probeSyncServer method

  1. @override
Future<SyncServerProbe> probeSyncServer(
  1. SyncServerChoice choice
)
override

Dial choice under the wallet's own Tor policy and ask the server who it is (one round trip, 15 s budget). Throws typed — WalletErrorKind.syncServerUnreachable, .networkMismatch, .syncServerNotOffered, .invalidEndpoint (a custom URL the door refuses) — and NEVER switches: the picker's "Check server" step. The switch itself is the provisioner's (WalletProvisioner.switchSyncServer) because it swaps the session.

Implementation

@override
Future<SyncServerProbe> probeSyncServer(SyncServerChoice choice) async {
  probeCount++;
  lastProbedChoice = choice;
  final gate = probeGate;
  if (gate != null) await gate.future;
  if (probeThrows != null) throw probeThrows!;
  return probeResult ?? const SyncServerProbe(tip: 3482911);
}
