Hi folks and Paul.
Is there any chance that some elements of your info_list become larger than 4K size limit cfengine places on scalar variables?
Mayne the 4K limit ist not the problem here. I did some "shortcutting" and added one more "undefined" variable aaa.bbb.ccc:
# cat ./info.cf bundle agent info { vars: any:: "info_list" slist => { "aaa.bbb.ccc ................ = $(aaa.bbb.ccc)", "includes.dir ............... = $(includes.dir)", "sys.arch ................... = $(sys.arch)", "sys.bindir ................. = $(sys.bindir)", "... BEGIN big shit ...............", # "sys.inet6 .................. = $(sys.inet6)", # "sys.interfaces_data ........ = $(sys.interfaces_data)", "... END big shit ..............." };
reports: any:: "r1: $(info.info_list)"; "r2: sys.inet6 .................. = $(sys.inet6)"; "r3: sys.interfaces_data ........ = $(sys.interfaces_data)"; "r4: holleri di dudeldoe"; "r5: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)";
}
Variables aaa.bbb.ccc and includes.dir are not defined and do not cause any problems:
# cf-agent -IK --file ./info.cf --bundlesequence info info: Using command line specified bundlesequence R: r1: aaa.bbb.ccc ................ = $(aaa.bbb.ccc) R: r1: includes.dir ............... = $(includes.dir) R: r1: sys.arch ................... = x86_64 R: r1: sys.bindir ................. = /var/cfengine/bin R: r1: ... BEGIN big shit ............... R: r1: ... END big shit ............... R: r4: holleri di dudeldoe R: r5: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)
Adding sys.inet6 leads to the problem:
# cat ./info.cf bundle agent info { vars: any:: "info_list" slist => { "aaa.bbb.ccc ................ = $(aaa.bbb.ccc)", "includes.dir ............... = $(includes.dir)", "sys.arch ................... = $(sys.arch)", "sys.bindir ................. = $(sys.bindir)", "... BEGIN big shit ...............", "sys.inet6 .................. = $(sys.inet6)", # "sys.interfaces_data ........ = $(sys.interfaces_data)", "... END big shit ..............." };
reports: any:: "r1: $(info.info_list)"; "r2: sys.inet6 .................. = $(sys.inet6)"; "r3: sys.interfaces_data ........ = $(sys.interfaces_data)"; "r4: holleri di dudeldoe"; "r5: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)";
}
]# cf-agent -IK --file ./info.cf --bundlesequence info info: Using command line specified bundlesequence R: r1: $(info.info_list) R: r4: holleri di dudeldoe R: r5: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)
Why is "r5:" shown but not "r2:" and "r3:"? Why isn't it possible to get the reports "r2:" and "r3:"? There is something special with variables sys.inet6 and sys.interfaces_data in my opinion.

Hey folks,
I have a problem with the definition of a variable of type slist in CFEngine on

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.

The service cfengine3.service is inactive at the moment:
# systemctl is-active cfengine3.service inactive
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:").
Two related questions:
Is there any chance that some elements of your info_list become larger than 4K size limit cfengine places on scalar variables?
Similarly, I wonder if the 4K size limit comes into play when a list is interpolated into a string, as in your r1 report. I'm merely speculating; I don't know one way or the other.
Plus, I've never tried defining a slist with a comma after the final element. I assume that works for you, but I'll just note it for the record.
