* bpo-40636: Clarify the zip built-in docstring. (GH-20118)Miss Islington (bot)2020-05-151-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | Clarify the zip built-in docstring. This puts much simpler text up front along with an example. As it was, the zip built-in docstring was technically correct. But too technical for the reader who shouldn't _need_ to know about `__next__` and `StopIteration` as most people do not need to understand the internal implementation details of the iterator protocol in their daily life. This is a documentation only change, intended to be backported to 3.8; it is only tangentially related to PEP-618 which might offer new behavior options in the future. Wording based a bit more on enumerate per Brandt's suggestion. This gets rid of the legacy wording paragraph which seems too tied to implementation details of the iterator protocol which isn't relevant here.

* bpo-39847: EnterNonRecursiveMutex() uses GetTickCount64() (GH-18780)Miss Islington (bot)2020-03-111-3/+3
| | | | | | | | | | | | | | | | | | The 32-bit (49-day) TickCount relied on in EnterNonRecursiveMutex can overflow in the gap between the 'target' time and the 'now' time WaitForSingleObjectEx returns, causing the loop to think it needs to wait another 49 days. This is most likely to happen when the machine is hibernated during WaitForSingleObjectEx. This makes acquiring a lock/event/etc from the _thread or threading module appear to never timeout. Replace with GetTickCount64 - this is OK now Python no longer supports XP which lacks it, and is in use for time.monotonic().

| | | | | | | | | | | | | | | | | | gcc -Wcast-qual turns up a number of instances of casting away constness of pointers. Some of these can be safely modified, by either: Adding the const to the type cast, as in: - return _PyUnicode_FromUCS1((unsigned char*)s, size); + return _PyUnicode_FromUCS1((const unsigned char*)s, size); or, Removing the cast entirely, because it's not necessary (but probably was at one time), as in: - PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno); + PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno); These changes will not change code, but they will make it much easier to check for errors in consts (cherry picked from commit e6be9b59a911626d6597fe148c32f0342bd2bd24) Co-authored-by: Andy Lester <andy@petdance.com>
