[cp-patches] [RFA/JDWP] CommandSet interface and PacketProcessor

[Aaron Luchko]

Hello, I've been working with Keith Seitz to help with jdwp. This patch
adds the functionality for PacketProcessor to act on a given packet from
the debugger via CommandSet objects along with the CommandSet interface.

I've left the commented out list of different CommandSets added to the
HashTable in the constructor to demonstrate how they will be stored.
The CommandSet objects will carry out all the work associated with a
given command (ie finding values of variables, setting event requests)
then write the data for the response to the output stream.

The reason for runCommand returning a boolean to indicate a transport
layer shutdown is the commands
http://java.sun.com/j2se/1.5.0/docs/guide/jpda/jdwp/jdwp-protocol.html#JDWP_VirtualMachine_Dispose
and
http://java.sun.com/j2se/1.5.0/docs/guide/jpda/jdwp/jdwp-protocol.html#JDWP_VirtualMachine_Exit
require the transport layer to be shutdown and a reply packet to still
be sent. After receiving sending the shutdown reply packet it will first
shutdown the transport layer, and then its own thread. At this point the
intent is that the appropriate CommandSet will take care of all the
other associated actions such as canceling event requests and shutting
down other threads in the VM.
