Adapt the pt sul owner list to be an array, and define two different lists, one that acts like before and is the default for existing users, and another that has the ability to cooperate with systemwide suspend to restrict the interval spent suspended so that it will wake in time for the earliest thing on this wake-suspend sul list. Clean the api a bit and add lws_sul_cancel() that only needs the sul as the argument. Add a flag for client creation info to indicate that this client connection is important enough that, eg, validity checking it to detect silently dead connections should go on the wake-suspend sul list. That flag is exposed in secure streams policy so it can be added to a streamtype with "swake_validity": true Deprecate out the old vhost timer stuff that predates sul. Add a flag LWS_WITH_DEPRECATED_THINGS in cmake so users can get it back temporarily before it will be removed in a v4.2. Adapt all remaining in-tree users of it to use explicit suls. |

lws minimal ws client tx
This demonstrates a ws "publisher" to go with the minimal-ws-broker example.
Two threads are spawned that produce messages to be sent to the broker, via a local ringbuffer. Locking is provided to make ringbuffer access threadsafe.
When a nailed-up client connection to the broker is established, the ringbuffer is sent to the broker, which distributes the events to all connected clients.
build
$ cmake . && make
usage
This example connects to ws-server/minimal-ws-broker, so you need to build and run that in another terminal.
$ ./lws-minimal-ws-client-tx
