[issue45098] asyncio.CancelledError should contain more information on cancellations

Sam Bull added the comment: I think there's still a problem, in that the user still expects a task to be cancelled in the example previously: https://github.com/aio-libs/async-timeout/issues/229#issuecomment-908502523 If we encounter the race condition where the timeout cancels the tas

[issue46771] Add some form of cancel scopes

Sam Bull added the comment: > If the task is already pending a cancellation targeted at a cancel scope, the > task itself cannot be cancelled anymore since calling cancel() again on the > task is a no-op. This would be solved by updating the cancel message on the > second call

[issue46771] Add some form of cancel scopes

Sam Bull added the comment: > This should be solved when using the cancel count -- the explicit cancel > bumps the cancel count so the cancel scope (i.e. timeout()) will not raise > TimeoutError. It will probably work in this case. But, what about more complex cases? If th

[issue46771] Add some form of cancel scopes

Sam Bull added the comment: Actually, in your counter proposal, you say: > Such context managers should still keep track of whether they cancelled the > task themselves or not, and if they did, they should always call t.uncancel(). But, if we are using nonces on the CancelledError t

[issue46771] Add some form of cancel scopes

[issue46771] Add some form of cancel scopes

Sam Bull added the comment: > We could store the nonces in a single CancelledError instead. Indeed, my initial proposal was exactly that, but after learning about ExceptionGroup, I thought that was a cleaner approach. -- ___ Python trac

[issue8797] urllib2 basicauth broken in 2.6.5: RuntimeError: maximum recursion depth exceeded in cmp

Sam Bull added the comment: I think there's a much simpler solution to this ticket than the retry logic that's currently in place. The code originally avoided the infinite recursion by checking to see if the previous request had already submitted the auth credentials that would b

Sam Bull added the comment: There is still an issue here. I proposed a possible solution at: https://github.com/python/cpython/pull/28149#issuecomment-1007823782 You can also scroll up through the lengthy discussion to see how I reached that conclusion. I've not had time yet to actuall

[issue44815] asyncio.gather no DeprecationWarning if task are passed

New submission from Sam Bull : When calling asyncio.gather() a DeprecationWarning is only emitted if no tasks are passed (which is probably the exceptional case, rather than the standard one). This has resulted in us missing this deprecated argument in aiohttp until we received a bug report

Sam Bull added the comment: There is another issue with asyncio.sleep() too, if the passed argument is 0. This also tripped up the tests in aiohttp (though I've also used an explicit 0 in production code to yield back to the loop). -- ___ P

[issue45098] asyncio.CancelledError should contain more information on cancellations

New submission from Sam Bull : There are awkward edge cases caused by race conditions when cancelling tasks which make it impossible to reliably cancel a task. For example, in the async-timeout library there appears to be no way to avoid suppressing an explicit t.cancel() if that
