I am updating the TRIUMF IRIS experiment to the latest version of MIDAS. I see following error messages in midas.log:
19:06:16.806 2024/05/16 [mhttpd,ERROR] [odb.cxx:6967:db_get_data_index,ERROR] index (29) exceeds array length (20) for key

This is a common problem I also encountered in the past. You get a low-level ODB access error (could also be a read of a non-existing key) and you
have no idea where this comes from. Could be the alarm system, a mhttpd web page, even some user code in a front-end over which the midas library
has no control.

|
Trying to restore IRIS ODB was a nasty surprise, old save files are in .odb format and odbedit "load xxx.odb"
does an unexpected thing.

For everybody using EPICS: There is now a new system called MSetPoint (Midas Set Point) to control whole beamlines via EPICS.
It's under midas/msetpoint and the documentation is here:

Taht's strange. I always was under the impression that .odb files are loaded relatively to the current location in
the ODB. The behaviour should not be different for different data formats, so I agree to change the .odb loading to
behave like the .xml and .json save/load.

Hi all,
On develop, the issue seems to be still there and is not fixed.
The parameters are currently "never" correctly initialized, only as "empty". Tried several times.

|
I traced the problem to a mjsonrpc_db_ls call where I read /Sequencer/Param... . It seems that this sometimes returns a status 312 (DB_NO_KEY) although
I am sure all keys are there in the ODB.
I am still trying to solve this but I may need some help on the mjsonrpc.cxx code.

Hi Thomas,
I have a fix for the issue and I would be happy with testers if you are willing. Simply "git checkout newfeature_ZS" and give it a go. No need to recompile
anything.

Hi Zaher,
thanks for your help.
I just tried the bug fix, but it still seems not to work properly.

Dear experts,
I am a new user of MIDAS. I try to follow the instruction from

I think this may only be an issue on the development branch.
Can you confirm that that is what you are using?

Hello Nick,
I am using the most updated tag: midas-2022-05-c-1284-g4a77127b.

31 Jul 2024, Lukas Gerritzen, Bug Report, New history plots: Zooming in on logarithmic y axis does not work as expected
|
Using the mouse to click and drag on a logarithmic y axis triggers a zooming behaviour as if the user zoomed in on a linear axis.
How to reproduce:

I fixed that and committed the change to megon02, just reload your browser. I also set ymin and ymax of the Vacuum plot to meaningful
values (not to zero!).

07 Aug 2024, Lukas Gerritzen, Bug Report, File name bug in csv export
|
When I export data from a history plot, I get nonsensical filenames. For example, for data from today, I got "Xenon-Vacuum-20247107-152815-20247107-160032.csv".
The month shouldn't be 71 but rather 08. The problem is that in the code it's generated as
[CODE]("0" + leftDate.getUTCMonth() + 1).slice(-2)[/CODE]
