1# *-*- Mode: Python -*-* 2 3## 4# 5# General note concerning the use of guest agent interfaces: 6# 7# "unsupported" is a higher-level error than the errors that individual 8# commands might document. The caller should always be prepared to receive 9# QERR_UNSUPPORTED, even if the given command doesn't specify it, or doesn't 10# document any failure mode at all. 11# 12## 13 14## 15# 16# Echo back a unique integer value, and prepend to response a 17# leading sentinel byte (0xFF) the client can check scan for. 18# 19# This is used by clients talking to the guest agent over the 20# wire to ensure the stream is in sync and doesn't contain stale 21# data from previous client. It must be issued upon initial 22# connection, and after any client-side timeouts (including 23# timeouts on receiving a response to this command). 24# 25# After issuing this request, all guest agent responses should be 26# ignored until the response containing the unique integer value 27# the client passed in is returned. Receival of the 0xFF sentinel 28# byte must be handled as an indication that the client's 29# lexer/tokenizer/parser state should be flushed/reset in 30# preparation for reliably receiving the subsequent response. As 31# an optimization, clients may opt to ignore all data until a 32# sentinel value is receiving to avoid unnecessary processing of 33# stale data. 34# 35# Similarly, clients should also precede this *request* 36# with a 0xFF byte to make sure the guest agent flushes any 37# partially read JSON data from a previous client connection. 38# 39# @id: randomly generated 64-bit integer 40# 41# Returns: The unique integer id passed in by the client 42# 43# Since: 1.1 44# ## 45{ 'command': 'guest-sync-delimited', 46 'data': { 'id': 'int' }, 47 'returns': 'int' } 48 49## 50# @guest-sync: 51# 52# Echo back a unique integer value 53# 54# This is used by clients talking to the guest agent over the 55# wire to ensure the stream is in sync and doesn't contain stale 56# data from previous client.
