Ruby Setup - LSAPI
 
Okay, so I'm setting up Ruby (not Ruby on Rails) to work with LSWS with the new LSAPI module, and I need a little help. I decided to use the dispatcher, so I created a LSAPI module with a url of a /tmp/lshttpd/ruby_ns.sock, and the command being the lsruby_runner.rb script. I added a Script Handler for .rb, and it's returning a 503...I know I'm doing something wrong, which is why I'm asking for a little help here. :)

Have you built and installed the ruby extension? Is execution bit enabled for ruby_runner.rb?
For trouble shooting, please check lsws/logs/error.log and stderr.log

Xorlev 04-27-2006 10:01 PM
Yes, I built and installed the Ruby extension, and it is chmodded to allow execution.

Don't know what exactly is the problem, below is our RubyRunner configuration, you can give it a try.


Code:
Name RubyRunner
Address uds://tmp/lshttpd/rubyrunner.sock
Max Connections 10
Environment N/A
Initial Request Timeout (secs) 60
Retry Timeout (secs) 0
Persistent Connection Yes
Connection Keepalive Timeout N/A
Response Bufferring No
Auto Start Yes
Command $SERVER_ROOT/fcgi-bin/lsruby_runner.rb
Back Log 10

Okay, it's halfway working now (no more errors in log), but now it returns a 500 error.

I am not exactly sure what is the problem, maybe support for your ruby script is poor. You can try the following hello.rb, if it works, please send us your testing script, we will figure out the problem.

Code:
#!/usr/local/bin/ruby

print "HTTP/1.0 200 OK\r\nContent-type: text/html\r\n\r\nHello World!\r\n"
ENV.each_pair {|key, value| print "#{key} is #{value}
\r\n" }

Xorlev 05-02-2006 08:24 PM
Aha it works now with the script you gave me, however it appears your testcgi.rb script is malfunctioning on my setup, which was what "test.rb" was.

mistwang 05-03-2006 07:46 AM
testcgi.rb itself is using LSAPI interface, it is for testing the ruby "cgi" extension under LSAPI. Itself is a LSAPI application, It will not work under the lsruby_runner.

Xorlev 05-03-2006 12:37 PM
Aha, I should have thought of that. :oops:

Thank you for your help, and out of curiousity how would I make LSAPI work directly from the script (ie, requiring it in then using the blocks given)? A context?

mistwang 05-03-2006 02:06 PM
Yes, the extra code for LSAPI is pretty simple.
You need to define a LSAPI application for each LSAPI ruby script, then mount the application via a context or script handler.
