I would like to see an API that flushes any appenders that have buffered data. E.g. a method LogManager.Flush(). An application might call such a method at regular intervals, e.g. on a Timer.
A naive implementation with the current log4net would iterate through appenders, looking for those that support flushing, and call the appender's flush method, e.g.:
foreach (IAppender appender in
But (a) I'm not sure this is thread-safe and (b) there are potentially other appenders that may want to be able to flush data (e.g. a TextWriterAppender with ImmediateFlush = false).
The request consists of:
- Add an interface, IFlushableAppender or equivalent, with a single method Flush().
- Implement this interface in all relevant appenders (BufferingAppenderSkeleton, TextWriterAppender, ...)
- Add a thread-safe static Flush() method to LogManager.
