I seems to find memory leak in Fixed Delay strategy but it may be in others.
if use shorted delay that repeats fun execution time then publisher routine will have locked on sending to signals channel.
maybe should use select for send.
select {
case <-ctx.Done():
return
case ch <- struct{}{}:
sleep(ctx, s.Delay)
}
instead

func TestRepeaterMemoryLeak(t *testing.T) {
unit := func(amout int) time.Duration {
return time.Duration(amout) * 10 * time.Millisecond
}
leak := func() error {
ctx, cancel := context.WithTimeout(context.Background(), unit(3))
defer cancel()
err := NewDefault(3, unit(1)).Do(ctx, func() error {
time.Sleep(unit(2))
select {
case <-ctx.Done():
return nil
default:
return fmt.Errorf("some err")
}
})
return err
}
