Cloudflare Sandbox SDK v0.12.5：新增追踪跨度、修复销毁与并发问题
@cloudflare/[email protected]
- #786 750ca4d Thanks @aron-cf! - Instrument the bridge API with Cloudflare custom spans. Each endpoint now emits
- a bridge.<operation> span annotated with the sandbox ID, container UUID, and
- operation-specific metadata (command, file path, port, session ID, and so on),
- so requests are traceable end to end. Enable tracing with
- observability.traces.enabled in your Worker configuration.
- #799 0783596 Thanks @aron-cf! - Make destroy() succeed when the sandbox container was never admitted, so cleanup no longer fails with a no-instance platform error.
- #799 0783596 Thanks @aron-cf! - Reduce intermittent startup failures during concurrent sandbox creation where operations could fail with a disposed RPC session error.
- #799 0783596 Thanks @aron-cf! - Surface container capacity and admission failures as retryable ContainerUnavailableError with a structured reason, including no-instance and max-instances cases. Callers can branch on error.reason instead of parsing platform messages.
- #786 750ca4d Thanks @aron-cf! - Fill the warm pool in bounded-parallel batches instead of one container at a
- time, so it primes and recovers far faster after a burst. Tune the batch size
- with WARM_POOL_SCALE_BATCH_SIZE (default 5, clamped to 20).
- #786 750ca4d Thanks @aron-cf! - Refill the warm pool the moment it drains instead of waiting for the next
- background tick. After a burst consumes warm containers, replenishment now
- starts immediately, cutting the latency tail for sandboxes created during
- sustained or back-to-back bursts.
- #786 750ca4d Thanks @aron-cf! - Let the warm pool know its instance ceiling up front via the
- WARM_POOL_MAX_INSTANCES bridge variable. Set it to match your container's
- max_instances so the pool makes correct capacity decisions without first
- crashing into the limit. 0 (the default) preserves the existing auto-learn
- behaviour.
