The previous commits narrowed use of QError to handle_qmp_command() and its helpers monitor_protocol_emitter(), build_qmp_error_dict(). Narrow it further to just the command handler call: instead of converting Error to QError throughout handle_qmp_command(), convert the QError gotten from the command handler to Error, and switch the helpers from QError to Error.

All QMP commands use the "new" handler interface (mhandler.cmd_new). Most HMP commands still use the traditional interface (mhandler.cmd), but a few use the "new" one. Complicates handle_user_command() for no gain, so I'm converting these to the traditional interface. For device_add, that's easy: just wrap the obvious hmp_device_add() around do_device_add(). monitor_user_noop() is now unused, drop it.

The asynchronous monitor command interface goes back to commit 940cc30d (Jan 2010). Added a third case to command execution. The hope back then according to the commit message was that all commands get converted to the asynchronous interface, killing off the other two cases. Didn't happen. The initial asynchronous commands balloon and info balloon were converted back to synchronous long ago (commit 96637bcd and d72f32), with commit messages calling the asynchronous interface "not fully working" and "deprecated". The only other user went away in commit 3b5704b2. New code generally uses synchronous commands and asynchronous events. What exactly is still "not fully working" with asynchronous commands? Well, here's a bug that defeats actual asynchronous use pretty reliably: the reply's ID is wrong (and has always been wrong) unless you use the command synchronously! To reproduce, we need an asynchronous command, so we have to go back before commit 3b5704b2. Run QEMU with spice: $ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio {"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}} Connect a spice client in another terminal: $ remote-viewer spice://localhost:5900 Set up a migration destination dummy in a third terminal: $ socat TCP-LISTEN:12345 STDIO Now paste the following into the QMP monitor: { "execute": "qmp_capabilities", "id": "i0" } { "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } } { "execute": "query-kvm", "id": "i2" } Produces two replies immediately, one to qmp_capabilities, and one to query-kvm: {"return": {}, "id": "i0"} {"return": {"enabled": false, "present": true}, "id": "i2"} Both are correct. Two lines of debug output from libspice-server not shown. Now EOF socat's standard input to make it close the connection. This makes the asynchronous client_migrate_info complete. It replies: {"return": {}} Bug: "id": "i1" is missing. Two lines of debug output from libspice-server not shown. Cherry on top: storage for the missing ID is leaked. Get rid of this stuff before somebody hurts himself with it.

Live migration with spice works like this today: (1) client_migrate_info monitor cmd (2) spice server notifies client, client connects to target host. (3) qemu waits until spice client connect is finished. (4) send over vmstate (i.e. main part of live migration). (5) spice handover to target host. (3) is implemented by making client_migrate_info a async monitor command. This is the only async monitor command we have. The original reason to implement this dance was that qemu did not accept new tcp connections while the incoming migration was running, so (2) and (4) could not be done in parallel. That issue was fixed long ago though. Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp connects while the incoming migration runs. Time to drop step (3). This patch does exactly that, by making the monitor command synchronous and removing the code needed to handle the async monitor command in ui/spice-core.c Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Pretending that QMP doesn't understand a command merely because we are not in the right mode doesn't help first-time users figure out what to do to correct things. Although the documentation for QMP calls out capabilities negotiation, we should also make it clear in our error messages what we were expecting. With this patch, I now get the following transcript: $ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults {"QMP": {"version": {"qemu": {"micro": 93, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}} {"execute":"huh"} {"error": {"class": "CommandNotFound", "desc": "The command huh has not been found"}} {"execute":"quit"} {"error": {"class": "CommandNotFound", "desc": "Expecting capabilities negotiation with 'qmp_capabilities' before command 'quit'"}} {"execute":"qmp_capabilities"} {"return": {}} {"execute":"qmp_capabilities"} {"error": {"class": "CommandNotFound", "desc": "Capabilities negotiation is already complete, command 'qmp_capabilities' ignored"}} {"execute":"quit"} {"return": {}} {"timestamp": {"seconds": 1429110729, "microseconds": 181935}, "event": "SHUTDOWN"} Signed-off-by: NEric Blake <eblake@redhat.com> Tested-By: NKashyap Chamarthy <kchamart@redhat.com> Reviewed-by: NPaulo Vital <paulo.vital@profitbricks.com> Reviewed-by: NJohn Snow <jsnow@redhat.com> Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com>

2ed1ebcf "timer: replace time() with QEMU_CLOCK_HOST" broke compile when configured with --enable-profiler. Turned out the profiler has been broken for a while. This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode. This also fixes the compile error. This changes profile_getclock() to return nanoseconds rather than CPU ticks as the "profile" HMP command prints seconds and there is no platform-independent way to get ticks-per-second rate. Since TCG is quite slow and get_clock() returns nanoseconds (fine enough), this should not affect precision much. This removes unused qemu_time_start and tlb_flush_time.

monitor_read_bdrv_key_start() does several things: 1. If no key is needed, call completion_cb() and succeed 2. If we're in QMP context, call qerror_report_err() and fail 3. Start reading the key in the monitor. This is two things too many. Inline 1. and 2. into its callers monitor_read_block_device_key() and usb_msd_realize_storage(). Since monitor_read_block_device_key() only ever runs in HMP context, drop 2. there. The next commit will clean up the result in usb_msd_realize_storage().

Remove the temptation: drop the wrapper and open-code the (trivial) error handling instead. Replace the open-coded qerror_report_err() by error_report_err() in places that already use error_report().
