NAME Plack::App::Apache::ActionWrapper - Wrapper for Apache2 Action directive for running PSGI apps on shared hosting with FastCGI VERSION version 0.31.0 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; # Some shared hosting providers don't even provide you # with a pointer to your files BEGIN { $ENV{HOME} = '/home/someuser' unless $ENV{HOME}; } # Enable this if you're unable to get output to STDERR # in your normal log file #use IO::Handle; #close STDERR; #open STDERR, ">>", "$ENV{HOME}/fcgi-error.log"; #STDERR->autoflush(1); # 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.
