# bugzilla.py - bugzilla integration for mercurial # # Copyright 2006 Vadim Gelfer <vadim.gelfer@gmail.com> # # This software may be used and distributed according to the terms # of the GNU General Public License, incorporated herein by reference. '''Bugzilla integration 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. Configuring the extension: [bugzilla] 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 from 3.0 onwards, and '2.16' for versions prior to 3.0. bzuser Fallback Bugzilla user name to record comments with, if changeset committer cannot be found as a Bugzilla user. notify The command to run to get Bugzilla to send bug change notification emails. Substitutes one string parameter, the bug ID. Default 'cd /var/www/html/bugzilla && ' './processmail %s nobody@nowhere.com'. 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. [usermap] Any entries in this section specify mappings of Mercurial committer ID to Bugzilla user ID. See also [bugzilla].usermap. "committer"="Bugzilla user" [web] baseurl Base URL for browsing Mercurial repositories. Reference from templates as {hgweb}. Activating the extension: [extensions] hgext.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.
