Hello,
I noticed the following behavior from Cfengine 3.0.5p1 till 3.1.2.
Consider the following code:
#####################################################################
#
# promises.cf
#
#####################################################################
bundle common CfControl {
vars:
any::
"InputFiles" slist => {
"cfengine_stdlib.cf",
};
"BundleSequence" slist => {
"Testing"
};
}
body common control {
any::
inputs => { @(CfControl.InputFiles) };
bundlesequence => { @(CfControl.BundleSequence) };
}
#####################################################################
bundle agent Testing {
vars:
any::
"apt_proxy_file" string =>
"/etc/apt/apt.conf.d/02proxy";
methods:
any::
"any"
usebundle =>
get_template("$(apt_proxy_file)","644"),
comment => "Set a proxy for apt",
classes => if_repaired("repaired_AptProxy");
reports:
repaired_AptProxy:: "Repaired promise AptProxy";
}
bundle agent get_template(file,mode) {
files:
any::
"$(file).staging"
copy_from =>
local_cp("$(Dir.repository)/$(file)"),
perms => mo("400","root"),
comment => "Get the template";
"$(file)"
edit_line => expand_template("$(file).staging"),
perms => mo("$(mode)","root"),
create => "true",
comment => "Expand the template";
}
Running this with cf-agent -K -v throws the following error:
cf3 -> Promised file line "" exists within file /etc/apt/apt.conf.d/02proxy
(promise kept)
This line is repeated infinitely until aborted. Upon abort, these are the last
lines shown from the cf-agent process:
cf3 -> Promised file line "" exists within file /etc/apt/apt.conf.d/02proxy
(promise kept)^Ccf3 -> Promised file line "" exists within file
/etc/apt/apt.conf.d/02proxy (promise kept)
!! Could not lock: 9cf3 Received signal 2 (SIGINT) while doing []
cf3 Logical start time Tue Jan 18 21:09:29 2011
cf3 This sub-task started really at Tue Jan 18 21:09:29 2011
cf3 Trying to remove lock - try
cf3 Outcome of version (not specified) (agent-0): Promises observed to be kept
100%, Promises repaired 0%, Promises not repaired 0%
Do you need any more information?
Cheers,
Robert
