The previous commit makes JSON strings containing '%' awkward to
express in templates: you'd have to mask the '%' with an Unicode
escape \u0025. No template currently contains such JSON strings.
Support the printf conversion specification %% in JSON strings as a
convenience anyway, because it's trivially easy to do.

The JSON parser optionally supports interpolation. This is used to
build QObjects by parsing string templates. The templates are C
literals, so parse errors (such as invalid interpolation
specifications) are actually programming errors. Consequently, the
functions providing parsing with interpolation
(qobject_from_jsonf_nofail(), qobject_from_vjsonf_nofail(),
qdict_from_jsonf_nofail(), qdict_from_vjsonf_nofail()) pass
&error_abort to the parser.
However, there's another, more dangerous kind of programming error:
since we use va_arg() to get the value to interpolate, behavior is
undefined when the variable argument isn't consistent with the
interpolation specification.
The same problem exists with printf()-like functions, and the solution
is to have the compiler check consistency. This is what
GCC_FMT_ATTR() is about.
To enable this type checking for interpolation as well, we carefully
chose our interpolation specifications to match printf conversion
specifications, and decorate functions parsing templates with
GCC_FMT_ATTR().
Note that this only protects against undefined behavior due to type
errors. It can't protect against use of invalid interpolation
specifications that happen to be valid printf conversion
specifications.
However, there's still a gaping hole in the type checking: GCC
recognizes '%' as start of printf conversion specification anywhere in
the template, but the parser recognizes it only outside JSON strings.
For instance, if someone were to pass a "{ '%s': %d }" template, GCC
would require a char * and an int argument, but the parser would
va_arg() only an int argument, resulting in undefined behavior.
Avoid undefined behavior by catching the programming error at run
time: have the parser recognize and reject '%' in JSON strings.

qobject_from_json() & friends use the consume_json() callback to
receive either a value or an error from the parser.
When they are fed a string that contains more than either one JSON
value or one JSON syntax error, consume_json() gets called multiple
times.
When the last call receives a value, qobject_from_json() returns that
value. Any other values are leaked.
When any call receives an error, qobject_from_json() sets the first
error received. Any other errors are thrown away.
When values follow errors, qobject_from_json() returns both a value
and sets an error. That's bad. Impact:
* block.c's parse_json_protocol() ignores and leaks the value. It's
used to to parse pseudo-filenames starting with "json:". The
pseudo-filenames can come from the user or from image meta-data such
as a QCOW2 image's backing file name.
* vl.c's parse_display_qapi() ignores and leaks the error. It's used
to parse the argument of command line option -display.
* vl.c's main() case QEMU_OPTION_blockdev ignores the error and leaves
it in @err. main() will then pass a pointer to a non-null Error *
to net_init_clients(), which is forbidden. It can lead to assertion
failure or other misbehavior.
* check-qjson.c's multiple_values() demonstrates the badness.
* The other callers are not affected since they only pass strings with
exactly one JSON value or, in the case of negative tests, one
error.
The impact on the _nofail() functions is relatively harmless. They
abort when any call receives an error. Else they return the last
value, and leak the others, if any.
Fix consume_json() as follows. On the first call, save value and
error as before. On subsequent calls, if any, don't save them. If
the first call saved a value, the next call, if any, replaces the
value by an "Expecting at most one JSON value" error. Take care not
to leak values or errors that aren't saved.

Both lexer and parser reject invalid interpolation specifications.
The parser's check is useless.
The lexer ends the token right after the first bad character. This
tends to lead to suboptimal error reporting. For instance, input
[ %04d ]
produces the tokens
JSON_LSQUARE [
JSON_ERROR %0
JSON_INTEGER 4
JSON_KEYWORD d
JSON_RSQUARE ]
The parser then yields an error, an object and two more errors:
error: Invalid JSON syntax
object: 4
error: JSON parse error, invalid keyword
error: JSON parse error, expecting value
Dumb down the lexer to accept [A-Za-z0-9]*. The parser's check is now
used. Emit a proper error there.

The callback to consume JSON values takes QObject *json, Error *err.
If both are null, the callback is supposed to make up an error by
itself. This sucks.
qjson.c's consume_json() neglects to do so, which makes
qobject_from_json() null instead of failing. I consider that a bug.
The culprit is json_message_process_token(): it passes two null
pointers when it runs into a lexical error or a limit violation. Fix
it to pass a proper Error object then. Update the callbacks:
* monitor.c's handle_qmp_command(): the code to make up an error is
now dead, drop it.
* qga/main.c's process_event(): lumps the "both null" case together
with the "not a JSON object" case. The former is now gone. The
error message "Invalid JSON syntax" is misleading for the latter.
Improve it to "Input must be a JSON object".
* qobject/qjson.c's consume_json(): no update; check-qjson
demonstrates qobject_from_json() now sets an error on lexical
errors, but still doesn't on some other errors.

The classical way to structure parser and lexer is to have the client
call the parser to get an abstract syntax tree, the parser call the
lexer to get the next token, and the lexer call some function to get
input characters.
Another way to structure them would be to have the client feed
characters to the lexer, the lexer feed tokens to the parser, and the
parser feed abstract syntax trees to some callback provided by the
client. This way is more easily integrated into an event loop that
dispatches input characters as they arrive.
Our JSON parser is kind of between the two. The lexer feeds tokens to
a "streamer" instead of a real parser. The streamer accumulates
tokens until it got the sequence of tokens that comprise a single JSON
value (it counts curly braces and square brackets to decide). It
feeds those token sequences to a callback provided by the client. The
callback passes each token sequence to the parser, and gets back an
abstract syntax tree.
I figure it was done that way to make a straightforward recursive
descent parser possible. "Get next token" becomes "pop the first
token off the token sequence". Drawback: we need to store a complete
token sequence. Each token eats 13 + input characters + malloc
overhead bytes.
Observations:
1. This is not the only way to use recursive descent. If we replaced
"get next token" by a coroutine yield, we could do without a
streamer.
2. The lexer reports errors by passing a JSON_ERROR token to the
streamer. This communicates the offending input characters and
their location, but no more.
3. The streamer reports errors by passing a null token sequence to the
callback. The (already poor) lexical error information is thrown
away.
4. Having the callback receive a token sequence duplicates the code to
convert token sequence to abstract syntax tree in every callback.
5. Known bug: the streamer silently drops incomplete token sequences.
This commit rectifies 4. by lifting the call of the parser from the
callbacks into the streamer. Later commits will address 3. and 5.
The lifting removes a bug from qjson.c's parse_json(): it passed a
pointer to a non-null Error * in certain cases, as demonstrated by
check-qjson.c.
json_parser_parse() is now unused. It's a stupid wrapper around
json_parser_parse_err(). Drop it, and rename json_parser_parse_err()
to json_parser_parse().

The VM tests currently have a timeout of 2 minutes for trying
to connect to ssh. Since the guest VM has to boot from cold
to the point of accepting inbound ssh during this time, if the
host machine is heavily loaded it can spuriously time out.

Certain device introspection crashes used to only happen if you were
using a certain machine, e.g. if the machine was using serial_hd() or
nd_table[], and a device was trying to use these in its instance_init
function, too.
To be able to catch these problems, let's extend the device-introspect
test to check the devices on all machine types, with and without the
"-nodefaults" parameter (since this makes a difference sometimes, too).
Since this is a rather slow operation, and most of the problems are
already handled by testing with the "none" machine only, the test with
all machines is only run in the "make check SPEED=slow" mode.

The tests that check something for all machine types currently spend
a lot of time checking old machine types (like "pc-i440fx-2.0" for
example). The chances that we find something new there in addition
to checking the latest version of a machine type are pretty low, so
we should not waste the time of the developers by testing this again
and again in the "quick" testing mode.
Thus let's add some code to determine whether we are testing a current
machine type or an old one, and only test the old types if we are
running in "SPEED=slow" mode.
This decreases the testing time quite a bit now, e.g. the qom-test
now finishes within 4 seconds for qemu-system-x86_64 instead of 30
seconds when testing all machines.

Because qtest does not support s390 channel I/O, s390 only performs smoke tests on
those few devices that do not have any functional tests. Therefore, every time we
add functional tests for a virtio device, the choice is between removing
those tests from the s390 suite (so that s390 actually _loses_ coverage)
or sprinkling the test with architecture checks.
This patch simply creates a ccw-specific test that only performs smoke tests on
all virtio-ccw devices. If channel I/O support is ever added to qtest and libqos,
then this file can go away. In the meanwhile, it simplifies maintenance and
makes sure that all virtio devices are tested.

When read() from the qtest socket or the QMP socket fails or EOFs, we
report "Broken pipe" and exit(1). This commonly happens when QEMU
crashes. It also happens when QEMU refuses to run because the test
passed it bad arguments. Sadly, we neglect to report either.
Improve this by calling abort() instead of exit(1), so kill_qemu()
runs, and reports how QEMU died. This improves error reporting to
something like
/x86_64/device/introspect/list: Broken pipe
tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 6 (Aborted) (dumped core)
Three exit() remain in libqtest.c:
* In qmp_response(), when we can't parse a QMP reply read from the QMP
socket. Change to abort() for consistency.
* In qtest_qemu_binary(), when QTEST_QEMU_BINARY isn't in the
environment. This can only happen before we start QEMU. Leave
alone.
* In qtest_init_without_qmp_handshake(), when the fork()ed child fails
to execlp(). Leave alone.
exit() elsewhere are unlikely due to QEMU dying on us. If that should
turn out to be wrong, we can move kill_qemu() from @abrt_hooks to
atexit() or something.

[Commit message tweaked slightly]
In kill_qemu() we have an assert that checks that the QEMU process
didn't dump core:
assert(!WCOREDUMP(wstatus));
Unfortunately the WCOREDUMP macro here means the resulting message
is not very easy to comprehend on at least some systems:
ahci-test: tests/libqtest.c:113: kill_qemu: Assertion `!(((__extension__ (((union { __typeof(wstatus) __in; int __i; }) { .__in = (wstatus) }).__i))) & 0x80)' failed.
and it doesn't identify what signal the process took. What's more,
WCOREDUMP is not reliable - in some cases, setrlimit() coupled with
kernel dump settings can result in the flag not being set. It's
better to log ALL death by signal, instead of caring whether a core
dump was attempted (although once we know a signal happened, also
mentioning if a core dump is present can be helpful).
Furthermore, we are NOT detecting EINTR (while EINTR shouldn't be
happening if we didn't install signal handlers, it's still better
to always be robust).
Finally, even non-signal death with a non-zero status is suspicious,
since qemu's SIGINT handler is supposed to result in exit(0).
Instead of using a raw assert, print the information in an
easier to understand way:
/i386/ahci/sanity: tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 11 (Segmentation fault) (core dumped)
(Of course, the really useful information would be why the QEMU
process dumped core in the first place, but we don't have that
by the time the test program has picked up the exit status.)

Leaving interpolation into JSON to qmp() is more robust than building
QMP input manually, as explained in the commit before previous.
qtest_qmp_device_add() and its wrappers interpolate into JSON as
follows:
* qtest_qmp_device_add() interpolates members into a JSON object.
* So do its wrappers qpci_plug_device_test() and usb_test_hotplug().
* usb_test_hotplug() additionally interpolates strings and numbers
into JSON strings.
Clean them up:
* Have qtest_qmp_device_add() take its extra device properties as
arguments for qdict_from_jsonf_nofail() instead of a string
containing JSON members.
* Drop qpci_plug_device_test(), use qtest_qmp_device_add()
directly.
* Change usb_test_hotplug() parameter @port to string, to avoid
interpolation. Interpolate @hcd_id separately.

test_plug_with_device_add_x86() plugs Haswell-i386-cpu and
Haswell-x86_64-cpu with device_add. It passes socket-id, core-id,
thread-id as JSON strings. The properties are actually integers.
test_plug_with_device_add_coreid() plugs power8_v2.0-spapr-cpu-core

The properties are actually integers.
Passing JSON string values to integer properties works only due to

numbers. While there, use %u rather than %i with unsigned int.

When you build QMP input manually like this
cmd = g_strdup_printf("{ 'execute': 'migrate',"
"'arguments': { 'uri': '%s' } }",
uri);
rsp = qmp(cmd);
g_free(cmd);
you're responsible for escaping the interpolated values for JSON. Not
done here, and therefore works only for sufficiently nice @uri. For
instance, if @uri contained a single "'", qobject_from_vjsonf_nofail()
would abort. A sufficiently nasty @uri could even inject unwanted
members into the arguments object.
Leaving interpolation into JSON to qmp() is more robust:
rsp = qmp("{ 'execute': 'migrate', 'arguments': { 'uri': %s } }", uri);
It's also more concise.
Clean up the simple cases where we interpolate exactly a JSON value.

Commit ab45015a96 "qobject: Let qobject_from_jsonf() fail instead of
abort" fails to accomplish its stated aim: the function can still
abort due to its use of &error_abort.
Its rationale for letting it fail is that all remaining users cope
fine with failure. Well, they're just fine with aborting, too; it's
what they do on failure.
Simply reverting the broken commit would bring back the unfortunate
asymmetry between qobject_from_jsonf() and qobject_from_jsonv(): one
aborts, the other returns null. So also rename it to
qobject_from_jsonf_nofail().

that this is an active commit. When adding the intermediate nodes with

the backing file of source, though, so it never reaches target and
instead runs into NULL at the base.
While we could fix that by starting with source itself, there is no

A throttle group can have several members, and each one of them can
have several pending requests in the queue.
The requests are processed in a round-robin fashion, so the algorithm
decides the drive that is going to run the next request and sets a
timer in it. Once the timer fires and the throttled request is run
then the next drive from the group is selected and a new timer is set.
If the user tried to remove a drive from a group and that drive had a
timer set then the code was not taking care of setting up a new timer
in one of the remaining members of the group, freezing their I/O.

Unfortunately this change has global impact across the entire test suite
and means that when tests fail for unexpected reasons, the message is
not displayed on stderr. eg when using &error_abort in a call the test
merely prints
Unexpected error in qcrypto_tls_session_check_certificate() at crypto/tlssession.c:280:
and the actual error message is hidden, making it impossible to diagnose
the failure. This is especially problematic in CI or build systems where
it isn't possible to easily pass the --debug-log flag to tests and
re-run with the test log visible.
This change makes the previous big hammer much more nuanced, providing a
flag in the stub error_vprintf() that can used on a per-test basis to
silence the errors. Only the test-vmstate silences errors initially.

Setting up binfmt_misc is outside of the scope of the docker.py script
but we can at least validate it with any given executable so we have a
more useful error message than the sed line of deboostrap failing
cryptically.

We do a minimum version check for the debootstrap but if the distro
has added their own minor version tick it would fail and fall-back to
the SCM version. This is sub-optimal as the latest/greatest version
may be broken at any one particular time. We fix that with a little
sed magic on the version string before passing to our ugly shell
versioning check.

This is just a note that later versions of debootstrap don't
technically need this hack.

When a check fails we currently just report why we failed. This is not
totally helpful to people who want to boot-strap a new image. Report a
hint as to why it failed.

The addition of QEMU_TARGET was intended to ensure we fall back to
checking for the existence of an image if the build system was not
currently configured to build it. However this breaks the direct use
of the rule for building custom binfmt_misc images. We already check
for EXECUTABLE so let us just use that as a proxy for deciding if we
are just going to check the image exits.

This allows us to run a particular test on all docker images. For
example:
make docker-test-unit
Will run the unit tests on every supported image. At the same time
rename docker-test to docker-all-tests to be clearer.

This test doesn't even build QEMU, it just builds and runs all the
unit tests. Intended to make checking unit tests on all docker images
easier.

Rename DOCKER_INTERMEDIATE_IMAGES to DOCKER_PARTIAL_IMAGES and add the
incomplete cross compiler images that can build tests but can't build
QEMU itself. We also add debian, debian-bootstrap and the tricode
images to the list.
