copies-rust: move is_ancestor caching within the rust code Now that the OrdMap merging is fast, smaller things start to matters. We move the caching of `is_ancestor` call within the Rust code. This avoid round-trip to Python and help us to shave more time on our slower case: Repo Cases Source-Rev Dest-Rev Old-Time New-Time Difference Factor ------------------------------------------------------------------------------------------------------------------------------------ pypy x0000_revs_x_added_0_copies d1defd0dc478 c9cb1334cc78 : 2.780174 s, 2.137894 s, -0.642280 s, × 0.7690 mozilla-try x0000_revs_xx000_added_x000_copies 89294cd501d9 7ccb2fc7ccb5 : 9.843481 s, 8.100385 s, -1.743096 s, × 0.8229 Note: I would happily have used native code for ancestors computation, however I failed (did not tried hard) to created a rust version that goes as fast as the current C version.
