* gh-118527: Intern code consts in free-threaded build (#118667)Sam Gross2024-05-071-0/+13
| | | | | | We already intern and immortalize most string constants. In the free-threaded build, other constants can be a source of reference count contention because they are shared by all threads running the same code objects.
* gh-116322: Rename PyModule_ExperimentalSetGIL to PyUnstable_Module_SetGIL ↵Petr Viktorin2024-05-061-1/+1
| | | | (GH-118645)
* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-0/+3
| | | | | | | | | | | | | | This PR adds the ability to enable the GIL if it was disabled at interpreter startup, and modifies the multi-phase module initialization path to enable the GIL when loading a module, unless that module's spec includes a slot indicating it can run safely without the GIL. PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148. A warning will be issued up to once per interpreter for the first GIL-using module that is loaded. If `-v` is given, a shorter message will be printed to stderr every time a GIL-using module is loaded (including the first one that issues a warning).

* gh-76763: Make chr() always raising ValueError for out-of-range values ↵Serhiy Storchaka2024-02-101-4/+21
| | | | | | (GH-114882) Previously it raised OverflowError for very large or very small values.
* gh-111417: Remove unused code block in math.trunc() and round() (GH-111454)Jason Zhang2024-02-031-5/+0
| | | _PyObject_LookupSpecial() now ensures that the type is ready.
* gh-90350: Optimize builtin functions min() and max() (GH-30286)colorfulappl2023-12-111-36/+45
| | | | Builtin functions min() and max() now use METH_FASTCALL
* gh-74616: Raise ValueError in case of null character in input prompt (GH-1738)Kushal Das2023-12-071-0/+5
| | | | | | | If the input prompt to the builtin input function on terminal has any null character, then raise ValueError instead of silently truncating it. Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

* gh-110014: Include explicitly <unistd.h> header (#110155)Victor Stinner2023-09-301-0/+5
| | | | | | | | | | | * Remove unused <locale.h> includes. * Remove unused <fcntl.h> include in traceback.h. * Remove redundant <assert.h> and <stddef.h> includes. They are already included by "Python.h". * Remove <object.h> include in faulthandler.c. Python.h already includes it. * Add missing <stdbool.h> in pycore_pythread.h if HAVE_PTHREAD_STUBS is defined. * Fix also warnings in pthread_stubs.h: don't redefine macros if they are already defined, like the __NEED_pthread_t macro.
* gh-109611: Add convenient C API function _PyFile_Flush() (GH-109612)Serhiy Storchaka2023-09-231-15/+7
|
* gh-108765: Python.h no longer includes <ctype.h> (#108831)Victor Stinner2023-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | Remove <ctype.h> in C files which don't use it; only sre.c and _decimal.c still use it. Remove _PY_PORT_CTYPE_UTF8_ISSUE code from pyport.h: * Code added by commit b5047fd01948ab108edcc1b3c2c901d915814cfd in 2004 for MacOSX and FreeBSD. * Test removed by commit 52ddaefb6bab1a74ecffe8519c02735794ebfbe1 in 2007, since Python str type now uses locale independent functions like Py_ISALPHA() and Py_TOLOWER() and the Unicode database. Modules/_sre/sre.c replaces _PY_PORT_CTYPE_UTF8_ISSUE with new functions: sre_isalnum(), sre_tolower(), sre_toupper(). Remove unused includes: * _localemodule.c: remove <stdio.h>. * getargs.c: remove <float.h>. * dynload_win.c: remove <direct.h>, it no longer calls _getcwd() since commit fb1f68ed7cc1536482d1debd70a53c5442135fe2 (in 2001).
* gh-108634: Py_TRACE_REFS uses a hash table (#108663)Victor Stinner2023-08-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Python built with "configure --with-trace-refs" (tracing references) is now ABI compatible with Python release build and debug build. Moreover, it now also supports the Limited API. Change Py_TRACE_REFS build: * Remove _PyObject_EXTRA_INIT macro. * The PyObject structure no longer has two extra members (_ob_prev and _ob_next). * Use a hash table (_Py_hashtable_t) to trace references (all objects): PyInterpreterState.object_state.refchain. * Py_TRACE_REFS build is now ABI compatible with release build and debug build. * Limited C API extensions can now be built with Py_TRACE_REFS: xxlimited, xxlimited_35, _testclinic_limited. * No longer rename PyModule_Create2() and PyModule_FromDefAndSpec2() functions to PyModule_Create2TraceRefs() and PyModule_FromDefAndSpec2TraceRefs(). * _Py_PrintReferenceAddresses() is now called before finalize_interp_delete() which deletes the refchain hash table. * test_tracemalloc find_trace() now also filters by size to ignore the memory allocated by _PyRefchain_Trace(). Test changes for Py_TRACE_REFS: * Add test.support.Py_TRACE_REFS constant. * Add test_sys.test_getobjects() to test sys.getobjects() function. * test_exceptions skips test_recursion_normalizing_with_no_memory() and test_memory_error_in_PyErr_PrintEx() if Python is built with Py_TRACE_REFS. * test_repl skips test_no_memory(). * test_capi skisp test_set_nomemory().
* gh-106320: Remove private pythonrun API (#108599)Victor Stinner2023-08-291-0/+1
| | | | | | | | | | | Remove these private functions from the public C API: * _PyRun_AnyFileObject() * _PyRun_InteractiveLoopObject() * _PyRun_SimpleFileObject() * _Py_SourceAsString() Move them to the internal C API: add a new pycore_pythonrun.h header file. No longer export these functions.
* gh-106320: Remove private _PySys functions (#108452)Victor Stinner2023-08-241-0/+1
| | | | | | | | | | Move private functions to the internal C API (pycore_sysmodule.h): * _PySys_GetAttr() * _PySys_GetSizeOf() No longer export most of these functions. Fix also a typo in Include/cpython/optimizer.h: add a missing space.

* gh-106572: Convert PyObject_DelAttr() to a function (#106611)Victor Stinner2023-07-111-1/+2
| | | | | | | | * Convert PyObject_DelAttr() and PyObject_DelAttrString() macros to functions. * Add PyObject_DelAttr() and PyObject_DelAttrString() functions to the stable ABI. * Replace PyObject_SetAttr(obj, name, NULL) with PyObject_DelAttr(obj, name).
* gh-105340: include hidden fast-locals in locals() (#105715)Carl Meyer2023-07-051-34/+53

* gh-106320: Create pycore_modsupport.h header file (#106355)Victor Stinner2023-07-031-1/+2
| | | | | | | | | | Remove the following functions from the C API, move them to the internal C API: add a new pycore_modsupport.h internal header file: * PyModule_CreateInitialized() * _PyArg_NoKwnames() * _Py_VaBuildStack() No longer export these functions.

* gh-94673: Ensure Builtin Static Types are Readied Properly (gh-103940)Eric Snow2023-04-271-1/+1
| | | There were cases where we do unnecessary work for builtin static types. This also simplifies some work necessary for a per-interpreter GIL.
* gh-102939: Fix "conversion from Py_ssize_t to long" warning in builtins ↵Nikita Sobolev2023-03-231-2/+2

* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-8/+8
| | | | | | | | | | * Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts. * Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints. * Add functions to hide some internals of long object, and for setting sign and digit count. * Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().
* gh-102660: Fix Refleaks in import.c (#102744)Eric Snow2023-03-161-3/+0
| | | | | gh-102661 introduced some leaks. This fixes them. https://github.com/python/cpython/issues/102660
* gh-102660: Handle m_copy Specially for the sys and builtins Modules (gh-102661)Eric Snow2023-03-141-0/+3
| | | | | | | It doesn't make sense to use multi-phase init for these modules. Using a per-interpreter "m_copy" (instead of PyModuleDef.m_base.m_copy) makes this work okay. (This came up while working on gh-101660.) Note that we might instead end up disallowing re-load for sys/builtins since they are so special. https://github.com/python/cpython/issues/102660
* gh-102356: Add thrashcan macros to filter object dealloc (#102426)Marta Gómez Macías2023-03-051-0/+2

* bpo-15999: Accept arbitrary values for boolean parameters. (#15609)Serhiy Storchaka2022-12-031-2/+2
| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* gh-99537: Use Py_SETREF(var, NULL) in C code (#99687)Victor Stinner2022-11-231-8/+4
| | | Replace "Py_DECREF(var); var = NULL;" with "Py_SETREF(var, NULL);".
