[ANN] CGIExt 0.0.2 released - a re-implementation of cgi.rb in C extension

Makoto Kuwata

11/26/2007 2:00:00 PM

Hi, all.

I have released CGIExt 0.0.2.
http://rubyforge.org/projec...


== About

'CGIExt' is a re-implementation of 'cgi.rb' in C extension.
It makes your web application faster.

Currently, not of all functions are implemented.

Notice: This module is still 'alpha release' and it's specification
may change in the future.


== Install

You need C compiler and Ruby's header file to compile CGIExt.

$ tar xzf cgiext-xxx.tar.gz
$ cd cgiext-xxx/
$ ruby extconf.rb
$ make
$ sudo make install


== Usage

The following is an example.

require 'cgi'
require 'erb'
require 'cgiext' # replaces functions automatically

If you require 'cgiext', the following functions are replaced by
faster implementation of CGIExt.

* CGI.escapeHTML()
* CGI.unescapeHTML()
* CGI.escape()
* CGI.unescape()
* CGI.rfc822_date()
* CGI.parse()
* ERB::Util.h()
* Erubis::XmlHelper.escape_xml()
* Tenjin::HtmlHelper.escape_xml()

Notice that these are replaced only when you have required that
module.
For example, if you have not required ERB before requiring 'cgiext',
ERB::Util.h() is not replaced.


== Benchmark

Try 'bench.rb' included in CGIExt archive.
This script tests functions of CGI and ERB.

### without CGIExt
$ ruby -s bench.rb -N=100000
user system total real
CGI.escapeHTML 5.110000 0.020000 5.130000 ( 5.188709)
ERB::Util.h 5.030000 0.020000 5.050000 ( 5.109625)
CGI.unescapeHTML 31.090000 0.090000 31.180000 ( 31.492502)
CGI.escape 4.630000 0.020000 4.650000 ( 4.679305)
CGI.unescape 3.780000 0.000000 3.780000 ( 3.800455)
CGI.rfc1123_date 2.020000 0.010000 2.030000 ( 2.049406)
CGI.parse 12.030000 0.030000 12.060000 ( 12.156096)
CGI.new 19.670000 0.050000 19.720000 ( 19.854737)

### with CGIExt
$ ruby -s bench.rb -N=100000 -cgiext
user system total real
CGI.escapeHTML 0.990000 0.010000 1.000000 ( 1.026906)
ERB::Util.h 0.960000 0.000000 0.960000 ( 0.971983)
CGI.unescapeHTML 1.200000 0.000000 1.200000 ( 1.210950)
CGI.escape 0.470000 0.000000 0.470000 ( 0.478267)
CGI.unescape 0.340000 0.000000 0.340000 ( 0.343116)
CGI.rfc1123_date 0.600000 0.010000 0.610000 ( 0.634919)
CGI.parse 1.990000 0.000000 1.990000 ( 2.003067)
CGI.new 8.990000 0.020000 9.010000 ( 9.084454)

The result shows that CGIExt makes functions of CGI and ERB
extremingly faster.

Depends on the station. It's on Wisconsin PBS, not Minnesota PBS. I get
both.

I first watched it when Tom Baker(curly hair, long scarf) was the
Doctor, then later earlier and later incarnations, always on Minnesota
PBS back then. I've been dependent on PBS for BBC series for years.

Yeah, like there's another one who wears a scarf?

I haven't seen Doctor Who on PBS in scores.

I was the same way except for me it was KTEH in the SF Bay Area. Of
course now I get my British TV from BBC America.

My late wife knitted me Dr Who scarves, which were a
comfort in a cold London.
