CI session

Does CI 1.7 session library actually work?

I have created my session table (session_id, ip_address, user_agent, last_activity, user_data) and when set userdata with $this->session->set_userdata('logged_user', $username) it stores in the db table fine as serialized string but cannot get it back using $this->session->userdata('logged_user').
I then thought I should call $this->session->userdata('user_data') and deserialize it but still is empty.

I also noticed when a page request is sent (i.e. refresh or going from login page to landing page) a new session is created and stored in db table.
I'd guess that's probably why I never can get my custom userdata session back?
Is this a reported bug in CI 1.7 or is it just me being dum?

Okay after I went back into Session.php in the /system/libraries I noticed the local variables don't take the configs properly from config.php
Having taken out and left default empty config, it works again..
Need to update Session.php to take config.php settings?

If your asking if CI 1.7 Session library works, well all I can say is that it really works. Cause Ive used it somehow for a day haha. Well, I have a certain data that is needed to store in a session, so I used CI session library but I found out that it only hold 4kb of data and is not practical to use it in my application, so I used PHPSession library.

Good day.

Were you storing sessions in the database (new in 1.7) or in a cookie (pre 1.7 behavior)?

Database is capable of handling MUCH more than 4kb of data.
Its the cookies that can't.

I think your session expiration time is not enough long to hold sessions. check $config['sess_expiration'] setting in config.php. and check this too, http://ellislab.com/forums/viewthread/70036/

I can confirm that something's wrong with CI's session lib. We often get kicked out when sending multiple requests at once or random. I'm not sure why...

We have been experiencing random log outs, particularly on some of our more AJAX heavy pages that make multiple requests per second.

The problem occurs if a request is made while another request is causing sess_update() to run. The database gets updated with the new session ID, but sess_read() has already pulled the old session ID from the cookie, which has not yet been updated. sess_read() tries to find the old session ID in the database, fails, and then destroys the session.

This can be recreated by using the database for sessions, setting $config["sess_time_to_update"] very low and making multiple requests.

The quick solution is to set $config["sess_time_to_update"] very high, but that's a bad call for security reasons. A better fix would be for the Session class to keep the old session records around for an additional few seconds before removing them.

CI 1.7.0
Everytime my page refreshes I get a new session.
I don't know if this a bug or what. But so far CI sessions are not working for me.
Anyone else experience this?

I have the same problem as reported in first post.

If I reload my login view I see all session userdata correct but when I redirect to mainpage everything disappear.

If I disable DB session, it works.

Can you detail what local variables do you have changed?

I've been experiencing similar dropped sessions. I am not using the DB solution, but instead session cookie. I am typically allowing a user to set a session/"remember me" for a month. However upon coming back to the site the next day the session_cookie is still there, but the userdata is gone. I've upped the sess_time_to_update to equal the actual cookie expiration. I will report back on that within the next couple of days.
