Re: [HTCondor-users] Even more job transform questions

[John M Knoeller <johnkn@xxxxxxxxxxx>]

Unfortunately you cannot use complex conditionals in if statements,  you have to force them to evaluate to a boolean first

so you can do this

EVALMACRO QUEUE_CONDITION (JobCategory == "medium") || (JobCategory == "long")
if $(QUEUE_CONDITION)

Also to protect against the JobCategory attribute not being a string, you should use ?:  to force the result to be boolean

EVALMACRO QUEUE_CONDITION (JobCategory == "medium") || (JobCategory == "long") ?: false

It is better to use $INT() rather than $EVAL() because coerces the result to an integer, which behaves like a boolean, while $EVAL does not.

My rule (it’s under construction, hence all the duplication - I’m trying to figure out what is going on):

if !$(IsClusterAd)

    EVALMACRO CLCoreEquiv max({ MY.RequestCpus, int(1 + MY.RequestMemory / 4097) })

    EVALSET CLUserStr   join(":", Owner, $(CLCoreEquiv))

    QUEUE_CONDITION = (JobCategory == "medium") || (JobCategory == "long")

    if $(QUEUE_CONDITION)

        [ … ]

Whereupon the “nice” debugging tool says:

Invalid rules file clim.rule : $(QUEUE_CONDITION) is not a valid if condition because complex conditionals are not supported

When I change that the “if $EVAL(QUEUE_CONDITION)”,

Invalid rules file clim.rule : $EVAL(QUEUE_CONDITION) is not a valid if condition because _expression_ is not a conditional

Help appreciated.
