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.

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.

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

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not only did it not fix the issue, but test-util.py failed due to some poking at `attr` internals that apparently is no longer valid.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.
