From d0919f0d6bb757b6bcfd7b2e15656d318c9d5cd9 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Tue, 12 May 2020 03:07:40 +0200 Subject: bpo-40602: _Py_hashtable_new() uses PyMem_Malloc() (GH-20046) _Py_hashtable_new() now uses PyMem_Malloc/PyMem_Free allocator by default, rather than PyMem_RawMalloc/PyMem_RawFree. PyMem_Malloc is faster than PyMem_RawMalloc for memory blocks smaller than or equal to 512 bytes. --- Python/hashtable.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'Python/hashtable.c') diff --git a/Python/hashtable.c b/Python/hashtable.c index 22b8459010..e9f02d8650 100644 --- a/Python/hashtable.c +++ b/Python/hashtable.c @@ -149,11 +149,12 @@ _Py_hashtable_new_full(size_t key_size, size_t data_size, _Py_hashtable_allocator_t alloc; if (allocator == NULL) { - alloc.malloc = PyMem_RawMalloc; - alloc.free = PyMem_RawFree; + alloc.malloc = PyMem_Malloc; + alloc.free = PyMem_Free; } - else + else { alloc = *allocator; + } ht = (_Py_hashtable_t *)alloc.malloc(sizeof(_Py_hashtable_t)); if (ht == NULL) -- cgit v1.2.1
