[users at bb.net] Looking for help on creating Mercurial repo change hook with Buildbot

Hi Pierre and all,

So, I was able to get the base change hook enabled. And verified it 
using the post_build_request.py which I found in the following directory:


Unfortunately, when I try to setup the change hook for a Mercurial 
repository, nothing is sent to Buildbot. And I see no record of the 
change hook in the Buildbot's twisted.log.

Following the directions and documentation in the following:

* In the Buildbot manual about how to setup a Mercurial Change hook:

* Also, using the inline documentation in the post_build_request.py

I did the following:

1) Copied the post_build_request.py into the .hg folder of the repo I 
wanted to notify Buildbot of any changes

2) Modified the repo's hgrc by adding the following to it:

changegroup.buildbot = python:.hg/hgbuildbot.py:hook

venv = /srv/home/.virtualenv/lib/python2.7/site-packages
master = http://<ip address of Buildbot>:8020/change_hook/base
branch = default
project = my-project-name

Note: I tried removing the 'branch' and 'project' parameters to no 
effect. Also, I tried setting the master to the following by removing 
the "http://":

master = <ip address of Buildbot>:8020/change_hook/base

3) Ensured that hgbuilder.py had the executable permission.

And nothing got to Buildbot as far as I could tell when I:

a) Did a commit of a change

b) Then a push of the change

Any help or advice would be appreciated.
