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:

18 May 2024, Stefan Ritt, Bug Report, odbedit load into the wrong place
|
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.

Good catch. I added your code to the current develop branch of MIDAS.

31 Jul 2024, Stefan Ritt, Bug Report, New history plots: Zooming in on logarithmic y axis does not work as expected
|
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!).

I don't see any bad side effects at the moment, so I accepted the changes and committed them.

We are considering to remove the analyzer framework mana.cxx from MIDAS. It
currently has some compiler warnings and we wonder if we should fix them which
would take some time or just remove the file. We have now to much more modern

19 Aug 2024, Stefan Ritt, Forum, "Safe" abort of sequencer scripts
|
This request came more than once in the past. One thing I could implement is a "atexit" function similarly to the C funciton atexit().
Then we would have a function in the script which gets called whenever one does "stop immediately". This function can then restore

Ok, no relevant complains so far, so I removed mana and rmana from the CMake build
process, but left the file mana.cxx still in the repository for educational
purposes ;-)

I had two free afternoon and took the opportunity to write a new API for the MSCB
system. I'm not sure if anybody else actually uses MSCB (MIDAS slow control bus),
but anyhow.

> First the general advice: if you reduce the "period" of your equipment, then your function will get called more frequently.
> You can set it to 0 and we'll call it as often as possible. You can set this in the ODB at "/Equipment/Python Data Simulator/Common/Period"

16 Sep 2024, Stefan Ritt, Bug Report, Crash using ODB watch
|
The answer is in the error message: „Object went out of scope“. When your frontent_init() exits, the odb objects are destroyed. When you get a callback,
it‘s linked to the
destroyed object. This is like if you have a local string and pass a reference to that string in the return of the function.
|

16 Sep 2024, Stefan Ritt, Bug Report, Crash using ODB watch
|
Well, the object *went* out of scope. For my code it‘s hard to realize this, so the error reporting is poor. Also the first object should have the same
problem. Just by accident that it does not crash.
|
|
20 Sep 2024, Stefan Ritt, Bug Report, Crash using ODB watch
|
The problem has been fixed in the current version. Here is my analysis:
- the midas::odb object *can* go out of scope in the function, since the odb::watch() function creates a deep copy of the object.

> I like the look of std::format, looks cleaner than string streams
I fully agree. String streams is a pain if you want to do zero-leading hex output mixed with decimal output. Yes it's easier to read if you don't know |
