Bug Description
I was trying to use the custom modules for pt-archiver documented at http://
Using an exact copy/paste of the example module
====Begin paste===
package My::Module;
sub new {
my ( $class, %args ) = @_;
return bless(\%args, $class);
}
sub before_begin {
my ( $self, %args ) = @_;
# Save column names for later
$self->{cols} = $args{cols};
}
sub is_archivable {
my ( $self, %args ) = @_;
# Do some advanced logic with $args{row}
return 1;
}
sub before_delete {} # Take no action
sub before_insert {} # Take no action
sub custom_sth {} # Take no action
sub after_finish {} # Take no action
1;
====End paste===
I attempt to run with:
pt-archiver --source A=utf8,
And am greeted with:
Can't call method "before_begin" without a package or object reference at /usr/bin/
I have a My/Module.pm in Perls @INC paths so it is definitely able to find the file.

Yes, the docs might be inaccurate. There are tests for plugins, but they use single namespaces instead of multiple like My::Plugin. So perhaps multiple don't actually work. What does work, and is a workaround for the moment, is using a single namespace for the package like "package foo" and put that in foo.pm, then m=foo. If @INC has whatever dir foo.pm is in, that should work.
