No $r = no mod_perl?

So I'm following your advice and going the easy route of apt-get everything.

My original server had this config:
Apache/2.2.11 (Ubuntu) mod_perl/2.0.4 Perl/v5.10.0 Server

And two years later we're at:
Apache/2.2.14 (Ubuntu) mod_perl/2.0.4 Perl/v5.10.1 Server

Is that really the state of two years of progress in apt-get packages,
or did I choose the wrong repository?

And so after copying over configs and startups I'm getting this error:

Can't call method "auth_name" on an undefined value at
/usr/local/share/perl/5.10.1/Apache2/AuthCookieDBI.pm line 284.

Which is: my $auth_name = $r->auth_name;

So the fact that $r is undefined tells me that whatever is running is
NOT running under mod_perl, is this a valid assessment?

Because right now I will have to get into a fight with my sys-admin who
will say it's not working because I didn't configure something
correctly, but my position is if he apt-gets everything and then copies
over the config/startup from the old (working) install then everything
*should* work so he's probably left out something.

Do you see now why I would prefer to work with a PaaS instead of admins,
I don't want to have to deal with this, I just want to write apps.

Thanks!

Tosh

This does sounds like something in the config didn't get copied over. I
believe your stuff runs as registry/perlrun scripts, so that would be
the configuration that's missing.

Maybe you are using the wrong sethandler value for your application, check

http://perl.apache.org/docs/2.0/user/config/config.html#C_GlobalRequest_

If you are using a global $r variable you should specify

SetHandler perl-script

and not

SetHandler modperl

Using the latter you get the $r variable as an argument to your handler-sub.

Re: No $r = no mod_perl? [In reply to]

Do you have a configuration similar to this in httpd.conf:

<Directory /www/domain.com/authcookiedbi>
AuthType Apache2::AuthCookieDBI
AuthName WhatEver
PerlAuthenHandler Apache2::AuthCookieDBI->authenticate
PerlAuthzHandler Apache2::AuthCookieDBI->authorize
require valid-user
# or you can require users:
require user jacob
# You can optionally require groups.
require group system
</Directory>

Re: No $r = no mod_perl? [In reply to]

Sorry, false alarm... I had subclassed Apache2::AuthCookieDBI 2.12 and
had to do things like this:

*Apache2::AuthCookieDBI::_dbi_connect = sub {

since Apache2::AuthCookieDBI wasn't very subclassable, and with the
upgrade to a very nice Apache2::AuthCookieDBI 2.14 my whatever I did up
there broke things.

I guess I owe my admin a beer.
