* bpo-20526: Fix PyThreadState_Clear(): don't decref frame (GH-19120) ↵Victor Stinner2020-03-241-2/+10
| | | | | | | | | | | | | (GH-19136) (GH-19137) PyThreadState.frame is a borrowed reference, not a strong reference: PyThreadState_Clear() must not call Py_CLEAR(tstate->frame). Remove test_threading.test_warnings_at_exit(): we cannot warranty that the Python thread state of daemon threads is cleared in a reliable way during Python shutdown.

* [3.7] bpo-39847: EnterNonRecursiveMutex() uses GetTickCount64() (GH-18780) ↵bobince2020-03-121-3/+3
| | | | | | | | | | | | | | | | | | | | (GH-18959) 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().

* [3.8] bpo-37409: fix relative import with no parent (GH-14956) (GH-15913)Miss Islington (bot)2019-09-111-10/+13
| | | | | | | | | | | | | | | | | | | Relative imports use resolve_name to get the absolute target name, which first seeks the current module's absolute package name from the globals: If __package__ (and __spec__.parent) are missing then import uses __name__, truncating the last segment if the module is a submodule rather than a package __init__.py (which it guesses from whether __path__ is defined). The __name__ attempt should fail if there is no parent package (top level modules), if __name__ is '__main__' (-m entry points), or both (scripts). That is, if both __name__ has no subcomponents and the module does not seem to be a package __init__ module then import should fail..
