| Doc Text: |
A change to Passenger caused applications using Ruby 1.8 or 1.9 cartridges to report pre-starting errors, and applications would only start after a first request was made. The issue was fixed for Ruby 1.9 cartridges in an earlier release of OpenShift Enterprise; this bug fix updates Passenger to correct the issue for Ruby 1.8 cartridges as well. Pre-starting now functions properly for both Ruby cartridges, and the previous errors no longer occur.

This bug isn't reproduced in ose puddle 2014-02-12.1 Openshift enterprise: 2.1/2014-04-03.2 1. Create ruby-1.8/1.9 app 2.

I figured out what is going on. Passenger is set to prepawn. Our apache module is actually patched so that OpenShift can correctly spawn on an IP other than 127.0.0.1. However, the passenger rubygem is not patched. See /usr/share/rubygems/gems/passenger-3.0.21/helper-scripts/prespawn:
class TCPPrespawnLocation < PrespawnLocation
def request_port
@uri.port
end
def connect
TCPSocket.new('127.0.0.1', request_port)
end
end
It turns out it's trying to respawn by issuing a request to itself. However 127.0.0.1 is hardcoded. In my dev environment there actually was something listening on 127.0.0.1:8080 which is why I didn't see the error.
The good news is that this error is "harmless" (technically it breaks prespawning). We'll need to patch the passenger rubygem to know how to prespawn on something other than 127.0.0.1. I'll have to see how Online works around this (if they do).
