* gh-128384: Use a context variable for warnings.catch_warnings (gh-130010)Neil Schemenauer2025-04-091-0/+97
| | | | | | | | | | | | | | | | | | | | Make `warnings.catch_warnings()` use a context variable for holding the warning filtering state if the `sys.flags.context_aware_warnings` flag is set to true. This makes using the context manager thread-safe in multi-threaded programs. Add the `sys.flags.thread_inherit_context` flag. If true, starting a new thread with `threading.Thread` will use a copy of the context from the caller of `Thread.start()`. Both these flags are set to true by default for the free-threaded build and false for the default build. Move the Python implementation of warnings.py into _py_warnings.py. Make _contextvars a builtin module. Co-authored-by: Kumar Aditya <kumaraditya@python.org>

* gh-130163: Fix crashes related to PySys_GetObject() (GH-130503)Serhiy Storchaka2025-02-251-16/+9
| | | | | | | | The use of PySys_GetObject() and _PySys_GetAttr(), which return a borrowed reference, has been replaced by using one of the following functions, which return a strong reference and distinguish a missing attribute from an error: _PySys_GetOptionalAttr(), _PySys_GetOptionalAttrString(), _PySys_GetRequiredAttr(), and _PySys_GetRequiredAttrString().
* gh-111924: Fix data races when swapping allocators (gh-130287)Sam Gross2025-02-201-26/+48
| | | | | | | | | | | | | | | CPython current temporarily changes `PYMEM_DOMAIN_RAW` to the default allocator during initialization and shutdown. The motivation is to ensure that core runtime structures are allocated and freed using the same allocator. However, modifying the current allocator changes global state and is not thread-safe even with the GIL. Other threads may be allocating or freeing objects use PYMEM_DOMAIN_RAW; they are not required to hold the GIL to call PyMem_RawMalloc/PyMem_RawFree. This adds new internal-only functions like `_PyMem_DefaultRawMalloc` that aren't affected by calls to `PyMem_SetAllocator()`, so they're appropriate for Python runtime initialization and finalization. Use these calls in places where we previously swapped to the default raw allocator.

* gh-126925: Modify how iOS test results are gathered (#127592)Russell Keith-Magee2024-12-091-0/+15
| | | | | | | Adds a `use_system_log` config item to enable stdout/stderr redirection for Apple platforms. This log streaming is then used by a new iOS test runner script, allowing the display of test suite output at runtime. The iOS test runner script can be used by any Python project, not just the CPython test suite.
* gh-115999: Implement thread-local bytecode and enable specialization for ↵mpage2024-11-041-2/+47
| | | | | | | | | `BINARY_OP` (#123926) Each thread specializes a thread-local copy of the bytecode, created on the first RESUME, in free-threaded builds. All copies of the bytecode for a code object are stored in the co_tlbc array on the code object. Threads reserve a globally unique index identifying its copy of the bytecode in all co_tlbc arrays at thread creation and release the index at thread destruction. The first entry in every co_tlbc array always points to the "main" copy of the bytecode that is stored at the end of the code object. This ensures that no bytecode is copied for programs that do not use threads. Thread-local bytecode can be disabled at runtime by providing either -X tlbc=0 or PYTHON_TLBC=0. Disabling thread-local bytecode also disables specialization. Concurrent modifications to the bytecode made by the specializing interpreter and instrumentation use atomics, with specialization taking care not to overwrite an instruction that was instrumented concurrently.

* gh-116167: Allow disabling the GIL with `PYTHON_GIL=0` or `-X gil=0` (#116338)Brett Simmers2024-03-111-0/+45
| | | | | | | | | 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-108753: Enhance pystats (#108754)Victor Stinner2023-09-061-2/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Statistics gathering is now off by default. Use the "-X pystats" command line option or set the new PYTHONSTATS environment variable to 1 to turn statistics gathering on at Python startup. Statistics are no longer dumped at exit if statistics gathering was off or statistics have been cleared. Changes: * Add PYTHONSTATS environment variable. * sys._stats_dump() now returns False if statistics are not dumped because they are all equal to zero. * Add PyConfig._pystats member. * Add tests on sys functions and on setting PyConfig._pystats to 1. * Add Include/cpython/pystats.h and Include/internal/pycore_pystats.h header files. * Rename '_py_stats' variable to '_Py_stats'. * Exclude Include/cpython/pystats.h from the Py_LIMITED_API. * Move pystats.h include from object.h to Python.h. * Add _Py_StatsOn() and _Py_StatsOff() functions. Remove '_py_stats_struct' variable from the API: make it static in specialize.c. * Document API in Include/pystats.h and Include/cpython/pystats.h. * Complete pystats documentation in Doc/using/configure.rst. * Don't write "all zeros" stats: if _stats_off() and _stats_clear() or _stats_dump() were called. * _PyEval_Fini() now always call _Py_PrintSpecializationStats() which does nothing if stats are all zeros.

* gh-108634: PyInterpreterState_New() no longer calls Py_FatalError() (#108748)Victor Stinner2023-09-011-7/+20
| | | | | | | | | | | | pycore_create_interpreter() now returns a status, rather than calling Py_FatalError(). * PyInterpreterState_New() now calls Py_ExitStatusException() instead of calling Py_FatalError() directly. * Replace Py_FatalError() with PyStatus in init_interpreter() and _PyObject_InitState(). * _PyErr_SetFromPyStatus() now raises RuntimeError, instead of ValueError. It can now call PyErr_NoMemory(), raise MemoryError, if it detects _PyStatus_NO_MEMORY() error message.

* gh-106320: Remove _PyDict_GetItemStringWithError() function (#108313)Victor Stinner2023-08-221-0/+1
| | | | | | | | | Remove private _PyDict_GetItemStringWithError() function of the public C API: the new PyDict_GetItemStringRef() can be used instead. * Move private _PyDict_GetItemStringWithError() to the internal C API. * _testcapi get_code_extra_index() uses PyDict_GetItemStringRef(). Avoid using private functions in _testcapi which tests the public C API.
