* gh-114570: Add PythonFinalizationError exception (#115352)Victor Stinner2024-02-141-0/+1
| | | | | | | | | | | | | | | | | Add PythonFinalizationError exception. This exception derived from RuntimeError is raised when an operation is blocked during the Python finalization. The following functions now raise PythonFinalizationError, instead of RuntimeError: * _thread.start_new_thread() * subprocess.Popen * os.fork() * os.fork1() * os.forkpty() Morever, _winapi.Overlapped finalizer now logs an unraisable PythonFinalizationError, instead of an unraisable RuntimeError.

* GH-114456: lower the recursion limit under WASI for debug builds (GH-114457)Brett Cannon2024-01-231-1/+3
| | | Testing under wasmtime 16.0.0 w/ code from https://github.com/python/cpython/issues/114413 is how the value was found.
* gh-89850: Add default C implementations of persistent_id() and ↵Serhiy Storchaka2024-01-101-3/+26
| | | | | | | | | | | persistent_load() (GH-113579) Previously the C implementation of pickle.Pickler and pickle.Unpickler classes did not have such methods and they could only be used if they were overloaded in subclasses or set as instance attributes. Fixed calling super().persistent_id() and super().persistent_load() in subclasses of the C implementation of pickle.Pickler and pickle.Unpickler classes. It no longer causes an infinite recursion.

* GH-84559: Deprecate fork being the multiprocessing default. (#100618)Gregory P. Smith2023-02-021-0/+2
| | | | | | | | This starts the process. Users who don't specify their own start method and use the default on platforms where it is 'fork' will see a DeprecationWarning upon multiprocessing.Pool() construction or upon multiprocessing.Process.start() or concurrent.futures.ProcessPool use. See the related issue and documentation within this change for details.

| | | | | | | | | | | See [PEP 597](https://www.python.org/dev/peps/pep-0597/). * Add `-X warn_default_encoding` and `PYTHONWARNDEFAULTENCODING`. * Add EncodingWarning * Add io.text_encoding() * open(), TextIOWrapper() emits EncodingWarning when encoding is omitted and warn_default_encoding is enabled. * _pyio.TextIOWrapper() uses UTF-8 as fallback default encoding used when failed to import locale module. (used during building Python) * bz2, configparser, gzip, lzma, pathlib, tempfile modules use io.text_encoding(). * What's new entry

* bpo-37210: Fix pure Python pickle when _pickle is unavailable (GH-14016)Victor Stinner2019-06-131-6/+7
| | | | | | | Allow pure Python implementation of pickle to work even when the C _pickle module is unavailable. Fix test_pickle when _pickle is missing: declare PyPicklerHookTests outside "if has_c_implementation:" block.
