The string input visitor tries to cope with null input. Null input
isn't used anywhere, and isn't covered by tests. Unsurprisingly, it
doesn't fully work: start_list() crashes because it passes the input
via parse_str() to strtoll() unchecked.
Make string_input_visitor_new() assert its argument isn't null, and
drop the code trying to deal with null input.
The opts visitor crashes when you try to actually visit something with
null input. Make opts_visitor_new() assert its argument isn't null,
mostly for clarity.
qobject_input_visitor_new() already asserts its argument isn't null.

visit_optional() is to be called only between visit_start_struct() and
visit_end_struct(). Visitors that don't support struct visits,
i.e. don't implement start_struct(), end_struct(), have no use for it.

Error messages refer to nodes of the QObject being visited by name.
Trouble is the names are sometimes less than helpful:
* The name of the root QObject is whatever @name argument got passed
to the visitor, except NULL gets mapped to "null". We commonly pass
NULL. Not good.
Avoiding errors "at the root" mitigates. For instance,
visit_start_struct() can only fail when the visited object is not a
dictionary, and we commonly ensure it is beforehand.
* The name of a QDict's member is the member key. Good enough only
when this happens to be unique.
* The name of a QList's member is "null". Not good.
Improve error messages by referring to nodes by path instead, as
follows:
* The path of the root QObject is whatever @name argument got passed
to the visitor, except NULL gets mapped to "<anonymous>".
* The path of a root QDict's member is the member key.
* The path of a root QList's member is "[%u]", where %u is the list
index, starting at zero.
* The path of a non-root QDict's member is the path of the QDict
concatenated with "." and the member key.
* The path of a non-root QList's member is the path of the QList
concatenated with "[%u]", where %u is the list index.
For example, the incorrect QMP command
{ "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "raw", "file": {"driver": "file" } } }
now fails with
{"error": {"class": "GenericError", "desc": "Parameter 'file.filename' is missing"}}
instead of
{"error": {"class": "GenericError", "desc": "Parameter 'filename' is missing"}}
and
{ "execute": "input-send-event", "arguments": { "device": "bar", "events": [ [] ] } }
now fails with
{"error": {"class": "GenericError", "desc": "Invalid parameter type for 'events[0]', expected: object"}}
instead of
{"error": {"class": "GenericError", "desc": "Invalid parameter type for 'null', expected: QDict"}}
Aside: calling the thing "parameter" is suboptimal for QMP, because
the root object is "arguments" there.
The qobject output visitor doesn't have this problem because it should
not fail. Same for dealloc and clone visitors.
The string visitors don't have this problem because they visit just
one value, whose name needs to be passed to the visitor as @name. The
string output visitor shouldn't fail anyway.
The options visitor uses QemuOpts names. Their name space is flat, so
the use of QDict member keys as names is fine. NULL names used with
roots and lists could conceivably result in bad error messages. Left
for another day.

The QObject input visitor has three error message formats:
* Parameter '%s' is missing
* "Invalid parameter type for '%s', expected: %s"
* "QMP input object member '%s' is unexpected"
The '%s' are member names (or "null", but I'll fix that later).
The last error message calls the thing "QMP input object member"
instead of "parameter". Misleading when the visitor is used on
QObjects that don't come from QMP. Change it to "Parameter '%s' is

qmp_check_input_obj() duplicates qmp_dispatch_check_obj(), except the
latter screws up an error message. handle_qmp_command() runs first
the former, then the latter via qmp_dispatch(), masking the screwup.
qemu-ga also masks the screwup, because it also duplicates checks,
just differently.
qmp_check_input_obj() exists because handle_qmp_command() needs to
examine the command before dispatching it. The previous commit got
rid of this need, except for a tracepoint, and a bit of "id" code that
relies on qdict not being null.
Fix up the error message in qmp_dispatch_check_obj(), drop

The value of key 'arguments' must be a JSON object. qemu-ga neglects
to check, and crashes. To reproduce, send
{ 'execute': 'guest-sync', 'arguments': [] }
to qemu-ga.
do_qmp_dispatch() uses qdict_get_qdict() to get the arguments. When
not a JSON object, this gets a null pointer, which flows through the
generated marshalling function to qobject_input_visitor_new(), where
it fails the assertion. qmp_dispatch_check_obj() needs to catch this
error.
QEMU isn't affected, because it runs qmp_check_input_obj() first,
which basically duplicates qmp_dispatch_check_obj()'s checks, plus the
missing one.
Fix by copying the missing one from qmp_check_input_obj() to
qmp_dispatch_check_obj().

We intentionally renamed 'debug-level' to 'debug' in the QMP
schema for 'blockdev-add' related to gluster, in order to
match the command line (commit 1a417e46). However, since
'debug-level' was visible in 2.7, that means that we should
document that 'debug' was not available until 2.8.
The change was intentional because 'blockdev-add' itself
underwent incompatible changes (such as commit 0153d2f) for
the same release; our intent is that after 2.8, these
interfaces will now be stable. [In hindsight, we should have

The qobject_from_jsonf() function implements a pseudo-printf
language for creating a QObject; however, it is hard-coded to
only parse a subset of formats understood by -Wformat, and is
not a straight synonym to bare printf(). In particular, any
use of an int64_t integer works only if the system's
definition of PRId64 matches what the parser expects; which
works on glibc (%lld or %ld depending on 32- vs. 64-bit) and
mingw (%I64d), but not on Mac OS (%qd). Rather than enhance
the parser, it is just as easy to use 'long long', which we
know always works. There are few enough callers of
qobject_from_json[fv]() that it is easy to audit that this is
the only non-testsuite caller that was actually relying on
this particular conversion.

[Cast tv.tv_sec, tv.tv_usec to long long for type correctness]
Signed-off-by: Markus Armbruster <armbru@redhat.com>
Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.
Therefore, it should be safe to just drop it from curl's protocol list.
[Jeff Cody: Below is additional summary pulled, with some rewording,
from followup emails between Max and Markus, to explain what
worked and what didn't]
TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero. By default,
that readahead size is 256KB.
Reads starting at a non-zero offset would also have returned data from a
zero offset. It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.
In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.

The event currently only contains the BlockBackend name. However, with
anonymous BlockBackends, this is always the empty string. Add the qdev
ID (or if none was given, the QOM path) so that the user can still see
which device caused the event.
Event generation has to be moved from bdrv_eject() to the BlockBackend
because the BDS doesn't know the attached device, but that's easy
because blk_eject() is the only user of it.

The option whether or not to use a native AIO interface really isn't a
generic option for all drivers, but only applies to the native file
protocols. This patch moves the option in blockdev-add to the
appropriate places (raw-posix and raw-win32).
We still have to keep the flag BDRV_O_NATIVE_AIO for compatibility
because so far the AIO option was usually specified on the wrong layer
(the top-level format driver, which didn't even look at it) and then
inherited by the protocol driver (where it was actually used). We can't
forbid this use except in new interfaces.
