netchan: closing a channel on exported end doesn't propagate to the caller #805
Description
by ghexsel:
I have a loop in the exporter sender side that sends 10 items then closes
the netchan. On the importer side, I have a loop to check if the channel
is closed before trying to receive, but the channel doesn't appear to get
closed. Instead, I see the "2010/05/23 16:39:38 importer header: EOF"
message (in the importer receiver side).
A simple solution would be to change the sender side to consider EOF a
close signal on importer.go#run().
Exporter relevant bits:
for i := 0; i < count; i++ {
if closed(ch) {
fmt.Printf("Can't send, channel is closed\n")
os.Exit(1)
} else {
ch <- value {23 + i, "hello"}
}
}
close(ch)
Importer relevant bits:
for {
if closed(ch) {
fmt.Printf("Can't receive, channel is closed\n")
os.Exit(0)
} else {
v := <-ch
fmt.Printf("%v\n", v)
}
}
