>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.

NAME="why"
></A
>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

>CVS</A
>, 
    <A
HREF="http://www.mozilla.org/bonsai.html"
TARGET="_top"
>Bonsai</A
>, or 
    <A
HREF="http://www.perforce.com"
TARGET="_top"
>Perforce SCM</A
>, Bugzilla
    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
><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

      in literal HTML tags rather than being interpreted by a browser.
      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
HREF="http://www.bugzilla.org"

      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.

>&#13;      Don't use sigs in comments. Signing your name ("Bill") is acceptable,

>&#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.

      The GD library, which Bugzilla needs to do bug graphs, is one of
      these.</P
><P
>The easiest way to get a lot of these is with a program called
      Fink, which is similar in nature to the CPAN installer, but installs
      common GNU utilities. Fink is available from
      <A

>fink install gd</B

><P
>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 for libgd will be at /sw/lib and /sw/include instead of /usr/lib
      and /usr/local/include. Because of these changed locations for the
      libraries, the Perl GD module will not install directly via CPAN, because it
      looks for the specific paths instead of getting them from your
      environment. But there's a way around that :-)</P

        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 <SPAN
CLASS="QUOTE"

        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

        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.

        Often, administrators will allow users to add themselves to the CC

        comment as to their reasons for the change, yet require that most
        other changes come with an explanation.</P

      Administrators can now configure the look and feel of Bugzilla without

>&#13;      Templatization also makes localized versions of Bugzilla possible, 
      for the first time. In the future, a Bugzilla installation may
      have templates installed for multiple localizations, and select
      which ones to use based on the user's browser language setting.

>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 
        <TT
CLASS="filename"
>&#60;cginame&#62;.cgi?format=&#60;formatname&#62;</TT

>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"

        and then your comment.txt.tmpl had
        <TABLE

>&#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.

>&#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.

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

>These examples also assume that your Bugzilla installation is at
    <TT

    simply substitute the proper paths where appropriate.
