[JGIT PATCH 0/5] Fix major performance problems in UploadPack

If the client is really far ahead of the server, JGit's UploadPack can spend a massive amount of CPU time on the server just doing the same work over and over again. This series addresses the issue by taking advantage of cached data more frequently.

Shawn O. Pearce (5):
  Make RevTag getObject(), getName() final to prevent overrides
  Allow exceptions to be created with integer type codes
  Unify RevWalk parsing code to be more consistent across types
  Change RevObject dispose() semantics to avoid reparses
  UploadPack: Only recompute okToGiveUp() if bases changed
