Go Logging

This project is the crux of our stats pipeline. It contains structures to write and rotate logs files in a fast non-blocking manner. The top levelt interface here is the Logger interface. The main implementer of this interface is the FileLogS3Writer.

The FileLogS3Writer is a Logger that is thread safe. The writer will continue to write to a log until a rotate condition is met. The Writer is implemented with a writer stack. Once a file is rotated the FileLogS2Writer maintains an uploader that will upload the file to S3 with a certain name structure.

The Writer Stack maintains two io.WriterClosers. The first is the current WriterCloser. This is the writer that the stack activly writes to. The second if the next WriterCloser. This is the writer that the stack will switch to using immediatly after recieving a rotate. This architecture allows the WriterStack to continue to log messages in a (nearly) nonblocking manner even through rotations.
