[1.3.1] - 2021-07-24

Casper Node (casper-node/node/)

Added

• Add support for providing historical auction information via the addition of an optional block ID in the state_get_auction_info JSON-RPC.
• Exclude inactive validators from proposing blocks.
• Add validation of the [protocol] configuration on startup, to ensure the contained values make sense.
• Add optional outgoing bandwidth limiter to the networking component, controllable via new [network][max_outgoing_byte_rate_non_validators] config option.
• Add optional incoming message limiter to the networking component, controllable via new [network][max_incoming_message_rate_non_validators] config option.
• Add optional in-memory deduplication of deploys, controllable via new [storage] config options [enable_mem_deduplication] and [mem_pool_prune_interval].
• Add a new event stream to SSE server accessed via <IP:Port>/events/deploys which emits deploys in full as they are accepted.

Changed

• Major rewrite of the network component, covering connection negotiation and management, periodic housekeeping and logging.
• Exchange and authenticate Validator public keys in network handshake between peers.
• Remove needless copying of outgoing network messages.
• Move finality signatures to separate event stream and change stream endpoints to /events/main and /events/sigs.
• Avoid truncating the state root hash when reporting node's status via JSON-RPC or REST servers.
• The JSON-RPC server waits until an incoming deploy has been sent to storage before responding to the client.
• Persist event stream event index across node restarts.
• Separate transfers from other deploys in the block proposer.
• Enable getting validators for future eras in EffectBuilder::get_era_validators().
• Replace config option [block_propser][deploy_delay] (which specified a fixed delay before proposing a deploy) with a gossip-finished announcement.
• Improve logging around stalled consensus detection.
• Skip storage integrity checks if the node didn't previously crash.
• Update pinned version of Rust to nightly-2021-06-17
• Don't shut down by default anymore if stalled. To enable set config option shutdown_on_standstill = true in [consensus.highway].

Removed

• Remove systemd notify support, including removal of [network][systemd_support] config option.

Fixed

• Avoid redundant requests caused by the Highway synchronizer.
• Update "current era" metric also for initial era.
• Keep syncing until the node is in the current era, rather than allowing an acceptable drift.
• Update the list of peers with newly-learned ones in linear chain sync.
• Drain the joiner reactor queue on exit, to eliminate stale connections whose handshake has completed, but which live on the queue.
• Shut down SSE event streams gracefully.
• Limit the maximum number of clients connected to the event stream server via the [event_stream_server][max_concurrent_subscribers] config option.
• Avoid emitting duplicate events in the event stream.
• Change BlockIdentifier params in the Open-RPC schema to be optional.
