precommit hg hook wont run when commiting in sourcetree

S2HC_johan

I have a precommit hook that works fine when running hg commit in terminal. However when I commit in sourcretree, it seems it isn't executed.

How could I debug why the hook wont fire, or isn't it supported?

the config looks like:

[hooks]

precommit=python:my_python_hooks.hghooks.precommit

Hmm, we don't specifically turn off any hooks, but does your hook rely on any extensions? For safety, SourceTree disables custom extensions when running to avoid any unexpected behaviour, but you can turn them on again in Preferences > Mercurial. Hooks though, we don't override, and the root ~/.hgrc is still in the configuration stack.

I have tride to add the core extentions and have tried with both emeded mecurial and system. but it dosen't seem to be fired. If i start a terminal from the app and run the same command as the one presented in the commit window (hg commit -y -m "test"). Do you call via a shell or is it done directly through the python package? could it be something with my hook that needs a terminal?

Is there any way for me to get more output from sourcetree to try to debug?

SourceTree just calls 'hg' as a separate process, so except for it not being a full terminal it should behave the same way. You can see more of what's going on by going into Preferences and checking the box 'Always show full output', which will always display the full content of task windows (they normally auto-close on success and hide the detail).

Thank you for the quick response.

I have done some debugging in the python code and verified that the hook gets called.

What I'm curently focusing on is that the python code tries to make command line calls toards pylint and pep8 using subprocess.Popen(...) and mayby it's here things go south.
