Warning; completely untested, but it hopefully indicates the way I was thinking. Mark, does this mean that boolean operations would be a good idea in cfengine?
I don't know what you mean by a boolean operation.
Well, at least a few additional "operators" like "less than" or "greater than" which return true/false to set a class to prevent this kind of senseless abuse of fork() :)
control:
x = ( ExecResult( something-big ) )
y = ( ExecResult( something-small ) )classes:
XisBiggerThanY = ( GreaterThan( $(x) $(y) ) )Yeah, this looks perl-esque, but I think a few extra operators would be handy (We already have a substr() ).. I see there are already tests like this in the cmp= operator for packages: and bymatches= for processes: so it might make sense to refactor that code into something for more general use?
Of course, I could be totally wrong and possibly drain bamaged. YMMV.
--- BEGIN PIE IN THE SKY WISHES --- Even better would be a hook to directories that allows one to generate an action or set a class based on both high a low watermarks:
directories:
SomeHost::
/path/to/dir
maxfiles=1000
minfiles=2
define=DespoolSomeAppQueueHitting maxfiles would define the classes in define=, hitting minfiles
would act similarly to the way SensibleCount does currently. Maybe this would be better suited as its own action "filecount:"
Maybe for cfengine-3...

Thanks!
