* bpo-35504: Fix segfaults and SystemErrors when deleting certain attrs. ↵Zackery Spytz2018-12-171-0/+9

* bpo-34890: Make iscoroutinefunction, isgeneratorfunction and ↵Pablo Galindo2018-10-261-2/+2
| | | | | | | | | | | isasyncgenfunction work with functools.partial (GH-9903) inspect.isfunction() processes both inspect.isfunction(func) and inspect.isfunction(partial(func, arg)) correctly but some other functions in the inspect module (iscoroutinefunction, isgeneratorfunction and isasyncgenfunction) lack this functionality. This commits adds a new check in the mentioned functions in the inspect module so they can work correctly with arbitrarily nested partial functions.
* bpo-34872: Fix self-cancellation in C implementation of asyncio.Task (GH-9679)Elvis Pranskevichus2018-10-031-0/+36
| | | | | | | | | | | | | | | | | 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-32751: Wait for task cancellation in asyncio.wait_for() (GH-7216)Elvis Pranskevichus2018-05-291-0/+56
| | | | | | | | | | | | | | | | | | | | | | | 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.
