* bpo-41376: Fix the documentation of `site.getusersitepackages()` (GH-21602)Phil Elson2020-10-081-1/+3
| | | | | | | | | | | | | | | | | | | `site.getusersitepackages()` returns the location of the user-specific site-packages directory even when the user-specific site-packages is disabled. ``` $ python -s -m site sys.path = [ '/home/user/conda/lib/python37.zip', '/home/user/conda/lib/python3.7', '/home/user/conda/lib/python3.7/lib-dynload', '/home/user/conda/lib/python3.7/site-packages', ] USER_BASE: '/home/user/.local' (exists) USER_SITE: '/home/user/.local/lib/python3.7/site-packages' (doesn't exist) ENABLE_USER_SITE: False ``` It was not practical to prevent the function from returning None if user-specific site-packages are disabled, since there are other uses of the function which are relying on this behaviour (e.g. `python -m site`).

| | | | | library numeric types (GH-6121)" (GH-22584) This reverts commit 58a7da9e125422323f79c4ee95ac5549989d8162.
* bpo-41923: PEP 613: Add TypeAlias to typing module (#22532)Mikhail Golubev2020-10-072-2/+36
| | | | | This special marker annotation is intended to help in distinguishing proper PEP 484-compliant type aliases from regular top-level variable assignments.
* bpo-38605: Make 'from __future__ import annotations' the default (GH-20434)Batuhan Taskaya2020-10-062-7/+20
| | | | | The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions. For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).

* bpo-26680: Incorporate is_integer in all built-in and standard library ↵Robert Smallshire2020-10-013-17/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | numeric types (GH-6121) * bpo-26680: Adds support for int.is_integer() for compatibility with float.is_integer(). The int.is_integer() method always returns True. * bpo-26680: Adds a test to ensure that False.is_integer() and True.is_integer() are always True. * bpo-26680: Adds Real.is_integer() with a trivial implementation using conversion to int. This default implementation is intended to reduce the workload for subclass implementers. It is not robust in the presence of infinities or NaNs and may have suboptimal performance for other types. * bpo-26680: Adds Rational.is_integer which returns True if the denominator is one. This implementation assumes the Rational is represented in it's lowest form, as required by the class docstring. * bpo-26680: Adds Integral.is_integer which always returns True. * bpo-26680: Adds tests for Fraction.is_integer called as an instance method. The tests for the Rational abstract base class use an unbound method to sidestep the inability to directly instantiate Rational. These tests check that everything works correct as an instance method. * bpo-26680: Updates documentation for Real.is_integer and built-ins int and float. The call x.is_integer() is now listed in the table of operations which apply to all numeric types except complex, with a reference to the full documentation for Real.is_integer(). Mention of is_integer() has been removed from the section 'Additional Methods on Float'. The documentation for Real.is_integer() describes its purpose, and mentions that it should be overridden for performance reasons, or to handle special values like NaN. * bpo-26680: Adds Decimal.is_integer to the Python and C implementations. The C implementation of Decimal already implements and uses mpd_isinteger internally, we just expose the existing function to Python. The Python implementation uses internal conversion to integer using to_integral_value(). In both cases, the corresponding context methods are also implemented. Tests and documentation are included. * bpo-26680: Updates the ACKS file. * bpo-26680: NEWS entries for int, the numeric ABCs and Decimal. Co-authored-by: Robert Smallshire <rob@sixty-north.com>

* [doc] Leverage the fact that the actual types can now be indexed for typing ↵Andre Delfino2020-09-272-30/+29
| | | | | | | | | | | (GH-22340) This shows users that they can use the actual types. Using deprecated types is confusing. This also prefers colections.abc.Sized instead of the alias typing.Sized. I guess the aliases were created to make it convenient to import all collections related types from the same place. This should be backported to 3.9. Automerge-Triggered-By: @gvanrossum

* bpo-41834: Remove _Py_CheckRecursionLimit variable (GH-22359)Victor Stinner2020-09-231-0/+4
| | | | | | | | | | Remove the global _Py_CheckRecursionLimit variable: it has been replaced by ceval.recursion_limit of the PyInterpreterState structure. There is no need to keep the variable for the stable ABI, since Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() were not usable in Python 3.8 and older: these macros accessed PyThreadState members, whereas the PyThreadState structure is opaque in the limited C API.

* bpo-41756: Introduce PyGen_Send C API (GH-22196)Vladimir Matveev2020-09-192-0/+20
| | | | | | | | | | | | | The new API allows to efficiently send values into native generators and coroutines avoiding use of StopIteration exceptions to signal returns. ceval loop now uses this method instead of the old "private" _PyGen_Send C API. This translates to 1.6x increased performance of 'await' calls in micro-benchmarks. Aside from CPython core improvements, this new API will also allow Cython to generate more efficient code, benefiting high-performance IO libraries like uvloop.
