* bpo-41867: List options for timespec in docstrings of isoformat methods ↵Ram Rachum2020-10-031-4/+8
| | | | (GH-22418)
* Update link to supporting references (GH-22488)Raymond Hettinger2020-10-021-1/+1

* bpo-26680: Incorporate is_integer in all built-in and standard library ↵Robert Smallshire2020-10-012-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* bpo-41815: SQLite: segfault if backup called on closed database (GH-22322)Peter McCormick2020-09-201-0/+4
| | | | | | | | | | | | | # [bpo-41815](): SQLite: fix segfault if backup called on closed database Attempting to backup a closed database will trigger segfault: ```python import sqlite3 target = sqlite3.connect(':memory:') source = sqlite3.connect(':memory:') source.close() source.backup(target) ```
* bpo-41756: Introduce PyGen_Send C API (GH-22196)Vladimir Matveev2020-09-191-5/+22
| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | * Fix refleak in C module __init_subclass__ This was leaking a reference to the weak cache dictionary for every ZoneInfo subclass created. * Fix refleak in ZoneInfo subclass's clear_cache The previous version of the code accidentally cleared the global ZONEINFO_STRONG_CACHE variable (and inducing `ZoneInfo` to create a new strong cache) on calls to a subclass's `clear_cache()`. This would not affect guaranteed behavior, but it's still not the right thing to do (and it caused reference leaks).
