Victor Stinner 4202456cd4 Issue #18408: _pickle.c: Add missing PyErr_NoMemory() on memory allocation failures 2013-07-12 00:53:57 +02:00
Victor Stinner 8ca72e2e3d Issue #18408: _PyMemoTable_ResizeTable() now restores the old table if 
allocating a bigger table failed

PyMemoTable destructor does crash if mt_table is NULL.

Victor Stinner c31df04234 Issue #18408: Oh, I was wrong: Pickler_New() must call Py_DECREF() to destroy 
the newly created pickler, and not PyObject_GC_Del().

Victor Stinner 71c8b7ec04 Issue #18408: Different fixes in _elementtree.c to handle correctly MemoryError 
* create_new_element() initializes all attributes before handling errors,
   to fix a crash in the destructor
* create_new_element() calls PyObject_GC_Del() on error, instead of
  PyObject_Del(), because the object was created by PyObject_GC_New()
* subelement() now handles create_new_element() failure
* element_getattro() now handles element_get_text() failure
* makeuniversal() now handles PyBytes_FromStringAndSize() failure

Victor Stinner 68c8ea25f1 Issue #18408: Fix _Pickler_New() and _Unpickler_New(): initialize all 
attributes before handling errors

_Pickler_New() now calls PyObject_GC_Del() instead of Py_DECREF() on error,
because the pickle object is created using PyObject_GC_New().

Fix a crash in the destructor when an attribute is not initiallized.

Victor Stinner 7979926616 Issue #18408: Fix usage of _PyBytes_Resize() 
_PyBytes_Resize(&v, new_size) sets v to NULL on error, so v cannot be used
anymore. Replace "Py_DECREF(v); v = NULL;" with "Py_CLEAR(v);".

* Replace malloc() with PyMem_RawMalloc()

Raymond Hettinger 82df925451 Use macros for marking and checking endpoints in the doubly-linked list of blocks. 
* Add comment explaining the endpoint checks
* Only do the checks in a debug build
* Simplify newblock() to only require a length argument
  and leave the link updates to the calling code.
* Also add comment for the freelisting logic.

Victor Stinner 0507bf56f0 Issue #3329: Implement the PEP 445 
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

Raymond Hettinger de68e0cf0e Speed-up deque indexing by changing the deque block length to a power of two. 
The division and modulo calculation in deque_item() can be compiled
to fast bitwise operations when the BLOCKLEN is a power of two.

Timing before:

 ~/cpython $ py -m timeit -r7 -s 'from collections import deque' -s 'd=deque(range(10))' 'd[5]'
10000000 loops, best of 7: 0.0627 usec per loop

Timing after:

~/cpython $ py -m timeit -r7 -s 'from collections import deque' -s 'd=deque(range(10))' 'd[5]'
10000000 loops, best of 7: 0.0581 usec per loop

Victor Stinner 93037498d1 Fix time.mktime() and datetime.datetime.timestamp() on AIX 
On AIX, the C function mktime() alwaysd sets tm_wday, even on error. So tm_wday
cannot be used as a sentinel to detect an error, we can only check if the
result is (time_t)-1.
