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This change was originally made to work around a race condition in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
them on non-*NIX platforms. Also clean up gio/Makefile.am a bit to split out
the listings for the platform-specific sources from the platform-neutral
sources, and assemble them for the final list of sources required for libgio.

OS X apparently stringifies the IPv6 address "::80" as "::0.0.0.128",
which is bizarre, but that address *is* in a "reserved for future use"
range, so it's not unambiguously wrong I guess. Anyway, fix the text
to use an address everyone can agree on.

The backend for this lives in xdg-desktop-portal,
and is in turn using GNetworkMonitor.
When network is not available in the sandbox, there is
no point in reporting accurately about the network
status outside the sandbox. Just return 'no connection'
in this case.

We need to patch in the portal support at a high enough
level that GAppInfo is not involved - a sandboxed app may
not be able to see any applications, so it can only launch
the defaults.
Note that even though the API is called launch_default...,
the portal may still offer the user to choose the application
to launch.

These are private helper functions that will be used in
the following commits to get information about whether
we are running in a flatpak sandbox, etc.
We allow the use of GTK_USE_PORTAL=1 in the environment
to force the use of portals. This can be useful for
testing and debugging portal interaction.

This command collects the various commandline utilities that
are currently shipped in gvfs, and unifies them under a single,
command-style binary.
The tools just use GIO APIs, so it makes sense for them to live here.
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:

The list of supported schemes is not known at compile-time, so it is
wrong to iterate the list with G_N_ELEMENTS() and we miss all but the
first scheme. Fix by checking for the %NULL sentinel instead.

Add filesystem attribute to detect remote filesystems in order to
replace hardcoded filesystem types in GtkFileSystem. Set this attribute
also for GLocalFile appropriately.
Bump version to 2.49.3, so that early adopters of new API have a version
number to target.
If none of the closures in the hash table return a non-null value, the
loop never ends. Since the end of the hash table has been reached at
that point, g_hash_table_iter_next() starts asserting.
The possible fix is making the return value of g_hash_table_iter_next()
the condition in the loop.

Add a new API to allow clients to register a custom GFile implementation
handling a particular URI scheme.
This can be useful for tests, but also for cases where a different URI
scheme is desired to be used with another custom GFile backend.
As an additional cleanup, we can use this to register the "resource" URI
scheme too.
Based on a patch by Jasper St. Pierre <jstpierre@mecheye.net>.

5cea1c861d introduced accessors for 64bit
ints to gsettings, at which point the testcases were expanded.
Unfortunately, the expanded tests contained a bug: integer constants
passed to g_object_set() for a 64-bit property need an up-cast. Add
that now.
Problem found by Iain Lane.
This makes it easier to use GKeyFile from language bindings, and makes
the API more consistent and modern with the new data type available in
GLib.

The ability to pass libtool via $(CC) to dtrace and have it respect this
appears to be a feature that is only present in the systemtap version of
the tool. In particular, FreeBSD (which seems to be using a copy of the
tool from Solaris) doesn't support this.
The result is that, with $(CC) ignored, and a .lo file specified in -o,
we get an ELF written to the .lo.
Instead of trying to have dtrace run libtool we can have libtool run
dtrace. dtrace is really just a compiler that produces an object file
here, and it even understands -o, so libtool can make the appropriate
adjustments.
There appears to be some prior art for this approach. A quick search
shows that at least QEMU is using this approach. It also appears to
work on Linux with systemtap's dtrace and on FreeBSD.
This may regress cross-compilation because the dtrace command will have
no way of knowing which compiler we intend for it to use to produce the
object file. I say "may" because I don't know if dtrace ever worked in
the first place under cross-compilation.
