Right. No easy subject. For me, too, this has been a problem in MIDAS for a long time.

Hi, Alexandr, thank you for making improvements to MIDAS. I have some question
about your suggestions:

Yes, I think this will work.
For old mfe.c frontends, global variable set to "do it the new way" should be okey,

 30 Nov 2020, Konstantin Olchanski, Info, more wisdom from linux kernel people
|
As you may know, I am a big fan of two software projects - the linux kernel and ROOT. The linux kernel is one of
the few software projects "done right". ROOT is where normal people try to "get it right" with real-world level
of success. I use both softwares daily and I try to apply their ways and methods to MIDAS as much as I can.

I think you are facing several problems:
a) mlogger does not clearly explain what history names will be used for which entries

I am confused by your question. I assume you read a CAEN V792 ADC, but I do not know what VME master you

this is correct, the fevme frontend is written to do 100% CPU-busy polling.

12 Feb 2021, Konstantin Olchanski, Bug Report, mlogger history snafu
|
there is a problem with mlogger between commits xxx (17 Nov 2020) and a762bb8 (12 feb 2021). because of
confusion between seconds and milliseconds, FILE (mhf*.dat files) and SQL history are recording with
incorrect timestamps.
