My session driver of choice for CodeIgniter is database. A while ago, I noticed millions of rows in the corresponding database table. That means that garbage collector was not working. I checked config.php for sess_regenerate_destroy, but it was already set to false. It was really weird because the problem seemed to have come out of nowhere – not much ago things were working just fine.

After a short investigation, I found out this was and still is a common problem for those who had upgraded their CodeIgniter version from 2.x to 3.x. Turns out, the later possesses heavy changes for Sessions library. And most importantly – fundamental changes in dealing with garbage: CodeIgniter 3.x relies on PHP's native grabage collector. So, in order to get things working again, we need to configure PHP properly.

The Solution

Today there are three PHP-native settings for dealing with session garbage collector. CodeIgniter's Session library has already taken care of one of them – gc_maxlifetime – so there's no need for an extra touch here. The problem lies within the rest: session.gc_probability and/or session.gc_divisor. These two determine when the garbage collector is running. Here's what php.net says:

session.gc_divisor coupled with session.gc_probability defines the probability that the gc (garbage collection) process is started on every session initialization. The probability is calculated by using gc_probability/gc_divisor, e.g. 1/100 means there is a 1% chance that the GC process starts on each request.

In my case, using ini_get() revealed the following values: 0 and 1000. The equation 0/1000=0 meant there was no chance the garbage collector would even run.

Finally, I solved the problem by using the values officially stated as default and by putting the following lines of PHP code into config/config.php file:

ini_set( 'session.gc_probability',	1 );
ini_set( 'session.gc_divisor',		100 );

Theoretically, this means that the garbage collector usually runs once every 100th request. It's more than enough, but it is up to you whether that causes too many unnecessary hits to database. An alternative solution for heavy-traffic websites could be having a 0% probability on the production site and a Cronjob-based script which removes database rows of the expired sessions.

WIRED's new animated series takes you inside the secretive world of a slightly askew NSA, with the eccentric Agent Topple, played by John Hodgman, and his young hacker protégé, Nicole Winters.

Agent Topple reveals a few tricks of the pre-digital trade when Winters attempts to explain to him how computers work. Agent Topple is Not Impressed.

Nicole finally gets a chance to hack into a personal email, only to find herself in the bowels of Agent Topple's locked messages from the 90s. As imagined, this is unfortunate.

After an urgent alert from the PRISM program followed by a shocking revelation from Nicole, Agent Topple doesn't not panic.

After recently discovering Winters is actually his supervisor, Agent Topple mobilizes the full power of the National Security State to neutralize this inconvenient threat on his own security. All while catching up on his “stories,” also known to many as the illegal surveillance of private citizens in the comfort of their own home. This is surprisingly stimulating.

Nicole strikes back with a hefty dose of new-school espionage, but Topple is not to be outdone. Hint: you can't topple Topple 'cuz Topple don't stopple!

After Nicole debunks Henry's Buzzfeed logic, he must chose between destroying all electronic music or preserving Downton Abbey.

Topple settles into his new role as a cyber-spy, but hold on to your tequila sunrise: a hangover from his swinging '70s past leaves him odd-man-out at the counter-intelligence key party ... until his target conveniently "disappears."

Hot on the trail of a devastating computer virus, Topple and Winters burn the midnight oil. Are the North Koreans sending encrypted telegrams or has Kim Jong-un taken up beat poetry?

Nicole accuses Topple of treason and Topple plays the class card. But do average Americans really want to live in world where elites are held to the same standards? We think not.

Topple’s bravado is put to the test when his old-school spy game gets the green light. Winters busts out her best pep talk, but can Topple get back to his fighting weight? The fate of the world rests on the shoulders of one man—and his mustache.

Agent Topple's mustache does its dirty work, and Nicole brokers a deal for peace. But why is the NSA collecting millions of Instagram brunch photos? And if your waffles have nothing to hide, what are they so worried about?

Agent Topple attempts to get some holiday spirit.
