Bug #59877 [Opn->Csd]: AMQP_NOACK on AMQPQueue::get not respected

Edit report at https://bugs.php.net/bug.php?id=59877&edit=1 ID: 59877 Updated by: pdezwart@php.net Reported by: luke at lukelanchester dot com Summary: AMQP_NOACK on AMQPQueue::get not respected -Status: Open +Status: Closed Type: Bug Package: amqp Operating System: OS X 10.6.2 PHP Version: 5.3.2 -Assigned To: +Assigned To: pdezwart Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is actually the expected behavior. Providing the AMQP_NOACK flag indicates that you will not be ack'ing the message, and that the server should instead ack it as soon as it sends it off to the client. Unfortunately, there is a bug in that you cannot get/consume without acking. This will be fixed in trunk shortly and be part of the 0.4.* release. Previous Comments: ------------------------------------------------------------------------ [2011-10-11 06:13:42] php at aotd dot ru It's not a bug, but normal situation. $q->get(AMQP_NOACK) set NOACK flag for message and it _skipped_ by next get() commands. When you disconnect all unacknowledged messages drop this flag and can be fetched by get() again. ------------------------------------------------------------------------ [2011-09-28 04:43:53] qwaser at gmail dot com Confirmed on PHP 5.3.5 and amqp 0.3.1 ------------------------------------------------------------------------ [2011-08-01 07:33:43] luke at lukelanchester dot com Description: ------------ When using AMQPQueue to read messages, it reads messages correctly. However, using the AMQP_NOACK flag seems to have no effect as messages are still being acknowledged. It appears others have experienced this as well (search StackOverflow). Reproduce code: --------------- <?php // Example borrowed from http://www.php.net/manual/en/amqp.examples.php#104117 $exchangeName = 'myexchange'; $routingKey = 'routing.key'; $queueName = 'myqueue'; // connect $connection = new AMQPConnection(); $connection->connect(); // setup our queue $q = new AMQPQueue($connection); $q->declare($queueName); // Bind it on the exchange to routing.key $q->bind($exchangeName, $routingKey); // show the message print_r($q->get(AMQP_NOACK)); // Should return same message in theory print_r($q->get(AMQP_NOACK)); $connection->disconnect(); Expected result: ---------------- Same message returned as previous get() not acknowledged Actual result: -------------- The next message in the queue and queue count decremented by 1. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=59877&edit=1
