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!

Enhancements For Users

Enhancements For Administrators

Enhancements for Localizers (or Localized Installations)

Steps For Upgrading

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.

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 withBugzilla. 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 [email protected] 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};.
