Implemented max log file size with truncation.

[akotulu]

Our projects use file logging and atm logs have grown to ~18GB, so implemented file max size with half way truncation.

Found few corner cases, fixed those.

Will this feature be merged to master or I need to do a patch file for it?

I'm not the best for that.

But I think that this job is for the OS, perhaps with the help of the app (not necessarily) .

Well managing log files with aka logrotate isn't possible for all the solutions. Our micro services have each a WS server included and deploy generates each time a unique directory for rollback. So this would become a nightmare to manage. Most of the programs manage log files internally.

OK
But why this internal solution, and not an external lib for that ?

By default the actual, if set another log engine, use it !!
