The function `threading.setprofile` can be called with a `None` value to
clear the profile function. This does unset the function from the
existing threads, it only clears the callback function so that new
threads are created without the profiling hook installed.
* Remove custom _Text type
Since the custom type was only used in argument types, it was
effectively only an alias for typing.Text.
* Run requests/api.pyi through black
* Update how mock classes alias to Any
> First, the z: Any situation looks like a bug or accidental feature to me.
This is definitely meant (and works) as a variable declaration; that it
also allows using z as a type seems wrong. I can't find any evidence in
PEP 484 that this was intended; in mypy it's likely the accidental result
of other design choices meant to shut up errors about Any.
Ideally these classes could be declared as empty class stubs, but since the comments suggest this isn't possible yet, let's update these to be type aliases to Any rather than global variables of type Any. This would avoid invalid type errors when the implementation of type checkers respect the intention that `z: Any` does not make `z` a valid type.
* Update mock.pyi
This commit adds:
* Stubs for CGIHTTPServer in the Python 2 standard library, as requested in #1147.
* Stubs for six.moves.CGIHTTPServer in Python 2, as requested in #22.
This pull request is a follow-up to https://github.com/python/mypy/issues/7214.
In short, within that mypy issue, we found it would be helpful to
determine between contextmanagers that can "swallow" exceptions vs ones
that can't. This helps prevent some false positive when using flags that
analyze control flow such as `--warn-unreachable`. To do this,
Jelle proposed assuming that only contextmanagers where the `__exit__`
returns `bool` are assumed to swallow exceptions.
This unfortunately required the following typeshed changes:
1. The typing.IO, threading.Lock, and concurrent.futures.Executor
were all modified so `__exit__` returns `Optional[None]` instead
of None -- along with all of their subclasses.
I believe these three types are meant to be subclassed, so I felt
picking the more general type was correct.
2. There were also a few concrete types (e.g. see socketserver,
subprocess, ftplib...) that I modified to return `None` -- I checked
the source code, and these all seem to return None (and don't appear
to be meant to be subclassable).
3. contextlib.suppress was changed to return bool. I also double-checked
the unittest modules and modified a subset of those contextmanagers,
leaving ones like `_AssertRaisesContext` alone.
Per the docs, globals/locals is an optional argument.
Additionally, globals/locals can be any mapping type, not only a dict.
Likewise, fromlist can be any sequence (the docs mention a tuple, not a
list).
The function returns a ModuleType, not Any.
