Hi. Why does crash "socket.close" when it called from second thread?
server.nim:
...
type
Server* = ref object
socket: AsyncSocket
...
...
...
proc newServer*(): Server =
Server(
socket: nil,
...
)
proc loopThr(server: Server, serverPort: int) =
server.socket = newAsyncSocket()
server.started = true
server.socket.bindAddr(serverPort.Port)
server.socket.listen()
server.loopTask = loop(server)
waitFor server.loopTask
proc start*(server: Server, serverPort: int) =
spawn loopThr(server, serverPort)
sleep(250)
...
...
proc stop*(server: Server) =
server.started = false
server.clients.setLen(0)
if server.loopTask != nil:
server.loopTask.complete()
server.loopTask = nil
server.socket.close()
server.socket = nil
main.nim:
...
var srv* {.threadvar.}: Server
srv = newServer()
srv.start(port)
srv.stop()
...
exception:
