The GApplicationCommandLine DBus implementation currently calls
g_dbus_method_invocation_return_value() in its finalize() implementation
only, relying on the object being destroyed after g_object_unref() is
called on it inside g_application_impl_method_call().
While this is usually fine for C applications, when overriding the
command_line vfunc from language bindings, the binding might add extra
references to the object, which might not be released immediately - e.g.
because they're garbage collected, or possibly even leaked. The same
scenario could happen in a C application that decides to keep a
reference to the passed-in GApplicationCommandLine object.
To ensure the CommandLine DBus method always gets a reply after the
invocation of command_line in the primary instance, explicitly send the
message back before dropping our reference to the object.

It's not difficult to do; not all backends implement it, and for some
it may be difficult to implement query_info_on_read(), so let's just
do both.

Add a pair of functions to make it easier to do simple string matching.
This will be useful for use with things like GtkSearchBar and will also
be the basis of the searching done by the (soon to appear)
g_desktop_app_info_search()

When the source id reaches G_MAXUINT (just prior to overflow), we
record the existing source ids to prevent reassigning them. As we are
about to assign G_MAXUINT to the triggering source, that id should be
added as well.

Since it could confuse callers (admittedly who are already violating
a precondition).
Just spotted while adapting some bits of this code for a ssh library.
GBindingTransformFunc called its arguments "source_value" and
"target_value", but in the transform_from function of a bidirectional
binding, "source_value" comes from the target object, and
"target_value" comes from the source object, which quickly gets
confusing if you need to use g_binding_get_source(), etc, in the
function.
Of course developers can call their transform function arguments
whatever they want, but many will copy from the headers/docs to start
out, so use less confusing names here ("from_value" and "to_value").
Also, fix the documentation to describe the bidirectional case
correctly.

This commit factors out a function for comparing string suffixes, and at
the same time makes it safe for mime types that are shorter than the
"/*" suffix.

Rather than having lots of obscure platform-based #ifdefs all over
gio, define some macros in gcredentialsprivate.h, and use those to
simplify the rest of the code.

Sometimes the application doesn't want to autostart a service
when it creates a proxy, but wants the service autostarted when
it makes the first method call. Allow that behavior with a new

Fix up a lot of whitespace issues in this file since we're about to do
some pretty serious rewriting here anyway...
Add some fold markers while we're at it.
Change the search path to be a global array of 'DesktopFileDir' structures and
change the 'get' function to an 'ensure' function.
This is just a straight-up refactor. Future patches will expand the
DesktopFileDir structure.
Add a convenient and race-free method of watching local files from the
GLib worker thread.
Without this, the race-free way to create a monitor that dispatches
events to the worker thread looked something like this:
- dispatch an idle to the worker thread
- from the idle, create the monitor and connect signals
- from the original thread, wait (on a cond?) until the worker thread
has finished setting up the monitor
- read the file that you were monitoring
which is just ridiculously complicated...
To use the new API:
monitor = g_local_file_monitor_new_in_worker ("/path/to/some/file",
G_FILE_MONITOR_NONE,
&error);
g_assert_no_error (error);
g_signal_connect (monitor, "changed", G_CALLBACK (callback), NULL);
g_local_file_monitor_start (monitor);
'callback' will run from the GLib worker thread.
This is the reason that the start() call was introduced in the previous
commit. The backends that don't use the start() call will have a very
thin race between creating the monitor and connecting the signal, but
hopefully they will be fixed soon.
These new APIs will be used (at least) from gdesktopappinfo to watch for
changes in the desktop file directories.
https://bugzilla.gnome.org/show_bug.cgi?id=704887
and start using the new start() vcall on the local monitor classes.
I only port inotify because I am uncomfortable making changes to the
other monitor backends without having a way of testing them.
https://bugzilla.gnome.org/show_bug.cgi?id=704887
Stop abusing constructor() to do startup work, adding _start() calls
instead.
The backends themselves still use constructor() although a patch will be
following to also fix inotify.
The reason for using a separate start() call instead of constructed()
will become apparent in future commits.

During initialisation of a directory monitor with the
G_FILE_MONITOR_WATCH_MOUNTS flag set, GLocalDirectory monitor will add a
UNIX mount watch in case the file notification backend doesn't support
reporting these events for itself.
Unfortunately, it was performing the check incorrectly, resulting in a
monitor always being added.
Fix that, and add the #define for G_LOCAL_DIRECTORY_MONITOR_GET_CLASS()
that was also missing (since the fix depends on it).

Matthew Barnes noted this on IRC a few days ago. I just had this file

Don't return children with invalid schemas from
g_settings_list_children() (ie: missing schemas or mismatched paths).
This prevents gsettings list-recursively from crashing when broken
schemas are installed on the system.

Add NULL check and return after calls to g_param_spec_internal in GParamSpec
creation functions. This avoids glib crashing due to things like badly named

This stack exists only to answer the question of "what is the currently
dispatching source" and is handled in a way that makes it very clear
that we don't need to be using a linked list at all...
Just store the GSource directly.

There are some corner cases where using the sync version of read/write
in a thread could cause thread-safety issues. In these cases it's
possible to override the output stream's splice_async() function,
but for input streams one would need to do some acrobatics to
stay thread-safe. Alternatively, some implementations may not even
override their sync read/write functions.
This patch refactors the default splice_async() implementation to
call the sync read and write functions in a thread only when both
async versions are thread-based. When one or both are non-threaded,
it calls the virtual write_async() and read_async() functions of the
involved streams within the same thread.
https://bugzilla.gnome.org/show_bug.cgi?id=691581
Refactor g_output_stream_close_async() into itself and an internal
variant for potential use inside other operations (splice_async).
The internal version must be called between
g_output_stream_set_pending() and g_output_stream_clear_pending().
https://bugzilla.gnome.org/show_bug.cgi?id=691581
Previously, no testcases tested the close flags of
g_output_stream_splice_async. This patch adds tests for that and
also tests various combinations of threaded and non-threaded
GInputStream async reads and GOutputStream async writes.
https://bugzilla.gnome.org/show_bug.cgi?id=691581
In implementing a better g_output_stream_splice_async() and possibly
other situtations it's helpful to know whether the output stream's
write function internally uses threads. If it and the input stream's
read async functions use threads, then the splice function could
spawn a single thread for better efficiency.
This patch adds a function to determine whether an output stream's
g_output_stream_write_async() function internally uses threads.
