rust: fix signature of rustlazyancestors_init() function Obviously, sizeof(int) != mem::size_of::<usize>() on amd64, though the argument would be passed in 64-bit register anyway.

tests: require SQLite 3.8.3+ as sqlitestore relies on "WITH" clause The test fails on gcc112 because the SQLite is too old. https://sqlite.org/changes.html#version_3_8_3

relnotes: various tweaks for release notes Stop filtering out commits that are expected to be covered by releasenotes extension: now we want two lists, one for WhatsNew and one for ReleaseX.Y. Use `only(stoprev, startrev)` to make `relnotes -h` output be actually true about what revisions are included. More filter rules, mostly obvious. More classifying rules to have less things in "unsorted". Looks like nargs=1 was just making args.startrev and args.stoprev be lists for no reason. BC and API sections are renamed to what we're using on the WhatsNew page, and also just skipped if empty.

delta: skip "empty delta" optimisation for non-general case (issue6006) Non-general delta repository cannot delta against anything than prev. So even if the delta to prev is empty we should use it. This is similar to the change made in bafa1c4bb7a8. Differential Revision: https://phab.mercurial-scm.org/D5201

narrow: fix copies._fullcopytracing() narrowspec filtering in graft case I broke this too in 707c3804e607 (narrow: move copies overrides to core, 2018-09-28). Hopefully I'm done fixing things broken by that commit now. Differential Revision: https://phab.mercurial-scm.org/D5213

tests: demonstrate broken copies._fullcopytracing() Turns out copies._fullcopytracing() was also broken. Differential Revision: https://phab.mercurial-scm.org/D5212

narrow: make copies.pathcopies() filter with narrowspec again I broke this in 707c3804e607 (narrow: move copies overrides to core, 2018-09-28). Differential Revision: https://phab.mercurial-scm.org/D5203

tests: demonstrate broken copies.pathcopies() Differential Revision: https://phab.mercurial-scm.org/D5202

setup: explain to distutils how we write rc versions When we use a rc version number (e.g. 4.8rc0), bdist_msi is using distutils.StrictVersion to parse it into a tuple of numbers. By default, StrictVersion.version_re only recognizes [ab] for alpha/beta, where mercurial may use '-rc' or 'rc'. This change makes StrictVersion parse correctly our version numbers, so that bdist_msi doesn't fail on rc versions.

changegroup: restore default node ordering (issue6001) Changeset db5501d9 changed the default node ordering from "storage" to "linearize". While the new API is more explicit and cleaner, the "linearize" order is problematic on certain repositories like netbeans where it makes bundling slower the more nodes we bundle. Pushing and pulling 100 changesets was ~20% slower and pushing and pulling 1000 changesets was ~600% slower. A very quick analysis of profile traces showed that the pull operation was taking more time creating the delta. Putting back the old default order seems to be the safe option. With more time during the next cycle, we can understand better the impact of sorting with the DAG order by default, the source of the regression and how to mitigate it. /!\ We are still waiting for the full performance impact but with this patch, bundling and pulling locally (not on the performance workstation) 1000 changesets on the netbeans repository is as fast as before the regression.
