'''hooks for integrating with the Bugzilla bug tracker
This hook extension adds comments on bugs in Bugzilla when changesets
that refer to bugs by Bugzilla ID are seen. The hook does not change
bug status.
The hook updates the Bugzilla database directly. Only Bugzilla
installations using MySQL are supported.
The hook relies on a Bugzilla script to send bug change notification
emails. That script changes between Bugzilla versions; the
'processmail' script used prior to 2.18 is replaced in 2.18 and
subsequent versions by 'config/sendbugmail.pl'. Note that these will
be run by Mercurial as the user pushing the change; you will need to
ensure the Bugzilla install file permissions are set appropriately.
The extension is configured through three different configuration
sections. These keys are recognized in the [bugzilla] section:
host
Hostname of the MySQL server holding the Bugzilla database.
db
Name of the Bugzilla database in MySQL. Default 'bugs'.
user
Username to use to access MySQL server. Default 'bugs'.
password
Password to use to access MySQL server.
timeout
Database connection timeout (seconds). Default 5.
version
Bugzilla version. Specify '3.0' for Bugzilla versions 3.0 and later,
'2.18' for Bugzilla versions from 2.18 and '2.16' for versions prior
to 2.18.
bzuser
Fallback Bugzilla user name to record comments with, if changeset
committer cannot be found as a Bugzilla user.
bzdir
Bugzilla install directory. Used by default notify. Default
'/var/www/html/bugzilla'.
notify
The command to run to get Bugzilla to send bug change notification
emails. Substitutes from a map with 3 keys, 'bzdir', 'id' (bug id)
and 'user' (committer bugzilla email). Default depends on version;
from 2.18 it is "cd %(bzdir)s && perl -T contrib/sendbugmail.pl
%(id)s %(user)s".
regexp
Regular expression to match bug IDs in changeset commit message.
Must contain one "()" group. The default expression matches 'Bug
1234', 'Bug no. 1234', 'Bug number 1234', 'Bugs 1234,5678', 'Bug
1234 and 5678' and variations thereof. Matching is case insensitive.
style
The style file to use when formatting comments.
template
Template to use when formatting comments. Overrides style if
specified. In addition to the usual Mercurial keywords, the
extension specifies::
{bug} The Bugzilla bug ID.
{root} The full pathname of the Mercurial repository.
{webroot} Stripped pathname of the Mercurial repository.
{hgweb} Base URL for browsing Mercurial repositories.
Default 'changeset {node|short} in repo {root} refers '
'to bug {bug}.\\ndetails:\\n\\t{desc|tabindent}'
strip
The number of slashes to strip from the front of {root} to produce
{webroot}. Default 0.
usermap
Path of file containing Mercurial committer ID to Bugzilla user ID
mappings. If specified, the file should contain one mapping per
line, "committer"="Bugzilla user". See also the [usermap] section.
The [usermap] section is used to specify mappings of Mercurial
committer ID to Bugzilla user ID. See also [bugzilla].usermap.
"committer"="Bugzilla user"
Finally, the [web] section supports one entry:
baseurl
Base URL for browsing Mercurial repositories. Reference from
templates as {hgweb}.
Activating the extension::
[extensions]
bugzilla =
[hooks]
# run bugzilla hook on every change pulled or pushed in here
incoming.bugzilla = python:hgext.bugzilla.hook
Example configuration:
This example configuration is for a collection of Mercurial
repositories in /var/local/hg/repos/ used with a local Bugzilla 3.2
installation in /opt/bugzilla-3.2. ::
[bugzilla]
host=localhost
password=XYZZY
version=3.0
bzuser=unknown@domain.com
bzdir=/opt/bugzilla-3.2
template=Changeset {node|short} in {root|basename}.
{hgweb}/{webroot}/rev/{node|short}\\n
{desc}\\n
strip=5
[web]
baseurl=http://dev.domain.com/hg
[usermap]
user@emaildomain.com=user.name@bugzilladomain.com
Commits add a comment to the Bugzilla bug record of the form::
Changeset 3b16791d6642 in repository-name.
http://dev.domain.com/hg/repository-name/rev/3b16791d6642
Changeset commit comment. Bug 1234.
