Hi, We are using web sockets (with wicket-native-core) on many pages in our application. After upgrade a Jetty from 9.4.12.v20180830 to a newer version 9.4.18.v20190429, I have found a different behaviour in application:
When user navigates to another page, a websocket connection is closed and AbstractWebSocketProcessor.onClose method is called. This causes broadcasting a message to connected page: broadcastMessage(new ClosedMessage(getApplication(), getSessionId(), key)); and leads to page deserialisation (from PageStore). I think something was changed in a new version of Jetty, because in the previous used version this was not called. Maybe because of this: https://github.com/eclipse/jetty.project/issues/3835 https://github.com/eclipse/jetty.project/commit/2383bf4974ba7d82109cedfc4a8e7693d106abf0 I believe that now it works correctly (as was designed) and onClose should be called. But I wonder how it can affect performance: almost every page navigation causes page deserialization (when it should occur only for back button or when some web socket message comes and application need to process it). Maybe this message should be send only when needed or maybe I should not care and current behaviour does not affect performance? -- Best regards, Daniel Stoch --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
