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.)

Without this guarantee, peer-to-peer connections are not very
useful. However, with this guarantee it's possible to export objects
in a handler for the GDBusServer::new-connection signal.
There are two caveats with this patch
- it won't work on message bus connections
- we don't queue up messages to be written
that can be addresses later if needed.

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.
GBinding is a simple, opaque object that represents a binding between a
property on a GObject instance (source) and property on another GObject
instance (target).

g_object_notify_by_pspec() will emit the "notify" signal on the given
pspec, short-circuiting the hash table lookup needed by
g_object_notify(). The suggested and documented way of using
g_object_notify_by_pspec() is similar to the way of emitting signals
with their ID.
Emission tests (with no handler attached to the notify signal) show a
10-15% speedup over using g_object_notify().

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.
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.
This adds static markers for dtrace, which are also usable
by systemtap. Additionally it adds a tapset for systemtap
that makes it easier to use the static markers.
These are enabled by default.
This initial set of probes is rather limited:
* allocation and free using g_malloc & co
* allocation and free using g_slice
* gquark name tracking (useful for converting quarks to strings in probes)
Notes on naming:
Its traditional with dtrace to use probe names with dashes as
delimiter (slice-alloc). Since dashes are not usable in identifiers
the C code uses double underscores (slice__alloc) which is converted
to dashes in the UI. We follow this for the shared lowlevel probe
names.
Additionally dtrace supports putting a "provider" part in the probe
names which is essentially a namespacing thing. On systemtap this
field is currently ignored (but may be implemented in the future), but
this is not really a problem since in systemtap the probes are
specified by combining the solib file and the marker name, so there
can't really be name conflicts.
For the systemtap tapset highlevel probes we instead use names that
are systemtapish with single dashes as separators.

Fixup for commit 133f66538d which
duplicated the contents of most of the migration documentation by
splitting it out into separate files but keeping the original file
intact (with a rename).
This removes the duplicated content from the renamed file.
This uncovered a bug in name watching if the name wasn't activatable.
Also provoked the need for on_connection variants of g_bus_watch_name
(added g_bus_watch_proxy's variant as well).
This makes it possible to use the cached properties mechanism even if
constructing the proxy with the DO_NOT_LOAD_PROPERTIES flag.
This is useful for cases where you obtain the and track object
properties out-of-band. For example, in udisks, the plan is to have
something like this
Manager.GetObjects (out ao paths, out aa{sa{sv}} all_properties);
Manager.ObjectAdded (o path, a{sa{sv}} all_properties);
Manager.ObjectChanged (o path, a{sa{sv}} all_properties);
Manager.ObjectRemoved (o path, a{sa{sv}} all_properties);
E.g. the first GetObjects() call will return *all* data about *all*
exported objects. Further, this way a client will only need to listen
these three signals (three AddMatch) on the Manager object and it will
never need to do GetAll() etc (e.g. can use DO_NOT_LOAD_PROPERTIES).
(Of course this only works if the client is interested in all
objects... while this is true for udisks it is generally not true for
other D-Bus services).
Also use expected_interface to check for programming errors.
Lots of people been suggesting this. We still use MethodInvocation /
method_invocation for handling incoming method calls so use call()
instead of invoke_method() helps to separate the client and server
facilities. Which is a good thing(tm).
There are apparently two incompatible ways of naming abstract sockets:
pad the sockaddr with 0s and use the entire thing as the name, or else
don't, and just pass a shorter length value to the relevant functions.
We previously only supported the former method. Add support for the
latter.
Also correctly handle "anonymous" unix sockaddrs (eg, the client side
of a connection, or a socketpair() socket), and add unix domain socket
support to the socket-client and socket-server test programs to make
sure this all works.
https://bugzilla.gnome.org/show_bug.cgi?id=615960
Merge GVariant variable arguments support and put it under tests.
Also, remove the hack of the test case directly '#include'ing .c files
from glib/. Instead, create a non-installed gvariant-internal.h that
the tests can include and make the symbols in it visible on the symbol
table of the shared library. These symbols (as they are present in no
installed header files) are not part of the API of GLib.
Increase test coverage in a few other areas.
Add support for a mutex lock that consumes only one bit of storage
inside of an integer on systems that support futexes. Futex is emulated
(at a higher cost) on systems that don't have it -- but only in the
contended case.
We now allow g_thread_init(NULL) to be called after other glib calls (with
some minor limitations). This is mainly a documentation change as this
really was already possible.
We also allow g_thread_init() to be called multiple times. Only the
first call actually initializes the threading system, further calls
are ignored (but print a warning if the argument is not NULL).

Previous code used g_mkstemp(). But when using
G_FILE_CREATE_REPLACE_DESTINATION, no attempt was made to ensure proper
mode and flags of the created temporary file. The visible issue was that
the file was always created with mode 0600 as opposed to using 0666.
(The invisible issue was that O_RDWR was used instead of O_WRONLY.)
This function exposes more variables than g_mkstemp() and therefor
allows more flexibility when creating temporary files.
The intended use is gio's code for g_file_replace() (see next patch)
This patch only adds the function. The function is a NOP.
See the API documentation for a rationale.
Part of: Bug 591388 - number of GCancellables available is too limited
For details, see bug 587482. The new api:
- Provide new _with_operation() variants of all unmount and eject methods
- Add GMountOperation::show-processes signal
- this can be used to show processes blocking an unmount operation
- Deprecate all unmount and eject methods
- Add g_drive_can_start_degraded() method
- this is to avoid auto-starting degraded drives
- Make g_drive_stop() resp. g_file_stop_mountable() take a GMountOperation
- these ops were recently added and not yet public API so it's fine
to change how they work
- Provide a way to poll mountable files, e.g. g_file_poll_mountable()
- Add some missing file attributes for mountable files
- G_FILE_ATTRIBUTE_MOUNTABLE_UNIX_DEVICE_FILE
- needed for the GDU Nautilus extensions to format a volume
- G_FILE_ATTRIBUTE_MOUNTABLE_CAN_START_DEGRADED:
- mimics g_drive_can_start_degraded()
- G_FILE_ATTRIBUTE_MOUNTABLE_CAN_POLL:
- mimics g_drive_can_poll_for_media()
- G_FILE_ATTRIBUTE_MOUNTABLE_IS_MEDIA_CHECK_AUTOMATIC
- mimics g_drive_is_media_check_automatic()
Add API for starting/stopping drives. This new API will enable
GVolumeMonitor and GVfs implementations to add support for the
following features
1. Powering down external hard disk enclosures / drives
2. Starting/stopping multi-disk devices (such as RAID/btrfs/ZFS)
3. Connecting/disconnecting iSCSI devices
4. Reacting to the user pressing e.g. the "remove drive" button on
a IBM/Lenovo Ultrabay: http://www.thinkwiki.org/wiki/Ultrabay
See the bug for the corresponding GVfs and Nautilus changes.
The whole protocol name thing is pretty weird. The getprotobyname functions
seem to only specify one mapping for name <-> ids, so all families/types
must use the same values. Plus the values used for the protocols are
standardized by IANA, so are always the same.
So, we drop using names for protocols, intead introducing an enum with
a few commonly availible and used protocols.
Higher-level wrappers around GResolver. GSocketConnectable provides an
interface for synchronously or asynchronously iterating multiple
socket addresses, with GNetworkAddress and GNetworkService providing
interfaces based on hostname and SRV record resolution.

GResolver provides asynchronous (and synchronous-but-cancellable) APIs
for resolving hostnames, reverse-resolving IP addresses back to
hostnames, and resolving SRV records. Part of #548466.
Types and methods for dealing with IPv4 and IPv6 addresses (and UNIX
domain socket addresses under UNIX). This does not include code for

There are race conditions when connecting and disconnecting from the
