the current implementation fails if we try to freeze an
already frozen filesystem. This can happen if a filesystem
is mounted more than once (e.g. with a bind mount).

AF_UNIX and AF_VSOCK listen sockets can be passed in by systemd on
startup. This allows systemd to manage the listen socket until the
first client connects and between restarts. Advantages of socket
activation are that parallel startup of network services becomes
possible and that unused daemons do not consume memory.
The key to achieving this is the LISTEN_FDS environment variable, which
is a stable ABI as shown here:
https://www.freedesktop.org/wiki/Software/systemd/InterfacePortabilityAndStabilityChart/
We could link against libsystemd and use sd_listen_fds(3) but it's easy
to implement the tiny LISTEN_FDS ABI so that qemu-ga does not depend on
libsystemd. Some systems may not have systemd installed and wish to
avoid the dependency. Other init systems or socket activation servers
may implement the same ABI without systemd involvement.
Test as follows:
$ cat ~/.config/systemd/user/qga.service
[Unit]
Description=qga
[Service]
WorkingDirectory=/tmp
ExecStart=/path/to/qemu-ga --logfile=/tmp/qga.log --pidfile=/tmp/qga.pid --statedir=/tmp

The way we get QMP commands registered is high tech:
* qapi-commands.py generates qmp_init_marshal() that does the actual work
* it also generates the magic to register it as a MODULE_INIT_QAPI
function, so it runs when someone calls
module_call_init(MODULE_INIT_QAPI)
* main() calls module_call_init()
QEMU needs to register a few non-qapified commands. Same high tech
works: monitor.c has its own qmp_init_marshal() along with the magic
to make it run in module_call_init(MODULE_INIT_QAPI).
QEMU also needs to unregister commands that are not wanted in this
build's configuration (commit 5032a16). Simple enough:
qmp_unregister_commands_hack(). The difficulty is to make it run
after the generated qmp_init_marshal(). We can't simply run it in
monitor.c's qmp_init_marshal(), because the order in which the
registered functions run is indeterminate. So qmp_init_marshal()
registers qmp_unregister_commands_hack() separately. Since
registering *appends* to the list of registered functions, this will
make it run after all the functions that have been registered already.
I suspect it takes a long and expensive computer science education to
not find this silly.
Dumb it down as follows:
* Drop MODULE_INIT_QAPI entirely
* Give the generated qmp_init_marshal() external linkage.
* Call it instead of module_call_init(MODULE_INIT_QAPI)
* Except in QEMU proper, call new monitor_init_qmp_commands() that in
turn calls the generated qmp_init_marshal(), registers the
additional commands and unregisters the unwanted ones.

Explicit GA_CHANNEL_UNIX_LISTEN checks are not necessary since serial
channel types do not create the listen channel (c->listen_channel).

The quiet-command make rule currently takes two arguments:
the command and arguments to run, and a string to print if
the V flag is not set (ie we are not being verbose).
By convention, the string printed is of the form
" NAME some args". Unfortunately to get nicely lined up
output all the strings have to agree about what column the
arguments should start in, which means that if we add a
new quiet-command usage which wants a slightly longer CMD
name then we either put up with misalignment or change
every quiet-command string.
Split the quiet-mode string into two, the "NAME" and
the "same args" part, and use printf(1) to format the
string automatically. This means we only need to change
one place if we want to support a longer maximum name.
In particular, we can now print 7-character names lined
up properly (they are needed for the OSX "SETTOOL" invocation).
Change all the uses of quiet-command to the new syntax.
(Any which are missed or inadvertently reintroduced
via later merges will result in slightly misformatted
quiet output rather than disaster.)
A few places in the pc-bios/ makefiles are updated to use
"BUILD", "SIGN" and "STRIP" rather than "Building",
"Signing" and "Stripping" for consistency and to keep them
below 7 characters. Module .mo links now print "LD" rather
than the nonstandard "LD -r".

mingw-glib uses helper process to assist gspawn() api. There are two
versions of helpers, one with main() and another with WinMain() startup
routines.
Whenever gspawn() detects consoleless environment (and qemu-ga is running
in such environment as Win32 service), it chooses helper with main()
instead of WinMain. It is done by name, e.g.
gspawn-win32-helper-console.exe vs gspawn-win32-helper.exe
Running console-aware application like any win32 console apps from main()
crt initalized process results in redirection of stdout to console created
in crt startup instead of parent-provided handle connected to subprocess
pipe. Thus, stdout/stderr redirection do not work correctly.
The patch makes WinMain()'s version of helper be used as the only helper
shipped with qemu-ga package. Using only win32 helper ensures console
is created before any redirection and fixes stdout/stderr redirection
issue.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

Exposing OS-specific SEEK_ constants in our qapi was a mistake
(if the host has SEEK_CUR as 1, but the guest has it as 2, then
the semantics are unclear what should happen); if we had a time
machine, we would instead expose only a symbolic enum. It's too
late to change the fact that we have an integer in qapi, but we
can at least document what mapping we want to enforce for all
qga clients (and luckily, it happens to be the mapping that both
Linux and Windows use); then fix the code to match that mapping.
It also helps us filter out unsupported SEEK_DATA and SEEK_HOLE.
In the future, we may wish to move our QGA_SEEK_* constants into
qga/qapi-schema.json, along with updating the schema to take an
alternate type (either the integer, or the string value of the
enum name) - but that's too much risk during hard freeze.

The patch introduces qemu_set_handle_nonoblocking, the local analog

The usage of handles in qemu_set_non/block is impossible, because for
win32 there is a difference between file discriptors and file handles,

Two, it returns T * rather than void *, which lets the compiler catch

This is particularly useful when we abort in error_propagate(),
because there the stack backtrace doesn't lead to where the error was
created. Looks like this:
Unexpected error in parse_block_error_action() at .../qemu/blockdev.c:322:
qemu-system-x86_64: -drive if=none,werror=foo: 'foo' invalid write error action
Aborted (core dumped)
Note: to get this example output, I monkey-patched drive_new() to pass
&error_abort to blockdev_init().
To keep the error handling boiler plate from growing even more, all
error_setFOO() become macros expanding into error_setFOO_internal()
with additional __FILE__, __LINE__, __func__ arguments. Not exactly
pretty, but it works.
The macro trickery breaks down when you take the address of an
error_setFOO(). Fortunately, we do that in just one place: qemu-ga's
Windows VSS provider and requester DLL wants to call
error_setg_win32() through a function pointer "to avoid linking glib
to the DLL". Use error_setg_win32_internal() there. The use of the
function pointer is already wrapped in a macro, so the churn isn't
bad.
Code size increases by some 35KiB for me (0.7%). Tolerable. Could be
less if we passed relative rather than absolute source file names to
the compiler, or forwent reporting __func__.

requester.cpp uses this pattern to receive an error and pass it on to
the caller (err_is_set() macro peeled off for clarity):
... code that may set errset->errp ...
if (errset->errp && *errset->errp) {
... handle error ...
}
This breaks when errset->errp is null. As far as I can tell, it
currently isn't, so this is merely fragile, not actually broken.
The robust way to do this is to receive the error in a local variable,
then propagate it up, like this:
Error *err = NULL;
... code that may set err ...
if (err)
... handle error ...
error_propagate(errset->errp, err);
}

qga_vss_fsfreeze() casts error_set_win32() from
void (*)(Error **, int, ErrorClass, const char *, ...)
to
void (*)(void **, int, int, const char *, ...)
The result is later called. Since the two types are not compatible,
the call is undefined behavior. It works in practice anyway.
However, there's no real need for trickery here. Clean it up as
follows:
* Declare struct Error, and fix the first parameter.
* Switch to error_setg_win32(). This gets rid of the troublesome
ErrorClass parameter. Requires converting error_setg_win32() from
macro to function, but that's trivially easy, because this is the
only user of error_set_win32().

Previously, running the .msi would unregister the QEMU GA VSS service if QEMU GA was already installed on the machine, and then register it only if QEMU GA was NOT previously installed. This behavior caused the service to be registered only after the INITIAL installation, and any subsequent run of the .msi (to redo, repair, or upgrade the installation) ended in the service being unregistered.
Now, the VSS service is still unregistered if QEMU GA is already installed (so that a fix or an update could be performed) but then it is registered again (if the GA is not being uninstalled) thus finishing the repair/upgrade correctly. Additionally, downgrading is now prevented. If a user would like to downgrade a version, he/she must uninstall the newer version first.

PCIAddress inforfation is obtained via SetupApi, which provides the

SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration

This is the most convinient way for a userspace service. The lookup is
performed for every volume available. However, this information is
not mandatory for vss-provider.
In order to use SetupApi we need to notify linker about it. We do not need
to install additional libs, so we do not make separate configuration

We should use GetVolumeXXX api to work with volumes. This will help us to
resolve the situation with volumes without drive letter, i.e. when the
volume is mounted as a folder. Such volume is called mounted folder.
This volume is a regular mounted volume from all other points of view.
The information about non mounted volume is reported as System Reserved.
This volume is not mounted and thus it is not writable.
GuestDiskAddressList API is not used because operations are performed with
volumes but no with disks. This means that spanned disk will
be counted and handled as a single volume. It is worth mentioning
that the information about every disk in the volume can be queried
via IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

We need qmp_quest_get_fsinfo togather with vss-provider, which works with
volumes. The call to this function is implemented via
FindFirst/NextVolumes. Moreover, volumes in Windows OS are filesystem unit,
so it will be more effective to work with them rather with devices.
