cleanup: remove pointless r-prefixes on single-quoted strings This is the promised second step on single-quoted strings. These had existed because our source transformer didn't turn r'' into b'', so we had tagged some strings as r-strings to get "native" strings on both Pythons. Now that the transformer is gone, we can dispense with this nonsense. Methodology: I ran hg locate 'set:added() or modified() or clean()' | egrep '.*\.py$' | xargs egrep --color=never -n -- \[\^b\]\[\^a-z\]r\'\[\^\'\\\\\]\*\'\[\^\'\ in an emacs grep-mode buffer, and then used a keyboard macro to iterate over the results and remove the r prefix as needed. # skip-blame removing unneeded r prefixes left over from Python 3 migration.

rust-threads: force Rayon to respect the worker count in config As per the inline comment, this is a workaround because Rust code does not yet know how to read config files. Differential Revision: https://phab.mercurial-scm.org/D7310

cleanup: remove pointless r-prefixes on double-quoted strings This is only double-quoted strings. I'll do single-quoted strings as a second step. These had existed because our source transformer didn't turn r"" into b"", so we had tagged some strings as r-strings to get "native" strings on both Pythons. Now that the transformer is gone, we can dispense with this nonsense. Methodology: I ran hg locate 'set:added() or modified() or clean()' | egrep '.*\.py$' | xargs egrep --color=never -n -- \[\^a-z\]r\"\[\^\"\\\\\]\*\"\[\^\"\] in an emacs grep-mode buffer, and then used a keyboard macro to iterate over the results and remove the r prefix as needed. # skip-blame removing unneeded r prefixes left over from Python 3 migration. Differential Revision: https://phab.mercurial-scm.org/D7305

formatting: remove another data-ogre from the config example The fix extension will pass the contents on stdin and read the output from stdout. By invoking `rustfmt` as `rustfmt {rootpath}`, we tell rustfmt to format the given path and update it on disk. That also makes rustftm not produce the formatted output to stdout. So the fix extension ends up writing out empty files. Differential Revision: https://phab.mercurial-scm.org/D7304

dagparser: suppress some pytype errors around pycompat.bytestring I can't justify why we're getting these errors, but nothing I do fixes these handful of calls, so let's just move on with suppressions. Differential Revision: https://phab.mercurial-scm.org/D7277

dirs: reject consecutive slashes in paths We shouldn't ever see those, and the fuzzer go really excited that if it gives us a 65k string with 55k slashes in it we use a lot of RAM. This is a better fix than what I tried in D7105. It was suggested by Yuya, and I verified it does in fact cause the fuzzer to not OOM. This is a revision of D7234, but with the missing set of an error added. I added a unit test of the dirs behavior because I needed to reason more carefully about the failure modes around consecutive slashes. Differential Revision: https://phab.mercurial-scm.org/D7252

repoview: define filteredchangelog as a top-level (non-local) class As suggested by Greg. This makes it easier for extensions to override the filtering. Differential Revision: https://phab.mercurial-scm.org/D7256

cmdutil: suppress bogus pytype errors pytype seems to handle our subclass of tuple (scmutil.status) especially poorly. We should probably file a bug. Differential Revision: https://phab.mercurial-scm.org/D7294

changegroup: suppress pytype error that's wrong Differential Revision: https://phab.mercurial-scm.org/D7293

changegroup: avoid shadowing a set with an int This confuses the heck out of pytype, and I basically agree with it that this shadowing is confusing. There's a chance this causes some memory to be freed later, but I think it's probably not worth worrying about for now. Differential Revision: https://phab.mercurial-scm.org/D7292

mdiff: mark diffopts as having dynamic attributes This class looks like we could move it to being an attrs and life would be better, but let's do that later. Differential Revision: https://phab.mercurial-scm.org/D7284

vfs: suppress some pytype errors around us using a private attribute Looking at threading._MainThread seems like we're probably a little unsupported, but since this code appears to work on both Python 2 and 3 I'm not going to sweat this for now. Differential Revision: https://phab.mercurial-scm.org/D7282

wireprototypes: disable pytype where it's just confused By inspection validnames is always a Set[bytes] here, but for some reason pytype is convinced it's a bytes. Let's disable the error for now. Differential Revision: https://phab.mercurial-scm.org/D7281

pytype: don't warn us about ignored-on-py3 metaclasses We can remove this when we're Python 3-only, but for now it's just too awkward to deal with and it's harmless. Differential Revision: https://phab.mercurial-scm.org/D7272

linelog: be more careful about types before looking for _target attribute Without this, pytype (correctly) complains that fakejge might not have a _cmprev attribute. We're operating on some constraints not expressible in the type system, so we detect the invalid case and raise a nicer exception now. Sadly, we also need an `assert` to give PyType a clue that we know what we're doing, but I can absolutely live with that. Differential Revision: https://phab.mercurial-scm.org/D7271

linelog: suppress annoying pytype warning about an ignored metaclass This isn't actively hurting us right now, and it's not trivial to set up this metaclass correctly on both Python 2 and Python 3 without dragging in all of `six`, but we still get lots of typechecking goodness with this error suppressed.

hghave: add a check for pytype, Google's Python type checker I'm not unbiased, but I strongly prefer pytype to mypy: it does more inference, so we don't need as many annontations. In theory we can use both, but since I'm doing some tinkering with pytype I figured I'd just try setting it up. Differential Revision: https://phab.mercurial-scm.org/D7268

rust-status: remove dead code The `walk_explicit` function is only called when using a prefix matcher, which the Rust code does not yet support. This function will return in a future patch, probably with a different signature for performance reasons. With it, the `files` argument and its interface code can be removed for now. Differential Revision: https://phab.mercurial-scm.org/D7253

hghave: disallow symlinks on Windows Symlinks on Windows require either a special priviledge, or enabling Developer Mode. It's probably the latter that is enabled on the new CI machine. But since Mercurial itself is saying no to symlinks on Windows, the tests for symlinks shouldn't be attempted. This should fix a lot of the noise in the py3 tests.

repoview: avoid wrapping changelog if there's nothing to filter This simplifies the code a bit by moving the optimizaton for no filtered revisions to one place.
