bpo-41078: Rename pycore_tupleobject.h to pycore_tuple.h (GH-21056)
2020-06-22 15:27:35 +00:00
#ifndef Py_INTERNAL_TUPLE_H
#define Py_INTERNAL_TUPLE_H
bpo-35081: Add Include/internal/pycore_tupleobject.h (GH-10705) Move _PyTuple_ITEMS() to a new header file: Include/internal/pycore_tupleobject.h
2018-11-25 22:56:17 +00:00
#ifdef __cplusplus
extern "C" {
#endif
bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853) Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros of pyport.h when Py_BUILD_CORE_MODULE is defined. The Py_BUILD_CORE_MODULE define must be now be used to build a C extension as a dynamic library accessing Python internals: export the PyInit_xxx() function in DLL exports on Windows. Changes: * Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply Py_BUILD_CORE directy in pyport.h. * ceval.c compilation now fails with an error if Py_BUILD_CORE is not defined, just to ensure that Python is build with the correct defines. * setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define. * setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather than Py_BUILD_CORE_BUILTIN define * PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.

bpo-46008: Make runtime-global object/type lifecycle functions and state 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
