Description

this needs triage, it is probably a pure upstream cfengine issue? but i'm not sure :)

rlist.c:80: Programming Error: Rlist value contains type f instead of expected scalar

I think there is a tiny programming error as in the error message from rlist.c
most distros lack proper xen integration and will not install the xen tools on a xen domU.

Hello Florian,

Normally, the xen-tools should be installed automatically if relevant, as seen in this inventory/1.0/fusionAgent.st bit:

  vars:
    SuSE.xen_dom0::
      "xen_tools_package" string => "xen-tools";
    SuSE.xen_domu_pv::
      "xen_tools_package" string => "xen-tools-domU";
(...)
  packages:
    xen::
      "${xen_tools_package}" 
        package_policy => "add",
        package_method => generic,
        classes        => cf2_if_else("xen_installed", "cant_install_xen"),
        comment        => "Installing xen package for extended data";

So, on SLES if a Xen DomU is detected, CFEngine would try to install xen-tools-domU using Zypper. Do you see any reason why this would fail on your host ? No usable package source maybe ?

About the programming error, I'm afraid we'll have to use the debug output of CFEngine ... but first, can you tell me if the cf-agent runs anyway or fails short (would be easier to diagnose if it just stops there) ?

Thanks in advance :)

1. I'll add a link to the SUSEStudio builds I'm testing with
2. Installation failed because missing sources, correct
3. As for the agent being OK - I'm not sure. I can answer that once I've dug in deeper. Right now I don't remember enough of cf*...
This is what I see as running:
rudders1:~ # ps -ef | grep cf
root 12373 12337 0 17:07 pts/0 00:00:00 grep cf
root 22113 1 0 05:01 ? 00:00:03 /var/rudder/cfengine-community/bin/cf-execd
What log would you need to tell more? /var/log/messages-ish?

4. Should I open a cfengine bug for it? I take it this really isn't rudder related?

This is Rudder-related. These are Rudder-specific promises. No need to open a CFEngine bug for this.

We should handle the case where the xen* tools are not available, to avoid trying to run them naively. This would be an easy fix.

The strange message (rlist.c:80: Programming Error: Rlist value contains type f instead of expected scalar)
seems to be gone in 2.11.2-2.

Just got info that the message is in fact still shown.
Also, this apparently causes a pretty long boot delay.

Ok this might be different issues.

  1. the rlist.c error - still occurs and should be reproducible simply by installing agent on sles and start of agent
  2. long timeout if policy server is set, but node is not accepted yet
  3. nagging issues if xenstore-ls / xenstore-read aren't installed

I'd love to see 1) disappear since this is embarrassing if people see the boot messages.

I'm closing that one, since - as far as we know - we don't had new occurence of that problem. So maybe nobody has that config case anymore, or it was corrected upstream.
