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
