Odd behavior of React events

[bruce-ricard]

I added a simple React event to my super basic eliom-distillery generated server (https://github.com/bruce-ricard/miscellaneous/blob/serverevent/eliom-client-file/test/test.eliom).

The added code is from lines 30 to 50. I created a react event which sends a new integer to the channel every second (line 35). I add a listener to this even (line 48) which just prints what it finds on the channel.

If you run the code with run test.byte, you can see in the logs that the React code works well: it sends the data to the channel, it is received and printed. Now, hit the server curl localhost:8080 , and suddenly the consumer of the channel stops printing.

I am not sure if this is a bug or if there's something I don't understand about how this works. I tried with React and Lwt_react, they both have the same behavior.

It is possible that the connections from other clients trigger a garbage collection and that the reactive values are garbage-collected. You have to keep a reference to them somewhere.
