ar-io/ar-io-node r41

Release 41

on GitHub

Upgrading to this release is recommended but not urgent due to improvements in peer data fetching safety.

Added

• Added preferred chunk GET node URLs configuration via PREFERRED_CHUNK_GET_NODE_URLS environment variable to enable chunk-specific peer prioritization. Preferred URLs receive a weight of 100 for prioritization and the system selects 10 peers per attempt by default.
• Added hash validation for peer data fetching by including X-AR-IO-Expected-Digest header in peer requests when hash is available, validating peer responses against expected hash, and immediately rejecting mismatched data.
• Added DOCKER_NETWORK_NAME environment variable to configure the Docker network name used by Docker Compose.
• Added draft guide for running a community gateway.
• Added draft data verification architecture document.

Changed

• Removed trusted node fallback for chunk retrieval. Chunks are now retrieved exclusively from peers, with the retry count increased from 3 to 50 to ensure reliability without the trusted node fallback.

Fixed

• Fixed inverted logic preventing symlink creation in FsChunkDataStore.
• Fixed Content-Length header for range requests and 304 responses, properly setting header for single and multipart range requests and removing entity headers from 304 Not Modified responses per RFC 7232.
• Fixed MaxListenersExceeded warnings by adding setMaxListeners to read-through data cache.
• Fixed potential memory leaks in read-through data cache by using once instead of on for error and end event listeners.
