exchangev2: avoid second look-up by node Accessing the revlog by node is slightly more expensive than by revision, so look up the revision first and use it afterwards. Differential Revision: https://phab.mercurial-scm.org/D9831

commit: look-up new revision once Look-up by node is slightly more expensive, so since it is necessary more than once, do it explicitly. Differential Revision: https://phab.mercurial-scm.org/D9830

resolve: also detect new :mergediff conflict markers The conflict markers created by `:mergediff` were not detected as conflicts, which affects both `commands.resolve.mark-check` and `mergetools.<tool>.check`. This patch fixes that. The new regex it uses for finding conflict markers is less restrictive because it `:mergediff` doesn't follow the `<<<<<<<` and `>>>>>>>` lines by a space (and a description). Hopefully lines like that don't give too many false positives. We can add back the space and make `:mergediff` add trailing spaces if it turns out to be a problem. OTOH, there will always be some false positives and we have ways of overriding the checks already. This patch can go onto the default or stable branch, depending on how much we care about an experimental feature. Differential Revision: https://phab.mercurial-scm.org/D9835

simplemerge: delete unused find_unconflicted() The function has been unused ever since it was introduced in 465b9ea02868 (Import 3-way merge code from bzr, 2007-04-16). Differential Revision: https://phab.mercurial-scm.org/D9832

perf: use the `perf--` prefix for perf command This is the one command namespace where they should not be any ambiguity about command that should be in it. The perf extensions is only adding performance related command. so this is a good ground to start putting dash folding to the tests. Differential Revision: https://phab.mercurial-scm.org/D9516

contrib: update PyOxidizer to 0.10.3 This is necessary to work around a bug that caused build failures on current stable with 0.9.0. This patch was used to build the 5.7rc0 Windows installers. Differential Revision: https://phab.mercurial-scm.org/D9858

contrib: stop building rust for every job This is just wasteful for all steps that do not use Rust. Differential Revision: https://phab.mercurial-scm.org/D9717

share-safe: fix an abort message that references the experimental requirement Differential Revision: https://phab.mercurial-scm.org/D9851

doc: drop the `exp-` prefix from the `share-safe` requirement I can't tell if we should leave the experimental one around for historical documentation purposes, but I'm not sure if there's value to doing that. Differential Revision: https://phab.mercurial-scm.org/D9849
