Why do not the session Kohana 3.3?

Question

After updating php from version 4 to 5.5, in Kohana 3.3.3 stopped working session .. When you call: Session :: instance ('database') there is an error: "Error reading session data."

Why is that?

Session_Exception [ 1 ]: Error reading session data.

SYSPATH/classes/Kohana/Session.php [ 324 ]

319             }
320         }
321         catch (Exception $e)
322         {
323             // Error reading the session, usually a corrupt session.
324             throw new Session_Exception('Error reading session data.', NULL, Session_Exception::SESSION_CORRUPT);
325         }
326 
327         if (is_array($data))
328         {
329             // Load the data locally

Answer 1

with php 5.5 need to use the module melancholy, or PDO, instead of mysql, well, or just turn off the output of these errors to index.php

Answer 2

First of all. check session save path at php ini, and catalog permission for save session files. In my case it was /tmp.

Goto /VAR/LOG and check apache errors log.

And then, open SYSPATH/application/bootstrap.php Find

Kohana::init(array(
    'base_url'   => '/',
    'index_file' => FALSE,
    'errors' => TRUE
));

Change to

Kohana::init(array(     'base_url'   => '/',    'index_file' => FALSE,
'errors' => FALSE ));

And You will see the errors form your's php interpreter or apache.

If it didn't helps You.

Find SYSPATH/classes/Kohana/Session.php [ 324 ] and replace it

throw new Session_Exception('Error reading session data.', NULL, Session_Exception::SESSION_CORRUPT);

and replace it to

throw new Session_Exception('Error reading session data.'. " [SID:".$id."(".$this->id()."), name:".$this->_name."][Details: " . $e . "]\n", NULL, Session_Exception::SESSION_CORRUPT);

And you will find out your's error. In My case it was database err.

Answer 3

Add a var_dump($e) inside the catch block in the kohana's Session.php file where the exception is being thrwoed (like in the code you pasted) and you will find the real problem ;)
