* gh-117398: Use Per-Interpreter State for the _datetime Static Types (gh-119929)Eric Snow2024-06-031-1/+1
| | | | | | | We make use of the same mechanism that we use for the static builtin types. This required a few tweaks. The relevant code could use some cleanup but I opted to avoid the significant churn in this change. I'll tackle that separately. This change is the final piece needed to make _datetime support multiple interpreters. I've updated the module slot accordingly.
* gh-118702: Implement vectorcall for BaseException (#118703)Victor Stinner2024-05-101-0/+40
| | | | | | | | | | * BaseException_vectorcall() now creates a tuple from 'args' array. * Creation an exception using BaseException_vectorcall() is now a single function call, rather than having to call BaseException_new() and then BaseException_init(). Calling BaseException_init() is inefficient since it overrides the 'args' attribute. * _PyErr_SetKeyError() now uses PyObject_CallOneArg() to create the KeyError instance to use BaseException_vectorcall().
* gh-114570: Add PythonFinalizationError exception (#115352)Victor Stinner2024-02-141-0/+5
| | | | | | | | | | | | | | | | | 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-89240: Enable multiprocessing on Windows to use large process pools ↵Steve Dower2024-02-131-4/+3
| | | | | | | (GH-107873) We add _winapi.BatchedWaitForMultipleObjects to wait for larger numbers of handles. This is an internal module, hence undocumented, and should be used with caution. Check the docstring for info before using BatchedWaitForMultipleObjects.

| | | | | | | | | | | | (gh-110911) Fixes #109894 * set `interp.static_objects.last_resort_memory_error.args` to empty tuple to avoid crash on `PyErr_Display()` call * allow `_PyExc_InitGlobalObjects()` to be called on subinterpreter init --------- Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com>
* gh-110964: Remove private _PyArg functions (#110966)Victor Stinner2023-10-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the following private functions and structures to pycore_modsupport.h internal C API: * _PyArg_BadArgument() * _PyArg_CheckPositional() * _PyArg_NoKeywords() * _PyArg_NoPositional() * _PyArg_ParseStack() * _PyArg_ParseStackAndKeywords() * _PyArg_Parser structure * _PyArg_UnpackKeywords() * _PyArg_UnpackKeywordsWithVararg() * _PyArg_UnpackStack() * _Py_ANY_VARARGS() Changes: * Python/getargs.h now includes pycore_modsupport.h to export functions. * clinic.py now adds pycore_modsupport.h when one of these functions is used. * Add pycore_modsupport.h includes when a C extension uses one of these functions. * Define Py_BUILD_CORE_MODULE in C extensions which now include directly or indirectly (via code generated by Argument Clinic) pycore_modsupport.h: * _csv * _curses_panel * _dbm * _gdbm * _multiprocessing.posixshmem * _sqlite.row * _statistics * grp * resource * syslog * _testcapi: bad_get() no longer uses METH_FASTCALL calling convention but METH_VARARGS. Replace _PyArg_UnpackStack() with PyArg_ParseTuple(). * _testcapi: add PYTESTCAPI_NEED_INTERNAL_API macro which is defined by _testcapi sub-modules which need the internal C API (pycore_modsupport.h): exceptions.c, float.c, vectorcall.c, watchers.c. * Remove Include/cpython/modsupport.h header file. Include/modsupport.h no longer includes the removed header file. * Fix mypy clinic.py
* gh-106869: Use new PyMemberDef constant names (#106871)Victor Stinner2023-07-251-31/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove '#include "structmember.h"'. * If needed, add <stddef.h> to get offsetof() function. * Update Parser/asdl_c.py to regenerate Python/Python-ast.c. * Replace: * T_SHORT => Py_T_SHORT * T_INT => Py_T_INT * T_LONG => Py_T_LONG * T_FLOAT => Py_T_FLOAT * T_DOUBLE => Py_T_DOUBLE * T_STRING => Py_T_STRING * T_OBJECT => _Py_T_OBJECT * T_CHAR => Py_T_CHAR * T_BYTE => Py_T_BYTE * T_UBYTE => Py_T_UBYTE * T_USHORT => Py_T_USHORT * T_UINT => Py_T_UINT * T_ULONG => Py_T_ULONG * T_STRING_INPLACE => Py_T_STRING_INPLACE * T_BOOL => Py_T_BOOL * T_OBJECT_EX => Py_T_OBJECT_EX * T_LONGLONG => Py_T_LONGLONG * T_ULONGLONG => Py_T_ULONGLONG * T_PYSSIZET => Py_T_PYSSIZET * T_NONE => _Py_T_NONE * READONLY => Py_READONLY * PY_AUDIT_READ => Py_AUDIT_READ * READ_RESTRICTED => Py_AUDIT_READ * PY_WRITE_RESTRICTED => _Py_WRITE_RESTRICTED * RESTRICTED => (READ_RESTRICTED | _Py_WRITE_RESTRICTED)

* fix typos (#106247)Inada Naoki2023-06-301-1/+1
| | | Most typos are in comments, but two typos are in docstring.
* gh-106084: Remove _PyObject_RealIsInstance() function (#106106)Victor Stinner2023-06-261-0/+1
| | | | | | | | | | | | | | | Remove the following functions from the public C API: * _PyObject_RealIsInstance() * _PyObject_RealIsSubclass() * _Py_add_one_to_index_F() * _Py_add_one_to_index_C() Move _PyObject_RealIsInstance() and _PyObject_RealIsSubclass() to the internal C API (pycore_abstract.h) and no longer export their symbols (in libpython). Make _Py_add_one_to_index_F() and _Py_add_one_to_index_C() functions static: no longer export them.
* gh-105730: support more callables in ExceptionGroup.split() and subgroup() ↵Irit Katriel2023-06-231-3/+3
| | | | (#106035)
* gh-106033: Get rid of new occurrences of PyDict_GetItem and PyObject_HasAttr ↵Serhiy Storchaka2023-06-231-16/+15
| | | | | | | | (GH-106034) These functions are broken by design because they discard any exceptions raised inside, including MemoryError and KeyboardInterrupt. They should not be used in new code.
* gh-92536: Remove PyUnicode_READY() calls (#105210)Victor Stinner2023-06-011-2/+0
| | | | Since Python 3.12, PyUnicode_READY() does nothing and always returns 0.

* gh-94673: Properly Initialize and Finalize Static Builtin Types for Each ↵Eric Snow2023-05-021-6/+2
| | | | | Interpreter (gh-104072) Until now, we haven't been initializing nor finalizing the per-interpreter state properly.
* gh-94673: Ensure Builtin Static Types are Readied Properly (gh-103940)Eric Snow2023-04-271-4/+0
| | | There were cases where we do unnecessary work for builtin static types. This also simplifies some work necessary for a per-interpreter GIL.

* gh-90110: Fix the c-analyzer Tool (#102483)Eric Snow2023-03-071-9/+4
| | | | | | | Some incompatible changes had gone in, and the "ignore" lists weren't properly undated. This change fixes that. It's necessary prior to enabling test_check_c_globals, which I hope to do soon. Note that this does include moving last_resort_memory_error to PyInterpreterState. https://github.com/python/cpython/issues/90110
* GH-101578: Normalize the current exception (GH-101607)Mark Shannon2023-02-081-12/+63
| | | | | | | | | | * Make sure that the current exception is always normalized. * Remove redundant type and traceback fields for the current exception. * Add new API functions: PyErr_GetRaisedException, PyErr_SetRaisedException * Add new API functions: PyException_GetArgs, PyException_SetArgs
* gh-99553: fix bug where an ExceptionGroup subclass can wrap a BaseException ↵Irit Katriel2022-11-181-1/+13

* gh-96005: Handle WASI ENOTCAPABLE in getpath (GH-96006)Christian Heimes2022-08-161-0/+5
| | | | | | - On WASI `ENOTCAPABLE` is now mapped to `PermissionError`. - The `errno` modules exposes the new error number. - `getpath.py` now ignores `PermissionError` when it cannot open landmark files `pybuilddir.txt` and `pyenv.cfg`.
* gh-95369: add missing decref in error case of exception group's split (GH-95370)Irit Katriel2022-07-281-0/+1

* gh-94673: Add _PyStaticType_InitBuiltin() (#95152)Eric Snow2022-07-251-2/+1
| | | | | | | | | | | | This is the first of several precursors to storing tp_subclasses (and tp_weaklist) on the interpreter state for static builtin types. We do the following: * add `_PyStaticType_InitBuiltin()` * add `_Py_TPFLAGS_STATIC_BUILTIN` * set it on all static builtin types in `_PyStaticType_InitBuiltin()` * shuffle some code around to be able to use _PyStaticType_InitBuiltin() * rename `_PyStructSequence_InitType()` to `_PyStructSequence_InitBuiltinWithFlags()` * add `_PyStructSequence_InitBuiltin()`.

* Use static inline function Py_EnterRecursiveCall() (#91988)Victor Stinner2022-05-041-5/+6
| | | | | | | | | | | | | | | | Currently, calling Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() may use a function call or a static inline function call, depending if the internal pycore_ceval.h header file is included or not. Use a different name for the static inline function to ensure that the static inline function is always used in Python internals for best performance. Similar approach than PyThreadState_GET() (function call) and _PyThreadState_GET() (static inline function). * Rename _Py_EnterRecursiveCall() to _Py_EnterRecursiveCallTstate() * Rename _Py_LeaveRecursiveCall() to _Py_LeaveRecursiveCallTstate() * pycore_ceval.h: Rename Py_EnterRecursiveCall() to _Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() and _Py_LeaveRecursiveCall()
