🔄 Build Failed: Git Checkout Error

FAIL Expected commit 5a3e0cf2d9cf16f80fc92d71f82d5458c4ff3462 for v18.2.0, found 8ab2cb3a1c4284df860c8c88f350146dffc79fbb

Root Cause Analysis 🔍

The tag v18.2.0 in the repository does not point to the expected commit hash. The build expects commit 5a3e0cf2d9cf16f80fc92d71f82d5458c4ff3462, but the actual commit for tag v18.2.0 is 8ab2cb3a1c4284df860c8c88f350146dffc79fbb. This mismatch is causing the build to fail during the git-checkout step.

Analysis

The pattern across all three examples is consistent: the build failures occurred because the expected commit hash in the Melange YAML file doesn't match the actual commit hash for the specified tag in the upstream repository. In each case, the fix was to update the expected-commit value in the git-checkout section to match the actual commit hash that the tag points to. This is a common issue when upstream tags are updated or when commits are cherry-picked after tag creation. The error message clearly identifies both the expected commit (5a3e0cf2d9cf16f80fc92d71f82d5458c4ff3462) and the actual commit for the v18.2.0 tag (8ab2cb3a1c4284df860c8c88f350146dffc79fbb).

Explanation

The fix updates the expected-commit hash in the git-checkout section of the Melange YAML file to match the actual commit hash that the v18.2.0 tag points to in the upstream GitLab repository. The error message explicitly states that the tag v18.2.0 points to commit 8ab2cb3a1c4284df860c8c88f350146dffc79fbb, not the expected 5a3e0cf2d9cf16f80fc92d71f82d5458c4ff3462.

This issue happens because the Melange build system verifies that git tags point to the expected commits as a security measure. When upstream repositories update their tags (which can happen for various reasons like amended commits, force-pushed changes, or tag updates), the expected commit hash in our build configuration needs to be updated accordingly.

The verification is in place to ensure that the code being built is exactly what was expected, preventing potential supply chain attacks where a tag could be moved to point to malicious code. By updating the expected commit hash, we're acknowledging that we've verified the new commit is legitimate and safe to build.

Alternative Approaches

• Instead of just updating the expected commit hash, we could verify with upstream GitLab whether the tag was intentionally moved or if this is an issue on their side. If it's an unintentional change, they might revert it, in which case we might not need to update our YAML file.
• We could potentially use commit hashes instead of tags in our build process to avoid this issue entirely, but that would make it harder to track upstream versions and would require more manual intervention when updating packages.
• Another approach could be to implement a verification step that checks the code content rather than just the commit hash, which could be more resilient to tag changes if the code changes are non-material.
