* Issue #18874: _PyObject_Malloc/Realloc/Free() now falls back onVictor Stinner2013-10-101-17/+19
| | | | | | _PyMem_RawMalloc/Realloc/Free, instead of _PyMem_Malloc/Realloc/Free. So it becomes possible to use the fast pymalloc allocator for the PYMEM_DOMAIN_MEM domain (PyMem_Malloc/Realloc/Free functions).

* Issue #19171: speed some cases of 3-argument long pow().Tim Peters2013-10-051-4/+10
|\ | | | | | | | | | | | | | | | | | | Reduce the base by the modulus when the base is larger than the modulus. This can unboundedly speed the "startup costs" of doing modular exponentiation, particularly in cases where the base is much larger than the modulus. Original patch by Armin Rigo, inspired by https://github.com/pyca/ed25519. Merged from 3.3.

* | Remove the freelist scheme for setobjects.Raymond Hettinger2013-09-082-48/+8
| | | | | | | | | | | | | | | | | | The setobject freelist was consuming memory but not providing much value. Even when a freelisted setobject was available, most of the setobject fields still needed to be initialized and the small table still required a memset(). This meant that the custom freelisting scheme for sets was providing almost no incremental benefit over the default Python freelist scheme used by _PyObject_Malloc() in Objects/obmalloc.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | addressing. Modern processors tend to make consecutive memory accesses cheaper than random probes into memory. Small sets can fit into L1 cache, so they get less benefit. But they do come out ahead because the consecutive probes don't probe the same key more than once and because the randomization step occurs less frequently (or not at all). For the open addressing step, putting the perturb shift before the index calculation gets the upper bits into play sooner.
