Hi,
I'm having an issue with a package promise in cf3, was hoping someone
would have an answer.
Basically what we are trying to do is set up a yum repository with
multiple versions of a given package in such a way that we can have cfengine
pin certain versions for certain types of systems (one version of apache for
our main web servers, a different one for drupal installations or one version
for testing while we have an older one in production that sort of thing).
What we've found, though, is that while yum is capable of installing a
specific package version, the package promise in cfengine 3 completely balks
at it. We've tried two test cases so far with poor results.
This is pretty much the code we are using:
packages:
x86_64::
"testpackage"
package_policy => "add",
package_method => yum,
package_select => "==",
package_architectures => { "x86_64" },
package_version => "2.2.15";
}
In the first test testpackage-2.2.15 does not exist in the repo, but
testpackage-2.2.14-6 does. Since we specified that we wanted 2.2.15 we
expected it to be unable to fulfill the promise and just report back the
error. Instead it went ahead and installed 2.2.14-6, and claimed 100% promises
kept.
In the second test we had the equivalent of having 2.2.15 and 2.2.16
in
the repository. This time around the package we requested does exist, but is
not the newest version. In that instance it still claims that 2.2.15 does not
exist, and installs the newer version.
In the first case we end up with the wrong package, potentially with
no
warning that our configuration is incorrect, in the second we're installing a
newer package on systems that shouldn't get it, which could have disastrous
results depending on the package.
I'm not even entirely sure at this point whether the problem lies with
yum, if it's a cfengine bug, or if we're missing something in the rules. Any
advice, thoughts, help, etc. would be highly appreciated, especially since
this looks like it could be a deal breaker for getting cfengine 3 up in our
environment.
Thanks in advance,
Sam Plum
