Re: [HTCondor-users] job transform: change requirement condition?

[Collin Mehring <collin.mehring@xxxxxxxxxxxxxx>]

Hi Thomas,

You can include the rest of the original value using capture groups. For example:Âregexps("^25(\d+)",unparse(DiskUsage),"33\1")

Also, it looks like you're overriding the entire Requirements _expression_ in that last example instead of DiskUsage.

Hope this helps,

Collin

Hi all,

unfortunately, I have to bother you again about all the transforms...

I am still trying to get my head around the regexp{s} - in the attached
transform rule I am trying to re/set DiskUsage (as example)
 DiskUsage = 2500000
to something else ~~> 3300000
so I assume that
 EVALMACRO tmp.MyReq = regexps("25",unparse(DiskUsage),"33")
would first take the value of 'DiskUsage' and replace '25' by '33' -
however, if I run the rule on the classad [1] the 'whole value' 2500000
get's replaced as 33.
Is there a way to go just for
 '25'00000 --> '33'00000
?

Cheers and thanks,
 Thomas

> condor_transform_ads -verbose -rules example.rule example.classad
EVALMACRO tmp.MyReq to regexps("25",unparse(DiskUsage),"33")
     tmp.MyReq = 33
SET Requirements to 33
DiskUsage = 2500000
Requirements = 33
ResidentSetSize = 500



[btw]
one thing I noted, that condor_transform_ads -verbose exits without any
message and exit code 0 if the input 'class ads' use something dynamic as
 output = /OUT/PATH/mypayload_$(Cluster)_$(Process).out
i.e., when trying a submission set directly - which in hindsight is
comprehensible but irritated me for a minute ;)

probably, condor_transform_ads could throw an error, if it encounters
something unparsable in the context?
