Fixed: Can not use a method of an instance if the instance and the type are defined separately



In [ ]:

    
type Data struct {
    value string
}

func (d Data) Value() string {
    return d.value
}

type WithValue interface {
    Value() string
}



In [ ]:

    
d := Data{"hello"}



In [3]:

    
// Got a link error because of https://github.com/golang/go/issues/22998
d.Value()









    



hello



In [ ]:

    
// This works without any problem.
WithValue(d).Value()









    



hello

Fixed: goroutines should be canceled when the main routine ends



In [ ]:

    
import (
    "fmt"
)

i := 0
go func() {
    defer func() {
        fmt.Println("Canceled")
    }()
    for i = 0;; i++ {}
}()









    



Canceled

Fixed: The entire process terminated when a go routine panics



In [ ]:

    
import (
    "fmt"
    "time"
)

go func() {
    panic("die!")
}()

time.Sleep(100 * time.Millisecond)
fmt.Println("main done")









    



panic: die!

Fixed: interface is not working

If you invoke a method through an interface in lgo, it crashes with runtime error: invalid memory address or nil pointer dereference (bug).



In [ ]:

    
import (
    "fmt"
)

type Hello interface {
    SayHello()
}

type person struct {
    name string
}

func (p *person) SayHello() {
    fmt.Printf("Hello, I'm %s.\n", p.name)
}

p := person{"yunabe"}
fmt.Println("---- 1 ----")
p.SayHello()

var h Hello = &p
fmt.Println("---- 2 ----")
h.SayHello()









    



---- 1 ----
Hello, I'm yunabe.
---- 2 ----
Hello, I'm yunabe.

Fixed: GC crashes with a fatal error

The following crashes with fatal error: found bad pointer in Go heap (incorrect use of unsafe or cgo?) message (bug).



In [ ]:

    
import (
    "fmt"
    "log"
    "runtime"
    "runtime/debug"
)

type MyData struct {
    b []byte
}

func (m *MyData) Size() int {
    return len(m.b)
}

func NewMyData() *MyData {
    return &MyData{
        b: make([]byte, 10 * (1 << 20)),
    }
}

var l []*MyData
for i := 0; i < 100; i++ {
    d := NewMyData()
    l = append(l, d)
}

Fixed: functions and arguments in go statement are not bound immediately

The following code must output goroutine: 0, goroutine: 1 and goroutine: 2 in a random order. But lgo shows goroutine: 3 three times (bug).



In [ ]:

    
import (
    "fmt"
)

for i := 0; i < 3; i++ {
    go func(id int) {
        fmt.Println("goroutine:", id)
    }(i)
}









    



goroutine: 2
goroutine: 1
goroutine: 0
