Session reverting back to previous state after slow ajax call finishes

Okay guys, thanks a lot for the help. I think I know where I stand now.

This is an open bug. [url="https://bitbucket.org/ellislab/codeigniter-reactor/issue/262/rapid-requests-during-session-updates"]Issue 262[/url]. I have posted a link to WanWizards solution to explicitly write the session when the ajax request has complted.

Hi pickupman, i'm experiencing a different issue to the one described in that bug. The problem I have has no correlation with session update time.

Regardless, I tried WanWizards session library anyway but the problem persists.

Solved it.... finally!

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Session extends CI_Session
{
  
    /**
     * Add or change data in the "userdata" array
     *
     * @access    public
     * @param    mixed
     * @param    string
     * @param    bool    if set to true we will grab the session data from database again
     * @return    void
     */
    function set_userdata($newdata = array(), $newval = '', $get_again = false)
    {
        if($get_again) $this->sess_read(); // just in case the session has been updated elsewhere after the Session library was loaded here
        
        if (is_string($newdata))
        {
            $newdata = array($newdata => $newval);
        }

        if (count($newdata) > 0)
        {
            foreach ($newdata as $key => $val)
            {
                $this->userdata[$key] = $val;
            }
        }

        $this->sess_write();
    }

}

/* End of file MY_Session.php */
/* Location: ./application/libraries/MY_Session.php */

So, I added a third param $get_again, which if set to true will make sure that the session library has the most up to date session info.

Hope this is of some use to someone...

Actually, instead of extending the library I could just do something like this:

Code:

function some_long_call()
    {
        sleep(20);  
    
        $this->session->sess_read();
        $this->session->set_userdata(array('foo' => 'bar'));
    }

This is a cleaner solution for my setup.

EDIT: Actually, this causes errors.

Code:

function some_long_call()
{
    if ( ! $this->input->is_ajax_request())
    {
        $this->session->sess_read();
        $this->session->set_userdata(array('foo' => 'bar'));
    }  
}
