5c366a8a3d Fix hanging user monitor when using balloon command
Arghh... Adding missing S-O-B

Hi Anthony.  I wonder if there was a problem when importing my async
command handler patchset.  Since the 'balloon' command completes
immediately, it must call the completion callback before returning.
That call was missing but is added by the patch below.

068b332a65 Monitor: Report more than one error in handlers
Handlers can generate only one error in a call, we let the

get the first generated error.

10e4f606ec Monitor: Debug stray prints the right way
QObject Monitor handlers should not call any Monitor print
function: they should only build objects, printing is done
by common code.

Current QMP code will ignore such calls, as we can't send
garbage to clients, additionally it will also emit an
undefined error on the assumption that print calls usually
report errors.

However, the right way to deal with this is to rely on a
return code. This has been fixed by other commit already.

Now, this commit drops the error from monitor_vprintf() and
adds a better debugging mechanism for those 'stray' prints:
we count them if debug is enabled and let the developer know
if a QObject handler is trying to print anything.

bb89c2e901 Monitor: Audit handler return
This commit verifies the following two rules specified by
Markus Armbruster:

1. If the handler returns failure, it must have passed an error.

   If it didn't, it's broken. Report an internal error to the client,
   and report the bug to the programmer.

2. If the handler returns success, it must not have passed an error.

   If it did, it's broken. Report the error to the client, and report
   the bug to the programmer.

97536cffbf Monitor: Introduce cmd_new_ret()
In order to implement the new error handling and debugging
mechanism for command handlers, we need to change the cmd_new()
callback to return a value.

This commit introduces cmd_new_ret(), which returns a value and
will be used only temporarily to handle the transition from
cmd_new().

That is, as soon as all command handlers are ported to cmd_new_ret(),
it will be renamed back to cmd_new() and the new error handling
and debugging mechanism will be added on top of it.

47116d1c90 QMP: Don't leak on connection close
QMP's chardev event callback doesn't call
json_message_parser_destroy() on CHR_EVENT_CLOSED. As the call
to json_message_parser_init() on CHR_EVENT_OPENED allocates memory,
we'are leaking on close.

Fix that by just calling json_message_parser_destroy() on
CHR_EVENT_CLOSED.

27a749fb73 QError: Don't abort on multiple faults
Ideally, Monitor code should report an error only once and
return the error information up the call chain.

To assure that this happens as expected and that no error is
lost, we have an assert() in qemu_error_internal().

However, we still have not fully converted handlers using
monitor_printf() to report errors. As there can be multiple
monitor_printf() calls on an error, the assertion is easily
triggered when debugging is enabled; and we will get a memory
leak if it's not.

The solution to this problem is to allow multiple faults by only
reporting the first one, and to release the additional error objects.

A better mechanism to report multiple errors to programmers is
underway.

4a7e1190df QMP: Introduce the qmp_capabilities command
This command will be used to enable QMP capabilities advertised
by the capabilities array.

Note that it will be mandatory to issue this command in order
to make QMP functional (although this behavior is not being
enforced by this commit).

Also, as we don't have any capabilities yet, the new command
doesn't accept any arguments. I will postpone the decision for
a format for this until we get our first capability.

Finally, this command is visible from the user Monitor too, in
the meaning that you can execute it but it won't do anything.
Making it only visible in QMP is beyond this series' goal, as
it requires changes in unrelated places.

ca9567e234 QMP: Add QEMU's version to the greeting message
With capability negotiation support clients will only have a chance
to check QEMU's version (ie. issue 'query-version') after the

It might be useful to clients to check QEMU's version before
negotiating features, though.

To allow that, this commit adds the QEMU's version object to the
greeting message.

Not really sure this is needed, but doesn't hurt anyway.

625a5befc2 virtio: Add memory statistics reporting to the balloon driver
When using ballooning to manage overcommitted memory on a host, a system for
guests to communicate their memory usage to the host can provide information
that will minimize the impact of ballooning on the guests.  The current method
employs a daemon running in each guest that communicates memory statistics to a
host daemon at a specified time interval.  The host daemon aggregates this
information and inflates and/or deflates balloons according to the level of
host memory pressure.  This approach is effective but overly complex since a
daemon must be installed inside each guest and coordinated to communicate with
the host.  A simpler approach is to collect memory statistics in the virtio
balloon driver and communicate them directly to the hypervisor.

940cc30d0d New API for asynchronous monitor commands
Qemu has a number of commands that can operate asynchronously (savevm, migrate,
etc) and it will be getting more.  For these commands, the user monitor needs
to be suspended, but QMP monitors could continue to to accept other commands.
This patch introduces a new command API that isolates the details of handling
different monitor types from the actual command execution.

A monitor command can use this API by implementing the mhandler.cmd_async
handler (or info_async if appropriate).  This function is responsible for
submitting the command and does not return any data although it may raise
errors.  When the command completes, the QMPCompletion callback should be
invoked with its opaque data and the command result.

The process for submitting and completing an asynchronous command is different
for QMP and user monitors.  A user monitor must be suspended at submit time and
resumed at completion time.  The user_print() function must be passed to the
QMPCompletion callback so the result can be displayed properly.  QMP monitors
are simpler.  No submit time setup is required.  When the command completes,
monitor_protocol_emitter() writes the result in JSON format.

This API can also be used to implement synchronous commands.  In this case, the
cmd_async handler should immediately call the QMPCompletion callback.  It is my
hope that this new interface will work for all commands, leading to a
drastically simplified monitor.c once all commands are ported.

f039a563f2 QMP: Emit asynchronous events on all QMP monitors
When using a control/QMP monitor in tandem with a regular monitor, asynchronous
messages can get lost depending on the order of the QEMU program arguments.
QEMU events issued by monitor_protocol_event() always go to cur_mon.  If the
user monitor was specified on the command line first (or it has ,default), the
message will be directed to the user monitor (not the QMP monitor).
Additionally, only one QMP session is currently able to receive async messages.

To avoid this confusion, scan through the list of monitors and emit the message
on each QMP monitor.
