* bpo-30039: Don't run signal handlers while resuming a yield from stack (#1081)Nathaniel J. Smith2017-05-171-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* bpo-30225: Fix is_valid_fd() on macOS Tiger (#1443)Victor Stinner2017-05-031-0/+9
| | | | | is_valid_fd() now uses fstat() instead of dup() on macOS to return 0 on a pipe when the other side of the pipe is closed. fstat() fails with EBADF in that case, whereas dup() succeed.

* bpo-29676: fix lsprof can't profile C method call. (GH523)INADA Naoki2017-03-071-1/+14
| | | | | | | | | | When LOAD_METHOD is used for calling C mehtod, PyMethodDescrObject was passed to profilefunc from 5566bbb. But lsprof traces only PyCFunctionObject. Additionally, there can be some third party extension which assumes passed arg is PyCFunctionObject without calling PyCFunction_Check(). So make PyCFunctionObject from PyMethodDescrObject when tstate->c_profilefunc is set.

* bpo-29622: Make AST constructor to accept less than enough number of ↵INADA Naoki2017-02-231-19/+17
| | | | | | | | | | | positional arguments (GH-249) bpo-29463 added optional "docstring" field to 4 AST types. While it is optional, it breaks backward compatibility because AST constructor requires number of positional argument is same to number of fields. AST types accepts empty arguments, and incomplete keyword arguments. But it's not big problem because field can be filled after creation, and checked when compiling. So stop requiring complete set of fields for positional arguments too.
* bpo-28598: Support __rmod__ for RHS subclasses of str in % string formatting ↵Martijn Pieters2017-02-231-3/+9
| | | | | | | | operations (#51) When you use `'%s' % SubClassOfStr()`, where `SubClassOfStr.__rmod__` exists, the reverse operation is ignored as normally such string formatting operations use the `PyUnicode_Format()` fast path. This patch tests for subclasses of `str` first and picks the slow path in that case. Patch by Martijn Pieters.
