Predis transactions not supported?

[tarjei]

Hi, I thought Predis transactions were supported - is that not correct?

Here's the code I was trying to test:

function fetchMessages($redisClient) {
        $messages = $redisClient->zrevrangebyscore('myqueue', time(), 0);
        $queueId = 'myqueue';

        foreach ($messages as $message) {
            $dmes = json_decode($message, true);
            $redisClient->transaction(
                function ($tx) use ($dmes, $queueId, $message) {
                    $tx->zrem($queueId, $message);
                    $tx->rpush($dmes['destination'], json_encode($dmes['message']));
                }
            );
        }

}

And the test:

function testMyRedisQueue() {
$factory = new \M6Web\Component\RedisMock\RedisMockFactory();
        $redis = $factory->getAdapter('Predis\Client', true, false, '', [
           [ 'profile' => '3.0']
        ]);

  $message = json_encode(['destination'=>'tq1', 'message' => ['key' => 'v'], 'timestamp' =>  new \DateTimeImmutable('now - 3 hours')->getTimestamp()]);
        $redis->zadd('myqueue',  \DateTimeImmutable('now - 3 hours')->getTimestamp(), $message);

        $this->assertEquals(0, $redis->llen('tq1'));

       fetchMessages($redis); 
  
       $this->assertEquals(1, $this->redis->llen('tq1'));

}

I have isolated the problem to the code within the transaction call. If I run it outside the transaction then the test works. Any ideas on how to fix this?

Hey @tarjei , indeed, transaction aren't supported in RedisMock. Feel free to propose something if you want to improve.

OK, I thought this sentence in the readme would let me test the transaction code: 'It mocks *MULTI*, *DISCARD* and *EXEC* commands but without any transaction behaviors, they just make the interface fluent and return each command results. *PIPELINE* and *EXECUTE* pseudo commands (client pipelining) are also mocked.'

I didn't expect a transaction, just that the commands happened. Den tir. 30. okt. 2018 kl. 15:17 skrev Tarjei Huse <tarjei.huse@gmail.com>:
