흔히 이렇게 알고 있다

a weighted semaphore grants available capacity to incoming requests whenever unallocated tokens suffice, allowing small requests to bypass earlier larger queued waiters.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• assert semaphore.Weighted enforces strict FIFO ordering so smaller Acquire requests remain blocked behind a larger head waiter even when sufficient unallocated tokens exist
• assert TryAcquire returns false whenever waiters are queued in the wait list even if unallocated capacity is available
• assert canceling a blocked head waiter context immediately unblocks subsequent queued waiters without requiring an additional Release
• assert calling Acquire with an already-canceled context returns context.Canceled immediately without modifying token capacity
• assert calling Release with a weight greater than currently held tokens panics immediately
