rust: Upgrade to format-bytes 0.3 This removes use of the proc-macro-hack crate, which is possible now that we don’t support Rust 1.41 to 1.44 anymore. This in turn fixes spurious errors reported by rust-analyser: https://github.com/rust-analyzer/rust-analyzer/issues/9606#issuecomment-919240134 Differential Revision: https://phab.mercurial-scm.org/D11938

pytype: stop excluding ssutil.py Pytype simply can't distinguish the type for this one entry's value from the other values: File "/mnt/c/Users/Matt/hg/mercurial/sslutil.py", line 142, in _hostsettings: No attribute 'append' on None [attribute-error] In Optional[Union[Any, List[nothing], bool, bytes]] File "/mnt/c/Users/Matt/hg/mercurial/sslutil.py", line 142, in _hostsettings: No attribute 'append' on bool [attribute-error] In Optional[Union[Any, List[nothing], bool, bytes]] File "/mnt/c/Users/Matt/hg/mercurial/sslutil.py", line 142, in _hostsettings: No attribute 'append' on bytes [attribute-error] In Optional[Union[Any, List[nothing], bool, bytes]] File "/mnt/c/Users/Matt/hg/mercurial/sslutil.py", line 147, in _hostsettings: No attribute 'append' on None [attribute-error] In Optional[Union[Any, List[Tuple[Any, Any]], bool, bytes]] File "/mnt/c/Users/Matt/hg/mercurial/sslutil.py", line 147, in _hostsettings: No attribute 'append' on bool [attribute-error] In Optional[Union[Any, List[Tuple[Any, Any]], bool, bytes]] File "/mnt/c/Users/Matt/hg/mercurial/sslutil.py", line 147, in _hostsettings: No attribute 'append' on bytes [attribute-error] In Optional[Union[Any, List[Tuple[Any, Any]], bool, bytes]] Differential Revision: https://phab.mercurial-scm.org/D11931

pytype: stop excluding wireprotoserver.py The `config` entry is a 2 part tuple, which has `__iter__()`: File "/mnt/c/Users/Matt/hg/mercurial/wireprotoserver.py", line 253, in _availableapis: No attribute '__iter__' on Callable[[Any, Any], Any] [attribute-error] In Union[Callable[[Any, Any, Any, Any, Any], None], Callable[[Any, Any], Any]] File "/mnt/c/Users/Matt/hg/mercurial/wireprotoserver.py", line 253, in _availableapis: No attribute '__iter__' on Callable[[Any, Any, Any, Any, Any], None] [attribute-error] In Union[Callable[[Any, Any, Any, Any, Any], None], Callable[[Any, Any], Any]] Differential Revision: https://phab.mercurial-scm.org/D11930

pytype: stop excluding pycompat.py Whatever issues were here seem to have been previously fixed. Differential Revision: https://phab.mercurial-scm.org/D11929

procutil: avoid an uninitialized variable usage on tempfile exception If `pycompat.unnamedtempfile()` raises an exception, it would have called `stdin.close()` in the `finally` block without it being initialized first. Differential Revision: https://phab.mercurial-scm.org/D11928

pytype: stop excluding procutil.py This avoids these false warnings: File "/mnt/c/Users/Matt/hg/mercurial/utils/procutil.py", line 78, in <module>: No attribute 'register' on Type[io.BufferedIOBase] [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/utils/procutil.py", line 117, in <module>: No attribute 'register' on Type[io.IOBase] [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/utils/procutil.py", line 770, in runbgcommandpy3: No attribute 'close' on int [attribute-error] In Union[IO[Union[bytes, str]], int] Differential Revision: https://phab.mercurial-scm.org/D11927

pytype: stop excluding chgserver.py This teaches pytype about some lazy initialization, and avoids the following: File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 666, in _checkextensions: No attribute '_hashstate' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 672, in _checkextensions: No attribute '_hashstate' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 677, in _bind: No attribute '_realaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 683, in _bind: No attribute '_realaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 686, in _createsymlink: No attribute '_baseaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 686, in _createsymlink: No attribute '_realaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 688, in _createsymlink: No attribute '_baseaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 689, in _createsymlink: No attribute '_realaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 690, in _createsymlink: No attribute '_baseaddress' on chgunixservicehandler [attribute-error] Differential Revision: https://phab.mercurial-scm.org/D11926

pytype: stop excluding webcommands.py I have no idea why, but asserting that each value added to `emptydirs` is not None didn't fix this: File "/mnt/c/Users/Matt/hg/mercurial/hgweb/webcommands.py", line 621, in dirlist: Function bytes.join was called with the wrong arguments [wrong-arg-types] Expected: (self, iterable: Iterable[bytes]) Actually passed: (self, iterable: List[None]) Differential Revision: https://phab.mercurial-scm.org/D11924

pytype: stop excluding patch.py The underlying `email.generator.BytesGenerator` is documented as requiring an `fp` that accepts bytes, so I'm not sure why pytype is getting confused: File "/mnt/c/Users/Matt/hg/mercurial/patch.py", line 112, in msgfp: Function Generator.__init__ was called with the wrong arguments [wrong-arg-types] Expected: (self, outfp: TextIO, ...)
