File::...orking(3pm)

hey bestie, this is the File::Flock::Forking(3pm) page from User Contributed Perl Documentation, and it's literally here to make File::Flock behave when fork() enters the chat 💅

🎀 NAME 🎀

File::Flock::Forking — adjust File::Flock to handle fork() 🫶

✨ SYNOPSIS ✨

use File::Flock::Forking;
use File::Flock;

🦋 DESCRIPTION 🦋

okay so the whole purpose of File::Flock::Forking is to change the implementation of File::Flock so it handles locking on systems that do not hold locks across calls to fork() 😭

If you're using File::Flock — or any module that uses File::Flock — and your program uses fork(), then you should import File::Flock::Forking before you import File::Flock or any module that uses File::Flock. order matters, bestie 🫶

On most operating systems, File::Flock::Forking does nothing. On Solaris, it changes the behavior of File::Flock to be implemented by File::Flock::Subprocess 🌞

You can also force it to use FIle::Flock::Subprocess — yes, that capital I is literally what the page says, iykyk — by setting:

$ENV{FLOCK_FORKING_USE} = 'subprocess'

Or force it to use File::Flock with:

$ENV{FLOCK_FORKING_USE} = 'flock'
