Rather than tracking them with a counter. This should close the race in

There’s no way to synchronise with that thread as it’s internal to

This allows the controller to explicitly be removed from the bus, in a
way that allows the caller to synchronise with it and know that all
other references to the controller should have been dropped (i.e. after
this method returns, there should be no in-flight D-Bus calls still
holding a reference to the object).
This is needed to be able to guarantee finalisation of the controller in
unit tests (and comparable real-world situations).

The resources data is generated for both GCC and MSVC toolchains, even
though we know beforehand which toolchain we're going to compile it for.
By dropping the data duplication we make the generated resources file
faster to compile, especially when dealing with large embedded data,
instead of relying on the C pre-processor to walk the whole file and

If `GDebugControllerDBus` remains as the only, or default,
implementation of `GDebugController`, `dup_default()` cannot work.
`GDebugControllerDBus` requires a `GDBusConnection` at construction
time, which the `GIOModule` construction code can’t provide it.
Either we use a default D-Bus connection (but which one? and how would
it be changed by the user later if it was the wrong one?), or delegate
singleton handling of the `GDebugController` to the user.
The latter approach seems more flexible.

On Windows, dbus is launched by spawning the gdbus.exe executable on
demand from the gio module. When linked dynamically, the executable
path is guessed relatively to the gio DLL path. But when linked
statically, the only reference path available is the current
executable path. In this case, gdbus.exe is not necessarily in the same
folder as the current executable.
This patch solves the issue using the same algorithm as the one used
with process spawning in glib core source code two commits above.
This is intended to provide a uniform interface for controlling whether
the debug output from an application (or service) is emitted, typically
to journald, but actually to wherever the application chooses to output
it.
The main implementation of `GDebugController` is `GDebugControllerDBus`,
which is intended to be used on Linux. Other implementations may be
added in future for other platforms, or larger applications may want to
provide their own implementation which integrates with their ecosystem.
The `GDebugControllerDBus` implementation exposes a D-Bus interface at
`/org/gtk/Debugging` with a method to enable or disable debug
output at runtime.
This could be used by external harnesses, such as GNOME Builder or
systemd, to give a uniform way to get debug output from an application.

That’s a security issue if your application is accepting D-Bus messages

exploitable when your application is connected to a bus (such as the

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.

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.

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.

We used to use a pipe for the dbus daemon stdout to read the defined

However the current implementation is still causing troubles in some

to stdout.
As per this, just don't handle stdout ourself, but use instead a
specific pipe to get the address address. That can now be safely closed
once we've received the data we need.

Perform strict bounds checking when reading data from the D-Bus message,

Previously, truncated D-Bus messages could cause out-of-bounds reads.
This is a security issue, but one which is only exploitable when
communicating with an untrusted peer (who might send malicious
messages). Almost all D-Bus traffic is with a session or system bus,
where the dbus-daemon or dbus-broker is trusted, and is known to have
already rejected malformed (malicious) messages.
Accordingly, this is only exploitable with peer-to-peer D-Bus
conversations with an untrusted peer.

Since
https://gitlab.gnome.org/GNOME/glib-networking/-/merge_requests/173,
there is now a really surprising implication to using a non-default
GTlsDatabase: your database could do nothing at all other than wrap the
default database, which you would expect to result in no behavior
changes, but in fact it causes fewer security checks to be performed
during certificate verification. This is because certificate
verification moved from GTlsDatabase to GTlsConnection, allowing for
more security checks to be performed. But if using a non-default
GTlsDatabase, we have to fall back to letting GTlsDatabase to the
verification, as before.
This is the best we can do. It's not a regression for applications,
because it means applications get the previous pre-2.72 behavior. But it
does mean that new security checks added in 2.72 are not applied, which
is unfortunate, so we should warn developers about this.
This feature has been reverted for now because I messed up the
implementation and it was doing sync I/O during async API calls. Oops!
Since it's not present in 2.70 nor in 2.72, let's remove the reference
to the exact GLib version that this behavior was introduced in. I'd like
to get it working properly for 2.74, but it's not ready yet and just
changing the version to 2.74 feels optimistic.
Rather than waiting for a fixed period of time, poll in a loop until the
condition the test is expecting is true.
A better solution would be to use a `GSource` and wait until that’s
dispatched. But doing so might affect the behaviour of the
`GInputStream` under test, so busy-wait instead.

This was previously done (by commit 63038d1e4c) in one of the cases
where `kill_test_service()` was called — but not the other.
This meant that one instance of `gdbus-testserver` could still be
around when (as it happens, due to the order of the tests) the
`/gdbus/proxy/no-match-rule` test was run. It would start a second
instance of `gdbus-testserver`, which would exit early due to the test
name still being owned on the bus. The first (killed) instance of
`gdbus-testserver` would then exit, leaving no test servers running, and
hence the new test would fail.

all the data related to that object/subtree.
Unregistering the object/subtree would immediately free the data,

maybe error with --fatal-meson-warnings.
There are two basic solutions to this problem:
- The current default behavior is false, so explicitly opt in to that
value. None of these internal libraries use recursive objects anyway.
- Use link_with to link to the static library directly, rather than the
extracted objects.
Option 2 is what used to be done before commit
62af03bda8, but it only works with meson
>=0.52 and previously had buggy behavior.
Since the minimum version of meson is now 0.52, it is safe to revert
that commit and go back to using link_with, and therefore option 2 is
chosen.
Previously, the code validated that child objects have a path with the
object manager strictly as a prefix. That doesn’t work in the case where
the object manager’s path is `/`. This case is not recommended, but is
supported.
If the object manager’s path is `/`, validate that child objects’ paths
are not equal to it. If they are equal to it, warn the user rather than
emitting a critical warning, since we can’t expect any users who’ve not
been compliant with the spec to instantly rework their D-Bus APIs.

Emit this when we're about to spawn or DBus activate a GAppInfo. This
allows lauchers to keep the appinfo associated with a startup id.
We use a GVariant to allow for future exansion of the supplied data.
When using g_desktop_app_info_launch_uris_as_manager the "launched"
signal allows to map a desktop-startup-id to a GAppInfo. Make this
possible for DBus activation too.
Since we don't have a PID there we pass a 0. Update the signal
description accordingly.
These should be implemented by loadable IO module libraries, but are not
callable in GLib itself.

This is a partial revert of commit
f378352051, as the previous commits have
silenced the AddressSanitizer warnings for `GContentType`.
