Mercurial pretxncommit hook - act only on commit, ignore rebase and patch

Question

We are using pretxncommit hook for HG to run a quick static analysis check on code commited. However the hook is triggered on applying any changes to commit tree - which includes rebasing and using MQ to edit and squash commits.

Is it possible to somehow check what type of change is happening in hook itself? Like

def analyze_hook(ui, repo, node=None, **kwargs):
    if repo.state.is_commit_added and not (repo.state.is_rebase or repo.state.is_patch):
        return 0

It is possible to from mercurial.cmdutil import _getrepostate and check _getrepostate(repo) is not None to check if the repo is currently in process of rebase or graft. It prevents hook from acting on merge conflicts, but it still acts once rebase or graft or MQ move is finished. – Borneol

Answer 1

you'd want to check the HG_SOURCE to see what operation is bringing you those commits

e.g. https://github.com/vmg/hg-stable/blob/master/tests/test-hook.t
