Release Notes for Klaytn v1.5.0

New features

• State migration (https://github.com/klaytn/klaytn/pull/507)

  • New JSON-RPC API to remove the unnecessary and old state/storage trie, saving the storage space for Klaytn node (Cypress) by 75% (800 GB -> 200 GB)
    • admin.startStateMigration()
    • admin.stopStateMigration()
    • admin.stateMigrationStatus
  • Klaytn node currently requires about 1TB of storage space. This size of storage was a burdensome for efficient node operation, and the state migration came here to relieve this. The state migration removes the stale state/storage trie nodes which are unnecessary for new block generation and validation. Before starting a state migration, stakingInfo is saved in a database to get stakingInfo without the staled state after the state migration.

• Warm-up trie node cache (https://github.com/klaytn/klaytn/pull/548)

  • New JSON-RPC APIs to speed up the block processing by iterating the latest state trie and caching it
    • debug.startWarmUp()
    • debug.stopWarmUp()
  • Until now, Klaytn node had to continuously access a database for processing a block due to uncached state trie nodes, which results in the delay in block processing. The introduced "warm-up" feature reduces this delay by iterating the last state trie and caching it.

• Import blocks from String (https://github.com/klaytn/klaytn/pull/516)

  • Importing blocks was available only with a file. Importing blocks from a string is required for some use cases.
  • New JSON-RPC APIs
    • admin.importChainFromString()

• Fastcache (https://github.com/klaytn/klaytn/pull/490)

  • Fastcache as trie node cache with the autoscaled cache size, reducing memory consumption compared to Bigcache

Improvements

• Parameterizes triesInMemory and maxRequestContentLength (https://github.com/klaytn/klaytn/pull/555, https://github.com/klaytn/klaytn/pull/564)
• Uses cached state database in TraceBlock (https://github.com/klaytn/klaytn/pull/546)
• Improves consensus logic
  • Adds unit test code (https://github.com/klaytn/klaytn/pull/487, https://github.com/klaytn/klaytn/pull/492)
  • Refactors SubList/SubListWithProposer (https://github.com/klaytn/klaytn/pull/551)
  • Prevents validators from sending consensus message if they are not in committee (https://github.com/klaytn/klaytn/pull/549)
  • Istanbul message handler now checks whether the sender is a member of the committee or not (https://github.com/klaytn/klaytn/pull/545)
• Prevents commit twice when a node stops (https://github.com/klaytn/klaytn/pull/530)
• Refactors staking manager (https://github.com/klaytn/klaytn/pull/515)
• Builds and publishes public docker image (https://github.com/klaytn/klaytn/pull/491)
• Improves Trace API
  • Adds txHash into txTraceResult (https://github.com/klaytn/klaytn/pull/488)
  • tracer now supports CREATE2 (https://github.com/klaytn/klaytn/pull/489)
  • tracer now reports transaction revert information (https://github.com/klaytn/klaytn/pull/484)
• Allows DNS address string to start with numeric character for encoding URL (https://github.com/klaytn/klaytn/pull/482)
• Removes vendor directory (https://github.com/klaytn/klaytn/pull/498)

Fixes

• Reorganizes the stop sequence of blockchain module (https://github.com/klaytn/klaytn/pull/535)
• Fixes computeStateDB to not compute for non-existing block number (https://github.com/klaytn/klaytn/pull/483)
• Prevents files to be overwritten via admin.exportChain (https://github.com/klaytn/klaytn/pull/480)
