From 892dbb41bc633cdeded2446eabe6c72adbd44bd2 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Tue, 12 May 2020 02:22:00 +0200 Subject: [PATCH] bpo-40602: _Py_hashtable_new() uses PyMem_Malloc() _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(-) diff --git a/Python/hashtable.c b/Python/hashtable.c index 22b84590105f9e..e9f02d8650e4f8 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) pFad - Phonifier reborn
