CPython provides Queue, Semaphore, BoundedSemaphore and Condition in addition to the provided Lock and Event classes.

In the case of Queue the issue was raised in https://github.com/micropython/micropython/issues/5828.

extmod uasyncio: Lock RuntimeError CPython compatibility

Lock should raise a RuntimeError with an error message like CPython does.

Assessment

Q Qwen · high

The query (issue #5858) is a feature request to add CPython's synchronization primitives (Queue, Semaphore, BoundedSemaphore, Condition) to MicroPython's uasyncio module. The candidate (PR #5799) is a bug fix that improves CPython compatibility for the existing Lock class by making it raise RuntimeError with the correct message. While both items relate to uasyncio synchronization primitives and CPython compatibility, the PR does not implement the requested new primitives (Queue, Semaphore, etc.) - it only fixes behavior of an existing primitive (Lock). The PR addresses a different aspect of the same general topic.

Suggested action

Keep both items open. The PR improves Lock compatibility but does not resolve the feature request for new synchronization primitives.
