Devel::GlobalDestruction(3pm) User Contributed Perl Documentation 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.
in_global_destruction
Returns the current value of "PL_dirty".
VERSION CONTROL
