[ANN] CGIAlt 0.0.1 released - an alternative library of 'cgi.rb'

[makoto kuwata]

I have released CGIAlt 0.0.1.
http://rubyforge.org/projects/cgiext/

CGIAlt is an alternative library of 'cgi.rb'.

* Compatible with 'cgi.rb' and CGI class
* Faster than 'cgi.rb'
* Available with CGIExt (which is an implementation of cgi.rb in C
extension)

The following is an example of benchmark.

cgi.rb CGIAlt CGIAlt

any thoughts on why i'm not seeing any speedup with this:


#! /opt/local/bin/ruby
require 'rubygems'
require 'cgi'
require 'fcgi'
require 'cgiext'

start_time = Time::now

memory_session = Hash::new{|h,k| h[k] = {}}

FCGI::each_cgi do |cgi|
this_time = Time::now

# hack to get around ruby session bug
session = memory_session[[cgi.cookies
['_session_id']].compact.flatten.first]
last_time = session['last_time']
session['last_time'] = this_time

content = <<-html
<hr>
<b> START_TIME </b> @ <i>#{ start_time }</i>
<hr>
<b> THIS_TIME </b> @ <i>#{ this_time }</i>
<hr>
<b> LAST_TIME </b> @ <i>#{ last_time }</i>
<hr>
html

cgi.out { content }
end


??

cheers.

Hi ara, thank you for trying CGIAlt and CGIExt.

I have released new version of CGIAlt (0.0.2).
It now supports FastCGI.
Could you try new one?

Hi ara, thank you for trying CGIAlt and CGIExt.

I have released new version of CGIAlt (0.0.2).
It now supports FastCGI.
Could you try new one?

sure.

can you confirm that, for cgi i should do

require 'cgialt'
require 'cgiext'

and, for fcgi

require 'cgialt'
require 'cgialt/fcgi'
require 'cgiext'

and that, in both cases, i do not need to require either cgi.rb or
fcgi.{so,rb} ??

cheers.

this is what i'm testing:

#! /opt/local/bin/ruby
require 'rubygems'
require 'cgialt'
require 'cgialt/fcgi'
require 'cgiext'

start_time = Time::now

memory_session = Hash::new{|h,k| h[k] = {}}

FCGI::each_cgi do |cgi|
this_time = Time::now

# hack to get around ruby session bug
session = memory_session[[cgi.cookies
['_session_id']].compact.flatten.first]
last_time = session['last_time']
session['last_time'] = this_time

content = <<-html
<hr>
<b> START_TIME </b> @ <i>#{ start_time }</i>
<hr>
<b> THIS_TIME </b> @ <i>#{ this_time }</i>
<hr>
<b> LAST_TIME </b> @ <i>#{ last_time }</i>
<hr>
html

cgi.out { content }
end




and i don't really see a huge improvement - but it's a very simply
program that may not take advantage of the performance features. can
you suggest a fcgi that should see a significant speedup?

CGIAlt and CGIExt are not the silver bullet for performance.
If CGI class and it's methods were bottle neck of your application,
CGIAlt and CGIExt would be good solution.
But if not, you can't find improvement of performance.


The following is an example of benchmarks. These benchmark scripts are
included in CGIAlt package and you can try them.

CGIExt replaces CGI.escapeHTML and ERB::Util.h and makes them much
faster.
If you use a lot of '<%=h var %>', CGIExt will improve your
application's performance.
