"""Provides a shorthand for referring to bugs on a variety of bug trackers.
28
'commit --fixes' stores references to bugs as a <bug_url> -> <bug_status>
29
mapping in the properties for that revision.
31
However, it's inconvenient to type out full URLs for bugs on the command line,
32
particularly given that many users will be using only a single bug tracker per
35
Thus, this module provides a registry of types of bug tracker (e.g. Launchpad,
36
Trac). Given an abbreviated name (e.g. 'lp', 'twisted') and a branch with
37
configuration information, these tracker types can return an instance capable
38
of converting bug IDs into URLs.
43
"""When making a commit, metadata about bugs fixed by that change can be
44
recorded by using the --fixes option. For each bug marked as fixed, an
45
entry is included in the 'bugs' revision property stating '<url> <status>'.
46
(The only ``status`` value currently supported is ``fixed.``)
47
Support for Launchpad's central bug tracker is built in. For other bug
48
trackers, configuration is required in advance so that the correct URL
51
In addition to Launchpad, Bazaar directly supports the generation of
52
URLs appropriate for Bugzilla and Trac. If your project uses a different
53
bug tracker, it is easy to add support for it.
54
If you use Bugzilla or Trac, then you only need to set a configuration
55
variable which contains the base URL of the bug tracker. These options
56
can go into ``bazaar.conf``, ``branch.conf`` or into a branch-specific
57
configuration section in ``locations.conf``. You can set up these values
58
for each of the projects you work on.
60
Note: As you provide a short name for each tracker, you can specify one or
61
more bugs in one or more trackers at commit time if you wish.

bugzilla_<tracker_abbreviation>_url
64
-----------------------------------
66
If present, the location of the Bugzilla bug tracker referred to by
67
<tracker_abbreviation>. This option can then be used together with ``bzr commit
68
--fixes`` to mark bugs in that tracker as being fixed by that commit. For
71
bugzilla_squid_url = http://www.squid-cache.org/bugs
73
would allow ``bzr commit --fixes squid:1234`` to mark Squid's bug 1234 as
76
trac_<tracker_abbrevation>_url
77
------------------------------
79
If present, the location of the Trac instance referred to by

81
--fixes`` to mark bugs in that tracker as being fixed by that commit. For

which will be replaced by a specific bug ID. This option can then be used
95
together with ``bzr commit --fixes`` to mark bugs in that tracker as being
96
fixed by that commit. For example::
