Eclipse JGit: Java implementation of Git 5.9.0

Features

• Add DfsBundleWriter which writes out the entire repository to a Git bundle file. Useful for backing up a repository as-is.
• 565774 DirCache: support git index V4
• Add support for tree filters when fetching

Performance Improvements:

• 565707 FS: use binary search to determine filesystem timestamp resolution
• Do not send empty blob in response to blob:none filter. In particular, this means we do not need to look up the size of the filtered blobs, which should speed up clones.
• PackBitmapIndex: Do not buffer inflated bitmap during bitmap creation.

Bug Fixes

• 565854 SshdSession: close channel gracefully
• 564386 GPG: include signer's user ID in the signature
• ResolveMerger: do not content-merge gitlinks on del/mod conflicts
• ResolveMerger: choose OURS on gitlink when option ignoreConflicts is used. GITLINK merging is a special case of recursive merge because of limitations of GITLINK type of entry. It can't contain more than 1 sha-1 so jgit can't write merge conflicts in place like it can with a blob.
• Fix possible NegativeArraySizeException in PackIndexV1
• 565637 Do not prematurely create directory of jgit's XDG config file
• 566170 FS: write to JGit config in a background thread
• 566170 FS: don't cache fallback for timestamp resolution if running in background
• 565048 Keep line endings for text files committed with CR/LF on text=auto
• 563740 Delay WindowCache statistics JMX MBean registration
• Fix JSchProcess.waitFor() with time-out
• 565394 sshd: work around a race condition in Apache MINA sshd 2.4.0/2.5.x
• 563380 sshd: store per-session data on the sshd session object
• 564372 FS_POSIX: avoid prompt to install the XCode tools on OS X
• 564202 Use LinkedBlockingQueue for executor determining filesystem attributes
• 565081 DiffFormatter: correctly deal with tracked files in ignored folders
• 564428 Fix writing GPG signatures with trailing newline
• Improve error message when receive.maxCommandBytes is exceeded
• LfsConnectionFactory#getLfsUrl: Fix unconditional break in for-loop
• MergedReftable: Include the last reftable in determining minUpdateIndex
