Functions

func Format 

func Format(gs ...*Goroutine) []byte

Format formats Goroutines back into the normal string representation.

func NoLeaks 

func NoLeaks(t ErrorReporter, wait time.Duration) func()

NoLeaks helps test that a test isn't leaving extra goroutines after it finishes.

The normal way to use it is: 

func TestFoo(t *testing.T) {
  defer goroutines.NoLeaks(t, time.Second)()

  ... Normal test code here ...

}

The test will fail if there are goroutines running at the end of the test that weren't running at the beginning. Since testing for goroutines being finished can be racy, the detector can wait the specified duration for the set of goroutines to return to the initial set.

Types

type ErrorReporter 

type ErrorReporter interface {
	Errorf(format string, args ...interface{})
}

ErrorReporter is used by NoLeaks to report errors. testing.T implements this interface and is normally passed.

type Frame 

type Frame struct {
	Call   string
	File   string
	Line   int64
	Offset int64
}

Frame represents a single stack frame.

type Goroutine 

type Goroutine struct {
	ID      int64
	State   string
	Stack   []*Frame
	Creator *Frame
}

func Get 

func Get() ([]*Goroutine, error)

Get gets a set of currently running goroutines and parses them into a structured representation.

func Parse 

func Parse(buf []byte, ignore bool) ([]*Goroutine, error)

Parse parses a stack trace into a structure representation.
