Introduction
Welcome to Bugzilla 3.6! The focus of the 3.6 release is on improving usability and "polishing up" all our features (by adding some pieces that were "missing" or always wanted), although we also have a few great new features for you, as well!
If you're upgrading, make sure to read Notes On Upgrading From a Previous Version. If you are upgrading from a release before 3.4, make sure to read the release notes for all the previous versions in between your version and this one, particularly the Upgrading section of each version's release notes.
We would like to thank Canonical Ltd., ITA Software, the IBM Linux Technology Center, Red Hat, and Novell for funding the development of various features and improvements in this release of Bugzilla.
Updates in this 3.6.x Release
3.6.8
This release fixes two security issues. See the Security Advisory for details.
In addition, the following important fix has been made in this release:
- Previously, WebServices would only work with
JSON::RPC 0.96 or older due to newer versions being incompatible.JSON::RPC 1.x is now supported as well. (Bug 706753)
3.6.7
This release fixes two security issues. See the Security Advisory for details.
This release also fixes a bug where account lockout notifications were not sent to the maintainer of the Bugzilla installation. (Bug 707594)
3.6.6
This release fixes several security issues. See the Security Advisory for details.
3.6.5
Although the 3.6.x branch will only receive security-related fixes from here on out, there were a few bug fixes that made it into the branch before it was locked to security fixes only. Those bug fixes are now being released as 3.6.5.
- During installation, the CPAN module Math::Random::Secure would
sometimes fail to install properly and give an error about
Math::Random::Secure::irand. Now, when using
install-module.pl to install Math::Random::Secure, this
will no longer happen. If you are currently experiencing this bug
and it prevented you from installing 3.6.4, remove Math::Random::Secure
from your lib/ directory, like:
rm -rf lib/Math/Random/Secure*
- Doing "contains all of the words" searches on the Keywords field now works properly again. (Bug 490322)
- It was possible to create a BUGLIST cookie that was longer than 4KB, making the web server refuse all of your requests from then on. (Bug 480044)
- whine.pl will now work on PostgreSQL 8.4 and later. (Bug 616981)
- If you installed Math::Random::Secure in Bugzilla's lib/ directory, mod_perl installations sometimes wouldn't be able to use it. (Bug 621597)
3.6.4
This release fixes several security issues, some of which are highly critical. See the Security Advisory for details.
In addition, the following important fixes/changes have been made in this release:
- Due to one of the security fixes, Bugzilla 3.6.4 now requires a newer version of the CGI.pm Perl module than previous releases of Bugzilla did. When you run checksetup.pl, it will inform you how to upgrade your CGI.pm module.
- When replying to a comment with a link like "attachment 1234 [details]", the "[details]" link will no longer be duplicated in your reply. (Bug 474766)
- Using Quicksearch no longer requires that the List::MoreUtils module be installed. (Bug 611129)
- When using config.cgi?ctype=rdf, information about products now includes allows_unconfirmed. (Bug 610217)
- When using tabular reports, any value whose name started with a period or an underscore wasn't being displayed. (Bug 617684)
3.6.3
This release fixes various important security issues. See the Security Advisory for details.
In addition, the following important fixes/changes have been made in this release:
- Clicking the "Submit only my new comment" button on the mid-air collision page will no longer result in a "Form field longdesclength was not defined" error. (Bug 591218)
- Saving a search with either of the deadline fields set to "Now" would cause that deadline field to be removed from the saved search. (Bug 590144)
- Searching for bugs "with at least X votes" was instead returning bugs with exactly that many votes. (Bug 584414)
- Typing something like "P1-5" in the quicksearch box should have been searching the Priority field, but it was not. (Bug 585028)
- Users who had passwords less than 6 characters long couldn't log in. Such users could only exist before 3.6, so it looked like after upgrading to 3.6, certain users couldn't log in. (Bug 575947)
- Loading config.cgi?ctype=rdf should now be faster, particularly on installations that have many flags. (Bug 553266 and Bug 605693)
- Non-english templates were not being precompiled by checksetup.pl, leading to reduced performance for localized Bugzilla installations. (Bug 605425)
3.6.2
This release fixes various security issues. See the Security Advisory for details.
In addition, the following important fixes/changes have been made in this release:
- Bugzilla installations running on older versions of IIS will no longer experience the "Undef to trick_taint" errors that would sometimes occur. (Bug 521416)
- Email notifications were missing the dates that comments were made. (Bug 578003)
- Putting a phrase in quotes in the Quicksearch box now works properly, again. (Bug 578494 and Bug 553884)
- Quicksearch was usually (incorrectly) being limited to 200 results. (Bug 581622)
- On Windows, install-module.pl can now properly install DateTime and certain other Perl modules that didn't install properly before. (Bug 576105)
- Searching "keywords" for "contains none of the words" or "does not match regular expression" now works properly. (Bug 562014)
- Doing collectstats.pl --regenerate now works on installations using PostgreSQL. (Bug 577058)
- The "Field Values" administrative control panel was sometimes denying admins the ability to delete field values when there was no reason to deny the deletion. (Bug 577054)
- Eliminate the "uninitialized value" warnings that would happen when editing a product's components. (Bug 576911)
- The updating of bugs_fulltext that happens during checksetup.pl for upgrades to 3.6 should now be MUCH faster. (Bug 577754)
- email_in.pl was not allowing the setting of time-tracking fields via inbound emails. (Bug 583622)
3.6.1
This release fixes two security issues. See the Security Advisory for details.
In addition, the following important fixes/changes have been made in this release:
- Using the "Change Columns" page would sometimes result in a plain-text page instead of HTML. (Bug 376044)
- Extensions that have only templates and no code are now working. (Bug 562551)
- install-module.pl has been fixed so that it installs modules properly on both new and old versions of Perl. (Bug 560318 and Bug 560330)
- It is now possible to upgrade from 3.4 to 3.6 when using Oracle. (Bug 561379)
- Editing a field value's name (using the Field Values admin control panel) wasn't working if the value was set as the default for that field. (Bug 561296)
- If you had the noresolveonopenblockers parameter set, bugs couldn't be edited at all if they were marked FIXED and had any open blockers. (The parameter is only supposed to prevent changing bugs to FIXED, not modifying already-FIXED bugs.) (Bug 565314)
- Some minor issues with Perl 5.12 were fixed (mostly warnings that Perl 5.12 was throwing). Bugzilla now supports Perl 5.12.

General Usability Improvements
A scientific usability study was done on Bugzilla by researchers from Carnegie-Mellon University. As a result of this study, several usability issues were prioritized to be fixed, based on specific data from the study.
As a result, you will see many small improvements in Bugzilla's usability, such as using Javascript to validate certain forms before they are submitted, standardizing the words that we use in the user interface, being clearer about what Bugzilla needs from the user, and other changes, all of which are also listed individually in this New Features section.
Work continues on improving usability for the next release of Bugzilla, but the results of the research have already had an impact on this 3.6 release.
New Extensions System
Bugzilla has a brand-new Extensions system. The system is consistent, fast, and fully documented. It makes it possible to easily extend Bugzilla's code and user interface to add new features or change existing features. There's even a script that will create the basic layout of an extension for you, to help you get started. For more information about the new system, see the Extensions documentation.
If you had written any extensions using Bugzilla's previous extensions system, there is a script to help convert old extensions into the new format.
Improved Quicksearch
The "quicksearch" box that appears on the front page of Bugzilla and in the header/footer of every page is now simplified and made more powerful. There is a [?] link next to the box that will take you to the simplified Quicksearch Help, which describes every single feature of the system in a simple layout, including new features such as the ability to use partial field names when searching.
Quicksearch should also be much faster than it was before, particularly on large installations.
Note that in order to implement the new quicksearch, certain old and rarely-used features had to be removed:
- + as a prefix to mean "search additional resolutions", and + as a prefix to mean "search just the summary". You can instead use summary: to explicitly search summaries.
- Searching the Severity field if you type something that matches the first few characters of a severity. You can explicitly search the Severity field if you want to find bugs by severity.
- Searching the Priority field if you typed something that exactly matched the name of a priority. You can explicitly search the Priority field if you want to find bugs by priority.
- Searching the Platform and OS fields if you typed in one of a certain hard-coded list of strings (like "pc", "windows", etc.). You can explicitly search these fields, instead, if you want to find bugs with a specific Platform or OS set.
Simple "Browse" Interface
There is now a "Browse" link in the header of each Bugzilla page that presents a very basic interface that allows users to simply browse through all open bugs in particular components.
SUExec Support
Bugzilla can now be run in Apache's "SUExec" mode, which is what control panel software like cPanel and Plesk use (so Bugzilla should now be much easier to install on shared hosting). SUExec support shows up as an option in the localconfig file during installation.
Experimental mod_perl Support on Windows
There is now experimental support for running Bugzilla under mod_perl on Windows, for a significant performance enhancement (in exchange for using more memory).
Send Attachments by Email
The email_in script now supports attaching multiple attachments to a bug by email, both when filing and when updating a bug.
JSON-RPC Interface
Bugzilla now has support for the JSON-RPC WebServices protocol via jsonrpc.cgi. The JSON-RPC interface is experimental in this release--if you want any fundamental changes in how it works, let us know, for the next release of Bugzilla.
Migration From Other Bug-Trackers
Bugzilla 3.6 comes with a new script, migrate.pl, which allows migration from other bug-tracking systems. Among the various features of the migration system are:
- It is non-destructive--you can migrate into an existing Bugzilla installation without destroying any data in the installation.
- It has a "dry-run" mode so you can test your migration before actually running it.
- It is relatively easy to write new migrators for new systems, if you know Perl. The basic migration framework does most of the work for you, you just have to provide it with the data from your bug-tracker. See the Bugzilla::Migrate documentation and see our current migrator, Bugzilla/Migrate/GNATS.pm for information on how to make your own migrator.
The first migrator that has been implemented is for the GNATS bug-tracking system. We'd love to see migrators for other systems! If you want to contribute a new migrator, see our development process for details on how to get code into Bugzilla.
Thanks to Lambda Research for funding the initial development of this feature.
Other Enhancements and Changes
Enhancements for Users
- Bug Filing: When filing a bug, Bugzilla now visually indicates which fields are mandatory.
- Bug Filing: "Bookmarkable templates" now support the "alias" and "estimated hours" fields.
- Bug Editing: In previous versions of Bugzilla, if you added a private comment to a bug, then none of the changes that you made at that time were sent to users who couldn't see the private comment. Now, for users who can't see private comments, public changes are sent, but the private comment is excluded from their email notification.
- Bug Editing: The controls for groups now appear to the right of the attachment and time-tracking tables, when editing a bug.
- Bug Editing: The "Collapse All Comments" and "Expand All Comments" links now appear to the right of the comment list instead of above it.
- Bug Editing: The See Also field now supports URLs for Google Code Issues and the Debian Bug-Tracking System.
- Bug Editing: There have been significant performance improvements in show_bug.cgi (the script that displays thebug-editing form), particularly for bugs that have lots of comments or attachments.
- Attachments: The "Details" page of an attachment now displays itself as uneditable if you can't edit the fields there.
- Attachments: We now make sure that there is a Description specified for an attachment, using JavaScript, before the form is submitted.
- Attachments: There is now a link back to the bug at the bottom of the "Details" page for an attachment.
- Attachments: When you click on an "attachment 12345" link in a comment, if the attachment is a patch, you will now see the formatted "Diff" view instead of the raw patch.
- Attachments: For text attachments, we now let the browser auto-detect the character encoding, instead of forcing the browser to always assume the attachment is in UTF-8.
- Search: You can now display bug flags as a column in search results.
- Search: When viewing search results, you can see which columns are being sorted on, and which direction the sort is on, as indicated by arrows next to the column headers.
- Search: You can now search the Deadline field using relative dates (like "1d", "2w", etc.).
- Search: The iCalendar format of search results now includes a PRIORITY field.
- Search: It is no longer an error to enter an invalid search order in a search URL--Bugzilla will simply warn you that some of your order options are invalid.
- Search: When there are no search results, some helpful links are displayed, offering actions you might want to take.
- Search: For those who like to make their own buglist.cgi URLs (and for people working on customizations), buglist.cgi now accepts nearly every valid field in Bugzilla as a direct URL parameter, like &field=value.
- Requests: When viewing the "My Requests" page, you can now see the lists as a normal search result by clicking a link at the bottom of each table.
- Requests: When viewing the "My Requests" page, if you are using Classifications, the Product drop-down will be grouped by Classification.
- Inbound Email: When filing a bug by email, if the product that you are filing the bug into has some groups set as Default for you, the bug will now be placed into those groups automatically.
- Inbound Email: The field names that can be used when creating bugs by email now exactly matches the set of valid parameters to the Bug.create WebService function. You can still use most of the old field names that 3.4 and earlier used for inbound emails, though, for backwards-compatibility.
- If there are multiple languages available for your Bugzilla, you can now select what language you want Bugzilla displayed in using links at the top of every page.
- When creating a new account, you will be automatically logged in after setting your password.
- There is no longer a maximum password length for accounts.
- In the Dusk skin, it's now easier to see links.
- In the Whining system, you can now choose to receive emails even if there are no bugs that match your searches.
- The arrows in dependency graphs now point the other way, so that bugs point at their dependencies.
- New Charts: You can now convert an existing Saved Search into a data series for New Charts.
- New Charts: There is now an interface that allows you to delete data series.
- New Charts: When deleting a product, you now have the option to delete the data series that are associated with that product.
Enhancements for Administrators and Developers
- Depending on how your workflow is set up, it is now possible to have both UNCONFIRMED and REOPENED show up as status choices for a closed bug. If you only want one or the other to show up, you should edit your status workflow appropriately (possibly by removing or disabling the REOPENED status).
- You can now "disable" field values so that they don't show up as choices on a bug unless they are already set as the value for that bug. This doesn't work for the per-product field values (component, target_milestone, and version) yet, though.
- Users are now locked out of their accounts for 30 minutes after trying five bad passwords in a row during login. Every time a user is locked out like this, the user in the "maintainer" parameter will get an email.
- The minimum length allowed for a password is now 6 characters.
- The UNCONFIRMED status being enabled in a product is now unrelated to the voting parameters. Instead, there is a checkbox to enable the UNCONFIRMED status in a product.
- Information about duplicates is now stored in the database instead of being stored in the data/ directory. On large installations this could save several hundred megabytes of disk space.
- Installation: When installing Bugzilla, the "maintainer" parameter will be automatically set to the administrator that was created by checksetup.pl.
- Installation: checksetup.pl now prints out certain errors in a special color so that you know that something needs to be done.
- Installation: checksetup.pl is now much faster at upgrading installations, particularly older installations. Also, it's been made faster to run for the case where it's not doing an upgrade.
- Installation: If you install Bugzilla using the tarball, the CGI.pm module from CPAN is now included in the lib/ dir. If you would rather use the CGI.pm from your global Perl installation, you can delete CGI.pm and the CGI directory from the lib/ directory.
- When editing a group, you can now specify that members of a group are allowed to grant others membership in that group itself.
- The ability to compress BMP attachments to PNGs is now an Extension. To enable the feature, remove the file extensions/BmpConvert/disabled and then run checksetup.pl.
- The default list of values for the Priority field are now clear English words instead of P1, P2, etc.
- There is now a system in place so that all field values can be localized. See the value_descs variable in template/en/default/global/field-descs.none.tmpl.
- config.cgi now returns an ETag header and understands the If-None-Match header in HTTP requests.
- The XML format of show_bug.cgi now returns more information: the numeric id of each comment, whether an attachment is a URL, the modification time of an attachment, the numeric id of a flag, and the numeric id of a flag's type.
- Parameters: Parameters that aren't actually required are no longer in the "Required" section of the Parameters page. Instead, some are in the new "General" section, and some are in the new "Advanced" section.
- Parameters: The old ssl parameter has been changed to ssl_redirect, and can only be turned "on" or "off". If "on", then all users will be forcibly redirected to SSL whenever they access Bugzilla. When the parameter is off, no SSL-related redirects will occur (even if the user directly accesses Bugzilla via SSL, they will not be redirected to a non-SSL page).
- Parameters: In the Advanced parameters, there is a new parameter, inbound_proxies. If your Bugzilla is behind a proxy, you should set this parameter to the IP address of that proxy. Then, Bugzilla will "believe" any "X-Forwarded-For" header sent from that proxy, and correctly use the X-Forwarded-For as the end user's IP, instead of believing that all traffic is coming from the proxy.
- Removed Parameter: The loginnetmask parameter has been removed. Since Bugzilla sends secure cookies, it's no longer necessary to always restrict logins to a specific IP or block of addresses.
- Removed Parameter: The quicksearch_comment_cutoff parameter is gone. Quicksearch now always searches comments; however, it uses a much faster algorithm to do it.
- Removed Parameter: The usermatchmode parameter has been removed. User-matching is now always done.
- Removed Parameter: The useentrygroupdefault parameter has been removed. Bugzilla now always behaves as though that parameter were off.
- The t/001compile.t test should now always pass, no matter what configuration of optional modules you do or don't have installed.
- New script: contrib/console.pl, which allows you to have a "command line" into Bugzilla by inputting Perl code or using a few custom commands.
WebService Changes
- The WebService now returns all dates and times in the UTC timezone. Bugzilla.time now acts as though the Bugzilla server were in the UTC timezone, always. If you want to write clients that are compatible across all Bugzilla versions, check the timezone from Bugzilla.timezone or Bugzilla.time, and always input times in that timezone and expect times to be returned in that format.
- You can now log in by passing Bugzilla_login and Bugzilla_password as arguments to any WebService function. See the Bugzilla::WebService documentation for details.
- New Method: Bug.attachments which allows getting information about attachments.
- New Method: Bug.fields, which gets information about all the fields that a bug can have in Bugzilla, include custom fields and legal values for all fields. The Bug.legal_values method is now deprecated.
- In the Bug.add_comment method, the "private" parameter has been renamed to "is_private" (for consistency with other methods). You can still use "private", though, for backwards-compatibility.
- The WebService now has Perl's "taint mode" turned on. This means that it validates all data passed in before sending it to the database. Also, all parameter names are validated, and if you pass in a parameter whose name contains anything other than letters, numbers, or underscores, that parameter will be ignored. Mostly this just affects customizers--Bugzilla's WebService is not functionally affected by these changes.
- In previous versions of Bugzilla, error messages were sent word-wrapped to the client, from the WebService. Error messages are now sent as one unbroken line.
Outstanding Issues
- Bug 423439: Tabs in comments will be converted to four spaces, due to a bug in Perl as of Perl 5.8.8.
- Bug 69621: If you rename or remove a keyword that is in use on bugs, you will need to rebuild the "keyword cache" by running sanitycheck.cgi and choosing the option to rebuild the cache when it asks. Otherwise keywords may not show up properly in search results.
- Bug 89822: When changing multiple bugs at the same time, there is no "mid-air collision" protection.
- Bug 276230: The support for restricting access to
particular Categories of New Charts is not complete. You should treat
the 'chartgroup' Param as the only access mechanism available.
However, charts migrated from Old Charts will be restricted to the groups that are marked MANDATORY for the corresponding Product. There is currently no way to change this restriction, and the groupings will not be updated if the group configuration for the Product changes.
Notes On Upgrading From a Previous Version
When upgrading to 3.6, checksetup.pl will create foreign keys for many columns in the database. Before doing this, it will check the database for consistency. If there are an unresolvable consistency problems, it will tell you what table and column in the database contain the bad values, and which values are bad. If you don't know what else to do, you can always delete the database records which contain the bad values by logging in to your database and running the following command:
DELETE FROM table WHERE column IN
(1, 2, 3, 4)
Just replace "table" and "column" with the name of the table and column that checksetup.pl mentions, and "1, 2, 3, 4" with the invalid values that checksetup.pl prints out.
Remember that you should always back up your database before doing an upgrade.
Code Changes Which May Affect Customizations
- There is no longer a SendBugMail method in the templates, and bugmail is no longer sent by processing a template. Instead, it is sent by using Bugzilla::BugMail::Send.
- Comments are now represented as a Bugzilla::Comment object instead of just being hashes.
- In previous versions of Bugzilla, the template for displaying a bug required a lot of extra variables that are now global template variables instead.
- You can now check if optional modules are installed by using Bugzilla->feature in Perl code or feature_enabled in template code.
- All of the various template header information required to display the bug form is now in one template, template/en/default/bug/show-header.html.tmpl.
- You should now use display_value instead of get_status or get_resolution in templates. display_value should be used anywhere that a <select>-type field has its values displayed.

Updates In This 3.4.x Release
3.4.6
- When doing a search that involves "not equals" or "does not contain the string" or similar "negative" search types, the search description that appears at the top of the resulting bug list will indicate that the search was of that type. (Bug 474738)
- In Internet Explorer, users couldn't easily mark a RESOLVED DUPLICATE bug as REOPENED, due to a JavaScript error. (Bug 546719)
- If you use a "bookmarkable template" to pre-fill forms on the bug-filing page, and you have custom fields that are only supposed to appear (or only supposed to have certain values) based on the values of other fields, those custom fields will now work properly. (Bug 538211)
- If you have a custom field that's only supposed to appear when a bug's resolution is FIXED, it will now behave properly on the bug-editing form when a user sets the bug's status to RESOLVED. (Bug 520993)
- If you are logged-out and using request.cgi, the Requester and Requestee fields no longer respect the usermatching parameter--they always require full usernames. (Bug 533018)
- If you tried to do a search with too many terms (resulting in a URL that was longer than about 7000 characters), Apache would return a 500 error instead of your search results. (Bug 513989)
- Bugzilla would sometimes lose fields from your sort order when you added new fields to your sort order. (Bug 470214)
- The Atom format of search results would sometimes be missing the Reporter or Assignee field for some bugs. (Bug 537834)
3.4.5
This release contains fixes for multiple security issues. See the Security Advisory for details.
In addition, the following important fixes/changes have been made in this release:
- Whining was failing if jobqueue.pl was enabled. (Bug 530270)
- The Assignee field was empty in Whine mails. (Bug 511216)
- Administrators can now successfully create user accounts using editusers.cgi when using the "Env" authentication method. (Bug 483987)
- Bugmail now uses the timezone of the recipient of the email, when displaying the time a comment was made, instead of the timezone of the person who made the change. (Bug 534587)
- "bug 1234" in comments sometimes would not become a link if word-wrapping happened between "bug" and the number. (Bug 514703)
- Running checksetup.pl on Windows will no longer pop up an error box about OCI.dll. (Bug 480968)
3.4.4
This release contains a fix for a security issue. See the Security Advisory for details.
Additionally, this release fixes a few minor bugs.
3.4.3
- Bugzilla installations running under mod_perl were leaking about 512K of RAM per page load. (Bug 517793)
- Attachments with Unicode characters in their names were being downloaded with mangled names. (Bug 328628)
- Creating custom fields with Unicode in their database column name is now no longer allowed, as it would break Bugzilla. If you created such a custom field, you should delete it by first marking it obsolete and then clicking "Delete" in the custom field list, using editfields.cgi. (Bug 525025)
- Clicking "submit only my comment" on the "mid-air collisions" page was leading to a "Suspicious Action" warning. (Bug 514378)
- The XML format of a bug accidentally contained the word-wrapped content of comments instead of the unwrapped content. (Bug 509152)
- You can now do ./install-module.pl --shell to get a CPAN shell using the configuration of install-module.pl, which allows you to do more advanced Perl module installation tasks. (Bug 445875)
3.4.2
This release contains fixes for multiple security issues, one of which is highly critical. See the Security Advisory for details.
In addition, the following important fixes/changes have been made in this release:
- Upgrades from older releases were sometimes failing during UTF-8 conversion with a foreign key error. (Bug 508181)
- Sorting bug lists on certain fields would result in an error. (Bug 510944)
- Bug update emails had two or three blank lines at the top and between the various sections of the email. There is now only one blank line in each of those places, making these emails more compact. (Bug 73330)
- Bug email notifications for new bugs incorrectly had a line saying that the description was "Comment 0". (Bug 510798)
- Running ./collectstats.pl --regenerate is now much faster, on the order of 20x or 100x faster. (Bug 286625)
- For users of RHEL, CentOS, Fedora, etc. jobqueue.pl can now automatically be installed as a daemon by running ./jobqueue.pl install as root. (Bug 475403)
- XML-RPC interface responses had an incorrect Content-Length header and would sometimes be truncated, if they contained certain UTF-8 characters. (Bug 486306)
- Users who didn't have access to the time-tracking fields would get an empty bug update email when the time-tracking fields were changed. (Bug 509035)
- In the New Charts, non-public series now no longer show up as selectable if you cannot access them. (Bug 389396)
3.4.1
This release contains an important security fix. See the Security Advisory for details.

Simple Bug Filing
When entering a new bug, the vast majority of fields are now hidden by default, which enormously simplifies the bug-filing form. You can click "Show Advanced Fields" to show all the fields, if you want them. Bugzilla remembers whether you last used the "Advanced" or "Simple" version of the bug-entry form, and will display the same version to you again next time you file a bug.
New Home Page
Bugzilla's front page has been redesigned to be better at guiding new users into the activities that they most commonly want to do. Further enhancements to the home page are coming in future versions of Bugzilla.
Email Addresses Hidden From Logged-Out Users
To help prevent spam to Bugzilla users, all email addresses stored in Bugzilla are now displayed only if you are logged in. If you are logged out, only the part before the "@" of the email address is displayed. This includes bug lists, viewing bugs, the XML format of a bug, and any other place in the web interface that an email address could appear.
Email addresses are not filtered out of bug comments. The WebService still returns full email addresses, even if you are logged out.
Shorter Search URLs
When submitting a search, all the unused fields are now stripped from the URL, so search URLs are much more meaningful, and much shorter.
Asynchronous Email Sending
The largest performance problem in former versions of Bugzilla was that when updating bugs, email would be sent immediately to every user who needed to be notified, and process_bug.cgi would wait for the emails to be sent before continuing.
Now Bugzilla is capable of queueing emails to be sent while a bug is being updated, and sending them in the background. This requires the administrator to run a daemon that comes with Bugzilla, named jobqueue.pl, and to enable the use_mailer_queue parameter.
Using the background email-sending daemon instead of sending mail directly should result in a very large speed-up for updating bugs, particularly on larger installations.
Dates and Times Displayed In User's Time Zone
Users can now select what time zone they are in and Bugzilla will adjust displayed times to be correct for their time zone. However, times the user inputs are unfortunately still in Bugzilla's time zone.
Custom Fields That Only Appear When Another Field Has a Particular Value
When creating a new custom field (or updating the definition of an existing custom field), you can now say that "this field only appears when field X has value Y". (In the future, you will be able to select multiple values for "Y", so a field will appear when any one of those values is selected.)
This feature only hides fields--it doesn't make their values go away. So bugs will still show up in searches for that field's value, but the field won't appear in the user interface.
This is a good way of making Product-specific fields.
Custom Fields Whose List of Values Change Depending on the Value of Another Field
When creating a drop-down or multiple-selection custom field, you can now specify that another field "controls the values" of this field. Then, when adding values to this field, you can say that a particular value only appears when the other field is set to a particular value.
Here's an example: Let's say that we create a field called "Colors", and we make the Product field "control the values" for Colors. Then we add Blue, Red, Black, and Yellow as legal values for the "Colors" field. Now we can say that "Blue" and "Red" only appear as valid choices in Product A, "Yellow" only appears in Product B, but "Black" always appears.
One thing to note is that this feature only controls what values appear in the user interface. Bugzilla itself will still accept any combination of values as valid, in the backend.
New Custom Field Type: Bug ID
You can now create a custom field that holds a reference to a single valid bug ID. In the future this will be enhanced to allow bugs to refer to each other via this field.
"See Also" Field
We have added a new standard field called "See Also" to Bugzilla. In this field, you can put URLs to multiple bugs in any Bugzilla installation, to indicate that those bugs are related to this one. It also supports adding URLs to bugs in Launchpad.
Right now, the field just validates the URLs and then displays them, but in the future, it will grab information from the other installation about the bug and display it here, and possibly even update the other installation.
If your installation does not need this field, you can hide it by disabling the use_see_also parameter.
Re-order Columns in Search Results
There is a new interface for choosing what columns appear in search results, which allows you to change the order in which columns appear from left to right when viewing the bug list.
Search Descriptions
When displaying search results, Bugzilla will now show a brief description of what you searched for, at the top of the bug list.
Other Enhancements and Changes
Enhancements for Users
- You can now log in from every page, using the login form that appears in the header or footer when you click "Log In".
- When viewing a bug, obsolete attachments are now hidden from the attachment list by default. You can show them by clicking "Show Obsolete" at the bottom of the attachment list.
- In the Email Preferences, you can now choose to get email when a new bug report is filed and you have a particular role on it.
- When resolving a mid-air collision, you can now choose to submit only your comment.
- You can now set the Blocks and Depends On field on the "Change Several Bugs At Once" page.
- If your installation uses the "insidergroup" feature, you can now add private comments on the "Change Several Bugs At Once" page.
- When viewing a search result, you can now hover over any abbreviated field to see its full value.
- When logging out, users are now redirected to the main page of Bugzilla instead of an empty page.
- When editing a bug, text fields (except the comment box) now grow longer when you widen your browser window.
- When viewing a bug, the Depends On and Blocks list will display a bug's alias if it has one, instead of its id. Also, closed bugs will be sorted to the end of the list.
- If you use the time-tracking features of Bugzilla, and you enable the time-tracking related columns in a search result, then you will see a summary of the time-tracking data at the bottom of the search result.
- For users of time-tracking, the summarize_time.cgi page now contains more data.
- When viewing an attachment's details page while you are logged-out, flags are no longer shown as editable.
- Cloning a bug will now retain the "Blocks" and "Depends On" fields from the bug being cloned.
- Bugmail for new bugs will now indicate what security groups the bug has been restricted to.
- You can now use any custom drop-down field as an axis for a tabular or graphical report.
- The X-Bugzilla-Type header in emails sent by Bugzilla is now "new" for bugmail sent for newly-filed bugs, and "changed" for emails having to do with updated bugs.
- Mails sent by the "Whining" system now contain the header X-Bugzilla-Type: whine.
- bugmail now contains a X-Bugzilla-URL header to uniquely identify which Bugzilla installation the email came from.
- If you input an invalid regular expression anywhere in Bugzilla, it will now tell you explicitly instead of failing cryptically.
- The duplicates.xul page (which wasn't used by very many people) is now gone.
Enhancements for Administrators and Developers
- Bugzilla now uses the SHA-256 algorithm (a variant of SHA-2) to encrypt passwords in the database, instead of using Unix's "crypt" function. This allows passwords longer than eight characters to actually be effective. Each user's password will be converted to SHA-256 the first time they log in after you upgrade to Bugzilla 3.4 or later.
- If you are using database replication with Bugzilla, many more scripts now take advantage of the read-only slave (the "shadowdb"). It may be safe to open up show_bug.cgi to search-engine indexing by editing your robots.txt file, now, if your Bugzilla is on fast-enough hardware.
- The database now uses foreign keys to enforce the validity of relationships between tables. Not every single table has all its foreign keys yet, but most do.
- Various parameters have been removed, in an effort to de-clutter the parameter interface and simplify Bugzilla's code. The parameters that were removed were: timezone, supportwatchers, maxpatchsize, commentonclearresolution, commentonreassignbycomponent, showallproducts. They have all been replaced with sensible default behaviors. (For example, user watching is now always enabled.)
- When adding
&debug=1
to the end of a buglist.cgi URL, Bugzilla will now also do an EXPLAIN on the query, to help debug performance issues. - When editing flag types in the administrative interface, you can now see how many flags of each type have been set.
WebService Changes
- Various functions have been added to the WebService: Bug.history, Bug.search, Bug.comments, Bug.update_see_also, User.get, and Bugzilla.time (Bugzilla.timezone is now deprecated).
- For network efficiency, you can now limit which fields are returned from certain WebService functions, like User.get.
- There is now a "permissive" argument for the Bug.get WebService function, which causes it not to throw an error when you ask for bugs you can't see.
- The Bug.get method now returns many more fields.
- The Bug.add_comment method now returns the ID of the comment that was just added.
- The Bug.add_comment method will now throw an error if you try to add a private comment but do not have the correct permissions. (In previous versions, it would just silently ignore the private argument if you didn't have the correct permissions.)
- Many WebService function parameters now take individual values in addition to arrays.
- The WebService now validates input types--it makes sure that dates are in the right format, that ints are actually ints, etc. It will throw an error if you send it invalid data. It also accepts empty ints, doubles, and dateTimes, and translates them to undef.
Outstanding Issues
- Bug 423439: Tabs in comments will be converted to four spaces, due to a bug in Perl as of Perl 5.8.8.
- Bug 69621: If you rename or remove a keyword that is in use on bugs, you will need to rebuild the "keyword cache" by running sanitycheck.cgi and choosing the option to rebuild the cache when it asks. Otherwise keywords may not show up properly in search results.
- Bug 89822: When changing multiple bugs at the same time, there is no "mid-air collision" protection.
- Bug 276230: The support for restricting access to
particular Categories of New Charts is not complete. You should treat
the 'chartgroup' Param as the only access mechanism available.
However, charts migrated from Old Charts will be restricted to the groups that are marked MANDATORY for the corresponding Product. There is currently no way to change this restriction, and the groupings will not be updated if the group configuration for the Product changes. - Bug 370370: mod_perl support is currently not working on Windows machines.
Notes On Upgrading From a Previous Version
When upgrading to 3.4, checksetup.pl will create foreign keys for many columns in the database. Before doing this, it will check the database for consistency. If there are an unresolvable consistency problems, it will tell you what table and column in the database contain the bad values, and which values are bad. If you don't know what else to do, you can always delete the database records which contain the bad values by logging in to your database and running the following command:
DELETE FROM table WHERE column IN
(1, 2, 3, 4)
Just replace "table" and "column" with the name of the table and column that checksetup.pl mentions, and "1, 2, 3, 4" with the invalid values that checksetup.pl prints out.
Remember that you should always back up your database before doing an upgrade.
Code Changes Which May Affect Customizations
- checksetup.pl now re-writes the localconfig
file every time it runs, keeping the current values set (if there
are any), but moving any unexpected variables into a file called
localconfig.old. If you want to continue having custom
varibles in localconfig, you will have to add them to
the
LOCALCONFIG_VARS
constant in Bugzilla::Install::Localconfig. - Bugzilla::Object->update() now returns something different in list context than it does in scalar context.
- Bugzilla::Object->check() now can take object
ids in addition to names. Just pass in
{ id => $some_value }
. - Instead of being defined in buglist.cgi, columns for
search results are now defined in a subroutine called
COLUMNS
in Bugzilla::Search. The data now mostly comes from the fielddefs table in the database. Search.pm now takes a list of column names from fielddefs for its fields argument instead of literal SQL columns. - Bugzilla::Field->legal_values now returns an array of Bugzilla::Field::Choice objects instead of an array of strings. Bugzilla::Field::Choice will be used in more places, in the future.
- We now use Bugzilla::Bug->check() instead of ValidateBugId.
- The groups and bless_groups methods in Bugzilla::User now return an arrayref of Bugzilla::Group objects instead of a hashref with group ids and group names.
- Standard Bugzilla drop-down fields now have their type set to FIELD_TYPE_SINGLE_SELECT in the fielddefs table.
- Bugzilla->usage_mode now defaults to USAGE_MODE_CMDLINE if we are not running inside a web server.
- We no longer delete environment variables like $ENV{PATH} automatically unless we're actually running in taint mode.
- We are now using YUI 2.6.0.
- In the RDF format of config.cgi, the "resource" attribute for flags now contains "flag.cgi" instead of "flags.cgi".

Introduction
Welcome to Bugzilla 3.2! This is our first major feature release since Bugzilla 3.0, and it brings a lot of great improvements and polish to the Bugzilla experience.
If you're upgrading, make sure to read How to Upgrade From An Older Version. If you are upgrading from a release before 3.0, make sure to read the release notes for all the previous versions in between your version and this one, particularly the "Notes For Upgraders" section of each version's release notes.
Updates in this 3.2.x Release
This section describes what's changed in the most recent bug-fix releases of Bugzilla after 3.2. We only list the most important fixes in each release. If you want a detailed list of everything that's changed in each version, you should use our Change Log Page.
3.2.3
- Bugzilla is now compatible with MySQL 5.1.x versions 5.1.31 and greater. (Bug 480001)
- On Windows, Bugzilla sometimes would send mangled emails (that would often fail to send). (Bug 467920)
recode.pl
would sometimes crash when trying to convert databases from older versions of Bugzilla. (Bug 431201)- Running a saved search with Unicode characters in its name would cause Bugzilla to crash. (Bug 477513)
- Bugzilla clients like Mylyn can now update bugs again (the bug XML format now contains a "token" element that can be used when updating a bug). (Bug 476678)
- For installations using the
shadowdb
parameter, Bugzilla was accidentally writing to the "tokens" table in the shadow database (instead of the master database) when using the "Change Several Bugs at Once" page. (Bug 476943)
This release also contains a security fix. See the Security Fixes Section for details.
3.2.2
This release fixes one security issue that is critical for installations running 3.2.1 under mod_perl. See the Security Advisory for details.
3.2.1
- Attachments, charts, and graphs would sometimes be garbled on Windows. (Bug 464992)
- Saving changes to parameters would sometimes fail silently (particularly
on Windows when the web server didn't have the right permissions to
update the
params
file). Bugzilla will now throw an error in this case, telling you what is wrong. (Bug 347707) - If you were using the
usemenuforusers
parameter, and a bug was assigned to (or had a QA Contact of) a disabled user, that field would be reset to the first user in the list when updating a bug. (Bug 465589) - If you were using the
PROJECT
environment variable to have multiple Bugzilla installations using one codebase, project-specific templates were being ignored. (Bug 467324) - Some versions of the SOAP::Lite Perl module had a bug that caused
Bugzilla's XML-RPC service to break.
checksetup.pl
now checks for these bad versions and will reject them. (Bug 468009) - The font sizes in various places were too small, when using the Classic skin. (Bug 469136)
Security Fixes In This 3.2.x Release
3.2.3
This release fixes one security issue related to attachments. See the Security Advisory for details.
3.2.2
This release fixes one security issue that is critical for installations running 3.2.1 under mod_perl. See the Security Advisory for details.
3.2.1
This release contains several security fixes. One fix may break any automated scripts you have that are loading process_bug.cgi directly. We recommend that you read the entire Security Advisory for this release.

New Features and Improvements
- Major UI Improvements
- New Default Skin: Dusk
- Custom Status Workflow
- New Custom Field Types
- Easier Installation
- Experimental Oracle Support
- Improved UTF-8 Support
- Group Icons
- Other Enhancements and Changes
Major UI Improvements
Bugzilla 3.2 has had some UI assistance from the NASA Human-Computer Interaction department and the new Bugzilla User Interface Team.
In particular, you will notice a massively redesigned bug editing form, in addition to our new skin.
New Default Skin: Dusk
Bugzilla 3.2 now ships with a skin called "Dusk" that is a bit more colorful than old default "Classic" skin.
Upgrading installations will still default to the "Classic" skin--administrators can change the default in the Default Preferences control panel. Users can also choose to use the old skin in their Preferences (or using the View :: Page Style menu in Firefox).
The changes that Bugzilla required for Dusk made Bugzilla much easier to skin. See the Addons page for additional skins, or try making your own!
Custom Status Workflow
You can now customize the list of statuses in Bugzilla, and transitions between them.
You can also specify that a comment must be made on certain transitions.
New Custom Field Types
Bugzilla 3.2 has support for three new types of custom fields:
- Large Text: Adds a multi-line textbox to your bugs.
- Multiple Selection Box: Adds a box that allows you to choose multiple items from a list.
- Date/Time: Displays a date and time, along with a JavaScript calendar popup to make picking a date easier.
Easier Installation
Bugzilla now comes with a script called install-module.pl that can automatically download and install all of the required Perl modules for Bugzilla. It stores them in a directory inside your Bugzilla installation, so you can use it even if you don't have administrator-level access to your machine, and without modifying your main Perl install.
checksetup.pl will print out instructions for using install-module.pl, or you can read its documentation.
Experimental Oracle Support
Bugzilla 3.2 contains experimental support for using Oracle as its database. Some features of Bugzilla are known to be broken on Oracle, but hopefully will be working by our next major release.
The Bugzilla Project, as an open-source project, of course does not recommend the use of proprietary database solutions. However, if your organization requires that you use Oracle, this will allow you to use Bugzilla!
The Bugzilla Project thanks Oracle Corp. for their extensive development contributions to Bugzilla which allowed this to happen!
Improved UTF-8 Support
Bugzilla 3.2 now has advanced UTF-8 support in its code, including correct handling for truncating and wrapping multi-byte languages. Major issues with multi-byte or unusual languages are now resolved, and Bugzilla should now be usable by users in every country with little (or at least much less) customization.
Group Icons
Administrators can now specify that users who are in certain groups should have an icon appear next to their name whenever they comment. This is particularly useful for distinguishing developers from bug reporters.
Other Enhancements and Changes
These are either minor enhancements, or enhancements that have very short descriptions. Some of these are very useful, though!
Enhancements For Users
- Bugs: You can now reassign a bug at the same time as you are changing its status.
- Bugs: When entering a bug, you will now see the description of a component when you select it.
- Bugs: The bug view now contains some Microformats, most notably for users' names and email addresses.
- Bugs: You can now remove a QA Contact from a bug simply by clearing the QA Contact field.
- Bugs: There is now a user preference that will allow you to exclude the quoted text when replying to comments.
- Bugs: You can now expand or collapse individual comments in the bug view.
- Attachments: There is now "mid-air collision" protection when editing attachments.
- Attachments: Patches in the Diff Viewer now show line numbers (Example).
- Attachments: After creating or updating an attachment, you will be immediately shown the bug that the attachment is on.
- Search: You can now reverse the sort of a bug list by clicking on a column header again.
- Search: Atom feeds of bug lists now contain more fields.
- Search: QuickSearch now supports searching flags and groups. It also now includes the OS field in the list of fields it searches by default.
- Search: "Help" text can now appear on query.cgi for Internet Explorer and other non-Firefox browsers. (It always could appear for Firefox.)
- Bugzilla now ships with an icon that will show up next to the URL in most browsers. If you want to replace it, it's in images/favicon.ico.
- You can now set the Deadline when using "Change Several Bugs At Once"
- Saved Searches now save their column list, so if you customize the list of columns and save your search, it will always contain those columns.
- Saved Searches: When you share a search, you can now see how many users have subscribed to it, on userprefs.cgi.
- Saved Searches: You can now see what group a shared search was shared to, on the list of available shared searches in userprefs.cgi.
- Flags: If your installation uses drop-down user lists, the flag requestee box will now contain only users who are actually allowed to take requests.
- Flags: If somebody makes a request to you, and you change the requestee to somebody else, the requester is no longer set to you. In other words, you can "redirect" requests and maintain the original requester.
- Flags: Emails about flags now will thread properly in email clients to be a part of a bug's thread.
- When using email_in.pl, you can now add users to the CC list by just using @cc as the field name.
- Many pages (particularly administrative pages) now contain links to the relevant section of the Bugzilla Guide, so you can read the documentation for that page.
- Dependency Graphs should render more quickly, as they now (by default) only include the same bugs that you'd see in the dependency tree.
Enhancements For Administrators
- Admin UI: Instead of having the Administration Control Panel links in the footer, there is now just one link called "Administration" that takes you to a page that links to all the administrative controls for Bugzilla.
- Admin UI: Administrative pages no longer display confirmation pages, instead they redirect you to some useful page and display a message about what changed.
- Admin UI: The interface for editing group inheritance in editgroups.cgi is much clearer now.
- Admin UI: When editing a user, you can now see all the components where that user is the Default Assignee or Default QA Contact.
- Email: For installations that use SMTP to send mail (as opposed to Sendmail), Bugzilla now supports SMTP Authentication, so that it can log in to your mail server before sending messages.
- Email: Using the "Test" mail delivery method now creates a valid mbox file to make testing easier.
- Authentication: Bugzilla now correctly handles LDAP records which contain multiple email addresses. (The first email address in the list that is a valid Bugzilla account will be used, or if this is a new user, the first email address in the list will be used.)
- Authentication: Bugzilla can now take a list of LDAP servers to try in order until it gets a successful connection.
- Authentication: Bugzilla now supports RADIUS authentication.
- Security: The login cookie is now created as "HTTPOnly" so that it can't be read by possibly malicious scripts. Also, if SSL is enabled on your installation, the login cookie is now only sent over SSL connections.
- Security: The
ssl
parameter now protects every page a logged-in user accesses, when set to "authenticated sessions." Also, SSL is now enforced appropriately in the WebServices interface when the parameter is set. - Database: Bugzilla now uses transactions in the database instead of table locks. This should generally improve performance with many concurrent users. It also means if there is an unexpected error in the middle of a page, all database changes made during that page will be rolled back.
- Database: You no longer have to set
max_packet_size
in MySQL to add large attachments. However, you may need to set it manually if you restore a mysqldump into your database. - New WebService functions: Bug.add_comment and Bugzilla.extensions.
- You can now delete custom fields, but only if they have never been set on any bug.
- There is now a --reset-password argument to checksetup.pl that allows you to reset a user's password from the command line.
- There is now a script called sanitycheck.pl that you can run from the command line. It works just like sanitycheck.cgi. By default, it only outputs anything if there's an error, so it's ideal for administrators who want to run it nightly in a cron job.
- The strict_isolation parameter now prevents you from setting users who cannot see a bug as a CC, Assignee, or QA Contact. Previously it only prevented you from adding users who could not edit the bug.
- Extensions can now add their own headers to the HTML <head> for things like custom CSS and so on.
- sanitycheck.cgi has been templatized, meaning that the entire Bugzilla UI is now contained in templates.
- When setting the sslbase parameter, you can now specify a port number in the URL.
- When importing bugs using importxml.pl, attachments will have their actual creator set as their creator, instead of the person who exported the bug from the other system.
- The voting system is off by default in new installs. This is to prepare for the fact that it will be moved into an extension at some point in the future.
- The
shutdownhtml
parameter now works even when Bugzilla's database server is down.
Enhancements for Localizers (or Localized Installations)
- The documentation can now be localized--in other words, you can have documentation installed for multiple languages at once and Bugzilla will link to the correct language in its internal documentation links.
- Bugzilla no longer uses the languages parameter. Instead it reads the template/ directory to see which languages are available.
- Some of the messages printed by checksetup.pl can now be localized. See template/en/default/setup/strings.txt.pl.
Outstanding Issues
- Bug 423439: Tabs in comments will be converted to four spaces, due to a bug in Perl as of Perl 5.8.8.
- Bug 69621: If you rename or remove a keyword that is in use on bugs, you will need to rebuild the "keyword cache" by running sanitycheck.cgi and choosing the option to rebuild the cache when it asks. Otherwise keywords may not show up properly in search results.
- Bug 89822: When changing multiple bugs at the same time, there is no "mid-air collision" protection.
- Bug 276230: The support for restricting access to
particular Categories of New Charts is not complete. You should treat
the 'chartgroup' Param as the only access mechanism available.
However, charts migrated from Old Charts will be restricted to the groups that are marked MANDATORY for the corresponding Product. There is currently no way to change this restriction, and the groupings will not be updated if the group configuration for the Product changes. - Bug 370370: mod_perl support is currently not working on Windows machines.
How to Upgrade From An Older Version
Notes For Upgraders
- If you upgrade by CVS, the extensions and skins/contrib directories are now in CVS instead of being created by checksetup.pl If you do a cvs update from 3.0, you will be told that your directories are "in the way" and you should delete (or move) them and then do cvs update again. Also, the docs directory has been restructured and after you cvs update you can delete the docs/html, docs/pdf, docs/txt, and docs/xml directories.
- If you are using MySQL, you should know that Bugzilla now uses InnoDB for all tables. checksetup.pl will convert your tables automatically, but if you have InnoDB disabled, the upgrade will not be able to complete (and checksetup.pl will tell you so).
- You should also read the Bugzilla 3.0 Notes For Upgraders section of the previous release notes if you are upgrading from a version before 3.0.
Steps For Upgrading
Once you have read the notes above, see the Upgrading documentation for instructions on how to upgrade.
Code Changes Which May Affect Customizations
More Hooks!
There are more code hooks in 3.2 than there were in 3.0. See the documentation of Bugzilla::Hook for more details.
Search.pm Rearchitecture
Bugzilla/Search.pm has been heavily modified, to be much easier to read and use. It contains mostly the same code as it did in 3.0, but it has been moved around and reorganized significantly.
lib Directory
As part of implementing install-module.pl, Bugzilla was given a local lib directory which it searches for modules, in addition to the standard system path.
This means that all Bugzilla scripts now start with
use lib qw(. lib);
as one of the first lines.
Other Changes
- You should now be using
get_status('NEW')
instead ofstatus_descs.NEW
in templates. - The
[%# version = 1.0 %]
comment at the top of every template file has been removed.

Introduction
Welcome to Bugzilla 3.0! It's been over eight years since we released Bugzilla 2.0, and everything has changed since then. Even just since our previous release, Bugzilla 2.22, we've added a lot of new features. So enjoy the release, we're happy to bring it to you.
If you're upgrading, make sure to read How to Upgrade From An Older Version. If you are upgrading from a release before 2.22, make sure to read the release notes for all the previous versions in between your version and this one.
Updates in this 3.0.x Release
This section describes what's changed in the most recent bug-fix releases of Bugzilla after 3.0. We only list the most important fixes in each release. If you want a detailed list of everything that's changed in each version, you should use our Change Log Page.
3.0.6
- Before 3.0.6, unexpected fatal WebService errors would result in
a
faultCode
that was a string instead of a number. (Bug 446327) - If you created a product or component with the same name as one you previously deleted, it would fail with an error about the series table. (Bug 247936)
See also the Security Advisory section for information about a security issue fixed in this release.
3.0.5
- If you don't have permission to set a flag, it will now appear unchangeable in the UI. (Bug 433851)
- If you were running mod_perl, Bugzilla was not correctly closing its connections to the database since 3.0.3, and so sometimes the DB would run out of connections. (Bug 441592)
- The installation script is now clear about exactly which
Email::
modules are required in Perl, thus avoiding the problem where emails show up with a body like SCALAR(0xBF126795). (Bug 441541) - email_in.pl is no longer case-sensitive for values of @product. (Bug 365697)
See also the Security Advisory section for information about security issues fixed in this release.
3.0.4
- Bugzilla administrators were not being correctly notified about new releases. (Bug 414726)
- There could be extra whitespace in email subject lines. (Bug 411544)
- The priority, severity, OS, and platform fields were always required by the Bug.create WebService function, even if they had defaults specified. (Bug 384009)
- Better threading of bugmail in some email clients. (Bug 376453)
- There were many fixes to the Inbound Email Interface (email_in.pl). (Bug 92274, Bug 377025, Bug 412943, Bug 413672, and Bug 431721)
- checksetup.pl now handles UTF-8 conversion more reliably during upgrades. (Bug 374951)
- Comments written in CJK languages are now correctly word-wrapped. (Bug 388723)
- All emails will now be sent in the correct language, when the user has chosen a language for emails. (Bug 405946)
- On Windows, temporary files created when uploading attachments are now correctly deleted when the upload is complete. (Bug 414002)
- checksetup.pl now prints correct installation instructions for Windows users using Perl 5.10. (Bug 414430)
See also the Security Advisory section for information about security issues fixed in this release.
3.0.3
- mod_perl no longer compiles Bugzilla's code for each Apache process individually. It now compiles code only once and shares it among each Apache process. This greatly improves performance and highly decreases the memory footprint. (Bug 398241)
- You can now search for '---' (without quotes) in versions and milestones. (Bug 362436)
- Bugzilla should no longer break lines unnecessarily in email subjects. This was causing trouble with some email clients. (Bug 374424)
- If you had selected "I'm added to or removed from this capacity" option for the "CC" role in your email preferences, you wouldn't get mail when more than one person was added to the CC list at once. (Bug 394796)
- Deleting a user account no longer deletes whines from another user who has the deleted account as addressee. The schedule is simply removed, but the whine itself is left intact. (Bug 395924)
- contrib/merge-users.pl now correctly merges all required fields when merging two user accounts. (Bug 400160)
- Bugzilla no longer requires Apache::DBI to run under mod_perl. It caused troubles such as lost connections with the DB and didn't give any important performance gain. (Bug 408766)
3.0.2
- Bugzilla should now work on Perl 5.9.5 (and thus the upcoming Perl 5.10.0). (Bug 390442)
See also the Security Advisory section for information about an important security issue fixed in this release.
3.0.1
- For users of Firefox 2, the
show_bug.cgi
user interface should no longer "collapse" after you modify a bug. (Bug 370739) - If you can bless a group, and you share a saved search with that group, it will no longer automatically appear in all of that group's footers unless you specifically request that it automatically appear in their footers. (Bug 365890)
- There is now a parameter to allow users to perform searches without
any search terms. (In other words, to search for just a Product
and Status on the Simple Search page.) The parameter is called
specific_search_allow_empty_words
. (Bug 385910) - If you attach a file that has a MIME-type of
text/x-patch
ortext/x-diff
, it will automatically be treated as a patch by Bugzilla. (Bug 365756) - Dependency Graphs now work correctly on all mod_perl installations. There should now be no remaining signficant problems with running Bugzilla under mod_perl. (Bug 370398)
- If moving a bug between products would remove groups from the bug, you are now warned. (Bug 303183)
- On IIS, whenever Bugzilla threw a warning, it would
actually appear on the web page. Now warnings are suppressed,
unless you have a file in the
data
directory callederrorlog
, in which case warnings will be printed there. (Bug 390148) - If you used email_in.pl to edit a bug that was protected by groups, all of the groups would be cleared. (Bug 385453)
- PostgreSQL users: New Charts were failing to collect data over time. They will now start collecting data correctly. (Bug 257351)
- Some flag mails didn't specify who the requestee was. (Bug 379787)
- Instead of throwing real errors, collectstats.pl would
just say that it couldn't find
ThrowUserError
. (Bug 380709) - Logging into Bugzilla from the home page works again with IIS5. (Bug 364008)
- If you were using SMTP for sending email, sometimes emails would
be missing the
Date
header. (Bug 304999). - In the XML-RPC WebService,
Bug.legal_values
now correctly returns values for custom fields if you request values for custom fields. (Bug 381737) - The "Bug-Writing Guidelines" page has been shortened and re-written. (Bug 378590)
- If your
urlbase
parameter included a port number, likewww.domain.com:8080
, SMTP might have failed. (Bug 384501) - For SMTP users, there is a new parameter,
smtp_debug
. Turning on this parameter will log the full information about every SMTP session to your web server's error log, to help with debugging issues with SMTP. (Bug 384497) - If you are a "global watcher" (you get all mails from every bug), you can now see that in your Email Preferences. (Bug 365302)
- The Status and Resolution of bugs are now correctly localized in CSV search results. (Bug 389517)
- The "Subject" line of an email was being mangled if it contained non-Latin characters. (Bug 387860)
- Editing the "languages" parameter using editparams.cgi would sometimes fail, causing Bugzilla to throw an error. (Bug 335354)

Custom Fields
Bugzilla now includes very basic support for custom fields.
Users in the admin group can add plain-text or drop-down custom fields. You can edit the values available for drop-down fields using the "Field Values" control panel.
Don't add too many custom fields! It can make Bugzilla very difficult to use. Try your best to get along with the default fields, and then if you find that you can't live without custom fields after a few weeks of using Bugzilla, only then should you start your custom fields.
mod_perl Support
Bugzilla 3.0 supports mod_perl, which allows for extremely enhanced page-load performance. mod_perl trades memory usage for performance, allowing near-instantaneous page loads, but using much more memory.
If you want to enable mod_perl for your Bugzilla, we recommend a minimum of 1.5GB of RAM, and for a site with heavy traffic, 4GB to 8GB.
If performance isn't that critical on your installation, you don't have the memory, or you are running some other web server than Apache, Bugzilla still runs perfectly as a normal CGI application, as well.
Shared Saved Searches
Users can now choose to "share" their saved searches with a certain group. That group will then be able to "subscribe" to those searches, and have them appear in their footer.
If the sharer can "bless" the group he's sharing to, (that is, if he can add users to that group), it's considered that he's a manager of that group, and his queries show up automatically in that group's footer (although they can unsubscribe from any particular search, if they want.)
In order to allow a user to share their queries, they also
have to be a member of the group specified in the
querysharegroup
parameter.
Users can control their shared and subscribed queries from the "Preferences" screen.
Attachments and Flags on New Bugs
You can now add an attachment while you are filing a new bug.
You can also set flags on the bug and on attachments, while filing a new bug.
Custom Resolutions
You can now customize the list of resolutions available in Bugzilla, including renaming the default resolutions.
The resolutions FIXED
, DUPLICATE
and MOVED
have a special meaning to Bugzilla,
though, and cannot be renamed or deleted.
Per-Product Permissions
You can now grant users editbugs and canconfirm for only certain products. You can also grant users editcomponents on a product, which means they will be able to edit that product including adding/removing components and other product-specific controls.
User Interface Improvements
There has been some work on the user interface for Bugzilla 3.0, including:
- There is now navigation and a search box a the top of each page, in addition to the bar at the bottom of the page.
- A re-designed "Format for Printing" page for bugs.
- The layout of show_bug.cgi (the bug editing page) has been changed, and the attachment table has been redesigned.
XML-RPC Interface
Bugzilla now has a Web Services interface using the XML-RPC protocol. It can be accessed by external applications by going to the xmlrpc.cgi on your installation.
Documentation can be found in the Bugzilla API Docs, in the various Bugzilla::WebService modules.
Skins
Bugzilla can have multiple "skins" installed, and users can pick between them. To write a skin, you just have to write several CSS files. See the Custom Skins Documentation for more details.
We currently don't have any alternate skins shipping with Bugzilla. If you write an alternate skin, please let us know!
Unchangeable Fields Appear Unchangeable
As long as you are logged in, when viewing a bug, if you cannot change a field, it will not look like you can change it. That is, the value will just appear as plain text.
All Emails in Templates
All outbound emails are now controlled by the templating system.
What used to be the passwordmail
, whinemail
,
newchangedmail
and voteremovedmail
parameters are now all templates in the template/ directory.
This means that it's now much easier to customize your outbound emails, and it's also possible for localizers to have more localized emails as part of their language packs, if they want.
We also added a mailfrom
parameter to let you set
who shows up in the From
field on all emails that
Bugzilla sends.
No More Double-Filed Bugs
Users of Bugzilla will sometimes accidentally submit a bug twice, either by going back in their web browser, or just by refreshing a page. In the past, this could file the same bug twice (or even three times) in a row, irritating developers and confusing users.
Now, if you try to submit a bug twice from the same screen (by going back or by refreshing the page), Bugzilla will warn you about what you're doing, before it actually submits the duplicate bug.
Default CC List for Components
You can specify a list of users who will always be added to the CC list of new bugs in a component.
File/Modify Bugs By Email
You can now file or modify bugs via email. Previous versions of Bugzilla included this feature only as an unsupported add-on, but it is now an official interface to Bugzilla.
For more details see the documentation for email_in.pl.
Users Who Get All Bug Notifications
There is now a parameter called globalwatchers. This is a comma-separated list of Bugzilla users who will get all bug notifications generated by Bugzilla.
Group controls still apply, though, so users who can't see a bug still won't get notifications about that bug.
Improved UTF-8 Support
Bugzilla users running MySQL should now have excellent UTF-8 support if they turn on the utf8 parameter. (New installs have this parameter on by default.) Bugzilla now correctly supports searching and sorting in non-English languages, including multi-bytes languages such as Chinese.
Automatic Update Notification
If you belong to the admin group, you will be notified when you log in if there is a new release of Bugzilla available to download.
You can control these notifications by changing the upgrade_notification parameter.
If your Bugzilla installation is on a machine that needs to go through a proxy to access the web, you may also have to set the proxy_url parameter.
Welcome Page for New Installs
When you log in for the first time on a brand-new Bugzilla installation, you will be presented with a page that describes where you should go from here, and what parameters you should set.
QuickSearch Plugin for IE7 and Firefox 2
Firefox 2 users and Internet Explorer 7 users will be presented with the option to add Bugzilla to their search bar. This uses the QuickSearch syntax.
Other Enhancements and Changes
These are either minor enhancements, or enhancements that have very short descriptions. Some of these are very useful, though!
Enhancements That Affect Bugzilla Users
- In comments, quoted text (lines that start with >) will be a different color from normal text.
- There is now a user preference that will add you to the CC list of any bug you modify. Note that it's on by default.
- Bugs can now be filed with an initial state of ASSIGNED, if you are in the editbugs group.
- By default, comment fields will zoom large when you are typing in them, and become small when you move out of them. You can disable this in your user preferences.
- You can hide obsolete attachments on a bug by clicking "Hide Obsolete" at the bottom of the attachment table.
- If a bug has flags set, and you move it to a different product that has flags with the same name, the flags will be preserved.
- You now can't request a flag to be set by somebody who can't set it (Bugzilla will throw an error if you try).
- Many new headers have been added to outbound Bugzilla
bug emails:
X-Bugzilla-Status
,X-Bugzilla-Priority
,X-Bugzilla-Assigned-To
,X-Bugzilla-Target-Milestone
, andX-Bugzilla-Changed-Fields
,X-Bugzilla-Who
. You can look at an email to get an idea of what they contain. - In addition to the old
X-Bugzilla-Reason
email header which tells you why you got an email, if you got an email because you were watching somebody, there is now anX-Bugzilla-Watch-Reason
header that tells you who you were watching and what role they had. - If you hover your mouse over a full URL (like
http://bugs.mycompany.com/show_bug.cgi?id=1212
) that links to a bug, you will see the title of the bug. Of course, this only works for bugs in your Bugzilla installation. - If your installation has user watching enabled, you will now see the users that you can remove from your watch-list as a multi-select box, much like the current CC list. (Previously it was just a text box.)
- When a user creates their own account in Bugzilla, the account is now not actually created until they verify their email address by clicking on a link that is emailed to them.
- You can change a bug's resolution without reopening it.
- When you view the dependency tree on a bug, resolved bugs will be hidden by default. (In previous versions, resolved bugs were shown by default.)
- When viewing bug activity, fields that hold bug numbers (such as "Blocks") will have the bug numbers displayed as links to those bugs.
- When viewing the "Keywords" field in a bug list, it will be sorted alphabetically, so you can sanely sort a list on that field.
- In most places, the Version field is now sorted using a version-sort (so 1.10 is greater than 1.2) instead of an alphabetical sort.
- Options for flags will only appear if you can set them. So, for example, if you can't grant + on a flag, that option won't appear for you.
- You can limit the product-related output of config.cgi by specifying a product= URL argument, containing the name of a product. You can specify the argument more than once for multiple products.
- You can now search the boolean charts on whether or not a comment is private.
Enhancements For Administrators
- Administrators can now delete attachments, making them disappear entirely from Bugzilla.
- sanitycheck.cgi can now only be accessed by users in the editcomponents group.
- The "Field Values" control panel can now only be accessed by users in the admin group. (Previously it was accessible to anybody in the editcomponents group.)
- There is a new parameter announcehtml, that will allow you to enter some HTML that will be displayed at the top of every page, as an announcement.
- The loginnetmask parameter now defaults to 0 for new installations, meaning that as long as somebody has the right login cookie, they can log in from any IP address. This makes life a lot easier for dial-up users or other users whose IP changes a lot. This could be done because the login cookie is now very random, and thus secure.
- Classifications now have sortkeys, so they can be sorted in an order that isn't alphabetical.
- Authentication now supports LDAP over SSL (LDAPS) or TLS (using the STARTLS command) in addition to plain LDAP.
- LDAP users can have their LDAP username be their email address, instead of having the LDAP mail attribute be their email address. You may wish to set the emailsuffix parameter if you do this.
- Administrators can now see what has changed in a user account, when using the "Users" control panel.
REMIND
andLATER
are no longer part of the default list of resolutions. Upgrading installations will not be affected--they will still have these resolutions.- editbugs is now the default for the timetrackinggroup parameter, meaning that time-tracking will be on by default in a new installation.
Outstanding Issues
- Bug 69621: If you rename or remove a keyword that is in use on bugs, you will need to rebuild the "keyword cache" by running sanitycheck.cgi and choosing the option to rebuild the cache when it asks. Otherwise keywords may not show up properly in search results.
- Bug 99215: Flags are not protected by "mid-air collision" detection. Nor are any attachment changes.
- Bug 89822: When changing multiple bugs at the same time, there is no "mid-air collision" protection.
- Bug 276230: The support for restricting access to
particular Categories of New Charts is not complete. You should treat
the 'chartgroup' Param as the only access mechanism available.
However, charts migrated from Old Charts will be restricted to the groups that are marked MANDATORY for the corresponding Product. There is currently no way to change this restriction, and the groupings will not be updated if the group configuration for the Product changes. - Bug 370370: mod_perl support is currently not working on Windows machines.
- Bug 361149: If you are using Perl 5.8.0, you may get a lot of warnings in your Apache error_log about "deprecated pseudo-hashes." These are harmless--they are a bug in Perl 5.8.0. Perl 5.8.1 and later do not have this problem.
- Bugzilla 3.0rc1 allowed custom field column names in the database to be mixed-case. Bugzilla 3.0 only allows lowercase column names. It will fix any column names that you have made mixed-case, but if you have custom fields that previously were mixed-case in any Saved Search, you will have to re-create that Saved Search yourself.

fixed in this release: one minor information leak, one hole only
exploitable by an admin or using email_in.pl
, and one in an
uncommonly-used template. For details, see the
Security Advisory.
How to Upgrade From An Older Version
Notes For Upgraders
- If you upgrade by CVS, there are several .cvsignore files that are now in CVS instead of being locally created by checksetup.pl. This means that you will have to delete those files when CVS tells you there's a conflict, and then run cvs update again.
- In this version of Bugzilla, the Summary field is now limited to 255 characters. When you upgrade, any Summary longer than that will be truncated, and the old summary will be preserved in a comment.
- If you have the utf8 parameter turned on, at some point you will have to convert your database. checksetup.pl will tell you when this is, and it will give you certain instructions at that time, that you have to follow before you can complete the upgrade. Don't do the conversion yourself manually--follow the instructions of checksetup.pl.
- If you ever ran 2.23.3, 2.23.4, or 3.0rc1, you will have to run ./collectstats.pl --regenerate at the command line, because the data for your Old Charts is corrupted. This can take several days, so you may only want to run it if you use Old Charts.
- You should also read the Outstanding Issues sections of older release notes if you are upgrading from a version lower than 2.22.
Steps For Upgrading
Once you have read the notes above, see the Upgrading documentation for instructions on how to upgrade.
Code Changes Which May Affect Customizations

Packagers: Location Variables Have Moved
In previous versions of Bugzilla, Bugzilla::Config held all the paths for different things, such as the path to localconfig and the path to the data/ directory.
Now, all of this data is stored in a subroutine, Bugzilla::Constants::bz_locations.
Also, note that for mod_perl, bz_locations must return absolute (not relative) paths. There is already code in that subroutine to help you with this.
Hooks!
Bugzilla now supports a code hook mechanism. See the documentation for Bugzilla::Hook for more details.
This gives Bugzilla very advanced plugin support. You can hook templates, hook code, add new parameters, and use the XML-RPC interface. So we'd like to see some Bugzilla plugins written! Let us know on the developers@bugzilla.org mailing list if you write a plugin.
If you need more hooks, please File a bug!
API Documentation
Bugzilla now ships with all of its perldoc built as HTML. Go ahead and read the API Documentation for all of the Bugzilla modules now! Even scripts like checksetup.pl have HTML documentation.
Elimination of globals.pl
The old file globals.pl has been eliminated. Its code is now in various modules. Each function went to the module that was appropriate for it.
Usually we filed a bug in bugzilla.mozilla.org for each function we moved. You can search there for the old name of the function, and that should get you the information about what it's called now and where it lives.
Cleaned Up Variable Scoping Issues
In normal perl, you can have code like this:
my $var = 0; sub y { $var++ }
However, under mod_perl that doesn't work. So variables are no longer "shared" with subroutines--instead all variables that a subroutine needs must be declared inside the subroutine itself.
No More SendSQL
The old SendSQL function and all of its companions are gone. Instead, we now use DBI for all database interaction.
For more information about how to use DBI with Bugzilla, see the Developer's Guide Section About DBI
Auth Re-write
The Bugzilla::Auth family of modules have been completely re-written. For details on how the new structure of authentication, read the Bugzilla::Auth API docs.
It should be very easy to write new authentication plugins, now.
Bugzilla::Object
There is a new base class for most of our objects, Bugzilla::Object. It makes it really easy to create new objects based on things that are in the database.
Bugzilla->request-cache
Bugzilla.pm used to cache things like the database
connection in package-global variables (like $_dbh).
That doesn't work in mod_perl, so instead now there's a hash
that can be accessed through Bugzilla->request_cache
to store things for the rest of the current page request.
You shouldn't access Bugzilla->request_cache
directly,
but you should use it inside of Bugzilla.pm if you modify
that. The only time you should be accessing it directly is if you need
to reset one of the caches. Hash keys are always named after the function
that they cache, so to reset the template object, you'd do:
delete Bugzilla->request_cache->{template};
.
Other Changes
checksetup.pl
has been completely re-written, and most of its code moved into modules in the Bugzilla::Install namespace. See the checksetup documentation and Bugzilla bug 277502 for details.- Instead of UserInGroup(), all of Bugzilla now uses Bugzilla->user->in_group
- mod_perl doesn't like dependency loops in modules, so we now have a test for that detects dependency loops in modules when you run runtests.pl.
- globals.pl used to modify the environment variables, like PATH. That now happens in Bugzilla.pm.
- Templates can now link to the documentation more easily. See the global/code-error.html.tmpl and global/user-error.html.tmpl templates for examples. (Search for "docslinks.")
- Parameters are accessed through Bugzilla->params instead of using the Param() function, now.
- The variables from the localconfig file are accessed
through the
Bugzilla->localconfig
hash instead of through Bugzilla::Config. - Bugzilla::BugMail::MessageToMTA() has moved into its own module, along with other mail-handling code, called Bugzilla::Mailer
- The CheckCanChangeField() subroutine in process_bug.cgi has been moved to Bugzilla::Bug, and is now a method of a bug object.
- The code that used to be in the global/banner.html.tmpl template is now in global/header.html.tmpl. The banner still exists, but the file is empty.
