We use the lazylogger for something similar to this. You can specify the path to a custom script, and it will be run for each midas file that gets written:
https://midas.triumf.ca/MidasWiki/index.php/Lazylogger#Using_a_script
This means that you don't have to wait until the end of the run to start processing.

I think it would be useful to find the minimal example that exhibits this behaviour.

|
For those unfamiliar, odbxx is the interface that looks like a C++ map, but automatically syncs with the ODB - https://midas.triumf.ca/MidasWiki/index.php/Odbxx.
I've added a new feature that is similar to the existing odb::connect() function, but works like the old db_check_record(). The new odb::connect_and_fix_structure() |

Looks like a localisation issue. Your floats are formatted as "6,6584e+01", whereas the JSON decoder expects "6.6584e+01".
Can you run the following few lines please? Then I'll be able to write a test using the same setup as you:

This should be fixed in the latest commit to the midas develop branch. The JSON specification requires a dot for the decimal separator, so we must ignore |

Thanks for the bug report Gennaro!
I've fixed the code so that we'll now find the end-of-run ODB dump even if the user is already at the end of the file when they call get_eor_odb_dump().

We have an experiment that's been running for a long time and has some ODB keys that haven't been touched in ages. Mostly related to features that we don't
use like the elog and lazylogger, or things that don't change often (like the logger data directory).
