Eclipse JGit: Java implementation of Git 6.8.0

Features

• Improve parsing of commit message trailers to allow multiline trailers
• BitmapIndex: Add interface to track bitmaps found (or not) for monitoring
• CommitGraphWriter: Add progress monitor to bloom filter computation during gc
• CommitGraphWriter: Unnest reporting of generation-number progress
• 582292 Add support for git config option repack.packKeptObjects
• Use ShutdownHook to gracefully handle JVM shutdown in all classes which already registered their own shutdown hook
• 582379 Add ShutdownHook to cleanup FileLocks on graceful JVM shutdown to avoid stale lock files if the JVM is terminated gracefully.
• Unregister ShutdownHook when GC#PidLock is closed
• 342790 RevertCommand: support for inserting a Gerrit change ID

Performance Improvements

• 578550 Optimize RefDirectory.getRefsByPrefix(String...) by matching all ref prefixes in one pass over all refs.
• UploadPack: use want-refs as advertised set in fetch v2. Treat wanted-refs like a ref-prefix when calculating the advertised refs on v2 fetch command. Less refs means a faster setup and less walk for the reachability checks.

Bug Fixes

• 582538 Fix branch ref existence check. When a tag with the same name as the branch exists, branch creation should work too.
• BasePackFetchConnection: Avoid full clone with useNegotiationTip
• 451508 FileBasedConfig: in-process synchronization for load() and save() to prevent deleting content of the config on Windows.
• 451508 FileUtils.rename(): better retry handling when atomic move fails on Windows
• 451508 FileBasedConfig: ensure correct snapshot if no config file exists
• 451508 DeleteBranchCommand: update config only at the end if multiple branches are deleted
• 582526 RebaseCommand: return correct status on stash apply conflicts. Ensure that also the fast-forward cases return status STASH_APPLY_CONFLICTS when applying the stash produces conflicts.
• 582292, 582455 Do not exclude objects in locked packs from bitmap processing. Introduce the '--pack-kept-objects' option in GC for including the objects contained in the locked packfiles during the repack phase, to avoid accidental pruning during GC.
• 582394 OSGi: move plugin localization to subdirectory to avoid filename clashes in non-OSGi environment.
• DfsPackFile: Record index load event only in one place
