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.
* tests/libqtest.c's qmp_response(): the Error object is now reliable,
so use it to improve the error message.

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().

json_parser_parse_err() may return something else than a QDict, in
which case we loose the object. Let's keep track of the original
object to avoid leaks.
When an error occurs, "qdict" contains the response, but we still
check the "execute" key there. Untangle a bit this code, by having a

bios_support_mode verifies if the guest has support for a certain
suspend mode but it doesn't inform back which suspend tool
provides it. The caller, guest_suspend, executes all suspend
strategies in order again.
After adding systemd suspend support, bios_support_mode now will
verify for support for systemd, then pmutils, then Linux sys state
file. In a worst case scenario where both systemd and pmutils isn't
supported but Linux sys state is:
- bios_supports_mode will check for systemd, then pmutils, then
Linux sys state. It will tell guest_suspend that there is support,
but it will not tell who provides it;
- guest_suspend will try to execute (and fail) systemd suspend,
then pmutils suspend, to only then use the Linux sys suspend.
The time spent executing systemd and pmutils suspend was wasted
and could be avoided, but only bios_support_mode knew it but
didn't inform it back.
A quicker approach is to nuke bios_supports_mode and control
whether we found support at all with a bool flag inside
guest_suspend. guest_suspend will search for suspend support
and execute it as soon as possible. If the a given suspend
mechanism fails, continue to the next. If no suspend
support is found, the "not supported" message is still being
sent back to the user.

pmutils isn't being supported by newer OSes like Fedora 27
or Mint. This means that the only suspend option QGA offers
for these guests are writing directly into the Linux sys state
file. This also means that QGA also loses the ability to do
hybrid suspend in those guests - this suspend mode is only
available when using pmutils.
Newer guests can use systemd facilities to do all the suspend
types QGA supports. The mapping in comparison with pmutils is:
- pm-hibernate -> systemctl hibernate
- pm-suspend -> systemctl suspend
- pm-suspend-hybrid -> systemctl hybrid-sleep
To discover whether systemd supports these functions, we inspect
the status of the services that implements them.
With this patch, we can offer hybrid suspend again for newer
guests that do not have pmutils support anymore.

This is a cleanup of the resulting code after detaching
pmutils and Linux sys state file logic:
- remove the SUSPEND_MODE_* macros and use an enumeration
instead. At the same time, drop the switch statements
at the start of each function and use the enumeration
index to get the right binary/argument;
- create a new function called run_process_child(). This
function uses g_spawn_sync() to execute a shell command,
returning the exit code. This is a common operation in the
pmutils functions and will be used in the systemd implementation
as well, so this function will avoid code repetition.
There are more places inside commands-posix.c where this new
run_process_child function can also be used, but one step

In bios_supports_mode there is a verification to assert if

if not, we see if the Linux sys state files supports it.
This verification is done in the same function, one after
the other, and it works for now. But, when adding a new
suspend mechanism that will not necessarily follow the same
return 0 or 1 logic of pmutils, this code will be hard
to deal with.
This patch decouple the two existing logics into their own

which in turn are used inside bios_support_mode. The existing

Per supported platforms doc[1], the various min glib on relevant distros is:
RHEL-7: 2.50.3
Debian (Stretch): 2.50.3
Debian (Jessie): 2.42.1
OpenBSD (Ports): 2.54.3
FreeBSD (Ports): 2.50.3
OpenSUSE Leap 15: 2.54.3
SLE12-SP2: 2.48.2
Ubuntu (Xenial): 2.48.0
macOS (Homebrew): 2.56.0
This suggests that a minimum glib of 2.42 is a reasonable target.
The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only
has glib 2.40.0, and this is needed for testing during merge. Thus an
exception is made to the documented platform support policy to allow for
all three current LTS releases to be supported.

The same confusion exists with the "query-version" QMP command.

Note that this also changes the behavior of the "query-version" QMP

At the moment, Windows libraries don't provide a way to access
RTC, so, a workaround is to use the Windows w32tm command to
resync the time.

When VM is in a heavy IO, if the command "guest-fsfreeze-freeze"
is executed, VSS may timeout when trying to hold writes.
Inside guest, Event ID 12298(VSS_ERROR_HOLD_WRITES_TIMEOUT)
is logged in the Event Viewer.
At that time, if we call AbortBackup, qga may hang forever.
This patch will solve this issue.

Convert all the single line uses of fprintf(stderr, "warning:"..."\n"...
to use warn_report() instead. This helps standardise on a single
method of printing warnings to the user.
All of the warnings were changed using this command:
find ./* -type f -exec sed -i \
's|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig' \
{} +
Some of the lines were manually edited to reduce the line length to below
80 charecters.
The #include lines were manually updated to allow the code to compile.

These days, many programs are including a bug-reporting address,
or better yet, a link to the project web site, at the tail of
their --help output. However, we were not very consistent at
doing so: only qemu-nbd and qemu-qa mentioned anything, with the
latter pointing to an individual person instead of the project.
Add a new #define that sets up a uniform string, mentioning both
bug reporting instructions and overall project details, and which
a downstream vendor could tweak if they want bugs to go to a
downstream database. Then use it in all of our binaries which
have --help output.
The canned text intentionally references http:// instead of https://
because our https website currently causes certificate errors in
some browsers. That can be tweaked later once we have resolved the
web site issued.
