  • mto: This revision was merged to the branch mainline in revision 2274.
  • Revision ID: robertc@robertcollins.net-20070206023342-hv5o5qh6pdktiwbc
New branch hooks: post_push, post_pull, post_commit, post_uncommit. These
complement the set_rh hook by allowing different actions, and awareness of
the prior state of the branch, for operations where this matters.

Fix the inability to do a bzr pull --overwrite of a heavyweight checkout.

Add branch implementation tests for uncommit and commit.

(Robert Collins)
