pre-receive/update hook: how to know forced push?

Alexey Shumkin· Apr 10, 2012, 13:59 UTC · lore

Hi, guys!

How to know in pre-receive hook that commit has been pushed with --force option?

I've written some pre-receive hook that denies pushed commits which have author's date earlier then current branch HEAD. It's done to prevent not triggering automated builds which are based on authors' timestamps.

But some time later I had to rollback branch to previous state. It is not convenient way to "git update-ref ..." on the server, I'd like to git push --force, but there is a question in the first sentence:

How to know in pre-receive hook that commit has been pushed with --force option?

Thanx in advance

Re: pre-receive/update hook: how to know forced push?

After some investigation of sources it seems to me decision to push changes to server or not is made by git client, so server can only reject pushed updates.

Some examples of necessary detections can be found in 'contrib/hooks/post-receive-email' hook.

Sorry for the noise
