Add some extra protection when 'preparing' a group that doesn't yet
contain any menus. This can happen if you subscribe to a group that
doesn't yet exist.
It was possible to crash any application using
g_dbus_connection_export_menu_model() by requesting a non-existent
subscription group over the bus.
In practice this only happened in races -- where the proxy sees a group
that exists and queries it, but by the time it does, it's already gone.

When building the file attribute table info for local files, use
thumbnail paths in $XDG_CACHE_DIR/thumbnails/large in addition to
$XDG_CACHE_DIR/thumbnails/normal.
Failing to do this would cause an application that creates large
thumbnails by default to never find any value for
G_FILE_ATTRIBUTE_THUMBNAIL_PATH, with no
G_FILE_ATTRIBUTE_THUMBNAILING_FAILED set, which might cause the
application to either think thumbnailing is still in progress, or
blindly requeue thumbnail operations in a loop.
Large thumbnails are generally preferred, so we now default to the path
of a large thumbnail (in case both are present).

Sometimes the poll duration in the /socket/timed_wait test is slightly
bigger than the requested 100000, causing failures like:

We were using the user-passed value of the @property argument for
several purposes in g_settings_bind(): error messages, binding
uniqueness (ie: one-binding-per-property-per-object) and most
importantly, connecting to the detailed notify:: signal.
The user may pass a string like "property_name" when the property's
canonical name is "property-name". g_object_class_find_property() will
find the property under these circumstances, but a connection to
"notify::property_name" will not notice notifies emitted for
"property-name".
We can solve this by using the user's string to perform the lookup and
then using pspec->name for everything after that.

The newly-introduced functions, g_content_type_get_symbolic_icon() and
g_content_type_get_generic_icon_name() don't seem to be for Windows, at
least for now. So filter them out from gio.symbols on Windows.
Also, glocalfileinfo.c calls g_content_type_get_symbolic_icon() in
get_icon(), so only build that code when on Unix, for the time being.

Some programs attempt to use libglib (or even libgio) when setuid.
For a long time, GTK+ simply aborted if launched in this
configuration, but we never had a real policy for GLib.
I'm not sure whether we should advertise such support. However, given
that there are real-world programs that do this currently, we can make
them safer with not too much effort.
Better to fix a problem caused by an interaction between two
components in *both* places if possible.
This patch adds a private function g_check_setuid() which is used to
first ensure we don't run an external dbus-launch binary if
DBUS_SESSION_BUS_ADDRESS isn't set.
Second, we also ensure the local VFS is used in this case. The
gdaemonvfs extension point will end up talking to the session bus
which is typically undesirable in a setuid context.
Implementing g_check_setuid() is interesting - whether or not we're
running in a privilege-escalated path is operating system specific.
Note that GTK+'s code to check euid versus uid worked historically on
Unix, more modern systems have filesystem capabilities and SELinux
domain transitions, neither of which are captured by the uid
comparison.
On Linux/glibc, the way this works is that the kernel sets an
AT_SECURE flag in the ELF auxiliary vector, and glibc looks for it on
startup. If found, then glibc sets a public-but-undocumented
__libc_enable_secure variable which we can use. Unfortunately, while
it *previously* worked to check this variable, a combination of newer
binutils and RPM break it:
http://www.openwall.com/lists/owl-dev/2012/08/14/1
So for now on Linux/glibc, we fall back to the historical Unix version
until we get glibc fixed.
On some BSD variants, there is a issetugid() function. On other Unix
variants, we fall back to what GTK+ has been doing.

The async test had several problems:
- It created a proxy and did not launch a main loop, meaning that its
callback would usually not get called, or, if it did get called, the
test harness would have taken down the connection already, causing an
assertion failure when the proxy had an error.
- It was dependent on the proxy test to set up the server and would fail
because some properties were modified by that test.

"There is a potential race here that's really unlikely to happen, but
here we go: We are trying to read from the same socket in two threads.
Some data comes. That causes the poll() in both threads (above) to
finish running. Then the cancellable is checked above. We now find
ourselves here. Only one thread will read the data. The other will
block on this function. Then the user may cancel the cancellable while
we are blocked here, but we will stay blocked...."
If a named pipe is being read in message mode and the next message is
longer than the nNumberOfBytesToRead parameter specifies, ReadFile
returns FALSE and GetLastError returns ERROR_MORE_DATA.
Since the API doesn't allow to return both a GError and the number of
bytes read so far, it makes more sense to return nread, and let the
client call GetLastError() himself to check if ERROR_MORE_DATA.
The current alternative loses the nread information.

Any file handle created with FLAG_OVERLAPPED must have
ReadFile()/WriteFile() called with an OVERLAPPED structure.
Failing to do so will give unspecified results, invalid read/write or
corruption.
Without FLAG_OVERLAPPED, it is not possible to read and write
concurrently, even with two seperate threads, created by 2 input and
output gio streams. Also, only with FLAG_OVERLAPPED may an IO
operation be asynchronous and thus be cancellable.
We may want to call ReOpenFile() to make sure the FLAG is set, but
this API is only available since Vista+.
According to MSDN doc, adding the OVERLAPPED argument for IO operation
on handles without FLAG_OVERLAPPED is allowed, and indeed the existing
test still passes.

GThreadPool defaulted to 0 for max_unused_threads (meaning thread-pool
threads would exit immediately if there was not already another task
waiting for them), and 0 for max_idle_time (meaning unused threads

max_unused_threads).

g_async_initable_real_init_finish() was previously handling all
GSimpleAsyncResults, even if they weren't created by
g_async_initable_real_init_async(), and libnm-glib accidentally relied
on that behavior. So remove the g_simple_async_result_is_valid()
check.
Many (if not "almost all") programs that spawn other programs via
g_spawn_sync() or the like simply want to check whether or not the
child exited successfully, but doing so requires use of
platform-specific functionality and there's actually a fair amount of
boilerplate involved.
This new API will help drain a *lot* of mostly duplicated code in
GNOME, from gnome-session to gdm. And we can see that some bits even
inside GLib were doing it wrong; for example checking the exit status
on Unix, but ignoring it on Windows.

Rather than doing a two step first-check-the-GAsyncResult-subtype-then-

Finish deprecating the "handle GSimpleAsyncResult errors in the
wrapper function" idiom (and protect against future GSimpleAsyncResult
deprecation warnings) by adding a "legacy" GAsyncResult method
to do it in those classes/methods where it had been traditionally
done.
(This applies only to wrapper methods; in cases where an _async
vmethod explicitly uses GSimpleAsyncResult, its corresponding _finish
vmethod still uses g_simple_async_result_propagate_error.)

Originally, the standard idiom with GSimpleAsyncResult was to handle
all errors in the _finish wrapper function, so that vmethods only had
to deal with successful results. But this means that chaining up to a
parent _finish vmethod won't work correctly. Fix this by also checking
for errors in all the relevant vmethods. (We have to redundantly check
in both the vmethod and the wrapper to preserve compatibility.)

the same priority will run in the order in which they were queued.
