* gh-103906: Remove immortal refcounting in compile/marshal.c (gh-103922)Dong-hee Na2023-06-051-1/+1
|
* gh-84436: Implement Immortal Objects (gh-19474)Eddie Elizondo2023-04-221-2/+13
| | | | | | | | | This is the implementation of PEP683 Motivation: The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime. Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.
* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-3/+3
| | | | | | | | | | * 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-84783: Make the slice object hashable (GH-101264)Furkan Onder2023-02-191-1/+37

* gh-99537: Use Py_SETREF() function in C code (#99657)Victor Stinner2022-11-221-16/+6
| | | | | | | | | | | | | | | Fix potential race condition in code patterns: * Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);" * Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);" * Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);" Other changes: * Replace "old = var; var = new; Py_DECREF(var)" with "Py_SETREF(var, new);" * Replace "old = var; var = new; Py_XDECREF(var)" with "Py_XSETREF(var, new);" * And remove the "old" variable.
* gh-99300: Use Py_NewRef() in Objects/ directory (#99354)Victor Stinner2022-11-101-17/+9
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in C files of the Objects/ directory.
* GH-94163: Add BINARY_SLICE and STORE_SLICE instructions. (GH-94168)Mark Shannon2022-06-271-17/+34
|
* gh-91731: Replace Py_BUILD_ASSERT() with static_assert() (#91730)Victor Stinner2022-04-201-1/+2
| | | | | | | | | | | | Python 3.11 now uses C11 standard which adds static_assert() to <assert.h>. * In pytime.c, replace Py_BUILD_ASSERT() with preprocessor checks on SIZEOF_TIME_T with #error. * On macOS, py_mach_timebase_info() now accepts timebase members with the same size than _PyTime_t. * py_get_monotonic_clock() now saturates GetTickCount64() to _PyTime_MAX: GetTickCount64() is unsigned, whereas _PyTime_t is signed.
* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-2/+1
| | | | | | | | | | | | | | | 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-42161: Use _PyLong_GetZero() and _PyLong_GetOne() (GH-22995)Victor Stinner2020-10-271-2/+3
| | | | Use _PyLong_GetZero() and _PyLong_GetOne() in Objects/ and Python/ directories.
* bpo-40521: Cleanup code of free lists (GH-21082)Victor Stinner2020-06-231-8/+16
| | | Add get_xxx_state() function to factorize duplicated code.
* bpo-40521: Make slice cache per-interpreter (GH-20637)Victor Stinner2020-06-041-14/+15
| | | | | | Each interpreter now has its own slice cache: * Move slice cache into PyInterpreterState. * Add tstate parameter to _PySlice_Fini().
* bpo-40268: Remove unused pycore_pymem.h includes (GH-19531)Victor Stinner2020-04-151-1/+0
|
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-2/+2
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-1/+0
|
* bpo-40170: Add _PyIndex_Check() internal function (GH-19426)Victor Stinner2020-04-081-1/+2
| | | | | | | | | Add _PyIndex_Check() function to the internal C API: fast inlined verson of PyIndex_Check(). Add Include/internal/pycore_abstract.h header file. Replace PyIndex_Check() with _PyIndex_Check() in C files of Objects and Python subdirectories.
* Make PyXXX_Fini() functions private (GH-15531)Victor Stinner2019-08-261-1/+2
| | | | | For example, rename PyTuple_Fini() to _PyTuple_Fini(). These functions are only declared in the internal C API.
* bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async ↵Jeroen Demeyer2019-05-311-4/+4
| | | | | | | | | (GH-13464) Automatically replace tp_print -> tp_vectorcall_offset tp_compare -> tp_as_async tp_reserved -> tp_as_async
* bpo-35961: Fix a crash in slice_richcompare() (GH-11830)Victor Stinner2019-02-131-24/+14
| | | | | | | | Fix a crash in slice_richcompare(): use strong references rather than stolen references for the two temporary internal tuples. The crash (or assertion error) occurred if a garbage collection occurred during slice_richcompare(), especially while calling PyObject_RichCompare(t1, t2, op).
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-211-0/+1
| | | | 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 Stinner2018-11-121-2/+2
| | | | | | | | | | | | | | 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 pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-2/+2
| | | | | | | | | | | | | | | | | | | | * 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-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-3/+3
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-0/+2
| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).
* bpo-30592: Fixed error messages for some builtins. (#1996)Serhiy Storchaka2017-06-081-1/+1
| | | | | Error messages when pass keyword arguments to some builtins that don't support keyword arguments contained double parenthesis: "()()". The regression was introduced by bpo-30534.
