I hopefully fixed the waring (narrowing down from size_t to int). Please double check with your compiler.

A new sequencer which understands Python is in the works. There you can use all features from that language.

The extended ODBSET[x,y1-y2,z] could make sense to be implemented, since it then will match the alarm system which uses the same syntax.
The $GOODCHANNELS/$BADCHANNELS is however a very strange syntax which I haven't seen in any other computer language. It would take me probably several |

If people are simultaneously editing scripts this is indeed an issue, which probably never can be resolved by technical means. It need communication between
the users.

30 Apr 2025, Stefan Ritt, Info, New ODB++ API
|
I had to change the ODBXX API: https://bitbucket.org/tmidas/midas/commits/273c4e434795453c0c6bceb46bac9a0d2d27db18
The old C API is case-insensitive, meaning db_find_key("name") returns a key "name" or "Name" or "NAME". We can discuss if this is good or bad, but that's |

05 May 2025, Stefan Ritt, Bug Report, abort and core dump in cm_disconnect_experiment()
|
I would be in favor of not curing the symptoms, but fixing the cause of the problem. I guess you put the watchdog disable into mhist, right? Usually mhist
is called locally, so no mserver should be
involved. If not, I would prefer to propagate the watchdog disable to the mserver side as well, if that's not been done already. Actually I never would |

05 May 2025, Stefan Ritt, Info, db_delete_key(TRUE)

I would handle this actually like symbolic links are handled under linux. If you delete a symbolic link, the link gets
detected and NOT the file the link is pointing to.

 10 Jun 2025, Stefan Ritt, Info, History configuration changed
|
Today the way the history system is configured has changed. Whenever one adds new equipment
variables, the logger has to add that variable to the history system. Previously, this happened during
startup of the logger and at run start. We have now a case in the Mu3e experiment where we have many

We had issues with the frontend write cache size and the way it was implemented in the frontend
framework mfe. Specifically, we had two equipments like in the experiment/examples/frontend.cxx, one
trigger event and one periodic event. While the trigger event sets the cache size correctly in the
