v1.7.11

This version is backwards compatible to v1.7.0. It is optional, but encouraged.

The first startup of the C-Chain will cause an increase in CPU and IO usage due to an index update. This index update runs in the background and does not impact restart time.

State Sync

• Added state syncer engine to facilitate VM state syncing, rather than full historical syncing
• Added GetStateSummaryFrontier, StateSummaryFrontier, GetAcceptedStateSummary, AcceptedStateSummary as P2P messages
• Updated Ancestors message specification to expect an empty response if the container is unknown
• Added --state-sync-ips and --state-sync-ids flags to allow manual overrides of which nodes to query for accepted state summaries
• Updated networking library to permanently track all manually tracked peers, rather than just beacons
• Added state sync support to the metervm
• Added state sync support to the proposervm
• Added state sync support to the rpcchainvm
• Added beta state sync support to coreth

ProposerVM

• Prevented rejected blocks from overwriting the proposervm height index
• Optimized proposervm block rewind to utilize the height index if available
• Ensured proposervm height index is marked as repaired in Initialize if it is fully repaired on startup
• Removed --reset-proposervm-height-index. The height index will be reset upon first restart
• Optimized proposervm height index resetting to periodically flush deletions

Bug Fixes

• Fixed IPC message issuance and restructured consensus event callbacks to be checked at compile time
• Fixed coreth metrics initialization
• Fixed bootstrapping startup logic to correctly startup if initially connected to enough stake
• Fixed coreth panic during metrics collection
• Fixed panic on concurrent map read/write in P-chain wallet SDK
• Fixed rpcchainvm panic by sanitizing http response codes
• Fixed incorrect JSON tag on platformvm.BaseTx
• Fixed AppRequest, AppResponse, and AppGossip stringers used in logging

API/Client

• Supported client implementations pointing to non-standard URIs
• Introduced ids.NodeID type to standardize logging and simplify API service and client implementations
• Changed client implementations to use standard types rather than strings wherever possible
• Added subnetID as an argument to platform.getTotalStake
• Added connected to the subnet validators in responses to platform.getCurrentValidators and platform.getPendingValidators
• Add missing admin API client methods
• Improved indexer API client implementation to avoid encoding edge cases

Networking

• Added --snow-mixed-query-num-push-vdr and --snow-mixed-query-num-push-non-vdr to allow parameterization of sending push queries
  • By default, non-validators now send only pull queries, not push queries.
  • By default, validators now send both pull queries and push queries upon inserting a container into consensus. Previously, nodes sent only push queries.
• Added metrics to track the amount of over gossipping of peerlist messages
• Added custom message queueing support to outbound Peer messages
• Reused Ping messages to avoid needless memory allocations

Logging

• Replaced AvalancheGo's internal logger with uber-go/zap.
• Replaced AvalancheGo's log rotation with lumberjack.
• Renamed log-display-highlight to log-format and added json option.
• Added log-rotater-max-size, log-rotater-max-files, log-rotater-max-age, log-rotater-compress-enabled options for log rotation.

Miscellaneous

• Added --data-dir flag to easily move all default file locations to a custom location
• Standardized RPC specification of timestamp fields
• Logged health checks whenever a failing health check is queried
• Added callback support for the validator set manager
• Increased coreth trie tip buffer size to 32
• Added CPU usage metrics for AvalancheGo and all sub-processes
• Added Disk IO usage metrics for AvalancheGo and all sub-processes

Cleanup

• Refactored easily separable platformvm files into separate smaller packages
• Simplified default version parsing
• Fixed various typos
• Converted some structs to interfaces to better support mocked testing
• Refactored IP utils

Documentation

• Increased recommended disk size to 1 TB
• Updated issue template
• Documented additional snowman.Block invariants
