+# bugzilla.py - bugzilla integration for mercurial

+
+'''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.
