Functions

func CapturePanic

func CapturePanic(logger Logger, retError *error)

CapturePanic is used to capture panic, it will log the panic and also return the error through pointer. If the panic value is not error then a default error is returned We have to use pointer is because in golang: "recover return nil if was not called directly by a deferred function." And we have to set the returned error otherwise our handler will return nil as error which is incorrect

Types

type Logger

type Logger interface {
	Debug(msg string, tags ...tag.Tag)
	Info(msg string, tags ...tag.Tag)
	Warn(msg string, tags ...tag.Tag)
	Error(msg string, tags ...tag.Tag)
	Fatal(msg string, tags ...tag.Tag)
	WithTags(tags ...tag.Tag) Logger
}

Logger is our abstraction for logging Usage examples:

 import "github.com/uber/cadence/common/log/tag"
 1) logger = logger.WithTags(
         tag.WorkflowNextEventID( 123),
         tag.WorkflowActionWorkflowStarted,
         tag.WorkflowDomainID("test-domain-id"))
    logger.Info("hello world")
 2) logger.Info("hello world",
         tag.WorkflowNextEventID( 123),
         tag.WorkflowActionWorkflowStarted,
         tag.WorkflowDomainID("test-domain-id"))
	   )
 Note: msg should be static, it is not recommended to use fmt.Sprintf() for msg.
       Anything dynamic should be tagged.
