Error reporting when using function mdsvalue in Matlab which version——alpha 7.139-60 about mdsplus HOT 9 CLOSED

Hi, @mwinkel-dev @ModestMC.

• I express my heartfelt gratitude for your generous assistance. I am truly grateful for your help .
• Well, I have to admit that I am not very professional in coding. Many days agos, I tried swapping out the MATLAB folder from MDSplus-7.132-0 with the same one from MDSplus-alpha-7.139-60, and it worked. I'm sorry I was too busy and forgot to reply.
• And alpha 7.139.61, this version of the installation package can currently only be installed through Docker on Windows. I have not yet used Docker on Windows, so it may take some time to master it.

Abstract：MDSplus-alpha-7.139-60 (with matlab folder of MDSplus-7.132-0), MATLAB 2022b.

Hi @pvolande,

You're welcome. Glad to read that you were able to fix the API for MATLAB on your computer.

The issue with the alpha 7.139.61 release is that we've been doing maintenance on the build server, and thus the Windows installer for MDSplus was built but not made available.

We are close to finishing the maintenance work on the build server. In a week or so (maybe sooner), you will be able to retrieve the Windows installer from either the mdsplus.org web site or GitHub.

Hi @pvolande,

You can now find the Windows installer (i.e., the *.exe file) for the alpha-7.139-62 release on the GitHub site. This has the MATLAB fix that was introduced in -61.
alpha-7.139-62

We are continuing the maintenance work on our build server. Soon you will also be able to obtain the Windows installer from the mdsplus.org web site.

This bug is likely related to Issue #2660. However, not marking this as a duplicate because the error messages of this bug are not identical to those for #2660. Nonetheless, if the root cause is the same, then PR #2661 will likely fix this bug too.

I wonder if the different messages are the Windows equivalent. @pvolande you may want to test the gm branch that fixes the bug.

Hi @pvolande,

I was unable to reproduce this error using Windows 10, MATLAB R2023b, and MDSplus alpha 7.139.60+ (commit hash f339f5379).

It is odd that the first error message is as follows:

MDSplus.MdsException:  %TREE-W-NOT_OPEN,  Tree not currently open

That is different than the behavior seen with Issue #2660 on Linux. Thus, you've likely encountered a different issue.

Regardless, please try the new alpha 7.139.61 release. Let us know if that fixes the problem.

Hi @pvolande,

CORRECTION: I was able to reproduce the issue using the thin-client mdsip connection. (Previous testing was done with thick-client and distributed-client.)

>> y = mdsvalue(<some_signal>)
Error using javaToMatlab
Java exception occurred:
MDSplus.MdsException: %TREE-W-NOT_OPEN, Tree not currently open

	at MDSplus.Data.execute(Native Method)

	at MDSplus.Data.executeWithContext(Data.java:181)

	at MDSplus.Data.getShape(Data.java:345)


Error in mdsToMatlab (line 13)
        result = javaToMatlab(mdsthing);

Error in mdsvalue (line 53)
result = mdsToMatlab(result);

Hi @pvolande,

I have confirmed that alpha 7.139.61 fixes this MATLAB issue with "thin-client" on Windows 10. And that also confirms that this is a duplicate of Issue #2660.

Hi @pvolande,

I gather that the MATLAB issue has now been fixed at your site, so am closing this issue.
