[Python-Dev] Breaking builds (original) (raw)

I may or may not have just broken one or more parts of the build for non-Windows boxes. Please check it out, especially on Linux.

What changed: As spelled out before, as part of enabling pymalloc we need to redirect PyMem_{DEL, Del} to the pymalloc free(), for backward compatibility of old extension modules.

This creates an internal problem because the parser stuff uses these guys, but has never included Python.h, and can't "see" the declarations of the PyObject_XYZ functions in objimpl.h. Instead, pgenheaders.h has been growing its own maze of includes and defines. I scrapped all that, and had it include Python.h instead, like everything else does.

This all works on Windows, but Windows is Special . I at least expect that using pgen to rebuild the grammar files will need to link in obmalloc.o on Linux.

Other changes: When PYMALLOC_DEBUG is defined (it is by default in a debug build), all PyMem_XYZ functions funnel thru the debugging allocator now. So we get debugging decorations on all allocations then, except for direct calls to platform malloc/realloc/free. Note that platform malloc/realloc/free cannot be mixed with PyMem_XYZ! compile.c actually did that once, and it broke (it's fixed).
