Class MultiUserChatServiceImpl

  • All Implemented Interfaces:
    ClusterEventListener, DiscoInfoProvider, DiscoItemsProvider, ServerItemsProvider, MultiUserChatService, XMPPServerListener, org.xmpp.component.Component
    public class MultiUserChatServiceImpl
extends Object
implements org.xmpp.component.Component, MultiUserChatService, ServerItemsProvider, DiscoInfoProvider, DiscoItemsProvider, XMPPServerListener, ClusterEventListener
    Implements the chat server as a cached memory resident chat server. The server is also responsible for responding Multi-User Chat disco requests as well as removing inactive users from the rooms after a period of time and to maintain a log of the conversation in the rooms that require to log their conversations. The conversations log is saved to the database using a separate process.

    Temporary rooms are held in memory as long as they have occupants. They will be destroyed after the last occupant left the room. On the other hand, persistent rooms are always present in memory even after the last occupant left the room. In order to keep memory clean of persistent rooms that have been forgotten or abandoned this class includes a clean up process. The clean up process will remove from memory rooms that haven't had occupants for a while. Moreover, forgotten or abandoned rooms won't be loaded into memory when the Multi-User Chat service starts up.

      • addIQHandler

        public void addIQHandler​(IQHandler iqHandler)
        Description copied from interface: MultiUserChatService
        Add a IQHandler to MUC rooms and services. If the IQHandler only supports one or other, it should quietly ignore it.
        Specified by:
        addIQHandler in interface MultiUserChatService
        Parameters:
        iqHandler - the IQ handler to add

        public void setDescription​(String desc)

      • processPacket

        public void processPacket​(org.xmpp.packet.Packet packet)
        Specified by:
        processPacket in interface org.xmpp.component.Component

      • processVCardResponse

        public void processVCardResponse​(@Nonnull
                                 org.xmpp.packet.IQ response)
        Processes a VCard response stanza that is supposedly sent to an occupant of a room as a result of that occupant having requested the VCard of another occupant earlier. VCard processing in MUC rooms depends on a bit of a hack: most clients of requestees cannot process a request for a VCard themselves (see XEP-0054). Instead, the request is rerouted to the bare JID of the requestee, which is responded to by its home server. MUCRoom.sendPrivatePacket(Packet, MUCRole) implements this rerouting. The response from the home server is then processed by this method. It needs special care as its 'from' address is a bare JID (and thus not directly related to a single occupant).
        Parameters:
        response - An IQ stanza that should be a response to an earlier VCard request.

      • processRegularStanza

        public void processRegularStanza​(org.xmpp.packet.Packet packet)
                          throws UnauthorizedException,
                                 PacketException
        This method does all stanza routing in the chat server for 'regular' MUC stanzas. Packet routing is actually very simple:
        • Discover the room the user is talking to
        • If the room is not registered and this is a presence "available" packet, try to join the room
        • If the room is registered, and presence "unavailable" leave the room
        • Otherwise, rewrite the sender address and send to the room.
        Parameters:
        packet - The stanza to route
        Throws:
        UnauthorizedException
        PacketException

      • isPendingPingResponse

        public boolean isPendingPingResponse​(@Nonnull
                                     org.xmpp.packet.Packet stanza)
        Determines if a stanza is a client-generated response to an IQ Ping request sent by this server. A 'true' result of this method indicates that the client sending the IQ response is currently reachable.
        Parameters:
        stanza - The stanza to check
        Returns:
        true if the stanza is a response to an IQ Ping request sent by the server, otherwise false.

      • isDeliveryRelatedErrorResponse

        public boolean isDeliveryRelatedErrorResponse​(@Nonnull
                                              org.xmpp.packet.Packet stanza)
        Determines if a stanza is sent by (on behalf of) an entity that MUC room believes to be an occupant when they've left: a 'ghost' occupant For message and presence stanzas, the delivery errors as defined in section 18.1.2 of XEP-0045 are used. For IQ stanzas, these errors may be due to lack of client support rather than a vanished occupant. Therefore, IQ stanzas will only return 'true' when they are an error response to an IQ Ping request sent by this server.
        Parameters:
        stanza - The stanza to check
        Returns:
        true if the stanza is a delivery related error response (from a 'ghost user'), otherwise false.

        Description copied from interface: MultiUserChatService
        Obtains a chatroom by name. A chatroom is created for that name if none exists and the user has permission. The user that asked for the chatroom will be the room's owner if the chatroom was created. Note that when obtaining a room instance using this method, the caller should take responsibility to make sure that any changes to the instance will become visible to other cluster nodes (which is done by invoking MultiUserChatService.syncChatRoom(MUCRoom). Where appropriate, the caller should apply mutex (as returned by MultiUserChatService.getChatRoomLock(String)) to control concurrent access to the returned instance.
        Specified by:
        getChatRoom in interface MultiUserChatService
        Parameters:

      • joinedCluster

        public void joinedCluster()
        Description copied from interface: ClusterEventListener
        Notification event indicating that this JVM is now part of a cluster. At this point the XMPPServer.getNodeID() holds the new nodeID value.

        When joining the cluster as the senior cluster member the ClusterEventListener.markedAsSeniorClusterMember() event will be sent right after this event.

        At this point the CacheFactory holds clustered caches. That means that modifications to the caches will be reflected in the cluster. The clustered caches were just obtained from the cluster and no local cached data was automatically moved.

        It is generally advisable that implementations of this method:
        • enrich clustered cache data, by (re)adding data from this JVM/cluster node to relevant caches
        • invoke applicable event listeners, to reflect changes in availability of data on other cluster nodes.
        Specified by:
        joinedCluster in interface ClusterEventListener

      • joinedCluster

        public void joinedCluster​(byte[] nodeID)
        Description copied from interface: ClusterEventListener
        Notification event indicating that another JVM is now part of a cluster.

        At this point the CacheFactory of the new node holds clustered caches. That means that modifications to the caches of this JVM will be reflected in the cluster and in particular in the new node.

        Specified by:
        joinedCluster in interface ClusterEventListener
        Parameters:
        nodeID - ID of the node that joined the cluster.

      • leftCluster

        public void leftCluster()
        Description copied from interface: ClusterEventListener
        Notification event indicating that this JVM is no longer part of the cluster. This could happen when disabling clustering support, removing the enterprise plugin that provides clustering support or connection to cluster got lost.

        Moreover, if we were in a "split brain" scenario (ie. separated cluster islands) and the island were this JVM belonged was marked as "old" then all nodes of that island will get the left cluster event and joined cluster events. That means that caches will be reset and thus will need to be repopulated again with fresh data from this JVM. This also includes the case where this JVM was the senior cluster member and when the islands met again then this JVM stopped being the senior member.

        At this point the CacheFactory holds local caches. That means that modifications to the caches will only affect this JVM. It is generally advisable that implementations of this method:

        • restore relevant caches content, by repopulating the caches with data from this JVM/cluster node
        • invoke applicable event listeners, to reflect changes in availability of data on other cluster nodes.
        Specified by:
        leftCluster in interface ClusterEventListener

      • leftCluster

        public void leftCluster​(byte[] nodeID)
        Description copied from interface: ClusterEventListener
        Notification event indicating that another JVM is no longer part of the cluster. This could happen when disabling clustering support, removing the enterprise plugin that provides clustering support or connection to cluster got lost.

        Moreover, if we were in a "split brain" scenario (ie. separated cluster islands) and the island were the other JVM belonged was marked as "old" then all nodes of that island will get the left cluster event and joined cluster events. That means that caches will be reset and thus will need to be repopulated again with fresh data from this JVM. This also includes the case where the other JVM was the senior cluster member and when the islands met again then the other JVM stopped being the senior member.

        At this point the CacheFactory of the leaving node holds local caches. That means that modifications to the caches of this JVM will not affect the leaving node but other cluster members. It is generally advisable that implementations of this method invoke applicable event listeners, to reflect changes in availability of data (related to the node that left). Often, this action is orchestrated by only one of the remaining cluster nodes: the senior member.

        Specified by:
        leftCluster in interface ClusterEventListener
        Parameters:
        nodeID - ID of the node that is left the cluster.

      • markedAsSeniorClusterMember

        public void markedAsSeniorClusterMember()
        Description copied from interface: ClusterEventListener
        Notification event indicating that this JVM is now the senior cluster member. This could either happen when initially joining the cluster or when the senior cluster member node left the cluster and this JVM was marked as the new senior cluster member.

        Moreover, in the case of a "split brain" scenario (ie. separated cluster islands) each island will have its own senior cluster member. However, when the islands meet again there could only be one senior cluster member so one of the senior cluster members will stop playing that role. When that happens the JVM no longer playing that role will receive the ClusterEventListener.leftCluster() and ClusterEventListener.joinedCluster() events.

        Specified by:
        markedAsSeniorClusterMember in interface ClusterEventListener
