| 5 | +# This script contains porcelain and porcelain byproducts. |
| 6 | +# It's Python because the Python standard libraries avoid portability/security |
| 7 | +# issues raised by callouts in the ancestral Perl and sh scripts. It should |
| 8 | +# be compatible back to Python 2.1.5 |
| 9 | +# |
| 10 | +# usage: ciabot.py [-V] [-n] [-p projectname] [refname [commits...]] |
| 11 | +# |
| 12 | +# This script is meant to be run either in a post-commit hook or in an |
| 13 | +# update hook. If there's nothing unusual about your hosting setup, |
| 14 | +# you can specify the project name with a -p option and avoid having |
| 15 | +# to modify this script. Try it with -n to see the notification mail |
| 16 | +# dumped to stdout and verify that it looks sane. With -V it dumps its |
| 17 | +# version and exits. |
| 18 | +# |
| 19 | +# In post-commit, run it without arguments (other than possibly a -p |
| 20 | +# option). It will query for current HEAD and the latest commit ID to |
| 21 | +# get the information it needs. |
| 22 | +# |
| 23 | +# In update, call it with a refname followed by a list of commits: |
| 24 | +# You want to reverse the order git rev-list emits becxause it lists |
| 25 | +# from most recent to oldest. |
| 26 | +# |
| 27 | +# /path/to/ciabot.py ${refname} $(git rev-list ${oldhead}..${newhead} | tac) |
| 28 | +# |

| 30 | +# until timeout when the CIA XML-RPC server is down. |
