Module ‐ Patch - camptocamp/github-app-geo-project GitHub Wiki

When a workflow failed, see if there is an attached artifact with a name that ends with .patch, and try to apply it on the branch, in a new commit.

This module automates the process of applying patch files generated by CI workflows. When a workflow fails and produces a .patch artifact, the module will:

• Download the .patch artifact from the failed workflow run.
• Attempt to apply the patch to the current branch.
• Commit the changes with a message based on the patch filename or a default message.
• Push the commit to the pull request branch, allowing the workflow to re-run with the proposed fix.

This helps contributors and maintainers quickly test and apply automated fixes suggested by CI jobs.

• Ensure the workflow produces a valid .patch file as an artifact on failure.
• The module will only attempt to apply patches if the artifact is present and can be cleanly applied.
• Review the resulting commit to ensure the patch does not introduce unintended changes.
