blossom_upload_queue_shim_for_ndk 0.4.1

Offline-first wrapper around the ndk package's Blossom upload use case. Persists per-upload metadata to a sembast queue, reads blob bytes from a blossom_cache, and retries until every targeted server [...]

0.4.1

• Fix int64 overflow in computeBackoff on native platforms (Android, iOS, Linux, macOS, Windows). After ~52 failed attempts (with the default 5s initial delay), pow(2, attempts) wrapped to a negative integer, causing double.clamp to throw Invalid argument(s). The calculation now uses double arithmetic (pow(2.0, ...)) to avoid the overflow.

0.4.0

• Breaking (transitive on-disk): Bump blossom_cache to ^0.3.0. The cache database schema is bumped to version 2, so any cache written by blossom_cache 0.2.0 or earlier is dropped on first open after the upgrade. Queue records still in flight whose blob bytes lived only in the dropped cache will fail to retry. The BlossomCache API itself is unchanged, so no source changes are required in callers of this shim.
• IdbBlossomCache.open() now accepts a chunkSize parameter (default 1 MB) that fixes the Android CursorWindow ~2 MB row limit for large blobs when backed by sqflite.

0.3.0

• Breaking: Bump blossom_cache to ^0.2.0. The cache's put() now takes bytes positionally with sha256 as a named argument (cache.put(bytes, sha256: sha, type: 'image/png') instead of cache.put(sha, bytes, type: 'image/png')). Callers that populate the cache themselves before scheduling an upload must update those call sites.

0.2.0

• Bump ndk to ^0.8.4-dev.1 and forward the queue's sha256 to ndk.blossom.uploadBlob via the new precomputedSha256 parameter, so each retry skips re-hashing the blob bytes.
• Breaking: BlobUploadFn gains a required String precomputedSha256 named parameter. Custom implementations passed via the default constructor must accept it.

0.1.0

• Initial release.
• OfflineBlossomUpload shim around ndk.blossom.uploadBlob with sembast-backed queue metadata and blossom_cache-backed blob bytes.
• 100% delivery guarantee: every targeted server must ack before a record is marked delivered. Monotonic ackedServers and deliveredAt.
• upload() and reupload() with forcedServers semantics matching the broadcast shim.
• Cache pin ownership: the shim only releases pins it applied itself.
• Connectivity-aware retry loop via NDK relay connectivity as a proxy for internet reachability, plus a generic onlineSignal injection point.
