[issue46430] intern strings in deepfrozen modules

STINNER Victor added the comment: _PyStaticCode_InternStrings() error handling is based on assert(): that's really bad. It can crash Python (exit with abort()) at the first memory allocation failure. Why not returning -1 on error? -- ___ Python

[issue46829] Confusing CancelError message if multiple cancellations are scheduled

Serhiy Storchaka added the comment: For reference, the msg parameter of Task.cancel() was added in issue31033. It seems that the initial use case was for debugging. I do not see how it differs from the following example: r = random.random() if r < 0.5: x = 0 else:

[issue46771] Add some form of cancel scopes

Guido van Rossum added the comment: To make this cleanly interact with timeout, TaskGroup etc., the CancelOnEvent class should have a "did-I-cancel" flag which is set in the _cancel_on_event() callback. Then if that flag is set it should call .uncancel(), and if that returns a value > 0, it

[issue46622] Add an async variant of lru_cache for coroutines.

Serhiy Storchaka added the comment: async_lru_cache() and async_cached_property() can be written using that decorator. The implementation of async_lru_cache() is complicated because the interface of lru_cache() is complicated. But it is simpler than using _lru_cache_wrapper(). def

[issue46829] Confusing CancelError message if multiple cancellations are scheduled

Guido van Rossum added the comment: But that example is made-up. Is there a real-world situation where you need to know the call site, and it wouldn't be obvious from other log messages? Directly cancelling a task without also somehow catching the cancellation (like in the timeout or task

[issue46622] Add an async variant of lru_cache for coroutines.

Serhiy Storchaka added the comment: I think that it would be simpler to add a decorator which wraps the result of an asynchronous function into an object which can be awaited more than once: def reawaitable(func): @wraps(func) def wrapper(*args, **kwargs): return
