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.

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

- 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

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

client call GetLastError() himself to check if ERROR_MORE_DATA.

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

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

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

platform-specific functionality and there's actually a fair amount of
boilerplate involved.

Originally, the standard idiom with GSimpleAsyncResult was to handle

to deal with successful results. But this means that chaining up to a

for errors in all the relevant vmethods. (We have to redundantly check
in both the vmethod and the wrapper to preserve compatibility.)

Prevent attempts to access keys ending with slashes that exist in the
schema file as references to child schemas.
Also: don't emit change signals for these same keys.
For a D-Bus property with name "Type" (fairly common), we used to
generate a GObject property with name "type-" and C accessors
get_type_() (to avoid clashing with the GType getter), set_type_()
(for symmetri).
However, the rules for GObject property names are fairly rigid and
specifically prohibit names ending in a dash.
Therefore change things so the chosen GObject property name is "type"
but preserve the naming rules for the C getter and setter (for the
same reasons: avoiding name clashing and symmetri).
This change does break the API of generated code (but only on the
GObject property level, the C symbols are not changed) but strictly
speaking the behavior was undefined since "type-" was an invalid
GObject property name.
Also add a test case for this.

Reading from a GConverterInputStream with both input_buffer and
converted_buffer non-empty would return bogus data (the data from
converted_buffer would essentially get skipped over, though the
returned nread reflected what the count would be if it hadn't been).
This was never noticed before because (a) it can't happen if all of
your reads are at least as large as either the internal buffer size or
the remaining length of the stream (which covers most real-world use),
and (b) it can't happen if all of your reads are 1 byte (which covers
most of tests/converter-test). (And (c) it only happens for some
converters/input streams.) But this was happening occasionally in
libsoup when content-sniffing a gzipped response, because the

then pass through larger reads after that.
