These cases require a bit more thought to review; in each case, the

The easiest spots to use QAPI_LIST_APPEND are where we already have an
obvious pointer to the tail of a list. While at it, consistently use
the variable name 'tail' for that purpose.

Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND(). But places where we must keep the list in order
by appending remain open-coded until later patches.
Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

Add API and stubs for new guest-get-disks command.
The command guest-get-fsinfo can be used to list information about disks
and partitions but it is limited only to mounted disks with filesystem.
This new command should allow listing information about disks of the VM
regardles whether they are mounted or not. This can be usefull for
management applications for mapping virtualized devices or pass-through
devices to device names in the guest OS.

Simple unions are simpler than flat unions in the schema, but more
complicated in C and on the QMP wire: there's extra indirection in C

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
qmp_guest_get_devices() is wrong that way: it calls error_setg() in a
loop.
If no iteration fails, the function returns a value and sets no error.
Okay.
If exactly one iteration fails, the function returns a value and sets
an error. Wrong.
If multiple iterations fail, the function trips error_setv()'s
assertion.
Fix it to return immediately on error.
Perhaps the failure to convert the driver version to UTF-8 should not
be an error. We could simply not report the botched version string
instead.

Add command for reporting devices on Windows guest. The intent is not so
much to report the devices but more importantly the driver (and its
version) that is assigned to the device. This gives caller the
information whether VirtIO drivers are installed and/or whether
inadequate driver is used on a device (e.g. QXL device with base VGA
driver).
Example:
[

When all we do with an Error we receive into a local variable is

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {
goto out
}
...
out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().
Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.
The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().
Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there. Converted manually.
Line breaks tidied up manually. One nested declaration of @local_err
deleted manually. Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

Replace
error_setg(&err, ...);
error_propagate(errp, err);
by
error_setg(errp, ...);
Related pattern:
if (...) {
error_setg(&err, ...);
goto out;
}
...
out:
error_propagate(errp, err);
return;
When all paths to label out are that way, replace by
if (...) {
error_setg(errp, ...);
return;
}
and delete the label along with the error_propagate().
When we have at most one other path that actually needs to propagate,
and maybe one at the end that where propagation is unnecessary, e.g.
foo(..., &err);
if (err) {
goto out;
}
...
bar(..., &err);
out:
error_propagate(errp, err);
return;
move the error_propagate() to where it's needed, like
if (...) {
foo(..., &err);
error_propagate(errp, err);
return;
}
...
bar(..., errp);
return;
and transform the error_setg() as above.
In some places, the transformation results in obviously unnecessary
error_propagate(). The next few commits will eliminate them.
Bonus: the elimination of gotos will make later patches in this series
easier to review.
Candidates for conversion tracked down with this Coccinelle script:

As noted by Daniel Berrangé in [*], the fix from commit 807e2b6fce
which replaced malloc() by try_malloc() is not enough, the process
can still run out of memory a few line later:
346 buf = g_try_malloc0(count + 1);
347 if (!buf) {
348 error_setg(errp,
349 "failed to allocate sufficient memory "
350 "to complete the requested service");
351 return NULL;
352 }
353 is_ok = ReadFile(fh, buf, count, &read_count, NULL);
354 if (!is_ok) {
355 error_setg_win32(errp, GetLastError(), "failed to read file");
356 slog("guest-file-read failed, handle %" PRId64, handle);
357 } else {
358 buf[read_count] = 0;
359 read_data = g_new0(GuestFileRead, 1);
^^^^^^
Instead we are going to put a low hard limit on 'count' in the next
commits. This reverts commit 807e2b6fce022707418bc8f61c069d91c613b3d2.

guest-file-read command is currently implemented to read from a
file handle count number of bytes. when executed with a very large count number
qemu-ga crashes.
after some digging turns out that qemu-ga crashes after trying to allocate
a buffer large enough to save the data read in it, the buffer was allocated using
g_malloc0 which is not fail safe, and results a crash in case of failure.
g_malloc0 was replaced with g_try_malloc0() which returns NULL on failure,
A check was added for that case in order to prevent qemu-ga from crashing
and to send a response to the qemu-ga client accordingly.

Network interface name is fetched as an encoded WCHAR array, (wide
character), then it is decoded using the guest's CP_ACP Windows code
page, which is the default code page as configure in the guest's
Windows, then it is returned as a byte array, (char array).
As stated in the BZ#1733165, when renaming a network interface to a
Chinese name and invoking this command, the returned name field has
the (\ufffd) value for each Chinese character the name had, this
value is an indication that the code page does not have the decoding
information for the given character.
This bug is a result of using the CP_ACP code page for decoding which
is an interchangeable code page, instead CP_UTF8 code page should be
used for decoding the network interface's name.

Since Windows Server 2016, Microsoft stopped upgrading the major and minor
versions of their new Windows Server product, so, the current functionality
of checking major and minor version numbers to determine the Windows Server
version wont work as expected.
The implemented solution here is to use the build number in addition to the
major and minor version numbers of the product to determine the Windows
Server product version.
The final build number of Windows Server 2016 is 14939, and
the final build number of Windows Server 2019 is 17764, so any Windows
Server product that has the major version of 10 and minor version of 0
with a build number lower or equal to 14939 will resemble 2016 and if the
build number is lower or equal to 17763 will resemble 2019.

The call to SetupDiGetDeviceRegistryProperty might fail because the
value doesn't exist in the registry, in this case we shouldn't exit from
the loop but instead continue to look for other available values in the
registry and set this value as unavailable (-1).

The fsinfo command is currently implemented for Windows only and it's disk
parameter can be enabled by adding the define "CONFIG_QGA_NTDDSCSI" to the qga
code. When enabled and executed the qemu-ga crashed with the following message:
------------------------------------------------
File qapi/qapi-visit-core.c, Line 49
Expression: !(v->type & VISITOR_OUTPUT) || *obj)
------------------------------------------------
After some digging, turns out that the GuestPCIAddress is null and the
qapi visitor doesn't like that, so we can always allocate it instead and
initiate all it's members to -1.

Currently, the win32 port of QEMU Guest Agent does not properly handle Unicode
paths. The JSON decoder produces a valid UTF-8 path string, but this is passed
directly to CreateFileA, which is expecting an ANSI string and not UTF-8. This
leads to mangled filenames.
This patch follows the example of qmp_guest_set_user_password() and uses
g_utf8_to_utf16() to convert the string to UTF-16 and calls CreateFileW()
explicitly.

The defrag.exe tool which is used for executing the fstrim command
on Windows doesn't support retrim for OSes lower than Win8. This
commit handles this case and returns a suitable error.

While reading file content via 'guest-file-read' command,
'qmp_guest_file_read' routine allocates buffer of count+1
bytes. It could overflow for large values of 'count'.
Add check to avoid it.

Move qapi-schema.json to qapi/, so it's next to its modules, and all
files get generated to qapi/, not just the ones generated for modules.
Consistently name the generated files qapi-MODULE.EXT:
qmp-commands.[ch] become qapi-commands.[ch], qapi-event.[ch] become
qapi-events.[ch], and qmp-introspect.[ch] become qapi-introspect.[ch].
This gets rid of the temporary hacks in scripts/qapi/commands.py,
scripts/qapi/events.py, and scripts/qapi/common.py.
