|
> 1) history is independent from "runs", we see a change, we apply it (even if it takes 10 sec or 2 minutes).
>
> 2) "nothing should change during a run", we must process all changes before we start a run (starting a run takes forever),

> Now, mlogger just silently continues not writing to history. There is no ongoing error message, there is no

Thanks for reporting this. It was caused by a

> BTW, it looks like we are parsing the whole JSON ODB dump (200k+) on every odbxx access. Can you parse it just once?
You are right. I changed the code so that the dump is only parsed once. Please give it a try.

The Makefile contained the outdated target [B]fal[/B], which is a combined frontend/analyzer/logger. You don't need that, so I removed it from the makefile. |
