[rabbitmq-discuss] getting duplicated delivery

[Billy Hand]

Well I should add that I'm using PHP and the PECL bindings for the
rabbitmq-c library.  So I've been able to determine the exact repro steps.
1. get (no_ack off)
2. ack
3. get again, the connection drops, the message gets redelivered

The exact same code connecting to rabbitmq 3.0.4 does not have this problem
so I'm guessing something broke with the PHP bindings or rabbitmq-c between
versions.  I leave room for a misconfiguration of rabbitmq on my part but
other than setting up a user/password and giving it full access to the /
vhost I didn't do much configuration on either.  Here is the code I'm using:

Producer:
<?php

$co = new AMQPConnection();
$co->setLogin('user');
$co->setPassword('password');
$co->setTimeout(60);
$co->connect();

$ch = new AMQPChannel($co);

$ex_name = 'test_exchange';
$ex = new AMQPExchange($ch);
$ex->setName($ex_name);
$ex->setType(AMQP_EX_TYPE_DIRECT);
$ex->declare();

$q_name = 'test_queue';
$q = new AMQPQueue($ch);
$q->setName($q_name);
$q->setFlags(AMQP_DURABLE);
$q->declare();
$q->bind($ex_name, $q_name);

$ex->publish('test_message'.microtime(true), $q_name);

Consumer:
<?php

$co = new AMQPConnection();
$co->setLogin('user');
$co->setPassword('password');
$co->setTimeout(0);
$co->connect();

$ch = new AMQPChannel($co);

$ex_name = 'test_exchange';
$ex = new AMQPExchange($ch);
$ex->setName($ex_name);
$ex->setType(AMQP_EX_TYPE_DIRECT);
$ex->declare();

$q_name = 'test_queue';
$q = new AMQPQueue($ch);
$q->setName($q_name);
$q->setFlags(AMQP_DURABLE);
$q->declare();
$q->bind($ex_name, $q_name);

while (true) {
  //$envelope = $q->get(AMQP_AUTOACK);
  $envelope = $q->get();
  if ($envelope) {
    echo $envelope->getBody() ."\n";
    $q->ack($envelope->getDeliveryTag());
    $envelope = false;
  }
}
