Original Pull Request: https://github.com/git-ai-project/git-ai/pull/270

State: closed
Merged: Yes

Unrelated to imara_diff migration, but I caught it while working on the migration. Git AI was not properly changing line attribution in the case where a pure deletion was made on a single line, for ex changing a line from Hello world to just Hello would leave the original attribution. The root cause of this bug is that the new attribution for the deletion wasn't being saved, because it had no length. Added a new 'tombstone' attribution and tests to make sure Git AI properly attributes such changes in checkpoints.
