Dispatcher failed to catch: undefined method `read' for class `FCGI::Stream' (NameError)

Reported by Nathan Reckart | July 27th, 2009 @ 02:05 PM

I have a Rails site hosted on Bluehost, which recently upgraded to Rails 2.3.3. When they did so, it broke my site, which was frozen to Rails 2.3.2. In my fastcgi.crash.log I found the following.

dispatch.fcgi:24 unhandled dispatch error

The attached patch fixes the issue by moving the _rack_read_without_buffer alias to after the definition of the read method.

- State changed from “new” to “invalid”
This sounds like a Rails related bug. I think we should be patching "fcgi_handler" instead.
