Combine join and state transfer ------------------------------- Key: JGRP-236 URL: http://jira.jboss.com/jira/browse/JGRP-236 Project: JGroups Issue Type: Feature Request Affects Versions: 2.2.8, 2.2.9, 2.3, 2.2.9.1, 2.2.9.2 Reporter: Bela Ban Assigned To: Vladimir Blagojevic Fix For: 2.6 Add an additional connect(String group_name, boolean fetch_state, String state_id) method to Channel, so that we can combine joining and state transfer into 1 operation. This also requires only 1 FLUSH phase. The state would be returned either via pulling with Channel.receive() or pushing the setState() method in a registered Receiver/MessageListener. - The JOIN_REQ contains the boolean - The algorithm in GMS is the same as the two described above, except that before multicasting the new view and sending the JOIN_RSPs and LEAVE_RSPs, we ask the application for its state (GET_APPLSTATE) and when received (GET_APPLSTATE_OK), we send it back to the joining member(s), and the RESUME sending messages
