How to add Mercurial churn extension in TeamCity

Question

I'd like to generate the hg churn report in my TeamCity build, but the Churn extension is not enabled by default in Hg. On my local box, I just add churn to the [extensions] section of mercurial.ini.

Where do I put a system wide mercurial.ini so the teamcity build agent can find it and see the extension addition? Or, better yet, is there a way to add extensions in the build step or in the TeamCity setup?

Answer 1

If you are able to provide TeamCity command line arguments for mercurial, you should be able to use the --config option and enable the extension with a direct path:

hg --config extensions.churn=/path/to/churn.py churn -r 200:300 -a test.py

That said, I believe that churn is included, though not enabled, in the default install so you could first try:

hg --config extensions.hgext.churn= churn -r 200:300 

That worked for me locally.

This is based on reading the Churn Wiki and using hg help to find the --config option.
