示例1: join
// throws on context depth level overflows and cross-context cycles
void c_WaitableWaitHandle::join() {
AsioSession* session = AsioSession::Get();
assert(!isFinished());
assert(!session->isInContext() || session->getCurrentContext()->isRunning());
if (UNLIKELY(session->hasOnJoinCallback())) {
session->onJoin(this);
}
// enter new asio context and set up guard that will exit once we are done
session->enterContext();
assert(session->isInContext());
assert(!session->getCurrentContext()->isRunning());
try {
// import this wait handle to the newly created context
// throws if cross-context cycle found
enterContext(session->getCurrentContextIdx());
// run queues until we are finished
session->getCurrentContext()->runUntil(this);
} catch (const Object& exception) {
// recover from PHP exceptions; HPHP internal exceptions are deliberately
// ignored as there is no easy way to recover from them
session->exitContext();
throw;
}
session->exitContext();
assert(isFinished());
