* bpo-30038: fix race condition in signal delivery + wakeup fd (#1082) (#2075)Victor Stinner2017-06-101-7/+26
| | | | | | | | | | | | | | | | | | | | Before, it was possible to get the following sequence of events (especially on Windows, where the C-level signal handler for SIGINT is run in a separate thread): - SIGINT arrives - trip_signal is called - trip_signal writes to the wakeup fd - the main thread wakes up from select()-or-equivalent - the main thread checks for pending signals, but doesn't see any - the main thread drains the wakeup fd - the main thread goes back to sleep - trip_signal sets is_tripped=1 and calls Py_AddPendingCall to notify the main thread the it should run the Python-level signal handler - the main thread doesn't notice because it's asleep This has been causing repeated failures in the Trio test suite: https://github.com/python-trio/trio/issues/119 (cherry picked from commit 4ae01496971624c75080431806ed1c08e00f22c7)
* [3.6] bpo-30039: Don't run signal handlers while resuming a yield from stack ↵Yury Selivanov2017-06-091-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-1081) (#1640) 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..

* [3.6] bpo-29723: Consistently configure sys.path[0] (#636)Nick Coghlan2017-03-121-28/+44
| | | | | | | | | | | | | | | | | | | | | | | | Directory and zipfile execution previously added the parent directory of the directory or zipfile as sys.path[0] and then subsequently overwrote it with the directory or zipfile itself. This caused problems in isolated mode, as it overwrote the "stdlib as a zip archive" entry in sys.path, as the parent directory was never added. The attempted fix to that issue in bpo-29319 created the opposite problem in *non*-isolated mode, by potentially leaving the parent directory on sys.path instead of overwriting it. This change fixes the root cause of the problem by removing the whole "add-and-overwrite" dance for sys.path[0], and instead simply never adds the parent directory to sys.path in the first place.
