  • .z.pd function throwing error for non unique handles

    Posted by user931206 on June 5, 2024 at 2:43 pm

    can someone help with the following error:

    2024.06.05D00:02:14.371532071 | serverName | wdb | procname_wdb | ERR | runHooks | Failed to run hook(“.eod.namespace1.functionname[tab1;tab2]”;”.z.pd – expected unique vector of int handles”)

    This process is started with ” -s -2 “

    the .z.pd function is defined like:

    .z.pd:{$[.z.K<3.3;

    u#int$();

    u#exec w from .servers.getservers[proctype;sortworkertypes;()!();1b;0b]]

    }

    .z.pd is ->

    u

    int$()

    The above is in one of the colums in a table

    time query

    -------------------------------------------------

    2009.08.05D09:25:53.693765248 "function1[params]"

    2012.08.18D19:47:01.117332288 "function2[params]"

    and I run it as {@[value;xquery;{.log.error[name;”Message”]}]}each table

    All the queries ran like this fail.
    Important to mention that even though the process has ” -s -2″ the are not processes started as slaves.
    However, the rest of the code works fine. It’s just this bit that fails.

    sorry about the formatting. it just doesn’t work

    Hi @user931206

    Is it possible you could send a screenshot of the code rather than pasting it in the editor?

    Apologies as this is a problem on our end, not yours.

    Thanks,

    Megan

      Hey

      it would work in this instance, but there have been situations when I needed to give people the code to create a table for testing and a screenshot of the code wouldn’t help anyone.

    Your function is using peach and setting -s -2, it is expecting handles on .z.pd, which is blank and hence failing.

    Start your process

    q -s 2

    q).z.pd:u#int$()

    q).z.pd

    u#int$()

    q){x+til 2} peach til 2

    0 1

    1 2

    q)\s -2

    q){x+til 2} peach til 2

    '.z.pd - expected unique vector of int handles

    [0] {x+til 10} peach til 10

    ^

    q))
