feat: add check_uncommitted configuration flag #1613

PreistlyPython · 2025-09-17T03:49:17Z

Description

This PR implements a new configuration flag check_uncommitted to prevent version bumping when there are uncommitted changes in the working tree, addressing issue #1194.

Changes Made

Configuration: Added check_uncommitted flag to settings with default value False for backward compatibility
CLI Integration: Added --check-uncommitted and --no-check-uncommitted flags to cz bump command
Error Handling: New UncommittedChangesError exception with exit code 33
Git Integration: Added has_uncommitted_changes() function that properly detects modified, added, or deleted files while ignoring untracked files
Comprehensive Testing: Full test coverage for all functionality

Key Features

Backward Compatible: Feature disabled by default, no breaking changes
CLI Override: Command-line flags can override configuration settings
Smart Detection: Detects uncommitted staged and unstaged changes, ignores untracked files
Clear Error Messages: Helpful error message with guidance on resolution
Proper Integration: Seamlessly integrated into existing bump workflow

Implementation Details

The feature works by checking for uncommitted changes before creating the version bump commit. When enabled, it prevents accidentally including uncommitted work in release commits, which is especially important in automated workflows.

Code Changes

Add test cases to all the changes you introduce
Manually test the changes:
- Verify the feature/bug fix works as expected in real-world scenarios
- Test edge cases and error conditions
- Ensure backward compatibility is maintained
- Document any manual testing steps performed
Update the documentation for the changes

Expected Behavior

When check_uncommitted is enabled (either via configuration or CLI flag), cz bump will:

Check for uncommitted changes before creating the bump commit
If uncommitted changes are found, abort with a clear error message and exit code 33
If no uncommitted changes exist, proceed with normal bump behavior
CLI flags (--check-uncommitted/--no-check-uncommitted) override configuration settings

Steps to Test This Pull Request

Set up a test repository with commitizen
Make some uncommitted changes (modify a tracked file)
Test without flag: cz bump (should include uncommitted changes - existing behavior)
Test with flag: cz bump --check-uncommitted (should abort with error)
Commit changes and retry: cz bump --check-uncommitted (should succeed)
Test configuration: Add check_uncommitted = true to config and verify behavior
Test override: Use --no-check-uncommitted to override config setting

Additional Context

Fixes #1194

This implementation provides the requested functionality to prevent unexpected uncommitted changes from being included in version bump commits, similar to bump-my-version's allow_dirty feature but with inverted logic for better default behavior.

The feature is designed to be especially useful in CI/CD pipelines where accidental inclusion of uncommitted changes could lead to inconsistent releases.

Please refer to our existing unit tests and follow the pattern.

Is this some leftover generated by your agent? It didn't clean up these properly.

Some questions for the implementation:

What is the difference between "--check-uncommited is True" and "--no-check-uncommited is False"?

Can't we implement this feature with only 1 config flag?

+        if check_uncommitted is None:
+            check_uncommitted = self.config.settings.get("check_uncommitted", False)


nit:

You could simply rewrite it as the following

check_uncommitted = self.arguments.get("check_uncommitted", self.config.settings.get("check_uncommitted"))

You didn't add no_check_uncommitted here though. The inconsistency needs to be resolved.
