tests: show that `hg cp -A --at-rev .` doesn't work for renames I clearly forgot to implement (and test) support for marking of renames when I added support for marking of copies :( Differential Revision: https://phab.mercurial-scm.org/D8493

rust-matchers: add TODO about incomplete `Display` for `IncludeMatcher` This is purely for future reference, I don't think this is a problem right now, since the `Display` is *only* used to ease debugging and has no real users. Differential Revision: https://phab.mercurial-scm.org/D8492

rust-filepatterns: match exact `rootglob`s with a `HashSet`, not in the regex This optimization yields some very interesting results in `rootglob`-heavy repositories. I build a test repository of the following structure: ``` root /<uuid>/build/empty_file ... repeat for 4000 entries ``` and a `.hgignore` containing the corresponding 4000 `rootglob` entries pointing to all `build/` folders. Rust+c `hg status` goes from 350ms down to 110ms. Differential Revision: https://phab.mercurial-scm.org/D8491

dirstate: force _checkexec to return a bool posix.checkexec can return True, False, or None. The rust status implementation expects a boolean, so make sure _checkexec returns a boolean. Differential Revision: https://phab.mercurial-scm.org/D8432

locking: wait for locks in `hg cp` and `hg mv` I traced this back to revision 1822 (64df422), and there's no explanation why we would prefer to error out instead of waiting for the locks. Differential Revision: https://phab.mercurial-scm.org/D8464

nodemap: teach `hg debugformat` about the persistent nodemap option We have a new requirement, we should display it. Differential Revision: https://phab.mercurial-scm.org/D8430
