Puppet

Overview: Passenger version 2.2.15 is the most recently released version at the time of this issue. When configured against the puppet 2.6 development master branch, an Exception is thrown in the request/response cycle.

Expected Behavior: A given puppet release should inter-operate with the most current available version of Passenger.

Actual Behavior: The imminent release of 2.6 does not work with the most current available version of Passenger.

Impact Data: Many member of the puppet community use the passenger module loaded into Apache or nginx. These community members are not able to upgrade passenger to take advantage of other bug fixes and security patches.

Detail:

The rack configuration file (config.ru) used is:

config.ru

$:.unshift(‘/opt/puppetlabs/facter/lib’) $:.unshift(‘/opt/puppetlabs/puppet/lib’) $0 = “puppetmasterd” require ‘puppet’ ARGV << “—rack” require ‘puppet/application/master’ run Puppet::Application[:master].run

The exception resulting from a connecting puppet agent is:

[Tue Jul 06 21:12:02 2010] [error] [client 192.168.100.148] Premature end of script headers: hyel.puppetlabs.lan
