in thread Chasing up a module dependency issue

use Module::Name 'method_name';

That is what I think the issue is

The code appears to work as a whole, under mod_perl, but it's failing the unit tests (that have finally been added to the code recently :)

What I'm trying to work out is what exactly would cause the wiping out of the @EXPORT_OK. I thought that was scoped to the current package? Or is the error indicative of another issue?

I really don't want to have to comb through the entire code base, if avoidable. On a hunch, I tried to switch @EXPORT_OK to @EXPORT, but that doesn't appear to have done anything = though mayne I need to look in the spiderweb of module includes and tweak all instances for it to work?

    What you describe shouldn't happen, for the reasons you describe as well. Maybe the unit tests do something weird, or maybe you use use_ok, which can fail (for example due to a syntax error) but the test script itself will continue with a half-compiled module. I fear that this is not really debuggable from afar and mostly tied to your specific source code situation at work...

    Maybe putting a callback into @INC allows you to debug what modules get loaded when, to narrow down the files after which problematic things happen:

    push @INC, sub { print "Loading @_\n"; return () };

    Maybe one of the modules contains a (second) package declaration that matches one found earlier and overwrites something in another package?

      It's only used in two places - I think I'm just going to remove Exporter completely (I hate imported methods anyway, heh).

      The scales that weigh up the balance of how interesting it would be to fully understand and getting on with my day are heavily swaying to the latter ;-)
