| | | | | | | | | | | | | | | [locks] (GH-13920) This PR deprecate explicit loop parameters in all public asyncio APIs This issues is split to be easier to review. Third step: locks.py https://bugs.python.org/issue36373

* bpo-32751: Wait for task cancellation in asyncio.wait_for() (GH-7216)Elvis Pranskevichus2018-05-291-0/+13
| | | | | | | | | | | | | | | | | | | | | | | 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.

* asyncio: sync with TulipVictor Stinner2014-07-291-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | * _WaitHandleFuture.cancel() now notify IocpProactor through the overlapped object that the wait was cancelled. * Optimize IocpProactor.wait_for_handle() gets the result if the wait is signaled immediatly. * Enhance representation of Future and Future subclasses - Add "created at filename:lineno" in the representation - Add Future._repr_info() method which can be more easily overriden than Future.__repr__(). It should now be more easy to enhance Future representation without having to modify each subclass. For example, _OverlappedFuture and _WaitHandleFuture get the new "created at" information. - Use reprlib to format Future result, and function arguments when formatting a callback, to limit the length of the representation. * Fix repr(_WaitHandleFuture) * _WaitHandleFuture and _OverlappedFuture: hide frames of internal calls in the source traceback. * Cleanup ProactorIocp._poll(): set the timeout to 0 after the first call to GetQueuedCompletionStatus() * test_locks: close the temporary event loop and check the condition lock * Remove workaround in test_futures, no more needed

* Update asyncio from the Tulip projectVictor Stinner2014-01-251-123/+120
| | | | | | | | | | | | | | | | Major changes: - StreamReader.readexactly() now raises an IncompleteReadError if the end of stream is reached before we received enough bytes, instead of returning less bytes than requested. - Unit tests use the main asyncio module instead of submodules like events - _UnixWritePipeTransport now also supports character devices, as _UnixReadPipeTransport. Patch written by Jonathan Slenders. - Export more symbols: BaseEventLoop, BaseProactorEventLoop, BaseSelectorEventLoop, Queue and Queue sublasses, Empty, Full
