publishPublicSigningKeyLocked method

Future publishPublicSigningKeyLocked({ String? value, })

publishPublicSigningKey without taking the lock, for a caller that already holds it. Taking it twice from one call chain would deadlock: the second acquire waits on a chain entry only the first can complete.

Implementation

Future publishPublicSigningKeyLocked({String? value}) async {
  value ??= await publicSigningKeyValue;

  String? published;
  try {
    logger.finer('publishPublicSigningKey: checking $publicSigningKeyUri');
    final current = await atClient.get(
      AtKey.fromString(publicSigningKeyUri),
      getRequestOptions: GetRequestOptions()..useRemoteAtServer = true,
    );
    published = current.value is String ? current.value as String : null;
  } on AtKeyNotFoundException catch (err) {
    logger.info('${err.message} - publishing now');
  }

  if (published == value) {
    logger.finer('publishPublicSigningKey: have already published');
    return;
  }
  if (published != null) {
    logger.info('publishPublicSigningKey: what is published is not what this '
        'client holds - republishing');
  }
  await atClient.put(
    AtKey.fromString(publicSigningKeyUri),
    value,
    putRequestOptions: PutRequestOptions()..useRemoteAtServer = true,
  );
}
