Functions

func DumpStacks

func DumpStacks(dir string) (string, error)

DumpStacks appends the runtime stack into file in dir and returns full path to that file.

func Trap

func Trap(cleanup func())

Trap sets up a simplified signal "trap", appropriate for common behavior expected from a vanilla unix command-line tool in general

• If SIGINT or SIGTERM are received, `cleanup` is called, then the process is terminated.
• If SIGINT or SIGTERM are received 3 times before cleanup is complete, then cleanup is skipped and the process is terminated immediately (allows force quit of stuck daemon)
• A SIGQUIT always causes an exit without cleanup, with a goroutine dump preceding exit.
• Ignore SIGPIPE events.
