Re: [Catalyst] Suddenly Failing with Moose and MOP Errors

Mon, 31 Jan 2011 05:38:53 -0800 

Ok, at least I'm (arguably) not crazy.
Justin Hunter suggested a few specific upgrades, and I'm going through my cpan updates and have found also that there are quite a number of masked versions where there are two separate versions installed, and the older one is masking the newer one. 

I'll give this a try again when I get back form work today.

Thanks for helping confirm and giving me some direction.  I'll let you know.

Don't know about this specific problem, but we just ran into something 
similar -- no upgrades, no changes, but Catalyst suddenly stopped 
loading (DBIx::Class::Schema::connection(): No arguments to 
load_classes). Wound up having to cpanm a bunch of upgrades by hand 
before it started working again.



So apparently our system either is configured for occasional 
cron-based upgrades and we managed to wind up in an unstable state as 
a result (still looking into this)... or black hats were involved.


You might be in a similar situation. :(

    I have reverted to previously-known working versions and am having
    the same problem.

    Any help that anyone can provide would most certainly be
    appreciated.  This sucks.  It's kind of ridiculous too.

    Thanks.

         I've been looking and I can't seem to figure out what's going on.

        I suspect that it was an underlying Perl module that somehow
        blew up, but I'm not sure.

        Can anyone see anything in here that indicates what the
        problem is?

        Thanks.
