Serhiy Storchaka 1ed017ae92 Issue #20440: Cleaning up the code by using Py_SETREF and Py_CLEAR.
Old code is correct, but with Py_SETREF and Py_CLEAR it can be cleaner.
This patch doesn't fix bugs and hence there is no need to backport it.

Serhiy Storchaka a9406e77fa Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size.
This allows sys.getsize() to work correctly with their subclasses with
__slots__ defined.

Raymond Hettinger daf57f25e5 Bump the blocksize up from 62 to 64 to speed up the modulo calculation.
Remove the old comment suggesting that it was desireable to have
blocksize+2 as a multiple of the cache line length.  That would
have made sense only if the block structure start point was always
aligned to a cache line boundary.  However, the memory allocations
are 16 byte aligned, so we don't really have control over whether
the struct spills across cache line boundaries.

2013-10-01 00:55:43 -07:00
Raymond Hettinger 77578204d6 Restore the data block size to 62.
The former block size traded away good fit within cache lines in
order to gain faster division in deque_item().  However, compilers
are getting smarter and can now replace the slow division operation
with a fast integer multiply and right shift.  Accordingly, it makes
sense to go back to a size that lets blocks neatly fill entire
cache-lines.

GCC-4.8 and CLANG 4.0 both compute "x // 62" with something
roughly equivalent to "x * 9520900167075897609 >> 69".

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
2013-07-05 18:05:29 -10:00
Raymond Hettinger 20b0f87e1d Misc improvements to collections.deque()
* Clarified comment on the impact of BLOCKLEN on deque_index
  (with a power-of-two, the division and modulo
   computations are done with a right-shift and bitwise-and).

* Clarified comment on the overflow check to note that
  it is general and not just applicable the 64-bit builds.

* In deque._rotate(), the "deque->" indirections are
  factored-out of the loop (loop invariant code motion),
  leaving the code cleaner looking and slightly faster.

* In deque._rotate(), replaced the memcpy() with an
  equivalent loop.  That saved the memcpy setup time
  and allowed the pointers to move in their natural
  leftward and rightward directions.

Amaury Forgeot d'Arc f43ee81ef2 #4170: Fix segfault when pickling a defauldict object.
The 2.x dict.iteritems() returns an iterator,
whereas the 3.0 dict.items() returns a "view",
which is iterable, but not an iterator with its __next__ method.

Patch by Hirokazu Yamamoto.

  #3743: PY_FORMAT_SIZE_T is designed for the OS "printf" functions, not for
  PyString_FromFormat which has an independent implementation, and uses "%zd".

  This makes a difference on win64, where printf needs "%Id" to display
  64bit values. For example, queue.__repr__ was incorrect.
