by a bug in the version of - File::Temp that is distributed with perl - 5.6.0. Many minor variations of this error have been reported: - 

Your vendor has not defined Fcntl macro O_NOINHERIT, used 
-at /usr/lib/perl5/site_perl/5.6.0/File/Temp.pm line 208.
-
-Your vendor has not defined Fcntl macro O_EXLOCK, used

-
-Your vendor has not defined Fcntl macro O_TEMPORARY, used 
-at /usr/lib/perl5/site_perl/5.6.0/File/Temp.pm line 233.

Numerous people have reported that upgrading to version 5.6.1 - or higher solved the problem for them. A less involved fix is to apply - the following patch, which is also - available as a patch file. -

3.9. Upgrading to New Releases

Upgrading is a one-way process. You should backup your database - and current Bugzilla directory before attempting the upgrade. If you wish - to revert to the old Bugzilla version for any reason, you will have to - restore from these backups. -

Upgrading Bugzilla is something we all want to do from time to time, - be it to get new features or pick up the latest security fix. How easy - it is to update depends on a few factors. -

There are also three different methods to upgrade your installation. -

  1. Using CVS (Example 3-1)

  2. Downloading a new tarball (Example 3-2)

  3. Applying the relevant patches (Example 3-3)

Which options are available to you may depend on how large a jump - you are making and/or your network configuration. -

Revisions are normally released to fix security vulnerabilities - and are distinguished by an increase in the third number. For example, - when 2.16.2 was released, it was a revision to 2.16.1. -

Point releases are normally released when the Bugzilla team feels - that there has been a significant amount of progress made between the - last point release and the current time. These are often proceeded by a - stabilization period and release candidates, however the use of - development versions or release candidates is beyond the scope of this - document. Point releases can be distinguished by an increase in the - second number, or minor version. For example, 2.16.2 is a newer point - release than 2.14.5. -

The examples in this section are written as if you were updating - to version 2.16.2. The procedures are the same regardless if you are - updating to a new point release or a new revision. However, the chance - of running into trouble increases when upgrading to a new point release, - escpecially if you've made local changes. -

These examples also assume that your Bugzilla installation is at - /var/www/html/bugzilla. If that is not the case, - simply substitute the proper paths where appropriate. -

Example 3-1. Upgrading using CVS

Every release of Bugzilla, whether it is a revision or a point - release, is tagged in CVS. Also, every tarball we have distributed - since version 2.12 has been primed for using CVS. This does, however, - require that you are able to access cvs-mirror.mozilla.org on port - 2401. - -

If you can do this, updating using CVS is probably the most - painless method, especially if you have a lot of local changes. -

- 


bash$ cd /var/www/html/bugzilla
-bash$ cvs login
-Logging in to :pserver:anonymous@cvs-mirror.mozilla.org:2401/cvsroot
-CVS password: anonymous
-bash$ cvs -q update -r BUGZILLA-2_16_2 -dP
-P checksetup.pl
-P collectstats.pl
-P globals.pl
-P docs/rel_notes.txt
-P template/en/default/list/quips.html.tmpl
-

If a line in the output from cvs update - begins with a C that represents a - file with local changes that CVS was unable to properly merge. You - need to resolve these conflicts manually before Bugzilla (or at - least the portion using that file) will be usable. -

- -

You also need to run ./checksetup.pl - before your Bugzilla upgrade will be complete. -

-

Example 3-2. Upgrading using the tarball

If you are unable or unwilling to use CVS, another option that's - always available is to download the latest tarball. This is the most - difficult option to use, especially if you have local changes. - 


bash$ cd /var/www/html
-bash$ wget ftp://ftp.mozilla.org/pub/webtools/bugzilla-2.16.2.tar.gz
-Output omitted
-bash$ tar xzvf bugzilla-2.16.2.tar.gz
-bugzilla-2.16.2/
-bugzilla-2.16.2/.cvsignore
-bugzilla-2.16.2/1x1.gif
-Output truncated
-bash$ cd bugzilla-2.16.2
-bash$ cp ../bugzilla/localconfig* .
-bash$ cp -r ../bugzilla/data .
-bash$ cd ..
-bash$ mv bugzilla bugzilla.old
-bash$ mv bugzilla-2.16.2 bugzilla
-bash$ cd bugzilla
-bash$ ./checksetup.pl
-Output omitted
-

The cp commands both end with periods which - is a very important detail, it tells the shell that the destination - directory is the current working directory. Also, the period at the - beginning of the ./checksetup.pl is important and - can not be omitted. -

- -

You will now have to reapply any changes you have made to your - local installation manually. -

-

Example 3-3. Upgrading using patches

The Bugzilla team will normally make a patch file available for - revisions to go from the most recent revision to the new one. You could - also read the release notes and grab the patches attached to the - mentioned bug, but it is safer to use the released patch file as - sometimes patches get changed before they get checked in. - It is also theoretically possible to - scour the fixed bug list and pick and choose which patches to apply - from a point release, but this is not recommended either as what you'll - end up with is a hodge podge Bugzilla that isn't really any version. - This would also make it more difficult to upgrade in the future. - 


bash$ cd /var/www/html/bugzilla
-bash$ wget ftp://ftp.mozilla.org/pub/webtools/bugzilla-2.16.1-to-2.16.2.diff.gz
-Output omitted
-bash$ gunzip bugzilla-2.16.1-to-2.16.2.diff.gz
-bash$ patch -p1 < bugzilla-2.16.1-to-2.16.2.diff
-patching file checksetup.pl
-patching file collectstats.pl
-patching file globals.pl
-

If you do this, beware that this doesn't change the entires in - your CVS directory so it may make - updates using CVS (Example 3-1) more difficult in the - future. -

3.2. User Administration

3.2.1. Creating the Default User

When you first run checksetup.pl after installing Bugzilla, it - will prompt you for the administrative username (email address) and - password for this "super user". If for some reason you delete - the "super user" account, re-running checksetup.pl will again prompt - you for this username and password.

If you wish to add more administrative users, add them to - the "admin" group and, optionally, add edit the tweakparams, editusers, - creategroups, editcomponents, and editkeywords groups to add the - entire admin group to those groups. -

3.2.2. Managing Other Users

3.2.2.1. Creating new users

Your users can create their own user accounts by clicking the - "New Account" link at the bottom of each page (assuming they - aren't logged in as someone else already.) However, should you - desire to create user accounts ahead of time, here is how you do - it.

  1. After logging in, click the "Users" link at the footer of - the query page, and then click "Add a new user".

  2. Fill out the form presented. This page is self-explanatory. - When done, click "Submit".

    Adding a user this way will - not - - send an email informing them of their username and password. - While useful for creating dummy accounts (watchers which - shuttle mail to another system, for instance, or email - addresses which are a mailing list), in general it is - preferable to log out and use the - "New Account" - - button to create users, as it will pre-populate all the - required fields and also notify the user of her account name - and password.

3.2.2.2. Modifying Users

To see a specific user, search for their login name - in the box provided on the "Edit Users" page. To see all users, - leave the box blank.

You can search in different ways the listbox to the right - of the text entry box. You can match by - case-insensitive substring (the default), - regular expression, or a - reverse - regular expression match, which finds every user name which does NOT - match the regular expression. (Please see - the man regexp - manual page for details on regular expression syntax.) -

Once you have found your user, you can change the following - fields:

  • Login Name: - This is generally the user's full email address. However, if you - have are using the emailsuffix Param, this may just be the user's - login name. Note that users can now change their login names - themselves (to any valid email address.) -

  • Real Name: The user's real name. Note that - Bugzilla does not require this to create an account.

  • Password: - You can change the user's password here. Users can automatically - request a new password, so you shouldn't need to do this often. - If you want to disable an account, see Disable Text below. -

  • Disable Text: - If you type anything in this box, including just a space, the - user is prevented from logging in, or making any changes to - bugs via the web interface. - The HTML you type in this box is presented to the user when - they attempt to perform these actions, and should explain - why the account was disabled. -

    Don't disable all the administrator accounts!

    - -

    The user can still submit bugs via - the e-mail gateway, if you set it up, even if the disabled text - field is filled in. The e-mail gateway should - not - be enabled for secure installations of Bugzilla.

    -

  • <groupname>: - If you have created some groups, e.g. "securitysensitive", then - checkboxes will appear here to allow you to add users to, or - remove them from, these groups. -

  • canconfirm: - This field is only used if you have enabled the "unconfirmed" - status. If you enable this for a user, - that user can then move bugs from "Unconfirmed" to a "Confirmed" - status (e.g.: "New" status).

  • creategroups: - This option will allow a user to create and destroy groups in - Bugzilla.

  • editbugs: - Unless a user has this bit set, they can only edit those bugs - for which they are the assignee or the reporter. Even if this - option is unchecked, users can still add comments to bugs. -

  • editcomponents: - This flag allows a user to create new products and components, - as well as modify and destroy those that have no bugs associated - with them. If a product or component has bugs associated with it, - those bugs must be moved to a different product or component - before Bugzilla will allow them to be destroyed. -

  • editkeywords: - If you use Bugzilla's keyword functionality, enabling this - feature allows a user to create and destroy keywords. As always, - the keywords for existing bugs containing the keyword the user - wishes to destroy must be changed before Bugzilla will allow it - to die.

  • editusers: - This flag allows a user to do what you're doing right now: edit - other users. This will allow those with the right to do so to - remove administrator privileges from other users or grant them to - themselves. Enable with care.

  • tweakparams: - This flag allows a user to change Bugzilla's Params - (using editparams.cgi.)

  • <productname>: - This allows an administrator to specify the products in which - a user can see bugs. The user must still have the - "editbugs" privilege to edit bugs in these products.

5.9. User Preferences

Once you have logged in, you can customise various aspects of - Bugzilla via the "Edit prefs" link in the page footer. - The preferences are split into three tabs:

5.9.1. Account Settings

On this tab, you can change your basic account information, - including your password, email address and real name. For security - reasons, in order to change anything on this page you must type your - current - password into the - "Password" - field at the top of the page. - If you attempt to change your email address, a confirmation - email is sent to both the old and new addresses, with a link to use to - confirm the change. This helps to prevent account hijacking.

5.9.2. Email Settings

On this tab you can reduce or increase the amount of email sent - you from Bugzilla, opting in our out depending on your relationship to - the bug and the change that was made to it. -

You can also do further filtering on the client side by - using the X-Bugzilla-Reason mail header which Bugzilla - adds to all bugmail. This tells you what relationship you have to the - bug in question, - and can be any of Owner, Reporter, QAcontact, CClist, Voter and - WatchingComponent.

By entering user email names, delineated by commas, into the - "Users to watch" text entry box you can receive a copy of all the - bugmail of other users (security settings permitting.) This powerful - functionality enables seamless transitions as developers change - projects or users go on holiday.

The ability to watch other users may not be available in all - Bugzilla installations. If you can't see it, ask your - administrator.

5.9.3. Permissions

This is a purely informative page which outlines your current - permissions on this installation of Bugzilla - what product groups you - are in, and whether you can edit bugs or perform various administration - functions.

Versions are the revisions of the product, such as "Flinders - 3.1", "Flinders 95", and "Flinders 2000". Version is not a multi-select - field; the usual practice is to select the earliest version known to have - the bug. -

To create and edit Versions:

3.7. Voting

Voting allows users to be given a pot of votes which they can allocate - to bugs, to indicate that they'd like them fixed. - This allows developers to gauge - user need for a particular enhancement or bugfix. By allowing bugs with - a certain number of votes to automatically move from "UNCONFIRMED" to - "NEW", users of the bug system can help high-priority bugs garner - attention so they don't sit for a long time awaiting triage.

To modify Voting settings:

  1. Navigate to the "Edit product" screen for the Product you - wish to modify

  2. Maximum Votes per person: - Setting this field to "0" disables voting.

  3. Maximum Votes a person can put on a single - bug: - It should probably be some number lower than the - "Maximum votes per person". Don't set this field to "0" if - "Maximum votes per person" is non-zero; that doesn't make - any sense.

  4. Number of votes a bug in this product needs to - automatically get out of the UNCONFIRMED state: - Setting this field to "0" disables the automatic move of - bugs from UNCONFIRMED to NEW. -

  5. Once you have adjusted the values to your preference, click - "Update".
