-Added glib/ghmac.h to the list of files to copy during the "install" stage
-Cleaned up a bit (glib-2.0->glib-$(ApiVersion), where $(ApiVersion) is
2.0)
This makes g_date_time_format() react to LC_TIME, which is
what people expect.
Translators: this change means that the GDateTime strings
are only used when the C library does not already provide
suitable translated strings for these (month names, etc).
* Update documentation to note that GCancellable can be used
concurrently by multiple operations.
* Add documentation to g_cancellable_reset that behavior is
undefined if called from within cancelled handler.
* Add test for multiple concurrent operations using the same
cancellable.

Destroying a GDBusProxy in a thread used to race with NameOwnerChanged
being delivered to the main context's thread (GNOME #651133).
Also, g_dbus_proxy_call_sync in a thread would race with NameOwnerChanged
being delivered to the main context's thread and rewriting the name_owner
(GNOME #656039).

This changes the meaning of "properties_lock" from "lock for D-Bus
properties" to "lock for GObject properties".
The most common problem, and the only one I've reproduced in a regression
test, is name_owner, which can be updated by the thread that owns
the GDBusProxy's main context (i.e. the thread-default main context of
the thread that constructed it) at the same time that a blocking call
is made. When a GDBusProxy is constructed in a thread-pool thread for
short-term use, the main context will typically be the global default
main context (which is actively running in the main thread!), making
this extremely problematic.
The interface info is perhaps a theoretical concern - one thread could
conceivably set it at the same time that another thread uses it, but only
in relatively pathological situations. The current API for this does have
the problem that it returns a borrowed ref, but interface info is
hopefully permanent anyway.
The default timeout is probably only a theoretical concern - it's just an
int, so writes are indivisible, and there's no worry about whether
something has been freed - but to be safe, let's hold the lock for that
too.

This removes the need for async_init_get_name_owner_cb to cope with being
called without a real GAsyncResult, and will simplify the addition of
correct thread-locking.
In async_init_data_set_name_owner, use the name_owner parameter instead
of the corresponding member of GDBusProxyPrivate, partly to reduce
pointer-chasing but mainly to avoid needing to hold the lock.

These ought to have thread-locking, and having it in the accessor seems
better than duplicating it here.

If you run:
( cd gio/tests && G_DBUS_DEBUG=all ./gdbus-proxy-well-known-name )
you can see that in the case where the name com.example.TestService isn't
owned yet, the GDBusProxy calls GetAll() with no destination, resulting
in an error reply from the peer (the dbus-daemon itself). That's clearly
not right!
However, if priv->name is NULL, that indicates the special case where we
really do want to talk directly to a peer, instead of via the bus daemon
(most likely to be used on peer-to-peer connections); in that special
case, do call GetAll().

This is needed because the proxy may need to update its internal state
which a signal handler connected to the manager may rely on.

Posix allows for open(2) to fail with errno = EINTR.
Normal this isn't seen when opening files. However in some case we are
opening a fifo for write which will block until another process opens it
for read. If a signal is received while blocked, open(2) fails with
errno = EINTR.

At the same time, also add g_mkdtemp_full and g_dir_make_tmp
variants. The patch also unifies the unique-name-generating
code for all variants of mkstemp and mkdtemp and adds tests
for the new functions.

This implements g_hmac_xxx() functionality using the standard checksum
functions supported by glib.
HMAC is a secure way to hash a key and a password. Many other

The implementation of GValue is not public or documented. When
allocated on the stack, initializing a GValue is usually done as
documented with:
GValue value = { 0, };
There is lot code around (including WebKit) that added all the missing
fields, resulting in this ugly and non-obvious:
GValue value = { 0, { { 0 } } };
However, this doesn't play nice with -Wmissing-field-initializers for
example. Thus, G_VALUE_INIT.

This avoids calling g_variant_unref and g_free on uninitialized memory
if PropertiesChanged is received in the creating thread's thread-default
main context's thread, at the same time as releasing the last ref in
another thread. This would result in "goto out" before the variables
freed after that label had been initialized to NULL.
