Since gettimeofday() is used in this header file as a macro define,
include the function's define header file, to avoid compile warning
when other file include os-posix.h.

qapi-schema.json has been split into three smaller JSON files in qapi/.
Add them as dependencies for the code generation in the Makefile, so
changes to them will result in a rebuilt of all QAPI-dependent code.

From: Wenchao Xia <wenchaoqemu@gmail.com>
qapi-event.py will parse the schema and generate qapi-event.c, then
the API in qapi-event.c can be used to handle events in qemu code.
All API have prefix "qapi_event".
The script mainly includes two parts: generate API for each event
define, generate an enum type for all defined events.
Since in some cases the real emit behavior may change, for example,
qemu-img would not send a event, a callback layer is used to
control the behavior. As a result, the stubs at compile time
can be saved, the binding of block layer code and monitor code
will become looser.

From: Paolo Bonzini @ 2014-06-18 6:43 UTC (permalink / raw)
To: qemu-devel; +Cc: wenchaoqemu, lcapitulino
From: Wenchao Xia <wenchaoqemu@gmail.com>
In order to let event defines use existing types later, instead of
redefine new ones, some old type defines for spice and vnc are changed,
and BlockErrorAction is moved from block.h to qapi schema. Note that
BlockErrorAction is not merged with BlockdevOnError.
At this point, VncInfo is not made a child of VncBasicInfo, because
VncBasicInfo has mandatory fields where VncInfo makes them optional.

From: Wenchao Xia <wenchaoqemu@gmail.com>
The monitor is now hooked on the new event mechanism, so that later
patches can convert event callers one by one. Most code are copied from
old monitor_protocol_* functions with some modification.
Note that two build time warnings will be raised after this patch. One is
caused by no caller of monitor_qapi_event_throttle(), the other one is
caused by QAPI_EVENT_MAX = 0. They will be fixed automatically after
full event conversion later.

Since BLOCK_JOB_COMPLETED, BLOCK_JOB_CANCELLED, BLOCK_JOB_READY are
related, convert them in one patch. The block_job_event_* functions
are used to keep encapsulation of BlockJob structure.

To: qemu-devel; +Cc: wenchaoqemu, lcapitulino
From: Wenchao Xia <wenchaoqemu@gmail.com>
SPICE_INITIALIZED, SPICE_CONNECTED, SPICE_DISCONNECTED and
SPICE_MIGRATE_COMPLETED are converted in one patch, since they
use some common functions. inet_strfamily() is removed since no
callers exist anymore.
Note that there is no existing doc for SPICE_MIGRATE_COMPLETED
in docs/qmp/qmp-events.txt before this patch.

Make the mux always go through qemu_chr_fe_write, so that we'll get
the mutex for the underlying chardev.

This will let threads other than the I/O thread raise QMP events.
GIOChannel is thread-safe, and send and receive state is usually
well-separated. The only driver that requires some care is the
pty driver, where some of the state is shared by the read and write
sides. That state is protected with the chr_write_lock too.

Event emission must be protected by a mutex because of access to
the shared rate-limiting state, and to guard against concurrent
monitor "hot-plug" by means of human-monitor-command.

Using unsigned instead of QAPIEvent works around the include issue,
and also fix the type cast issue in implemention function that Eric

Still didn't pick up on my suggestion of at least having a comment in
the new file; but I can live with it.

Stale comment, given that earlier in the series we added a workaround to
avoid the warning in the first place.

Not quite as strong as wording in other locations about not parsing the
value because it is allowed to change; but you could change that in a
followup if desired. I'm okay with this commit going in as written.

At this point, if you need to clean it up in a followup patch instead of
delaying the series, I can live with it.

You could drop this comment; the one several lines earlier states pretty
much the same thing. But saving it for a followup is okay with me.

I'll resume my review tomorrow on Paolo's thread-safety patches, but if
Luiz is ready to pull these into his staging tree, then other patches
that are pending on the qapi events (such as Igor's proposal to add
ACPI_DEVICE_OST) will have something to rebase on.

requested? Thanks for the through review.

As mentioned in another thread, Wenchao was okay relaxing this to GPLv2+
- but do that as a followup rather than holding up this series.

Heh, I did the same wrong grep when writing the patch. :)
This is allocating a vector of _pointers_ to CharDriverState. The
pointers are initialized separately using create_eventfd_chr_device
(that uses qemu_chr_open_eventfd and hence qemu_chr_alloc).

The break is dead code; you could clean it up while in the area.

Wenchao, when you write your followup cleanups to this series, rewrite
this to use c_type(argentry, is_param=True) instead of pre-pending
"const " yourself (basically, take advantage of Amos' "qapi: add const
prefix to 'char *' insider c_type()" which is now in the tree ahead of
your patches).

Wenchao, as part of your followups to this series, I'd really like to
move qapi-event.json into qapi/event.json, so that all of our subset
.json files live in the same directory.

Latest QEMU is broken for w64. This command no longer starts the GTK gui:
wine64 x86_64-softmmu/qemu-system-x86_64 -L pc-bios
Wine reports a dead lock:
err:ntdll:RtlpWaitForCriticalSection section 0x964f0 "?" wait timed out
in thread 0009, blocked by 0000, retrying (60 sec)
git bisect finds this commit which introduced that regression:

qemu-char: make writes thread-safe
This will let threads other than the I/O thread raise QMP events.
GIOChannel is thread-safe, and send and receive state is usually
well-separated. The only driver that requires some care is the
pty driver, where some of the state is shared by the read and write
sides. That state is protected with the chr_write_lock too.

I did not run tests with 32 bit versions, nor did I run a native test on
Windows.

Actually this message is more likely to be a missing qemu_mutex_init,
and in fact that's what it is. I'm sorry, I'll send a patch right away.

This broke tests/qemu-iotests/040. Apparently, the BLOCK_JOB_READY
event changed from
{'timestamp': {'seconds': 1403791120, 'microseconds': 539716},
'data': {'device': 'drive0',
'type': 'commit',
'speed': 0,
'len': 1048576,
'offset': 1048576},
'event': 'BLOCK_JOB_READY'}
to just
{'timestamp': {'seconds': 1403790920, 'microseconds': 123232},
'data': {'device': 'drive0'},
'event': 'BLOCK_JOB_READY'}
breaking qemu-iotests/040's tests of data/type and data/len.
Documentation of BLOCK_JOB_READY shows only data/device, before and
after this patch.
Suggests that
* Before this patch, code disagreed with docs, and qemu-iotests/040
matched the code.
* After this patch, code matches docs, and qemu-iotests/040 matches
neither.
Please advise.

Agreed. We have to fix everything to match the code prior to the
conversion.
Are you going to take a stab at it yourself?

This broke tests/qemu-iotests/041. Apparently, the BLOCK_JOB_ERROR
event changed from
{'timestamp': {'seconds': 1403796871, 'microseconds': 446502},
'data': {'device': 'drive0',
'action': 'ignore',
'operation': 'write'},
'event': 'BLOCK_JOB_ERROR'}
to
{'timestamp': {'seconds': 1403796674, 'microseconds': 63271},
'data': {'device': '',
'action': 'report',
'operation': 'write'},
'event': 'BLOCK_JOB_ERROR'}
losing the value of device, which breaks qemu-iotests/041's tests of
data/device.
Please fix.

I suppose ignore vs. report is just from pasting two different sections?

The QAPI event series messed up two out of three event types tested in
qemu-iotests, if I count them correctly.
How can we gain confidence that we're not breaking half of the events
not tested there, too?

Let's fix 'em.

Let's test 'em. It would be superb to add tests for them.
I tested most of them myself before applying the series, but it was a
manual test. I didn't check/test every single field of every single event.

Will you post a patch, or would you like me to do that?

Nope, it's a genuine error in the patch. Working on a fix.
