Fibaro json problem (HC2 bug? Cache bug?)

[pos 22]

Hi all

 

I log data to a log object through this function in a VD...

Sometimes when the data logs comes very close in time it could look like logg data actually disappear. This can be seen here:

As you could see the log data row is allocated but the data is never written to the VD...

 

However....

After adding more log data to the log object (In this case I turned the AC power of to my alarm that triggered another log object) I can see that the missing stuff was not actually missing. Now it is magically there. So it seem the HC2 holds the data somewhere in RAM but won't write it out to the log object until the next data comes. Sounds like a bug to me... The missing data that is now there is "15:17:58 User Opening P1 User: Isak" and "15:17:54 P1: Entry Delay"

I think this is a potential kernel bug in HC2

Now Fibaro have looked into this and concluded that this probably is "a big one".

 

And Fibaro now says they are working on it...

After some more research it for looks like some kind of libc cache issue between the LUA program and the kernel. Not a kernel issue.

 

If I re-save so the VD service restarts the missing data flush out and is written correctly.
