Features
Reftable
- Implement FileReftableDatabase
Reftable is a binary, block-based storage format for the ref-database. It provides several advantages over the traditional packed + loose refs storage
Storage format:- O(1) write performance, even for deletions and transactions.
- atomic updates to the ref database.
- O(log N) lookup and prefix scans
- free from restrictions imposed by the file system: it is case-sensitive even on case-insensitive file systems, and has no inherent limitations for directory/file conflicts
- prefix compression reduces space usage for repetitive ref names, such as gerrit's refs/changes/xx/xxxxx format.
- FileReftableDatabase is based on FileReftableStack, which does compactions inline. This is simple, and has good median performance, but every so often it will rewrite the entire ref database.
- Add FileRepository#convertToReftable so existing testdata can be reused.
- pgm: add write stats to BenchmarkReftable
- pgm: add command to convert repo to reftable
- reftable: enforce ascending order in sortAndWriteRefs
- Documentation/technical/reftable: document rename in reflog
- Introduce RefDatabase#hasFastTipsWithSha1
