durable_queue_dio 0.2.1

Dio integration for durable_queue. Retry rules for HTTP errors, Retry-After, idempotency headers, cancellation, and queued HTTP requests.

0.2.1

• When a request gets a 429 or 503 with a Retry-After header and a per-host limit exists (addHttpHostRateLimit), the host's bucket is held for that time, so every queued request to the host waits. registerHttpRequests takes hostRateLimit (default 'http-host', null to turn it off).
• HttpRequestTask.hostOfUrl(url, baseUrl:).
• defaultHostRateLimit constant.
• Requires durable_queue 0.5.3 or later.

0.2.0

• registerHttpRequests takes requires, deferOn, and rateLimit and passes them to DurableQueue.register, so queued requests can wait for a network gate and be rate limited.
• DioRetryRules.deferOn(gate): a register(deferOn:) rule that turns connection errors (connectionError, connectionTimeout) into a wait for the gate instead of a failed attempt. DioRetryRules.isConnectionError exposes the same check.
• queue.addHttpHostRateLimit(limit, dio:): a rate limit per API host for queued requests. Relative URLs are resolved against the Dio baseUrl.
• HttpRequestTask.hostOf(task, baseUrl:): the host a stored request goes to.
• Requires durable_queue 0.5.0 or later (>=0.5.0 <0.6.0).

0.1.1

• Allow durable_queue 0.5.x (>=0.4.0 <0.6.0). No code change.

0.1.0

• Initial release.
• DioRetryRules: retries timeouts, connection failures, and HTTP 408, 425, 429, 500, 502, 503, 504 by default; honors Retry-After (seconds or HTTP-date) up to a configurable maximum. Use rules.shouldRetry as retryIf and rules.retryDelay as retryDelay.
• parseRetryAfter for Retry-After header values. Two-digit years in RFC 850 dates follow the RFC 9110 50-year rule with every http_parser 4.x.
• TaskContext helpers: dioCancelToken() aborts the request when the task is cancelled; withIdempotencyKey() sends the task's idempotency key as a header (default Idempotency-Key).
• HttpRequestTask and queue.registerHttpRequests(dio): queue HTTP requests (method, URL, headers, query, JSON or text body) without writing a task class, with an optional onResponse callback.
• Requires durable_queue 0.4.0 and dio 5.11.1 or later.
