Struct Signature

stack/stack.go:644–690

Signature represents the signature of one or multiple goroutines. It is effectively the stack trace plus the goroutine internal bits, like it's state, if it is thread locked, which call site created this goroutine, etc.

// it's state, if it is thread locked, which call site created this goroutine,
// etc.
type Signature struct {
	// State is the goroutine state at the time of the snapshot.
	//
	// Use git grep 'gopark(|unlock)\(' to find them all plus everything listed
	// in runtime/traceback.go. Valid values includes:
	//     - chan send, chan receive, select
	//     - finalizer wait, mark wait (idle),
	//     - Concurrent GC wait, GC sweep wait, force gc (idle)
	//     - IO wait, panicwait
	//     - semacquire, semarelease
	//     - sleep, timer goroutine (idle)
	//     - trace reader (blocked)
	// Stuck cases:
	//     - chan send (nil chan), chan receive (nil chan), select (no cases)
	// Runnable states:
	//    - idle, runnable, running, syscall, waiting, dead, enqueue, copystack,
	// Scan states:
	//    - scan, scanrunnable, scanrunning, scansyscall, scanwaiting, scandead,
	//      scanenqueue
	//
	// When running under the race detector, the values are 'running' or
	// 'finished'.
	State string
	// CreatedBy is the call stack that created this goroutine, if applicable.
	//
	// Normally, the stack is a single Call.
	//
	// When the race detector is enabled, a full stack snapshot is available.
	CreatedBy Stack
	// SleepMin is the wait time in minutes, if applicable.
	//
	// Not set when running under the race detector.
	SleepMin int
	// SleepMax is the wait time in minutes, if applicable.
	//
	// Not set when running under the race detector.
	SleepMax int
	// Stack is the call stack.
	Stack Stack
	// Locked is set if the goroutine was locked to an OS thread.
	//
	// Not set when running under the race detector.
	Locked bool

	// Disallow initialization with unnamed parameters.
	_ struct{}
