Hi,
I'm seeing a number of issues with your example code...
You are creating a slice of channels when you really could just use a
single channel to receive all of the results.
You wait on a WaitGroup, but the goroutines only call Done() *after* they
are able to send their result on the channel.
I am implementing a multi part file downloader and I need help to find the
blocking element in the following piece of code.
func downPart(wg *sync.WaitGroup, url string, dataChan chan []byte, range1,
range2 int) {
defer wg.Done()
client := new(http.Client)
req, _ := http.NewRequest("GET",
