Post-PR merge hook

[Josh Baird]

My repositories use custom hooks in post-recieve.d/ that essentially SSH to a production machine and executes 'git fetch' against the Stash git repo. I have a need to trigger this same script after a PR has been merged.

How can I do this?

Hi Josh,

Git itself doesn't have any hooks that will be able to help here (just FYI there is a merge hook in Git, but the way Stash does the PR merges it will never fire).

One way to handle this would be to write a Java plugin that listens for a PR merge and invokes your custom script directly. This would be relatively easy but does require some knowledge of Java.

Personally, if it were me, I would actually use webhooks to notify a simple listener hook on your production machine and do the fetch that way. Either that or just set up a cron job to fetch every X seconds/minutes.

Does that help?

Use webhooks to notify a simple listening? Can you please explain that a bit more?

Hi Josh,

Sorry bad English. Have fixed.

But basically you could run a very simple http server in whatever language you like, which listens for JSON that Stash would send and depending on whether the master branch has been modified (described in the payload) then you could do the fetch from there.

Cheers,

Atlassian? Anyone?
