ava-labs/avalanchego v1.9.4

Banff.4 - VM BLS Access

on GitHub

This version is backwards compatible to v1.9.0. It is optional, but encouraged. The supported plugin version is 20.

This version modifies the db format. The db format is compatible with v1.9.3, but not v1.9.2 or earlier. After running a node with v1.9.4 attempting to run a node with a version earlier than v1.9.3 may report a fatal error on startup.

PeerList Gossip Optimization

• Added gossip tracking to the peer instance to only gossip new IPs to a connection
• Added PeerListAck message to report which TxIDs provided by the PeerList message were tracked
• Added TxIDs to the PeerList message to unique-ify nodeIDs across validation periods
• Added TxID mappings to the gossip tracker

Validator Set Tracking

• Renamed GetValidators to Get on the validators.Manager interface
• Removed Set, AddWeight, RemoveWeight, and Contains from the validators.Manager interface
• Added Add to the validators.Manager interface
• Removed Set from the validators.Set interface
• Added Add and Get to the validators.Set interface
• Modified validators.Set#Sample to return ids.NodeID rather than valdiators.Validator
• Replaced the validators.Validator interface with a struct
• Added a BLS public key field to validators.Validator
• Added a TxID field to validators.Validator
• Improved and documented error handling within the validators.Set interface
• Added BLS public keys to the result of GetValidatorSet
• Added BuildBlockWithContext as an optional VM method to build blocks at a specific P-chain height
• Added VerifyWithContext as an optional block method to verify blocks at a specific P-chain height

Uptime Tracking

• Added ConnectedSubnet message handling to the chain handler
• Added SubnetConnector interface and implemented it in the platformvm
• Added subnet uptimes to p2p pong messages
• Added subnet uptimes to platform.getCurrentValidators
• Added subnetID as an argument to info.Uptime

Fixes

• Fixed incorrect context cancellation of escaped contexts from grpc servers
• Fixed race condition between API initialization and shutdown
• Fixed race condition between NAT traversal initialization and shutdown
• Fixed race condition during beacon connection tracking
• Added race detection to the E2E tests
• Added additional message and sender tests

Coreth

• Improved header and logs caching using maximum accepted depth cache
• Added config option to perform database inspection on startup
• Added configurable transaction indexing to reduce disk usage
• Added special case to allow transactions using Nick's Method to bypass API level replay protection
• Added counter metrics for number of accepted/processed logs

APIs

• Added indices to the return values of GetLastAccepted and GetContainerByID on the indexer API client
• Removed unnecessary locking from the info API

Chain Data

• Added ChainDataDir to the snow.Context to allow blockchains to canonically access disk outside avalanchego's database
• Added --chain-data-dir as a CLI flag to specify the base directory for all ChainDataDirs

Miscellaneous

• Removed Version from the peer.Network interface
• Removed Pong from the peer.Network interface
• Reduced memory allocations inside the system throttler
• Added CChainID to the snow.Context
• Converted all sorting to utilize generics
• Converted all set management to utilize generics
