* gh-116167: Allow disabling the GIL with `PYTHON_GIL=0` or `-X gil=0` (#116338)Brett Simmers2024-03-11
| | | | | | | | | In free-threaded builds, running with `PYTHON_GIL=0` will now disable the GIL. Follow-up issues track work to re-enable the GIL when loading an incompatible extension, and to disable the GIL by default. In order to support re-enabling the GIL at runtime, all GIL-related data structures are initialized as usual, and disabling the GIL simply sets a flag that causes `take_gil()` and `drop_gil()` to return early.
* gh-107954: Add PyConfig_MEMBER_BOOL type to PyConfigSpec (#116359)Victor Stinner2024-03-06
| | | | | | _PyConfig_AsDict() now returns bool objects for options using the new PyConfig_MEMBER_BOOL type. Update tests for these changes.

* gh-90815: Add mimalloc memory allocator (#109914)Dino Viehland2023-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add mimalloc v2.12 Modified src/alloc.c to remove include of alloc-override.c and not compile new handler. Did not include the following files: - include/mimalloc-new-delete.h - include/mimalloc-override.h - src/alloc-override-osx.c - src/alloc-override.c - src/static.c - src/region.c mimalloc is thread safe and shares a single heap across all runtimes, therefore finalization and getting global allocated blocks across all runtimes is different. * mimalloc: minimal changes for use in Python: - remove debug spam for freeing large allocations - use same bytes (0xDD) for freed allocations in CPython and mimalloc This is important for the test_capi debug memory tests * Don't export mimalloc symbol in libpython. * Enable mimalloc as Python allocator option. * Add mimalloc MIT license. * Log mimalloc in Lib/test/pythoninfo.py. * Document new mimalloc support. * Use macro defs for exports as done in: https://github.com/python/cpython/pull/31164/ Co-authored-by: Sam Gross <colesbury@gmail.com> Co-authored-by: Christian Heimes <christian@python.org> Co-authored-by: Victor Stinner <vstinner@python.org>

* gh-106320: Remove private _PyMem API (#107187)Victor Stinner2023-07-24
| | | | | | | | | | | | | Move private _PyMem functions to the internal C API (pycore_pymem.h): * _PyMem_GetCurrentAllocatorName() * _PyMem_RawStrdup() * _PyMem_RawWcsdup() * _PyMem_Strdup() No longer export these functions. Move pymem_getallocatorsname() function from _testcapi to _testinternalcapi, since the API moved to the internal C API.
* gh-96512: Move int_max_str_digits setting to PyConfig (#96944)Gregory P. Smith2022-10-03
| | | | | | | | | | | It had to live as a global outside of PyConfig for stable ABI reasons in the pre-3.12 backports. This removes the `_Py_global_config_int_max_str_digits` and gets rid of the equivalent field in the internal `struct _is PyInterpreterState` as code can just use the existing nested config struct within that. Adds tests to verify unique settings and configs in subinterpreters.
* gh-96848: Fix -X int_max_str_digits option parsing (#96988)Victor Stinner2022-09-26
| | | | | Fix command line parsing: reject "-X int_max_str_digits" option with no value (invalid) when the PYTHONINTMAXSTRDIGITS environment variable is set to a valid limit.
* gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96499)Gregory P. Smith2022-09-02
| | | | | | | | | | | | | | | | 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.

* gh-57684: Add -P cmdline option and PYTHONSAFEPATH env var (#31542)Victor Stinner2022-05-06
| | | | | | | | | | | | Add the -P command line option and the PYTHONSAFEPATH environment variable to not prepend a potentially unsafe path to sys.path. * Add sys.flags.safe_path flag. * Add PyConfig.safe_path member. * Programs/_bootstrap_python.c uses config.safe_path=0. * Update subprocess._optim_args_from_interpreter_flags() to handle the -P command line option. * Modules/getpath.py sets safe_path to 1 if a "._pth" file is present.

| | | | | | | | | Instead of explicitly enumerate test classes for run_unittest() use the unittest ability to discover tests. This also makes these tests discoverable and runnable with unittest. load_tests() can be used for dynamic generating tests and adding doctests. setUpModule(), tearDownModule() and addModuleCleanup() can be used for running code before and after all module tests.

* bpo-35883: Py_DecodeLocale() escapes invalid Unicode characters (GH-24843)Victor Stinner2021-03-17
| | | | | | | | | | Python no longer fails at startup with a fatal error if a command line argument contains an invalid Unicode character. The Py_DecodeLocale() function now escapes byte sequences which would be decoded as Unicode characters outside the [U+0000; U+10ffff] range. Use MAX_UNICODE constant in unicodeobject.c.

* bpo-32381: pymain_run_command() uses PyCF_IGNORE_COOKIE (GH-23724)Victor Stinner2020-12-23
| | | | | | | | | | The coding cookie (ex: "# coding: latin1") is now ignored in the command passed to the -c command line option. Since pymain_run_command() uses UTF-8, pass PyCF_IGNORE_COOKIE compiler flag to the parser. pymain_run_python() no longer propages compiler flags between function calls.

* bpo-34589: Add -X coerce_c_locale command line option (GH-9378)Victor Stinner2018-09-17
| | | | Add a new -X coerce_c_locale command line option to control C locale coercion (PEP 538).
* bpo-34170: Enhance _PyCoreConfig_Read() (GH-8468)Victor Stinner2018-07-26
| | | | | | | | | | | | * Inline cmdline_get_env_flags() into config_read_env_vars(): _PyCoreConfig_Read() now reads much more environment variables like PYTHONVERBOSE. * Allow to override faulthandler and allocator even if dev_mode=1. PYTHONMALLOC is now the priority over PYTHONDEVMODE. * Fix _PyCoreConfig_Copy(): copy also install_signal_handlers, coerce_c_locale and coerce_c_locale_warn * _PyCoreConfig.install_signal_handlers default is now 1: install signals by default * Fix also a compiler warning: don't define _PyPathConfig type twice.
* bpo-34170: Add _PyCoreConfig.bytes_warning (GH-8447)Victor Stinner2018-07-25

These functions have been replaced by _PyCoreConfig_GetGlobalConfig() and _PyCoreConfig_SetGlobalConfig(). * sys.flags.dont_write_bytecode value is now restricted to 1 even if -B option is specified multiple times on the command line. * PyThreadState_Clear() now uses the config from the current interpreter rather than using global Py_VerboseFlag
