All Implemented Interfaces:: I2CPMessageHandler

class RequestVariableLeaseSetMessageHandlerextends RequestLeaseSetMessageHandler

_ls2Type
_ls2Type.
(package private) static final int
MAX_TRANSIENT_SIGN_RETRIES
Maximum prompt re-runs of a request after a transient signing failure.
(package private) static final long
MIN_LS2_LEASE_TTL_MS
Minimum remaining lifetime required on a lease end relative to the LS2 published timestamp so LeaseSet2.writeHeader() does not reject the set with "LeaseSet expired".
static final String
PROP_LS_TYPE
PROP_LS_TYPE — used for LS2.
(package private) static final long
TRANSIENT_SIGN_RETRY_DELAY_MS
Delay before a transient signing failure is re-run, in ms.

Modifier and Type
Method
Description
(package private) static long
ensurePositiveLs2Expiry(long leaseEnd, long published, long now)
Floor a requested lease end so it remains strictly after both the LS2 published timestamp (second resolution) and the current time, leaving at least RequestLeaseSetMessageHandler.MIN_LS2_LEASE_TTL_MS of validity.
void
handleMessage(I2CPMessage message, I2PSessionImpl session)
Handle an incoming I2CP message.
(package private) static boolean
isSignable(LeaseSet leaseSet)
Whether a LeaseSet can be signed.
(package private) static boolean
isTransientSignFailure(String reason)
Is a signing failure transient — a stale or clock-skewed request the caller can fix with fresh data — rather than a permanent key or configuration error?
void
removeLeaseSet(Destination dest)
Remove the cached lease info for the given destination.
protected boolean
requiresLS2(I2PSessionImpl session)
Do we send a LeaseSet or a LeaseSet2? As of 0.9.69, always use LS2 unless the router doesn't support it
(package private) void
scheduleSignRetry(I2CPMessage message, I2PSessionImpl session, int attempt)
Schedule a prompt re-run of a request whose signing failed transiently.
protected boolean
signLeaseSet(LeaseSet leaseSet, boolean isLS2, I2PSessionImpl session)
Finish creating and signing the new LeaseSet and submitting it to the router.
protected boolean
signLeaseSet(LeaseSet leaseSet, boolean isLS2, I2PSessionImpl session, I2CPMessage message, int attempt)
Finish creating and signing the new LeaseSet and submitting it to the router, with the originating request attached so a transient signing failure can schedule a prompt re-run instead of leaving the router to wait out its 60-second check timeout.
(package private) static String
validateEndpointCount(int endpoints)
Validate an endpoint count for the variable-length handler.
(package private) static String
validateLeaseSetRequest(int endpoints, Date endDate)
Validate a fixed-length LeaseSet request before any state is mutated.
