Types

type Finder

type Finder struct {
	FilePaths [3]string
	Dumps     [3]*obj.Dump

func NewFinder

func NewFinder(filePath1, filePath2, filePath3 string) *Finder

NewFinder returns a new *Finder instance, populated with the three given file paths.

func (*Finder) FindLeaks

func (s *Finder) FindLeaks() []*string

FindLeaks finds potential memory leaks by removing all objects in heap dump #1 from heap dump #2, and then also removing all entries from heap dump #2 which are not present in heap dump #3.

func (*Finder) PrintLeakedAddresses

func (s *Finder) PrintLeakedAddresses()

PrintLeakedAddresses prints the memory addresses in hex (0x...) format for all objects which are likely to be leaked memory.

func (*Finder) PrintLeakedObjects

func (s *Finder) PrintLeakedObjects() error

PrintLeakedObjects prints the full JSON blobs for all objects which are likely to be memory leaks.

func (*Finder) Process

func (s *Finder) Process() error
