Pierre-Yves David <pierre-yves.david@ens-lyon.org> [Fri, 04 Jan 2013 03:15:21 +0100] rev 18275
performance: speedup computation of unstable revisions
In their current state, revset calls can be very costly, as we test
predicates on the entire repository.
This change drops revset call in favor of direct testing of the
phase of changesets.
Performance test on my Mercurial checkout
- 19857 total changesets,
- 1584 obsolete changesets,
- 13310 obsolescence markers.

performance: speedup computation of mutable revisions
In their current state, revset calls can be very costly, as we test
predicates on the entire repository. The "mutable" filter is used
during branch cache loading operation. We need to make it fast.
This change drops revset calls in favor of direct testing of the
phase of a changeset.
