Add pre & post rotate actions. #45

Open ecw19 opened 7 years ago

ecw19 commented 7 years ago

Sometimes we need to perform certain actions before or after logger rotation. It would be very useful if we can have these functions in.

Do you have an example of what you'd like to do before or after a rotation? I'm a little wary of letting people define arbitrary functions for these actions, because this happens inside the time of a log writing, so if you do something that takes a long time, the time to log a single line could be very long.

I work with @ecw19 on the same project. I am not sure why we added PreRotateAction, as we don't appear to be using it. Perhaps just for completeness?

We use the PostRotateAction to upload logs to our analytics service.
