Apache...::File(3pm)

💾 Apache...::File(3pm) — the manual, but make it cute

okay bestie, sit down, hydrate, and let me tell you about Apache::Session::Store::File — a Perl module that lives in the User Contributed Perl Documentation section and exists for exactly one glorious reason: putting your session data on the filesystem. no cap. 🎀

---

✨ NAME ✨

Apache::Session::Store::File — store persistent data on the filesystem 💅

like. the whole job. persistent data. filesystem. iconic.

---

🌸 SYNOPSIS 🌸

here's the vibe, verbatim, don't touch it:

use Apache::Session::Store::File;

my $store = Apache::Session::Store::File->new;

$store->insert($ref);
$store->update($ref);
$store->materialize($ref);
$store->remove($ref);

look at her. four little methods. insert, update, materialize, remove. she's doing the absolute most with the absolute least and I respect it 🫶

---

💖 DESCRIPTION 💖

so this module fulfills the storage interface of Apache::Session — that's its whole personality. it's the friend who shows up, does the thing, and leaves.

and the thing? the serialized objects get stored in files on your filesystem. that's it. that's the tea. no database, no daemon, no drama — just files, sitting there, being files. ✨

---

👑 OPTIONS 👑

this module needs one argument, in the usual Apache::Session style. one. single. argument. lowkey minimalist queen.

• Directory — the name of the option. the value is the full path of the directory where you want the files to go. full path, bestie, not a vibe, an actual path. 📁

example, and I'm quoting this exactly because it's sacred:

tie %s, 'Apache::Session::File', undef,
   {Directory => '/tmp/sessions'};

see how Directory is pointing at /tmp/sessions? that's where the files go. that's the whole setup. slay.

---

🦋 NOTES 🦋

okay this is the part where I need you to actually listen because it's giving important.

All session objects are stored in the same directory. every single one. one directory, all the files, no subfolders, no mercy.

and here's why that matters: some filesystems — like Linux's ext2fs — have O(n) performance where n is the number of files in a directory. so the more files you pile in, the slower it gets. it's giving "line at the boba shop at 3pm" energy. 😭

other filesystems, like Sun's UFS and Linux's reiserfs, do not have this problem. they're built different fr fr.

so before you use this module to store many objects — like, a lot a lot — you should consider your filesystem's performance. do your research bestie, don't come crying to me when your directory has 400,000 files in it 💀

🍓 the sign-off 🍓

that's the whole page, bestie! this doc came to you from perl v5.36.0, dated 2022-11-19, filed under the manual name Apache...::File(3pm) in the User Contributed Perl Documentation. go forth, store your files, check your filesystem's performance, and remember: same directory for everyone, periodt. 💅✨🎀
