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 |

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 |

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

trigger event and one periodic event. While the trigger event sets the cache size correctly in the

I will work today on the odbxx API to make sure there are no memory leaks when you switch form one file to another. I talked to KO so he agreed that yo

02 Oct 2025, Stefan Ritt, Forum, struct size mismatch of alarms
|
Sorry to intervene there, but the FEs are usually compiled against libmidas.a . Therefore you have to compile midas, usually do a "make install" to update
the libmidas.a/so, then recompile the FEs. You probably forgot the "make install".
