How to make mercurial run script on push?

Question

I have a server which hosts a mercurial repository with hgwebdir. Is it possible to make mercurial to run a script when someone pushes to this repository?
Currently I use a script that checks the repository state every few minutes, but this is obviously an ugly solution.

Answer 1

You have to add a hook to your Mercurial server:

• Edit .hg/hgrc (or mercurial.ini on Windows)
• Add or edit the [hooks] section
• Associate a shell command to the hook you are interested in (in your case, the changegroup hook)

Look at Handling repository events with hooks in the Mercurial red-bean book for more details.
