[Config4gnu-developer] testing provider

[Enric J. <en...@nm...>]

Hi Jason,

I am testing 0.29, and I get this error when I invoke an operation:

Use of uninitialized value in hash element at /usr/local/lib/openwbem/perlproviders/CFG_Nagios.pl line 52.
Use of uninitialized value in hash element at /usr/local/lib/openwbem/perlproviders/CFG_Nagios.pl line 55.
Use of uninitialized value in hash element at /usr/local/lib/openwbem/perlproviders/CFG_Nagios.pl line 57.
Use of uninitialized value in hash element at /usr/local/lib/openwbem/perlproviders/CFG_Nagios.pl line 59.


I am not an expert in Perl, but the problem I see in that code is that configfile in  getNagios in initialized with a null argument, as getNagios is called without arguments:


sub getNagios
{
        my $configfile = shift;
        ...
}


...
        my $nagios = main::getNagios();
...


On the other, hand I have seen in version 0.30 that getNagios is sometimes called with one or none arguments (for example lines 315 and 392) which in my opinion this is incosistent.

I don't know how to get the configfile in those calls where there is not argument. How can this be solved?

I would really appreciate your comments.

pd. I plan to test and run your provider for a practicum in a course of network management.

Hi,

it seems the config4gnu project is not really active. If you fail 
achieving what you want to do with it, you might want to look at libconf 
(libconf.net), especially the slides of FOSDEM 2005.

best regards,

Thank you Dams, but what I look is a wbem solution. I looked at your slides and seems that libconf is not wbem oriented..
Best regards,

Enric,

I don't have a direct answer for you since Jason has been doing most of the stuff related to WBEM, but I am fairly sure he'll respond to your question.  Just thought I'd let you know.

getNagios() should always be called with a path to the nagios.cfg config 
file. Cases where you see it without an argument are old code and can be 
considered bugs.

I see the places that this happens are in enumInstances handlers. Since 
no Nagios instance is specified, you'll need to iterate through all 
possible Nagios instances... something like

foreach my $configfile (grep(-f $_, @CONFIG_FILES))
{
    my $nagios = main::getNagios($configfile);

    # enum instances for this Nagios
    # ...
}

That's good... it's been ages since I've sent out a status update or 
posted a news item... perhaps this will motivate me to do that...
