I have released jsTenjin 0.0.2.
http://www.kuwata-lab.com/tenjin/

jsTenjin is a very fast and lightweight template engine for JavaScript. It is especially designed for server-side programming and works on both SpiderMonkey and Rhino. Also jsTenjin package contains client-side library which is a subset of server-side library.

0.0.2 is a bug fix release.

Bugfix

On SpiderMonkey, if template was large (>=4KB) then Tenjin#readFile() inserted extra commas (’,'). Now fixed.

This bug is reported by P.Khodko. Thank you very much.

Mod_fcgi is Great

Filed under: server on Sunday, December 30th, 2007 by kwa | No Comments

Mod_fcgi is an alternative apache2 module of mod_fastcgi. I have installed mod_fcgi and found it great.

Benefit of mod_fcgi:

Process management is sophisticated.
- No FastCGI process is spawned at first. Prcoess is spawned only when request is comed.
- Number of processes is increased automatically according to the load of server.
As fast as mod_fastcgi.
No need to install FastCGI Development Kit.

It’s time to swtich mod_fastcgi to mod_fcgid!

Tips to Debug Ruby CGI script

In Ruby CGI script, error messages are printed only in log file. If you got any errors, you must look up log file to know what and where error raised. This is not difficult, but a bother thing.

The following script named ‘cgi_exception.rb’ is a tiny script to display exception in browser like PHP. If you require ‘cgi_exception’, it will help you to know what and where exception raised.

Patch for ruby-fcgi

Filed under: ruby on Sunday, December 16th, 2007 by kwa | No Comments

Current Ruby FastCGI module doesn’t allow you to specify port number or unix domain socket file path of connection.

I have create a patch to enable to specify port number or socket file path. If you have applied the patch, the following code is available.

require 'rubygems'
require 'fcgi'
arg = "/tmp/mysocket.sock"   # or arg = 8001   # port number
FCGI.each(arg) do |req|
  req.out.print "Content-Type: text/html\r\n"
  req.out.print "\r\n"
  req.out.print "<html><body>Hello World!</body></html>\n"
  req.finish
end

The following is a patch for ruby-fcgi/ext/fcgi/fcgi.c:
