- Queued RPC calls would cause crashes due to invalid pointers to request/response and/or controller; this has been fixed
- PbRpcController now takes ownership of request and response messages and
will delete them when it itself is being deleted
- This design mandates that request and response messages for each RPC call
have to be allocated on the heap.
- The convention for the Closure 'done' call now is to allocate and pass a
pointer to the controller object to it which will delete it after use;
this requires that controller itself be also allocated on the heap
(NOTE: this is just a convention - not mandatory)
- All existing RPC calls (in portgroup.cpp) have been changed to follow the
above convention
- Reordering of queued RPC calls has been fixed
- PortManager is now destroyed at exit; because of this fix the per port temporary capture files are auto-removed at exit
- WinPcapPort destructor no longer deletes the monitor threads because the parent class PcapPort already does it
- Capture does not automatically (and incorrectly) stop after one packet if started immediately after a View Capture operation
- User is prompted to stop transmit on a port first if he tries to apply configuration changes on a port in 'transmit' state
