rework global sync event for whiteboard syncing from server-side object List #491

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
to synchronize the Object List once a Client enters a Room, all other Users
have to wait.

This synchronization must also work if two users concurrently enter a room.
In this situation the sync-event has to deal with all sync events.

The synchronization must also work if somebody is in another
synchronization dialog, for example if he loads a stored image or WML-File.
In this situation the synchronization process has to wait until previous
sync-events are completed.

there is a logical error in the implementation.
Users can load multiple instance of Images parallel. In the current 
implementation
only one user at a time can be synchronized.
Changing it to allow Simultaneous actions on the whiteboard will break this 
system.

the sync process of the initial loading is alright, cause here we got only _one_
object, which is loaded into one user, in the image loading process _one_ image 
will
be loaded into every connected client, so every image created multiple 
syncronization
processes.

At Client rev 1529
   Server rev 1527

Sync modifications not quite clean
elimination of addSWFToLayerHistory and addImageToLayerHistory left references 
to   
these functions in client code
  modules.conference.whiteboard.base
    baseDraw.lzx
    remoteWhiteboard.lzx
If you update the SVN repository with the proper function assignments I will be 
happy to test.
