* add stubs for tracemalloc
This one has especially nice documentation, even including type annotations.
* no PEP 526 so I can run tests locally
* fixes
* another one
* move cgi to 2and3 and add types
This is pretty stable between Python 2 and 3, and not very well documented.
* fix CI failures
* adjust comment
(want to force Travis to re-run)
* give up on overriding values
* add compileall stubs to 3 and add types to the ones in 2
Didn't merge the stubs because all functions have additional parameters since 3.2,
so there would be no shared code between 2 and 3.
* add comment
- Add sys.version_info checks (mypy now supports them)
- Went over Python 3 docs and corrected a few things
- Reexport things that are imported from opcode
This works towards fixing #924. To make the changes easier to review, I'm planning to
fix the issue in two steps:
- This commit makes the 3 stubs compatible with py2
- The next PR will move the 3 stubs to 2and3 and remove the 2 stubs
I wrote this code by diffing the files in third_party/{2,3}/requests and making
appropriate changes to the Python 3 stubs (mostly str/Text stuff). I verified
that the 3 stubs now pass mypy when parsed as 2.7, but I don't have an annotated
requests-using codebase to test on.
CONTRIBUTING.md says to prefer ... Not the most impactful change but fixing
these will allow us to lint for it in the future and get a consistent style.
"> (3,)" works but looks like the code is checking for Python 4.
"<= (3, 5)" was intended to check for versions up to and including 3.5, and probably works that
way in current type checkers. However, sys.version_info is actually a 5-tuple that is greater
than (3, 5), so a hypothetical type checker that uses the full version info would interpret
this check incorrectly.
This ensures that all version_info comparisons use <, >=, ==, or !=.
Closes#953.
I reviewed the documentation at https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.AbstractEventLoop and added missing methods and missing @coroutine decorators.
I ran mypy on the sample file from the issue report to confirm that mypy handles the combination of @abstractmethod and @coroutine correctly.
Also fixed a number of types in this file that are annotated as Any but could be given more precise types (e.g., sockets and protocol factories).
Both mypy and pytype only use the major and minor version in type checking. Using
checks like "sys.version_info >= (3, 4, 4)" won't actually work properly for
people type checking their code using version 3.4, because (3, 4) >= (3, 4, 4) will
always be false (at least in mypy's approach; not sure if pytype is different).
Fixes#975
And a few more things I noticed while reading the tempfile docs.
In 3.5, most functions in tempfile were changed to accept either str or bytes in their prefix and suffix arguments, and return bytes or str accordingly. This seemed like a case for AnyStr.
We were missing tempdirb and tempprefixb, added in 3.5.
TemporaryFile and others were declared as returning BinaryIO, but they actually return either binary or text IO depending on the mode passed in. I changed the return type to IO[Any], similar to builtins.open.
I've seen some stubs like
```
class X:
def __init__(self, x: str) -> None:
self.x = x
self.y = 0
```
I think this should be written instead as
```
class X:
x: str
y: int
def __init__(self, x: str) -> None: ...
```
A previous PR led mypy to refuse to instantiate ChainMap,
because it had unimplemented abstract methods.
This PR adds the abstract methods to the stub,
which is enough to persuade mypy to allow instantiating
ChainMap.
The code for this method starts as follows:
```
@coroutine
def communicate(self, input=None):
if input is not None:
stdin = self._feed_stdin(input)
```
```

* add stubs for Python 2 profile and cProfile
Partially fixes#531. Contrary to the Python 2.7 docs at
https://docs.python.org/2/library/profile.html#module-cProfile,
these modules do not have exactly the same interface. For
example, profile.Profile() does not have an enable() method.
* profile stubs: move to 2and3, add __init__, use private names for typevars
