* [3.10] GH-99086: Fix -Wstrict-prototypes, -Wimplicit-function-declara… ↵Sam James2024-03-191-26/+31
| | | | | | | | | | | (#99920) [3.10] gh-99086: Fix -Wstrict-prototypes, -Wimplicit-function-declaration warnings in configure.ac (GH-99406) Follow up to 12078e78f6e4a21f344e4eaff529e1ff3b97734f.

* bpo-42856: Add --with-wheel-pkg-dir=PATH configure option (GH-24210)Victor Stinner2024-03-191-0/+16
| | | | | | | | | | | | | | | | Add --with-wheel-pkg-dir=PATH option to the ./configure script. If specified, the ensurepip module looks for setuptools and pip wheel packages in this directory: if both are present, these wheel packages are used instead of ensurepip bundled wheel packages. Some Linux distribution packaging policies recommend against bundling dependencies. For example, Fedora installs wheel packages in the /usr/share/python-wheels/ directory and don't install the ensurepip._bundled package. ensurepip: Remove unused runpy import. backported to 3.9 by Michał Górny

* bpo-43998: Default to TLS 1.2 and increase cipher suite security (GH-25778)Christian Heimes2024-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ssl module now has more secure default settings. Ciphers without forward secrecy or SHA-1 MAC are disabled by default. Security level 2 prohibits weak RSA, DH, and ECC keys with less than 112 bits of security. :class:`~ssl.SSLContext` defaults to minimum protocol version TLS 1.2.

* bpo-41710: PyThread_acquire_lock_timed() uses sem_clockwait() (GH-28671) ↵Miss Islington (bot)2021-10-011-1/+1
| | | | | | | | | | | | | | (GH-28683) On Unix, if the sem_clockwait() function is available in the C library (glibc 2.30 and newer), the threading.Lock.acquire() method now uses the monotonic clock (time.CLOCK_MONOTONIC) for the timeout, rather than using the system clock (time.CLOCK_REALTIME), to not be affected by system clock changes. configure now checks if the sem_clockwait() function is available.

* bpo-40503: PEP 615: Tests and implementation for zoneinfo (GH-19909)Paul Ganssle2020-05-161-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial implementation of PEP 615, the zoneinfo module, ported from the standalone reference implementation (see https://www.python.org/dev/peps/pep-0615/#reference-implementation for a link, which has a more detailed commit history). This includes (hopefully) all functional elements described in the PEP, but documentation is found in a separate PR. This includes: 1. A pure python implementation of the ZoneInfo class 2. A C accelerated implementation of the ZoneInfo class 3. Tests with 100% branch coverage for the Python code (though C code coverage is less than 100%). 4. A compile-time configuration option on Linux (though not on Windows) Differences from the reference implementation: - The module is arranged slightly differently: the accelerated module is `_zoneinfo` rather than `zoneinfo._czoneinfo`, which also necessitates some changes in the test support function. (Suggested by Victor Stinner and Steve Dower.) - The tests are arranged slightly differently and do not include the property tests. The tests live at test/test_zoneinfo/test_zoneinfo.py rather than test/test_zoneinfo.py or test/test_zoneinfo/__init__.py because we may do some refactoring in the future that would likely require this separation anyway; we may: - include the property tests - automatically run all the tests against both pure Python and C, rather than manually constructing C and Python test classes (similar to the way this works with test_datetime.py, which generates C and Python test cases from datetimetester.py). - This includes a compile-time configuration option on Linux (though not on Windows); added with much help from Thomas Wouters. - Integration into the CPython build system is obviously different from building a standalone zoneinfo module wheel. - This includes configuration to install the tzdata package as part of CI, though only on the coverage jobs. Introducing a PyPI dependency as part of the CI build was controversial, and this is seen as less of a major change, since the coverage jobs already depend on pip and PyPI. Additional changes that were introduced as part of this PR, most / all of which were backported to the reference implementation: - Fixed reference and memory leaks With much debugging help from Pablo Galindo - Added smoke tests ensuring that the C and Python modules are built The import machinery can be somewhat fragile, and the "seamlessly falls back to pure Python" nature of this module makes it so that a problem building the C extension or a failure to import the pure Python version might easily go unnoticed. - Adjustments to zoneinfo.__dir__ Suggested by Petr Viktorin. - Slight refactorings as suggested by Steve Dower. - Removed unnecessary if check on std_abbr Discovered this because of a missing line in branch coverage.
