Bugzilla is configured by changing various parameters, accessed
from the "Parameters" link in the Administration page (the
Administration page can be found by clicking the "Administration"
link in the footer). The parameters are divided into several categories,
accessed via the menu on the left. Following is a description of the
different categories and important parameters within those categories.
</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-requiredsettings"></a>3.1.1. Required Settings</h3></div></div></div><p>
The core required parameters for any Bugzilla installation are set
here. These parameters must be set before a new Bugzilla installation
can be used. Administrators should review this list before
deploying a new Bugzilla installation.
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term">
maintainer
</span></dt><dd><p>
Email address of the person
responsible for maintaining this Bugzilla installation.
The address need not be that of a valid Bugzilla account.
</p></dd><dt><span class="term">
urlbase
</span></dt><dd><p>
Defines the fully qualified domain name and web
server path to this Bugzilla installation.
</p><p>
For example, if the Bugzilla query page is
<code class="filename">http://www.foo.com/bugzilla/query.cgi</code>,
the <span class="quote">“<span class="quote">urlbase</span>”</span> should be set
to <code class="filename">http://www.foo.com/bugzilla/</code>.
</p></dd><dt><span class="term">
docs_urlbase
</span></dt><dd><p>
Defines path to the Bugzilla documentation. This can be a fully
qualified domain name, or a path relative to "urlbase".
</p><p>
For example, if the "Bugzilla Configuration" page
of the documentation is
<code class="filename">http://www.foo.com/bugzilla/docs/html/parameters.html</code>,
set the <span class="quote">“<span class="quote">docs_urlbase</span>”</span>
to <code class="filename">http://www.foo.com/bugzilla/docs/html/</code>.
</p></dd><dt><span class="term">
sslbase
</span></dt><dd><p>
Defines the fully qualified domain name and web
server path for HTTPS (SSL) connections to this Bugzilla installation.
</p><p>
For example, if the Bugzilla main page is
<code class="filename">https://www.foo.com/bugzilla/index.cgi</code>,
the <span class="quote">“<span class="quote">sslbase</span>”</span> should be set
to <code class="filename">https://www.foo.com/bugzilla/</code>.
</p></dd><dt><span class="term">
ssl_redirect
</span></dt><dd><p>
If enabled, Bugzilla will force HTTPS (SSL) connections, by
automatically redirecting any users who try to use a non-SSL
connection.
</p></dd><dt><span class="term">
cookiedomain
</span></dt><dd><p>
Defines the domain for Bugzilla cookies. This is typically left blank.
If there are multiple hostnames that point to the same webserver, which
require the same cookie, then this parameter can be utilized. For
example, If your website is at
<code class="filename">https://www.foo.com/</code>, setting this to
<code class="filename">.foo.com/</code> will also allow
<code class="filename">bar.foo.com/</code> to access Bugzilla cookies.
</p></dd><dt><span class="term">
cookiepath
</span></dt><dd><p>
Defines a path, relative to the web server root, that Bugzilla
cookies will be restricted to. For example, if the
<span class="command"><strong>urlbase</strong></span> is set to
<code class="filename">http://www.foo.com/bugzilla/</code>, the
<span class="command"><strong>cookiepath</strong></span> should be set to
<code class="filename">/bugzilla/</code>. Setting it to "/" will allow all sites
served by this web server or virtual host to read Bugzilla cookies.
</p></dd><dt><span class="term">
utf8
</span></dt><dd><p>
Determines whether to use UTF-8 (Unicode) encoding for all text in
Bugzilla. New installations should set this to true to avoid character
encoding problems. Existing databases should set this to true only
after the data has been converted from existing legacy character
encoding to UTF-8, using the
<code class="filename">contrib/recode.pl</code> script.

<code class="filename">checksetup.pl</code> immediately afterward.
</p></td></tr></table></div></dd><dt><span class="term">
shutdownhtml
</span></dt><dd><p>
If there is any text in this field, this Bugzilla installation will
be completely disabled and this text will appear instead of all
Bugzilla pages for all users, including Admins. Used in the event
of site maintenance or outage situations.
</p><div class="note" style="margin-left: 1em; margin-right: 1em"><table border="0" summary="Note"><tr><td rowspan="2" align="center" valign="top" width="25"><img alt="[Note]" src="../images/note.gif"></td><th align="left"></th></tr><tr><td align="left" valign="top"><p>
Although regular log-in capability is disabled while
<span class="command"><strong>shutdownhtml</strong></span>
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 <code class="filename">editparams.cgi</code> (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).
</p></td></tr></table></div></dd><dt><span class="term">
announcehtml
</span></dt><dd><p>
Any text in this field will be displayed at the top of every HTML
page in this Bugzilla installation. The text is not wrapped in any
tags. For best results, wrap the text in a <span class="quote">“<span class="quote"><div></span>”</span>
tag. Any style attributes from the CSS can be applied. For example,
to make the text green inside of a red box, add <span class="quote">“<span class="quote">id=message</span>”</span>
to the <span class="quote">“<span class="quote"><div></span>”</span> tag.
</p></dd><dt><span class="term">
proxy_url
</span></dt><dd><p>
If this Bugzilla installation is behind a proxy, enter the proxy
information here to enable Bugzilla to access the Internet. Bugzilla
requires Internet access to utilize the
<span class="command"><strong>upgrade_notification</strong></span> parameter (below). If the
proxy requires authentication, use the syntax:
<code class="filename">http://user:pass@proxy_url/</code>.
</p></dd><dt><span class="term">
upgrade_notification
</span></dt><dd><p>
Enable or disable a notification on the homepage of this Bugzilla
installation when a newer version of Bugzilla is available. This
notification is only visible to administrators. Choose "disabled",
to turn off the notification. Otherwise, choose which version of
Bugzilla you want to be notified about: "development_snapshot" is the
latest release on the trunk; "latest_stable_release" is the most
recent release available on the most recent stable branch;
"stable_branch_release" the most recent release on the branch
this installation is based on.
</p></dd></dl></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-admin-policies"></a>3.1.2. Administrative Policies</h3></div></div></div><p>
This page contains parameters for basic administrative functions.
Options include whether to allow the deletion of bugs and users,
and whether to allow users to change their email address.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-user-authentication"></a>3.1.3. User Authentication</h3></div></div></div><p>
This page contains the settings that control how this Bugzilla
installation will do its authentication. Choose what authentication
mechanism to use (the Bugzilla database, or an external source such
as LDAP), and set basic behavioral parameters. For example, choose
whether to require users to login to browse bugs, the management
of authentication cookies, and the regular expression used to
validate email addresses. Some parameters are highlighted below.
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term">
emailregexp
</span></dt><dd><p>
Defines the regular expression used to validate email addresses
used for login names. The default attempts to match fully
qualified email addresses (i.e. 'user@example.com') in a slightly
more restrictive way than what is allowed in RFC 2822.
Some Bugzilla installations allow only local user names (i.e 'user'
instead of 'user@example.com'). In that case, this parameter
should be used to define the email domain.
</p></dd><dt><span class="term">
emailsuffix
</span></dt><dd><p>
This string is appended to login names when actually sending
email to a user. For example,
If <span class="command"><strong>emailregexp</strong></span> has been set to allow
local usernames,
then this parameter would contain the email domain for all users
(i.e. '@example.com').
</p></dd></dl></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-attachments"></a>3.1.4. Attachments</h3></div></div></div><p>
This page allows for setting restrictions and other parameters
regarding attachments to bugs. For example, control size limitations
and whether to allow pointing to external files via a URI.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-bug-change-policies"></a>3.1.5. Bug Change Policies</h3></div></div></div><p>
Set policy on default behavior for bug change events. For example,
choose which status to set a bug to when it is marked as a duplicate,
and choose whether to allow bug reporters to set the priority or
target milestone. Also allows for configuration of what changes
should require the user to make a comment, described below.
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term">
commenton*
</span></dt><dd><p>
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.
</p><p>
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.
</p><div class="note" style="margin-left: 1em; margin-right: 1em"><table border="0" summary="Note"><tr><td rowspan="2" align="center" valign="top" width="25"><img alt="[Note]" src="../images/note.gif"></td><th align="left"></th></tr><tr><td align="left" valign="top"><p>
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!)
</p></td></tr></table></div></dd><dt><span class="term">
noresolveonopenblockers
</span></dt><dd><p>
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.
</p></dd></dl></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-bugfields"></a>3.1.6. Bug Fields</h3></div></div></div><p>
The parameters in this section determine the default settings of
several Bugzilla fields for new bugs, and also control whether
certain fields are used. For example, choose whether to use the
"target milestone" field or the "status whiteboard" field.
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term">
useqacontact
</span></dt><dd><p>
This allows you to define an email address for each component,
in addition to that of the default assignee, who will be sent
carbon copies of incoming bugs.
</p></dd><dt><span class="term">
usestatuswhiteboard
</span></dt><dd><p>
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.
</p></dd></dl></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-bugmoving"></a>3.1.7. Bug Moving</h3></div></div></div><p>
This page controls whether this Bugzilla installation allows certain
users to move bugs to an external database. If bug moving is enabled,
there are a number of parameters that control bug moving behaviors.
For example, choose which users are allowed to move bugs, the location
of the external database, and the default product and component that
bugs moved <span class="emphasis"><em>from</em></span> other bug databases to this
Bugzilla installation are assigned to.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-dependency-graphs"></a>3.1.8. Dependency Graphs</h3></div></div></div><p>
This page has one parameter that sets the location of a Web Dot
server, or of the Web Dot binary on the local system, that is used
to generate dependency graphs. Web Dot is a CGI program that creates
images from <code class="filename">.dot</code> graphic description files. If
no Web Dot server or binary is specified, then dependency graphs will
be disabled.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-group-security"></a>3.1.9. Group Security</h3></div></div></div><p>
Bugzilla allows for the creation of different groups, with the
ability to restrict the visibility of bugs in a group to a set of
specific users. Specific products can also be associated with
groups, and users restricted to only see products in their groups.
Several parameters are described in more detail below. Most of the
configuration of groups and their relationship to products is done
on the "Groups" and "Product" pages of the "Administration" area.
The options on this page control global default behavior.
For more information on Groups and Group Security, see
<a class="xref" href="groups.html" title="3.15. Groups and Group Security">Section 3.15, “Groups and Group Security”</a>
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term">

Determines whether or not to automatically create groups
when new products are created. If this is on, the groups will be
used for querying bugs.
</p></dd><dt><span class="term">
usevisibilitygroups
</span></dt><dd><p>
If selected, user visibility will be restricted to members of
groups, as selected in the group configuration settings.
Each user-defined group can be allowed to see members of selected
other groups.

authentication architecture. This page contains all the parameters
necessary to configure Bugzilla for use with LDAP authentication.
</p><p>
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 that
require a 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. Bugzilla tries to bind to LDAP using
those credentials and, if successful, tries to map this account to a
Bugzilla account. If an LDAP mail attribute is defined, the value of this
attribute is used, otherwise the "emailsuffix" parameter is appended to LDAP
username to form a full email address. If an account for this address
already exists in the Bugzilla installation, 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. For example, bugs are still assigned by
email address and users are still queried by email address.

receive notification each time a new bug in entered, or when
an existing bug changes, according to the normal groupset
permissions. It may be useful for sending notifications to a
mailing-list, for instance.

This page contains configuration parameters for the CVS server,
Bonsai server and LXR server that Bugzilla will use to enable the
features of the Patch Viewer. Bonsai is a tool that enables queries
to a CVS tree. LXR is a tool that can cross reference and index source
code.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-querydefaults"></a>3.1.14. Query Defaults</h3></div></div></div><p>
This page controls the default behavior of Bugzilla in regards to
several aspects of querying bugs. Options include what the default
query options are, what the "My Bugs" page returns, whether users
can freely add bugs to the quip list, and how many duplicate bugs are
needed to add a bug to the "most frequently reported" list.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="param-shadowdatabase"></a>3.1.15. Shadow Database</h3></div></div></div><p>
This page controls whether a shadow database is used, and all the
parameters associated with the shadow database. Versions of Bugzilla
prior to 3.2 used the MyISAM table type, which supports
only table-level write locking. With MyISAM, any time someone is making a change to
a bug, the entire table is locked until the write operation is complete.
Locking for write also blocks reads until the write is complete.
</p><p>
The <span class="quote">“<span class="quote">shadowdb</span>”</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.
</p><div class="note" style="margin-left: 1em; margin-right: 1em"><table border="0" summary="Note"><tr><td rowspan="2" align="center" valign="top" width="25"><img alt="[Note]" src="../images/note.gif"></td><th align="left"></th></tr><tr><td align="left" valign="top"><p>
As of version 3.2, Bugzilla no longer uses the MyISAM table type.
Instead, InnoDB is used, which can do transaction-based locking.
Therefore, the limitations the Shadow Database feature was designed
to workaround no longer exist.
</p></td></tr></table></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="admin-usermatching"></a>3.1.16. User Matching</h3></div></div></div><p>
The settings on this page control how users are selected and queried
when adding a user to a bug. For example, users need to be selected
when choosing who the bug is assigned to, adding to the CC list or
selecting a QA contact. With the "usemenuforusers" parameter, it is
possible to configure Bugzilla to
display a list of users in the fields instead of an empty text field.
This should only be used in Bugzilla installations with a small number
of users. If users are selected via a text box, this page also
contains parameters for how user names can be queried and matched
when entered.
</p><p>
Another setting called 'ajax_user_autocompletion' enables certain
user fields to display a list of matched user names as a drop down after typing
a few characters. Note that it is recommended to use mod_perl when
enabling 'ajax_user_autocompletion'.
