followlines: don't put Unicode directly into the .js file (issue6559) Apparently some web server setups may serve this file in a different encoding than UTF-8, and that results in visual garbage in the followlines button that renders for every line in a file. So instead of using this Unicode character in UTF-8 we can encode it as \u2212. Or, to be more explicit, we can use − HTML entity, which resolves into exactly that character. Since now we're using innerHTML property to set the minus part of the button, let's use it to set the plus part as well (even though the plus sign was plain ASCII). A wise man once said "A foolish consistency is the hobgob... eh, whatever." Throw a brick at me if this makes things worse. Differential Revision: https://phab.mercurial-scm.org/D12597

wix: bump the minimum Windows required to 8.1 PyOxidizer binaries are built with py 3.9.6, so not even Windows 7 is supported. Unfortunately, there don't appear to be more recent values for newer versions of Windows, but at least Windows 8.1 is still in extended support for another 9 months or so.

filemerge: add configs to disable some or all partial merge tools When rolling out partial merge tools to users, it's useful to be able to easily turn one or all of them off if a problem is discovered. This patch adds support for that. They can of course also be useful for individual users to be able to temporarily turn off a tool they are otherwise using.

branching: merge stable into default

Added signature for changeset 0ddd5e1f5f67

Added tag 6.1.2 for changeset 0ddd5e1f5f67

ci: remove py2-rust support Nobody cares about this very narrow usecase, and py2 support is over by July 1st. This helps with the CI load, and removes some flakiness.

relnotes: add release notes for 6.1.2

docs: use proper rst markup for preformatted blocks The multiple lines were re-flowed to a single line, both in man page and html.

test-dirstate: print something when the check is skipped This makes a programming error obvious in cases when it should not be skipped Differential Revision: https://phab.mercurial-scm.org/D12602

test-dirstate: fix detection of Rust environment variable The Rust path never actually worked. This change also improves clarity of the comment. The next change will ensure we print something when this check fails. Differential Revision: https://phab.mercurial-scm.org/D12601

rust-dirstate-v2: fix the unused bytes counter when rewriting the dirstate As per the previous patch, the counter was incorrectly carried over from the old docket when it should be reset for a complete rewrite. Differential Revision: https://phab.mercurial-scm.org/D12594

rust-dirstate-v2: show `unused_bytes` counter is not reset on total rewrite This was picked up by @aalekseyev when doing unrelated debugging. The Rust implementation was never resetting this counter, so a brand new file would carry over the old counter. As I write this, my counter is a supposed 7389089 unused bytes for a total of 170978 bytes in the data file. Feel free to post your own high score.

test-dirstate: use new `--docket` flag to get the data uuid This is more robust. Differential Revision: https://phab.mercurial-scm.org/D12592

debugcommands: remove `debugdirstateignorepatternhash` This is replaced by the more complete `--docket` option to `debugstate`. Differential Revision: https://phab.mercurial-scm.org/D12591

dirstate-v2: add flag to `debugstate` to print docket information This is useful information that we don't easily have access to currently, unless you speak fluent xxd. This replaces `debugdirstateignorepatternshash`, which I'll remove in the next changeset. Differential Revision: https://phab.mercurial-scm.org/D12590

doc: use an absolute path in sys.path to work around a python DLL loading bug This bug[1] was causing the zstd entry under "Available Compression Engines" to be omitted from the documentation for some versions of python3. I could upgrade, but past upgrades have broken venvs and clobbered installed packages. It's a trivial workaround, so there's no sense in leaving this subtle issue. It was flushed out by changing the module policy here from 'allow' to 'c', and seeing this error: ImportError: DLL load failed while importing parsers: The parameter is incorrect.

rhg: fix dirstate-v2 data file removal system In D12581 I introduced logic to remove the previous dirstate-v2 data file after a new one is created (and its corresponding docket), but the logic was flawed. I fixed it and made it simpler to understand by gather all logic in a single expression. Differential Revision: https://phab.mercurial-scm.org/D12586

rhg: use `Command::exec` instead of `Command::status` `rhg` is supposed to be a transparent executable, using a subprocess defeats that purpose. See inline comments for more details. This also introduces the `which` crate to check if the fallback executable actually exists to help debugging (plain `execve` doesn't give much information). The error code 253 is used to signify that the fallback is not found, but may mean in the future that it is otherwise invalid if we start being more specific.

commit: don't use hard-coded `.hg/last-message.txt` path in error message Whoever wrote D8463 just used a hard-coded path to `.hg/last-message.text` instead of using the relative path that was already available in the `msgfn` variable (and used just a few lines up in related message). Let's fix that. Differential Revision: https://phab.mercurial-scm.org/D12585
