Expand description

Messages received by the Validation subsystem.

Validation Requests

Validation requests made to the subsystem should return an error only on internal error. Otherwise, they should return either Ok(ValidationResult::Valid(_)) or Ok(ValidationResult::Invalid).

Variants

ValidateFromChainState(CandidateDescriptor, Arc<PoV>, Duration, Sender<Result<ValidationResult, ValidationFailed>>)

Validate a candidate with provided parameters using relay-chain state.

This will implicitly attempt to gather the PersistedValidationData and ValidationCode from the runtime API of the chain, based on the relay_parent of the CandidateDescriptor.

This will also perform checking of validation outputs against the acceptance criteria.

If there is no state available which can provide this data or the core for the para is not free at the relay-parent, an error is returned.

ValidateFromExhaustive(PersistedValidationData, ValidationCode, CandidateDescriptor, Arc<PoV>, Duration, Sender<Result<ValidationResult, ValidationFailed>>)

Validate a candidate with provided, exhaustive parameters for validation.

Explicitly provide the PersistedValidationData and ValidationCode so this can do full validation without needing to access the state of the relay-chain.

This request doesn’t involve acceptance criteria checking, therefore only useful for the cases where the validity of the candidate is established. This is the case for the typical use-case: secondary checkers would use this request relying on the full prior checks performed by the relay-chain.
