# hook extension to update comments of bugzilla bugs when changesets
# that refer to bugs by id are seen. this hook does not change bug
# status, only comments.
#
# to configure, add items to '[bugzilla]' section of hgrc.
#
# to use, configure bugzilla extension and enable like this:
#
# [extensions]
# hgext.bugzilla =
#
# [hooks]
# # run bugzilla hook on every change pulled or pushed in here
# incoming.bugzilla = python:hgext.bugzilla.hook
#
# config items:
#
# REQUIRED:
# host = bugzilla # mysql server where bugzilla database lives
# password = ** # user's password
# version = 2.16 # version of bugzilla installed
#
# OPTIONAL:
# bzuser = ... # bugzilla user id to record comments with
# db = bugs # database to connect to
# notify = ... # command to run to get bugzilla to send mail
# regexp = ... # regexp to match bug ids (must contain one "()" group)
# strip = 0 # number of slashes to strip for url paths
# style = ... # style file to use when formatting comments
# template = ... # template to use when formatting comments
# timeout = 5 # database connection timeout (seconds)
# user = bugs # user to connect to database as
# [web]
# baseurl = http://hgserver/... # root of hg web site for browsing commits
