Generic Reporting

Bugzilla has a mechanism for generating reports of the current state of the bug database. It has two related parts: a table-based view, and several graphical views.

The table-based view allows you to specify an x, y and z (multiple tables of data) axis to plot, and then restrict the bugs plotted using the standard query form. You can view the resulting data as an HTML or CSV export (e.g.: for importing into a spreadsheet).

There are also bar, line and pie charts, which are defined in a very similar way. These views may be more appropriate for particular data types, and are suitable for saving and then putting into presentations or web pages.

Generic Charting

Bugzilla has a new mechanism for generating charts (graphs over time) of any arbitrary search. This is known as "New Charts." Legacy data from the previous charting mechanism ("Old Charts") is migrated into the "New Charts" when you upgrade. The Old Charts mechanism remains, but is deprecated and will be removed in a future version of Bugzilla.

Individual users can see/create charts as long as they are a member of the group specified in the Param 'chartgroup'. Data can be collected for personal charts every seven days (or a longer period, as set by the user). Charts created by an administrator can be made public (visible to all). Data is collected for administrator charts every day (or a longer period, as set by the admin).

The data is collected by the collectstats.pl script, which an administrator will need to arrange to be run once every day (see the manual). Chart data can be plotted in a number of different ways, and different data sets can be plotted on the same graph for comparison.

Request System

The Request System allows you to flag certain bugs or bug attachments for review. Once flagged, the requested reviewer may approve or reject the flagged bug.

Flags can be made optionally requestable, which means users can ask other users to set them. When a user requests a flag, Bugzilla emails the requestee and adds the request to a browsable queue so both the requester and the requestee can keep track of its status. Once the requestee fulfills the request by setting the flag to either granted or denied, Bugzilla emails the requestee and removes the request from the queue. This feature supports workflow like the mozilla.org code review and milestone approval processes, whereby code is peer reviewed before being committed and patches get approved by product release managers for inclusion in specific product releases.
Product/component specificity
Flags are product/component-specific, and a single flag can be enabled or disabled for multiple product/component combinations via inclusions and exclusions lists. Flags are enabled for all combinations on their inclusions list except those that appear on their exclusions list.

Enterprise Group Support

Administrators can define an arbitrary number of access groups composed of individual users or other groups. The groups can be configured via the web interface to achieve a wide variety of access control policies. See the documentation section on 'Groups And Group Controls' for details.

User Wildcard Matching

Enable the use of wildcards and substrings in bug entry and editing forms. If the user enters an incomplete username, Bugzilla will display a list of users that match the given username.


If the 'insidergroup' parameter is defined, a specific group of users can be designated insiders who can designate comments and attachments as private to other insiders. These comments and attachments will be invisible to other users who are not members of the insiders group even if the bugs to which they apply are visible. Other insiders will see the comments and attachments with a visual tinting indicating that they are private.

Time Tracking

Controls for tracking time spent fixing bugs are included in the bug form for members of the group specified by the 'timetrackinggroup' parameter. Any time comments are added to the bug, members of the time tracking group can add an amount of time they spent, and it's figured into the total and displayed at the top of the bug. Shown in the bug are your original estimate, the amount of time spent so far, the revised estimate of how much time is remaining, and your gain/loss on the original estimate.

Multiple Authentication Methods

Bugzilla's authentication mechanisms are modular, making it very easy to add custom authentication methods to the system as needed. Bugzilla has built-in support for MySQL and LDAP authentication methods, but other methods are easily attainable with minimal custom development.

LDAP logins use Perl's standard Net::LDAP module, which has no external library dependencies.

Improved localization support

Bugzilla administrators can now configure which languages are supported by their installations and automatically serve correct, localized content to users based on the HTTP 'Accept-Language' header sent from users' browsers.

There are currently localized templates available for:

  • Arabic
  • Belarusian
  • Chinese
  • French
  • German
  • Italian
  • Korean
  • Portuguese (Brazil)
  • Spanish (Spain or Mexico)
  • Russian

These localized template packs are third-party contributions, may only be available for specific versions, and may not be supported in the future. (https://www.bugzilla.org/download/#localizations)

Patch Viewer

Viewing and reviewing patches in Bugzilla is often difficult due to lack of context, improper format and the inherent readability issues that raw patches present. Patch Viewer is an enhancement to Bugzilla designed to fix that by offering increased context, linking to sections, and integrating with Bonsai, LXR and CVS.

Comment Reply Links

In Edit Bug, each bug comment now includes a convenient (reply) link that quotes the comment text into the textarea. This feature is only enabled in Javascript-capable browsers, but causes no inconvenience to other user agents.

Full-Text Search

It is now possible to query the Bugzilla database using full-text searching, which spans comments and summaries, and which searches for substrings and stem variations of the search term. Basically, it's like using Google. This search page is now presented to first-time users as the default search, however their choice of seearch page is remembered in a cookie, so clicking the 'Search' link will always return to the most-recently visited search page.

Email Address Munging

The fact that raw email addresses are displayed in Bugzilla makes it trivial for bots that spamharvest to spider through Bugzilla, in particular, through Bugzilla's buglists. This change adds HTML obfuscation of email addresses as they appear in the Bugzilla web pages.

Google-like Bug Search

Bugzilla now includes a very simple, Google-like "Find a Specific Bug" page, in addition to its advanced search page.

Miscellaneous Features

  • The "Assigned To" field on the new bug page is now prefilled with the default component owner.
  • A bug alias column is now available in the buglist page.
  • Lists of bugs containing errors in the sanity check page now have a "view as buglist" link in addition to the individual bug links.
  • Autolinkification Page - It's now possible to apply Bugzilla's comment hyperlinking algorithm to any text you like. This should be useful for status updates and other web pages which give lists of bugs. The bug links created include the subject, status and resolution of the bug as a tooltip.
  • There are more <link> tags on the links toolbar for navigating quickly between different areas.
  • Buglists are now available as comma-separated value files (CSV) and JavaScript (JS) as well as HTML and RDF.
  • Keywords and dependencies can now be entered during initial bug entry
  • A CSS id signature unique to each Bugzilla installation is now added to the <body> tag on Bugzilla pages to allow custom end-user CSS to explicitly affect Bugzilla.
  • Perl's path has been changed to a normal /usr/bin/perl from the original legacy "bonsaitools" path specifier.
  • A new "always-require-login" parameter allows administrators to require a login before being able to view any page, except the front page.
  • A developer may add an attachment, and also reassign a bug to himself as part of that single action.
  • Bugzilla is now able to use the replication facilities provided by the MySQL database to handle updates from the main database to the secondaries.
  • Mail handling is now between 125% to 175% faster.
  • Guided Bug Entry: You can see a sample enter_bug.cgi template at enter_bug.cgi?format=guided that "guides" users through the process of filing a "good" bug. It needs to be modified before use in your organization.
  • There is now a "Give me some help" link on the Advanced Search page that will enable pop-up help for every field on the page.
  • The Bugzilla administrator can now forbid users from marking bugs RESOLVED when there are unresolved dependencies.
