rust-discovery: type alias for random generator seed It just makes our life easier Differential Revision: https://phab.mercurial-scm.org/D7715

tests: split out another ~1/2 of test-graft.t The tests involving renames were also quite independent from the rest. Differential Revision: https://phab.mercurial-scm.org/D7803

tests: split out ~1/3 of test-graft.t test-graft.t is ~2400 lines and takes 34s to run. This patch moves the last ~1/3 of it to a separate file. The parts now run in 22s + 13s. On top of that, we can remove the #testcases from the old file, so it's only 22s + 2*13s instead of the 2*34s it was before. Differential Revision: https://phab.mercurial-scm.org/D7802

overlwayworkingctx: remove doubly bad reference to wrapped ctx for copies `_wrappedctx` lives on overlwayworkingctx, not on the repo object, so we should access it as `._wrappedctx`, not `._repo._wrappedctx`. More importantly, the overlayworkingctx is relative to its base, not including it, so the copies returned should not include copies made in the base.

movedirstate: get copies from dirstate before setting parents Setting dirstate parents can modify the copies recorded in the dirstate when there are two dirstate parents. I don't think we ever call movedirstate() when there is more than one parent, but it seems clearer to get the copies from the dirstate first anyway.

fix: convert clang-format-ignorelist to use wildcards It's very brittle to specify the exact filenames for these vendored/thirdparty libraries; when there's an upgrade, it's likely not going to be updated. Differential Revision: https://phab.mercurial-scm.org/D7619
