New submission from Jukka Laurila <[EMAIL PROTECTED]>: Currently Python always uses the C library malloc/realloc/free as the underlying mechanism for requesting memory from the OS, but especially on memory-limited platforms it is often desirable to be able to override the allocator and to redirect all Python's allocations to use a special heap. This will make it possible to free memory back to the operating system without restarting the process, and to reduce fragmentation by separating Python's allocations from the rest of the program.
The proposal is to make it possible to set the allocator used by the Python interpreter by calling the following function before Py_Initialize(): void Py_SetAllocator(void* (*alloc)(size_t), void* (*realloc)(void*, size_t), void (*free)(void*)) Direct function calls to malloc/realloc/free in obmalloc.c must be replaced with calls through the function pointers set through this function. By default these would of course point to the C stdlib malloc/realloc/free. ---------- components: Interpreter Core messages: 69482 nosy: jlaurila severity: normal status: open title: API for setting the memory allocator used by Python type: feature request versions: Python 2.6, Python 3.0 _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3329> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
