setup: use the full executable manifest from `python.exe` The manifest embedded by the build process (before the string here is added) already accounts for the `<requestedExecutionLevel level="asInvoker" ...>` setting. (Note that the PyOxidizer build is missing this, so it will likely trigger the UAC escalation prompt on each run.) However, using `mt.exe` to merge the fragment with what is already in the manifest seems to strip all whitespace, making it unreadable. Since Mercurial can be run via `python.exe`, it makes sense that we would have the same manifest settings (like the supported OS list), though I'm unaware of any functionality this enables. It also has the nice effect of making the content readable from a resource editor. The manifest comes from python 3.9.12. Note that this seems to strip the `<?xml ... ?>` declaration when viewed with ResourceHacker 5.1.7, but this was also the state of things with the previous commit, and `mt.exe "-inputresource:hg.exe;#1" -out:extracted` does contain the declaration and the BOM in both cases. No idea why this differs from other executables.

setup: unconditionally enable the `long-paths-support` option on Windows I don't see anything talking about why this was experimental in the first place, but maybe it was concern about the level of python2 support for it. But now, both `python.exe` and the PyOxidizer build of `hg.exe` have a manifest that enables it, so leaving it off would mean some Mercurial installations could operate on a repo with long paths, and others couldn't. Note that only the wide character functions (XxxW) will have the length restriction lifted. Sadly, distutils applies `/MANIFEST:EMBED` to the linker in a way that can't easily be turned off, so we can't use `/MANIFESTFILE` with `extra_preargs` on `link_executable`. Fortunately, the compiler object provides a path to the `mt.exe` it found during initialization, because the previous incarnation seems to have assumed it is being run within an activated Visual Studio environment. That causes MSYS builds to fail, and probably would have broke the CI environment.

setup: stop shadowing the builtin `dir` symbol I hit this when debugging what's available on the compiler.

mergestate: action name was str Apparently the standard for them is still to use byte strings. Found while looking at something else

subrepo: avoid opening console window for non-native subrepos on Windows Prevent annoying command prompt windows popping up when using TortoiseHG with Git and SVN subrepos by passing creationflags=subprocess.CREATE_NO_WINDOW to subprocess.Popen.

ci: bump pytype to 2022.03.29 This is as far as we can go without running into issues with the vendored `attr` package. I tried updating that to the latest, and not only did it not fix the issue, but test-util.py failed due to some poking at `attr` internals that apparently is no longer valid. The `libcst` package is now pinned to what I have locally because trying to install the latest (0.4.7) complains that it can't find the Rust compiler. We should probably use a requirements file instead (and/or figure out why it can't find the Rust compiler), but I don't feel like dealing with another side quest.

typing: suppress a few attribute errors in url.py These are newly detected by pytype 2022.03.21. Not sure what is going on here- `realhostport` and `headers` are added outside of the constructor, so that makes sense. But PyCharm also thinks the private methods don't exist, though when clicking through the class hierarchy, it shows in the py3.9 source code.

typing: suppress a few pyi-errors with more recent pytype Not sure what's going on here, but these were flagged with pytype 2022.03.21. We can't update to something much more recent, because newer versions complain about various `attr` uses.

procutil: make stream detection in make_line_buffered more correct and strict In make_line_buffered(), we don’t want to wrap the stream if we know that lines get flushed to the underlying raw stream already. Previously, the heuristic was too optimistic. It assumed that any stream which is not an instance of io.BufferedIOBase doesn’t need wrapping. However, there are buffered streams that aren’t instances of io.BufferedIOBase, like Mercurial’s own winstdout. The new logic is different in two ways: First, only for the check, if unwraps any combination of WriteAllWrapper and winstdout. Second, it skips wrapping the stream only if it is an instance of io.RawIOBase (or already wrapped). If it is an instance of io.BufferedIOBase, it gets wrapped. In any other case, the function raises an exception. This ensures that, if an unknown stream is passed or we add another wrapper in the future, we don’t wrap the stream if it’s already line buffered or not wrap the stream if it’s not line buffered. In fact, this was already helpful during development of this change. Without it, I possibly would have forgot that WriteAllWrapper needs to be ignored for the check, leading to unnecessary wrapping if stdout is unbuffered. The alternative would have been to always wrap unknown streams. However, I don’t think that anyone would benefit from being less strict. We can expect streams from the standard library to be subclassing either io.RawIOBase or io.BufferedIOBase, so running Mercurial in the standard way should not regress by this change. Py2exe might replace sys.stdout and sys.stderr, but that currently breaks Mercurial anyway and also these streams don’t claim to be interactive, so this function is not called for them.

repo-upgrade: avoid a crash when multiple optimisation are specified In Python 3, the type are no longer comparable and this expose the error.

rust: remove excessive calls to `#[timed]` This makes trace output *really* noisy and is only useful in case you want to take a look at a single revlog. This is easy to add back on a case-by-case basis and does not need to stay with the more permanent timers.

rhg: add error message for paths outside the repository when cwd != root This mirrors the Python implementation. The relative path handling should probably be refactored into a util, but it it out of scope for this change.

rust: don't swallow valuable error information This helps when diagnosing corruption, and is in general good practice. The information is here, valuable and can be used easily.

rust: add message to `DirstateV2ParseError` to give some context This is useful when debugging.

py3: stop using deprecated Element.getchildren() method in convert/darcs This has been deprecated since py3.2, and removed entirely in py3.9

py3: fix bytes/unicode issues in convert/darcs - don't check for a binary symbol in globals(), which meant it always thought the module wasn't available - don't pass bytes to stdlib methods - return bytes in getchanges where Mercurial expects to see them

convert: remove old ElementTree import cruft from darcs All the `import elementtree` attempts seem to pre-date py2.5, when it was brought into the standard library, and the manual `cElementTree` fast implementation import has been unnecessary and deprecated since py3.3.
