Default LSAPI Bug
Seems like the latest Ruby LSAPI is not parsing the QUERY_STRING (incorrectly) and PATH_INFO (missing) environment variables. Can this be a bug?

Here is a test URL that shows the output of the LSAPI example:

http://208.78.98.75/asd/ert/?test=right&sdf=324

Notice how QUERY_STRING is empty and PATH_INFO is missing.

Here is some information about my SliceHost server:

Hope this helps,

Please make sure there is no manually installed ruby-lsapi module interfering with the gem installation. Please make sure to remove
/usr/local/lib/ruby/site_ruby/1.8/i686-linux/lsapi.so if there is one.

Then please remove the ruby-lsapi gem and install again.
The "PATH_INFO" env should always be set, but its value may not be correct. Need to fix that.
Please give a sample output of the test URL from WEBrick or mongrel. I need to make sure it is done right this time.

Thanks.

There never was a manual install of the lsapi gem. This was a fresh, recent install.

# updatedb && locate lsapi.so

/usr/lib/ruby/gems/1.8/gems/ruby-lsapi-2.5/lib/lsapi.so

I created a Rails testbed to get a view that does a similar job to the LSAPI example (with more debugging information) and here's the URL for the results:

http://208.78.98.75:4982/asd/ert/?test=right&sdf=324

Here's the code for the view:
Code:
<h1>ENV</h1>
<p><% ENV.each_pair do |key, value| %><%= key %> is <%= value %><br/><% end %></p>
<h1>CGI</h1>
<p><%= h controller.request.cgi.inspect.to_s rescue "ERROR!" %></p>
<h1>FULL REQUEST</h1>
<p><%= h controller.request.inspect.to_s %></p>
And here's the code for the routes:
Code:
ActionController::Routing::Routes.draw do |map|
  map.connect '*url', :controller => "site", :action => "prcs"
end
Please let me know what else I can do to help.

Sincerely,


AEM

Default Confirmed bug on another server
I have tried to test the same problem on another server and I can confirm the same problem:

http://208.78.98.76/asd/ref?test=123

It is also a Ubuntu Dapper server hosted at SliceHost. Same LS version, configuration, Ruby, etc.

Please let me know if there is anything else I can do to help.

Sincerely,


Adrian Madrid

I think I knew why, ruby-lsapi does Rails environment variable fix up if a rail environment has been detected, otherwise standard CGI environment variable is used.
ruby-lsapi checks "RAILS_ROOT" or "RAILS_ENV" as the signature, which will be set automatically when our rails easy setup is used, however, in your manual setup, you use "IGOR_ENV" and "RAILS_ROOT" is not set, so LSAPI does not perform the ENV fix up.

Thanks so much for the information. Wouldn't it be good to add another flag like LSWS_FIX_URLS = 1 to the LSAPI? For people like me that are trying to use the LSAPI directly using RAILS_ROOT or RAILS_ENV seems weird. Maybe adding a note to the examples on the LSAPI would work too.

Thanks again,


Adrian Madrid

I thought that RAILS_ENV is a standard environment variable being referenced internally by the Rails framework. I might be wrong as I am not a real Rails developer.

I'm sorry but I think I didn't make myself clear. I'm trying to use the LSAPI to run my own framework directly. Basically I'm sidestepping Rails and running a small framework that would be lighter and faster for a specific purpose. That is why I was not using RAILS_ENV. I think other people that might want to use the LSAPI directly, without Rails, might like to know that to get access to PATH_INFO and a full QUERY_STRING they need to add a RAILS_ENV constant, or if at all possible, something like LSWS_FIX_URLS. I hope I make more sense now.

Thanks,


AEM
