 18 Sep 2024, Marius Koeppel, Bug Report, Crash using ODB watch
|
I created a PR to fix this issue https://bitbucket.org/tmidas/midas/pull-requests/42.
The crash happened since the change in commit 3ad98c5 always got the ODB via XML.
However, the creation from XML should only be used when a user wants to read fast (and when we are on a remote machine) so I added the flag use_from_xml |

Hi all,
we have a CI setup which fails since 06.05.2025 to build the history_schema.cxx. There was a major change in this code in the commits fe7f6a6 and 159d8d3.

25 Nov 2020, Marco Francesconi, Suggestion, ODBSET wildcards with array keys in Sequencer files

Hi,
I guess the issue is in the "[?]" part of the command, the indexing is handled differently from the odb path and does not
support "?".

I created some keys in my ODB to try to match yours.
The ODBSET commands you wrote are all working fine (of course with different results), except only for the "/Detectors/Det*/Settings/Charge/Bias (V)*"
which I will have to

I totally agree that we should have a consistent formatting for array index expansion.
I had a look to the mjsonrpc code and I found the function parse_array_index_list(...) which does this job.
I have a similar function (adapted form previous code) in odb.cxx called strarrayindex(...) that is designed for the same "consistency" purposes between |

16 Jun 2021, Marco Francesconi, Info, 1000 Mbytes/sec through midas achieved!
|
As reported by Stefan, in MEG II we have very similar ethernet throughputs.
In total, we have 34 crates each with 32 DRS4 digitiser chips and a single 1 Gbps readout link through a Xilinx Zynq SoC.
The data arrives in push mode without any external intervention, the only throttling being an optional prescaling on the trigger rate.

25 Jun 2021, Marco Francesconi, Bug Fix, changes in history plots
|
We are using the new history formula as a quick way to convert signals from sensors to actual physical values (for example Voltage->Temperature, Voltage->relative
humidity
...), so it is great that the shown voltage is the calculated one.

28 Jun 2021, Marco Francesconi, Suggestion, ODB Load in Sequencer
|
Hi all,
for my experiment we ended up with the need of changing lot of parameters (~9000 values) in the ODB at once by the sequencer.
The very first solution was to use a sequencer function with a ton of ODBSET calls, however a more elegant solution may be to provide an "ODBLoad" command |

My idea was to collect some feedback instead of blindly submitting code for a pull request.
Currently I'm just calling db_load() with a given file, so it is only supporting .odb formatting.

I just submitted a pull request for this feature, I did quite a lot of testing and it looks good to me.
Let me know if something is not clear.

Recently I was trying to read sequencer scripts written by a previous student, and realized it would be easier to
