fcgi - The New generation of FastCGI library for Ruby.

Version 0.9.2.1

Depends

C version

Pure Ruby Version

  • StringIO

Install

$ gem install fcgi

Usage

Class Method

--- FCGI.accept Returns FCGI instance --- FCGI.each

--- FCGI.each_request

--- FCGI.is_cgi?

--- FCGI.each_cgi Automatically detects whether this program is running under the FastCGI environment, and generates a 'CGI' type object for each request. Also installs signal handlers for graceful handling of SIGPIPE (which may occur if a client gives up on a request before it is complete) and SIGUSR1 (generated by Apache for a 'graceful' exit)

If you are using the HTML output methods you can also pass the HTML type
e.g. FCGI.each_cgi('html3') do ... end

However, you should beware that the CGI library is quite slow when
used in this way, as it dynamically adds a large number of methods
to itself each time a new instance is created.

Instance Method

--- FCGI#finish Finish

--- FCGI#in Returns Stream or StringIO

--- FCGI#out Returns Stream or StringIO

--- FCGI#err Returns Stream or StringIO

--- FCGI#env Returns Environment(Hash)

Sample

Using the FastCGI native interface:

#!/usr/bin/ruby
require "fcgi"

FCGI.each {|request|
out = request.out
out.print "Content-Type: text/plain\r\n"
out.print "\r\n"
out.print Time.now.to_s
request.finish
}

Using the CGI-compatible interface, which works both as a standalone CGI and under FastCGI with no modifications:

#!/usr/bin/ruby
require "fcgi"

FCGI.each_cgi {|cgi|
name = cgi['name'][0]
puts cgi.header
puts "You are #{name} " if name
puts "Connecting from #{cgi.remote_addr}"
}

Note: you can't reference CGI environment variables using ENV when under FastCGI. It is recommended that you use the CGI-generated methods, e.g. cgi.remote_addr as above.

If you need to access environment variables directly, perhaps extra ones set in your Apache config, then use cgi.env_table instead. This isn't quite as portable because env_table is a private method in the standard CGI library.
