Container error `fatal: --local can only be used inside a git repository`

[Michele-Alberti]

Description
One of my workflows based on commitizen-action is now returning the following error:

It used to work properly and the yaml configuration file for the workflow was not subjected to changes when the issue occurred.

I have already tested that the error is raised for both commitizen-action@0.15.1 and commitizen-action@0.16.0.

The only step before commitizen-tools/commitizen-action@0.15.1 is actions/checkout@v3.

A similar issue is reported in peter-evans/create-pull-request#1170 and actions/checkout#760.

Docker image update
I've noticed that the image python:3.8 on DockerHub (used by the Dockerfile) was updated just before the first failure of the above-mentioned workflow.
According to the first reference, this issue may be related to Git version: a building process based on different images may explain why the workflow was successful and then failed in two consequent runs, with no configuration changes (and within a few hours of each other).

Having the exact same issue over here as well, first occurrence of the failure was earlier today (~4 hours ago).
No changed to the CI process were made on our end, which made me check this repo and seems like we weren't the only ones experiencing it.
Thanks for reporting @Michele-Alberti !
Would love to see a quick fix for this, since we heavily rely on this process for our CI/CD process. 🙏🏼 🥺

My pipelines also broke 😅 ideas on how to fix it are welcome! Gonna take a look at it

As @Michele-Alberti mentioned, the Python 3.8 image did change on 2023-02-04.

One thought is to fork the repository and pin the image to the previous digest from January.

I think this diff shows necessary digest.
I'm assuming that the action runs on Linux AMD64.

I will try this later today or tomorrow, but if someone else feels inspired, please go ahead.

My suspect is that it is a consequence of the recent update to DockerHub's python image.
Maybe a quick fix is possible with a simple change to the line FROM python:3.8 inside the Dockerfile.

It seems that the image for 3.8.15 was not changed in the last two months.

Another way could be to downgrade Git to a less recent version inside the Dockerfile. I have no idea about the old version though...

I was thinking of adding to the entrypoint.sh:

# Fix #56
git config --global --add safe.directory "/__w/commitizen-action/commitizen-action" || true
export GIT_CEILING_DIRECTORIES=/__w # for old git versions

Based on this.
Do you think it will work?

[jmuddle-via]

@woile that's worth a try, I think the git version in the container is older.

git version 2.30.2

PR is open #57

Tests are passing by using:

git config --global --add safe.directory "*"

[woile]

Seems to be working, the tests went ok, and this action was able to release itself.

On a plus, we now use alpine with py3.11, which should make things a bit faster, though I don't know how reliable is alpine this days, I hope better than a couple of years ago.

[Michele-Alberti]

I've updated commitizen-action to 0.16.1 and now it's working as expected.
Thank you @woile for finding and testing a solution.

I'm closing this issue.
