This repo contains a bunch of tools cooked up to fix firebase-js-sdk on May 24, 2019.

damage.txt contains the output of a git push --force that overwrite nearly all refs in the repository.

orig-commits.txt is extracted from damage.txt and contains all the original commit ids.

test.sh can be run against a repo to determine how many commits from the golden set are missing.

feiyangc@ had a copy with all the commits.

unpack.sh unpacks that copy and applies some fixes to it. See source.

cd firebase-js-sdk. The rest of the work was done from within the copy, where all commands are now in the parent directory.

../prune-locals.sh removes any local branches that shouldn't be published

../fix.py ../damage.txt fix fixes the refs based on contents of damage.txt

../fix.py ../damage.txt check verifies that the refs match with git rev-parse

Result was checked with git push --force --dry-run --tags origin 'refs/heads/*'.

The fix was a applied. Output in fixed.txt
