Enum ForkCrashBehavior 

Source 
pub enum ForkCrashBehavior {
    RecoverOncePerVersion,
    AwaitForkRecovery,
    ReturnError,
}

Variants§

§

RecoverOncePerVersion

On a detected fork, clear the local fork state and re-execute against the canonical certified checkpoint. Recovery only proceeds when (1) the fork was recorded by a different binary version than the one now running — the binary that forked would deterministically fork again, so the node halts until a corrected binary is deployed — and (2) a certified checkpoint covering the forked checkpoint or transaction is verified in the local store — proof that the network already sealed the canonical outcome, so re-deriving cannot equivocate on an undecided result. Forks failing either condition halt the node awaiting a new binary or operator intervention.

§

AwaitForkRecovery

Halt at startup awaiting operator intervention (e.g. supplying canonical checkpoint digests).

§

ReturnError

Return an error instead of halting. This is primarily for testing.
