2013-10-10qemu-ga: Extend 'guest-info' command to expose flag 'success-response'Mark Wu1-0/+1
Now we have several qemu-ga commands not returning response on success. It has been documented in qga/qapi-schema.json already. This patch exposes the 'success-response' flag by extending 'guest-info' command. With this change, the clients can handle the command response more flexibly.

2013-10-10qemu-ga: Add interface to traverse the qmp command list by QmpCommandMark Wu1-23/+15
In the original code, qmp_get_command_list is used to construct a list of all commands' name. To get the information of all qga commands, it traverses the name list and search the command info with its name. So it can cause O(n^2) in the number of commands. This patch adds an interface to traverse the qmp command list by QmpCommand to replace qmp_get_command_list. It can decrease the complexity from O(n^2) to O(n).

2012-05-15qemu-ga: align versioning with QEMU_VERSIONMichael Roth1-1/+1
Previously qemu-ga version was defined seperately. Since it is aligned with QEMU releases, use QEMU_VERSION instead. This also implies the version bump for 1.1[-rcN] release of qemu-ga.

2012-03-12qemu-ga: add guest-sync-delimitedMichael Roth1-0/+6
guest-sync leaves it as an exercise to the user as to how to reliably obtain the response to guest-sync if the client had previously read in a partial response (due qemu-ga previously being restarted mid-"sentence" due to reboot, forced restart, etc). qemu-ga handles this situation on its end by having a client precede their guest-sync request with a 0xFF byte (invalid UTF-8), which qemu-ga/QEMU JSON parsers will treat as a flush event. Thus we can reliably flush the qemu-ga parser state in preparation for receiving the guest-sync request. guest-sync-delimited provides the same functionality for a client: when a guest-sync-delimited is issued, qemu-ga will precede it's response with a 0xFF byte that the client can use as an indicator to flush its buffer/parser state in preparation for reliably receiving the guest-sync-delimited response. It is also useful as an optimization for clients, since, after issuing a guest-sync-delimited, clients can safely discard all stale data read from the channel until the 0xFF is found.

2012-02-23qemu-ga: separate out common commands from posix-specific onesMichael Roth1-0/+73
Many of the current RPC implementations are very much POSIX-specific and require complete re-writes for Windows. There are however a small set of core guest agent commands that are common to both, and other commands such as guest-file-* which *may* be portable. So we introduce commands.c for the latter, and will rename guest-agent-commands.c to commands-posix.c in a future commit. Windows implementations will go in commands-win32.c, eventually.
