Raymond Hettinger 3743432302 Issue #26194: Fix undefined behavior for deque.insert() when len(d) == maxlen 2016-01-26 21:44:16 -08:00
Raymond Hettinger 306d6b1ea6 Convert another post-decrement while-loop to pre-decrement for consistency
and better generated code (on both GCC and CLang).

Raymond Hettinger d84ec225bd Miscellaneous refactorings
* Add comment to the maxlen structure entry about the meaning of maxlen == -1
* Factor-out code common to deque_append(left) and deque_extend(left)
* Factor inner-loop in deque_clear() to use only 1 test per loop instead of 2
* Tighten inner-loops for deque_item() and deque_ass_item() so that the
  compiler can combine the decrement and test into a single step.

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.
