| * Issue #3329: Implement the PEP 445Victor Stinner2013-07-071-0/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new enum: * PyMemAllocatorDomain Add new structures: * PyMemAllocator * PyObjectArenaAllocator Add new functions: * PyMem_RawMalloc(), PyMem_RawRealloc(), PyMem_RawFree() * PyMem_GetAllocator(), PyMem_SetAllocator() * PyObject_GetArenaAllocator(), PyObject_SetArenaAllocator() * PyMem_SetupDebugHooks() Changes: * PyMem_Malloc()/PyObject_Realloc() now always call malloc()/realloc(), instead of calling PyObject_Malloc()/PyObject_Realloc() in debug mode. * PyObject_Malloc()/PyObject_Realloc() now falls back to PyMem_Malloc()/PyMem_Realloc() for allocations larger than 512 bytes. * Redesign debug checks on memory block allocators as hooks, instead of using C macros

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Clarified comment on the impact of BLOCKLEN on deque_index (with a power-of-two, the division and modulo computations are done with a right-shift and bitwise-and). * Clarified comment on the overflow check to note that it is general and not just applicable the 64-bit builds. * In deque._rotate(), the "deque->" indirections are factored-out of the loop (loop invariant code motion), leaving the code cleaner looking and slightly faster. * In deque._rotate(), replaced the memcpy() with an equivalent loop. That saved the memcpy setup time and allowed the pointers to move in their natural leftward and rightward directions. See comparative timings at: http://pastebin.com/p0RJnT5N
