* gh-100240: Use a consistent implementation for freelists (#121934)Sam Gross2024-07-221-55/+4
| | | | | | | | This combines and updates our freelist handling to use a consistent implementation. Objects in the freelist are linked together using the first word of memory block. If configured with freelists disabled, these operations are essentially no-ops.
* gh-121546: Disable contextvar caching on free-threading build (GH-121740)Ken Jin2024-07-151-0/+14

* gh-119182: Use public PyUnicodeWriter in contextvar_tp_repr() (#120809)Victor Stinner2024-06-201-32/+15
| | | | The public PyUnicodeWriter API enables overallocation by default and so is more efficient. It also makes the code simpler and shorter.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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)
* gh-94673: Hide Objects in PyTypeObject Behind Accessors (gh-104074)Eric Snow2023-05-021-1/+1
| | | This makes it much cleaner to move more PyTypeObject fields to PyInterpreterState.
* gh-81057: Move contextvars-related Globals to _PyRuntimeState (gh-99400)Eric Snow2022-11-161-24/+14
| | | | | This is part of the effort to consolidate global variables, to make them easier to manage (and make it easier to later move some of them to PyInterpreterState). https://github.com/python/cpython/issues/81057
* gh-99300: Use Py_NewRef() in Python/ directory (#99317)Victor Stinner2022-11-101-28/+14
| | | | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in C files of the Python/ directory. Update Parser/asdl_c.py to regenerate Python/Python-ast.c.
* Add more stats for freelist use and allocations. (GH-92211)Mark Shannon2022-05-031-0/+2
|
* bpo-47164: Add _PyCFunction_CAST() macro (GH-32192)Victor Stinner2022-03-311-1/+1
| | | Use the macro in C files of the Python/ directory.
* bpo-46417: Clear more static types (GH-30796)Victor Stinner2022-01-221-16/+3
| | | | | | | * Move PyContext static types into object.c static_types list. * Rename PyContextTokenMissing_Type to _PyContextTokenMissing_Type and declare it in pycore_context.h. * _PyHamtItems types are no long exported: replace PyAPI_DATA() with extern.
* bpo-46008: Make runtime-global object/type lifecycle functions and state ↵Eric Snow2021-12-091-8/+14
| | | | | | | | | | | | consistent. (gh-29998) This change is strictly renames and moving code around. It helps in the following ways: * ensures type-related init functions focus strictly on one of the three aspects (state, objects, types) * passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter * consistent naming conventions help make what's going on more clear * keeping API related to a type in the corresponding header file makes it more obvious where to look for it https://bugs.python.org/issue46008
* bpo-45522: Allow to disable freelists on build time (GH-29056)Christian Heimes2021-10-211-8/+15
| | | | | | | | Freelists for object structs can now be disabled. A new ``configure`` option ``--without-freelists`` can be used to disable all freelists except empty tuple singleton. Internal Py*_MAXFREELIST macros can now be defined as 0 without causing compiler warnings and segfaults. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45439: Move _PyObject_VectorcallTstate() to pycore_call.h (GH-28893)Victor Stinner2021-10-141-1/+1
| | | | | | | | | | | * Move _PyObject_VectorcallTstate() and _PyObject_FastCallTstate() to pycore_call.h (internal C API). * Convert PyObject_CallOneArg(), PyObject_Vectorcall(), _PyObject_FastCall() and PyVectorcall_Function() static inline functions to regular functions. * Add _PyVectorcall_FunctionInline() static inline function. * PyObject_Vectorcall(), _PyObject_FastCall(), and PyObject_CallOneArg() now call _PyThreadState_GET() rather than PyThreadState_Get().
* pycore_pystate.h no longer redefines PyThreadState_GET() (GH-28921)Victor Stinner2021-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | Redefining the PyThreadState_GET() macro in pycore_pystate.h is useless since it doesn't affect files not including it. Either use _PyThreadState_GET() directly, or don't use pycore_pystate.h internal C API. For example, the _testcapi extension don't use the internal C API, but use the public PyThreadState_Get() function instead. Replace PyThreadState_Get() with _PyThreadState_GET(). The _PyThreadState_GET() macro is more efficient than PyThreadState_Get() and PyThreadState_GET() function calls which call fail with a fatal Python error. posixmodule.c and _ctypes extension now include <windows.h> before pycore header files (like pycore_call.h). _PyTraceback_Add() now uses _PyErr_Fetch()/_PyErr_Restore() instead of PyErr_Fetch()/PyErr_Restore(). The _decimal and _xxsubinterpreters extensions are now built with the Py_BUILD_CORE_MODULE macro defined to get access to the internal C API.
* Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)Serhiy Storchaka2021-09-191-2/+2
| | | | | The cast to PyCFunction is redundant. Overuse of redundant casts can hide actual bugs.
* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-6/+6
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.
* bpo-43268: _Py_IsMainInterpreter() now expects interp (GH-24577)Victor Stinner2021-02-191-1/+1
| | | | The _Py_IsMainInterpreter() function now expects interp rather than tstate.
* bpo-1635741: _contextvars uses PyModule_AddType() (GH-23147)Victor Stinner2020-11-041-3/+3
| | | | | | Replace PyModule_AddObject() with PyModule_AddType() in the _contextvars module (Python-ast.c). Add also the module name to _contextvars types name.
* bpo-40521: Fix _PyContext_Fini() (GH-21103)Victor Stinner2020-06-241-1/+3
| | | Only clear _token_missing in the main interpreter.
* bpo-40521: Cleanup code of free lists (GH-21082)Victor Stinner2020-06-231-4/+10
| | | Add get_xxx_state() function to factorize duplicated code.
* bpo-40887: Don't use finalized free lists (GH-20700)Victor Stinner2020-06-081-0/+12
| | | | | | In debug mode, ensure that free lists are no longer used after being finalized. Set numfree to -1 in finalization functions (eg. _PyList_Fini()), and then check that numfree is not equal to -1 before using a free list (e.g list_dealloc()).
* bpo-40521: Make context free list per-interpreter (GH-20644)Victor Stinner2020-06-051-16/+19
| | | | | | | | | Each interpreter now has its own context free list: * Move context free list into PyInterpreterState. * Add _Py_context_state structure. * Add tstate parameter to _PyContext_ClearFreeList() and _PyContext_Fini(). * Pass tstate to clear_freelists().
* bpo-40428: Remove PyTuple_ClearFreeList() function (GH-19769)Victor Stinner2020-04-291-8/+5
| | | | | | | | | | | | | | | | | | | Remove the following function from the C API: * PyAsyncGen_ClearFreeLists() * PyContext_ClearFreeList() * PyDict_ClearFreeList() * PyFloat_ClearFreeList() * PyFrame_ClearFreeList() * PyList_ClearFreeList() * PySet_ClearFreeList() * PyTuple_ClearFreeList() Make these functions private, move them to the internal C API and change their return type to void. Call explicitly PyGC_Collect() to free all free lists. Note: PySet_ClearFreeList() did nothing.
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-39481: PEP 585 for dataclasses, mailbox, contextvars (GH-19425)Ethan Smith2020-04-141-9/+9
|
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-1/+2
|
* bpo-38979: fix ContextVar "__class_getitem__" method (GH-17497)AMIR2019-12-081-3/+4
| | | | | | | | | | now contextvars.ContextVar "__class_getitem__" method returns ContextVar class, not None. https://bugs.python.org/issue38979 Automerge-Triggered-By: @asvetlov
* bpo-38644: Add _PyObject_VectorcallTstate() (GH-17052)Victor Stinner2019-11-081-17/+31
| | | | | * Add _PyObject_VectorcallTstate() function: similar to _PyObject_Vectorcall(), but with tstate parameter * Add tstate parameter to _PyObject_MakeTpCall()
* bpo-36974: implement PEP 590 (GH-13185)Jeroen Demeyer2019-05-291-1/+1
| | | | | Co-authored-by: Jeroen Demeyer <J.Demeyer@UGent.be> Co-authored-by: Mark Shannon <mark@hotpy.org>
* bpo-36101: remove non-ascii characters in docstring (GH-12018)animalize2019-02-241-2/+2
| | | | | * remove non-ascii characters in docstring * clinic.py emits a warning when docstring has non-ascii character
* bpo-33029: Fix signatures of getter and setter functions. (GH-10746)Serhiy Storchaka2018-11-271-2/+2
| | | Fix also return type for few other functions (clear, releasebuffer).
* bpo-33012: Fix invalid function cast warnings with gcc 8. (GH-6749)Serhiy Storchaka2018-11-271-1/+1
| | | | | | Fix invalid function cast warnings with gcc 8 for method conventions different from METH_NOARGS, METH_O and METH_VARARGS excluding Argument Clinic generated code.
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-211-2/+3
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266)Victor Stinner2018-11-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined.
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-3/+3
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* bpo-34762: Fix contextvars C API to use PyObject* pointer types. (GH-9473)Yury Selivanov2018-09-211-23/+62
|
* Add docstrings to public methods from context.c (GH-8531)Peter Lamut2018-07-301-8/+43
|
* bpo-33985: Implement ContextVar.name attribute. (GH-7980)Yury Selivanov2018-06-281-0/+5
|
* Fix some warnings produced by different compilers. (#5593)Serhiy Storchaka2018-02-091-2/+2
|
* bpo-32436: Use PyThreadState_GET() in all hot paths (GH-5363)Yury Selivanov2018-01-271-3/+6
|
* bpo-32436: Make PyContextVar_Get a little bit faster (#5350)Yury Selivanov2018-01-261-1/+2
| | | | Since context.c is compiled with Py_BUILD_CORE, using a macro will result in a slightly more optimal code.
