is this a bug somewhere?

Dear all,
Stefan and I have been working on improving the sequencer editor to make it look and feel more like a standard editor. This sequencer v2 has been finally
merged into the develop branch earlier today.

Dear Konstantin,
Thank you for your interest in my problem.

ok, thank you for your information. I cannot reproduce this problem, I use vanilla Ubuntu

and latest midas from git.

|
we had a bit of trouble with open network ports recently and I now think security of MIDAS RPC
ports needs to be tightened.
|
15 Apr 2024, Stefan Ritt, Bug Report, open MIDAS RPC ports
|
One thing coming to my mind is the interface binding. If you have a midas host with two networks
("global" and "local"=192.168.x.x), you can tell to which interface a socket should bind.
By default it binds both interfaces, but we could restrict the socket only to bind to the local

Hello there,
in our setup we use many variables with many different exceptions. Would it be possible to implement something like an
IF or/and IF statement? I believe that this is currently not possible.

The tinyexpr library I use to evaluate expressions does not support boolean operations. I would have to switch to the newer

While I will do it, i'm not sure if this is what you want. If I understand correctly, some process gets triggered and then writes some values to the ODB,
then the sequencer
should continue. Putting a wait there is dangerous. Maybe your process always takes like 10-20 ms, so you put a wait of let's say 100ms, and things are |

Ok, I implemented the float second wait function. Internally it works in ms, so the maximum resolution is 0.001 s.
Best,

Indeed there was a sleep(100ms) in the sequencer in each loop. I reduced it now to 10ms. I need at least 10ms since otherwise
the sequencer would run in an infinite loop during the wait and burn 100% CPU. The smallest time slice on Linux to sleep is
10ms, so that's why I set it to that. Give it a try.

Actually I realized that a 1ms wait still works, so I reduced it to that.

30 Apr 2024, Luigi Vigani, Bug Report, Params not initialized when starting sequencer
|
Good afternoon,
After updating Midas to the latest develop commit
|
03 May 2024, Zaher Salman, Bug Report, Params not initialized when starting sequencer
|
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.
|
03 May 2024, Stefan Ritt, Bug Report, Params not initialized when starting sequencer
|
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.
|
03 May 2024, Luigi Vigani, Bug Report, Params not initialized when starting sequencer
|
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).
|
03 May 2024, Zaher Salman, Bug Report, Params not initialized when starting sequencer
|
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?
|
03 May 2024, Stefan Ritt, Bug Report, Params not initialized when starting sequencer
|
Ahh, that rings a bell:
1) JS opens start dialog box
|
03 May 2024, Zaher Salman, Bug Report, Params not initialized when starting sequencer

Thanks for the hint Stefan. I pushed a possible fix but I cannot test it since I cannot reproduce the issue.
> Ahh, that rings a bell:

03 May 2024, Stefan Ritt, Bug Report, Params not initialized when starting sequencer

Seems to me like the problem happens less frequently, but I still see it (1 out of 5 or so). The fact that /Sequencer/Params/Value is empty tells me that
the GUI
has the problem and not the sequencer side.
|
10 May 2024, Zaher Salman, Bug Report, Params not initialized when starting sequencer
|
I think that I finally managed to fix the problem. The default values of the parameters are now written first in one go, then the sequencer waits for confirmation
that everything is completed before proceeding. Please test and let me know if there are still any issues.
