 '''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 comment is formatted using
 the Mercurial template mechanism.
 
 The bug references can optionally include an update for Bugzilla of the
 hours spent working on the bug. Bugs can also be marked fixed.
 
 Four basic modes of access to Bugzilla are provided:
 
 1. Access via the Bugzilla REST-API. Requires bugzilla 5.0 or later.
 
 2. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or later.
 
 3. Check data via the Bugzilla XMLRPC interface and submit bug change
    via email to Bugzilla email interface. Requires Bugzilla 3.4 or later.
 
 4. Writing directly to the Bugzilla database. Only Bugzilla installations
    using MySQL are supported. Requires Python MySQLdb.
 
 Writing directly to the database is susceptible to schema changes, and
 relies on a Bugzilla contrib script to send out bug change
 notification emails. This script runs as the user running Mercurial,
 must be run on the host with the Bugzilla install, and requires
 permission to read Bugzilla configuration details and the necessary
 MySQL user and password to have full access rights to the Bugzilla
 database. For these reasons this access mode is now considered
 deprecated, and will not be updated for new Bugzilla versions going
 forward. Only adding comments is supported in this access mode.
 
 Access via XMLRPC needs a Bugzilla username and password to be specified
 in the configuration. Comments are added under that username. Since the
 configuration must be readable by all Mercurial users, it is recommended
 that the rights of that user are restricted in Bugzilla to the minimum
 necessary to add comments. Marking bugs fixed requires Bugzilla 4.0 and later.
 
 Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends
 email to the Bugzilla email interface to submit comments to bugs.
 The From: address in the email is set to the email address of the Mercurial
 user, so the comment appears to come from the Mercurial user. In the event
 that the Mercurial user email is not recognized by Bugzilla as a Bugzilla
 user, the email associated with the Bugzilla username used to log into
 Bugzilla is used instead as the source of the comment. Marking bugs fixed
 works on all supported Bugzilla versions.
 
 Access via the REST-API needs either a Bugzilla username and password
 or an apikey specified in the configuration. Comments are made under
 the given username or the user associated with the apikey in Bugzilla.
 
 Configuration items common to all access modes:
 
 bugzilla.version
   The access type to use. Values recognized are:
 
   :``restapi``:      Bugzilla REST-API, Bugzilla 5.0 and later.
   :``xmlrpc``:       Bugzilla XMLRPC interface.
   :``xmlrpc+email``: Bugzilla XMLRPC and email interfaces.
   :``3.0``:          MySQL access, Bugzilla 3.0 and later.
   :``2.18``:         MySQL access, Bugzilla 2.18 and up to but not
                      including 3.0.
   :``2.16``:         MySQL access, Bugzilla 2.16 and up to but not
                      including 2.18.
 
 bugzilla.regexp
   Regular expression to match bug IDs for update in changeset commit message.
   It must contain one "()" named group ``<ids>`` containing the bug
   IDs separated by non-digit characters. It may also contain
   a named group ``<hours>`` with a floating-point number giving the
   hours worked on the bug. If no named groups are present, the first
   "()" group is assumed to contain the bug IDs, and work time is not
   updated. The default expression matches ``Bug 1234``, ``Bug no. 1234``,
   ``Bug number 1234``, ``Bugs 1234,5678``, ``Bug 1234 and 5678`` and
   variations thereof, followed by an hours number prefixed by ``h`` or
   ``hours``, e.g. ``hours 1.5``. Matching is case insensitive.
 
 bugzilla.fixregexp
   Regular expression to match bug IDs for marking fixed in changeset
   commit message. This must contain a "()" named group ``<ids>` containing
   the bug IDs separated by non-digit characters. It may also contain
   a named group ``<hours>`` with a floating-point number giving the
   hours worked on the bug. If no named groups are present, the first
   "()" group is assumed to contain the bug IDs, and work time is not
   updated. The default expression matches ``Fixes 1234``, ``Fixes bug 1234``,
   ``Fixes bugs 1234,5678``, ``Fixes 1234 and 5678`` and
   variations thereof, followed by an hours number prefixed by ``h`` or
   ``hours``, e.g. ``hours 1.5``. Matching is case insensitive.
 
 bugzilla.fixstatus
   The status to set a bug to when marking fixed. Default ``RESOLVED``.
 
 bugzilla.fixresolution
   The resolution to set a bug to when marking fixed. Default ``FIXED``.
 
 bugzilla.style
   The style file to use when formatting comments.
 
 bugzilla.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}``
 
 bugzilla.strip
   The number of path separator characters to strip from the front of
   the Mercurial repository path (``{root}`` in templates) to produce
   ``{webroot}``. For example, a repository with ``{root}``
   ``/var/local/my-project`` with a strip of 2 gives a value for
   ``{webroot}`` of ``my-project``. Default 0.
 
 web.baseurl
   Base URL for browsing Mercurial repositories. Referenced from
   templates as ``{hgweb}``.
 
 Configuration items common to XMLRPC+email and MySQL access modes:
 
 bugzilla.usermap
   Path of file containing Mercurial committer email to Bugzilla user email
   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 email to Bugzilla user email. See also ``bugzilla.usermap``.
 Contains entries of the form ``committer = Bugzilla user``.
 
 XMLRPC and REST-API access mode configuration:
 
 bugzilla.bzurl
   The base URL for the Bugzilla installation.
   Default ``http://localhost/bugzilla``.
 
 bugzilla.user
   The username to use to log into Bugzilla via XMLRPC. Default
   ``bugs``.
 
 bugzilla.password
   The password for Bugzilla login.
 
 REST-API access mode uses the options listed above as well as:
 
 bugzilla.apikey
   An apikey generated on the Bugzilla instance for api access.
   Using an apikey removes the need to store the user and password
   options.
 
 XMLRPC+email access mode uses the XMLRPC access mode configuration items,
 and also:
 
 bugzilla.bzemail
   The Bugzilla email address.
 
 In addition, the Mercurial email settings must be configured. See the
 documentation in hgrc(5), sections ``[email]`` and ``[smtp]``.
 
 MySQL access mode configuration:
 
 bugzilla.host
   Hostname of the MySQL server holding the Bugzilla database.
   Default ``localhost``.
 
 bugzilla.db
   Name of the Bugzilla database in MySQL. Default ``bugs``.
 
 bugzilla.user
   Username to use to access MySQL server. Default ``bugs``.
 
 bugzilla.password
   Password to use to access MySQL server.
 
 bugzilla.timeout
   Database connection timeout (seconds). Default 5.
 
 bugzilla.bzuser
   Fallback Bugzilla user name to record comments with, if changeset
   committer cannot be found as a Bugzilla user.
 
 bugzilla.bzdir
    Bugzilla install directory. Used by default notify. Default
    ``/var/www/html/bugzilla``.
 
 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".
 
 Activating the extension::
 
     [extensions]
     bugzilla =
 
     [hooks]
     # run bugzilla hook on every change pulled or pushed in here
     incoming.bugzilla = python:hgext.bugzilla.hook
 
 Example configurations:
 
 XMLRPC example configuration. This uses the Bugzilla at
 ``http://my-project.org/bugzilla``, logging in as user
 ``[e-mail]`` with password ``plugh``. It is used with a
 collection of Mercurial repositories in ``/var/local/hg/repos/``,
 with a web interface at ``http://my-project.org/hg``. ::
 
     [bugzilla]
     bzurl=http://my-project.org/bugzilla
     user=[e-mail]
     password=plugh
     version=xmlrpc
     template=Changeset {node|short} in {root|basename}.
              {hgweb}/{webroot}/rev/{node|short}\\n
              {desc}\\n
     strip=5
 
     [web]
