Files previously tracked in the snapshot that were later added to .gitignore
were still being included in patches. This happened because:
1. diff-files returns tracked files regardless of gitignore status
2. git add was re-adding all files including those now ignored
3. patch() and diffFull() output wasn't filtering out gitignored files
The fix:
- In add(): Use git check-ignore --no-index to identify newly-ignored files
(even if they're tracked in source git) and remove them from the snapshot
index with git rm --cached
- In patch(): Filter out gitignored files from the diff output using
git check-ignore --no-index
- In diffFull(): Filter out gitignored files from the diff output
Tests added:
1. files tracked in snapshot but now gitignored are filtered out
Uses a.txt (from bootstrap) to test files already in git
2. gitignore updated between track calls filters from diff
Tests that gitignore changes between two track() calls
properly filter from diffFull results
Fixes issue where files like .android-sdk were re-added to snapshots
even after being added to .gitignore.
