Exception IOError in Passenger RequestHandler (closed stream)

[P.A.]

Hi.

I've just started to use Phusion Passenger and I wrote a simple Rack
application. When I start it I get the error:

*** Exception IOError in Passenger RequestHandler (closed stream)

2009/11/14 17:50:33 [error] 3086#0: *12 upstream prematurely closed
connection while reading response header from upstream, client:

upstream: "passenger://unix:/tmp/passenger.3069/master/
helper_server.sock:", host: "localhost:1234"

Here it is the application itself:

# test/controllers/controller.rb
# encoding: utf-8
class Test
def call(env)
body = Rack::Request.new.params
# If I set body to an arbitrary string or to any other methods
# of the instance of Rack::Request, say get?, post?, env
# all works.
[200, {}, body.inspect]
end
end

# test/config.ru
require 'controllers/controller'
run Test.new

Here it is my environment:

Debian GNU/Linux 5.0.2;
Ruby 1.9.1;
Rack 1.0.0;
Phusion Passenger 2.2.5;
nginx 0.8.24.

Here it is the nginx configuration:

# <nginx_install_dir>/conf/nginx.conf

worker_processes 1;

events {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
passenger_root /home/<user_name>/.gem/gems/passenger-2.2.5;

server {
listen 1234;
server_name localhost;
root /home/<user_name>/development/nginx/test;
passenger_enabled on;
}
}

What is the reason of this bug? How can I fix it?

Thanks.

This is a bug in Ruby 1.9's tempfile library. It's been fixed in Ruby
SVN but there hasn't yet been a new release with the bug fix.

I installed Ruby 1.9.2dev from SVN. The bug disappeared. Thanks for
help.

Unfortunately, 1.9.2 Preview 1 still has this bug — wonder why the fix
wasn't merged.

I just commented out line 140 of tempfile.rb and it plays nice with
Passenger again.

if File.exist?(@tmpname)
# closed? or close <------ comment out
File.unlink(@tmpname)
end
