Specific changes
- Use get_type(), not get_gtype() for the GType function
- so we need to use the lower-case name type_ for properties called type
- Don't return a function pointer, just make the function returned
available instead
- Add (type) annotations in constructors so g-ir-scanner detects them as such
- Add (transfer none) annotations to property getters
- Add (out) annotations to D-Bus method call functions

It's not that it's actually a bug to do so per se, strictly speaking,
it's just pointless and wasteful.

A fairly typical pattern is to have code that does
foo_set_bar (object, "");
if (some_condition)
{
foo_set_bar (object, "yes");
}
where some_condition is often true every time @object is updated.
With this code, bar is essentially always "yes" but because of how
gdbus-codegen works, useless PropertiesChanged events got scheduled
and sent out. With this patch, we avoid that by always keeping the
original value around and comparing it only when we deem it's time to
send out the ::PropertiesChanged signal (typically in an idle but can
be forced by the user via flush()).
Also add a test case for this.

Older versions of libdbus would let you construct an invalid
DBusMessage, but that's a bug, which will be fixed in 1.4.8/1.5.0.
Instead, construct a valid message of the same length, then replace
substrings in the serialized blob with their invalid counterparts.

If g_bus_get_sync() fails in authentication (because e.g. the process
uid, doesn't match the expected in EXTERNAL), a secondary call to
g_bus_get_sync() would notice we aren't initialized, and try
to initialize.
The assertion here is just wrong; we now explicitly and clearly handle
both cases where we already have an error, or we already succeeded.

Call g_settings_sync() just before g_applcation_run() returns. This is
really the correct thing to do in every case that you're using GSettings
and it prevents every single application from having to do it for
themselves.
Closes bug #647419.
If GSettings is uninitialised then g_settings_sync() should very
obviously just return right away (rather than attempting to initialise
GSettings first).
Add a flag to essentially short-circuit g_application_register(). The
application makes no attempt to acquire the bus name or check for
existing instances with that name. The application is never considered
as being 'remote' and all requests are handled locally.
Closes#646985.
Several flaws were pointed out by Shaun McCance. We were
leaking handled arguments, and we were mishandling the last
argument, and we were actually skipping arguments too.

When using GOption to handle commandlines, we need to disable
the builtin help handling, since it calls exit(). Also mention
this particular pitfall in the docs.
For child schemas, verify that the named schema actually exists and
issue a warning if not. This error in schema files will cause runtime
errors when iterating over the list of child schemas and attempting to
instantiate each one.
This will move from being merely a warning to a hard error in the
future.
Bug #646039.
g_tls_certificate_list_new_from_file() was leaking the file contents,
and GSource was leaking the GSourcePrivate structure that got
created when using child sources.
Without getting into a debate about the reasons why you may or may not
want to use unsigned integers, it's sufficient to note that people have
been using them and requesting this functionality.
Bug #641755.
If we have an expected interface and receive a signal not mentioned in
the interface, simply drop it. This way, the application won't have to

We were considering explicitly configured defaults for parent types
after we already got results for the specific type we're interested in.
This resulted in the explicit default for text/plain to override all
system defaults for subtypes of text/plain, for example. The explicit

Some people are trying to write code that calls g_application_register()
then checks to see if we became the primary name owner before exporting
objects. This sort of approach worked with libdbus-1 because method
calls to the freshly-acquired name would not be dispatched until the
application returned to the mainloop. With GDBus, however, dispatches
can occur at any time (including in the brief space between acquiring
the name and actually registering the object).
Add documentation to make it clear that you should not expect this to
work.
The existing docs are a bit inconsistent in that they say to follow
the dbus convention, but then give an example that doesn't.
This commit changes things to be how Ryan says they should be.
There are now fallback functions in the Win32 portion of
g_app_info that were previously only available under UNIX,
so add them here so that they can be exported as well.

g_app_info_get_recommended_for_type
If code creates a GDesktopAppInfo via g_desktop_app_info_new_from_keyfile(),
we'd try to send a NULL pointer down into GVariant.
Since in this case we don't have a filename, just send the empty
string. In the future we should either:
1) Change panel to use g_desktop_app_info_new_from_filename(), and
take the hit of parsing the file twice.
2) Add a g_key_file_get_origin_filename()
3) Add g_desktop_app_info_new_from_keyfile_and_name()

This property is now a GList of GByteArray values. Each

A new GDesktopAppInfo specific function which provides more control
over launched processes. Intended basically only for use in GNOME
Shell, where we want:
*) To directly know the GPid for each launched program, without
having to listen to a DBus signal emitted in our own process
*) Possibly control over the process environment; for example,
we may want to call setsid() or redirect file descriptors.
And in the future:
*) To avoid recursively calling ourself via DBus, when a later
patch causes g_app_info_launch() to indirect via the shell.
https://bugzilla.gnome.org/show_bug.cgi?id=606960
This signal contains the full path of the .desktop file, along with
the process id, which allows multiple interested components (like
GNOME Shell) to better know the state of the system (which processes
correspond to which .desktop files).

We want to be compatible with the following situation:
- there's no explicit default set in mimeapps.list
- we add support for a content type to a specific application, and that
list is empty
- the default should be picked from the system list, not overridden by
the user-added application.
So we make the default explicit in this case, by adding it to the
relevant section in mimeapps.list.
https://bugzilla.gnome.org/show_bug.cgi?id=637675
This commit also changes (maintaining compatibility) the way
user-specified default applications are stored (as in, those for which
g_app_info_set_as_default_for_type() has been called.
We now store the default application for a content type in a new group
in the mimeapps.list keyfile, and "Added Associations" tracks only the
applications that have been added by the user, following a
most-recently-used first order.
This is useful in GtkAppChooser-like widgets to pre-select the last used
application when constructing a widget.

Hiding the object/class structs in the source file makes this class not

The necessary review and integration work has not happened, and
we don't want to enshrine it in this unproven state.
It will be back when the world is ready for it.
Previously, the code only initialized the enumerator if the address
hadn't had cached addresses. But creating an enumerator cached the
addresses, so the second one failed to work.
Make the certificate and peer-certificate properties virtual, and add
peer-certificate-errors as well. Change the documentation on
peer-certificate to say that it's not set until after the handshake
succeeds (which means notify::peer-certificate can be used to tell
when a handshake has completed).
We were combining "allow un-notified closes" and "close without
notifying" into a single property, which meant that it was impossible
to "be liberal in what you accept and conservative in what you send".
Change require-close-notify to only be about the peer behavior, and
make our connections always close-notify properly when closing (while
noting that you can just close the base-io-stream directly if you want
to do an unclean close).
Trying to do this as a signal won't work well with either
GTlsCertificateDB (in which case looking up a certificate in the db is
a blocking/asynchronous act) or session resumption support (in which
case the certificate or lack thereof is part of the session definition
and so needs to be known immediately). Make the caller use
g_tls_connection_set_certificate() ahead of time (or when retrying)
instead.
Add a method to verify a certificate against a CA; this can be used
for apps that need to test against non-default CAs.
Also make the GTlsCertificate::issuer property virtual
This adds an extension point for TLS connections to gio, with a
gnutls-based implementation in glib-networking.

GProxyConnection is a class that was added for proxy support;
g_socket_client_connect() returns a GSocketConnection, but in some
cases (eg, encrypted SOCKS), GProxy might return a GIOStream that is
not a GSocketConnection. In that case, GSocketClient would wrap the
stream up in a GProxyConnection, which is a subclass of
GSocketConnection but uses the input/output streams of the wrapped
connection.
GTlsConnection is not a GSocketConnection, so it has the same problem,
so it will need the same treatment. Rename the class to
GTcpWrapperStream, and make it public, so people can extract the base
stream from it when necessary.
(This is not ideal and GSocketClient will need to be revisited as an
API at some point...)

When interfacing with APIs that expect unix-style async I/O, it is
useful to be able to tell in advance whether a read/write is going to
block. This adds new interfaces GPollableInputStream and
GPollableOutputStream that can be implemented by a GInputStream or
GOutputStream to add _is_readable/_is_writable, _create_source, and
_read_nonblocking/_write_nonblocking methods.
Also, implement for GUnixInput/OutputStream and
GSocketInput/OutputStream

g_cancellable_create_source() returns a GSource that triggers when its
corresponding GCancellable is cancelled. This can be used with
g_source_add_child_source() to add cancellability to a source.

cancellable handling, and also fix up its callback argument order to
be more normal.

Otherwise you break the fallback + recommended distinction for a content
type, as you end up adding support for a given content type to *all* of
the applications claiming to support the supertype.
This ways UIs can differentiate between them, and show them in different
section.
- a recommended app is an application that claims to support a content
type directly, not by a supertype derivation.
- a fallback app is an application that claims to support a supertype of
a given content type.
So that if we already have a list of emblems we know we want to add to
the icon, we can use e.g. a for loop to add them all, without picking
the first and looping from the second.

Removing an extension point is an API and ABI break. In particular, it
causes (older) gvfs versions to fail loading with a linkage error from
ld which in turn makes the desktop unusable.
So this reinstate the extension point and API provided by it, but
deprecates and does not use it. So no functionality is changed.

GSettings is now passing all of its tests on PowerPC.
Bug #630968 is closed.
GSettings relies on parts of the schema infromation remaining
unbyteswapped (the strinfo database, for example) while requiring other
parts to be in native order (the default value, constraints, etc.).
Lift the byteswapping into a place where we can do it selectively.
The test case was passing a guint16 to g_object_get() for a guint
property. That's invalid on all systems, although it works (more or
less) on little endian ones. On big endian it's a total no-go.
For GSettings.
Use the functionality introduced in the last commit to simplify our
notify dispatching and increase the safety of doing so (by ensuring that
the context is acquired in the current thread for the duration of the

Rewrite the GSettings tool.
Improvements/changes:
- simplify the code by performing common actions (like creating a
schema) in only one place instead of one per-command
- new features (list schemas, list keys, monitor multiple, etc)
- factor-out bash completion and implement in shellscript
- input validation: should never abort due to invalid inputs
Still to do:
- proper error checking for ranges/choices
- support for querying range/choice information
- bash completion support for enums
Closes bug #629289, possibly among others.
In its previous form, g_settings_list_schemas() was not useful as a tool
to prevent aborts due to using g_settings_new() with an invalid schema
name. This is because g_settings_list_scheams() also listed relocatable
schemas, and calling g_settings_new() for those would abort just the
same as if you called it for a non-existent schema.
Modify g_settings_list_schemas() so that it only returns schemas for
which it is safe to call g_settings_new(). Add another call for sake of
completeness: g_settings_list_relocatable_schemas().
Implement the second feature requested in the bug: silently ignore
override files that attempt to override schemas that are not currently
installed.
Also, support 'strictness' being optional for other errors when parsing
override files (ie: inability to open the file, unknown key name, parse
errors, out of range). We don't completely back out the file in this
case — as that is difficult with the current implementation — but just
ignore the override for the single key.
Implement the first of two features requested in the bug: when
encountering a broken .xml schema file, back out the changes in that
file and continue to parse other files.
This prevents a single broken .xml file from messing up GSettings for
everyone else.
Add a --strict option to get the old behaviour. Use this from the test
cases.
Move all the annotations over from gobject-introspection.
They will not be used directly by the introspection scanner for now,
instead they will be extracted by a script and updated manually
until introspection is properly integrated into the glib build
It doesn't really work right now because of a dbus-daemon(1) bug - see
the comment added in the TODO section of gdbusconnection.c. So revert
to old behavior. The downside is a lot of files in /tmp but right now
that's better than not being able to run tests in a loop.

Bug #629689.
These functions are meant to replace the read_until() flavour, with the
following improvements:
- consistency between the synchronous and asynchronous versions as to
if the separator character is read (it never is).
- support for using a nul byte as a separator character by way of
addition of a length parameter which allows stop_chars to be treated
as a byte array rather than a nul-terminated string.
The read_until() functions are not yet formally deprecated, but a note
has been added to the documentation warning not to use them as they will
be in the future.
This is bug #584284.
GSettings internally assumed that a change in key writability implied a
change in value. That may be true for some backends. Let those
backends deal with the situation for themselves.
The root problem is with GObject - for now, just work around it in
GDBus. Also include a test-case. See
