Bugzilla 4.0 Release Notes

Introduction

This is Bugzilla 4.0! Since 3.6 (our previous major release) we've come a long way, and we've come even further compared to 3.0 in 2007! Since Bugzilla 3.0, almost every major user interface in Bugzilla has been redesigned, the WebServices have evolved enormously, there's a great new Extensions system, and there are hundreds of other new features. With the major redesigns that come particularly in this release compared to 3.6, we felt that it was time to call this release 4.0.

It's not just major WebService and UI enhancements that are new in Bugzilla 4.0—there are many other exciting new features, including automatic duplicate detection, enhanced custom field functionality, autocomplete for users, search improvements, and much more. Overall, 4.0 is far and away the best version of Bugzilla we've ever released.

If you're upgrading, make sure to read Notes On Upgrading From a Previous Version. If you are upgrading from a release before 3.6, 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 ITA Software, the IBM Linux Technology Center, and Red Hat for funding the development of certain features and improvements in this release of Bugzilla.

Optional Apache Modules

If you are using Apache as your webserver, Bugzilla can now take advantage of some Apache features if you have the below Apache modules installed and enabled. Currently, certain Bugzilla features are enabled only if you have all of the following modules installed and enabled:

On most systems (but not on Windows), checksetup.pl is able to tell whether or not you have these modules installed, and it will tell you.

New Features and Improvements

Automatic Duplicate Detection When Filing Bugs

When filing a bug, as soon as you start typing in the summary field, Bugzilla will suggest possible duplicates of the bug you are filing.

In order for this feature to work, all pre-requisites for JSON-RPC support must be installed on your Bugzilla. It will be much faster on installations that run under mod_perl than it will be on other installations.

New Advanced Search UI

Thanks to the UI work of Guy Pyrzak, the Advanced Search UI has been completely redesigned. It is now much simpler, and far more approachable for new users, while still retaining all of the features that power users are used to.

New Attachment Details UI

The UI used for editing attachment details has been completely redesigned, allowing for a normally-size comment box to be used when commenting on attachments, and allowing nearly the entire screen width to be used when doing code reviews or editing an attachment as a comment.

Thanks to Guy Pyrzak for his excellent work on this UI redesign.

Autocomplete for Users and Keywords

Once you type at least three characters in any field that can contain a user (including the CC, QA Contact, or Assignee fields), a list will appear containing all of the users whose real names or usernames match what you are typing. Your Bugzilla must have all of the optional Perl modules required for JSON-RPC support installed, though, in order for this feature to work. Also, this feature will be much faster on installations that run under mod_perl than it will be on other installations.

There is also a similar autocomplete for the Keywords field. The Keywords autocomplete does not require JSON-RPC.

General Usability Improvements

In addition to the enhancements listed above, there have been many improvements made across the Bugzilla user interface. For a list of specific enhancements that were significant, see the Other Enhancements and Changes section.

New Default Status Workflow

For new installations of Bugzilla, the default set of statuses will now be:

And the UNCONFIRMED status will be enabled by default in all products.

On upgrade, existing installations will not be affected--you will retain your existing status workflow. However, we strongly recommend that you update your existing workflow to the new one, using a special tool we've included, contrib/convert-workflow.pl, which you can run after you use checksetup.pl to upgrade. The whineatnews.pl and bugzilla-submit scripts will probably not work properly if you continue to use the old workflow (though most other parts of Bugzilla will still function normally).

For more information about the workflow and our rationale for changing it, see the blog post about it and the bug where the change was made.

"Last Search" Now Remembers Multiple Searches

At the top of every bug in Bugzilla, there are links that look like: "First", "Last", "Prev", "Next", and "Show last search results". In earlier versions of Bugzilla, if you did two separate searches in separate windows, these links would only work for the last search you did. Now, Bugzilla will "remember" which search result you came from and give you the right "last search results" or "next bug" from that list, instead of always using your most recent search.

There are still some situations where Bugzilla will have to "guess" which search you are trying to navigate through, but it does its best to get it right.

Cross-Domain WebServices with JSONP

Bugzilla now supports making WebService calls from another domain, inside of a web browser, thanks to support for JSONP. This will allow for web "mash-ups" to use Bugzilla data. When using JSONP, you may only call functions that get data, you may not call functions that change data.

For more details, see the JSONP section of the JSON-RPC WebService documentation.

Major WebService Enhancements

The WebService has been expanded considerably. The WebService should now be able to do everything with bugs that you can do via the web interface, including updating bugs, adding attachments, and getting attachment data. For specifics, see the WebService Changes section of these release notes.

Mandatory Custom Fields

You can now specify that certain custom fields are "mandatory", meaning that they must have a value when a bug is filed, and they can never be empty after that.

Voting Is Now An Extension

All of the code for voting in Bugzilla has been moved into an extension, called "Voting", in the extensions/Voting/ directory. To enable it, you must remove the disabled file from that directory, and run checksetup.pl.

In a future version of Bugzilla, the Voting extension will be moved outside of the Bugzilla core code, so we are looking for somebody who has an interest in the Voting system and would like to maintain it as a separate extension. There are many enhancement requests that have been made against the Voting system, and the best way for those to get addressed is for somebody to step up and offer to maintain the system outside of Bugzilla's core code.

Users Get New CSS and Javascript Automatically

In past versions of Bugzilla, if you changed Bugzilla's CSS or Javascript files, then every user of Bugzilla would have to clear their cache in order to get the updated files. Now, if you are using Apache as your webserver and you have the optional Apache modules installed and enabled, users will automatically get every new version of Bugzilla's Javascript and CSS without having to clear their caches.

This feature also gives a slight performance speedup to Bugzilla in some cases, and so we recommend that all administrators install and enable the optional Apache modules if possible.

Many New Hooks

Many new code hooks have been added for use by Extensions, in Bugzilla 4.0. Now Extensions can access and modify nearly every part of Bugzilla.

New Apache Configuration

If you run Bugzilla under Apache (as most people do), you most likely require a new Apache configuration for this version of Bugzilla. See the Notes On Upgrading From a Previous Version section for details.

Notes On Upgrading From a Previous Version

IMPORTANT: Apache Configuration Change

mod_cgi

If you run Bugzilla under mod_cgi (this is the most common configuration, involving a <Directory> block in your Apache config file), you will need to update the configuration of Apache for Bugzilla. In particular, this line in the Bugzilla <Directory> block:

AllowOverride Limit

needs to become:

AllowOverride Limit FileInfo Indexes

For full details on how to configure Apache for Bugzilla, see the Configuration section of the Bugzilla Guide.

mod_perl

If your Bugzilla runs under mod_perl, the required Apache configuration is now simpler. The line that used to look like:

PerlSwitches -w -T -I/var/www/html/bugzilla -I/var/www/html/bugzilla/lib

Now should be only:

PerlSwitches -w -T

The PerlConfigRequire line should stay the same, however.

New .htaccess file

In previous versions of Bugzilla, there was a file in Bugzilla's root directory called ".htaccess" that was generated by checksetup.pl. This file is now shipped with Bugzilla instead of being generated during installation.

If you update via CVS or bzr, you will get a message that your existing .htaccess file conflicts with the new one. You must remove your existing .htaccess file and use the new one instead. Continuing to use your old .htaccess file will cause certain new features of Bugzilla to not work properly, and may also lead to security issues for your system in the future.

Code Changes Which May Affect Customizations and Extensions

Bugzilla 3.6 Release Notes

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!

New Features and Improvements

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:

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:

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

Enhancements for Administrators and Developers

WebService Changes

Outstanding Issues

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.

New Features and Improvements

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.

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.

New Features and Improvements

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:

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!

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.

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.

New Features and Improvements

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:

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!

How to Upgrade From An Older Version

Notes For Upgraders

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};.
