Project Description

This plugin is based on earlier plugins. Its main innovation is to make multiple branches available, the way Trac normally does.

Features

Repository views

Supports all major Trac views and “changeset:” notation.

Allows a collection of branches to be treated as a “trac repository”, regardless of whether they are related or in the same bzr repository.

Follows symlinks to branches.

Wiki Macros

Branches

The plugin provides a macro called [[Branches]] to list all available branches, together with some information about them, like the current revision number and the time of the last commit.

Installation

Basically the Plugins section of the Trac Guide applies to the installation of trac-bzr as well. It gives you several options how to install a plugin.

System-wide using easy_install

Executing the command “easy_install TracBzr” as root should install the plugin system-wide, making it available to all trac environments on that system.

Per-environment using plugin egg file

You can download the egg file corresponding to your python version and place it in the plugins directory of a Trac environment.

Building from source

If you want to build trac-bzr from source, you can either grab a source release tarball or a checkout of a development branch. Many development branches are listed on launchpad. Once you have obtained such a source tree, execute “python setup.py install” to install the plugin system-wide, or “python setup.py bdist_egg” to obtain an egg file for installation in a single Trac environment.

Requirements

In order to function properly, trac-bzr requires the packages listed below.

These dependencies are not handled by setuptools, because otherwise the plugin would fail to load if one of the dependencies wasn’t installed with setuptools or similar.

Python 2.4
This plugin uses bzrlib directly, so it requires Python 2.4 or greater.
Trac 0.10
Some features may only work with Trac 0.11 or even Trac 0.12.
Bazaar 2.0
This plugin should work with Bazaar 2.0. Earlier versions may or may not work.

Configuration

To configure trac-bzr, you’ll have to edit the trac.ini file of your Trac environment.

Required configuration

After installing, you’ll want to set the following values:

[components]
tracbzr.* = enabled

[trac]
repository_type = bzr
repository_dir = /path/to/collection/of/bzr/branches

components

This should include “tracbzr.* = enabled” to enable all features provided by the plugin. As an alternative, you can enable or disable specific components providing specific features, e.g. in order to disable the wiki macro provider. Use the Trac web admin plugin interface (Trac 0.11 or later) or have a look at the sources to find out which components are available.

repository_dir

This should point at the directory containing your branches. This directory does not have to be a repository. trac-bzr doesn’t require branches to be related, though that is permitted, of course.

repository_type

This should be “bzr”.

Optional configuration

There are some optional settings you can configure for trac-bzr. If you do not specify them, the following defaults will be used instead:

[tracbzr]
primary_branches = trunk
include_sideline_changes = True

primary_branches

This is a comma-separated ordered list of the main branches of your project. You may also specify glob patterns in this list to match multiple branches.

Note that the pattern must match from the root of repository_dir, so if you set it to e.g. a directory containing sub-directories which in turn contain branches, you should set primary_branches to */BRANCH.

The Branches wiki macro will list branches in the order specified by this list. The timeline view will try to associate changesets with branches in the specified order. In both cases, branches not matched by any list item will be inserted at the end of the list, as if you had ended the list with ,*. Branches matched by a single list item will be sorted alphabetically.

include_sideline_changes

This boolean flag selects whether or not sideline changes, i.e. those denoted with dotted revision numbers, are included in the list of all changes. This affects the output of the get_changesets method, which in turn influences the events listed in the timeline view.

Note that there might be other plugins using that information as well, so there might be other components beside the timeline view that get affected by this setting.

Performance

Some user-level operations are rather slow, because Trac’s assumptions about which repository operations are cheap vs expensive doesn’t match Bazaar’s design.

Revision numbers

One of the problems is the mapping between revision identifiers and revision numbers. The Bazaar Revision Numbering Cache Plugin might help for this problem, although it’s experimental and hasn’t been tested with trac-bzr extensively enough. Feedback welcome.

Last modifications

Another problem is that bzr has a different idea about the last modification of a directory. In svn, any modifications of directory contents is said to modify the dir as well. In bzr, only changes to the set of files in a directory are counted.

Investigations are in progress about how to solve this problem, probably through the use of caches.

Limitations

Bogus changesets

This plugin introduces the bogus changeset “current:”, which is used as the last-revision for directories that are not branches. It also provides “null:”, which is part of Bazaar’s theoretical model, but usually hidden.

Hidden nested branches

Because Trac, like Subversion, doesn’t differentiate between “source file namespace” and “branch namespace”, it is impossible to view branches whose directories are directly inside other branches’ directories.

Revision order

If two changesets are not related to one another by some direct ancestry, i.e. if neither one is an ancestor of the other, then revisions are sorted by timestamp instead. In case of a clock skew this can lead to inconcistent results, as transitivity isn’t guaranteed for this approach.

Bracket syntax

Trac does not to recognize bzr revision strings in its bracket notation, e.g. [tree,25]. However, you can use the changeset notation instead, e.g. changeset:tree,25.

Revision specification format

Since Trac repository queries don’t give trac-bzr enough context, revisions have to be specified and are presented in the format PATH_TO_BRANCH,REV where PATH_TO_BRANCH is the path to branch (or object within the branch like directory or file) relative to repository_dir, with slashes (‘/’) replaced with commas (‘,’).

This is visible when browsing the branches via Trac’s source browser and this is also what you have to use in TracLinks.

This may be improved in the future when trac-bzr adds proper support for the multiple repository interfaces added in Trac 0.12.

In the meantime, if you have an urgent need to address that and are able to spend some time implementing it, have a look at HACKING document for possible approaches in Trac 0.11 and below.

File encoding

Because at the moment Bazaar does not store information about encoding of text files, you may want to change the default character set used by trac. By default trac use encoding iso-8895-15 to show content of your files. If you need to change this option, you need to edit trac.ini of your project. In section “trac” you need to change parameter named “default_charset”. E.g. for russian files:

[trac]
default_charset = cp1251
