7 # This is a version 3.x of ciabot.sh; use -V to find the exact
8 # version. Versions 1 and 2 were shipped in 2006 and 2008 and are not
9 # version-stamped. The version 2 maintainer has passed the baton.
11 # Note: This script should be considered obsolete.
12 # There is a faster, better-documented rewrite in Python: find it as ciabot.py
13 # Use this only if your hosting site forbids Python hooks.
15 # Originally based on Git ciabot.pl by Petr Baudis.
16 # This script contains porcelain and porcelain byproducts.
18 # usage: ciabot.sh [-V] [-n] [-p projectname] [refname commit]
20 # This script is meant to be run either in a post-commit hook or in an
21 # update hook. If there's nothing unusual about your hosting setup,
22 # you can specify the project name with a -p option and avoid having
23 # to modify this script. Try it with -n first to see the notification
24 # mail dumped to stdout and verify that it looks sane. Use -V to dump
25 # the version and exit.
27 # In post-commit, run it without arguments (other than possibly a -p
28 # option). It will query for current HEAD and the latest commit ID to
29 # get the information it needs.
31 # In update, you have to call it once per merged commit:
33 # refname=$1
34 # oldhead=$2
35 # newhead=$3
36 # for merged in $(git rev-list ${oldhead}..${newhead} | tac) ; do
37 # /path/to/ciabot.bash ${refname} ${merged}
38 # done
40 # The reason for the tac call ids that git rev-list emits commits from
41 # most recent to least - better to ship notifactions from oldest to newest.
43 # Note: this script uses mail, not XML-RPC, in order to avoid stalling
44 # until timeout when the CIA XML-RPC server is down.
48 # The project as known to CIA. You will either want to change this
49 # or set the project name with a -p option.
