Matthias Sohn fde7a271a4 Ensure that GC#deleteOrphans respects pack lock If pack or index files are guarded by a pack lock (.keep file) deleteOrphans() should not touch the respective files protected by the lock file. Otherwise it may interfere with PackInserter concurrently inserting a new pack file and its index. The problem was caused by the following race. All mentioned files are located in "objects/pack/". File endings relevant in "pack" dir: .pack .keep .idx .bitmap When ReceivePack receives a pack file it executes the following steps: ReceivePack.service(): receivePackAndCheckConnectivity(): receivePack(): receive the pack parse the pack, returns packLock (.keep file) PackInserter.flush(): write tmpPck file: "insert_<random>.pack" write tmpIdx file: "insert_<random>.idx" real pack name: "pack-<SHA1>.pack" real index name: "pack-<SHA1>.idx" atomic rename tmpPack to realPack atomic rename tmpIdx to tmpIdx execute commands unlock pack by removing .keep file trigger auto gc if enabled When PackInserter.flush() renames the temporary pack to the final "pack-xxx.pack" file the temporary pack index file "insert_xxx.idx" has no matching .pack file with the same base name for a short interval. If deleteOrphans() ran during that interval it deduced the pack index file was orphaned. Subsequently the missing pack index caused MissingObjectExceptions since objects contained in the pack couldn't be looked up anymore.
