RollingFileAppender and how rotation is handled

[Zerrossetto]

Hi,
we're currently using logback 1.3.5 on several applications in our company, and I have a technical question regarding file rolling.

Is there someplace that describes how RollingFileAppender handles log files rolling? On an high-level perspective it should be enough understanding the order in which file is renamed, stream to the old active file is closed and then re-opened.
A pointer wher to read on this topic would be very much welcomed.

Hello @Zerrossetto,

Please see ch.qos.logback.core.rolling.RollingFileAppender#rollover

If compression is needed, it happens asynchronously for time based compression. See ch.qos.logback.core.rolling.TimeBasedRollingPolicy#rollover

For FixedWindowRollingPolicy, compression, if requested, happens synchronously.
