#241 desai [email protected] fixed Cfg: probes will fail to execute
Description

bcfg2 with Gamin.

When using Cfg with probes, I created a directory repo/Probes/ where I put all my probe files.

Gamin adds the directory repo/Probes to the probes to be executed on the client.

The bcfg2 client will fail with the followjng message:

GetProbes completed successfully
Failed to execute probe: /home/gogo/subversion/svn-mj/trunk/bcfg2-repository/Probes
Traceback (most recent call last):
  File "/usr/sbin/bcfg2", line 95, in run_probe
    script.write(probe.text)
TypeError: argument 1 must be string or read-only character buffer, not None
Failed to Execute probes

Also if another directory under repo/Probes/ gets created, the error will appear since probe.text is None.

#696 desai [email protected] wontfix Chained probes (calling probes from within other probes)
Description

I'd like to be able to call a probe from another probe. The driving factor for this is to reduce code duplication in my probes. An example:

I have a probe that uses dmidecode to determine what hardware manufacturer I'm currently running on. This sets a dynamic group that I use within my configuration (manuf-dell, for example).

I have a second probe that queries my RPM database looking for a specific rpm gpg key and sets a dynamic group if I don't find it (rpm_needs_dell_gpg). The problem is, I only want to set this group if I know I'm running on dell hardware.

I have three options for doing this:

  1. One monolithic probe that combines these two options so I reduce code duplication. This is unappealing because this can get large quick (for one script).
  1. Have my rpm_gpg probe issue the same dmidecode command as my manufacturer probe. This is unappealing because that means I have to update two places if I ever need to change the dmidecode call.
  1. Move the manufacturer specific rpm gpg probes into the manufacturer probe. This is unappealing because that means I have to update two places if I ever need to change the rpm calls or methods I use to probe for gpg keys.
