Setting predis database parameter not working? about predis

[nrk]

It works as expected here using both Predis v0.6.6 (the current stable release) and v0.7.0-dev (using the most recent commit from the master branch) so I can't reproduce your problem.

How are you verifying that the keys end up in the wrong database?

I was just verifying it manually using the redis-cli. Maybe because I am just plainly running the redis-server from its source directory. I'll try to pass a config file to the redis server and see what happens.

You can verify that Predis is sending the SELECT command with the correct arguments by launching ./redis-cli MONITOR.

Alternatively you can start redis with an empty database and execute the following snippet:

$parameters = array(
    'host'     => '127.0.0.1',
    'port'     => 6379,
    'database' => 15
);

$client = new Predis\Client($parameters);

$client->set("foo", "bar");
$client->select(10);
$client->set("foo", "bar");

$info = $client->info();
echo "DB-0: ", isset($info['db0']) ? 'not empty' : 'empty', "\n";
echo "DB-10: ", isset($info['db10']) ? 'not empty' : 'empty', "\n";
echo "DB-15: ", isset($info['db15']) ? 'not empty' : 'empty', "\n";

If you get the following output then everything is fine:

DB-0: empty
DB-10: not empty
DB-15: not empty

I actually emptied my redis server.

I started redis cli using redis-cli MONITOR

and here is what I got

+1319541819.515487 "MONITOR"
+1319541866.517235 "SELECT" ""
+1319541866.517884 "RPUSH" "queue:item" "item1" 

redis version is 2.0.3-2
php version is 5.3.6
predis version is 0.6.0

Where can I find 0.6.6 or 0.7.0 every time i click this https://github.com/nrk/predis/zipball/master I get 0.6.0

Hmm yeah it looks like this link generates a file named predis-v0.6.0-521-g29f26b0.zip but it really contains v0.7.0-dev as indicated by the VERSION file (it's probably a bug of GitHub, I don't know why). Anyway you could try downloading v0.6.6 from the tags page.

That said, the strange thing is that you should be seeing "SELECT" "15" instead of "SELECT" "" (which means that the client is passing an empty argument to Redis) in the output of your MONITOR session but I really can't understand why it happens since I can't reproduce your problem using the same versions under Ubuntu 11.04 and other combinations on a couple of different virtual machines.

Can you double check the problem by running the same test on a different server / configuration?

So I downloaded 0.6.6 from this link http://github.com/nrk/predis/zipball/v0.6.6 The 0.6.6 doesn't contain an autoloader so I just added the Predis.php file.

I tried to remove the redis snippets out of my class and created a separate file which just contains the push query here is how it looks . This one outputs "SELECT" "15" twice.

redis_push_test.php

    require_once 'predis/RedisClient.php';
    $r = new Predis\Client($remote_single_server);
    //did the select part for a purpose based on what I experienced above on my localhost
    $r->select($remote_single_server['database']);
    $r->rpush("queue:test","queue from remote client");

Here is my RedisClient.php

include_once 'predis/lib/Predis.php';

$single_server = array(
    'host'     => '127.0.0.1',
    'port'     => 6379,
    'database' => 15
);

$remote_single_server = array(
    'host'     => '10.241.54.128',
    'port'     => 6379,
    'database' => 15
);

Here is a class which follows the class template of gearman-manager. This is a gearman worker. I trimmed the code to keep it simple. This one outputs "SELECT" "" once

worker.php

require_once 'predis/RedisClient.php';

class siteAnalyzer 
{
    /**
    * Run method
    * 
    * @param mixed $job
    * @param array $log
    * @return nothing
    */
    public function run($job, &$log) 
    {
        $workload = json_decode($job->workload(),true);
        $page = $workload;

        $r = new Predis\Client($remote_single_server);
        $r->select($remote_single_server['database']);

        $r->rpush("queue:test","query here");       

        return json_encode(true);

    }
}

EDITED: Typographical errors.

I have resolved this by creating a static class for the configuration file.

If you add a geometry, use this command:
$redis->geoadd('channel', $lon,$lat,'ticket');
