How to access the commit message in pre-receive hook

Jim Murphy

Hi,

I am attempting to write a pre-recieve hook in Stash 2.2 where I check the formatting of the commit message. I have been unsuccessful at accessing the message and am hoping I could get some guidance or even an example.

Thanks,

-Jim

Hi Jim,

These are the steps involved for what you need:

1. Create a PreReceiveRepositoryHook as detailed here: https://developer.atlassian.com/stash/docs/latest/how-tos/repo-hook-examples/pre-receive-no-config.html
2. Iterate over the RefChanges (as shown in the example above). The pre receive hook does not receive a collection of changesets, but rather a list of the refs that have changed. There can be multiple refs that have changed in one push (eg pushing multiple commits to multiple branches at once)
3. For each RefChange, use the fromHash and toHash to extract the individual changesets: https://developer.atlassian.com/static/javadoc/stash/latest/api/reference/com/atlassian/stash/repository/RefChange.html
4. Using HistoryService.getChangesetsBetween stream a list of changesets from RefChange.getFromHash and RefChange.getToHash
5. For each of these changesets, validate the message as you need.

Hope that helps,

Seb
