graft-state: save --base in graft's state, fixing bug with graft --continue Without this change, running graft --continue after grafting a merge commit using --base (and encountering conflicts) will output "skipping ungraftable merge revision" even though we specified a base in the initial graft command. Graft's improve behaviour is reflected in test-graft.t. Differential Revision: https://phab.mercurial-scm.org/D8578

relnotes: advertize the possibility to use rust I think the rust work may have been mentioned in the release notes, but if so only in passing, and not as an invitation to try it out. I think the next version is a decent time to do this, because the rust doesn't come with performance regressions AFAIK, speeds up status noticeably when it applies, which is the case for most invocations of status, and doesn't have the undesirable restriction of regex around empty patterns anymore. I am cheating a bit, because I'm giving numbers for `hg status` in mozilla-central, but they have one hgignore pattern that uses lookaround, ".vscode/(?!extensions\.json|tasks\.json", which I took out as it would cause a fallback to python when unknown files are requested. But it seems that they could express their hgignore differently if they were so inclined. Not sure if there are limitation other than linux-only that I am not thinking of but would be worth mentioning upfront, to avoid disappointing users?

rust: add a pointer for profiling to the README As figuring out how to get useful profiles is not obvious. Differential Revision: https://phab.mercurial-scm.org/D8603

rust: update the mention of hgcli in rust/README.rst This may not be exactly right, but it's better than before. Differential Revision: https://phab.mercurial-scm.org/D8602

sslutil: fix comment to use inclusive or instead of exclusive or The incorrect "either" was introduced by one of my recent patches.

sslutil: propagate return value ssl.PROTOCOL_SSLv23 from protocolsettings() Also, protocolsettings() was renamed to commonssloptions() to reflect that only the options are returned.

sslutil: stop storing protocol and options for SSLContext in settings dict Call protocolsettings() where its return values are needed.

sslutil: rename 'minimumprotocolui' -> 'minimumprotocol' Before, both 'minimumprotocolui' and 'minimumprotocol' were used, but meaning the same.

sslutil: properly detect which TLS versions are supported by the ssl module For the record, I contacted the CPython developers to remark that unconditionally defining ssl.PROTOCOL_TLSv1_1 / ssl.PROTOCOL_TLSv1_2 is problematic: https://github.com/python/cpython/commit/6e8cda91d92da72800d891b2fc2073ecbc134d98#r39569316
