From 5c75f37d473140f0e0b7d9bf3a8c08343447ded1 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Wed, 17 Apr 2019 23:02:26 +0200 Subject: 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. --- Python/ceval.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'Python') diff --git a/Python/ceval.c b/Python/ceval.c index 28e923219d..342dc10af6 100644 --- a/Python/ceval.c +++ b/Python/ceval.c @@ -30,6 +30,10 @@ #define CHECKEXC 1 /* Double-check exception checking */ #endif +#if !defined(Py_BUILD_CORE) +# error "ceval.c must be build with Py_BUILD_CORE define for best performance" +#endif + /* Private API for the LOAD_METHOD opcode. */ extern int _PyObject_GetMethod(PyObject *, PyObject *, PyObject **); -- cgit v1.2.1
