Arseniy Alekseyev <aalekseyev@janestreet.com> [Mon, 10 Oct 2022 14:48:39 +0100] rev 49520
dirstate-v2: skip evaluation of hgignore regex on cached directories By making the computation of [has_ignored_ancestor] lazy we're eliding its computation in the common case when none of its descendants have changed on disk. On a ~400k files repo, with a cached status, we saw a ~64% reduction in CPU time, resulting in a speedup of ~10-15% (on ZFS), and a speedup of ~38% of XFS (XFS has faster stat operations for some reason).

Craig Ozancin <c.ozancin@gmail.com> [Fri, 30 Sep 2022 09:05:48 -0600] rev 49519
releasenotes: use re.MULTILINE mode when checking admonitions Release note admonitions must start at the beginning of a line within the changeset description: .. admonitions:: The checkadmonitions function search for and validates admonitions. Unfortunately, since the ctx.description is multi-line, the regex search always fails unless the admonition is on the first line. This changeset adds re.MULTILINE to the re.compile to make the re opbject multi-line.

Matt Harbison <matt_harbison@yahoo.com> [Mon, 10 Oct 2022 11:28:19 -0400] rev 49518
windows: gracefully handle when the username cannot be determined This assumes implementation details, but I don't see any other way than to check the environment variables ourselves (which would miss out on any future enhancements that Python may make). This was originally reported as https://foss.heptapod.net/mercurial/tortoisehg/thg/-/issues/5835.

Arseniy Alekseyev <aalekseyev@janestreet.com> [Wed, 05 Oct 2022 15:45:05 -0400] rev 49517
rhg: parallellize computation of [unsure_is_modified] [unsure_is_modified] is called for every file for which we can't determine its status based on its size and mtime alone. In particular, this happens if the mtime of the file changes without its contents changing. Parallellizing this improves performance significantly when we have many of these files. Here's an example run (on a repo with ~400k files after dropping FS caches) ``` before: real 0m53.901s user 0m27.806s sys 0m31.325s after: real 0m32.017s user 0m34.277s sys 1m26.250s ``` Another example run (a different FS): ``` before: real 3m28.479s user 0m31.800s sys 0m25.324s after: real 0m29.751s user 0m41.814s sys 1m15.387s ```

rhg: enable in case ui.statuscopies=True rhg already has code to support ui.statuscopies, but it's disabled, for seemingly no good reason.
