Using Bugzilla
What, Why, How, & Where?
What is Bugzilla?
Bugzilla is one example of a class of programs called "Defect
Tracking Systems", or, more commonly, "Bug-Tracking Systems". Defect
Tracking Systems allow individual or groups of developers to keep
track of outstanding bugs in their product effectively. Bugzilla was
originally written by Terry Weissman in a programming language called
"TCL", to replace a crappy bug-tracking database used internally by
Netscape Communications. Terry later ported Bugzilla to Perl from
TCL, and in Perl it remains to this day. Most commercial
defect-tracking software vendors at the time charged enormous
licensing fees, and Bugzilla quickly became a favorite of the
open-source crowd (with its genesis in the open-source browser
project, Mozilla). It is now the de-facto standard defect-tracking
system against which all others are measured.
Bugzilla has matured immensely, and now boasts many advanced features. These include:
Powerful searching
User-configurable email notifications of bug changes
Full change history
Inter-bug dependency tracking and graphing
Excellent attachment management
Integrated, product-based, granular security schema
Fully security-audited, and runs under Perl's taint mode
A robust, stable RDBMS back-end
Web, XML, email and console interfaces
Completely customisable and/or localisable web user interface
Extensive configurability
Smooth upgrade pathway between versions
Why Should We Use Bugzilla?
No, Who's on first...
For many years, defect-tracking software has remained
principally the domain of large software development houses.
Even then, most shops never bothered with bug-tracking software,
and instead simply relied on shared lists and email to monitor
the status of defects. This procedure is error-prone and tends
to cause those bugs judged least significant by developers to be
dropped or ignored.
These days, many companies are finding that integrated
defect-tracking systems reduce downtime, increase productivity,
and raise customer satisfaction with their systems. Along with
full disclosure, an open bug-tracker allows manufacturers to
keep in touch with their clients and resellers, to communicate
about problems effectively throughout the data management chain.
Many corporations have also discovered that defect-tracking
helps reduce costs by providing IT support accountability,
telephone support knowledge bases, and a common, well-understood
system for accounting for unusual system or software issues.
But why should you use Bugzilla?
Bugzilla is very adaptable to various situations. Known uses
currently include IT support queues, Systems Administration
deployment management, chip design and development problem
tracking (both pre-and-post fabrication), and software and
hardware bug tracking for luminaries such as Redhat, Loki
software, Linux-Mandrake, and VA Systems. Combined with systems
such as CVS, Bonsai, or Perforce SCM, Bugzilla provides a
powerful, easy-to-use solution to configuration management and
replication problems
Bugzilla can dramatically increase the productivity and
accountability of individual employees by providing a documented
workflow and positive feedback for good performance. How many
times do you wake up in the morning, remembering that you were
supposed to do something today, but you
just can't quite remember? Put it in Bugzilla, and you have a
record of it from which you can extrapolate milestones, predict
product versions for integration, and by using Bugzilla's e-mail
integration features be able to follow the discussion trail that
led to critical decisions.
Ultimately, Bugzilla puts the power in your hands to improve
your value to your employer or business while providing a usable
framework for your natural attention to detail and knowledge
store to flourish.
How do I use Bugzilla?
Hey! I'm Woody! Howdy, Howdy, Howdy!
This section contains information for end-users of Bugzilla.
If you are administering a Bugzilla installation, please consult the
Installing and Administering Bugzilla portions of this Guide.
There is a Bugzilla test installation, called
Landfill, which you are welcome to play with.
However, it does not necessarily have all Bugzilla features
enabled, and often runs cutting-edge versions of Bugzilla for
testing, so some things may work slightly differently than
mentioned here.
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.tequilarista.org/bugzilla-tip/
Click the Open a new Bugzilla account
link, enter your
email address and, optionally, your name in the spaces provided,
then click Create Account
.
Within moments, you should receive an email to the address
you provided above, which contains your login name
(generally the same as the email address), and a password
you can use to access your account. This password is
randomly generated, and can be changed to something more memorable.
Click the Log In
link in the yellow area 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 for authentication, so
(unless your IP address changes) you should not have to log in again.
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 names of most fields
are hyperlinks; clicking them will take you to context-sensitive
help on that particular field.
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, including
editcomponents.cgi,
editgroups.cgi,
editkeywords.cgi,
editparams.cgi,
editproducts.cgi,
editusers.cgi,
editversions.cgi, and
sanitycheck.cgi.
Bugzilla-General,
Anything that doesn't fit in the other components, or spans
multiple components.
Creating/Changing Bugs,
Creating, changing, and viewing bugs.
enter_bug.cgi,
post_bug.cgi,
show_bug.cgi and
process_bug.cgi.
Documentation,
The bugzilla documentation, including anything in the
docs/ directory and The Bugzilla Guide
Email,
Anything to do with email sent by Bugzilla.
processmail
Installation,
The installation process of Bugzilla. This includes
checksetup.pl and whatever else it evolves into.
Query/Buglist,
Anything to do with searching for bugs and viewing the buglists.
query.cgi and
buglist.cgi
Reporting/Charting,
Getting reports from Bugzilla.
reports.cgi and
duplicates.cgi
User Accounts,
Anything about managing a user account from the user's perspective.
userprefs.cgi, 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.
Status and Resolution:
A bug passes through several Statuses in its lifetime, and ends up in the
RESOLVED status, with one of a set of Resolutions (e.g. FIXED, INVALID.)
The different possible
values for Status and Resolution on your installation will be documented
in the context-sensitive help for those items.
Assigned To:
The person responsible for fixing the bug.
URL:
A URL associated with the bug, if any.
Summary:
A one-sentence summary of the problem.
Status Whiteboard: (a.k.a. Whiteboard) A
free-form text area for adding short notes and tags to a bug.
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.
Platform and OS:
These indicate the computing environment where the bug was found.
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.
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.
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.
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.
Reporter:
The person who filed the bug.
CC list:
A list of people who get mail when the bug changes.
Attachments:
You can attach files (e.g. testcases or patches) to bugs. If there are
any attachments, they are listed in this section.
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.
Votes:
Whether this bug has any votes.
Additional Comments:
You can add your two cents to the bug discussion here, if you have
something worthwhile to say.
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:
landfill.tequilarista.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. Once you've defined
a search, you can either run it, or save it as a Remembered Query, which
can optionally appear in the footer of your pages.
Highly advanced querying is done using Boolean Charts, which have their
own context-sensitive help.
Bug Lists
If you run a search, a list of matching bugs will be returned.
The default search is to return all open bugs on the system -
don't try running this search on a Bugzilla installation with
a lot of bugs!
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.
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 this query: 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.
Filing Bugs
And all this time, I thought we were taking bugs out...
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:
Go to Landfill
in your browser and click
Enter a new bug report.
Select a product - any one will do.
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.
Select "Commit" and send in your bug report.
Where can I find my user preferences?
Indiana, it feels like we walking on fortune cookies!
These ain't fortune cookies, kid...
Customized User Preferences offer tremendous versatility to your
individual Bugzilla experience. Let's plunge into what you can
do! The first step is to click the "Edit prefs" link at the
footer of each page once you have logged in to Landfill.
Account Settings
On this page, you can change your basic Account Settings,
including your password and full name. For security reasons,
in order to change anything on this page you must type your
current password into the Old
Password
field. If you wish to change your
password, type the new password you want into the New
Password
field and again into the Re-enter
new password
field to ensure you typed your new
password correctly. Select the Submit
button
and you are done.
Email Settings
Email Notification
Here you can reduce or increase the amount of email sent you
from Bugzilla. Although this is referred to as
Advanced Email Filtering Options
, they are,
in fact, the standard email filter set. All of them are
self-explanatory, but you can use the filters in interesting
ways. For instance, some people (notably Quality Assurance
personnel) often only care to receive updates regarding a
bug when the bug changes state, so they can track bugs on
their flow charts and know when it is time to pull the bug
onto a quality assurance platform for inspection. Other
people set up email gateways to
or , and
restrict which types of Bugzilla information are fed to
these systems..
New Email Technology
This option may not be available in all Bugzilla
installations, depending upon the preferences of the
systems administrator responsible for the setup of your
Bugzilla. However, if you really want this functionality,
ask her to "enable newemailtech in Params" and "make it
the default for all new users", referring her to the
Administration section of this Guide.
Disregard the warnings about "experimental and bleeding
edge"; the code to handle email in a cleaner manner than
that historically used for Bugzilla is quite robust and
well-tested now.
I recommend you enable the option, "Click here to sign up
(and risk any bugs)". Your email-box will thank you for it.
The fundamental shift in "newemailtech" is away from
standard UNIX "diff" output, which is quite ugly, to a
prettier, better laid-out email.
"Watching" Users
This option may not be available in all Bugzilla
installations, depending upon the preferences of the
systems administrator responsible for the setup of your
Bugzilla. However, if you really want this functionality,
ask her to "enable watchers in Params".
By entering user email names into the "Users to watch" text
entry box, delineated by commas, you can watch bugs of other
users. This powerful functionality enables seamless
transitions as developers change projects, managers wish to
get in touch with the issues faced by their direct reports,
or users go on vacation. If any of these three situations
apply to you, you will undoubtedly find this feature quite
convenient.
Permissions
This is a purely informative page which outlines your current
permissions on this installation of Bugzilla. If you have
permissions to grant certain permissions to other users, the
"other users" link appears on this page as well as the footer.
For more information regarding user administration, please
consult the Administration section of this Guide.
