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:
- A request counter is allocated for the repair request (namely the clean request head) and marked as com.digitalasset.canton.participant.protocol.RequestJournal.RequestState.Pending. The repair request's timestamp is the timestamp where processing starts again upon reconnection to the domain.
- All repair effects are persisted to the stores using the repair request counter.
- The clean request prehead is advanced to the repair request counter. This commits the changes. If multiple domains are involved, transactionality is ensured via the com.digitalasset.canton.resource.TransactionalStoreUpdate mechanism.
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.

- 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)

- 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
- 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. This allows proper clean up of stray promises when the node is transitioning to a passive state.
