'''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 hook does not change bug status.

Three basic modes of access to Bugzilla are provided:

1. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or later.

2. Check data via the Bugzilla XMLRPC interface and submit bug change
   via email to Bugzilla email interface. Requires Bugzilla 3.4 or later.

2. 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.

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.

Access via XMLRPC/email behaves 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 recognised by Bugzilla as a Bugzilla
user, the Bugzilla username and password used to log into Bugzilla are
used instead as the source of the comment.

Configuration items common to all access modes:

bugzilla.version
  This access type to use. Values recognised are:
  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 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.

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 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.

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
``bugmail@my-project.org`` with password ``plugh``. It is used with a
collection of Mercurial repositories in ``/var/local/hg/repos/``. ::

    [bugzilla]
    bzurl=http://my-project.org/bugzilla
    user=bugmail@my-project.org
    password=plugh
    version=xmlrpc

    [web]
    baseurl=http://my-project.org/hg

XMLRPC+email example configuration. This uses the Bugzilla at
``http://my-project.org/bugzilla``, logging in as user
``bugmail@my-project.org`` wityh password ``plugh``. It is used with a
collection of Mercurial repositories in ``/var/local/hg/repos/``. Bug
comments are sent to the Bugzilla email address
``bugzilla@my-project.org``. ::

    [bugzilla]
    user=bugmail@my-project.org
    password=plugh
    version=xmlrpc
    bzemail=bugzilla@my-project.org

    [web]
    baseurl=https://dev.laicatc.com/hg
    bugzillaurl=https://dev.laicatc.com/bugzilla

MySQL example configuration. This 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. The MySQL database is on
``localhost``, the Bugzilla database name is ``bugs`` and MySQL is
accessed with MySQL username ``bugs`` password ``XYZZY``. ::

    [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

All the above 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.
