Limit size of PrivateData blob #3

Closed dwightkelly closed 8 years ago

dwightkelly commented 8 years ago

There's a limit to how much data Switch PrivateData blob can contain. Not documented; however, it's a String so probably 255 or 1024 bytes. Check file size and truncate or error if larger than this limit.

Dwight, did some testing today and wasn't able to reproduce this. Got to 10,000 characters within a PD key and it seems to handle it fine.

function jobArrived( s : Switch, job : Job )
{
    var blob = '';
    var loops = 0;
    var max_loops = 10000;
    var pd_key = "test";

    do {
       blob += "1";    
       job.setPrivateData(pd_key, blob);       
       loops++;

    } while (job.getPrivateData(pd_key) === blob && loops < max_loops);

    s.log(2, "PD value length " + job.getPrivateData(pd_key).length );
    s.log(2, "done, looped " + loops );
}

OK, I didn't know if there was a limit. Just figured it was a string
