Turns out that GDBusWorker will issue callbacks (in its own thread)
even after g_dbus_worker_stop() has been called. This would rarely
happen (and unreffing a connection is even rarer) so only saw this bug
occasionally when running the gdbus-connection test case in a loop.
Fix up this issue by maintaining a set of GDBusConnection objects that
are currently "alive" and do nothing in the callbacks if the passed
user_data pointer is not in this set.
Also attempted to fix up a race condition with
_g_object_wait_for_single_ref_do() and its use of GObject toggle
references - for now, just resort to busy waiting, thereby
sidestepping the toggle reference mess altogether.

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.
The root problem is with GObject - for now, just work around it in
GDBus. Also include a test-case. See
https://bugzilla.gnome.org/show_bug.cgi?id=627724
for more information.

Ryan pointed out that it's safe to do this because we have the
G_DBUS_SEND_MESSAGE_FLAGS_PRESERVE_SERIAL flag and that it simplifies
how filter functions work.

Otherwise things probably won't work in a garbage-collected world
(consider the trivial GC that never collects garbage).
This commit breaks GDBusServer ABI. No known released software is
using this code.

Rework filter functions as per
https://bugzilla.gnome.org/show_bug.cgi?id=624546#c8
This commit breaks ABI. However, this ABI break affects only
applications using filter functions. The only known user of is dconf.

Don't actually use this yet as that will require a couple of
modifications to the filter function signature. This is part of the
bug-fix for

Bug #627187.
Add GZlibCompressor:file-info property. If it contains a non-NULL
GFileInfo, and the compressor is in GZIP mode, the filename and
modification time from the file info are written to the GZIP header
in the output data.
Add GZlibDeompressor:file-info property. If the decompressor is in GZIP
mode, and the GZIP data contains a GZIP header, the filename and
modification time are read from it, stored in a GFileInfo, and the
file-info property is notified.
Bug #617691.
If sending a lot of data and/or the other peer is not reading it, then
socket buffers can overflow. This is communicated from the kernel by
returning EAGAIN. In GIO, it is modelled by g_output_stream_write()
and g_socket_send_message() returning G_IO_ERROR_WOULD_BLOCK.
It is also problematic that that we're using synchronous IO in the
shared GDBus IO thread. It means that one GDBusConnection can lock up
others.
It turns out that by porting from g_output_stream_write() to
g_output_stream_write_async() we fix the EAGAIN issue. For GSocket, we
still need to handle things manually (by creating a GSource) as
g_socket_send_message() is used.
We check the new behavior in Michael's producer/consumer test case (at
/gdbus/overflow in gdbus-peer.c) added in the last commit.
Also add a test case that sends and receives a 20 MiB message.
Also add a new `transport' G_DBUS_DEBUG option so it is easy to
inspect partial writes:
$ G_DBUS_DEBUG=transport ./gdbus-connection -p /gdbus/connection/large_message

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.
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.
The D-Bus spec mentions exactly what header fields are required for
various message types. Add tests for this as well.
Also disallow empty interfaces for signals since the D-Bus spec says
this is Verboten already.

Don't do too much work in the finalizer - in particular, there's no
need to send RemoveMatch() messages to the bus daemon since we're
going to sever the connection and the bus will garbage collect
anyway. In this case it crashed the process.
Also add a test case that checks that the appropriate GDestroyNotify
callbacks are called when unreffing a connection with either 1)
exported objects; 2) signal subscriptions or 3) filter functions
.. yes, ideally apps would unregister such callbacks before giving up
their ref but that's not how things work :-)

- Make GCredentials instance and class structures private so it can't
be subclassed and we don't have to worry about ABI compat
issues. This also allows us to get rid of the GCredentialsPrivate
struct.
- Add a GCredentialsType enumeration that is used whenever exchanging
pointers with the user. This allows us to support OSes with
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.
- Add tests for g_socket_get_credentials(). Right now this is in the
GDBus peer-to-peer test case but we can change that later.
- Move GTcpConnection into a separate gtk-doc page as was already
half-done with GUnixConnection. Also finish the GUnixConnection
move and ensure send_credentials() and receive_credentials()
methods are in the docs. Also nuke comment about GTcpConnection
being empty compared to its superclass.

This allows sending and receiving D-Bus messages with instances of the
'h' D-Bus type. Unlike libdbus-1's dbus_message_iter_get_basic()
method, g_variant_get_handle() does not return a duplicated unix file
descriptor (that must be closed with close(2)) - instead, it returns
an index that can be used to get/dup the file descriptor from a
GUnixFDList object that can be obtained from the GDBusMessage object.

This is currently unused but might be useful in the future. For

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().

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.
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.

The test was assuming that g_timeout_add() waited for at least the amount of

in the test more permissive to account for this.

This is to match g_dbus_connection_new(). This extension allows us to
extend GDBusAuthObserver to also be used in client-side authentication
in the future (right now it's only used on the server-side).
This is needed to e.g. allow encoding maybe types (once we add
G_DBUS_CAPABILITY_FLAGS_MAYBE_TYPES) if, and only if, that capability
has been negotiated with the peer (via authentication).
Also make the gdbus-example-server include some example

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.
These are included wholesale in the docs, and the copyright
headers make them even more overwhelming. Plus, we don't have
copyright headers on examples anywhere else.
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).
Things compile and the test-suite passes. Still need to hook up
gio.symbols and docs. There are still a bunch of TODOs left in the
sources that needs to be addressed.

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

Gschema-compile uses glob which is available on Unix only. Thus can't

To avoid an Automake error, comment out the SOURCES and LDADD of

TEST_PROGS.
Can't use a Makefile.am target called foo_PROGRAMS for random files

Correspond to GUnixInputStream and GUnixOutputStream. No true async
support though. But that is how the Win32 API is, for files not
explicitly opened for so-called overlapped IO.
The API to create these streams takes Win32 HANDLEs. Not file
descriptors, because file descriptors are specific to the C library
used. The user code and GLib might be using different C libraries.
Also add a test program for the new classes, and a gio-windows-2.0.pc
file.
It turns out that the way this worked did not work out for the current
main usecase (gedit) due to issues with how this is best integrated
with GtkTextView. So, in order to not have to support an unused non-ideal
API forever we remove this before its been in a stable release.
The basic feature seems to have some utility though, so we hope for it
to eventually return in a better form.

Currently, to implement cancellability correctly, all synchronous

checks inside GSocket instead, and we don't particularly want to
encourage people to use the APIs non-cancellably, move the

In particular, targets with weight 0 should be very UNlikely to be

update.
glib/garray.c, glib/gbase64.c: fix signed/unsigned pointer casts
gio/xdgmime/xdgmimeglob.c: remove unused variable
gio/tests/live-g-file.c: fix printf args on x86_64
tests/Makefile.am, tests/regex-test.c: remove redundant -DENABLE_REGEX
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.
Part of #548466.
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.

Bug 568394 – dropping the last reference to a stream filter closes the
base stream
* gfilterinputstream.h:
* gfilterinputstream.c: add "close-base-stream" property and only
close the base stream if it is true. issue async close callbacks from
correct source object.
* gfilteroutputstream.h:
* gfilteroutputstream.c: add a "close-base-stream" property and only
close the base stream if it is true. issue async close callbacks from
correct source object.
* gbufferedoutputstream: check g_filter_output_stream_get_close_base()
before closing the base stream. fix invalid source tag comparison in
close_async (was comparing to flush_async).
* ../docs/reference/gio/gio-sections.txt:
* gio.symbols: add
g_filter_{in,out}put_stream_{g,s}et_close_base_stream
* tests/filter-streams.c: new test cases

Bug 547481 – g_data_input_stream_read_line behaves not as stated in
the docs
* gdatainputstream.c (g_data_input_stream_read_line): Behave as
documented and include the line end in the returned string.
Pointed out by Paul Pogonyshev.
* tests/data-input-stream.c: Fix the read_line test to test the
documented behaviour.

available
* gio/gbufferedinputstream.c (g_buffered_input_stream_read_byte): Fix
handling of buffered content. Patch by Philip Withnall
* gio/tests/buffered-input-stream.c: Add a testcase for this bug.

Bug 509446 - portable blocking gio cancellation
* gcancellable.c (g_cancellable_make_pollfd): New method to make a
GPollFD for a cancellable (which is slightly more complicated on
Windows than Unix).
* gunixinputstream.c (g_unix_input_stream_read):
* gunixoutputstream.c (g_unix_output_stream_write): Use
g_cancellable_make_pollfd() and g_poll() rather than using poll()
directly.
* tests/unix-streams.c: test of GUnixInputStream,
GUnixOutputStream, and GCancellable.

* tests/live-g-file.c:
Include live-g-file in standard set of tests, making a temporary
directory in source structure.
Clean target directory before the tests (write mode only)

2008-02-21 Alexander Larsson <alexl@redhat.com>
* gfile.[ch]:
* gio.symbols:
Add new g_file_has_prefix that does the same as g_file_contains_file.
Deprecate g_file_contains_file and add a macro that converts
it to g_file_has_prefix.
The reason for this change is that the contains_file() name seems to
imply that this does more work than what it does, but its really only
a name match (from #517086)
* gdummyfile.c:
* glocalfile.c:
* tests/g-file.c:
Update to match the above change.

Canonicalize paths that start with more than
two slashes.

Test the above
