> Is this maybe related to what Stefan said about the run start - so that odbedit needs some time to load the bigger ODB?
At the run start mlogger writes the ODB to the .mid file. This needs conversion (binary ODB -> XML ASCII) which can take time.

[quote="Lukas Gerritzen"]It would be nice to have MIDAS notifications pop up outside of the browser window.[/quote]
There are certainly dozens of people who do "I don't like pop-up windows all the time". So this has to come with a switch in the config page to turn it |

Ok, I implemented desktop notifications. In the MIDAS config page, you can now enable browser notifications for the different types of messages. Not sure
this works perfectly, but a staring point. So please let me know if there is any issue.

 12 May 2023, Stefan Ritt, Info, New environment variable MIDAS_EXPNAME
|
A new environment variable MIDAS_EXPNAME has been introduced. This must be
used for cases where people use MIDAS_DIR, and is then equivalent for the
experiment name and directory usually used in the exptab file. This fixes

|
Maybe you remember the problems we had with a custom page in Japan loading it from TRIUMF. It took almost one minute since each RPC request took
about 1s round-trip. This got fixed by the modb* scheme where the framework actually collects all ODB variables in a custom page and puts them
into ONE rpc request (making the path an actual array of paths). That reduced the requests from 100 to 1 in the above example. Maybe the same

The original design of the midas shared memory (back in the 1990's) was that the ODB shared memory file gets

23 Jun 2023, Stefan Ritt, Bug Report, deferred stop transition
|
Deferred transitions were only implemented with a single instance of a program deferring the
transition. To have several instances, MIDAS probably needs to be extended. Certainly this
was never tested, so it's not a surprise that we get a segmentation fault.

|
Indeed that could well be (and is certainly not intended like that). I checked the code
and found that "execute on start run" and "execute on stop run" are called inside
cm_transition(). That means they are executed on the computer which calls cm_transition().
