This is the logging library used as part of StreamingFast.
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"}'
