final class RepairService extends NamedLogging with FlagCloseable with HasCloseContext
Implements the repair commands. Repair commands work only if the participant has disconnected from the affected synchronizers. Additionally for repair commands, which change the Ledger API events: all synchronizers needs to be disconnected, and the indexer is switched to repair mode. Every individual repair command is executed transactionally, i.e., either all its effects are applied or none. This is achieved by the repair-indexer only changing the Synchronizer Indexes for the affected synchronizers after all previous operations were successful, and the emitted Update events are all persisted. In case of an error during repair, or crash during repair: on node and synchronizer recovery all the changes will be purged. During a repair operation (as synchronizers are disconnected) no new events are visible on the Ledger API, neither the ones added by the ongoing repair. As the repair operation successfully finished new events (if any) will become visible on the Ledger API - Ledger End and synchronizer indexes change, open tailing streams start emitting the repair events if applicable.

- new RepairService(participantId: ParticipantId, syncCrypto: SyncCryptoApiParticipantProvider, packageDependencyResolver: PackageDependencyResolver, contractAuthenticator: ContractAuthenticator, contractStore: Eval[ContractStore], ledgerApiIndexer: Eval[LedgerApiIndexer], aliasManager: SynchronizerAliasManager, parameters: ParticipantNodeParameters, threadsAvailableForWriting: PositiveInt, synchronizerLookup: SynchronizerLookup, executionQueue: SimpleExecutionQueue, loggerFactory: NamedLoggerFactory)(implicit ec: ExecutionContext)
- executionQueue
Sequential execution queue on which repair actions must be run. This queue is shared with the CantonSyncService, which uses it for synchronizer connections. Sharing it ensures that we cannot connect to the synchronizer while a repair action is running and vice versa. It also ensure only one repair runs at a time. This ensures concurrent activity among repair operations does not corrupt state.

- def addContracts(synchronizerAlias: SynchronizerAlias, contracts: Seq[RepairContract], ignoreAlreadyAdded: Boolean, ignoreStakeholderCheck: Boolean, workflowIdPrefix: Option[String] = None)(implicit traceContext: TraceContext): Either[String, Unit]
Participant repair utility for manually adding contracts to a synchronizer in an offline fashion.
Participant repair utility for manually adding contracts to a synchronizer in an offline fashion.
- synchronizerAlias
alias of synchronizer to add contracts to. The synchronizer needs to be configured, but disconnected to prevent race conditions.
- contracts
contracts to add. Relevant pieces of each contract: create-arguments (LfContractInst), template-id (LfContractInst), contractId, ledgerCreateTime, salt (to be added to SerializableContract), and witnesses, SerializableContract.metadata is only validated, but otherwise ignored as stakeholder and signatories can be recomputed from contracts.
- ignoreAlreadyAdded
whether to ignore and skip over contracts already added/present in the synchronizer. Setting this to true (at least on retries) enables writing idempotent repair scripts.
- ignoreStakeholderCheck
do not check for stakeholder presence for the given parties
- workflowIdPrefix
If present, each transaction generated for added contracts will have a workflow ID whose prefix is the one set and the suffix is a sequential number and the number of transactions generated as part of the addition (e.g.
import-foo-1-2,import-foo-2-2)

Change the assignation of a contract from one synchronizer to another
Change the assignation of a contract from one synchronizer to another
This function here allows us to manually insert a unassignment/assignment into the respective journals in order to change the assignation of a contract from one synchronizer to another. The procedure will result in a consistent state if and only if all the counter parties run the same command. Failure to do so, will results in participants reporting errors and possibly break.
- contracts
Contracts whose assignation should be changed. The reassignment counter is by default incremented by one. A non-empty reassignment counter allows to override the default behavior with the provided counter.
- skipInactive
If true, then the migration will skip contracts in the contractId list that are inactive
