rust: hooking into Python code
We introduce a new class called 'rustlazyancestors'
in the ancestors module, which is used only if
parsers.rustlazyancestors does exist.
The implementation of __contains__ stays unchanged,
but is now backed by the Rust iterator. It would
probably be a good candidate for further development,
though, as it is mostly looping, and duplicates the
'seen' set.
The Rust code could be further optimized, however it already
gives rise to performance improvements:
median timing from hg perfancestors:
- on pypy:
before: 0.077566s
after: 0.016676s -79%
- on mozilla central:
before: 0.190037s
after: 0.082225s -58%
- on a private repository (about one million revisions):
before: 0.567085s

- on another private repository (about 400 000 revisions):

==================================== Testing head checking code: Case A-7 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category A: simple case involving a branch being superceeded by another. TestCase 7: multi-changeset branch, split on multiple other, (head on its own branch), same number of head .. old-state: .. .. * 2 branch (1-changeset, and 2-changesets) .. .. new-state: .. .. * 1 new branch superceeding the head of the old-2-changesets-branch, .. * 1 new changesets on the old-1-changeset-branch superceeding the base of the other .. .. expected-result: .. .. * push allowed .. .. graph-summary: .. ..
