    <para>
      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.
    </para>

    <indexterm>

    <procedure>
      <step>
        <para> 
          <command>maintainer</command>:

          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.
        </para>
      </step>

      <step>
        <para>
          <command>urlbase</command>:

          This parameter defines the fully qualified domain name and web 
          server path to your Bugzilla installation.
        </para>

        <para>
          For example, if your Bugzilla query page is
          <filename>http://www.foo.com/bugzilla/query.cgi</filename>, 
          set your <quote>urlbase</quote>
          to <filename>http://www.foo.com/bugzilla/</filename>.
        </para>
      </step>

      <step>
        <para>
          <command>makeproductgroups</command>:

          This dictates whether or not to automatically create groups
          when new products are created.
        </para>
      </step>

      <step>
        <para>
          <command>useentrygroupdefault</command>:

          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 <quote>on</quote>, 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.
        </para>
      </step>

      <step>
        <para>
          <command>shadowdb</command>:

          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.
        </para>

        <para>
          The <quote>shadowdb</quote> 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.
        </para>
        
        <para>
          As a guide, on reasonably old hardware, mozilla.org began needing 
          <quote>shadowdb</quote> when they reached around 40,000 Bugzilla
          users with several hundred Bugzilla bug changes and comments per day.
        </para>

        <para>
          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.
        </para>
      </step>

      <step>
        <para>
          <command>shutdownhtml</command>:

          If you need to shut down Bugzilla to perform administration, enter
          some descriptive text (with embedded HTML codes, if you'd like)
          into this box. Anyone who tries to use Bugzilla (including admins)
          will receive a page displaying this text. Users can neither log in
          nor log out while shutdownhtml is enabled.
        </para>

        <note>
          <para>
            Although regular log-in capability is disabled while 'shutdownhtml'
            is enabled, safeguards are in place to protect the unfortunate 
            admin who loses connection to Bugzilla. Should this happen to you,
            go directly to the <filename>editparams.cgi</filename> (by typing
            the URL in manually, if necessary). Doing this will prompt you to
            log in, and your name/password will be accepted here (but nowhere
            else). 
          </para>
        </note>
      </step>

      <step>
        <para>
          <command>passwordmail</command>:

          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.
        </para>

        <para>
          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.
        </para>
      </step>


      <step>
        <para>
          <command>movebugs</command>:

          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
          <filename>movebugs.pl</filename> in your Bugzilla source tree for
          further documentation, such as it is.
        </para>
      </step>

      <step>
        <para>
          <command>useqacontact</command>:

          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.
        </para>
      </step>

      <step>
        <para>
          <command>usestatuswhiteboard</command>:

          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.         
        </para>
      </step>

      <step>
        <para>
          <command>whinedays</command>:

          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).
        </para>
      </step>

      <step>
        <para>
          <command>commenton*</command>:

          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.
        </para>

        <para>
          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. 
        </para>

        <note>
          <para>
            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!)
          </para>
        </note>
      </step>

      <step>
        <para>
          <command>supportwatchers</command>:

          Turning on this option allows users to ask to receive copies 
          of bug mail sent to another user.  Watching a user with
          different group permissions is not a way to 'get around' the
          system; copied emails are still subject to the normal groupset
          permissions of a bug, and <quote>watchers</quote> will only be 
          copied on emails from bugs they would normally be allowed to view. 
        </para> 
      </step>


      <step>
        <para>
          <command>noresolveonopenblockers</command>:

          This option will prevent users from resolving bugs as FIXED if
          they have unresolved dependencies. Only the FIXED resolution
          is affected. Users will be still able to resolve bugs to
          resolutions other than FIXED if they have unresolved dependent
          bugs.

              <quote>New Account</quote>

              button to create users, as it will pre-populate all the

        leave the box blank.</para>

        <para>You can search in different ways the listbox to the right

        case-insensitive substring (the default),
        regular expression, or a 
        <emphasis>reverse</emphasis>
        regular expression match, which finds every user name which does NOT

    Products</glossterm>

    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...)</para>

    <para>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.</para>

  <section id="components">
    <title>Components</title>

    <para>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.</para>

    <para>
    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 
    <emphasis>default assignments</emphasis>; 
    these can be changed on bug submission, or at any later point in
    a bug's life.</para>

    <para>Versions are the revisions of the product, such as "Flinders

 <section id="flags-overview">
   <title>Flags</title>
   
   <para>
     Flags are a way to attach a specific status to a bug or attachment, 
     either <quote>+</quote> or <quote>-</quote>. The meaning of these symbols depends on the text
     the flag itself, but contextually they could mean pass/fail, 
     accept/reject, approved/denied, or even a simple yes/no. If your site
     allows requestable flags, then users may set a flag to <quote>?</quote> as a 
     request to another user that they look at the bug/attachment, and set
     the flag to its correct status.

            To do this, uncheck <quote>active</quote>. Deactivated
            flags will still show up in the UI if they are ?, +, or -, but they
            may only be cleared (unset), and cannot be changed to a new value.
            Once a deactivated flag is cleared, it will completely disappear from a 
            bug/attachment, and cannot be set again.

    <title>Voting</title>

    <para>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.</para>

  <section id="quips">
    <title>Quips</title>

    <para>
      Quips are small text messages that can be configured to appear
      next to search results. A Bugzilla installation can have its own specific
      quips. Whenever a quip needs to be displayed, a random selection
      is made from the pool of already existing quips.
    </para>
  
    <para>
      Quips are controlled by the <emphasis>enablequips</emphasis> parameter.
      It has several possible values: on, approved, frozen or off.
      In order to enable quips approval you need to set this parameter
      to "approved". In this way, users are free to submit quips for
      addition but an administrator must explicitly approve them before
      they are actually used.
    </para>

    <para>
      In order to see the user interface for the quips, it is enough to click
      on a quip when it is displayed together with the search results. Or
      it can be seen directly in the browser by visiting the quips.cgi URL
      (prefixed with the usual web location of the Bugzilla installation).
      Once the quip interface is displayed, it is enough to click the
      "view and edit the whole quip list" in order to see the administration
      page. A page with all the quips available in the database will
      be displayed.
    </para>

    <para>
      Next to each tip there is a checkbox, under the
      "Approved" column. Quips who have this checkbox checked are
      already approved and will appear next to the search results.
      The ones that have it unchecked are still preserved in the
      database but they will not appear on search results pages.
      User submitted quips have initially the checkbox unchecked.
    </para>
  
    <para>
      Also, there is a delete link next to each quip,
      which can be used in order to permanently delete a quip.
    </para>
  </section>

  <section id="groups">
    <title>Groups and Group Security</title>

    <para>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 <quote>Edit Group Controls.</quote>
    </para>

    <para>
    If the makeproductgroups param is on, a new group will be automatically
    created for every new product. It is primarily available for backward
    compatibility with older sites. 
    </para>
    <para>
      Note that group permissions are such that you need to be a member
      of <emphasis>all</emphasis> the groups a bug is in, for whatever
      reason, to see that bug. Similarly, you must be a member 
      of <emphasis>all</emphasis> of the entry groups for a product 
      to add bugs to a product and you must be a member 
      of <emphasis>all</emphasis> of the canedit groups for a product
      in order to make <emphasis>any</emphasis> change to bugs in that
      product.
    </para>    
    <note>
      <para>
        By default, bugs can also be seen by the Assignee, the Reporter, and 
        by everyone on the CC List, regardless of whether or not the bug would 
        typically be viewable by them. Visibility to the Reporter and CC List can 
        be overridden (on a per-bug basis) by bringing up the bug, finding the 
        section that starts with <quote>Users in the roles selected below...</quote>
        and un-checking the box next to either 'Reporter' or 'CC List' (or both).

    <title>Upgrading to New Releases</title>

    <warning>
      <para>Upgrading is a one-way process. You should backup your database

      to revert to the old Bugzilla version for any reason, you will have to
      restore from these backups.
      </para>
    </warning>

    <para>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.

    </orderedlist>

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

    <para>Revisions are normally released to fix security vulnerabilities
    and are distinguished by an increase in the third number. For example,
    when 2.16.6 was released, it was a revision to 2.16.5.
    </para>

    <para>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, 2.18.0 is a newer point
    release than 2.16.5.
    </para>

    <para>The examples in this section are written as if you were updating
    to version 2.18.1.  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.
    </para>

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

      <title>Upgrading using CVS</title>

      <para>Every release of Bugzilla, whether it is a revision or a point

      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.

      <title>Upgrading using patches</title>

      <para>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.
