<pre>**FAIL** WTF_WorkQueue.Simple
../../Tools/TestWebKitAPI/Tests/WTF/WorkQueue.cpp:57
Value of: initialRefCount
Actual: 2
Expected: 1
This is not a bug: we need the second ref to keep the WorkQueue alive in the lambda function where the main loop runs in another thread, in WorkQueue::platformInitialize:
RefPtr<WorkQueue> protector(this);
m_workQueueThread = createThread(threadName, [protector] {
g_main_context_push_thread_default(protector->m_eventContext.get());
g_main_loop_run(protector->m_eventLoop.get());
g_main_context_pop_thread_default(protector->m_eventContext.get());
});
Since we need to keep the WorkQueue alive in another thread, I think the only option is to change the test, not the implementation. CC Brent since he wrote this test. We could guard the reference count checks with #if !PLATFORM(GTK), or just remove the checks completely.</pre>
