Raw Normal View History

Added ability for turtle router to take client services - new class RsTurtleClientService, from which should inherit the services - turtle serialisation takes client services for deserialising - added a client to p3turtle::monitorTunnels() - added a generic turtle item to pass on arbitrary data Moved ftServer as a subclass of RsTurtleClientService. - moved file transfer items that inherited from RsTurtleGenericTunnelItem into a separate file - moved deserialisation triage into ftServer - moved sending/receiving methods in ftServer (much less code, much more consistent!) One bug remains: the TR cannot work as a server. Changes should be 100% backward compatible. git-svn-id: http://svn.code.sf.net/p/retroshare/code/branches/v0.5-GenericTunneling@6293 b45a01b8-16f6-495d-af2f-9b41ad6348cc
