-------------------------------------

             Summary: Transaction commit fail when m_transactionId integer overflow to negative value
                 Key: GEODE-8874
                 URL: https://issues.apache.org/jira/browse/GEODE-8874
             Project: Geode
          Issue Type: Bug
          Components: native client
            Reporter: Jakov Varenina


When native client increments *m_transactionId* above INT32_MAX(2147483647) then due to memory overflow the *m_transactionId* is set to negative value INT32_MIN(-2147483648). TransactionID (m_transactionId) is  sent to the server as a part of transaction message.

Currently server will interpret any negative value of transactionID (uniqID) as non-transactional traffic. Please notice that getTransactionID() actually retrieves uniqID value that is set by client.

{code:java}
/**
 * checks to see if this thread needs to masquerade as a transactional thread. clients after
 * GFE_66 should be able to start a transaction.
 *
 * @return true if thread should masquerade as a transactional thread.
 */
protected boolean shouldMasqueradeForTx(Message clientMessage,
    ServerConnection serverConnection) {
  return serverConnection.getClientVersion().isNotOlderThan(KnownVersion.GFE_66)
      && clientMessage.getTransactionId() > TXManagerImpl.NOTX; // ---> NOTX is equal -1
}
{code}

After overflow happens all subsequent commit actions from the client are rejected with exception:
