Michael LeeandJelle Zijlstra fb92ee84c5 Make overloads in the Python 2 builtins with a 'None' fallback come first (#2261) 
In short, this change makes sure calls like `map(None, a, b)` behave as
expected when using `--no-strict-optional` is enabled.

Philipp HahnandJelle Zijlstra 7c3edba6ce python2/gettext improvements (#2235) 
* py2: gettext: info()

returns a Dict[str, str]

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.info>
> Return the “protected” _info variable.

<https://docs.python.org/2/library/gettext.html#the-gnutranslations-class>
> The entire set of key/value pairs are placed into a dictionary and set

* py2: gettext: charset()

returns an Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.charset>
> Return the “protected” _charset variable.

<https://docs.python.org/2/library/gettext.html#the-gnutranslations-class>
> If the key Content-Type is found, then the charset property is used to

* py2: gettext: [set_]output_charset()

allows to set an Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.output_charset>
> Return the “protected” _output_charset variable.

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.set_output_charset>
> Change the “protected” _output_charset variable, which defines the
> encoding used to return translated messages.

<https://docs.python.org/2/library/gettext.html#gettext.GNUTranslations.lgettext>
> Equivalent to gettext(), but the translation is returned in the
> preferred system encoding, if no other encoding was explicitly set with
> set_output_charset().

* py2: gettext: install(..., names)

allows to set an Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.install>
> If the names parameter is given, it must be a sequence containing the
> names of functions you want to install in the builtins namespace in
> addition to _().

* py2: gettext: localdir=None

is Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.bindtextdomain>
> If localedir is omitted or None, then the current binding for domain
> is returned.

* py2: gettext: languages=None

is Optional[Sequence[str]]

<https://docs.python.org/2/library/gettext.html#gettext.find>
> If languages is not given, then the following environment variables
> are searched: ...

* py2: gettext: codeset=None

is Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.translation>
> If provided, codeset will change the charset used to encode translated
> strings.

* py2: gettext: translation(class_=None)

is Optional[type]

<https://docs.python.org/2/library/gettext.html#gettext.translation>
> The actual class instantiated is either class_ if provided, otherwise
> GNUTranslations.

* py2: gettext: translation(fallback)

is bool

<https://docs.python.org/2/library/gettext.html#gettext.translation>
> ..., this function raises IOError if fallback is false (which is the
> default), and returns a NullTranslations instance if fallback is true.

* py2: gettext: install(unicode)

is bool

<https://docs.python.org/2/library/gettext.html#gettext.install>
> The unicode flag is passed to the resulting translation object’s
> install() method.

which is already expecting `bool`.

Anthony SottileandJelle Zijlstra 56c93c85c0 Add NoReturn to execv* family of functions (#2226) 2018-06-15 07:55:45 -07:00
Jelle ZijlstraandGuido van Rossum d2469c0e89 fix type for itertools.product (#2129) 
Fixes #1850.

The fix was already applied to Python 2, but the typevar-based solution there
leads to "cannot infer value of type variable" in mypy. I used the following
script to check:

```python
from itertools import product

reveal_type(product([1]))
reveal_type(product([1], ['x'], [False], [3.0], [(1,)], [('x',)], [{1}], [{1: 2}], repeat=5))
```

Michael J. SullivanandGitHub 2ba90a65c0 Remove __all__ = ... from stubs (#2161) 
The presence of a __all__ causes everything to not get picked up by
import *, which among other things breaks the new six.moves stubs.

Michael J. SullivanandGitHub db1316d26b os.path.relpath can use a default argument and still use str (#2159) 2018-05-24 13:23:17 -07:00
Jelle ZijlstraandGuido van Rossum b89f9553e9 keep os.path in 2 and 3 consistent (#2152) 
We can't merge these because os/__init__ is still different.

Also slight refactor of tests/check_consistent.py to avoid `from os import path`.

Michael LeeandJelle Zijlstra 709b193416 Rearrange overloads to account for optional arguments (#2150) 
Basically, the same thing as [my previous pull request][0], except the
fixes are now focusing on functions with overlapping argument counts.

Semyon ProshevandJelle Zijlstra 9275be244f Update NamedTuple _make and _replace parameters in Python 2 (#2144) 2018-05-17 11:03:55 -07:00
Michael LeeandJelle Zijlstra 97d9f2eb2c Ensures overloads are ordered from narrow to broad (#2138) 
This commit reorders any overloads where the first overload was
"shadowing" the second, preventing it from ever being matched by type
checkers that work by selecting the first matching overload alternative.

For example, the first overload alternative below is strictly broader
then the second, preventing it from ever being selected:

    class Parent: pass
    class Child(Parent): pass

    @overload
    def foo(x: *int) -> Parent: ...
    @overload
    def foo(x: int, y: int) -> Child: ...

The correct thing to do is to either delete the second overload or
rearrange them to look like this:

    @overload
    def foo(x: int, y: int) -> Child: ...
    @overload
    def foo(x: *int) -> Parent: ...

Rationale: I'm currently [working on a proposal][0] that would amend
PEP 484 to (a) mandate type checkers check overloads in order and
(b) prohibit overloads where an earlier alternative completely shadows
a later one.

  [0]: https://github.com/python/typing/issues/253#issuecomment-389262904

This would prohibit overloads that look like the example below, where
the first alternative completely shadows the second.

I figured it would be a good idea to make these changes ahead of time:
if my proposal is accepted, it'd make the transition smoother. If not,
this is hopefully a relatively harmless change.

Note: I think some of these overloads could be simplified (e.g.
`reversed(...)`), but I mostly stuck with rearranging them in case I was
wrong. The only overload I actually changed was `hmac.compare_digest` --
I believe the Python 2 version actually accepts unicode.

Jelle ZijlstraandGitHub 55be42f6d6 add __fspath__ support to os.path (#2053) 
Fixes #1997, #2068.

This is tricky because we need to get the return values right (see #1960 for
prior attempts) and we often run into python/mypy#3644. I found that I
could express most signatures correctly using a series of overloads.

A few other changes in here:
- Added splitunc, which according to https://docs.python.org/3/library/os.path.html
  should exist in both Unix and Windows.
- Made the second argument to os.path.curdir Optional to match the implementation.
- Fixed os.path.split, whose previous Path-aware signature triggered python/mypy#3644.
