Alexis Deruelle 6412d73a5a Fix port availability test (#333) ... * Let OS allocate port number Port availability might be tricky if some port is already in use on the 'all' interface '0.0.0.0'. The proposed solution is to let the OS allocate the port for us using 0 as port specifier : - first create a server instance to allocate a port number - save port number - close the server - return the port number to the caller This should be safe granted the OS doesn't reuse the port numbers on consecutive port allocations. see : - about Node.js Net module : https://nodejs.org/docs/latest-v12.x/api/net.html#net_server_listen_port_host_backlog_callback - about safety around reusing port number : https://unix.stackexchange.com/a/132524 Signed-off-by: Alexis Deruelle <alexis.deruelle@gmail.com>		2020-05-05 07:31:58 +03:00
