NAME
Plack::App::Apache::ActionWrapper - Wrapper for Apache2 Action directive
for running PSGI apps on shared hosting with FastCGI
VERSION
version 0.30.1
SYNOPSIS
------------- .htaccess -----------------
AddHandler fcgid-script .fcgi
# Enable this instead if server is using mod_fastcgi instead of mod_fcgid
#AddHandler fastcgi-script .fcgi
Action psgi-script /cgi-bin/psgi.fcgi
AddHandler psgi-script .psgi
DirectoryIndex index.psgi
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.psgi/$1 [QSA,L]
------------- psgi.fcgi -----------------
#!/usr/bin/env perl
use strict;
use warnings;
# Change this line if you use local::lib or need
# specific libraries loaded for your application
use lib '/home/robin/perl5/lib/perl5';
use Plack::App::Apache::ActionWrapper;
my $app = Plack::App::Apache::ActionWrapper->new->enable_debug->to_app;
# Run the actual app
use Plack::Handler::FCGI;
Plack::Handler::FCGI->new->run($app);
1;
------------- index.psgi -----------------
#!/usr/bin/env plackup
use strict;
use warnings;
my $app = sub {
my $env = shift;
return [
200,
[ 'Content-Type' => 'text/plain' ],
[
"This is the index.\n",
'PATH_INFO=' . $env->{'PATH_INFO'} . "\n",
'PATH_TRANSLATED=' . $env->{'PATH_TRANSLATED'} . "\n",
],
];
};
DESCRIPTION
The PSGI web application specification is awesome. Plack is awesome as
well. Running PSGI apps using plackup in development is super easy.
But what do you do when you want to deploy your PSGI app on shared
hosting? You can deploy it using traditional CGI, but if you're dealing
with something like Moose or Catalyst-based apps it's bound to be slow.
So your shared hosting provider has provided you with FastCGI support to
mitigate that problem. But because FastCGIExternalServer cannot be
defined in .htaccess you can only run dynamic FastCGI applications.
Your immediate reaction is to define "AddHandler fcgid-script .psgi" in
your .htaccess and use plackup on the shebang line to run your PSGI app.
But that doesn't work if you use local::lib, because @INC is not setup
properly.
By using a wrapper as specified in the synopsis you can avoid having to
type in "use lib 'XXX'" in every one of your .psgi files. Another
benefit is that you can preload modules to benefit from copy-on-write on
operating systems that provide it to diminish the memory usage.
METHODS
call
The main handler that will be returned by the "to_app" method inherited
from Plack::Component.
enable_debug
Mutator to enable debug output if no path was found in PATH_TRANSLATED.
Allows chaining.
disable_debug
Mutator to disable debug output if no path was found in PATH_TRANSLATED.
Allows chaining.
is_debug_enabled
Accessor to determine if debug is enabled or not. Debug is disabled by
default.
