* [3.6] bpo-30899: Add unittests, 100% coverage, for IDLE's two ConfigParser ↵terryjreedy2017-07-121-0/+1
| | | | | | subclasses. (GH-2662) (#2685) Patch by Louie Lu. (cherry picked from commit 50c9435)
* [3.6] bpo-30879: os.listdir() and os.scandir() now emit bytes names when ↵Serhiy Storchaka2017-07-112-3/+27
| | | | | | (GH-2634) (#2656) called with bytes-like argument.. (cherry picked from commit 1180e5a51871fa53ca6892e83fd2e69dc2600447)
* [3.6] bpo-29854: Fix segfault in call_readline() (GH-728)Nir Soffer2017-07-081-3/+47
| | | | | | | | | | | | | If history-length is set in .inputrc, and the history file is double the history size (or more), history_get(N) returns NULL, and python segfaults. Fix that by checking for NULL return value. It seems that the root cause is incorrect handling of bigger history in readline, but Python should not segfault even if readline returns unexpected value. This issue affects only GNU readline. When using libedit emulation system history size option does not work.
* bpo-30532: Fix whitespace folding in certain cases (#2591)Joel Hillacre2017-07-061-0/+12
| | | Leading whitespace was incorrectly dropped during folding of certain lines in the _header_value_parser's folding algorithm. This makes the whitespace handling code consistent.

* [3.6] bpo-30039: Don't run signal handlers while resuming a yield from stack ↵Yury Selivanov2017-06-091-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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..
