tail -f no longer updates after the log is rotated

[andrewchen5678]

When I am trying this configuration with log4rs 1.3.0 with tail -f logs/test.log on a separate terminal, the tail command stops updating after log rotation, I think I have encountered this before in some other setups and it seem to have something to do with the file descriptor got changed or didn't change, or log rotation is not implemented with truncating logs/test.log in place instead. I wonder what it is causing it or there is a setting to make it work like apache's rotatelog utils.

for other use cases when I pipe the log to apache's rotatelogs like this, rotatelogs -n 5 logs/test.log 1M, tail -f continues to receive logs after rotation.

Not sure which behavior is industry standard. I have worked with python before and I don't remember if python allows you to specify rotatelogs behavior. For the mean time I just workaround by using tail -F instead.
