>&#13;      Although the Bugzilla development team has taken great care to
      ensure that all easily-exploitable bugs or options are
      documented or fixed in the code, security holes surely exist.
      Great care should be taken both in the installation and usage of
      this software. Carefully consider the implications of installing
      other network services with Bugzilla.  The Bugzilla development
      team members, Netscape Communications, America Online Inc., and
      any affiliated developers or sponsors assume no liability for
      your use of this product.  You have the source code to this

      your security needs are met.

>2.1. What is Bugzilla?</H1
><P
>&#13;    Bugzilla is a bug- or issue-tracking system. Bug-tracking
    systems allow individual or groups of developers effectively to keep track
    of outstanding problems with their product. 
    Bugzilla was originally
    written by Terry Weissman in a programming language called TCL, to
    replace a rudimentary 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.

>2.2. Why Should We Use Bugzilla?</H1
><P
>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.</P
><P
>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.</P
><P
>But why should 
    <EM
>you</EM
>

    use Bugzilla?</P
><P
>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, NASA, Linux-Mandrake, and VA Systems.
    Combined with systems such as

>Perforce SCM</A

    provides a powerful, easy-to-use solution to configuration management and
    replication problems.</P
><P
>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 
    <EM
>something</EM
>
    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  follow the discussion trail 
    that led to critical decisions.</P

>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.</P

>&#13;      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.
      </P
><P
>Using LDAP for Bugzilla authentication requires the 
      Mozilla::LDAP (aka PerLDAP) Perl module. The
      Mozilla::LDAP module in turn requires Netscape's Directory SDK for C.
      After you have installed the SDK, then install the PerLDAP module.
      Mozilla::LDAP and the Directory SDK for C are both

      </P
><P
>&#13;      Set the Param 'useLDAP' to "On" **only** if you will be using an LDAP
      directory for
      authentication. Be very careful when setting up this parameter; if you
      set LDAP authentication, but do not have a valid LDAP directory set up,
      you will not be able to log back in to Bugzilla once you log out. (If
      this happens, you can get back in by manually editing the data/params
      file, and setting useLDAP back to 0.)
      </P
><P
>If using LDAP, you must set the
      three additional parameters: Set LDAPserver to the name (and optionally
      port) of your LDAP server. If no port is specified, it defaults to the
      default port of 389. (e.g "ldap.mycompany.com" or
      "ldap.mycompany.com:1234") Set LDAPBaseDN to the base DN for searching
      for users in your LDAP directory. (e.g. "ou=People,o=MyCompany") uids
      must be unique under the DN specified here. Set LDAPmailattribute to
      the name of the attribute in your LDAP directory which contains the
      primary email address. On most directory servers available, this is
      "mail", but you may need to change this.

>It is possible for a Bugzilla to execute malicious Javascript
      code. Due to internationalization concerns, we are unable to
      incorporate the code changes necessary to fulfill the CERT advisory
      requirements mentioned in

      Executing the following code snippet from a UNIX command shell will
      rectify the problem if your Bugzilla installation is intended for an
      English-speaking audience. As always, be sure your Bugzilla
      installation has a good backup before making changes, and I recommend
      you understand what the script is doing before executing it.</P

      and /usr/local/include. Because of these changed locations for the

      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

        Bugzilla products can have a group associated with them, so that

CLASS="command"
>shadowdb</B
>:
        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</P
><P
>The <SPAN
CLASS="QUOTE"
>"shadowdb"</SPAN
>
        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.</P
><P
>&#13;        As a guide, mozilla.org began needing 
        <SPAN
CLASS="QUOTE"
>"shadowdb"</SPAN
>
        when they reached around 40,000 Bugzilla users with several hundred
        Bugzilla bug changes and comments per day.</P
><P
>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.</P

        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.

>5.7.1. What to Edit</H2
><P
>&#13;        There are two different ways of editing of Bugzilla's templates,
        and which you use depends mainly on how you upgrade Bugzilla. The
        template directory structure is that there's a top level directory,
        <TT
CLASS="filename"
>template</TT
>, which contains a directory for
        each installed localization. The default English templates are
        therefore in <TT
CLASS="filename"
>en</TT
>. Underneath that, there
        is the <TT
CLASS="filename"
>default</TT
> directory and optionally the 
        <TT
CLASS="filename"
>custom</TT
> directory. The <TT
CLASS="filename"
>default</TT
>
        directory contains all the templates shipped with Bugzilla, whereas
        the <TT
CLASS="filename"
>custom</TT
> directory does not exist at first and
        must be created if you want to use it.
      </P
><P
>&#13;        The first method of making customizations is to directly edit the
        templates in <TT
CLASS="filename"
>template/en/default</TT
>. 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
        <B
CLASS="command"
>cvs update</B
>, any template fixes will get
        automagically merged into your modified versions.
      </P
><P
>&#13;        If you use this method, your installation will break if CVS conflicts
        occur.
      </P
><P
>&#13;        The other method is to copy the templates into a mirrored directory
        structure under <TT
CLASS="filename"
>template/en/custom</TT
>.  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.
      </P
><P
>&#13;        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.

>5.7.2. How To Edit Templates</H2
><P
>&#13;        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
        <A
HREF="http://www.template-toolkit.org"
TARGET="_top"
>Template Toolkit home
        page</A
>. However, you should particularly remember (for security
        reasons) to always HTML filter things which come from the database or
        user input, to prevent cross-site scripting attacks.
      </P
><P
>&#13;        However, 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 &#60;, and the data was not intended to be HTML, they need to be
        converted to entity form, ie &#38;lt;.  You use the 'html' filter in the
        Template Toolkit to do this.  If you fail to do this, you may open up
        your installation to cross-site scripting attacks.
      </P
><P
>&#13;        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 &#38;, 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.
      </P
><P
>&#13;        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.

>5.7.3. Template Formats</H2
><P
>&#13;        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 <TT
CLASS="filename"
>&#38;format=simple</TT
> to a buglist.cgi
        URL on your Bugzilla installation.) This
        mechanism, called template 'formats', is extensible.
      </P
><P
>&#13;        To see if a CGI supports multiple output formats, grep the
        CGI for "ValidateOutputFormat". If it's not present, adding
        multiple format support isn't too hard - see how it's done in
        other CGIs.
      </P
><P
>&#13;        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. 
      </P
><P
>&#13;        Write your template in whatever markup or text style is appropriate.
      </P
><P
>&#13;        You now need to decide what content type you want your template
        served as. Open up the <TT
CLASS="filename"
>localconfig</TT
> file and find the 
        <TT
CLASS="filename"
>$contenttypes</TT
>
        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.
      </P
><P
>&#13;        Save the template as <TT
CLASS="filename"
>&#60;stubname&#62;-&#60;formatname&#62;.&#60;contenttypetag&#62;.tmpl</TT

        Try out the template by calling the CGI as

>5.7.4. Particular Templates</H2
><P
>&#13;        There are a few templates you may be particularly interested in
        customizing for your installation.
      </P
><P
>&#13;        <B
CLASS="command"
>index.html.tmpl</B
>:
        This is the Bugzilla front page.
      </P
><P
>&#13;        <B
CLASS="command"
>global/header.html.tmpl</B
>:
        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.
      </P
><P
>&#13;        <B
CLASS="command"
>global/banner.html.tmpl</B
>:
        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.
      </P
><P
>&#13;        <B
CLASS="command"
>global/footer.html.tmpl</B
>:
        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.
      </P
><P
>&#13;        <B
CLASS="command"
>bug/create/user-message.html.tmpl</B
>:
        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.
      </P
><P
>&#13;        <B
CLASS="command"
>bug/process/midair.html.tmpl</B
>:
        This is the page used if two people submit simultaneous changes to the
        same bug.  The second person to submit their changes will get this page
        to tell them what the first person did, and ask if they wish to
        overwrite those changes or go back and revisit the bug.  The default
        title and header on this page read "Mid-air collision detected!"  If
        you work in the aviation industry, or other environment where this
        might be found offensive (yes, we have true stories of this happening)
        you'll want to change this to something more appropriate for your
        environment.
      </P
><P
>&#13;        <B
CLASS="command"
>bug/create/create.html.tmpl</B
> and
        <B
CLASS="command"
>bug/create/comment.txt.tmpl</B
>:
        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 
        <A
HREF="http://bugzilla.mozilla.org/enter_bug.cgi?format=guided"
TARGET="_top"
>guided 
        bug submission form</A
>.
      </P
><P
>&#13;        To make this work, create a custom template for 
        <TT
CLASS="filename"
>enter_bug.cgi</TT
> (the default template, on which you
        could base it, is <TT
CLASS="filename"
>create.html.tmpl</TT
>),
        and either call it <TT
CLASS="filename"
>create.html.tmpl</TT
> or use a format and
        call it <TT
CLASS="filename"
>create-&#60;formatname&#62;.html.tmpl</TT
>.
        Put it in the <TT
CLASS="filename"
>custom/bug/create</TT
>
        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.
      </P
><P
>&#13;        Then, create a template like 
        <TT
CLASS="filename"
>custom/bug/create/comment.txt.tmpl</TT
>, 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.
      </P
><P
>&#13;        For example, if your enter_bug template had a field
        <TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
>&#60;input type="text" name="buildid" size="30"&#62;</PRE
></FONT
></TD
></TR
></TABLE
>
        and then your comment.txt.tmpl had
        <TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
>BuildID: [% form.buildid %]</PRE

        then
        <TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT

>&#13;        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 to it, you may have

>&#13;      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.
    </P
><P
>&#13;      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 
      <TT
CLASS="filename"
>CheckCanChangeField()</TT
>,
      and is found in <TT
CLASS="filename"
>process_bug.cgi</TT
> in your 
      Bugzilla directory. If you open that file and grep for 
      "sub CheckCanChangeField", you'll find it.
    </P
><P
>&#13;      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:
      <TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
>    # Allow the owner to change anything.
    if ($ownerid eq $whoid) {
        return 1;
    }</PRE
></FONT
></TD
></TR
></TABLE
>
      It's fairly obvious what this piece of code does.
    </P
><P
>&#13;      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.
    </P
><P
>&#13;      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 
      $ownerid has been obtained from the database. You can either add a
      positive check, which returns 1 (allow) if certain conditions are true,
      or a negative check, which returns 0 (deny.) E.g.:
      <TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
>    if ($field eq "qacontact") {
        if (UserInGroup("quality_assurance")) {
            return 1;
        } 
        else {
            return 0;
        }
    }</PRE
></FONT
></TD
></TR
></TABLE
>
      This says that only users in the group "quality_assurance" can change
      the QA Contact field of a bug. Getting more weird:
      <TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
>    if (($field eq "priority") &#38;&#38;
        ($vars-&#62;{'user'}{'login'} =~ /.*\@example\.com$/))
    {
        if ($oldvalue eq "P1") {
            return 1;
        } 
        else {
            return 0;
        }
    }</PRE
></FONT
></TD
></TR
></TABLE
>
      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.

>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 (for minor
      spelling fixes and the like). It is also theorectically 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.

	    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.

	    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.

            MySQL was originally chosen because it is free, easy to install,

            Bugzilla used to have the path to perl on the shebang line set to
            <TT
CLASS="filename"
>/usr/bonsaitools/bin/perl</TT
> 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 <TT
CLASS="filename"
>/usr/bin/perl</TT
>.  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

            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 spread-sheet applications.
          </P

            <TT

> to the URL.  RDF
            is meant to be machine readable and thus it is assumed that the

            link to this format.

	    Yes.  However, commits to the database must wait

	    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 &#38; customization.

	    The Bugzilla code has undergone a reasonably complete security audit,

	    it is recommended that you closely examine permissions on your Bugzilla
	    installation, and follow the recommended security guidelines found

            Red Hat's old version of Bugzilla (based on 2.8) worked on Oracle.

	     There is no facility in Bugzilla itself to do this. It's also generally

	    However, if you understand SQL you can use the <B

	    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

	    Well, you can synchronize or you can move bugs.  Synchronization will

	    The most likely cause is a very old browser or a browser that is

	    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.

>B.2. MySQL Bugzilla Database Introduction</H1
><P
>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.</P
><P
>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.</P
><P
>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.</P
><P
>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!</P
><P
>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'.</P
><P
>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."</P
><P
>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...</P
><P
>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!</P

&nbsp;&nbsp;Ahh,&nbsp;so&nbsp;you're&nbsp;wondering&nbsp;just&nbsp;what&nbsp;to&nbsp;do&nbsp;with&nbsp;the&nbsp;information&nbsp;above?&nbsp;&nbsp;At&nbsp;the<br>
mysql&nbsp;prompt,&nbsp;you&nbsp;can&nbsp;view&nbsp;any&nbsp;information&nbsp;about&nbsp;the&nbsp;columns&nbsp;in&nbsp;a&nbsp;table&nbsp;with<br>
this&nbsp;command&nbsp;(where&nbsp;"table"&nbsp;is&nbsp;the&nbsp;name&nbsp;of&nbsp;the&nbsp;table&nbsp;you&nbsp;wish&nbsp;to&nbsp;view):<br>
<br>
mysql&#62;&nbsp;show&nbsp;columns&nbsp;from&nbsp;table;<br>
<br>
&nbsp;&nbsp;You&nbsp;can&nbsp;also&nbsp;view&nbsp;all&nbsp;the&nbsp;data&nbsp;in&nbsp;a&nbsp;table&nbsp;with&nbsp;this&nbsp;command:<br>
<br>
mysql&#62;&nbsp;select&nbsp;*&nbsp;from&nbsp;table;<br>
<br>
&nbsp;&nbsp;--&nbsp;note:&nbsp;this&nbsp;is&nbsp;a&nbsp;very&nbsp;bad&nbsp;idea&nbsp;to&nbsp;do&nbsp;on,&nbsp;for&nbsp;instance,&nbsp;the&nbsp;"bugs"&nbsp;table&nbsp;if<br>
you&nbsp;have&nbsp;50,000&nbsp;bugs.&nbsp;&nbsp;You'll&nbsp;be&nbsp;sitting&nbsp;there&nbsp;a&nbsp;while&nbsp;until&nbsp;you&nbsp;ctrl-c&nbsp;or<br>
50,000&nbsp;bugs&nbsp;play&nbsp;across&nbsp;your&nbsp;screen.<br>
<br>
&nbsp;&nbsp;You&nbsp;can&nbsp;limit&nbsp;the&nbsp;display&nbsp;from&nbsp;above&nbsp;a&nbsp;little&nbsp;with&nbsp;the&nbsp;command,&nbsp;where<br>
"column"&nbsp;is&nbsp;the&nbsp;name&nbsp;of&nbsp;the&nbsp;column&nbsp;for&nbsp;which&nbsp;you&nbsp;wish&nbsp;to&nbsp;restrict&nbsp;information:<br>
<br>
mysql&#62;&nbsp;select&nbsp;*&nbsp;from&nbsp;table&nbsp;where&nbsp;(column&nbsp;=&nbsp;"some&nbsp;info");<br>

&nbsp;&nbsp;--&nbsp;or&nbsp;the&nbsp;reverse&nbsp;of&nbsp;this<br>
<br>
mysql&#62;&nbsp;select&nbsp;*&nbsp;from&nbsp;table&nbsp;where&nbsp;(column&nbsp;!=&nbsp;"some&nbsp;info");<br>
<br>
&nbsp;&nbsp;Let's&nbsp;take&nbsp;our&nbsp;example&nbsp;from&nbsp;the&nbsp;introduction,&nbsp;and&nbsp;assume&nbsp;you&nbsp;need&nbsp;to&nbsp;change<br>
the&nbsp;word&nbsp;"verified"&nbsp;to&nbsp;"approved"&nbsp;in&nbsp;the&nbsp;resolution&nbsp;field.&nbsp;&nbsp;We&nbsp;know&nbsp;from&nbsp;the<br>
above&nbsp;information&nbsp;that&nbsp;the&nbsp;resolution&nbsp;is&nbsp;likely&nbsp;to&nbsp;be&nbsp;stored&nbsp;in&nbsp;the&nbsp;"bugs"<br>
table.&nbsp;Note&nbsp;we'll&nbsp;need&nbsp;to&nbsp;change&nbsp;a&nbsp;little&nbsp;perl&nbsp;code&nbsp;as&nbsp;well&nbsp;as&nbsp;this&nbsp;database<br>
change,&nbsp;but&nbsp;I&nbsp;won't&nbsp;plunge&nbsp;into&nbsp;that&nbsp;in&nbsp;this&nbsp;document.&nbsp;Let's&nbsp;verify&nbsp;the<br>
information&nbsp;is&nbsp;stored&nbsp;in&nbsp;the&nbsp;"bugs"&nbsp;table:<br>
<br>
mysql&#62;&nbsp;show&nbsp;columns&nbsp;from&nbsp;bugs<br>
<br>
&nbsp;&nbsp;(exceedingly&nbsp;long&nbsp;output&nbsp;truncated&nbsp;here)<br>
|&nbsp;bug_status|&nbsp;enum('UNCONFIRMED','NEW','ASSIGNED','REOPENED','RESOLVED','VERIFIED','CLOSED')||MUL&nbsp;|&nbsp;UNCONFIRMED||<br>
<br>
&nbsp;&nbsp;Sorry&nbsp;about&nbsp;that&nbsp;long&nbsp;line.&nbsp;&nbsp;We&nbsp;see&nbsp;from&nbsp;this&nbsp;that&nbsp;the&nbsp;"bug&nbsp;status"&nbsp;column&nbsp;is<br>
an&nbsp;"enum&nbsp;field",&nbsp;which&nbsp;is&nbsp;a&nbsp;MySQL&nbsp;peculiarity&nbsp;where&nbsp;a&nbsp;string&nbsp;type&nbsp;field&nbsp;can<br>
only&nbsp;have&nbsp;certain&nbsp;types&nbsp;of&nbsp;entries.&nbsp;&nbsp;While&nbsp;I&nbsp;think&nbsp;this&nbsp;is&nbsp;very&nbsp;cool,&nbsp;it's&nbsp;not<br>
standard&nbsp;SQL.&nbsp;&nbsp;Anyway,&nbsp;we&nbsp;need&nbsp;to&nbsp;add&nbsp;the&nbsp;possible&nbsp;enum&nbsp;field&nbsp;entry<br>
'APPROVED'&nbsp;by&nbsp;altering&nbsp;the&nbsp;"bugs"&nbsp;table.<br>
<br>
mysql&#62;&nbsp;ALTER&nbsp;table&nbsp;bugs&nbsp;CHANGE&nbsp;bug_status&nbsp;bug_status<br>
&nbsp;&nbsp;&nbsp;&nbsp;-&#62;&nbsp;enum("UNCONFIRMED",&nbsp;"NEW",&nbsp;"ASSIGNED",&nbsp;"REOPENED",&nbsp;"RESOLVED",<br>
&nbsp;&nbsp;&nbsp;&nbsp;-&#62;&nbsp;"VERIFIED",&nbsp;"APPROVED",&nbsp;"CLOSED")&nbsp;not&nbsp;null;<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;(note&nbsp;we&nbsp;can&nbsp;take&nbsp;three&nbsp;lines&nbsp;or&nbsp;more&nbsp;--&nbsp;whatever&nbsp;you&nbsp;put&nbsp;in&nbsp;before&nbsp;the<br>
semicolon&nbsp;is&nbsp;evaluated&nbsp;as&nbsp;a&nbsp;single&nbsp;expression)<br>
<br>
Now&nbsp;if&nbsp;you&nbsp;do&nbsp;this:<br>
<br>
mysql&#62;&nbsp;show&nbsp;columns&nbsp;from&nbsp;bugs;<br>
<br>
&nbsp;&nbsp;you'll&nbsp;see&nbsp;that&nbsp;the&nbsp;bug_status&nbsp;field&nbsp;has&nbsp;an&nbsp;extra&nbsp;"APPROVED"&nbsp;enum&nbsp;that's<br>
available!&nbsp;&nbsp;Cool&nbsp;thing,&nbsp;too,&nbsp;is&nbsp;that&nbsp;this&nbsp;is&nbsp;reflected&nbsp;on&nbsp;your&nbsp;query&nbsp;page&nbsp;as<br>
well&nbsp;--&nbsp;you&nbsp;can&nbsp;query&nbsp;by&nbsp;the&nbsp;new&nbsp;status.&nbsp;&nbsp;But&nbsp;how's&nbsp;it&nbsp;fit&nbsp;into&nbsp;the&nbsp;existing<br>
scheme&nbsp;of&nbsp;things?<br>
&nbsp;&nbsp;Looks&nbsp;like&nbsp;you&nbsp;need&nbsp;to&nbsp;go&nbsp;back&nbsp;and&nbsp;look&nbsp;for&nbsp;instances&nbsp;of&nbsp;the&nbsp;word&nbsp;"verified"<br>
in&nbsp;the&nbsp;perl&nbsp;code&nbsp;for&nbsp;Bugzilla&nbsp;--&nbsp;wherever&nbsp;you&nbsp;find&nbsp;"verified",&nbsp;change&nbsp;it&nbsp;to<br>
"approved"&nbsp;and&nbsp;you're&nbsp;in&nbsp;business&nbsp;(make&nbsp;sure&nbsp;that's&nbsp;a&nbsp;case-insensitive&nbsp;search).<br>
Although&nbsp;you&nbsp;can&nbsp;query&nbsp;by&nbsp;the&nbsp;enum&nbsp;field,&nbsp;you&nbsp;can't&nbsp;give&nbsp;something&nbsp;a&nbsp;status<br>
of&nbsp;"APPROVED"&nbsp;until&nbsp;you&nbsp;make&nbsp;the&nbsp;perl&nbsp;changes.&nbsp;&nbsp;&nbsp;Note&nbsp;that&nbsp;this&nbsp;change&nbsp;I<br>
mentioned&nbsp;can&nbsp;also&nbsp;be&nbsp;done&nbsp;by&nbsp;editing&nbsp;checksetup.pl,&nbsp;which&nbsp;automates&nbsp;a&nbsp;lot&nbsp;of<br>
this.&nbsp;&nbsp;But&nbsp;you&nbsp;need&nbsp;to&nbsp;know&nbsp;this&nbsp;stuff&nbsp;anyway,&nbsp;right?<br>

    command line. They live in the 
    <TT
CLASS="filename"
>contrib/cmdline</TT
> 
    directory. However, they
    have not yet been updated to work with 2.16 (post-templatisation.).
    There are three files - <TT
CLASS="filename"

    <TT
CLASS="filename"
>buglist</TT
> and <TT
CLASS="filename"
>bugs</TT

><TT
CLASS="filename"

> 
    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".</P
><P
><TT
CLASS="filename"
>buglist</TT
>
    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=".</P
><P
>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.</P
><P
><TT
CLASS="filename"
>bugs</TT
> is a simple shell script which calls
    <TT
CLASS="filename"
>buglist</TT
> 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

    back-end is modified to work with PostgreSQL instead of MySQL and they have
    custom templates to get their desired look and feel, but other than that it

    program should come with manuals providing the same freedoms that the
    software does. But this License is not limited to software manuals; it

><P
>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".</P
><P
>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.</P
><P
>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.</P
><P
>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.</P
><P
>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.</P
><P
>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".</P
><P
>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.</P
><P
>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.</P

    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

    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

>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.

          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...
