Pt-archiver plugin error

I want to create a plugin for pt-archiver and I can’t seem to get it working.

These are the relevant versions:

$ pt-archiver --version
pt-archiver 3.6.0

$ perl --version
This is perl 5, version 38, subversion 2 (v5.38.2)

This is the pt-archiver command without any plugins and it works just fine.

$ /opt/homebrew/bin/pt-archiver
–source h=127.0.0.1,D=sb1,t=t1,u=root,p=test
–progress=500
–where=“1=1”
–primary-key-only
–purge

Then I copied/pasted the plugin from the documentation found here and saved it as /tmp/test_plugin.pm.

package test_plugin;

sub new {
my ( $class, %args ) = @_;
return bless(%args, $class);
}

sub before_begin {
my ( $self, %args ) = @_;
$self->{cols} = $args{cols};
}

sub is_archivable {
my ( $self, %args ) = @_;
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;

Then I added the plugin parameter to the pt-archiver like this:

/opt/homebrew/bin/pt-archiver
–source h=127.0.0.1,D=sb1,t=t1,u=root,p=test
–progress=500
–where=“1=1”
–primary-key-only
–purge
–plugin=test_plugin.pm

And when I run it with PTDEBUG=1, I get this error:

Bareword “test_plugin.pm” not allowed while “strict subs” in use at (eval 34) line 1.

What am I doing wrong here? Can anyone give some pointers on what I can try to debug this issue?

The docs say:

Specify the Perl module name

In your example, you are specifying the filename (test_plugin.pm). Try specifying only the module name.

So I tried this:

$ /opt/homebrew/bin/pt-archiver
–source h=127.0.0.1,D=sb1,t=t1,u=root,p=test
–progress=500
–where=“1=1”
–primary-key-only
–purge
–plugin=“test_plugin”

Bareword “test_plugin.pm” not allowed while “strict subs” in use at (eval 34) line 1.

It is the same error though.

Actually, if I specify m=test_plugin instead of using --plugin option, it actually works. I just need to make sure that test_plugin.pm is in the proper path that pt-archiver can find.
