Kompos tests are sometimes failing on Travis because the old server is still running/shutting down.
So, there is some race.
One problem might be that there is a reuse timeout.
If there is no other race/promise not handled correctly, we might need to look into using:
setReuseAddress(true)
on the socket.Instead of using
setReuseAddress(true)
, I am switching to using ephemeral ports, i.e., random ports when the normal ones are in use.The port numbers are reported in standard out and are parsed out by the tests.
In the frontend code, I am using a JSON request to retrieve them via HTTP.
