Hey folks,
I have a problem with the definition of a variable of type slist in
CFEngine on
# uname -a ; cat /etc/redhat-release
Linux policyhub.example.com 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22
21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
CentOS Linux release 7.4.1708 (Core)
I'm not sure if its valid to ask CFEngine questions on this mailing
list, but as far as I'm running on CentOS I hope that it is okay.
I'm logged in as user
# id

Kontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
and working on directory
# pwd
/var/cfengine/inputs
with software
# cf-agent -V
CFEngine Core 3.10.2
and the configuration file
# cat ./info.cf
bundle agent info

I have a problem with the definition of the stringlist/slist
"info_list". In some cases it becomes some kind of "undefined" or at
least I'm not able to print it out in a report (in "r1:"). In the
configuration file above I marked some lines with "BEGIN/END big shit".
Between the BEGIN/END I commented out two lines. If I "run" with that
configuration file I see the reports "r1:" and "r4:" but not "r2:" and
"r3:". It's not clear to me why I don't see reports "r2:" and "r3:", but
I'm interested in the value of $(info.info_list)" in "r1:", I only have
"r2:" and "r3:" here to maybe help to localize the problem which is
described later. Definition of "info_list" works fine for now:

"r2:" and "r3:" are missing, but thats not a problem for me. Now I
comment in one of those two lines, in this case th first one:
# cat ./info.cf
bundle agent info
{

"sys.ip2iface ............... = $(sys.ip2iface)",
"sys.ipv4 ................... = $(sys.ipv4)",
"sys.key_digest ............. = $(sys.key_digest)",

"sys.release ................ = $(sys.release)",
"sys.resolv ................. = $(sys.resolv)",
"sys.statedir ............... = $(sys.statedir)",
"sys.sysday ................. = $(sys.sysday)",
"sys.systime ................ = $(sys.systime)",
"sys.update_policy_path ..... = $(sys.update_policy_path)",

};
reports:
any::
"r1: $(info.info_list)";
"r2: sys.inet6 .................. = $(sys.inet6)";
"r3: sys.interfaces_data ........ = $(sys.interfaces_data)";
"r4: holleri di dudeldoe";
}
I "run" again with that configuration file and in report "r1:" I can see
that now the stringlist/slist "info_list" seems to be undefined and
report "r1:" is empty and reports "r2:" and "r3:" are still missing:
# cf-agent -IK --file ./info.cf --bundlesequence info
info: Using command line specified bundlesequence
R: r1: $(info.info_list)
R: r4: holleri di dudeldoe
My problem ist NOT that the reports "r2:" and "r3:" are not printed, my
problem ist, that in some cases the slist is undefined. I'm using that
slist to collect some system info and then printing out the report and
it would NOT be a problem if some system informations were missing but
it IS a problem that in some cases the whole slist becomes undefined and
in that situation I receive a completly empty report "r1: ".
I would like to understand what circumstances lead to the slist be
undefined and how I can prevent this.
Thanks in advance.
