zeripath 3ad62127df Correctly handle select on multiple channels in Queues (#22146) (#22428) ... Backport #22146 There are a few places in FlushQueueWithContext which make an incorrect assumption about how `select` on multiple channels works. The problem is best expressed by looking at the following example: ```go package main import "fmt" func main() { closedChan := make(chan struct{}) close(closedChan) toClose := make(chan struct{}) count := 0 for { select { case <-closedChan: count++ fmt.Println(count) if count == 2 { close(toClose) } case <-toClose: return } } } ``` This PR double-checks that the contexts are closed outside of checking if there is data in the dataChan. It also rationalises the WorkerPool FlushWithContext because the previous implementation failed to handle pausing correctly. This will probably fix the underlying problem in #22145 Fix #22145 Signed-off-by: Andrew Thornton <art27@cantab.net>		2023-01-13 20:42:42 +00:00
