g_socket_client_connect_async() was always leaking its GCancellable,
and would also leak any GSocket that eventually failed to connect
after returning G_IO_ERROR_PENDING.
GSocket has a timeout flag now, but when using GSocketClient there was
no way to set the timeout until after connecting (or failing). Fix
that by adding a timeout property to GSocketClient.
Because g_simple_async_report_[g]error_in_idle() don't take a source tag
parameter, code that uses them can't currently use
g_simple_async_result_is_valid() (at least, not for the error case).
Bug 602417
The GClosure API is a bit funky (and badly documented), and requires
you to set a marshaller on the closure, and the marshaller has an
implicit 'this' argument, and the caller is reponsible for unsetting
the values after invoking the closure.
I've added some calls of the _with_closures variants to the
gdbus-names test now.
This prints all GDBusMethodInvocation API usage and is normally used
with the `incoming' option. Example:
# G_DBUS_DEBUG=incoming,return ./polkitd --replace

We use g_assert() instead of setting the GError because it is a
programming error if the GVariant contains invalid data - see commit
5e6f762d61 for where the last hole in
GVariant was closed.
So if we can trust GVariant to only contain valid data (ignoring the
case where unsafe API such as g_variant_new_from_data() is used), why
g_assert() at all with costly g_utf8_validate() checks? Because a) it
is relatively inexpensive; and b) it helps find bugs such as the one
fixed in commit 5e6f762d61.
If performance is a concern we can play games like introducing
environment variables or other machinery to avoid such "costly"
checks. I doubt it will ever be an issue.
Also replace two "Hmm" TODO item with a static assert - the code that
serializes a gdouble into the D-Bus wire format by treating it as a
guint64 is indeed correct - endianess needs to be taken into account
(see the D-Bus reference implementation for similar code). But we want
to make sure that we're indeed using an architecture/compiler where a
gdouble takes up 8 bytes - hence the assertion.

- Add a GCredentialsType enumeration that is used whenever exchanging

multiple native credential types. In particular, it allows
supporting OSes where the native credential evolves or even changes
over time.
- Add g_socket_get_credentials() method.

Note that things work exactly like libdbus, e.g. from the
dbus-launch(1) man page:
Whenever an autolaunch occurs, the application that had to start a
new bus will be in its own little world; it can effectively end up
starting a whole new session if it tries to use a lot of bus
services. This can be suboptimal or even totally broken, depending
on the app and what it tries to do.
[...]
You can always avoid autolaunch by manually setting
DBUS_SESSION_BUS_ADDRESS. Autolaunch happens because the default
address if none is set is "autolaunch:", so if any other address is
set there will be no autolaunch. You can however include autolaunch
in an explicit session bus address as a fallback, for example
DBUS_SESSION_BUS_ADDRESS="something:,autolaunch:" - in that case if
the first address doesn't work, processes will autolaunch. (The bus
address variable contains a comma-separated list of addresses to
try.)

The keyfile backend forms paths like this:
prefix + group_name + '/' + keyname
If the prefix is '/apps/yelp/' and the group name is '/' then this means
that we end up with a key name of (for example):
'/apps/yelp/' + '/' + '/' + 'font-adjustment'
= '/apps/yelp///font-adjustment'
which is obviously not a valid key name.
This patch rejects group names starting or ending with '/' or containing
'//' and also rejects keys containing '/'. This should make it
impossible for invalid keys to be formed.

Add support for extends='' and list-of='' tags to the <schema> element.
The attributes are parsed and some sanity-checking is done but currently
nothing happens as a result.
Add some tests.
There's a couple of places in GDBus where it's a programming error
(e.g. we'll assert or spew via e.g. g_warning()) to use the API on a
closed connection. This approach can never work since a
GDBusConnection can be closed at any point in time outside of
programmer control.
Just change the code to return a run-time error (e.g. return
G_IO_ERROR_CLOSED when sending messages, invoking methods) or silently
accept the request (e.g. exporting objects, registering for signals)
without doing anything.
Note that a GDBusConnection object is always useless after being
closed - e.g. there's no way to "reopen" a connection - the user will
have to create a new object and use that instead.

Neutralise and deprecate the --uninstall option in the schema compiler
and remove it from gsettings.m4.
Make the new default behaviour a compromise between the old default
behaviour and the previous --uninstall option:
- never return a failure code if no schema files are found
- issue a warning instead
- remove the gschemas.compiled file if it exists
We only ever do the enum mapping for the property binding in the case
that a GParamSpecEnum exists and in that case the class is already
referenced by the GParamSpec. Use peek instead of ref/unref and add a
clarifying note.
Fix a bug where the type from g_variant_get_type() was used after
freeing the variant. This works for base types (since they are cached
and live forever) but not for arrays (where the bug was first seen).
Hold the GSettingsKeyInfo as part of the binding structure to save work
on each get/set. Use our copy of this structure to call the internal
get/set APIs. Give more descriptive error messages in the case of
invalid data on sets and retry using the translated default then schema
default value in case of failure to map on reads.
If we know the expected interface (e.g. :g-interface-info is set),
then we always warned when calling a method on a different
interface. Don't do that, there's no way the expected interface can
know anything about this method.

Either child_watch_source or timeout_source will already have been
destroyed after we finish the loop, and it's not safe to call
g_source_destroy() on it a second time unless we're still holding a
ref on it.
When disposing a GSocketConnection, don't explicitly close the
underlying GSocket. The GSocket will close itself if it gets
destroyed, and if it doesn't get destroyed, that presumably means the
app still wants to use it. Eg, this lets you use GSocketClient to
create a GSocketConnection, and then take the GSocket and destroy the
GSocketConnection.

This is a minimal patch-out of the galias functionality. We will do a
release like this so that we can easily back it out if there are
reported problems.
A more substantial cleanup (mostly removing #includes from every file)
will follow if there are no issues.
Having this tool in GLib is a bad idea for a number of reasons:
- experience has shown that the simple file format was a bad idea
- the tool is currently implemented with a hack that would require a
dependency inversion to solve (the tool needs to depend on Python
GVariant bindings)
- the tool itself is unmaintained
It will be moved to the GConf git repository so people can continue to
use it for the purpose of converting GConf schemas.
When no path is provided for the schema, we have call
g_settings_new() instead of g_settings_new_with_path()
passing a NULL path.
This was crashing the tool on start since an assertion was
recently added to g_settings_new_with_path() to refuse NULL.
We can't search for a larger needle inside of a smaller haystack, and
unsigned integer subtraction tends to result in very large numbers
rather than small ones.
Add a check for this case and abort out immediately.
Also add a test case (lifted directly from the docs) that demonstrates
the problem.

While we are already propagating the error to the user via the
GDBusConnection::disconnected signal (because the only safe thing is
to disconnect the other peer), changes are the user is simply not
listening to this signal.
This should never ever happen unless there's a bug in the
serializaer/deserializer so it's fine to complain via g_warning()
here.
Bug 621838, see

The GType for a GVariant is now a fundamental GType instead of a boxed
one so use the right marshaller.

When asynchronously acquiring the DBus connection, assume a reference to
the proxy object, to avoid destroying it in the middle of the operation.
See https://bugzilla.gnome.org/show_bug.cgi?id=621905
Like how we're handling activation, use GVariant for timestamps. To
avoid polluting the GtkApplication API with GVariants, we rename the
GApplication signals to "quit-with-data" and "action-with-data".
GtkApplication will then wrap those as just "quit" and "action".

Allow constructing a GDBusProxy for well-known names as discussed here
http://mail.gnome.org/archives/gtk-devel-list/2009-October/msg00075.html
including test cases.
Make it possible to create a GDBusProxy for a GBusType instead of a
GDBusConnection. This requires G_BUS_TYPE_NONE so add that too.
Nuke g_bus_watch_proxy() since one can now more or less use GDBusProxy
for this.
Port gdbus-example-watch-proxy to this new API and include this
example in the GDBusProxy doc page.
Also nuke the GType parameter from the GDBusProxy constructors as
requested here: https://bugzilla.gnome.org/show_bug.cgi?id=621229
Also update the porting guide and other API docs for this change.
Also fix a bug in the signal dispatching code so each subscriber only
get notified once, not N times, for the same signal. Also add a test
case for this.

The name buffer_availabile was kinda confusing, so its been renamed
to buffer_data_size() to match buffer_data().
Also I added a comment to buffer_ensure_space because its behaviour
wasn't obvious.
When the converter fills the whole buffer without reading all input,
we need to enlarge the buffer. Otherwise we get an assertion failure
for `outbuf_size > 0' in g_converter_convert.

gvdb just dropped the ability to have a separate "options" field. We
now store the options into a GVariant along with the default value.
For now, we use a small shim in GSettingsSchema in order not to touch
too much code. A more complete rewrite will follow.
This represents a change to the schema file format with another likely
to follow. glib-compile-schemas needs to be re-run after installing
this change.

Create a function run_with_application that both ensures the
app is running exactly while the test is running, which most
of the tests use. We start it beforehand, and kill it after.
This avoids having any interdependence between the tests (and
there definitely was before, because we didn't wait for
the process to actually terminate after a kill() call).
Also, open a pipe between the two, and have the child app
monitor that pipe. If it gets closed (e.g. because the parent
died), the child exits. This is the most reliable way to
avoid stale children; before, if we failed an assertion, the
parent would abort, and not run kill().

There was a slight race where we ended up calling into user code if
the user managed to unregister an object (or subtree) in the window
between
- processing the remote call on the worker thread; and
- continuing handling it on the user code thread (via an idle handler)
This patch fixes the problem.

Fix proxy construction for objects with no properties in the case
where G_DBUS_PROXY_FLAGS_DO_NOT_LOAD_PROPERTIES isn't set.
The unfortunate side-effect here is that GDBusProxy can no longer be
used to test for "object existence", e.g. creating a GDBusProxy for
any path and interface will not fail. But that's not really a big
deal, if apps rely on that they are doing something very wrong.

This adds a GApplication object to GIO, which is the core of
an application support class, supporting
- uniqueness
- exporting actions (simple scripting)
- standard actions (quit, activate)
The implementation for Linux uses D-Bus, takes a name on the
session bus, and exports a org.gtk.Application interface.
Implementations for Win32 and OS X are still missing.
The GSettings schema compiler was accepting any string as a path. It is
probably quite a common mistake to suspect that '/apps/foo' is a valid
path name when this will cause all sorts of trouble later. Check for
this case and report the error.
Since #include <gsettingsbackend.h> is a perfectly valid thing for
applications to do, and since we want to include gio headers from
gsettingsbackend.h, we need to effectively disable the #error we would
get from those headers (because we're not coming via gio.h).
We don't want to #include <gio/gio.h> here because this would cause
needless rebuilding of GSettingsBackend, GSettings,
GDelayedSettingsBackend, etc... every time someone changed anything in
any public header.
add GSimplePermission, a trivial const implementation of GPermission
can-request and can-release are always false for this implementation and
the value of 'allowed' is decided at construction.
Add GObject introspection annotations so that the length parameter is
correctly detected for g_variant_new_strv(), g_variant_get_strv() and
g_variant_dup_strv(). Also specify that it can be a NULL pointer in
g_variant_get_strv() and g_variant_dup_strv().
For g_settings_set_strv(), detect that a NULL value is allowed, meaning
empty array.

Length of the array is redundant since it's NULL-terminated. This is not
consistent with many GLib and GTK+ functions, and adds complexity with
no real gain, while these convenience functions should be kept simple.
Closes bug #620312
This allows the caller to specify the reply type that they are expecting
for this call. If the reply comes back with the wrong type, GDBus will
generate an appropriate error internally.
- add a GVariantType * argument to g_dbus_connection_call() and
_call_sync().
- move the internal API for computing message types from introspection
data to be based on GVariantType instead of strings. Update users
of this code.
- have GDBusProxy pass this calculated GVariantType into
g_dbus_connection_call(). Remove the checks done in GDBusProxy.
- Update other users of the code (test cases, gdbus-tool, GSettings
tool, etc). In some cases, remove redundant checks; in some other
cases, we are fixing bugs because no checking was done where it
should have been.
Closes bug #619391.
Ryan pointed out on IRC that we didn't do anything here. Looking at
the code, it's painfully obvious that we should be returning an error
here since a comment already says that we've exhausted all possible

- Fix various #include issues
- Change #error to #warning for the EXTERNAL authentication mechanism.
It is not clear if this should work on Win32 at all.
- Call close() before unlink() for the SHA1 keyring
- Change #error to #warning so we don't forget to do
permission checking of the .dbus-keyrings directory
- Use Win32 SID for the SHA1 auth mech
- Apparently we can't use word 'interface' as an identifier
- Implement a _g_dbus_win32_get_user_sid() function. For now it's
private. Don't know if it should be public somewhere. Maybe in
a future GCredentials support for Win32? I don't know.
- GFileDescriptorBased is not available on Win32. So avoid using
it in GLocalFile stuff. Now, Win32 still uses GLocalFile + friends
(which works with file descriptors) so expose a private function
to get the fd for an OutputStream so things still work.
- Fixup gio.symbols
- Fixup tests/gdbus-peer.c so it builds
With this, at least things compile and the gdbus-peer.exe test case
passes. Which is a great start. I've tested this by cross-compiling on
a x86_64 Fedora 13 host using mingw32 and running the code on a 32-bit
Windows 7 box.

If --uninstall is given then don't give an error if the schema directory
is empty. Instead, erase the gschemas.compiled file, if it exists.
This is the right thing to do in the 'make uninstall' rule, where the
schema directory could very well be left empty as a result.
Modify gsettings.m4 to use this option.
The test was assuming that g_timeout_add() waited for at least the amount of
time given to it before running the function. This is not the case -- the
function can be run as much as 1ms early. Make the lower time bound asserted
in the test more permissive to account for this.
- hold a lock while accessing the tree of delayed values
- use weak reference counts with the owner object to avoid doing
g_object_notify on a dead object
- dispatch the "has-unapplied" notify to the proper main context
This commit fixes up a few race conditions in the GSettingsBackend, mostly with
respect to change notifications occuring at the same time as the last reference
count on a GSettings is dropped. With GDBus feeding us our incoming signals in
a separate thread, this is something that could easily happen.
