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.

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.

This was confusing some static analysis. Through canonicalize_filename()

Even though GetStartupInfo() in g_win32_run_session_bus() would
tell us that STARTF_FORCEONFEEDBACK flag is not set, it still
affects the rundll32 process for some reason.
This means that Windows WM changes mouse cursor to IDC_APPSTARTING for
a few seconds when rundll32 runs g_win32_run_session_bus(). Since
g_win32_run_session_bus() never satisfies the conditions set by
STARTF_FORCEONFEEDBACK, the busy cursor only goes away after a
timeout.
Fix this by explicitly running GetMessage(). To ensure that GetMessage()
doesn't block, post a quit message immediately before calling it.

Some applications support running in a mode where they present
themselves as a different application to the user (for example web
browsers or terminals).
To facilitate this, add an option --gapplication-app-id which allows

Applications need to opt-in to this by setting the

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
@dest_info.

I'm tired of seeing 'No such file or directory' in the logs without
a hint as to what is actually wrong. Including the filename here
may help me tracking down a bug in the continuous infrastructure.
Visual Studio, at least the older versions, cannot use L on macros which
are defined as a constant string, plus the L must be applied to all string
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
(due to a variable not being expanded) and would evaluate to "", which
would then cause things to be installed in the wrong place.

This reverts commit e5c752371c.
I think it is a recursion from the GUnixMountMonitor constructor, to a
GLocalFileMonitor on /etc/fstab, and into GUnixMountMonitor again, now
with a mutex already held, so it deadlocks.
https://bugzilla.gnome.org/page.cgi?id=traceparser/trace.html&trace_id=235354
That mutex in glocalfile.c:g_local_file_find_enclosing_mount() doesn't
seem necessary any more IMHO. Inside it, only 'mount' is modified, but
that's just a stack variable local to this function. When
klass->get_mount_for_mount_path is called, it's given one const
parameter and the other is unused, so they're unchanged. 'klass'
doesn't seem it could be modified either inside that function.
It doesn't recurse infinitely, but seems to work correctly and pass the
testsuite after this change.
The FreeBSD project already applied my patch in their ports tree, and
their users seem happy with it.

As g_win32_get_command_line() calls CommandLineToArgvW() to acquire the
arguments passed into a GApplication program, it actually returns the
whole command line which is used to invoke the program, including the
script interpreter and its flags when a script using GNOME bindings
(e.g. PyGObject and so on) is being invoked.
The issue here is that g_application_run() would most probably have
trouble in the scripts scenario on Windows as it is likely unable to
"recognize" the script interpreter, causing such scripts to fail to run.

Otherwise, we'll acquire it on every loop iteration, which can leave us
vulnerable to racing another thread for the acquisition of the main

This can break methods like g_main_context_invoke, which try to acquire
a context to figure out if it can invoke the method synchronously or
need to defer to an idle. In these cases, it isn't guaranteed that the
invocation function will be invoked in the default main context,
e.g. the one that GApplication is holding.
This also matches what GMainLoop is doing.

Recent changes to file monitors removed the delay before events were
reported. Among other things, this caused the trash backend of gvfs to
notice trashed files sooner than before.
On noticing trashed files, the backend tries to read the info file to
discover (among other things) the original location of the file.
Unfortunately, g_local_file_trash() does a strange dance when trashing a
file. It does a loop of open(O_EXCL) in order to file an empty filename
in the trash to write an info file to, trashes the file, and only then
writes the contents of the info file. This means that at the time the
file is moved to the trash, the info file is an empty stub.
Change the order so that we write out the actual content of the info
file first. If the actual trash files then we will unlink the info file
anyway.

Previously, GLib returned text/plain for empty files.
This is important because people may want to open empty (eg:
just-created) text files with the text editor.
An unintended side-effect of b6fc1df022

This commit is essentially a revert of that commit, with a different
solution: we move the special-case up a bit in the function and
hard-code it to text/plain.
This change does not exactly maintain the old behaviour: previously, a
"fast" lookup would have returned application/octet-stream on an empty

We don't need to run binaries we just built in order to successfully

This means that we don't need to check for existing, native binaries
when cross-compiling, and fail the configuration step if they are not
found — which also means that you don't need to natively build GLib for

gvfs commit b358ca "Make sure metadata is always returned by
query_writable_namespaces()" changed the
query_writable_namespaces vfunc to never return NULL, but the error
checking in g_daemon_file_query_writable_namespaces still assumes vfunc
failure implies NULL return value and GError set. This causes a memory
leak as on failure the GError will be set but the vfunc implementation
will have created its own default list so NULL will not be returned, and
the GError will never be cleared.
This commit directly checks if the GError is set to detect failures,
my_error is directly dereferenced in the error block anyway.
This also removes an unneeded call to g_file_attribute_info_new(); as
the vfunc always returns us a non-NULL GFileAttributeInfoList.

These tests clear up a misunderstanding of mine: Monitoring
nonexisting files and directories *does* work with the inotify
implementation, it just has a very long timeout for scanning
for missing locations, so the test needs to take that into
account.
This is meant for opaque, non-POSIX-like backends to indicate that the
URI is not persistent. Applications should look at
G_FILE_ATTRIBUTE_STANDARD_SYMLINK_TARGET for the persistent URI.
Examples of such backends could be a portal for letting sandboxed
applications access the file-system, or a database-backed storage like
Google Drive.
In these cases, the user visible file and folder names are different
from the real identifiers, used by the backend. So, a request to
create google-drive://user@gmail.com/foo/New\ File, would actually
lead to google-drive://user@gmail.com/foo/bar on the server even though
the user visible name is still "New File". Since the server-defined URI
is persistent and sanity-checked by the backend, it is recommended that
applications switch to it as soon as possible. Backends will try to
keep a mapping from "fake" to "real" URIs, but those are only on a

g_dbus_method_invocation_return_value(), etc, don't have GError
parameters (which makes sense since they won't usually return errors,
and there's not much you could do if they did), so in the rare case
when something does go wrong, they print a warning.
However, there is at least one situation where the warning is a bad
idea: if you are using private bus connections, and a client connects,
makes a request, and then disconnects before getting the response.
Given that there's nothing the caller can do to prevent this case from
getting hit (since the client might not disconnect until after the
call to g_dbus_method_invocation_return_value() starts) and given that
the server can never actually know for sure that the client has
received the response (it might disconnect after reading the response,
but before processing it), just kill the warning in this case.

Add a new test which checks that atomically replacing a file that
is being monitored by GFileMonitor produced the expected events.
The test can easily be expanded to cover other file monitoring
scenarios.
After the big file monitoring rewrite, we only put the IN_MOVED_FROM event
in the queue for such pairs. It matches INOTIFY_DIR_MASK and thus we call
ip_dispatch_event on it, but that function was filtering it out because
the filename in the 'from' event is the one of the temp file, not the
one we are monitoring. That name is in the 'to' event, so compare it as
well, and let the event passin that case.
There is another instance of this check in glocalfilemonitor.c, which is
corrected here as well.

exit-on-close for a DBus connection is a completely normal thing. On
a regular GNOME login, gdm retains the X server, but terminates the
session login bus and associated helpers like gnome-settings-dameon,
the a11y tools, etc.
I've seen several downstream reports of confusion as to what these
apparent error messages mean in the system log. It doesn't help
that they're so obtuse.
We're also printing them to stderr, when this is not an error.
The reason this was introduced is presumably some people were confused
as to why their process exited when the system bus did. But the
solution for that I believe is documentation, not printing stuff to
everyone's system log in normal operation.

Add a property to GNetworkMonitor indicating if the network

The default value is FALSE
https://bugzilla.gnome.org/show_bug.cgi?id=750282
A signal accumulator can return TRUE to continue signal emission, and
FALSE to stop signal emission. handle-local-options callbacks can return
« return a non-negative option if you have handled your options and
want to exit the process ».
Currently, g_application_handle_local_options_accumulator (the
accumulator for the handle-local-options signal) returns TRUE on
non-negative return value (ie continue signal emission), and returns
FALSE on negative return values (ie when the default option processing
should continue).
This return value seems backward as on >= 0 values, subsequent
handle-local-options callbacks could overwrite the 'exit request' from
the handler, while on < 0 values, the handle-local-options processing
could end up early if several callbacks are listening for this signal.
In particular, the default handler for this signal
(g_application_real_handle_local_options) always returns -1 and will
overwrite >= 0 return values from other handlers.
This commit inverts the check so that signal emission stops early when
one of the handle-local-options callbacks indicates it wants processing
to stop and the process to exit.

We already have start, stop and is_active methods, but turning it

In 4e7d22e268, deleting the file was moved
after the assertion which checks for the changed event that results from
it being deleted. This is the wrong way around and makes the assertion
fail.
Move the deletion back up before we check the condition. delete_app is
no longer an idle callback so it can be made void. The change
notification might come in when the loop isn't running now, so don't try
to quit if it isn't running. In this case we'll wait for the three

This is the right thing to do for the "a session is a user-session"
model implemented in dbus 1.9.14, which is described in
<http://lists.freedesktop.org/archives/dbus/2015-January/016522.html>.
It also resembles sd-bus' behaviour, although sd-bus will only try
kdbus and XDG_RUNTIME_DIR/bus, and never runs dbus-launch.
On systems following the more traditional "a session is a login-session"
model, X_R_D/bus won't exist, so it is harmless to check for it before
falling back to X11 autolaunching. Again, this matches the behaviour
of current libdbus and sd-bus versions.
Now that we do this, g_test_dbus_unset() needs to clear XDG_RUNTIME_DIR
as well as everything else.

This only alters what happens if we specifically connect to
"autolaunch:", for instance via "DBUS_SESSION_BUS_ADDRESS=autolaunch:".
We will still potentially try other platform-specific things if
DBUS_SESSION_BUS_ADDRESS is unset. There are currently no other
platform-specific things, so there is no practical difference yet,
but I'm about to add a more-preferred fallback path before autolaunch.
This matches libdbus' behaviour and the D-Bus Specification, in which
the autolaunch: transport specifically means X11 autolaunch
(as implemented by "dbus-launch --autolaunch") on Unix, or a
shared-memory-based protocol on Windows. Other platform-specific
transports or default/fallback modes, including launchd on Mac OS X
and XDG_RUNTIME_DIR/bus on Unix, are not part of "autolaunch:".
It's rather unfortunate that the same name means two different
platform-specific mechanisms, specific to different platforms -
if they were added today I'd call them x11: and windows-shm: or
something - but it's been like this since 2007 so it's too late now.

Use the newly added g_settings_schema_list_keys() API instead of
g_settings_list_keys() in order to list keys.
Doing this allows the 'list-keys' command to work without creating a

relocatable schemas.

In order to maintain a logical stream of events, we need to make sure we
flush and queued change notifications before responding to any requests
for information from clients.
If we don't do this, it's possible that we emit an 'add' event that was
queued at the time of a 'DescribeAll' call _after_ the reply to that
call (which already contained the description of the new action).
In practice, this is not only logically incorrect, but it can also cause
problems. If a change to action 'state' or 'enabled' occurs after the
DescribeAll but before the signal has been dispatched, it will be
ignored because an 'add' signal is already pending. When that add
signal is sent, it will contain the correct data, but the receiver will
ignore it because it already saw the action in the DescribeAll reply.

The code here was returning gtk-directory and similar names as
fallback, with a comment claiming that these are 'builtin gtk'.
But they aren't, anymore, so just return the standard names.
This code used to look at the SCM_CREDENTIALS and ignore every message
not from uid 0. However, when user namespaces are in use this does not
work, as if uid 0 is not mapped you get overflowuid instead. Right now
this means we ignore all messages in such user namespaces and glib
apps hang on startup.
We can't look at pids either, as pid 0 is returned for processes
outside your pid namespace.
Instead the correct approach is to look at the sending sockaddr and
if the port id (nl_pid) is zero, then its from the kernel.

When test_double_array() was added, environments like the Debian

Always run the full algorithm for a given mime type before considering
fallback types.
This includes considering installed applications capable of handling a
particular mimetype, even if such an app is not explicitly marked as
default, and there is a default app for a less-specific type.
Specifically, this often helps with cases of installing apps that can
handle a particular subtype of text/plain. We want to take those apps
in preference to a generic text editor, even if that editor is listed as
the default for text/plain and there is no default listed for the more
specific type.
Because of the more holistic approach taken by the algorithm, it is now
more complicated, but it also means that we can do more work while
holding the lock. In turn, that lets us avoid duplicating some strings,
