StreamingFast Logging library

This is the logging library used as part of StreamingFast.

Usage

In all library packages (by convention, use the import path):

var zlog *zap.Logger

func init() {
	logging.Register("github.com/path/to/my/package", &zlog)
}

In main packages:

var zlog *zap.Logger

func setupLogger() {
	logging.Register("main", &zlog)

	logging.Set(logging.MustCreateLogger())
	// Optionally set a different logger here and there,
	// using a regexp matching the registered names:
	//logging.Set(zap.NewNop(), "eosdb")
}

In tests (to avoid a race between the init() statements)

func init() {
	if os.Getenv("DEBUG") != "" {
		logging.Override(logging.MustCreateLoggerWithLevel("test", zap.NewAtomicLevelAt(zap.DebugLevel)), ""))
	}
}

You can switch log levels dynamically, by poking the port 1065 like this:

On listening servers (port 1065, hint: logs!)

• curl http://localhost:1065/ -XPUT -d '{"level": "debug"}'
