What, How & Why?
Update the log level threshold to be atomic (thread-safe) and shared across linked instances, such as for the
PrefixLogger
andThreadSafeLogger
that take abase_logger
base reference. This allows the level threshold to be set by the base logger or any linked instances and the new value will be used by all logger instances in the chain. Before these changes, the level threshold was cached by the linked instances and any updates would not propagate to the other loggers in the chain.Also, the test_logger.hpp file was not used by the code base and was removed to prevent confusion.
Fixes #6009
