Bug #2423: Intermittent dependency cycle
http://projects.reductivelabs.com/issues/2423
Author: Alan Harder
Status: Unreviewed
Priority: Normal
Assigned to:
Category: server
Target version:
Complexity: Unknown
Affected version: 0.24.8
Keywords:
I have a setup which fails with "Found dependency cycle" much of the time
(about half? generally within 2-3 runs it'll occur). Using 0.24.8 on Solaris
10.
I've narrowed the code down to this:
<pre>
class cc { notify { 'cc': } }
define util() {
include cc
exec { "util_$name": command => 'echo hoho', require => Class[cc] }
}
define job() {
include cc
exec { "job_$name": command => "echo foo", require => Class[cc] }
}
class app {
util { 'test': }
exec { 'app': command => 'echo hello', refreshonly => true, subscribe =>
Exec['util_test'] }
}
node 'myhost.foo.com' {
include app
job { 'blah': require => Class[app] }
}
</pre>
I have a common component ("cc") and two defines ("util" and "job") that both
use that common component. Then an application ("app") that uses "util" and
subscribes to an exec it has. Finally, I want to use "app" and "job", but want
"app" to be installed first.. so I make it require Class[app].
Here is the error when it fails:
*err: Could not apply complete catalog: Found dependency cycles in the
following relationships: Notify[cc] => Exec[util_test], Exec[util_test] =>
Exec[app], Exec[util_test] => Notify[cc], Exec[app] => Notify[cc],
Exec[util_test] => Exec[job_blah], Notify[cc] => Exec[job_blah], Exec[app] =>
Exec[job_blah]*
And the full output:

Maybe this is a "will not fix" case if I'm using require improperly somewhere..
but it seems like it should be able to do everything "app" needs, and when
"job" is processed it'll just find that Class[cc] is already done.
