The two known use-cases for autolaunching are:
* X-forwarding: "ssh -Y myhost myapp" resulting in a
session bus on myhost but an X server on the original host
* Legacy desktop environments on OSs without D-Bus integration:
e.g. running a single GNOME or KDE app under fvwm or something,
without a session dbus-daemon being started by either systemd,
gnome-session, or OS integration scripts analogous to Debian's
/etc/X11/Xsession.d/75dbus_dbus-launch
In either case, an X11 DISPLAY is also needed.
"dbus-launch --autolaunch" doesn't do anything useful when unable
to connect to an X11 display; this has been the case since the feature
was added in 2006, and is useful to avoid "split brain" situations in
which two processes that ought to be part of the same session end up
on separate session buses. Since dbus commit 407c111 in 2011,
libdbus hasn't even attempted to run "dbus-launch --autolaunch"
unless getenv("DISPLAY") returns non-null in the parent: this avoids
doing a relatively complicated fork-and-exec that is clearly not
going to lead to success. This commit gives GDBus the same policy.
This change was originally made to work around a race condition in
subprocess spawning (Debian bug #737380, GNOME bug #711090) but
it seems valid in its own right.
In my opinion as D-Bus maintainer, "dbus-launch --autolaunch" should
be considered to be an X11 feature, and any future D-Bus enhancements
(e.g. kdbus) or successors for X11 (e.g. Wayland, Mir) should obtain
a session bus address by other means - either a session manager
such as "systemd --user", gnome-session or Upstart, or a wrapper
for the user session like dbus-run-session(1).

xdg-desktop-portal support is only usable on *NIX platforms, so don't build

OS X apparently stringifies the IPv6 address "::80" as "::0.0.0.128",

We need to patch in the portal support at a high enough

In a vague attempt at ensuring the .stp scripts can be closely
associated with the .so files which they hard-code references to, rename
the scripts so they include the LT version — so that they are the .so
file name plus .stp.
This does not fix the fact that our .stp scripts will not work on
multiarch systems, as they are installed in an architecture-independent
directory (/usr/share/systemtap/tapset). At the moment, it is
recommended that any distribution who package the .stp files should
install them in the architecture-specific subdirectories of this (for
example, /usr/share/systemtap/tapset/x86-64).
A better long-term solution for this is under discussion upstream:

This adds a new --c-generate-autocleanup option to gdbus-codegen
which can be used to instruct gdbus-codegen about what autocleanup
definitions to emit.
Doing this unconditionally was found to interfere with existing
code out in the wild.
The new option takes an argument that can be
none, objects or all; to indicate whether to generate no
autocleanup functions, only do it for object types, or do it
for interface types as well. The default is 'objects', which
matches the unconditional behavior of gdbus-codegen on the 2.48
branch.

The use of past tense in g_task_had_error makes one assume that it
won't forget about any errors that might have occurred. Except, in
reality, it would.
Let's use a boolean flag to remember the error once it's been

the g_task_propagate_* methods continue to give invalid results when
called more than once, as mentioned in the documentation.

Some GNOME projects unconditionally work around the generated code's
lack of g_autoptr support by defining the autoptr cleanup function
themselves, which is not forward-compatible; as a result, commit
cbbcaa4 broke them. Do not define the cleanup function unless the
including app "opts in" to newer APIs via GLIB_VERSION_MAX_ALLOWED.
Projects requiring compatibility with GLib < 2.49 can get a
forward-compatible g_autoptr for a generated GInterface type found in
a library, for example ExampleAnimal in the GIO tests, by declaring
and using a typedef with a distinct name outside the library's
namespace:
typedef AutoExampleAnimal ExampleAnimal;
G_DEFINE_AUTOPTR_CLEANUP_FUNC (AutoExampleAnimal, g_object_unref)
...
g_autoptr (AutoExampleAnimal) animal = NULL;
/* returns ExampleAnimal * */
animal = example_animal_proxy_new_sync (...);

gdbus-tool prints a hint about the expected arguments to a function call
in case of errors. Unfortunately, it prints this message on all errors.
I've seen this confuse users several times -- they go on tweaking the
arguments trying to get the correct type, even though they had it
correct in the first place.
Let's limit the hint to the case where it was actually invalid arguments
that triggered the problem. Also, adjust the code that prints the
message so that it will also report on the case that no arguments were
expected.
We could possibly get closer to what we want by comparing the list of
expected arguments with the parameter list, as it was parsed from the
user, but that would involve composing the expected type. Let's keep
this simple for now.

When debugging a program or testing a change to an installed version, it
is often useful to be able to replace resources in the program or a
library, without recompiling.
To support this, for debugging and hacking purposes, it's now possible
to define a G_RESOURCE_OVERLAYS environment variable as a
colon-separated list of substitutions to perform when looking up
GResources.
A substitution has the form
"/org/gtk/libgtk=/home/desrt/gtk-overlay"
The part before the '=' is the resource subpath for which the overlay
applies. The part after is a filesystem path which contains files and
subdirectories as you would like to be loaded as resources with the
equivalent names.
In the example above, if an application tried to load a resource with
the resource path '/org/gtk/libgtk/ui/gtkdialog.ui' then GResource would
check the filesystem path '/home/desrt/gtk-overlay/ui/gtkdialog.ui'. If
a file was found there, it would be used instead.
Substitutions must start with a slash, and must not have a trailing
slash before the '='. It is possible to overlay the location of a
single resource with an individual file.
https://bugzilla.gnome.org/show_bug.cgi?id=765668
Replace the hand-written equivalent of this with the call to the
GHashTable built-in version to save a few lines of code.
The GResource code was written a couple of years before this function
existed.
Similarly, replace a set-mode usage of g_hash_table_insert() with a call
to g_hash_table_add().

GContextSpecificGroup has been somewhat broken for a rather long time:
when we remove the last reference on an object held in the group, we try
to clean up the source, but fail to actually remove it from the
mainloop.
We will soon stop emitting signals on the source (due to it having been
removed from the hash table) but any "in flight" signals will still be
delivered on the source, which continues to exist. This is a problem if
the event is being delivered just as the object is being destroyed.
This also means that we leave the source attached to the mainloop
forever (and next time will create a new one)...
This is demonstrated with the GtkAppChooser dialog which writes an
update to the mimeapps.list file just as it is closing, triggering the
app info monitor to fire just as it is being destroyed.
Karl Tomlinson correctly analysed the problem and proposed this fix.

GApplication has accepted any valid bus name as an application ID since
before the time of D-Bus activation. This includes bus names with '-'.
Several applications have even attempted support bus activation with
these names, going as far as installing D-Bus service files, without
realising that they are silently falling back to fork()/exec() on
account of the name containing a dash.
The reason for the problem is that D-Bus object paths cannot contain
dashes. We solved this problem privately in an unspecified way inside
of GApplication but substituting '_' in this case, but never made this
part of the Desktop Entry Specification.
The fact that these apps with '-' in the desktop file names aren't
actually using D-Bus activation is beside the point: their intent here
was clear. Let's avoid forcing them to rename their desktop files again
by simply accepting '-' in desktop file names and munging the path in
the way that GApplication did so historically.
The new path escaping code here has been copied more or less verbatim
from GApplication's own code for the same purpose, with only the removal
of one irrelevant part.
An update to the desktop entry specification will follow.

Even though GetStartupInfo() in g_win32_run_session_bus() would

Perform conversion before writing a value out of the cache into the registry,
and convert back when reading a value into the cache out of the registry.
The registry holds UTF-8 strings.
This is a flag used to understand if a key exists on the registry
and if it is readable. It makes more sense to rename it as readable
since anyway a key that does not exists anymore is a key that is
not readable.
The documentation of g_file_info_copy_into() was misleading. The
attributes are not just copied, @dest_info is also cleared at the
beginning. So any previously set attributes in @dest_info are lost.
There was a bug in gedit about this function, where some metadata were
not saved. So it might make sense to change the implementation to not
clear @dest_info, and copy one by one the attributes from @src_info to

Visual Studio, at least the older versions, cannot use L on macros which

literals here. This does not look nice, but this is life...
Rather than calculating it at configure time. This means it can expand
$libdir properly, and use the Make $(realpath) function rather than
invoking the non-portable `readlink -f`.
This fixes problems where `readlink` would be called on an invalid path

would then cause things to be installed in the wrong place.
