Types ¶

type Dump ¶

type Dump struct {
	FilePath string
	Index    []*string
	Entries  map[string]*Entry
}

Dump contains all relevant data for a single heap dump.

func NewDump ¶

func NewDump(filePath string) *Dump

NewDump returns a *Dump instance populated with the specified file path.

func (*Dump) PrintEntryAddress ¶

func (s *Dump) PrintEntryAddress(indexes []*string)

PrintEntryAddress prints the memory addresses in hex (0x...) format of the entries for the list of given indexes.

func (*Dump) PrintEntryJSON ¶

func (s *Dump) PrintEntryJSON(indexes []*string) error

PrintEntryJSON prints the full JSON blob from the input file for the entries with the given indexes. It does this by using the Offset value of the entries to avoid having to load up the whole dump file in memory.

func (*Dump) Process ¶

func (s *Dump) Process() error

Process processes the heap dump

type Entry ¶

type Entry struct {
	Object *Object
	Offset int64
	Index  string
}

Entry is a parsed heap item object

func NewEntry ¶

func NewEntry(inputJSON []byte) (*Entry, error)

NewEntry returns a new *Entry instance initialized with a *Object of the given input JSON data.

func (*Entry) Address ¶

func (s *Entry) Address() string

Address returns the Address property of the entry's Object.

type Object ¶

type Object struct {
	Address string `json:"address"`
	Type    string `json:"type"`
}

Object is a minimal representation of a Ruby heap object as exported from Ruby via `ObjectSpace.dump_all`.

func NewObject ¶

func NewObject(inputJSON []byte) (*Object, error)

NewObject returns a new *Object instance with it's attributes populated from the given input JSON data.

func (*Object) Index ¶

func (s *Object) Index() string

Index returns a unique index for the given Object.

func (Object) MarshalEasyJSON ¶

func (v Object) MarshalEasyJSON(w *jwriter.Writer)

MarshalEasyJSON supports easyjson.Marshaler interface

func (Object) MarshalJSON ¶

func (v Object) MarshalJSON() ([]byte, error)

MarshalJSON supports json.Marshaler interface

func (*Object) UnmarshalEasyJSON ¶

func (v *Object) UnmarshalEasyJSON(l *jlexer.Lexer)

UnmarshalEasyJSON supports easyjson.Unmarshaler interface

func (*Object) UnmarshalJSON ¶

func (v *Object) UnmarshalJSON(data []byte) error

UnmarshalJSON supports json.Unmarshaler interface
