AttributeError: 'UInt16' object has no attribute '_AccountForMultiplier'

I'm writing a test that checks set DMX address. When running my script once in a while I'll get this exception.

This is happening when setting the DMX address.

I need to run this test an hour, however, I can't run it longer than 10 minutes without running into this exception.

I've seen #884 but it says that the issue has been closed.

I just changed the name to _AccountForMultiplierUnpack in PidStore.py

What version of OLA are you running @ltd9938 and on what OS? This should have been fixed in most supported OSes I believe.

I see your fix worked, but I'm just wondering if something has slipped through the net somewhere.

0.9.5 on Ubuntu 12.04

[peternewman]

Ah that would explain it. I suspect you already know (and I didn't used to be much better), but that's really old and out of support (both the OS and OLA):
https://wiki.ubuntu.com/LTS

On a more helpful note, I'm not clear exactly what you're trying to do, but you know we have a full suite of RDM tests:

Company is requiring 12.04. Is there a way to update OLA? apt-get says it's up to date.

I know about the suite! It's great! I just had to write a basic script to test a small bug in our controllers.

[peternewman]

I work in a large company, but even they try and avoid using unsupported OSes, I'm amazed they're requiring it now when it's been out of support for 9 months or so now!

Probably build from scratch (or debuild the deb from scratch), then use that, our Travis continuous integration was running against 12.04 until not too long ago, so I think it will probably still build fine on that OS.

Now I'm curious, is it a bug our tests didn't catch? You know you can just run selected tests against a device if you want, you don't have to run the entire suite.

We've gotten a report that the DMX start address on our controllers has been resetting to 1 after a certain amount of sets, so I made a script that randomly and continuously set the address.

[peternewman]

Perhaps try that, interspersed with random RDM responder tests, in case it's the act of sending some other PID that gets it in a funny state, which causes the start address set to go wrong.
