AEROSPIKE_ERR_RECORD_NOT_FOUND after refresh or redirect.

[paulm17]

Hi,

I am having issues where I set a record and after I do a redirect or refresh, then I see in the logs:

Error 2 : AEROSPIKE_ERR_RECORD_NOT_FOUND : Array\n(\n    [ns] => sessions\n    [set] => session\n    [key] => session_9c7b3414346b04e489a88a25a4328b67\n)\n

My code for generating my own session:

public function set_click_session($session_data)
{
    $uniq_id = $this->gen_session_id();

    $as_data = array(
        'bin' => 'sessions',
        'table' => 'session',
        'key' => "session_" . $uniq_id
    );

    $this->aerospike_funcs->set($as_data, $session_data);
}

public function get_click_session()
{
    $uniq_id = $this->gen_session_id();

    $as_data = array(
        'bin' => 'sessions',
        'table' => 'session',
        'key' => "session_" . $uniq_id
    );

    return $this->aerospike_funcs->get($as_data);
}

private function gen_session_id()
{
    // Create unique id for decoding
    $id = ip2long($this->input_funcs->ip_address()) . '#' . $this->input_funcs->user_agent();
    $uniq_id = md5($id);

    return $uniq_id;
}

My code for the aerospike functionality:

<?php

class aerospike_funcs
{
    public function __construct()
    {
        $this->app = \Slim\Slim::getInstance();
        $this->db = $this->app->aerospike_db;
    }

    public function reset_id()
    {
        $id = $this->db->initKey('writes', 'sub_id', 'id');
        $this->db->remove($id);

        $id = $this->db->initKey('writes', 'click_id', 'id');
        $this->db->remove($id);
    }

    public function increment_id($type)
    {
        $key = $this->db->initKey('writes', $type, 'id');

        $op = [
            ['bin' => 'id', 'val' => 1, 'op' => Aerospike::OPERATOR_INCR],
            ['bin' => 'id', 'op' => Aerospike::OPERATOR_READ]];

        $status = $this->db->operate($key, $op, $r);

        if ($status == 0)
        {
            return $r['id'];
        }
        else
        {
            error_log("writes - " . $type . " - id");
            error_log("Error ". $this->db->errorno() . " : " . $this->db->error());
            die();
        }
    }

    public function get($data)
    {
        $id = $this->db->initKey($data['bin'], $data['table'], $data['key']);
        $status = $this->db->get($id, $record);

        if ($status == Aerospike::OK)
        {
            $record = $record['bins'];

            return $record;
        }
        else
        {
            // Log
            error_log($data['bin'] . " - " . $data['table'] . " - " . $data['key']);
            error_log("Error ". $this->db->errorno() . " : " . $this->db->error() . " : " . print_r ($id, true));
            return false;
        }
    }

    public function set($data, $record)
    {
        $id =  $this->db->initKey($data['bin'], $data['table'], $data['key']);
        $status = $this->db->put($id, $record);

        if ($status != Aerospike::OK)
        {
            // Log
            error_log($data['bin'] . " - " . $data['table'] . " - " . $data['key']);
            error_log("Error ". $this->db->errorno() . " : " . $this->db->error() . "\n");
        }
    }

    public function delete($data)
    {
        $id = $this->db->initKey($data['bin'], $data['table'], $data['key']);

        $this->db->remove($id);
    }
}

Here is my aerospike conf:

I've seen a few times now in the logs:

Aug 31 2015 18:00:06 GMT: WARNING (rw): (thr_rw.c::3233) unusual - setting generation 0<Digest>:0x4203052e5a17092669b030d2e7a43b2453fbf6eb

I presume when trying to write the session object?

I also see this too:

After I have written data to aerospike:

Aug 31 2015 18:02:10 GMT: INFO (info): (thr_info.c::4885) namespace sessions: disk inuse: 1920 memory inuse: 64 (bytes) sindex memory inuse: 0 (bytes) avail pct 99 cache-read pct 100.00

After just a few minutes:

Aug 31 2015 18:06:00 GMT: INFO (info): (thr_info.c::4885) namespace sessions: disk inuse: 0 memory inuse: 0 (bytes) sindex memory inuse: 0 (bytes) avail pct 99 cache-read pct 0.00

Now the file sizes are zero? Misconfiguration on aerospike configuration?
