Devel::GlobalDestruction(3pm)
NAME
Devel::GlobalDestruction - Expose PL_dirty, the flag which marks global
destruction.
SYNOPSIS
package Foo;
use Devel::GlobalDestruction;
use namespace::clean; # to avoid having an "in_global_destruction" method
sub DESTROY {
return if in_global_destruction;
do_something_a_little_tricky();
}
DESCRIPTION
Perl's global destruction is a little tricky to deal with WRT
finalizers because it's not ordered and objects can sometimes
disappear.
Writing defensive destructors is hard and annoying, and usually if
global destruction is happenning you only need the destructors that
free up non process local resources to actually execute.
For these constructors you can avoid the mess by simply bailing out if
global destruction is in effect.
EXPORTS
This module uses Sub::Exporter so the exports may be renamed, aliased,
etc.
