9760 :: What is a RollingFileLogger

  Hello world. According to the docs, a RollingFileLogger (in std/logging), is "A logger that writes log messages to a file while performing log rotation". what does it mean ?

  From what I understand of log rotation it's just that the logger will periodically check the log file size and will make sure that the log file does not exceed a certain file limit by pruning the log file if it gets too big

  There is the logrotate tool on many *nix systems and i think the RollingFIleLogger is supposed to mimick some of it's functionality. What it does is explained in detail in man logrotate. The purpose is, as Cnerd says, to periodically check the current log file and rotate to a new one if certain criteria are met (i.e. file size, age). If you would not rotate the log it would grow infinitely.
