INFO messages about performingChange method

[DiamondJim87]

Not sure when this started, but in my console as our tools run the following kinds of messages frequently are printed now.

INFO: no lock object found for tcaload_axis_29
Jul 25, 2023 9:51:59 AM org.das2.system.ChangesSupport changePerformed
INFO: expect value for changeCount tcaload_axis_29, was performingChange called?

I'm not aware of a code change on our end that caused this. Any idea what these mean or what I could change so as not to trigger them?

[jbfaden]

I can't think of any changes made in the past 5 years with the tca loading. I take it everything is working properly. I think we should just lower the message from INFO to FINE if things are working.

Honestly I'd have to study it all to remind myself what the concern was.

[DiamondJim87]

After I filed this, I did look in other issues, and #32 seemed possibly related. That was about a year ago. Is it possible that change is interacting with the TCA code?

[jbfaden]

Yes, I agree that's probably related, I'd forgotten about (blocked out painful experience) that ticket. I take it you can't easily share code which demos the problem, right? Can you see that the right ephemeris is loaded? The gist of it is that locking needs to be done so if you say "load the data and make a png" it knows when the data has been loaded. There's something wrong with the mechanism which detects if all the loading is done.

[jbfaden]

Whoops, I didn't mean to close this.

[jbfaden]

Does this continue to be an issue?

[DiamondJim87]

Yes I just confirmed it still happens. As the message suggests, it only happens when I have TCA functions.
