setup: copy python3.dll next to hg.exe when building on Windows for hgext.git I thought I took care of this already, but it must have been that I just manually copied the file over locally when debugging why the pygit2 library wasn't loading. The problem with that is what was copied over was from py38, and then running a py39 build hard crashed when the extension was loaded. Differential Revision: https://phab.mercurial-scm.org/D10301

tests: stablize test-hook.t on Windows Apparently, hooks can't run `echo` directly, even from MSYS. Differential Revision: https://phab.mercurial-scm.org/D10300

tests: handle Windows file separator differences in test-config.t Differential Revision: https://phab.mercurial-scm.org/D10299

tests: update the detailed exit codes for icasefs gated tests The fact that there's already a detailed exit code after the last change here in test-casecollision-merge.t gives me some pause, but maybe it was found and changed manually? Differential Revision: https://phab.mercurial-scm.org/D10298

tests: update the detailed exit codes in test-phabricator.t I'm guessing this has slipped through because most people don't have the necessary `pytest-vcr` package installed. Differential Revision: https://phab.mercurial-scm.org/D10297

tests: avoid using rebaseskipobsolete=0 I'm about to delete the `rebaseskipobsolete` config. This patch updates a test to get hidden commits into the rebase state by using `hg debugobsolete` instead of setting `rebaseskipobsolete=0`. Differential Revision: https://phab.mercurial-scm.org/D10270

rebase: when using --keep, don't care about pruned commits or divergence `hg rebase --keep` creates duplicate commits (not successors), so I was surprised that it still skips pruned commits and errors out if it "would cause divergence" (it wouldn't). I guess this was just an oversight. We didn't have any tests for it, so I also included that. Differential Revision: https://phab.mercurial-scm.org/D10269

rebase: remove duplicate initialization of a field `obsolete_with_successor_in_destination` is already initialized in the constructor. Differential Revision: https://phab.mercurial-scm.org/D10268

rust: bump rust-cpython version to 0.5.2 we need a newer version to define "property" on Rust defined object. Differential Revision: https://phab.mercurial-scm.org/D10308

revlog: directly use the Struct object for related operation The Struct object has all the piece we needs, so no need to duplicate information on the revlog itself. Differential Revision: https://phab.mercurial-scm.org/D10307
