Update of /cvsroot/python/python/dist/src/Include
In directory usw-pr-cvs1:/tmp/cvs-serv12203/Include
Modified Files:
objimpl.h
Log Message:
Remove PyMalloc_* symbols. PyObject_Malloc now uses pymalloc if
it's enabled. To avoid breaking extension modules that allocate using
PyObject_{NEW,New} and deallocate with PyMem_{Del,DEL}, PyMem_DEL has
been changed to call pymalloc's free.
Allow PyObject_Del, PyObject_Free, and PyObject_GC_Del to be used as
function designators. Provide source compatibility macros.
Make PyObject_GC_Track and PyObject_GC_UnTrack functions instead of
trivial macros wrapping functions.
