This patch adds the definition of the wire format for RPC calls
and implementation of the RPC client & server code
Signed-off-by: Stefan Berger <stefanb@us.ibm.com>
This defines the wire format for the new virDomainUpdateDeviceFlags()
API, and implements the server & client side of the marshalling code.
* daemon/remote.c: Server side dispatch for virDomainUpdateDeviceFlags
* src/remote/remote_driver.c: Client side serialization for
virDomainUpdateDeviceFlags
* src/remote/remote_protocol.x: Define wire format for
virDomainUpdateDeviceFlags
* daemon/remote_dispatch_args.h, daemon/remote_dispatch_prototypes.h,
daemon/remote_dispatch_table.h, src/remote/remote_protocol.c,
src/remote/remote_protocol.h: Re-generate code
This wires up the remote driver to handle the new events APIs.
The public API allows an application to request a callback filters
events to a specific domain object, and register multiple callbacks
for the same event type. On the wire there are two strategies for
this
- Register multiple callbacks with the remote daemon, each
with filtering as needed
- Register only one callback per event type, with no filtering
Both approaches have potential inefficiency. In the first scheme,
the same event gets sent over the wire many times if multiple
callbacks are registered. With the second scheme, unneccessary
events get sent over the wire if a per-domain filter is set on
the client. The second scheme is far easier to implement though,
so this patch takes that approach.
* daemon/dispatch.h: Don't export remoteRelayDomainEvent since it
is no longer needed for unregistering callbacks, instead the
unique callback ID is used
* daemon/libvirtd.c, daemon/libvirtd.h: Track and unregister
callbacks based on callback ID, instead of function pointer
* daemon/remote.c: Switch over to using virConnectDomainEventRegisterAny
instead of legacy virConnectDomainEventRegister function. Refactor
remoteDispatchDomainEventSend() to cope with arbitrary event types
* src/driver.h, src/driver.c: Move verify() call into source file
instead of header, to avoid polluting the global namespace with
the verify function name
* src/remote/remote_driver.c: Implement new APIs for event
registration. Refactor processCallDispatchMessage() to cope
with arbitrary incoming event types. Merge remoteDomainQueueEvent()
into processCallDispatchMessage() to avoid duplication of code.
Rename remoteDomainReadEvent() to remoteDomainReadEventLifecycle()
* src/remote/remote_protocol.x: Define wire format for the new
virConnectDomainEventRegisterAny and virConnectDomainEventDeregisterAny
functions
This defines the wire protocol for the new API
* src/remote/remote_protocol.x: Wire protocol definition
* src/remote/remote_driver.c,daemon/remote.c: Client and server
side implementation
* daemon/remote_dispatch_args.h, daemon/remote_dispatch_prototypes.h,
daemon/remote_dispatch_table.h, src/remote/remote_protocol.c,
src/remote/remote_protocol.h: Re-generate from remote_protocol.x
* src/remote/remote_protocol.x: Define wire protocol format
for virDomainGetJobInfo API
* src/remote/remote_driver.c, daemon/remote.c: Implement client
and server marshalling code for virDomainGetJobInfo()
* daemon/remote_dispatch_args.h, daemon/remote_dispatch_prototypes.h
daemon/remote_dispatch_ret.h, daemon/remote_dispatch_table.h,
src/remote/remote_protocol.c, src/remote/remote_protocol.h: Rebuild
files from src/remote/remote_protocol.x
Use a dynamically sized xdr_array to pass memory stats on the wire. This
supports the addition of future memory stats and reduces the message size
since only supported statistics are returned.
* src/remote/remote_protocol.x: provide defines for the new entry point
* src/remote/remote_driver.c daemon/remote.c: implement the client and
server side
* daemon/remote_dispatch_args.h daemon/remote_dispatch_prototypes.h
daemon/remote_dispatch_ret.h daemon/remote_dispatch_table.h
src/remote/remote_protocol.c src/remote/remote_protocol.h: generated
stubs
* src/remote/remote_protocol.x: update with new entry point
* daemon/remote.c: add the new server dispatcher
* daemon/remote_dispatch_args.h daemon/remote_dispatch_prototypes.h
daemon/remote_dispatch_ret.h daemon/remote_dispatch_table.h
src/remote/remote_protocol.c src/remote/remote_protocol.h: regenerated
Implementation of tunnelled migration, using a Unix Domain Socket
on the qemu backend. Note that this requires very new versions of
qemu (0.10.7 at least) in order to get the appropriate bugfixes.
