Can AsyncWorker declared in another thread?

[XadillaX]

For some reason (closed source SDK), I must run some code in another thread because that thread is packaged.

And here's my code:

Action ONSListenerV8::consume(Message message, ConsumeContext context)
{
    Message* m = new Message(message);
    ThreadConsumeWorker* worker = new ThreadConsumeWorker(
            parent->GetListenerFunc(),
            *parent,
            m);

    // Nan::AsyncQueueWorker(new ThreadConsumeWorker(
    //             parent->GetListenerFunc(),
    //             *parent,
    //             new Message(message)));

    return CommitMessage;
}

consume is called in a new thread via the SDK, and this code throwed a segmentfault.

So I'm confused can AsyncWorker run in another thread?

No, Nan::AsyncQueueWorker() is supposed to be called from the main thread.

If you want to wake up the main thread from another thread, you'll have to jury-rig something using uv_async_send(). Note that the uv_async_t handle should be initialized on the main thread first. Good luck.

@bnoordhuis So how can I get the loop? Use uv_default_loop? Or via other function of Node.js?

@XadillaX although it's probably not perfect maybe you can get some ideas from https://github.com/fivdi/epoll/blob/v0.1.16/src/epoll.cc. Search for all occurrences of async_g to see what's going on.

@XadillaX uv_default_loop() yes, from the main thread.

@bnoordhuis Thanks!
