remotefilelog: move most functions in onetimeclientsetup() to top level This is how most extensions seem to do it. It makes sure we don't accidentally depend on the captured ui instance. Differential Revision: https://phab.mercurial-scm.org/D6333

tests: avoid the word "dirty" to mean "not a descendant of merge base" The term "dirty" is no longer used in the code since 57203e0210f8 (copies: calculate mergecopies() based on pathcopies(), 2019-04-11). Differential Revision: https://phab.mercurial-scm.org/D6373

releasenotes: add a file in which to record release notes I've just spent a few very boring hours going through the changelog for the 5.0 release (829 commits). We only had 5 commits that used the syntax that the release notes extension expects. This commit adds a file in which we can record important changes. The file should preferably be edited in the patch that makes the important change, but it can also be edited after (I think this is an important benefit compared to the release notes extension). I'm thinking that we can rename the file from "next" to "5.1" or something when it's time, and then we'd create a new "next" file on the default branch. I've used the syntax that we use on the our wiki in the template, but I don't care much that we use any valid syntax at all. The idea is mostly to record important changes when they happen. I expect that some copy editing will be needed at release time anyway. Differential Revision: https://phab.mercurial-scm.org/D6332

record: avoid modifying the matcher passed as a method parameter No problem observed, but I remember the previous pattern causing problems with largefiles and/or subrepos. This special matcher was added in 419ac63fe29c, so directly modifying the `fail` callback was probably an oversight in 44611ad4fbd9. Differential Revision: https://phab.mercurial-scm.org/D6371

sslutil: add support for SSLKEYLOGFILE to wrapsocket I recently learned of a Firefox/Chrome feature that allows wiresharking otherwise-TLS'd network connections. Gloriously, there's a pypi module that enables this same feature on Python, so let's add support for it to Mercurial in case we need to wireshark some HTTPs connections.

phabricator: add custom vcr matcher to match request bodies Currently when the phabricator extension's conduit output changes the tests don't notice since the default vcr matcher only matches on 'method' and 'uri', not the body. Add a custom matcher that checks the same params are in the body (ignoring ordering). vcr's in-built body matcher can't be used since it fails under py3 with a "UnicodeEncodeError" on the "€ in commit message" tests. The DREV ids have decreased since the recordings were generated against a different phabricator instance to avoid spamming mercurial-devel.

merge with stable

absorb: be more specific when erroring out on merge commit When you have a merge commit checked out and run `hg absorb`, it would tell you abort: no mutable changeset to change That makes it sound like the problem is public commits when isn't really. Let's be more specific in this case. There was already a test case that test this, so that now prints the new message. I added a new test case that shows the old message (when a public commit is checked out). Differential Revision: https://phab.mercurial-scm.org/D6354

remotefilelog: log when we're about to fetch files I'm debugging a slow client situation and knowing how many files are in the batch request would be a nice thing. Differential Revision: https://phab.mercurial-scm.org/D6353

revset: populate wdir() by its hash or revision number It belongs to the same category as the null hash/revision, and we do handle these virtual identifiers in id()/rev() predicates. Let's do that more consistently.
