Eclipse JGit: Java implementation of Git 5.10.0

Features

• Add constants for parsing git wire protocol version
• 514052 Add support for reading symrefs from pack capabilities
• 568038 Allow to resolve a conflict by checking out a file
• Implement git describe --all
• Override config http.userAgent from environment GIT_HTTP_USER_AGENT
• 541500 Support "http.userAgent" and "http.extraHeader" from the git config
• sshd: support the ProxyJump ssh config. This is useful to access git repositories behind a bastion server (jump host).

Monitoring & Logging

• Add new performance logging to register events of type duration. The proposed logging is similar to the performance logging in Gerrit: a global Singleton is collecting the performance logs in a thread-safe events list, and at the end of the monitored command the list of events is retrieved and written to a log, after which it is cleared.
• Measure time taken for reachability checks
• Measure time taken for negotiation in protocol V2
• 567309 Add TypedConfigGetter.getPath(). This enables EGit to override with a lenient variant that logs the problem and continues with the default value.
• ReceivePackStats: Add size and count of unnecessary pushed objects
• GC#deleteOrphans: log warning for deleted orphaned files

Bug fixes

• 569349 Fix PackInvalidException when fetch and repack run concurrently
• Gerrit 13544 Ensure that GC#deleteOrphans respects pack lock
• GC#deleteOrphans: handle failure to list files in pack directory
• Ensure GC.deleteOrphans() can delete read-only orphaned files on Windows
• 568950 PacketLineIn: ensure that END != DELIM
• Fix NPE in PerformanceLogContext
• Fix IOException occurring during gc
• Close Repository to fix tests failing on Windows
• 565776 Ensure .gitmodules is loaded when accessing submodule name
• sshd: better error report when user cancels authentication
• 566799 IndexDiffFilter: handle path prefixes correctly

Documentation
