QUESTION

Websocket won't reconnect unless I close the browser tab and restart it

Asked 2022-Feb-08 at 15:05

I have a webserver with websockets set up on an ESP8266. The application runs fine on both client and server sides, sending and receiving data. However, if the server side disconnects (power cycle or upload new code), the client (Chrome) won't reconnect to the websocket. I can reload/refresh the web page, and it claims (according to the console log) to be connecting to the websocket, but it does not. The only solution I have found that works is to close the tab, and then restart a new session.

My code is heavily based on this tutorial from Random Nerd Tutorials

websocket::stream_base::decorator(... calls the constructor of decorator. This constructor apparently takes a callable as parameter. The lamdba that is passed has no return. Its return type is void.

See here (link by Some programmer dudes comment): https://www.boost.org/doc/libs/1_78_0/libs/beast/doc/html/beast/ref/boost__beast__websocket__stream_base__decorator/decorator/overload2.html.

QUESTION

How to co_await for a change in a variable using boost coroutine ts?

Asked 2022-Jan-04 at 13:55

Context
I build a webserver using boost coroutine ts, boost asio and boost beast. There is a coroutine for reading and one for writing. There is a message_to_send queue where messages get pushed to send to the user. The writing coroutine checks if there is something in the message_to_send queue and sends it. After sending the writing coroutine suspends itself for 100 milliseconds and checks again for something to write.

Problem
The writing coroutine is polling the message queue every 100 milliseconds. I like to find a solution without polling after some timer has fired.

Posible solution
Maybe ther is a solution to co_await the change of a variable. Maybe creating a async_wait_for_callback with "async_initiate"?

Code example
You can clone the project. Or use the complete example code posted here:

The classical threading solution would be a condition variable. Of course, that's not what you want - I see you even explicitly disabled ASIO threading. Good.

One way - short of providing an Asio service to implement this behaviour - would be to use timers to emulate condition variables. You could use timer that "never" expires (deadline is at timepoint::max()) and manually reset it to timepoint::min() (canceling any async_wait) or any time in the past to signify the condition. Then you can use Timer::async_wait with use_awaitable like you already know how.

Note that you still need to "manually" signal the change. This is what you want because anything else requires kernel process tracing support/hardware debugger facilities which require massive priviliges and tend to be very slow.

You might want to know about associating the use_awaitable as the default completion token for the executor bound to your timer. See e.g. the examples: https://www.boost.org/doc/libs/1_78_0/doc/html/boost_asio/example/cpp17/coroutines_ts/echo_server_with_default.cpp (the HTML docs do NOT link these examples)

It keeps complaining that the websocket connection field is missing the upgrade token, and I don't have a clue what this is about.

The source project, rsocket-js in here, seems to have transpiration misconfigured letting the default export for the RSocketTCPClient class declaration go under a default variable.

You workaround would then either to tweak the transpiler configuration in your own project or use just the default exported object as follows:

GraphQL subscription with Jetty 10 embedded

Asked 2021-Sep-16 at 12:40

My objective is to have a functional version of the latest Graphql-java mixed with jetty version 10.

I have done a lot of tests, using different methods, and now I am stuck with the difference of the WebSocket implementation (on Jetty) between the version 9.4 and 10.0.6.

To test the implementation I am working on the example from the graphQL repository sample.

My tests are on the subproject servlet-hello-world, where a simple graphQL subscription is done and working on jetty 9.4

I have updated gradle to use the latest version

ANSWER

Answered 2021-Sep-16 at 12:40

The old version of Jetty was websocket implementation neutral (core, javax.websocket, jetty native websocket, etc). That proved to be too complex when multiple implementations were being used at the same time.

The new Jetty 10+ implementation requires you to use the appropriate WebSocketServletContainerInitializer for the implementation you are using. (where is one of Javax, Jakarta, or Jetty)

Since it looks like you are using javax.websocket, here's the appropriate class to use.

Answered 2021-May-27 at 08:30

After some research I found that, this can be solved with the Flux itself. It is enough that we add startWith method to the Flux. As in the definition of the startWith method.

Prepend the given values before this Flux sequence.

So we prepend our Hello message to the start of the Flux and it will be published first.

I found this answer Connect NestJS to a websocket server

Implemented my client as what you would have in the first answer. Second answer vent over my head a bit. Now I have a problem with listeners. When the socket disconnects I want to reconnect again. As you can see in the example listeners are instantiated in the constructor. When I want to reconnect those listeners are not re-instantiated and I don't know how to achieve that. Or how to instantiate listeners in some other way? Or even how to destroy that service and build a new one?
