* [3.12] gh-80527: Change support.requires_legacy_unicode_capi() (GH-108438) ↵Miss Islington (bot)2023-08-251-2/+2
| | | | | | | | | | | | | | | | | | | | (#108446) gh-80527: Change support.requires_legacy_unicode_capi() (GH-108438) The decorator now requires to be called with parenthesis: @support.requires_legacy_unicode_capi() instead of: @support.requires_legacy_unicode_capi The implementation now only imports _testcapi when the decorator is called, so "import test.support" no longer imports the _testcapi extension. (cherry picked from commit 995f4c48e11349fbfb9233e02b732d4534d3008e) Co-authored-by: Victor Stinner <vstinner@python.org>

* gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96499)Gregory P. Smith2022-09-021-0/+18
| | | | | | | | | | | | | | | | Integer to and from text conversions via CPython's bignum `int` type is not safe against denial of service attacks due to malicious input. Very large input strings with hundred thousands of digits can consume several CPU seconds. This PR comes fresh from a pile of work done in our private PSRT security response team repo. Signed-off-by: Christian Heimes [Red Hat] <christian@python.org> Tons-of-polishing-up-by: Gregory P. Smith [Google] <greg@krypto.org> Reviews via the private PSRT repo via many others (see the NEWS entry in the PR). <!-- gh-issue-number: gh-95778 --> * Issue: gh-95778 <!-- /gh-issue-number --> I wrote up [a one pager for the release managers](https://docs.google.com/document/d/1KjuF_aXlzPUxTK4BMgezGJ2Pn7uevfX7g0_mvgHlL7Y/edit#). Much of that text wound up in the Issue. Backports PRs already exist. See the issue for links.

* gh-91821: Make decimal test succeed consistently (#91825)Jelle Zijlstra2022-04-241-0/+1
| | | | | | | The test relies on precision being set to 9, but some ways of invoking this test leave it set to 28 instead. I don't know exactly how it happens, but setting the precision directly should make the behavior consistent.

* bpo-45995: add "z" format specifer to coerce negative 0 to zero (GH-30049)John Belmonte2022-04-111-0/+60
| | | | | | | | Add "z" format specifier to coerce negative 0 to zero. See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995) for discussion. This covers `str.format()` and f-strings. Old-style string interpolation is not supported. Co-authored-by: Mark Dickinson <dickinsm@gmail.com>

| | | | | | | | (GH-26783) * When trying to allocate very large regions on macOS, malloc does not fail silently. It sends a noisy error out to STDERR * This provides a helper function to warn the user, and provides the warning for test_decimal, which consistently generates these warnings on macOS.

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>

As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135
