The 'Configure, ' Resource', 'Cache' column in the output of '-debug all' are the 'domain' of the log events. ImageMagick has a lot of complicated internal moving parts, and one of them is for caching data structures between parts. Those lines that mention Cache are just the log events corresponding to the Cache domain. Its not really something you should concern yourself with unless you're debugging ImageMagick. -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] Scope of classes in CFE 3.10.2 on CentOS 7
Hi folks,
I have a question concerning scope of classes in CFEngine 3. I run CFE
3.10.2 on CentOS 7.4.
# cf-agent -V
CFEngine Core 3.10.2
# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
I'm logged in as root and located in current working dir /root. I have
the following file
# ll ./samples/scope_of_class.cf
-rwx--. 1 root root 720 10. Jul 16:33 ./samples/scope_of_class.cf
with content
BEGIN--
bundle agent scope_of_class()
{
vars:
any::
"web_servers" slist => {
"ws-1.example.com",
"ws-2.example.com",
"webserver.example.com",
};
methods:
any::
"scope_of_class_b1" usebundle => scope_of_class_b1(
$(scope_of_class.web_servers) );
}
bundle agent scope_of_class_b1( server )
{
classes:
any::
"is_dir"
expression => isdir( "/tmp/scope_of_class/$(server)" ),
scope => "bundle";
reports:
is_dir::
"is_dir is SET";
!is_dir::
"is_dir is UNset";
any::
"server = $(server)";
}
END
From my understanding the scope "bundle" is default for a class
definition inside a bundle of type agent, but I added the scope to be
sure. The definition of class is_dir should depend on directories
existing inside /tmp/scope_of_class. I have two subdirectories
# ls -1 /tmp/scope_of_class/
webserver.example.com
ws-1.example.com
but when I run CFE I do NOT get expected behaviour for the definition of
class is_dir:
# cf-agent -IK --file ./samples/scope_of_class.cf --bundlesequence
scope_of_class
info: Using command line specified bundlesequence
R: is_dir is SET
R: server = ws-1.example.com
R: is_dir is UNset
R: server = ws-2.example.com
R: server = webserver.example.com
When the bundle scope_of_class_b1 is processed for parameter
webserver.example.com I expect is_dir to bet set, but from the report it
seems not to be set.
If I change the slist definition to hold "webserver.example.com" as the
first entry, then the class is_dir is set correctly:
# grep slist ./samples/scope_of_class.cf -A 4
"web_servers" slist => {
"webserver.example.com",
"ws-1.example.com",
"ws-2.example.com",
};
# cf-agent -IK --file ./samples/scope_of_class.cf --bundlesequence
scope_of_class
info: Using command line specified bundlesequence
R: is_dir is SET
R: server = webserver.example.com
R: server = ws-1.example.com
R: is_dir is UNset
R: server = ws-2.example.com
It also works "correct" (or as expected by me) if "ws-2.example.com" is
first entry in the slist definition:
# grep slist ./samples/scope_of_class.cf -A 4
"web_servers" slist => {
"ws-2.example.com",
"ws-1.example.com",
"webserver.example.com",
};
# cf-agent -IK --file ./samples/scope_of_class.cf --bundlesequence
scope_of_class
info: Using command line specified bundlesequence
R: is_dir is UNset
R: server = ws-2.example.com
R: is_dir is SET
R: server = ws-1.example.com
R: server = webserver.example.com
I do not understand why the ordering inside slist influences how the
class is_dir will be defined later by CFE for each processing of
scope_of_class_b1.
Some background information: my aim is to create webserver vhost
configuration files where I have two variants, one with SSL
configuration and one without SSL configuration. Which one to configure
depends if the directory with the SSL certificate exists for a given
vhost or not. I'll replace the report promise type by a file promise
type, which should bring the correct vhost configuration file in place,
assumed that I understand how the scope of the class definition works.
Thanks in advance for any help or explanation of that behaviour.
Regards,
Meikel

IBM has finalized its acquisition of Red Hat (https://www.redhat.com/en/about/press-releases/ibm-closes-landmark-acquisition-red-hat-34-billion-defines-open-hybrid-cloud-future) which will operate as a distinct unit within IBM moving forward. What does this mean for Red Hat?s contributions to the CentOS project? In short, nothing. Red Hat always has and will continue to be a champion for open source and projects like CentOS. IBM is committed to Red Hat?s independence and role in open source software communities so that we can continue this work without interruption or changes. Our mission, governance, and objectives remain the same. We will continue to execute the existing project roadmap. Red Hat associates will continue to contribute to the upstream in the same ways they have been. And, as always, we will continue to help upstream projects be successful and contribute to welcoming new members and maintaining the project. We will do this together, with the community, as we always have. If you have questions or would like to learn more about today?s news, I encourage you to review the list of materials below. Red Hat CTO Chris Wright will host an online Q session in the coming days where you can ask questions you may have about what the acquisition means for Red Hat and our involvement in open source communities.
