Version v0.31.0

Added

• #2014: Added a separate thread for the block importer.
• #2013: Added a separate thread to process P2P database lookups.
• #2004: Added new CLI argument continue-services-on-error to control internal flow of services.
• #2004: Added handling of incorrect shutdown of the off-chain GraphQL worker by using state rewind feature.
• #2007: Improved metrics:
  • Added database metrics per column.
  • Added statistic about commit time of each database.
  • Refactored how metrics are registered: Now, we use only one register shared between all metrics. This global register is used to encode all metrics.
• #1996: Added support for rollback command when state rewind feature is enabled. The command allows the rollback of the state of the blockchain several blocks behind until the end of the historical window. The default historical window it 7 days.
• #1996: Added support for the state rewind feature. The feature allows the execution of the blocks in the past and the same execution results to be received. Together with forkless upgrades, execution of any block from the past is possible if historical data exist for the target block height.
• #1994: Added the actual implementation for the AtomicView::latest_view.
• #1972: Implement AlgorithmUpdater for GasPriceService
• #1948: Add new AlgorithmV1 and AlgorithmUpdaterV1 for the gas price. Include tools for analysis
• #1676: Added new CLI arguments:
  • graphql-max-depth
  • graphql-max-complexity
  • graphql-max-recursive-depth

Changed

• #2015: Small fixes for the database:
  • Fixed the name for historical columns - Metrics was working incorrectly for historical columns.
  • Added recommended setting for the RocksDB - The source of recommendation is official documentation https://github.com/facebook/rocksdb/wiki/Setup-Options-and-Basic-Tuning#other-general-options.
  • Removed repairing since it could corrupt the database if fails - Several users reported about the corrupted state of the database after having a "Too many descriptors" error where in logs, repairing of the database also failed with this error creating a lost folder.
• #2010: Updated the block importer to allow more blocks to be in the queue. It improves synchronization speed and mitigate the impact of other services on synchronization speed.
• #2006: Process block importer events first under P2P pressure.
• #2002: Adapted the block producer to react to checked transactions that were using another version of consensus parameters during validation in the TxPool. After an upgrade of the consensus parameters of the network, TxPool could store invalid Checked transactions. This change fixes that by tracking the version that was used to validate the transactions.
• #1999: Minimize the number of panics in the codebase.
• #1990: Use latest view for mutate GraphQL queries after modification of the node.
• #1992: Parse multiple relayer contracts, RELAYER-V2-LISTENING-CONTRACTS env variable using a , delimiter.
• #1980: Add Transaction to relayer 's event filter

Breaking

• #2012: Bumped the fuel-vm to 0.55.0 release. More about the change here.
• #2001: Prevent GraphQL query body to be huge and cause OOM. The default body size is 1MB. The limit can be changed by the graphql-request-body-bytes-limit CLI argument.
• #1991: Prepare the database to use different types than Database for atomic view.
• #1989: Extract HistoricalView trait from the AtomicView.
• #1676: New fuel-core-client is incompatible with the old fuel-core because of two requested new fields.
• #1676: Changed default value for api-request-timeout to be 30s.
• #1676: Now, GraphQL API has complexity and depth limitations on the queries. The default complexity limit is 20000. It is ~50 blocks per request with transaction IDs and ~2-5 full blocks.

Fixed

• #2000: Use correct query name in metrics for aliased queries.
