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.
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.

In an attempt to avoid some potential future abuses of the GParamSpec
API, qualify the 'name' field of the structure as 'const' and add a
comment noting that it is an interned string.
This is a theoretical API break, but it will only ever result in
warnings -- and even then, only if you were already doing something
questionable.
Clean up some of the warnings that were caused internally in gparam.c
from these changes.
This function implements the following logic:
if (g_variant_is_floating (value))
g_variant_ref_sink (value);
which is used for consuming the return value of callbacks that may or
may not return floating references.
This patch also replaces a few instances of the above code with the new
function (GSettings, GDBus) and lifts a long-standing restriction on the
use of floating values as the return value for signal handlers by
improving g_value_take_variant().

The -e parameter to echo isn't recognized by echo in POSIX sh,
but isn't needed when no escaped characters need to be
interpreted.
This fixes building glib with a mingw cross compiler on Mac OS X.

To help cross compilation, don't use glib-genmarshal in our
build. This is easy now that we have g_cclosure_marshal_generic().
In gobject/, add gmarshal.[ch] to git (making the existing entry
points stubs).
In gio/, simply switch to using g_cclosure_marshal_generic().

Rather than having the gtk-doc build machinery have a list of header
files to exclude, change the GLib build to dump a list of public
header files generated from the maintained Makefile.am files for
each of glib/, gobject/, gio/.
Also, for glib, always install glib-unix.h, even on non-Unix
platforms, for the same reason we install gwin32.h even on Unix.

The check for _MSC_VER here is not necessary here because:
-One cannot compile GLib out-of-the-box with VS 2003 (let alone VS6
or earlier) since GLib 2.22.4 or so.
-This code compiles fine with the currently-supported VS versions
(2008/2010) without the error mentioned in the comments.
This will close Bug 652002.

From discussion, GVariantIter is not useful for bindings, but
GVariantBuilder may be.

- 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
The grouping in files/headers is not used anymore, and
the function attributes neither. Adapt abicheck scripts
and .def file generation rules accordingly.
The hash table used exclusively for looking up types by name used to map
quarks => types. But we can easily make it map strings => types, which
avoids the quark lookup. And that in trun avoids taking a lock and
consulting another hash table. So this change should make
g_type_from_name() roughly twice as fast.
In some cases, signal arguments have to be collected, even if there are i
no signal handlers connected (e.g. for GVariant parameters, where collection
consumes a floating variant).
Based on a patch by Christian Persch.
Bug #643624.
These are the updates to the autotools files to
ensure the expansion of the GIO, GLib and GObject
project files (*.vcxproj, *.vcxproj.filters) and to
enable the distribution of the VS2010 project files
The actual VS2010 project files will follow shortly
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.

Previously, dumping a GValue holding a GStrv just yielded "((GStrv *)
0xDEADBEEF)". I think it'd be more useful to dump a Python list-style
representation of the GStrv's contents, if it's not NULL.
Fixes: <https://bugzilla.gnome.org/show_bug.cgi?id=629192>
Since we added g_object_notify_by_pspec(), an efficient way to install
and notify properties relies on storing the GParamSpec pointers inside
a static arrays, like we do for signal identifiers.
Instead of multiple calls to g_object_class_install_property(), we
should have a single function to take the static array of GParamSpecs
and iterate it.

This should fix bug #628952.
Don't include glib/gdatasetprivate.h directly. Especially don't define
GLIB_COMPILATION when doing that, as that causes breakage on Windows
because of the variable dllimport/dllexport stuff in gtypes.h that
checks GLIB_COMPILATION. That macro really should be defined only when
compiling code that goes into the libglib DLL. Otherwise the compiler
thinks that variables that should be imported from libglib are
actually defined in the code being compiled.
Just call g_atomic_pointer_get() as such, don't bother with
G_DATALIST_GET_FLAGS.
