Using the generic marshaller has drawbacks beyond performance. One such
drawback is that it breaks the stack unwinding from the Linux kernel due
to having unsufficient data to walk past ffi_call_unixt64. That means that
performance profiling by application developers looks grouped among
seemingly unrelated code paths.

We already have the GType with which the GValue should be initialized,
so requiring an initialized GValue is not really necessary, and it
actually complicates code that wraps GObject, by requiring the retrieval
of the GParamSpec in order to get the property type. Additionally, it
introduces a mostly unnecessary g_value_reset().
We already changed g_object_getv() to allow passing uninitialized
GValues, but this fell through the cracks.

Mixing atomic and non-atomic reads trips TSAN, so let's change the

Currently, g_object_ref() and g_object_ref_sink() return a
gpointer which can mask issues when assigning to fields or
returning from a function.
To help catch these type of programming errors, we can propagate
the type of the parameter through the function call on GCC
using the typeof() C language extension.
This will cause offending code to have a warning, but will
continue to be source and binary compatible.
This is only enabled when GLIB_VERSION_MAX_ALLOWED is 2.56 or greater.

g_object_newv uses a GParameter as argument. Since GParameter

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
The C spec leaves conditional evaluation inside a macro expansion as
undefined behaviour. This means we cannot use constructs like:
GOBJECT_IF_DEBUG(OBJECTS, {
...
#ifdef BLAH
...
#endif
...});
Because compilers are entirely justified to ignore the conditional, or,
like in the case of MSVC, error out.

historically, DEBUG_CODE(gtype.c) and IF_DEBUG(gobject.c, gsignal.c)
macros are used to support debugging messages about object bookkeeping
and signal emission.
DEBUG_CODE has never been used in gtype.c. IF_DEBUG, when used, must be
accompanied by an extra #ifdef G_ENABLE_DEBUG. this is cumbersome.
this patch add a new macro GOBJECT_IF_DEBUG based on DEBUG_CODE as
a replacement for both DEBUG_CODE and IF_DEBUG.

Add various (nullable) and (optional) annotations which were missing

Secondly, add various (not nullable) annotations as needed by the new
default in gobject-introspection of marking gpointers as (nullable). See
https://bugzilla.gnome.org/show_bug.cgi?id=729660.
This includes adding some stub documentation comments for the
assertion macro error functions, which weren’t previously documented.
The new comments are purely to allow for annotations, and hence are
marked as (skip) to prevent the symbols appearing in the GIR file.
https://bugzilla.gnome.org/show_bug.cgi?id=719966
Keeping these enabled causes too many people to file
bugs against gobject, and not enough people to send
patches to port away from deprecated properties.
Practically no caller of these functions require atomic behaviour,
but the atomics are much slower than normal operations, which makes
it desirable to get rid of them. We have not done this before because
that would be a break of the ABI.
However, I recently looked into this and it seems that even if the
atomics *are* used for g_clear_* it is not ever safe to use this. The
atomics protects two threads that are racing to free a global/shared
object from freeing the object twice. However, any *user* of the global
object have no protection from the object being freed while in use,
because there is no paired operation the reads and refs the object
as an atomic unit (nor can such an operation be implemented using
purely atomic ops).
So, since nothing could safely have used the atomic aspects of these
functions I consider it acceptable to just remove it.

Add a flag to prevent the automatic emission of the "notify" signal

many cases where it is needed.

Although returning NULL from constructor is strongly discouraged, some
old libraries need to keep doing it for ABI-compatibility reasons.

We have turned up enough cases of this being done (including GTK API
allowing apps to do this to GtkSettings well after it has been
instantiated) that it is clear that we cannot really break this feature
while claiming to be backwards compatible.
For that reason, it becomes a warning rather than a critical (ie: it is
still well-defined behaviour, but you are discouraged from doing it).
The intention is to keep this feature for at least the next while.
A given GObjectClass will be able to avoid using GParamSpec pool for as
long as you don't install properties after init. If you do that, you
will get a warning and we will devolve to using GParamSpecPool.

GObject has previously allowed installing properties after class_init
has finished running. This means that you could install some of your
own properties on G_TYPE_OBJECT, for example, although they wouldn't

because it broke the shell. Instead of reverting, we should have used a
critical, so do that now.

Back in the far-off twentieth century, it was normal on unix
workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027
APOSTROPHE to be drawn as "’". This led to the convention of using
them as poor-man's ‛smart quotes’ in ASCII-only text.
However, "'" is now universally drawn as a vertical line, and "`" at a
45-degree angle, making them an `odd couple' when used together.
Unfortunately, there are lots of very old strings in glib, and also
lots of new strings in which people have kept up the old tradition,
perhaps entirely unaware that it used to not look stupid.
Fix this by just using 'dumb quotes' everywhere.

There is some code in the wild (like in gnome-session) that does this
from its custom _constructor() implementation:
{
GObject *obj;
obj = ((chain up));
if (!object_is_viable (obj))
{
g_object_unref (obj);
return NULL;
}
else
return obj;
}
This has never been a valid use of GObject and this code has always
caused memory to be leaked[1] by growing the construction_objects list.
The ability to legitimately return NULL from a constructor was exactly
the reason that we created GInitable, in fact.
That doesn't change the fact that the g_object_new() rewrite will crash
in this case, so instead of doing that, let's emit a critical and avoid
the crash. This will allow people to upgrade their GLib without also
upgrading their gnome-session. Meanwhile, people can fix their broken
code.
[1] not in the strictest sense of the word, because it's still reachable
Make a number of improvements to g_object_new():
- instead of looking up the GParamSpec for the named property once in
g_object_new() (in order to collect) and then again in g_object_newv
(when actually setting the property), g_object_new_internal() is a
new function that takes the GParamSpec on the interface to avoid the
second lookup
- in the case that ->constructor() is not set, we need not waste time
creating an array of GObjectConstructParam to pass in. Just directly
iterate the list of parameters, calling set_property() on each.
- instead of playing with linked lists to keep track of the construct
properties, realise that the number of construct properties that we
will set is exactly equal to the length of the construct_properties
list on GObjectClass and the only thing that may change is where the
value comes from (in the case that it was passed in)
This assumption was already implicit in the existing code and can be
seen from the sizing of the array used to hold the construct
properties, but it wasn't taken advantage of to make things simpler.
- instead of allocating and filling a separate array of the
non-construct properties just re-iterate the passed-in list and set
all properties that were not marked G_PARAM_CONSTRUCT (since the ones
that were construct params were already used during construction)
- use the new g_param_spec_get_default_value() API instead of
allocating and setting the GValue for each construct property that
wasn't passed from the user
Because we are now iterating the linked list of properties in-order we
need to append to that list during class initialising instead of
prepending.
These changes show a very small improvement on the simple-construction
performance testcase (probably just noise) and they improve the
complex-construction case by ~30%.

We were previously preventing implementations of an interface from
specifying G_PARAM_CONSTRUCT for a property of that interface if the
interface didn't specify it itself (or was readonly).
This is something that should only interest the implementation, so we
remove this restriction.
This allows 6 new possible override scenarios:
- writable -> writable/construct
- writable -> readwrite/construct
- readwrite -> readwrite/construct
- writable/construct-only -> writable/construct
- writable/construct-only -> readwrite/construct
- readwrite/construct-only -> readwrite/construct
and we update the testcase to reflect this.

problem first. Also, stop reporting problems after we report the first

Add some comments.
https://bugzilla.gnome.org/show_bug.cgi?id=666616
The property override typecheck was meant to enforce the type on the
overriding property being exactly equal to the type on the interface
property. Instead, g_type_is_a() was incorrectly used.
We could try to enforce equality, but if a property is read-only then it
should be possible for the implementation to type the property with any
subtype of the type specified on the interface (because returning a more
specific type will still satisfy the interface). Likewise, if the
property is write-only then it should be possible for the implementation
to type the property with any supertype.
We implement the check this way.
https://bugzilla.gnome.org/show_bug.cgi?id=666616
Simplify some of the logic in this function.
1) Simplify flag checks as per Colin's suggestions in
https://bugzilla.gnome.org/show_bug.cgi?id=605667
2) Don't repeatedly recheck if class_pspec is NULL.
GObject enforces the following restrictions on property overrides:
- must only add abilities: if the parent class supports
readability/writability then the subclass must also support them.
Subclasses are free to add readability/writability.
- must not add additional restrictions: if the parent class doesn't
have construct/construct-only restrictions then the subclass must
not add them. Subclasses are free to remove restrictions.
The problem with the previous implementation is that the check against
adding construct/construct-only restrictions was being done even if the
property was not previously writable. As an example:
"readable" and "writable only on construct"
was considered as being more restrictive than
"read only".
This patch tweaks the check to allow the addition of
construct/construct-only restrictions for properties that were
previously read-only and are now being made writable.

Either g_type_register_static_simple (used by G_DEFINE_TYPE_EXTENDED)

When the 'conditional' parameter is TRUE, the queue will only be frozen
(ie: have its freeze count increase by one) if it is already frozen.
This will allow us to avoid a freeze-notify-thaw in the case that we
just want to notify on a single property.
Another approach may have been to add an is_frozen() type call and avoid
even increasing the freeze count at all in this case. Unfortunately,
I'm not totally sure what is the exact expected semantics of
simultaneous notifications in multiple threads and this may interact
badly with someone freezing or thawing in between our check and
emission.
Lift the check-if-READABLE and redirect-target logic from out of
g_object_notify_queue_add() into its own function, get_notify_pspec().
Use that function at the site of our two calls to
g_object_notify_queue_add().
This was done as a separate file before, and #include brought it into
gobject.c. That's a bit mad, so stop doing that.
Unfortunately, the insanity steps up a level: gobjectnotifyqueue.c is
installed in the public include dir, so we can't just get rid of it
entirely.
Similar to G_PARAM_DEPRECATED. It will warn only for users of the
signals, so a signal can still be emited without warning, for
compatibility reasons.
Apparently, there is no way user flags could have been used before,
so that shouldn't break anyone.

Some links were broken due to typos, because functionality was removed
in GLib 2.0 or for various other reasons. Fix up as many of them as is
reasonable.
- remove all inline assembly versions
- implement the atomic operations using either GCC intrinsics, the
Windows interlocked API or a mutex-based fallback
- drop gatomic-gcc.c since these are now defined in the header file.
Adjust Makefile.am accordingly.
- expand the set of operations: support 'get', 'set', 'compare and
exchange', 'add', 'or', and 'xor' for both integers and pointers
- deprecate g_atomic_int_exchange_and_add since g_atomic_int_add (as
with all the new arithmetic operations) now returns the prior value
- unify the use of macros: all functions are now wrapped in macros that
perform the proper casts and checks
- remove G_GNUC_MAY_ALIAS use; it was never required for the integer
operations (since casting between pointers that only vary in
signedness of the target is explicitly permitted) and we avoid the
need for the pointer operations by using simple 'void *' instead of
'gpointer *' (which caused the 'type-punned pointer' warning)
- provide function implementations of g_atomic_int_inc and
g_atomic_int_dec_and_test: these were strictly macros before
- improve the documentation to make it very clear exactly which types
of pointers these operations may be used with
- remove a few uses of the now-deprecated g_atomic_int_exchange_and_add
- drop initialisation of gatomic from gthread (by using a GStaticMutex
instead of a GMutex)
- update glib.symbols and documentation sections files
Closes#650823 and #650935
I couldn't tell from reading the documentation whether I had to pass in
an uninitialized value, or a value initialized to the exact type, or
something else. It turns out (from reading the source) that you have to
pass in an initialized value, but you can use any type to which the
property's actual type can be transformed.
So, let's document this.
The code section guarded with toggle_refs_mutex includes a call to
g_object_unref(), which may call toggle_refs_notify(). As the latter
tries to acquire the same mutex, glib locks up.

Since we added g_object_notify_by_pspec(), an efficient way to install

should have a single function to take the static array of GParamSpecs
and iterate it.

because of the variable dllimport/dllexport stuff in gtypes.h that

compiling code that goes into the libglib DLL. Otherwise the compiler
thinks that variables that should be imported from libglib are

The gdatasetprivate.h header includes gatomic.h directly. It all works
well in GLib, but inside GObject it will trigger the single inclusion
guard.
Since this is a private header, and it's kind of a special case, one way
to fix it is to declare GLIB_COMPILATION around it and fool the single
inclusion guard in gatomic.h into thinking we're compiling GLib and not
GObject.
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 static markers and systemtap tapsets for:

This works around the need to take a custom mutex twice and add the
object to a GSList of objects that are currently in construction for the
common case. Only when the constructor is overwritten do we use the
previous behavior and allow things like singleton objects.
The only slightly incompatible change is that previously, it was ok to
call g_object_set() on construct-only properties while the object was
initialized. This will now fail. If that behavior is needed, setting a
custom constructor that just chains up will reenable this functionality.

* *.c: moved includes back to the top of the files (before gtk-doc
SECTION comments). Add "config.h" in all files and move system
included before glib includes. Remove trailing whitespace from
SECTION comments and did some reformatting where lines were overly
long, no documentation content was changed.

* gobject.[hc]: invoke GObjectClass.constructed() only for newly
constructed objects, and invoke it while the notify queue is
still being frozen, after all CONSTRUCT* properties have been
set and before random other properties are being set.
* applied modified patch from Ryan Lortie to implement
GObjectClass.constructed() to fix#425324.
2007-04-02 Ryan Lortie <desrt@desrt.ca>
* gobject/gobject.h: Add 'constructed' vcall to GObjectClass.
* gobject/gobject.c (g_object_newv): call ->constructed() as last
step of object construction.

* glib-mkenums.in: fixed to print usage and version info on STDOUT
(#322502).
* gobject.c (g_initially_unowned_init): restore ; after G_DEFINE_TYPE.
Wed Aug 23 10:35:32 2006 Tim Janik <timj@gtk.org>
* gobject.[hc]: changed return value of g_value_dup_object(), fixes#343292.

* gobject/glib-genmarshal.[c1]: added new command-line option
"--internal" that can be used to let glib-genmarshal generate
internal functions using the G_GNUC_INTERNAL attribute (bug #346647).
Wed Aug 16 13:55:08 2006 Tim Janik <timj@imendio.com>
* gobject.c: conditionally thaw the notify queue after construction,
so we don't trigger warnings when trying to thaw an unfrozen singleton.
Tue Mar 7 17:09:07 2006 Tim Janik <timj@gtk.org>
* gobject.c (g_object_compat_control): added case3 to hand out the
original floating flag handler. required by gtk+ >= 2.10.
Thu Dec 22 14:59:24 2005 Tim Janik <timj@imendio.com>
* gvaluetypes.[hc]: implemented G_TYPE_GTPYE. applied patch
from matthias which implements GType accessors for GValue.
* gparamspecs.[hc]: applied patch from matthias which
implements G_TYPE_PARAM_GTYPE.
* gobject.[hc]:
GUnowned: introduced a new object type that has an initially
floating reference.
g_object_compat_control(): allow setting of a floating flag handler.
Wed Nov 23 18:01:46 2005 Tim Janik <timj@imendio.com>
* gobject.[hc]: added floating reference count.
g_object_is_floating():
g_object_ref_sink(): new functions to deal with floating references.
g_object_force_floating(): new funciton for object implementations
to set the floating flag.
* gobject.c (g_object_init): make objects initially floating.
Wed Nov 23 17:58:13 2005 Tim Janik <timj@gtk.org>
* gparam.[hc]: added g_param_spec_ref_sink().
Mon Aug 1 23:00:42 2005 Tim Janik <timj@imendio.com>
* gclosure.c: turned all modifications to the first 32 integer bits in a
closure into atomic accesses. wrapped write accesses into special macros
to keep the atomic modification logic in a single place. comment cleanups.
* gclosure.h: made all atomicly accessed closure fields volatile.
* gobject.h: made ref_count field volatile.
