* bpo-38896: Remove PyUnicode_ClearFreeList() function (GH-17354)Victor Stinner2019-11-231-0/+2
| | | | Remove PyUnicode_ClearFreeList() function: the Unicode free list has been removed in Python 3.3.
* bpo-37340: Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() ↵Victor Stinner2019-11-201-0/+2
| | | | | | | | (GH-17284) Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() functions: the free lists of bound method objects have been removed. Remove also _PyMethod_Fini() and _PyCFunction_Fini() functions.
* bpo-38835: Exclude PyFPE macros from the stable API (GH-17228)Victor Stinner2019-11-201-0/+2

* bpo-37645: add new function _PyObject_FunctionStr() (GH-14890)Jeroen Demeyer2019-11-051-0/+2
| | | | | | | | | | | | Additional note: the `method_check_args` function in `Objects/descrobject.c` is written in such a way that it applies to all kinds of descriptors. In particular, a future re-implementation of `wrapper_descriptor` could use that code. CC @vstinner @encukou https://bugs.python.org/issue37645 Automerge-Triggered-By: @encukou
* bpo-35381 Remove all static state from posixmodule (GH-15892)Eddie Elizondo2019-11-051-0/+2
| | | | | | | | | | | | | | After #9665, this moves the remaining types in posixmodule to be heap-allocated to make it compatible with PEP384 as well as modifying all the type accessors to fully make the type opaque. The original PR that got messed up a rebase: https://github.com/python/cpython/pull/10854. All the issues in that commit have now been addressed since https://github.com/python/cpython/pull/11661 got committed. This change also removes any state from the data segment and onto the module state itself. https://bugs.python.org/issue35381 Automerge-Triggered-By: @encukou
* closes bpo-37633: Reëxport some function compatibility wrappers for macros ↵Benjamin Peterson2019-11-051-0/+1

* bpo-38644: Add Py_EnterRecursiveCall() to the limited API (GH-17046)Victor Stinner2019-11-041-0/+5
| | | | | | | | | | Provide Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() as regular functions for the limited API. Previously, there were defined as macros, but these macros didn't work with the limited API which cannot access PyThreadState.recursion_depth field. Remove _Py_CheckRecursionLimit from the stable ABI. Add Include/cpython/ceval.h header file.

* bpo-38395: Fix ownership in weakref.proxy methods (GH-16632)Pablo Galindo2019-10-081-0/+3
| | | | | | | | | | | | | The implementation of weakref.proxy's methods call back into the Python API using a borrowed references of the weakly referenced object (acquired via PyWeakref_GET_OBJECT). This API call may delete the last reference to the object (either directly or via GC), leaving a dangling pointer, which can be subsequently dereferenced. To fix this, claim a temporary ownership of the referenced object when calling the appropriate method. Some functions because at the moment they do not need to access the borrowed referent, but to protect against future changes to these functions, ownership need to be fixed in all potentially affected methods.
* bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)Victor Stinner2019-10-071-0/+3
| | | | | | | | | | | | | | | | | | | | | bpo-36389, bpo-38376: The _PyObject_CheckConsistency() function is now also available in release mode. For example, it can be used to debug a crash in the visit_decref() function of the GC. Modify the following functions to also work in release mode: * _PyDict_CheckConsistency() * _PyObject_CheckConsistency() * _PyType_CheckConsistency() * _PyUnicode_CheckConsistency() Other changes: * _PyMem_IsPtrFreed(ptr) now also returns 1 if ptr is NULL (equals to 0). * _PyBytesWriter_CheckConsistency() now returns 1 and is only used with assert(). * Reorder _PyObject_Dump() to write safe fields first, and only attempt to render repr() at the end.
* bpo-38266: Revert bpo-37878: Make PyThreadState_DeleteCurrent() Internal ↵Joannah Nanjekye2019-10-041-0/+1
| | | | | (GH-16558) Revert the removal of PyThreadState_DeleteCurrent() with documentation.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-011-3/+0
| | | | | | | For now, we'll rely on the fact that the config structures aren't covered by the stable ABI. We may revisit this in the future if we further explore the idea of offering a stable embedding API. (cherry picked from commit bdace21b769998396d0ccc8da99a8ca9b507bfdf)
* bpo-38304: Add PyConfig.struct_size (GH-16451)Victor Stinner2019-09-281-0/+3
| | | | | | | | | | | | | | | | | Add a new struct_size field to PyPreConfig and PyConfig structures to allow to modify these structures in the future without breaking the backward compatibility. * Replace private _config_version field with public struct_size field in PyPreConfig and PyConfig. * Public PyPreConfig_InitIsolatedConfig() and PyPreConfig_InitPythonConfig() return type becomes PyStatus, instead of void. * Internal _PyConfig_InitCompatConfig(), _PyPreConfig_InitCompatConfig(), _PyPreConfig_InitFromConfig(), _PyPreConfig_InitFromPreConfig() return type becomes PyStatus, instead of void. * Remove _Py_CONFIG_VERSION * Update the Initialization Configuration documentation.
* bpo-38234: Py_SetPath() uses the program full path (GH-16357)Victor Stinner2019-09-241-0/+3
| | | | | | | Py_SetPath() now sets sys.executable to the program full path (Py_GetProgramFullPath()), rather than to the program name (Py_GetProgramName()). Fix also memory leaks in pathconfig_set_from_config().
* bpo-38234: Fix _PyConfig_InitPathConfig() (GH-16335)Victor Stinner2019-09-231-2/+3
| | | | | | | | | | | | | | | | * _PyConfig_InitPathConfig() now starts by copying the global path configuration, and then override values set in PyConfig. * _PyPathConfig_Calculate() implementations no longer override _PyPathConfig fields which are already computed. For example, if _PyPathConfig.prefix is not NULL, leave it unchanged. * If Py_SetPath() has been called, _PyConfig_InitPathConfig() doesn't call _PyPathConfig_Calculate() anymore. * _PyPathConfig_Calculate() no longer uses PyConfig, except to initialize PyCalculatePath structure. * pathconfig_calculate(): remove useless temporary "_PyPathConfig new_config" variable. * calculate_module_search_path(): remove hack to workaround memory allocation failure, call Py_FatalError() instead. * Fix get_program_full_path(): handle memory allocation failure.
* bpo-38234: Fix PyConfig_Read() when Py_SetPath() was called (GH-16298)Victor Stinner2019-09-201-0/+2
| | | | | | * If Py_SetPath() has been called, _PyConfig_InitPathConfig() now uses its value. * Py_Initialize() now longer copies path configuration from PyConfig to the global path configuration (_Py_path_config).
* bpo-38205: Py_UNREACHABLE() calls Py_FatalError() (GH-16290)Victor Stinner2019-09-201-0/+1

* bpo-21120: Exclude Python-ast.h, ast.h and asdl.h from the limited API (#14634)Zackery Spytz2019-09-121-0/+1
| | | | The PyArena type is not part of the limited API, so these headers shouldn't be part of it either.

* bpo-37151: remove special case for PyCFunction from PyObject_Call (GH-14684)Jeroen Demeyer2019-09-111-0/+1
| | | | | | | bpo-37151: remove special case for PyCFunction from PyObject_Call Alse, make the undocumented function PyCFunction_Call an alias of PyObject_Call and deprecate it.
* bpo-37879: Suppress subtype_dealloc decref when base type is a C heap type ↵Eddie Elizondo2019-09-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-15323) The instance destructor for a type is responsible for preparing an instance for deallocation by decrementing the reference counts of its referents. If an instance belongs to a heap type, the type object of an instance has its reference count decremented while for static types, which are permanently allocated, the type object is unaffected by the instance destructor. Previously, the default instance destructor searched the class hierarchy for an inherited instance destructor and, if present, would invoke it. Then, if the instance type is a heap type, it would decrement the reference count of that heap type. However, this could result in the premature destruction of a type because the inherited instance destructor should have already decremented the reference count of the type object. This change avoids the premature destruction of the type object by suppressing the decrement of its reference count when an inherited, non-default instance destructor has been invoked. Finally, an assertion on the Py_SIZE of a type was deleted. Heap types have a non zero size, making this into an incorrect assertion. https://github.com/python/cpython/pull/15323
* bpo-15088 : Remove PyGen_NeedsFinalizing() (GH-15702)Joannah Nanjekye2019-09-061-0/+4
| | | | | Remove PyGen_NeedsFinalizing(): it was not documented, tested or used anywhere within CPython after the implementation of PEP 442.
* bpo-36763: PyConfig_Read() handles PySys_AddXOption() (GH-15431)Victor Stinner2019-08-231-0/+2
| | | | | | | | | | PyConfig_Read() is now responsible to handle early calls to PySys_AddXOption() and PySys_AddWarnOption(). Options added by PySys_AddXOption() are now handled the same way than PyConfig.xoptions and command line -X options. For example, PySys_AddXOption(L"faulthandler") enables faulthandler as expected.
* bpo-37926: Fix PySys_SetArgvEx(0, NULL, 0) crash (GH-15415)Victor Stinner2019-08-231-0/+1
| | | | | | | | | | empty_argv is no longer static in Python 3.8, but it is declared in a temporary scope, whereas argv keeps a reference to it. empty_argv memory (allocated on the stack) is reused by make_sys_argv() code which is inlined when using gcc -O3. Define empty_argv in PySys_SetArgvEx() body, to ensure that it remains valid for the whole lifetime of the PySys_SetArgvEx() call.
* bpo-37540: vectorcall: keyword names must be strings (GH-14682)Jeroen Demeyer2019-08-161-0/+2
| | | | | | | | The fact that keyword names are strings is now part of the vectorcall and `METH_FASTCALL` protocols. The biggest concrete change is that `_PyStack_UnpackDict` now checks that and raises `TypeError` if not. CC @markshannon @vstinner https://bugs.python.org/issue37540
* bpo-37207: enable vectorcall for type.__call__ (GH-14588)Jeroen Demeyer2019-08-151-0/+3

* bpo-37194: Add a new public PyObject_CallNoArgs() function (GH-13890)Victor Stinner2019-06-171-0/+6
| | | | | | | | | | | | | | | Add a new public PyObject_CallNoArgs() function to the C API: call a callable Python object without any arguments. It is the most efficient way to call a callback without any argument. On x86-64, for example, PyObject_CallFunctionObjArgs(func, NULL) allocates 960 bytes on the stack per call, whereas PyObject_CallNoArgs(func) only allocates 624 bytes per call. It is excluded from stable ABI 3.8. Replace private _PyObject_CallNoArg() with public PyObject_CallNoArgs() in C extensions: _asyncio, _datetime, _elementtree, _pickle, _tkinter and readline.
