The current h1_book() macros (and the previous example analyzer code) have an
odd persistency problem: for example, the user wants to change some histogram

Before approving the code, two conditions have to be fulfilled:
1) The code has to work on PSI experiments

We are readying a new release of midas and it is almost here except for a few buglets on the new html status page.

The current ODB code has several structural problems and I think I now figured out how to straighten them out.
Here is the problems:

All makes sense to me. I agree to proceed with the refactoring.
One additional comment: In the 90's when I developed this code, locking was expensive. On a decent computer you could do a couple of thousand lock operations |

Good afternoon,
After updating Midas to the latest develop commit

Could you please export and send me the /Sequencer ODB tree (or just /Sequencer/Param and /Sequencer/Variables) in both cases while the sequence is running.
|
|

|
Ok, here is the complete code to reproduce the problem. Load parameter_test.msl which includes functions.msl. From the screenshot you see the variables
containing
garbage, and you also see that from the ODB screenshot. For completeness, I added Sequencer.json which contains the whole sequencer tree.

It is pretty much the same as Stefan, I attach here the screenshots. Also in my case it works sometimes, and sometimes partially (one or 2 params, like
in
attachment 3).

I have been able to reproduce the problem only once. From what I see, it seems that the Variables ODB tree is not initialized properly from the Param tree.
Below are the messages from the failed run compared to a successful one. As far as I could see, the javascript code does not change anything in the Variables
ODB tree (only monitors it). The actual changes are done by the sequencer program, or am I wrong?

Ahh, that rings a bell:
1) JS opens start dialog box

Thanks for the hint Stefan. I pushed a possible fix but I cannot test it since I cannot reproduce the issue.
