| | | | | | | | | | | | | | | (GH-10340) When the future returned by shield is cancelled, its completion callback of the inner future is not removed. This makes the callback list of inner inner future grow each time a shield is created and cancelled. This change unregisters the callback from the inner future when the outer future is cancelled. https://bugs.python.org/issue35125 (cherry picked from commit b35acc5b3a0148c5fd4462968b310fb436726d5a) Co-authored-by: Romain Picard <romain.picard@oakbits.com>
* bpo-31922: Do not connect UDP sockets when broadcast is allowed (GH-423)Miss Islington (bot)2019-05-072-7/+13
| | | | | | | | | | | | | | *Moved from python/asyncioGH-493.* This PR fixes issue python/asyncioGH-480, as explained in [this comment](https://github.com/python/asyncio/issues/480GH-issuecomment-278703828). The `_SelectorDatagramTransport.sendto` method has to be modified ~~so `_sock.sendto` is used in all cases (because it is tricky to reliably tell if the socket is connected or not). Could that be an issue for connected sockets?~~ *EDIT* ... so `_sock.send` is used only if `_sock` is connected. It also protects `socket.getsockname` against `OSError` in `_SelectorTransport`. This might happen on Windows if the socket is not connected (e.g. for UDP broadcasting). https://bugs.python.org/issue31922 (cherry picked from commit 63deaa5b70108ef441c57728322da6b4321db4fc) Co-authored-by: Vincent Michel <vxgmichel@gmail.com>

| | | | | | | | | | | | | | | | | | | The cancellation of an overlapped WSARecv() has a race condition which causes data loss because of the current implementation of proactor in asyncio. No longer cancel overlapped WSARecv() in _ProactorReadPipeTransport to work around the race condition. Remove the optimized recv_into() implementation to get simple implementation of pause_reading() using the single _pending_data attribute. Move _feed_data_to_bufferred_proto() to protocols.py. Remove set_protocol() method which became useless. (cherry picked from commit 79790bc35fe722a49977b52647f9b5fe1deda2b7) Co-authored-by: Victor Stinner <vstinner@redhat.com>

* bpo-32751: Wait for task cancellation in asyncio.wait_for() (GH-7216)Miss Islington (bot)2018-05-291-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | Currently, asyncio.wait_for(fut), upon reaching the timeout deadline, cancels the future and returns immediately. This is problematic for when *fut* is a Task, because it will be left running for an arbitrary amount of time. This behavior is iself surprising and may lead to related bugs such as the one described in bpo-33638: condition = asyncio.Condition() async with condition: await asyncio.wait_for(condition.wait(), timeout=0.5) Currently, instead of raising a TimeoutError, the above code will fail with `RuntimeError: cannot wait on un-acquired lock`, because `__aexit__` is reached _before_ `condition.wait()` finishes its cancellation and re-acquires the condition lock. To resolve this, make `wait_for` await for the task cancellation. The tradeoff here is that the `timeout` promise may be broken if the task decides to handle its cancellation in a slow way. This represents a behavior change and should probably not be back-patched to 3.6 and earlier.
