-------------------------------------
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:
