    Or, I just got this cool thing installed.  Now what the heck do I

  <para>
    So you followed the installation instructions to the letter, and
    just logged into bugzilla with your super-duper god account and
    you are sitting at the query screen. Yet, you have nothing to
    query. Your first act of business needs to be to setup the
    operating parameters for bugzilla.

    <title>Post-Installation Checklist</title>
    <para>
      After installation, follow the checklist below to ensure that
      you have a successful installation. If you do not see a
      recommended setting for a parameter, consider leaving it at the
      default while you perform your initial tests on your Bugzilla
      setup.

    <procedure>
      <step>
	<para>
	  Bring up "editparams.cgi" in your web browser.  For
	  instance, to edit parameters at mozilla.org, the URL would
	  be <ulink url="http://bugzilla.mozilla.org/editparams.cgi">
	    http://bugzilla.mozilla.org/editparams.cgi</ulink>, also
	  available under the "edit parameters" link on your query
	  page.
	</para>
      </step>
      <step>
	<para>
	  Set "maintainer" to <emphasis>your</emphasis> email address.
	  This allows Bugzilla's error messages to display your email
	  address and allow people to contact you for help.
	</para>
      </step>
      <step>
	<para>
	  Set "urlbase" to the URL reference for your Bugzilla
	  installation. If your bugzilla query page is at
	  http://www.foo.com/bugzilla/query.cgi, your url base is
	  http://www.foo.com/bugzilla/
	</para>
      </step>
      <step>
	<para>
	  Set "usebuggroups" to "on" <emphasis>only</emphasis> if you
	  need to restrict access to products. I suggest leaving this
	  parameter <emphasis>off</emphasis> while initially testing
	  your Bugzilla.
	</para>
      </step>
      <step>
	<para>
	  Set "usebuggroupsentry" to "on" if you want to restrict
	  access to products. Once again, if you are simply testing
	  your installation, I suggest against turning this parameter
	  on; the strict security checking may stop you from being
	  able to modify your new entries.
	</para>
      </step>
      <step>
        <para>
	  Set "shadowdb" to "bug_shadowdb" if you will be running a
	  *very* large installation of Bugzilla. The shadow database
	  enables many simultaneous users to read and write to the
	  database without interfering with one another.  
	  <note>
	    <para>
	      Enabling "shadowdb" can adversely affect the stability
	      of your installation of Bugzilla. You may frequently
	      need to manually synchronize your databases, or schedule
	      nightly syncs via "cron"
	    </para>
	  </note> Once again, in testing you should avoid this option
	  -- use it if or when you <emphasis>need</emphasis> to use
	  it, and have repeatedly run into the problem it was designed
	  to solve -- very long wait times while attempting to commit
	  a change to the database.
        </para>
	<para>
	  If you use the "shadowdb" option, it is only natural that
	  you should turn the "queryagainstshadowdb" option "On" as
	  well.  Otherwise you are replicating data into a shadow
	  database for no reason!
	</para>
      </step>
      <step>
        <para>
	  If you have custom logos or HTML you must put in place to
	  fit within your site design guidelines, place the code in
	  the "headerhtml", "footerhtml", "errorhtml", "bannerhtml",
	  or "blurbhtml" text boxes.
	  <note>
	    <para>
	      The "headerhtml" text box is the HTML printed out
	      <emphasis>before</emphasis> any other code on the page.
	      If you have a special banner, put the code for it in
	      "bannerhtml". You may want to leave these settings at
	      the defaults initially.
	    </para>
	  </note>
	</para>
      </step>
      <step>
        <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>
	  Ensure "newemailtech" is "on". Your users will thank you.
	  This is the default in the post-2.12 world, and is only an
	  issue if you are upgrading.

      <step>
	<para>
	  Do you want to use the QA Contact ("useqacontact") and
	  status whiteboard ("usestatuswhiteboard") fields? These
	  fields are useful because they allow for more flexibility,
	  particularly when you have an existing Quality Assurance
	  and/or Release Engineering team,  but they may not be needed
	  for smaller installations.
	</para>
      </step>
      <step>
	<para>
	  Set "whinedays" to the amount 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".
	</para>
      </step>
      <step>
	<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.
	  <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!)

	  Set "supportwatchers" to "On".  This feature is helpful for
	  team leads to monitor progress in their respective areas,

	  requiring her to change all the information in the bug.

	      associated with it, those bugs must be moved to a
	      different product or component before Bugzilla will
	      allow them to be destroyed.  The name of a product or
	      component can be changed without affecting the
	      associated bugs, but it tends to annoy the hell out of

	      <emphasis>Editkeywords</emphasis>: If you use Bugzilla's

	      keywords for existing bugs containing the keyword the
	      user wishes to destroy must be changed before Bugzilla
	      will allow it to die. You must be very careful about
	      creating too many new keywords if you run a very large
	      Bugzilla installation; keywords are global variables
	      across products, and you can often run into a phenomenon
	      called "keyword bloat". This confuses users, and then
	      the feature goes unused.
	    </para>
	  </listitem>
	  <listitem>
	    <para>
	      <emphasis>Editusers</emphasis>: This flag allows a user
	      do what you're doing right now: edit other users. This
	      will allow those with the right to do so to remove
	      administrator priveleges from other users or grant them
	      to themselves.  Enable with care.

	  </listitem>
	  <listitem>
	    <para>
	      <emphasis>PRODUCT</emphasis>: PRODUCT bugs access.  This
	      allows an administrator, with product-level granularity,
	      to specify in which products a user can edit bugs.  The
	      user must still have the "editbugs" privelege to edit
	      bugs in this area; this simply restricts them from even
	      seeing bugs outside these boundaries if the
	      administrator has enabled the group sentry parameter
	      "usebuggroupsentry".  Unless you are using bug groups,
	      this option has no effect.

	</example> Each component has a owner and (if you turned it on

      <title>Voting</title>
      <para>
	The concept of "voting" is a poorly understood, yet powerful
	feature for the management of open-source projects.  Each user
	is assigned so many Votes per product, which they can freely
	reassign (or assign multiple votes to a single bug). 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>
      <para>
	The daunting challenge of Votes is deciding where you draw the
	line for a "vocal majority".  If you only have a user base of
	100 users, setting a low threshold for bugs to move from
	UNCONFIRMED to NEW makes sense.  As the Bugzilla user base
	expands, however, these thresholds must be re-evaluated.  You
	should gauge whether this feature is worth the time and close
	monitoring involved, and perhaps forego implementation until
	you have a critical mass of users who demand it.

    <section id="groups">
      <title>Groups and Group Security</title>
      <para>
	Groups can be very useful in bugzilla, because they allow
	users to isolate bugs or products that should only be seen by
	certain people.  Groups can also be a complicated minefield of
	interdependencies and weirdness if mismanaged.

	<example>
	  <title>When to Use Group Security</title>
	  <informalexample>
	    <para>
	      Many Bugzilla sites isolate "Security-related" bugs from
	      all other bugs. This way, they can have a fix ready
	      before the security vulnerability is announced to the
	      world.  You can create a "Security" product which, by
	      default, has no members, and only add members to the
	      group (in their individual User page, as described under
	      User Administration) who should have priveleged access
	      to "Security" bugs.  Alternately, you may create a Group
	      independently of any Product, and change the Group mask
	      on individual bugs to restrict access to members only of
	      certain Groups.
	    </para>
	  </informalexample>
	</example> Groups only work if you enable the "usebuggroups"
	paramater. In addition, if the "usebuggroupsentry" parameter
	is "On", one can restrict access to products by groups, so
	that only members of a product group are able to view bugs
	within that product. Group security in Bugzilla can be divided
	into two categories: Generic and Product-Based.
      </para>
      <note>
	<para>
	  Groups in Bugzilla are a complicated beast that evolved out
	  of very simple user permission bitmasks, apparently itself
	  derived from common concepts in UNIX access controls.  A
	  "bitmask" is a fixed-length number whose value can describe
	  one, and only one, set of states.  For instance, UNIX file
	  permissions are assigned bitmask values:  "execute" has a
	  value of 1, "write" has a value of 2,  and "read" has a
	  value of 4.  Add them together, and a file can be read,
	  written to, and executed if it has a bitmask of "7". (This
	  is a simplified example -- anybody who knows UNIX security
	  knows there is much more to it than this.  Please bear with
	  me for the purpose of this note.)  The only way a bitmask
	  scheme can work is by doubling the bit count for each value.
	  Thus if UNIX wanted to offer another file permission, the
	  next would have to be a value of 8, then the next 16, the
	  next 32, etc.
	</para>
	<para>
	  Similarly, Bugzilla offers a bitmask to define group
	  permissions, with an internal limit of 64.  Several are
	  already occupied by built-in permissions.  The way around
	  this limitation is to avoid assigning groups to products if
	  you have many products, avoid bloating of group lists, and
	  religiously prune irrelevant groups.  In reality, most
	  installations of Bugzilla support far fewer than 64 groups,
	  so this limitation has not hit for most sites, but it is on
	  the table to be revised for Bugzilla 3.0 because it
	  interferes with the security schemes of some administrators.
