custom fact not working when running via puppet on RHEL5

[Benjamin DUPUIS]

Hi,

I've this custom fact,
- it's working fine when running via puppet on Debian 6-7, Centos/Rhel 6
- it's going on timeout when running via puppet on Rhel5. "Warning: Could not load fact file /var/lib/puppet/lib/facter/interfaces_duplex.rb: execution expired"
- it's working fine when I get it via "facter -p" on all my Linux

Is anyone have an idea why ? All my nodes are running puppet 3.6.2 (package from puppetlabs)


cat /var/lib/puppet/lib/facter/interfaces_duplex.rb
if Facter.value(:kernel) == 'Linux' and Facter.value(:virtual) =~ /^(physical|vmware|xen0)/
  Dir.glob('/sys/class/net/{eth,em}?').each do |iface|
    fstate = File.open(File.join(iface,'operstate'))
    state = fstate.read
    if state.strip() == 'up'
      Facter.add("duplex_" + File.basename(iface)) do
        confine :kernel => 'Linux'
        setcode do
          fduplex = File.open(File.join(iface,'duplex'))
          if fduplex
            duplex = fduplex.read
            duplex.strip()
          end
        end
      end
      Facter.add("speed_" + File.basename(iface)) do
        confine :kernel => 'Linux'
        setcode do
          fspeed = File.open(File.join(iface,'speed'))
          if fspeed
            speed = fspeed.read
            speed.strip()
          end
        end
      end
    end
  end
end

Best regards,
Benjamin

hi,

Some more debug ...

strace  puppet agent -t

open("./interfaces_duplex.rb", O_RDONLY) = 5

 lsof when running puppet - /sys/class/net/eth0/operstate is open 2 times :

COMMAND  PID USER   FD   TYPE             DEVICE SIZE/OFF     NODE NAME

puppet  9952 root    4r   REG                0,0     4096     5043 /sys/class/net/eth0/operstate
puppet  9952 root    5r   REG                0,0     4096     5043 /sys/class/net/eth0/operstate

lsof when running facter -p - /sys/class/net/eth0/operstate seem to be open only a time
