* [3.8] bpo-39562: Prevent collision of future and compiler flags (GH-19230) ↵Pablo Galindo2020-05-011-1/+1
| | | | | | | | | | | (GH-19835) The constant values of future flags in the __future__ module is updated in order to prevent collision with compiler flags. Previously PyCF_ALLOW_TOP_LEVEL_AWAIT was clashing with CO_FUTURE_DIVISION.. (cherry picked from commit 4454057269b995341b04d13f0bf97f96080f27d0) Co-authored-by: Batuhan Taşkaya <batuhanosmantaskaya@gmail.com>
* bpo-40048: Fix _PyCode_InitOpcache() error path (GH-19691) (GH-19698)Victor Stinner2020-04-241-1/+1
| | | | | | | | If _PyCode_InitOpcache() fails in _PyEval_EvalFrameDefault(), use "goto exit_eval_frame;" rather than "return NULL;" to exit the function in a consistent state. For example, tstate->frame is now reset properly. (cherry picked from commit 25104949a5a60ff86c10691e184ce2ecb500159b)

* bpo-20526: Fix PyThreadState_Clear(): don't decref frame (GH-19120) (GH-19136)Victor Stinner2020-03-241-2/+10
| | | | | | | | | | 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.

* 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>

* Fix compiler warning on Windows (GH-18012)Miss Islington (bot)2020-01-151-1/+1
| | | | | | | | | | | Python-ast.h contains a macro named Yield that conflicts with the Yield macro in Windows system headers. While Python-ast.h has an "undef Yield" directive to prevent this, it means that Python-ast.h must be included before Windows header files or we run into a re-declaration warning. In commit c96be811fa7d an include for pycore_pystate.h was added which indirectly includes Windows header files. In this commit we re-order the includes to fix this warning.
