Plack beer challenge

[morgon]

Hi

after having just wasted another train journey I have had it now.

Evidently (as I keep reading how "everything just works") I need some external input, so I am offering a bait I know you cannot refuse, the one true currency among Perl-hackers:

BEER

I hope this extraordinary measure conveys how desperate I have become...

So here is the challenge:

I want a complete working solution to make a plack-app run as fast-cgi under apache on Linux.

You can use either mod_fastcgi or mod_fcgid but I want a full apache-config, where to put my psgi-file, what to put in the shebang-line etc etc.

Here is the app:

use strict;

return sub {
   return [ 200, ["Content-Type" =>  "text/plain"], ["hi"] ];
}

I am willing to pay the first monk to supply a working solution a large beer at next year's YAPC::Europe.

If you cannot attend the conference I am willing to send a picture of a real bavarian beer to any email-address of the winner's choosing.

Good luck!

Ok.

This is exactly the type of answer I was NOT looking for.

While I believe that your links may contain the answer I have already proven to myself beyond any doubt that I am too stupid to properly understand them...

Here is my app:

#!/home/mh/perl514/bin/plackup -s FCGI --listen /tmp/fcgi.sock --daemo
+nize --nproc 10 

use strict;
use warnings;

return sub {
   return [ 200, ["Content-Type" =>  "text/plain"], ["hi"] ];
}

Started on it's own it actually works - it starts a web-server on port 5000 that delivers the proper result.

But how to make this work in Apache?

I have put this app as "app.psgi" in /usr/lib/cgi-bin and this is my apache-config:

 ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
                AddHandler fcgid-script .psgi
        </Directory>

Now what happens is that when I try point my browser to the plack-app apache I get an internal server error.

The plack-app actually is launched (there is a process visible), but it seems to me that the plack-app and apache cannot communicate as I can see in the error log that fcgid reports a read timeout and the really weird thing is that I have this line in the error log HTTP::Server::PSGI: Accepting connections at http://0:5000

So to me it seems as if Plack is not aware that it runs under apache for some reasons...

The beer is still for grabs...

When the kernel honors a #! line, it only handles up to 1 argument. It certainly isn't portable to put so many options on your #! unless some non-standard method (not the Unix kernel) is doing the exec.
