 16 Oct 2014, Stefan Ritt, Bug Report, Problem with EQ_USER
|
I restructured the front-end code to enable multiple readout threads for EQ_USER equipment. Last summer I was definitively interrupted during
that work and left it in an half finished state, sorry for that.

We use binary midas files now for ~20 years and never felt the necessity to put any checksums or even encryption on these files. The reason for that is |

I tested the new scheme and am quite happy with. Just a minor thing. When I change the ACL, I get messages from all attached programs, like:

 10 Dec 2015, Stefan Ritt, Info, Small change in loading .odb files
|
A small change in loading .odb files has been implemented. When you load an array from a .odb file, the indices in each line were not evaluated, only the
complete array was loaded. In our experiment we need however to load only a few values, like some HV values for some channels but leaving the other values
as they are. I changed slightly the code of db_paste() to correctly evaluate the index in each line of the .odb file. This way one can write for example |
