Performance Improvements

  • Improve performance of DirCacheBuilder
  • Speed-up creation of DirCacheEntry
  • Speed-up garbage collection by improving generation of bitmap index
  • Speed-up delta-packing
  • Improve bitmap index calculation to speed-up reachability calculations done during transport

Release Engineering and Build

  • Use japicmp [2] instead of clirr to detect API changes since clirr doesn't support Java 8
  • Use @Nullable annotations to aid detection of NPEs at design time
  • Alternative buck build [3], much faster than Maven, can't build OSGi artefacts yet
