Release v0.42.0

[xgreenx]

Version 0.42.0

Breaking

• 2648: Add feature-flagged field to block header fault_proving_header that contains a commitment to all transaction ids.
• 2678: Removed public accessors for BlockHeader fields and replaced with methods instead, moved tx_id_commitment to the application header of BlockHeaderV2.
• 2746: Breaking changes to the CLI arguments:
  • To disable random-walk just don't specify it. Before it required to use --random-walk 0.
  • Next CLI arguments were renamed:
    • relayer-min-duration-s -> relayer-min-duration
    • relayer-eth-sync-call-freq-s -> relayer-eth-sync-call-freq
    • relayer-eth-sync-log-freq-s -> relayer-eth-sync-log-freq
  • Default value for the heartbeat-idle-duration was changed from 1s to 100ms. So information about new block will be propagated faster by default.
  • All CLI arguments below use time(like 100ms, 1s, 1d, etc.) use as a flag argument instead of number of seconds:
    • random-walk
    • connection-idle-timeout
    • info-interval
    • identify-interval
    • request-timeout
    • connection-keep-alive
    • heartbeat-send-duration
    • heartbeat-idle-duration
    • heartbeat-check-interval
    • heartbeat-max-avg-interval
    • heartbeat-max-time-since-last
    • relayer-min-duration
    • relayer-eth-sync-call-freq
    • relayer-eth-sync-log-freq
• 2840: CLI argument vm-backtrace is deprecated and does nothing. It will be removed in a future version of fuel-core.
  The extra_tx_checks field was renamed into forbid_fake_coins that affects JSON based serialization/deserialization.
  Renamed extra_tx_checks_default field into forbid_fake_coins_default.

Added

• 2150: Upgraded libp2p to 0.54.1 and introduced ConnectionLimiter to limit pending incoming/outgoing connections.

• 2491: Storage read replays of historical blocks for execution tracing. Only available behind --historical-execution flag.

• 2619: Add possibility to submit list of changes to rocksdb.

• 2666: Added two new CLI arguments to control the GraphQL queries consistency: --graphql-block-height-tolerance (default: 10) and --graphql-block-height-min-timeout (default: 30s). If a request requires a specific block height and the node is slightly behind, it will wait instead of failing.

• 2682: Added GraphQL APIs to get contract storage and balances for current and past blocks.

• 2719: Merklized DA compression temporal registry tables.

• 2722: Service definition for state root service.

• 2724: Explicit error type for merkleized storage.

• 2726: Add a new gossip-sub message for transaction preconfirmations

• 2731: Include TemporalRegistry trait implementations for v2 tables.

• 2733: Add a pending pool transaction that allow transaction to wait a bit of time if an input is missing instead of direct delete.

• 2742: Added API crate for merkle root service.

• 2756: Add new service for managing pre-confirmations

• 2769: Added a new assembleTx GraphQL endpoint. The endpoint can be used to assemble the transaction based on the provided requirements.

  • The returned transaction contains:

    • Input coins to cover required_balances
    • Input coins to cover the fee of the transaction based on the gas price from block_horizon
    • Change or Destroy outputs for all assets from the inputs
    • Variable outputs in the case they are required during the execution
    • Contract inputs and outputs in the case they are required during the execution
    • Reserved witness slots for signed coins filled with 64 zeroes
    • Set script gas limit(unless script is empty)
    • Estimated predicates, if estimate_predicates == true

  • Returns an error if:

    • The number of required balances exceeds the maximum number of inputs allowed.
    • The fee address index is out of bounds.
    • The same asset has multiple change policies(either the receiver of
      the change is different, or one of the policies states about the destruction
      of the token while the other does not). The Change output from the transaction
      also count as a ChangePolicy.
    • The number of excluded coin IDs exceeds the maximum number of inputs allowed.
    • Required assets have multiple entries.
    • If accounts don't have sufficient amounts to cover the transaction requirements in assets.
    • If a constructed transaction breaks the rules defined by consensus parameters.

• 2780: Add implementations for the pre-confirmation signing task

• 2784: Integrate the pre conf signature task into the main consensus task

• 2788: Scaffold dedicated compression service.

• 2799: Add a transaction waiter to the executor to wait for potential new transactions inside the block production window.
  Add a channel to send preconfirmation created by executor to the other modules
  Added a new CLI arguments:

  • --production-timeout to control the block production timeout in the case if block producer stuck.
  • --poa-open-period set the block production mode to Open. The Open mode starts the production of the next block immediately after the previous block. The block is open until the period passed. The period is a duration represented by 100ms, 1s, 1m, etc. The manual block production is disabled if this production mode is used.

• 2802: Add a new cache with outputs extracted from the pool for the duration of the block.

• 2824: Introduce new Try-like methods for the TaskNextAction

• 2840: Added a new CLI arguments:

  • assemble-tx-dry-run-limit - The max number how many times script can be executed during assemble_tx GraphQL request. Default value is 3 times.
  • assemble-tx-estimate-predicates-limit - The max number how many times predicates can be estimated during assemble_tx GraphQL request. Default values is 10 times.

• 2841: Following endpoints allow estimation of predicates on submission of the transaction via new estimatePredicates argument:

  • submit
  • submit_and_await
  • submit_and_await_status

  The change is backward compatible with all SDKs. The change is not forward-compatible with Rust SDK in the case of the estiamte_predicates flag set.

• 2844: Implement DA compression in fuel-core-compression-service.

• 2845: New status to manage the pre confirmation status send in TxUpdateSender.

• 2855: Add an expiration interval check for pending pool and refactor extracted_outputs to not rely on block creation/process sequence.

• 2856: Add generic logic for managing the signatures and delegate keys for pre-confirmations signatures

• 2862: Derive enum_iterator::Sequence and strum_macros::{EnumCount, IntoStaticStr} for MerkleizedColumn.

Changed

• 2388: Rework the P2P service codecs to avoid unnecessary coupling between components. The refactoring makes it explicit that the Gossipsub and RequestResponse codecs only share encoding/decoding functionalities from the Postcard codec. It also makes handling Gossipsub and RequestResponse messages completely independent of each other.
• 2460: The type of the max_response_sizefor the postcard codec used in RequestResponse protocols has been changed from usize to u64.
• 2473: Graphql requests and responses make use of a new extensions object to specify request/response metadata. A request extensions object can contain an integer-valued required_fuel_block_height field. When specified, the request will return an error unless the node's current fuel block height is at least the value specified in the required_fuel_block_height field. All graphql responses now contain an integer-valued current_fuel_block_height field in the extensions object, which contains the block height of the last block processed by the node.
• 2618: Parallelize block/transaction changes creation in Importer
• 2653: Added cleaner error for wasm-executor upon failed deserialization.
• 2656: Migrate test helper function create_contract to fuel_core_types::test_helpers::create_contract, and refactor test in proof_system/global_merkle_root crate to use this function.
• 2659: Replace derivative crate with educe crate.
• 2705: Update the default value for --max-block-size and --max-transmit-size to 50 MB
• 2715: Each GraphQL response contains current_consensus_parameters_version and current_stf_version in the extensions section.
• 2723: Change the way we are building the changelog to avoids conflicts.
• 2725: New txpool worker to remove lock contention
• 2752: Extended the TransactionStatus to support pre-confirmations.
• 2761: Renamed ConsensusParametersProvider to ChainStateInfoProvider because it is now providing more than just info about consensus parameters.
• 2767: Updated fuel-vm to v0.60.0, see release notes.
• 2781: Deprecate dryRun mutation. Use dryRun query instead.
• 2791: Added TxStatusManager service which serves as a single source of truth regarding the current statuses of transactions
• 2793: Moved common merkle storage trait implementations to fuel-core-storage and made it easier to setup a set of columns that need merkleization.
• 2799: Change the block production to not be trigger after an interval but directly after the creation of last block and let the executor run for the block time window.
• 2800: Implement P2P adapter for preconfirmation broadcasting
• 2802: Change new txs notifier to be notified only on executable transactions
• 2811: When the state rewind window of 7d was triggered, the is_migration_in_progress was repeatedly called, resulting in multiple iterations over the empty ModificationsHistoryV1 table. Iteration was slow because compaction didn't have a chance to clean up V1 table. We removed iteration from the migration process.
• 2824: Improve conditions where Errors in the PreConfirmationSignatureTask stop the service
• 2840: Removed log_backtrace logic from the executor. It is not needed anymore with the existence of the local debugger for the transactions.
• 2865: Consider the following transaction statuses as final: Success, Failure, SqueezedOut, PreConfirmationSqueezedOut. All other statuses will be considered transient.

Fixed

• 2646: Improved performance of fetching block height by caching it when the view is created.
• 2682: Fixed the issue with RPC consistency feature for the subscriptions(without the fix first we perform the logic of the query, and only after verify the required height).
• 2730: Fixed RocksDB closing issue that potentially could panic.
• 2743: Allow discovery of the peers when slots for functional connections are consumed. Reserved nodes are not affected by the limitation on connections anymore.
• 2746: Fixed flaky part in the e2e tests and version compatibility tests. Speed up compatibility tests execution time. Decreased the default time between block height propagation throw the network.
• 2758: Made tx_id_commitment feature flagged in fuel-core-client.
• 2832: - Trigger block production only when all other sub services are started.
  • Fix relayer syncing issue causing block production to slow down occasionally.
• 2840: Fixed fuel-core-client receipt deserialization in the case if the ContractId is zero.

Removed

• 2863: Removed everything related to the state root service, as it has been moved to another repo.
