示例1: assertUnlocked
func assertUnlocked(c *gc.C, waiter gate.Waiter) {
select {
case <-waiter.Unlocked():
default:
c.Fatalf("expected gate to be unlocked")
}
}示例2: getWaiterChannel
func getWaiterChannel(waiter gate.Waiter) <-chan struct{} {
// If a gate is unlocked, don't select on it.
if waiter.IsUnlocked() {
return nil
}
return waiter.Unlocked()
}示例3: assertUnlocked
func assertUnlocked(c *gc.C, waiter gate.Waiter) {
c.Assert(waiter.IsUnlocked(), jc.IsTrue)
select {
case <-waiter.Unlocked():
default:
c.Fatalf("expected gate to be unlocked")
}
}示例4: assertLocked
func assertLocked(c *gc.C, waiter gate.Waiter) {
c.Assert(waiter.IsUnlocked(), jc.IsFalse)
select {
case <-waiter.Unlocked():
c.Fatalf("expected gate to be locked")
default:

}示例5: New
// New starts a logsender worker which reads log message structs from
// a channel and sends them to the JES via the logsink API.

// the count (the source of the log messages -
// BufferedLogWriter - handles the actual dropping
// and counting).
//
// Any logs indicated as dropped here are will
// never end up in the logs DB in the JES
// (although will still be in the local agent log
// file). Message dropping by the
// BufferedLogWriter is last resort protection
// against memory exhaustion and should only
// happen if API connectivity is lost for extended
// periods. The maximum in-memory log buffer is
// quite large (see the InstallBufferedLogWriter
// call in jujuDMain).
