Re: [libvirt] [PATCH v4 6/8] Qemu remote protocol.



On 07/07/2010 03:33 PM, Chris Lalancette wrote:
Since we are adding a new "per-hypervisor" protocol, we
make it so that the qemu remote protocol uses a new
PROTOCOL and PROGRAM number.  This allows us to easily
distinguish it from the normal REMOTE protocol.

This necessitates changing the proc in remote_message_header
from a "remote_procedure" to an "unsigned", which should
be the same size (and thus preserve the on-wire protocol).

Changes since v1:
  - Fixed up a couple of script problems in remote_generate_stubs.pl
  - Switch an int flag to a bool in dispatch.c

Changes since v2:
  - None

Changes since v3:
  - Change unsigned proc to signed proc, to conform to spec

Sorry for not noticing sooner, but this breaks 'make check' if you have dwarves installed:

I'll be checking the trivial fix under the obvious rule.
