Move the header under the common GIO include directory.
Sorry if it breaks any build, you had to use the correct header path.

They are not allowed in the specification, and can lead to infinite
loops when parsing.
That’s a security issue if your application is accepting D-Bus messages
from untrusted peers (perhaps in a peer-to-peer connection). It’s not
exploitable when your application is connected to a bus (such as the
system or session buses), as the bus daemons (dbus-daemon or
dbus-broker) filter out such broken messages and don’t forward them.
Arrays of zero-length elements are disallowed in the D-Bus
specification: https://dbus.freedesktop.org/doc/dbus-specification.html#container-types

Glib cannot be built statically on Windows because glib, gobject and gio
modules need to perform specific initialization when DLL are loaded and
cleanup when unloaded. Those initializations and cleanups are performed
using the DllMain function which is not called with static builds.
Issue is known for a while and solutions were already proposed but never
merged (see: https://gitlab.gnome.org/GNOME/glib/-/issues/692). Last
patch is from version 2.36.x and since then the
"constructor/destructor" mechanism has been implemented and used in
other part of the system.
This patch takes back the old idea and updates it to the last version of
glib to allow static compilation on Windows.
WARNING: because DllMain doesn't exist anymore in static compilation
mode, there is no easy way of knowing when a Windows thread finishes.
This patch implements a workaround for glib threads created by calling
g_thread_new(), so all glib threads created through glib API will behave
exactly the same way in static and dynamic compilation modes.
Unfortunately, Windows threads created by using CreateThread() or
_beginthread/ex() will not work with glib TLS functions. If users need
absolutely to use a thread NOT created with glib API under Windows and
in static compilation mode, they should not use glib functions within
their thread or they may encounter memory leaks when the thread finishes.
This should not be an issue as users should use exclusively the glib API
to manipulate threads in order to be cross-platform compatible and this
would be very unlikely and cumbersome that they may mix up Windows native
threads API with glib one.
Closes#692
The gdbus-codegen tool generates documentation from the XML introspection
description of a D-Bus interface. Currently, only DocBook is supported at
the moment, but not every modern documentation generator can handle that
format. The reStructuredText format is a bit more well-supported,
especially in documentation generators for non-C languages.
Unlike DocBook, we get to make our own structure and conventions for how
we structure the documentation when using reStructuredText.
When parsing a comment we're adding <para> elements ourselves, but the
DocBook generator already wraps any block of text that does not start
with a <para> element with one.
xucred does not provide the peer pid id, but this can be fetched
from the socket LOCAL_PEERPID option. Note that we only support
it when creating the credentials from a local socket, if
the credential comes from a message over a socket the peer
pid id will not be set and -1 will be returned when trying
to get the pid for the credential.
D-Bus reference implementation doesn't require more than the claimed
process SID as part of the AUTH initial data for EXTERNAL.

This commit puts an additional underscore before the external symbol
`_g_binary_test1_resource_data` when using gcc for Windows, to match
the compiler's expectation.

Using ld_flags would work, but that does not propagate ldflags to users
of glib. Meson's dependency() call will propagate apple framework
dependencies to downstream users.
Not everything should be an int. This code is quite dated. We now try to
use `guint8*` to represent arbitrary binary data, rather than `guchar*`
(which makes it sound like some form of string).

While it’s not a supported public part of the API, exporting this
symbol from the library means we can easily test the DNS record parser,
which is important to do since it handles untrusted data from the
network.
This tests for #2503. It's fragile, but there is no non-fragile way to
test this. If the test breaks in the future, it will pass without
successfully testing the bug, not fail spuriously, so I think this is
OK.
We should run test_pass_fd twice, once using gspawn's fork/exec codepath
and once attempting to use its posix_spawn() codepath. There's no
guarantee we'll actually get the posix_spawn() codepath, but it works
for now on Linux.
For good measure, run it a third time with no flags at all.
This causes the test to fail if I separately break the fd remapping
implementation. Without this, we fail to test fd remapping on the
posix_spawn() codepath.
Specs say that on Unix id should be desktop file id from the xdg menu
specification, however, currently code just uses basename of .desktop file.
Fix that by finding the .desktop file in all the desktop_file_dirs and use
basename only as a fallback.
See https://specifications.freedesktop.org/menu-spec/latest/go01.html#term-desktop-file-id
and https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s02.html#desktop-file-id
"To determine the ID of a desktop file, make its full path relative to the
$XDG_DATA_DIRS component in which the desktop file is installed, remove the
"applications/" prefix, and turn '/' into '-'."
Also, add unit test that verifies Desktop Id is being correctly set

This is sad, but GResolver has one member variable for historical
reasons, to implement the reload signal. Since it offers a global
singleton, we should make sure it's really safe to use from multiple
threads at once.
This call was needed once upon a time, when GResolver had subclasses
that presumably relied on this. Nowadays, we have only
GThreadedResolver, which does not need it. res_init() is dangerous
because it modifies global state, so let's get rid of it.
