Take this test out of 'make check'. It's causing problems for a lot of people
due to fact that it's essentially a forkbomb. It's causing failures for Debian
on ARM and it's DoSing coredumps to system crash collectors.
The conditional only covers registration of the master, not the
subprocess parts. This is because g_test_slow() always return FALSE in
the subprocesses, so they would fail to run if we didn't register them
unconditionally.
This is the sole piece of code in GLib where we make use of the
stack growing direction. And this test proves that we have been
getting the direction wrong all these years...
The signals queued while notify is frozen are emitted in
reverse order, while omitting duplicates. The lack of documentation
for this was pointed out in

In Windows development environments that have it, <unistd.h> is mostly
just a wrapper around several other native headers (in particular,
<io.h>, which contains read(), close(), etc, and <process.h>, which
contains getpid()). But given that some Windows dev environments don't
have <unistd.h>, everything that uses those functions on Windows
already needed to include the correct Windows header as well, and so
there is never any point to including <unistd.h> on Windows.
Also, remove some <unistd.h> includes (and a few others) that were
unnecessary even on unix.

Assume all supported platforms implement C90, and therefore they
(correctly) implement atexit(), memmove(), setlocale(), strerror(),
and vprintf(), and have <float.h> and <limits.h>.
(Also remove the configure check testing that "do ... while (0)" works
correctly; the non-do/while-based version of G_STMT_START and
G_STMT_END was removed years ago, but the check remained. Also, remove
some checks that configure.ac claimed were needed for libcharset, but
aren't actually used.)
Note that removing the g_memmove() function is not an ABI break even
on systems where g_memmove() was previously not a macro, because it
was never marked GLIB_AVAILABLE_IN_ALL or listed in glib.symbols, so
it would have been glib-internal since 2004.

GMappedFile is current unintrospectable, because it's not a registered
box type. It already has reference counting functions, so there's
little reason not to box it.
This commit adds GMappedFile to the hoard of other boxes types handled
by gboxed.c

Rather than keeping a global list of objects that are being
constructed, use qdata on the object itself like we do with several
other properties now.
https://bugzilla.gnome.org/show_bug.cgi?id=661576
If a constructor() implementation created an object but then unreffed
it rather than returning it, that object would get left on the
construction_objects list, which would cause problems later when that
memory location got reused by another object.
"Fix" this by making it fail intentionally, and add a test for it (and
for the normal, working singleton case).

GBindingTransformFunc called its arguments "source_value" and
"target_value", but in the transform_from function of a bidirectional
binding, "source_value" comes from the target object, and
"target_value" comes from the source object, which quickly gets
confusing if you need to use g_binding_get_source(), etc, in the
function.
Of course developers can call their transform function arguments
whatever they want, but many will copy from the headers/docs to start
out, so use less confusing names here ("from_value" and "to_value").
Also, fix the documentation to describe the bidirectional case
correctly.

Add NULL check and return after calls to g_param_spec_internal in GParamSpec
creation functions. This avoids glib crashing due to things like badly named
properties.

Apple's GCC compilers cannot deal well with 64-bit pointers in
transparent unions on ppc64, so compilation of
_G_DEFINE_BOXED_TYPE_BEGIN was failing. Fortunately glib already
provides a fallback for compilers that can't deal with it; this adds
this specific case to the check.

g_type_class_add_private() was doing
g_assert (node->data->instance.private_size <= 0xffff);
but that field is a guint16, so the check was a no-op. (Noticed by
clang, but not gcc for some reason.) Fix it to do the math in a gssize
variable and do the bounds checking there before updating the struct
field.

Convert {glib,gobject,gio}/tests to use the automake TAP driver
and test harness instead of gtester. To do so, we add a glib-tap.mk
that provides the same interface as glib.mk, except for the
reporting and coverage testing functionality. Eventually, we may
want to replace glib.mk with it. I've not yet converted the
toplevel tests/ directory, since it mixes gtestutils tests with
other binaries.

Fix the warnings when compiling and linking the probes files by
calling dtrace with all the -W flags removed from CFLAGS (since dtrace
generates bad C code), and with CC set to "libtool --mode=compile ..."
(so that it will output a proper .lo file and libtool won't warn when
linking it into the .la).

Just like g_object_notify, check for a zero ref_count in
g_object_notify_by_pspec and leave if it is 0.
This allows using functions in ->finalize() that possibly also
notify a property change on the object. Previously,
this resulted in an error from g_object_ref.

We need a TypeName_private_offset variable defined by the macros used to
register dynamic types. We also need to call the adjust_private_offset()
function inside class_init(). G_ADD_PRIVATE_DYNAMIC only sets the size
of the private data structure, and relies on the behaviour of the
g_type_class_adjuset_private_offset() function to register the private
data structure at class init time if passed a value greater than zero.
This allows using G_PRIVATE_OFFSET with dynamic types.
Otherwise in e.g. the gnome-ostree integrationtest system, we
end up sending SIGUSR1 to the *entire session*, which triggers
various badness in untested debugging paths from gnome-session.
This test worked when compiled without optimization, but fails with
-O2. Presumably we just happened to find the GMainLoop off the stack
somewhere.

GPid is a HANDLE (aka void *) on Windows, not an int, so treat pid
accordingly on Windows, as using pid as a gulong directly would likely be
undesirable on Windows

For the glib-defined source types, and any source type that defines a
closure callback but not a closure marshal, use
g_cclosure_marshal_generic. And then remove all the other remaining
source closure marshals.

When using the GLIB_VERSION_MAX_ALLOWED macro to define the upper bound
of allowed API the G_DEFINE_TYPE_EXTENDED starts warning about the newly
added g_type_class_adjust_private_offset() function; this effectively
introduces a run-time dependency on GLib 2.38 even if we don't use its
API explicitly.
https://bugzilla.gnome.org/show_bug.cgi?id=703191
As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
For static types, it should be possible to register a private data
structure right when we are registering the type, i.e. from the
get_type() implementation. By allowing this, we can take advantage of
the existing type definition macros to cut down the amount of code
necessary (as well as the knowledge baggage) when creating a new type.
The main issue with this new feature is that it cannot be mixed with the
old idiomatic way of adding private instance data by calling a function
in the middle of the class_init() implementation, as that imposes the
additional constraint of initializing the whole type hierarchy in order
to retrieve the offset of the private data in the GTypeInstance
allocation.
For this reason we are going to follow a two-step process; in the first
step, we are going to introduce the new (semi-private) API to register
the intent to add private instance data from within the get_type()
implementation, and hide it behind a macro; at the same time, the
G_DEFINE_TYPE_EXTENDED macro is going to be modified so that it will
register the private instance data if the macro was used, using a new
(semi-private) function as well. Once we have migrated all our code, we
will make the first new function perform the actual private data
registration, and turn the second new function into a no-op. This should
guarantee a transparent migration of existing code to the new idiomatic
form.
