Raymond # Assistance and review by Petr Baudis, author of ciabot.pl, # is gratefully acknowledged. # # This is a version 3.x of ciabot.sh; use -V to find the exact # version. Versions 1 and 2 were shipped in 2006 and 2008 and are not # version-stamped. The version 2 maintainer has passed the baton. # # Note: This script should be considered obsolete. # There is a faster, better-documented rewrite in Python: find it as ciabot.py # Use this only if your hosting site forbids Python hooks. # It requires: git(1), hostname(1), cut(1), sendmail(1), and wget(1). # # Originally based on Git ciabot.pl by Petr Baudis. # This script contains porcelain and porcelain byproducts. # # usage: ciabot.sh [-V] [-n] [-p projectname] [refname commit] # # This script is meant to be run either in a post-commit hook or in an # update hook. Try it with -n to see the notification mail dumped to # stdout and verify that it looks sane. With -V it dumps its version # and exits. # # In post-commit, run it without arguments. It will query for # current HEAD and the latest commit ID to get the information it # needs. # # In update, you have to call it once per merged commit: # # refname=$1 # oldhead=$2 # newhead=$3 # for merged in $(git rev-list ${oldhead}..${newhead} | tac) ; do # /path/to/ciabot.sh ${refname} ${merged} # done # # The reason for the tac call is that git rev-list emits commits from # most recent to least - better to ship notifactions from oldest to newest. # # Configuration variables affecting this script: # # ciabot.project = name of the project # ciabot.repo = name of the project repo for gitweb/cgit purposes # ciabot.revformat = format in which the revision is shown # # ciabot.project defaults to the directory name of the repository toplevel. # ciabot.repo defaults to ciabot.project lowercased. # # This means that in the normal case you need not do any configuration at all, # but setting the project name will speed it up slightly. # # The revformat variable may have the following values # raw -> full hex ID of commit # short -> first 12 chars of hex ID # describe = -> describe relative to last tag, falling back to short # The default is 'describe'. # # Note: the shell ancestors of this script used mail, not XML-RPC, in # order to avoid stalling until timeout when the CIA XML-RPC server is # down. It is unknown whether this is still an issue in 2010, but # XML-RPC would be annoying to do from sh in any case. (XML-RPC does # have the advantage that it guarantees notification of multiple commits # shpped from an update in their actual order.) # # The project as known to CIA.
