This fixes an issue where GitUp wrote incorrect data to the index, causing both the Git CLI and GitUp itself to produce incorrect diffs.
Reproducing
Red Graphite.theme
has changes, and is fully staged. In it, unstage the remove/add deltas at line 9.Fix
For performance, when producing diffs, Git skips reading the contents of files under some conditions. Here, the bug is that Git skips reading our file because it assumes it's identical between the working directory and the stage. Setting the file's date to null in the index prevents that behavior.
Notes
This fix has been in use in Retcon since January 2024, with no noticed adverse effect.
