Hi guys,

I am using a CGI hack to make SwfUpload work with Rails 2.2.1.

The hack I use is described here:

http://swfupload.org/forum/generaldiscussion/1202

It works fine locally with Webrick, but on my staging server (running
passenger 2.2.5), it fails because the CGI stdinput is empty...

To be more descriptive, in the code (http://gist.github.com/55772) on
line 14, if I output @session.cgi.stdinput, I get an empty string on
my staging server.

On my local machine, I get the uploaded data with my session cookie at
the end (as expected).

I am confused: why would the standard input be empty?? Where do I go
from there? How could I debug what is going on?

Any suggestion welcome.

Cyrille

I'm not sure. Can you check whether @session.cgi is of class
PhusionPassenger::Railz::CGIFixed?

Hi there,

Yes it is. And @session.cgi.stdinput is of class UNIXSocket.

If I check @session.cgi.stdinput.eof? it says true.

So apparently the socket is closed... Is that expected?
Is it possible that the socket content has already been read? If so,
is there a way I can access the request body?

Cheers

Cyrille

Yes, the socket is closed and its contents has probably already been
read by Rails. If you can access the Rails request object you can
extract the parameters from there.

Hi,

thanks for your reply.

I just wanted to point out how I fixed it, in case it helps someone
else:

in the cookie_store, I only have access to the @session object, so to
keep the hack confined there, I had to use the query string instead,
like so:

        cookie_name = @cookie_options["name"]
        reg = %r{#{cookie_name}=(.+)}
        md = reg.match @session.cgi.env_table["QUERY_STRING"]
        if md
          cookie = md[1]
        else
          reg = %r{#{cookie_name}=(.+)&}
          md = reg.match @session.cgi.env_table["QUERY_STRING"]
          if md
            cookie = md[1]
          end
        end

Ugly, but it works.

Cheers

Cyrille
