Implemented with base64-encoded strings in qga json protocol. Glib portable GIOChannel is used for data I/O. Optinal stdin parameter of guest-exec command is now used as stdin content for spawned subprocess. If capture-output bool flag is specified, guest-exec redirects out/err file descriptiors internally to pipes and collects subprocess output. Guest-exe-status is modified to return this collected data to requestor in base64 encoding. Signed-off-by: Yuri Pudgorodskiy <yur@virtuozzo.com> Signed-off-by: Denis V.

# General note concerning the use of guest agent interfaces:
|
|
#
|
|
# "unsupported" is a higher-level error than the errors that individual
|
|
# commands might document. The caller should always be prepared to receive
|
|
# QERR_UNSUPPORTED, even if the given command doesn't specify it, or doesn't
|
|
# document any failure mode at all.

# @guest-sync-delimited:
|
|
#
|
|
# Echo back a unique integer value, and prepend to response a
|
|
# leading sentinel byte (0xFF) the client can check scan for.
|
|
#
|
|
# This is used by clients talking to the guest agent over the
|
|
# wire to ensure the stream is in sync and doesn't contain stale
|
|
# data from previous client. It must be issued upon initial
|
|
# connection, and after any client-side timeouts (including
|
|
# timeouts on receiving a response to this command).
|
|
#
|
|
# After issuing this request, all guest agent responses should be
|
|
# ignored until the response containing the unique integer value
|
|
# the client passed in is returned. Receival of the 0xFF sentinel
|
|
# byte must be handled as an indication that the client's
|
|
# lexer/tokenizer/parser state should be flushed/reset in
|
|
# preparation for reliably receiving the subsequent response. As
|
|
# an optimization, clients may opt to ignore all data until a
|
|
# sentinel value is receiving to avoid unnecessary processing of
|
|
# stale data.
|
|
#
|
|
# Similarly, clients should also precede this *request*
|

# This is used by clients talking to the guest agent over the

# and it is up to the client to handle stale whole or
|
|
# partially-delivered JSON text in such a way that this response
|
|
# can be obtained.
|
|
#
|
|
# In cases where a partial stale response was previously
|
|
# received by the client, this cannot always be done reliably.
|
|
# One particular scenario being if qemu-ga responses are fed

|
