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. Before: ! unstable ! wall 0.017366 After this changes: ! unstable ! wall 0.008093 Performance test on a Mozilla central checkout: - 117293 total changesets, - 1 obsolete changeset, - 1 obsolescence marker.

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. Performance test on my Mercurial checkout - 19857 total changesets, - 1646 mutable revision Before: ! mutable ! wall 0.032405 After: ! mutable ! wall 0.001469 Performance test on a Mozilla central checkout: - 117293 total changesets, - 1 mutable changeset, Before: ! mutable ! wall 0.188636 After: ! mutable ! wall 0.000022

performance: speedup computation of unserved revisions In their current state, revset calls can be very costly, as we test predicates on the entire repository. The "unserved" filter is used in multiple applications, and in particular in some branch cache loading operations. We need to make it fast. This change drops revset calls in favor of direct testing of the phase of a changeset. Performance test on my Mercurial checkout - 19857 total changesets, - 1584 obsolete changesets, - 13310 obsolescence markers. Before: ! unserved ! wall 0.030477 After: ! unserved ! wall 0.011844 Performance test on a Mozilla central checkout: - 117293 total changesets, - 1 obsolete changeset, - 1 obsolescence marker.

performance: speedup computation of hidden revisions In their current state, revset calls can be very costlys, as we test predicates on the entire repository. The hidden filter is very widely used, and needs to be very fast. This change drops revset calls in favor of direct revision manipulation. Performance test on my Mercurial checkout - 19857 total changesets, - 1584 obsolete changesets, - 13310 obsolescence markers. Before: ! hidden ! wall 0.077553 After this changes: ! hidden ! wall 0.011230 Performance test on a Mozilla central checkout: - 117293 total changesets, - 1 obsolete changeset, - 1 obsolescence marker.

performance: speedup computation of obsolete revisions In their current state, revset calls can be very costly as we test predicates on the entire repository. As obsolete computation is used by the "hidden" filter, it needs to be very fast. This changet drops the revset call in favor of direct testing of the phase of a changeset. Performance test on my Mercurial checkout - 19857 total changesets, - 1584 obsolete changesets, - 13310 obsolescence markers.

clfilter: drop unnecessary explicit filtering on histedit Hidden changeset filtering is now done at repo level. The orphaned children computation will not include any (unless you add --hidden).
