33#
34# Echo back a unique integer value, and prepend to response a
35# leading sentinel byte (0xFF) the client can check scan for.
36#
37# This is used by clients talking to the guest agent over the
38# wire to ensure the stream is in sync and doesn't contain stale
39# data from previous client. It must be issued upon initial
40# connection, and after any client-side timeouts (including
41# timeouts on receiving a response to this command).
42#
43# After issuing this request, all guest agent responses should be
44# ignored until the response containing the unique integer value
45# the client passed in is returned. Receival of the 0xFF sentinel
46# byte must be handled as an indication that the client's
47# lexer/tokenizer/parser state should be flushed/reset in
48# preparation for reliably receiving the subsequent response. As
49# an optimization, clients may opt to ignore all data until a
50# sentinel value is receiving to avoid unnecessary processing of
51# stale data.
52#
53# Similarly, clients should also precede this *request*
54# with a 0xFF byte to make sure the guest agent flushes any
55# partially read JSON data from a previous client connection.

73# wire to ensure the stream is in sync and doesn't contain stale
74# data from previous client. All guest agent responses should be
75# ignored until the provided unique integer value is returned,
76# and it is up to the client to handle stale whole or
77# partially-delivered JSON text in such a way that this response
78# can be obtained.
79#
80# In cases where a partial stale response was previously
81# received by the client, this cannot always be done reliably.
82# One particular scenario being if qemu-ga responses are fed
83# character-by-character into a JSON parser. In these situations,
84# using guest-sync-delimited may be optimal.
85#
86# For clients that fetch responses line by line and convert them
87# to JSON objects, guest-sync should be sufficient, but note that
88# in cases where the channel is dirty some attempts at parsing the
89# response may result in a parser error.
