Package joincontext provides a way to combine two contexts.
|
||
|
|
For example it might be useful for grpc server to cancel all handlers in
|
||
|
|
addition to provided handler context.
|
||
|
|
|
||
|

## Example
|
||
|
|
```go
|
||
|
|
ctx1, cancel1 := context.WithCancel(context.Background())
|
||
|
|
defer cancel1()
|
||
|
|
ctx2 := context.Background()
|
||
|
|
|
||
|
|
ctx, cancel := joincontext.Join(ctx1, ctx2)
|
||
|
|
defer cancel()
|
||
|
|
select {
|
||
|
|
case <-ctx.Done():
|
||
|
|
default:
|
||
|
|
fmt.Println("context alive")
|
||
|
|
}
|
||
|
|
|
||
|
|
cancel1()
|
||
|
|
|
||
|
|
// give some time to propagate
|
||
|
|
time.Sleep(100 * time.Millisecond)
|
||
|
|
|
||
|
|
select {
|
||
|
|
case <-ctx.Done():
|
||
|
|
fmt.Println(ctx.Err())
|
||
|
|
default:
|
||
|
|
}
|
||
|
|
|
||
|
|
// Output: context alive
|
||
|
|
// context canceled
|
||
|
|
```
