Variables

var ErrorHandlers = []func(error){logError}

ErrorHandlers is a list of functions which will be invoked when an unreturnable error occurs.

var PanicHandlers = []func(interface{}){logPanic}

PanicHandlers is a list of functions which will be invoked when a panic happens.

var ReallyCrash bool

For testing, bypass HandleCrash.

Functions

func GetCaller

func GetCaller() string

GetCaller returns the caller of the function that calls it.

func HandleCrash

func HandleCrash(additionalHandlers ...func(interface{}))

TODO search the public functions HandleCrash simply catches a crash and logs an error. Meant to be called via defer. Additional context-specific handlers can be provided, and will be called in case of panic

func HandleError

func HandleError(err error)

HandlerError is a method to invoke when a non-user facing piece of code cannot return an error and needs to indicate it has been ignored. Invoking this method is preferable to logging the error - the default behavior is to log but the errors may be sent to a remote server for analysis.

func RecoverFromPanic

func RecoverFromPanic(err *error)

RecoverFromPanic replaces the specified error with an error containing the original error, and the call tree when a panic occurs. This enables error handlers to handle errors and panics the same way.
