strip: incrementally update the branchheads cache after a strip This function augments strip to incrementally update the branchheads cache rather than recompute it from scratch. This speeds up the performance of strip and rebase on repos with long history. The performance optimization only happens if the revisions stripped are all on the same branch and the parents of the stripped revisions are also on that same branch. This adds a few test cases, particularly one that reproduces the extra heads that mpm observed.

      Corrupt an hg repo with two pulls.

      create one repo with a long history

        $ hg init source1

        $ cd source1

        $ touch foo

        $ hg add foo

        $ for i in 1 2 3 4 5 6 7 8 9 10; do

        >     echo $i >> foo

        >     hg ci -m $i

        > done

        $ cd ..

      create one repo with a shorter history

        $ hg clone -r 0 source1 source2

      create a third repo to pull both other repos into it

        $ hg init corrupted

        $ cd corrupted

      use a hook to make the second pull start while the first one is still running
