* [3.7] bpo-37170: Fix the cast on error in PyLong_AsUnsignedLongLongMask() ↵Zackery Spytz2019-06-071-0/+22
| | | | | | | (GH-13860) (GH-13896) (cherry picked from commit dc2476500d91082f0c907772c83a044bf49af279) Co-authored-by: Zackery Spytz <zspytz@gmail.com>
* [3.7] bpo-36389: _PyObject_IsFreed() now also detects uninitialized memory ↵Victor Stinner2019-04-111-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | (GH-12770) (GH-12788) * bpo-36389: _PyObject_IsFreed() now also detects uninitialized memory (GH-12770) Replace _PyMem_IsFreed() function with _PyMem_IsPtrFreed() inline function. The function is now way more efficient, it became a simple comparison on integers, rather than a short loop. It detects also uninitialized bytes and "forbidden bytes" filled by debug hooks on memory allocators. Add unit tests on _PyObject_IsFreed(). (cherry picked from commit 2b00db68554422ec37faba2a80179a0172df6349) * bpo-36389: Change PyMem_SetupDebugHooks() constants (GH-12782) Modify CLEANBYTE, DEADDYTE and FORBIDDENBYTE constants: use 0xCD, 0xDD and 0xFD, rather than 0xCB, 0xBB and 0xFB, to use the same byte patterns than Windows CRT debug malloc() and free().

* bpo-31173: Rewrite WSTOPSIG test of test_subprocess (#3055)Victor Stinner2017-08-101-0/+22
| | | | | | | | | | | | | The current test_child_terminated_in_stopped_state() function test creates a child process which calls ptrace(PTRACE_TRACEME, 0, 0) and then crash (SIGSEGV). The problem is that calling os.waitpid() in the parent process is not enough to close the process: the child process remains alive and so the unit test leaks a child process in a strange state. Closing the child process requires non-trivial code, maybe platform specific. Remove the functional test and replaces it with an unit test which mocks os.waitpid() using a new _testcapi.W_STOPCODE() function to test the WIFSTOPPED() path.

* bpo-30039: Don't run signal handlers while resuming a yield from stack (#1081)Nathaniel J. Smith2017-05-171-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we have a chain of generators/coroutines that are 'yield from'ing each other, then resuming the stack works like: - call send() on the outermost generator - this enters _PyEval_EvalFrameDefault, which re-executes the YIELD_FROM opcode - which calls send() on the next generator - which enters _PyEval_EvalFrameDefault, which re-executes the YIELD_FROM opcode - ...etc. However, every time we enter _PyEval_EvalFrameDefault, the first thing we do is to check for pending signals, and if there are any then we run the signal handler. And if it raises an exception, then we immediately propagate that exception *instead* of starting to execute bytecode. This means that e.g. a SIGINT at the wrong moment can "break the chain" – it can be raised in the middle of our yield from chain, with the bottom part of the stack abandoned for the garbage collector. The fix is pretty simple: there's already a special case in _PyEval_EvalFrameEx where it skips running signal handlers if the next opcode is SETUP_FINALLY. (I don't see how this accomplishes anything useful, but that's another story.) If we extend this check to also skip running signal handlers when the next opcode is YIELD_FROM, then that closes the hole – now the exception can only be raised at the innermost stack frame. This shouldn't have any performance implications, because the opcode check happens inside the "slow path" after we've already determined that there's a pending signal or something similar for us to process; the vast majority of the time this isn't true and the new check doesn't run at all.
