New and Noteworthy 4.1

JGit

Basic Support for Push Certificates

• Push certificates are used to verify the pusher's identity when a git server receives a signed pack
• Parsing of push certificates
• Storage of push certificates, they are stored in a special ref "refs/meta/push-certs". The filenames in the tree are ref names followed by the special suffix "cert", and the contents are the latest push cert affecting that ref.
• Configuration for server-side signed push verification
• Support for push certificates in BaseReceivePack and RefUpdate

Ignore Handling

• Allow leading/trailing spaces in ignore rules
• Allow leading literal '#' and '!' in ignore rules if they are escaped
• Don't trim trailing space if it is escaped with backslash

Other Enhancements

• Add setTargetBranch in RepoCommand.
• Add API to remove repositories from RepositoryCache
• Add new submodule layout to SubmoduleAddCommand
• Handle stale NFS file handles on packed-refs file
• Add a grace period for packfiles during GC so that they are retained during GC until configured expiration age is reached

Performance Improvements

• Use java.io.File instead of NIO to check existence of loose objects in ObjectDirectory to speed up inserting of loose objects
• Reduce memory consumption when creating bitmaps during writing pack files

Build and Release Engineering

• Enable annotation based NPE analysis in jgit
• Update Jetty to 9.2.13.v20150730
