Apache...NoLock(3pm)

🎀 Apache::Session::MySQL::NoLock 🎀

okay bestie, so this is the User Contributed Perl Documentation page for Apache::Session::MySQL::NoLock — an implementation of Apache::Session::MySQL with no locking. Yes, you read that right. No locking. We'll get to the screaming part in a sec 💀

---

✨ NAME ✨

Apache::Session::MySQL::NoLock — an implementation of Apache::Session::MySQL without locking. That's the whole vibe. That's the whole module. 🫶

---

🌸 SYNOPSIS 🌸

First, bestie, you gotta pull it in:

use Apache::Session::MySQL::NoLock;

#if you want Apache::Session to open new DB handles:

tie %hash, 'Apache::Session::MySQL::NoLock', $id, {
   DataSource => 'dbi:mysql:sessions',
   UserName => $db_user,
   Password => $db_pass,
};

#or, if your handles are already opened:

tie %hash, 'Apache::Session::MySQL::NoLock', $id, {
   Handle => $dbh,
};

Two paths, same destination: either you let Apache::Session open shiny new DB handles for you, or you hand it handles you already opened. Your call, main character. 💅

And if you're trying to configure the non-locking session store in RT (which, ngl, is literally what the author uses this module for), drop this into your RT_SiteConfig.pm module:

Set($WebSessionClass , 'Apache::Session::MySQL::NoLock');

That's it. That's the config. Slay. ✨

---

💖 DESCRIPTION 💖

So here's the tea: this module is an implementation of Apache::Session. It uses the MySQL backing store and the Null locking scheme. That's the combo. 😌

For the full rundown, peep the example above, plus the documentation for Apache::Session::Store::MySQL — that's where the extra details live. iykyk 📚

🚨 WARNING 🚨

okay bestie, sit down, we need to talk. 🫢

This module explicitly DOES NOT DO ANY LOCKING. That is not a typo, that is not a bug, that is the entire personality of this module.

Which means, fr fr: your session data can get overwritten, or stale data can be read by subsequent requests. 😭

And in case that wasn't loud enough:

This CAN CAUSE LARGE PROBLEMS IN YOUR APPLICATION.

like, LARGE large. Capital letters large. Don't say nobody warned you, bestie. 💀
