util: fix the signature for the pypy override of sortdict.update() PyCharm flagged this as not matching the base class signature. Not sure if there was anything supplying these extra arguments though. Differential Revision: https://phab.mercurial-scm.org/D10275

typing: add type hints to mercurial/error.py The only slightly unusual things here are that `location` is passed to `ParseError` and both bytes and an int (so this accepts both), and the message passed `ProgrammingError` is immediately converted to str. Therefore it is typed as `AnyStr`, because there are a couple of instances that are already passed as str. There are a couple of places where bytes are being passed to builtin exceptions that might need to be converted to str. Differential Revision: https://phab.mercurial-scm.org/D10274

tests: add a (very slow) test that executes pytype This is an updated form of D7295, and completes successfully with pytype 2021.03.22. The 5 or so crashes that were mostly in the hgweb files seems to have been fixed in 2021.03.10. Differential Revision: https://phab.mercurial-scm.org/D10237

upgrade: do not hardcore file extension of revlogs This logic already lives inside the `store` module. So lets reuse it instead. Differential Revision: https://phab.mercurial-scm.org/D10317

upgrade: take advantage of the new information returned by `store.walk` Before this change the upgrade code had to analyse filename to process them directly. Lets keep that logic private to the store and more to a more robust explicit approach. Differential Revision: https://phab.mercurial-scm.org/D10316

store: also return some information about the type of file `walk` found We start returning of 4th information in the `store.walk` return tuple: the type of the file. This will make it easier for caller to determine which kind of file they are looking at. This should especically help with the `upgrade-repo` code that has to do a lot of fragile index's file name comparison. Differential Revision: https://phab.mercurial-scm.org/D10315

tests: skip test-git-interop.t on Windows Casefolding isn't handled in dirstate yet, triggering a bunch of assertions. But while this is more correctly `no-icasefs`, it's more likely to get attention if someone sees it. I'd just rather not have it adding to the noise on Windows for now.

contrib: restore the `hg fix` configuration in the examples After decc3bd3f20d, running `black` will DTRT, but running `hg fix` did nothing (unless the example config file was %included, in which case it truncated the file instead of formatting it). I'm not sure why that was happening, but let's not leave a code shredder laying around. Differential Revision: https://phab.mercurial-scm.org/D10311

blackbox: fix type error on log rotation on read-only filesystem Grepping around, the code uses either encoding.strtolocal or stringutil.forcebytestr in this situation. No idea which is best. Differential Revision: https://phab.mercurial-scm.org/D10293

rust: Remove use of `py.eval()` The previous Rust code allocated an intermediate `Vec`, converted that to a Python list, then used `eval` to run Python code that converts that list to a Python set. rust-cpython exposes Rust bindings for Python sets, let’s use that instead to construct a set directly.
