Functions

func DumpPreviousStacktrace

func DumpPreviousStacktrace()

DumpPreviousStacktrace dumps the previous human readable stacktrace to fd, which is set by SetSignalDumpToFd.

func DumpSignalTo

func DumpSignalTo(fd int)

DumpSignalTo redirects log to fd, -1 if not set; muted if < 0.

func DumpStacktraceTo

func DumpStacktraceTo(name string)

DumpStacktraceTo set dump file path of stacktrace when signal is triggered "*.stacktrace.dump" under a temp dir if not set.

func Notify

func Notify(c chan<- os.Signal, sigs ...os.Signal)

Notify act as signal.Notify, which invokes the Go signal handler. https://godoc.org/os/signal#hdr-Go_programs_that_use_cgo_or_SWIG Notify must be called again when one sig is called on windows system as windows is based on signal(), which will reset sig's handler to SIG_DFL before sig's handler is called While unix-like os will remain sig's handler always.

Example

Output:

Got signal: interrupt

func PreviousStacktrace

func PreviousStacktrace() string

PreviousStacktrace returns a human readable stacktrace

func SetSigInvokeChain

func SetSigInvokeChain(to os.Signal, wait os.Signal, sleepInSeconds int, froms ...os.Signal)

SetSigInvokeChain sets a rule to raise signal to {to} and wait until {wait}, done with sleep {sleepInSeconds}s

func Signum

func Signum(sig os.Signal) int
