About this release

This is a maintenance Lima release.

• Refactor fetching of (forward) generations. This avoids a slow check for chain inclusion and will speedup v2/generations/height/<height> andv2/generations/hash/<kh_...>

• Added new metrics covering extended block information

  • ae.epoch.aemon.block.tx.total.micro : Number of transactions in a microblock

  • ae.epoch.aemon.block.gas.total.micro : Gas used per microblock

  • ae.epoch.aemon.block.gas.per_tx.micro : Gas used per transaction in a microblock

  • ae.epoch.aemon.block.size.per_tx.micro : Size of transactions in a microblock in bytes

  • ae.epoch.aecore.blocks.micro.txs_execution_time.success : Execution time of all transaction in a microblock in microseconds

  • ae.epoch.aecore.blocks.micro.txs_execution_time.error : Execution time of all transaction in a microblock in microseconds, when an error was encountered

  • ae.epoch.aecore.blocks.micro.insert_execution_time.success : Execution time of insertion of a microblock in microseconds

  • ae.epoch.aecore.blocks.micro.insert_execution_time.error : Execution time of failed insertion of a microblock in microseconds

  • ae.epoch.aecore.blocks.key.insert_execution_time.success : Execution time of insertion of a keyblock in microseconds

  • ae.epoch.aecore.blocks.key.insert_execution_time.error : Execution time of failed insertion of a keyblock in microseconds

• Added new metrics covering contract call information The following names act as templates for multiple specific metrics. The placeholders in these names are (in order) for ABI version, VM version, return type and actual info type. The return type may be ok, return or revert. The info type may be gas_used, execution_time in microseconds,state_size or call_data_size, both in bytes.

  • ae.epoch.aecore.contracts._._.ga_meta._._

  • ae.epoch.aecore.contracts._._.ga_attach._._

  • ae.epoch.aecore.contracts._._.contract_call._._

  • ae.epoch.aecore.contracts._._.contract_create._._

• Improve the algorithm in agree_on_height. It now starts looking near the top, and it keeps the right top hash during the whole algorithm.

• The default configuration for the Erlang runtime system has been adapted to use less CPU cores and threads. This should improve CPU contention on systems with fewer cores and improve responsiveness. For systems with 4+ CPU cores the settings can be increased if the node is experiencing any form of CPU limitations.
