[GitHub] [pulsar] congbobo184 opened a new issue #10431: [Transaction bug] Transaction cumulativeAck bug.

[GitBox <gi...@apache.org>]

congbobo184 opened a new issue #10431:
URL: https://github.com/apache/pulsar/issues/10431


   example:
   Transaction abort message1, message2 and then clear incomingMessages.
   after incomingMessage  cleared the message3 can add in incomingMessages. This time we cumulativeAck message3 with txn will lose message1 and message2.
   
    
   ```
       @Test
       public void transactionCumulativeAck() throws Exception {
           String topic = NAMESPACE1 + "/txn-timeout";
   
           @Cleanup
           Consumer<String> consumer = pulsarClient.newConsumer(Schema.STRING)
                   .topic(topic)
                   .subscriptionName("test")
                   .subscribe();
   
           @Cleanup
           Producer<String> producer = pulsarClient.newProducer(Schema.STRING)
                   .topic(topic)
                   .sendTimeout(0, TimeUnit.SECONDS)
                   .enableBatching(false)
                   .producerName("txn-timeout")
                   .create();
   
           producer.send("Hello Pulsar one!");
           producer.send("Hello Pulsar two!");
   
           Transaction transaction = pulsarClient
                   .newTransaction()
                   .withTransactionTimeout(3, TimeUnit.SECONDS)
                   .build().get();
   
           Message<String> message = consumer.receive();
   
           System.out.println(message.getValue());
   
           consumer.acknowledgeCumulativeAsync(message.getMessageId(), transaction).get();
   
           transaction.abort();
   
           transaction = pulsarClient
                   .newTransaction()
                   .withTransactionTimeout(3, TimeUnit.SECONDS)
                   .build().get();
           // it may receive Hello Pulsar two!
           Message<String> reReceiveMessage = consumer.receive(2, TimeUnit.SECONDS);
           System.out.println(reReceiveMessage.getValue());
   
       }
   ```
