* [3.7] bpo-34872: Fix self-cancellation in C implementation of asyncio.Task ↵Elvis Pranskevichus2018-10-031-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | (GH-9679) (GH-9691) The C implementation of asyncio.Task currently fails to perform the cancellation cleanup correctly in the following scenario. async def task1(): async def task2(): await task3 # task3 is never cancelled asyncio.current_task().cancel() await asyncio.create_task(task2()) The actuall error is a hardcoded call to `future_cancel()` instead of calling the `cancel()` method of a future-like object. Thanks to Vladimir Matveev for noticing the code discrepancy and to Yury Selivanov for coming up with a pathological scenario..

* bpo-34783: Fix Py_Main() (GH-9526)Victor Stinner2018-09-241-79/+84
| | | | | | | | | | | | | | | Fix a crash with musl libc (on Alpine Linux) when the script filename specified on the command line doesn't exist. pymain_open_filename() now gets the current core configuration from the interpreter state. Modify the code to make it closer to the master branch: * Rename _Py_CommandLineDetails to _PyCmdline * Remove _PyMain.config: replaced with a local variable 'local_config' in pymain_init() * Reorganize pymain_main(): move code using the "local config" into pymain_init() * As soon as possible, switch from the local config to the core configuration attached to the interpreter.

* bpo-34759: Fix error handling in ssl 'unwrap()' (GH-9468)Miss Islington (bot)2018-09-221-2/+2
| | | | | | | | | | | | | | | | | OpenSSL follows the convention that whenever you call a function, it returns an error indicator value; and if this value is negative, then you need to go look at the actual error code to see what happened. Commit c6fd1c1c3a introduced a small mistake in _ssl__SSLSocket_shutdown_impl: instead of checking whether the error indicator was negative, it started checking whether the actual error code was negative, and it turns out that the error codes are never negative. So the effect was that 'unwrap()' lost the ability to raise SSL errors. https://bugs.python.org/issue34759 (cherry picked from commit c0da582b227f311126e278b5553a7fa89c79b054) Co-authored-by: Nathaniel J.

| | | | | | | | | | | | | | | | | When subprocess.Popen() stdin= stdout= or stderr= handles are specified and appear in pass_fds=, don't close the original fds after dup'ing them. This implementation and unittest primarily came from @izbyshev (see the PR) See also https://github.com/izbyshev/cpython/commit/b89b52f28490b69142d5c061604b3a3989cec66c This also removes the old manual p2cread, c2pwrite, and errwrite closing logic as inheritable flags and _close_open_fds takes care of that properly today without special treatment. This code is within child_exec() where it is the only thread so there is no race condition between the dup and _Py_set_inheritable_async_safe call.

| | | | | | | | | | | | | | | | | | | | | | | code points (GH-8862) The current C implementations **crash** if the input includes a surrogate Unicode code point, which is not possible to encode in UTF-8. Important notes: 1. It is possible to pass a non-UTF-8 string as a separator to the `.isoformat()` methods. 2. The pure-Python `datetime.fromisoformat()` implementation accepts strings with a surrogate as the separator. In `datetime.fromisoformat()`, in the special case of non-UTF-8 separators, this implementation will take a performance hit by making a copy of the input string and replacing the separator with 'T'.
