[issue16398] deque.rotate() could be much faster

Simon Law added the comment: Raymond, looking at your patch, can we assert that deque-leftblock is never equal to deque-rightblock? If not, you need to use memmove() instead of memcpy(), which is unsafe for overlapping arrays. It is not clear to me that this invariant is true. At the very

[issue16395] Documentation claims that PySequence_Fast returns a tuple, when it actually returns a list.

New submission from Simon Law: The documentation in Python 2.7, 3.2, and 3.3 claim that: PyObject* PySequence_Fast(PyObject *o, const char *m) Return value: New reference. Returns the sequence o as a tuple, unless it is already a tuple or list, in which case o is returned... Unfortunately

Simon Law added the comment: 15125-2.patch applies to the default branch. It makes dest behave the same for positional and optional arguments in terms of name mangling. Also, there is a backward-compatibility path in Namespace to support old-style getattr() access. However, it's

[issue16398] deque.rotate() could be much faster

New submission from Simon Law: If you look at the implementation of deque.rotate(), it does the equivalent of deque.append(deque.popleft()) or deque.appendleft(deque.pop()). Unfortunately, for larger rotations, the pop() and append() calls just do too much work. Since the documentation
