If I have a select on two channels:
for {
select {
case <-chan1:
// do something
case <-chan2:
// do something else
}
}
And in a separate goroutine I write sequentially to those channels:
chan1 <- "blah"
chan2 <- true
Am I guaranteed to see "do something" execute before "do something else"?
I know that select chooses randomly if it has two unblocked channels, but I was thinking that writing to the first channel might reliably "interrupt" the writing goroutine if the select is already blocking, implying that the select would run on the unblocked first channel before the second write.
