From 42074a9d4d4cf0b7c2a3210de424f9b11268abb4 Mon Sep 17 00:00:00 2001 From: Michael Roth Date: Thu, 19 Jan 2012 22:19:27 -0600 Subject: [PATCH] qemu-ga: separate out common commands from posix-specific ones 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. --- Makefile.objs | 2 +- qga/commands.c | 73 ++++++++++++++++++++++++++++++++++++++ qga/guest-agent-commands.c | 59 +----------------------------- qga/guest-agent-core.h | 1 + 4 files changed, 76 insertions(+), 59 deletions(-) create mode 100644 qga/commands.c diff --git a/Makefile.objs b/Makefile.objs index 004db82e93..49ab82bc7e 100644 --- a/Makefile.objs +++ b/Makefile.objs @@ -424,7 +424,7 @@ common-obj-y += qmp.o hmp.o ###################################################################### # guest agent -qga-nested-y = guest-agent-commands.o guest-agent-command-state.o +qga-nested-y = commands.o guest-agent-commands.o guest-agent-command-state.o qga-nested-y += channel-posix.o qga-obj-y = $(addprefix qga/, $(qga-nested-y)) qga-obj-y += qemu-ga.o qemu-sockets.o module.o qemu-option.o diff --git a/qga/commands.c b/qga/commands.c new file mode 100644 index 0000000000..b27407d5d7 --- /dev/null +++ b/qga/commands.c @@ -0,0 +1,73 @@ +/* + * QEMU Guest Agent common/cross-platform command implementations + * + * Copyright IBM Corp. 2012 + * + * Authors: + * Michael Roth + * + * This work is licensed under the terms of the GNU GPL, version 2 or later. + * See the COPYING file in the top-level directory. + */ + +#include +#include "qga/guest-agent-core.h" +#include "qga-qmp-commands.h" +#include "qerror.h" + +/* Note: in some situations, like with the fsfreeze, logging may be + * temporarilly disabled. if it is necessary that a command be able + * to log for accounting purposes, check ga_logging_enabled() beforehand, + * and use the QERR_QGA_LOGGING_DISABLED to generate an error + */ +void slog(const gchar *fmt, ...) +{ + va_list ap;
