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 domains. Every individual repair commands is executed transactionally, i.e., either all its effects are applied or none. This is achieved in the same way as for request processing:

If anything goes wrong before advancing the clean request prehead, the already persisted data will be cleaned up upon the next repair request or reconnection to the domain.

  4. def addContracts(domain: DomainAlias, 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 domain in an offline fashion.

    Participant repair utility for manually adding contracts to a domain in an offline fashion.

    domain

    alias of domain to add contracts to. The domain 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 domain. 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)

  8. def changeDomain(contractIds: Seq[LfContractId], sourceDomainId: DomainId, targetDomainId: DomainId, skipInactive: Boolean, batchSize: PositiveInt)(implicit traceContext: TraceContext): EitherT[Future, String, Unit]

    Change the association of a contract from one domain to another

    Change the association of a contract from one domain to another

    This function here allows us to manually insert a transfer out / in into the respective journals in order to move a contract from one domain 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.

    skipInactive

    if true, then the migration will skip contracts in the contractId list that are inactive

  9. def changeDomainAwait(contractIds: Seq[LfContractId], sourceDomain: DomainAlias, targetDomain: DomainAlias, skipInactive: Boolean, batchSize: PositiveInt)(implicit traceContext: TraceContext): Either[String, Unit]

    Participant repair utility for manually moving contracts from a source domain to a target domain in an offline fashion.

    Participant repair utility for manually moving contracts from a source domain to a target domain in an offline fashion.

    contractIds

    ids of contracts to move that reside in the sourceDomain

    sourceDomain

    alias of source domain from which to move contracts

    targetDomain

    alias of target domain to which to move contracts

    skipInactive

    whether to only move contracts that are active in the source domain

    batchSize

    how big the batches should be used during the migration

    Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed.

    Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed. This allows proper clean up of stray promises when the node is transitioning to a passive state.

    Note: you should *not* invoke success on the returned promise but rather use trySuccess. The reason is that the call to success may fail in case of shutdown.

    Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

    DO NOT CALL this.close as part of f, because it will result in a deadlock.
