Add an #ifdef G_OS_UNIX around the GLIB_AVAILABLE_IN_ALL annotation on
the _get_type() functions for GLocal{File,Directory}Monitor.
These symbols are in private header files and are only exported so that
the in-tree file monitoring modules can subclass. This is only needed
on UNIX and was therefore never part of the public ABI on Windows.
Caught by Dieter Verfaillie.
Commit 282366c326 unnecessarily (skip)ed all the GParamSpec constructors like
g_param_spec_bool(). Make those introspectable by dropping the (skip) and
adding proper transfer annotations.
Keep g_param_spec_value_array() skipped as GValueArray is deprecated.
One of our testcases builds a small giomodule for testing the loading of
modules containing resources. Unfortunately, this module gets built
using the same CFLAGS as the rest of GLib, including the visibility
flags (defaulting to hidden).
Use "config.h" to get a declaration of _GLIB_EXTERN that will export
symbols properly and use it to annotate the necessary APIs.
One of the features of our new symbol exporting regime is that it forces
config.h to be included at the top of every .c file.
This was missed in gthread-impl.c.
The only reason this wasn't noticed is because nothing in this file is
being used anymore. We need those symbols to continue to be exported
for reasons of ABI backwards compatibility, however.
The kqueue file monitoring backend was misusing G_GNUC_INTERNAL for want
of 'static' in a couple of places and also using it to declare a lock
that was never used at all.
Fix those up.
With visibility now under the control of __declspec(dllexport) we no
longer need to build .def files or use them for building our various
.dll files.
.def files used to be installed (even though it is only really useful
when creating the .dll or .lib file). Don't do that anymore either.
The Makefiles still contain rules to create a .lib file for use with
Visual Studio and these rules require .def files. There are special
requirements to using these rules (like having installed and setup
Microsoft tools for use during the build) and therefore the problem of
creating a .def file for use with them is left open to anyone willing to
make the effort. Many options are available depending on which
toolchain is in use (dlltool, pexport, gendef, dumpbin.exe, just to name
a few).
If we can find a free tool for creating .lib files in the future, we
should probably revisit this issue and add proper support back to our
build system.
Check for -fvisibility=hidden as a supported CFLAG.
If it is supported, use it and emit an AC_DEFINE to change the meaning
of _GLIB_EXTERN to include the GNU attribute for marking symbols as
public: __attribute((visibility("default"))).
This will override the public definition of _GLIB_EXTERN for any file
which does #include "config.h" (forcing all our .c files to do so, as a
side effect).
If we're on mingw, assume that -fvisibility will work and also throw in
a __declspec(dllexport) for good measure. This will allow us to move
away from using a .def file to create the the various DLLs.
It's possible that there may be compilers that accept
-fvisibility=hidden but don't accept the GNU attribute for making
symbols public again -- we will hopefully receive bugs if any of those
exist.

We have a public symbol 'glib_on_error_halt' that is exported from
gbacktrace.c without appearing in a header, presumably with the
intention that people will be able to hit it from their debugger.
Mark it as GLIB_AVAILABLE_IN_ALL from inside the .c file...

This macro simply evaluates the "extern" unless it has been explicitly
defined to something else.
All of the version macros (including the unversioned deprecation markers
and GLIB_AVAILABLE_IN_ALL) now include _GLIB_EXTERN as part of their
definition.
G_INLINE has also been modified to use _GLIB_EXTERN where appropriate.
This macro should never be used outside of the gmacros.h/gversonmacros.h
headers.
The effect of this patch is that "extern" has now been added to all
functions declared in installed headers. Strictly speaking, this is
something we should have had all along...
GLIB_VAR and GOBJECT_VAR have also been modified to use _GLIB_EXTERN on
non-Windows, instead of "extern" which they were using before. The
eventual goal is to use the normal version/deprecation macros on
exported variables and drop GLIB_VAR but we need to see how this will
work on Windows before we go ahead with that.

Add the GLIB_AVAILABLE_IN_ALL annotation to all old functions (that
haven't already been annotated with the GLIB_AVAILABLE_IN_* macros or a
deprecation macro).
If we discover in the future that we cannot use only one macro on
Windows, it will be an easy sed patch to fix that.

glib-mkenums is not currently clever enough to know which version an
enum type was added in, so just mark all the _get_type() functions as
available in all versions.

Add a macro to declare that a particular symbol is available in all
versions of GLib.
All newly-added symbols should have proper version macros (like
GLIB_AVAILABLE_IN_2_36) and this macro is less likely to get used 'by
accident' for those than one with a name like GLIB_EXTERN or
GLIB_PUBLIC.

This allows compilation with clang without errors, even when
-Wformat-nonliteral is active (as long as there are no real cases of
non literal formatting).

g_input_stream_real_skip_async() wants to use read_async() normally,
but will use skip() in a thread instead if it sees that read_async()
will end up using threads. Except that the test for "will read_async()
use threads" never got updated to know about the GPollableInputStream
support in read_async(), so it was doing the wrong thing in that case.
Fix.
Also remove a small bit of pre-GTask cruft noticed nearby.

For OSTree, I use Gio and also really care about performance. It's
disturbing to see open('.hidden') all over my straces and such. At
the moment I have an explicit set of things to query, as opposed to
"standard::*", since even before this that also implies an lstat() of
the parent directory.
This matches up with what we do for all the other attributes.

Since we're dynamically loading objects, after the g_type_init()
change, we now need to ensure people building with --as-needed don't
lose the DT_NEEDED on libgobject.

Some OS (e.g. OpenBSD) do not implement IP v4-mapped addresses. When
this is the case, then we get a "Connection refused", so force the test
to pass to that further tests can run.

The attached patch adds support for the btrfs "clone" ioctl which
makes Copy-on-Write reflinks, resulting in cheap O(1) copies when
source/destination are on the same filesystem. The ioctl itself is
quite straightforward, and GNU coreutils has had support since 7.5
(--reflink=auto --sparse=auto).
The ioctl only operates on regular files and symlinks, and always
follows symlinks; checks have been added accordingly.
This patch would be very useful for everyone who uses btrfs
filesystems (Meego folks for instance). On systems that don't have
btrfs, or if the the source is not on a btrfs filesystem, the ioctl
returns EINVAL, and the fallback code is triggered. Hence this will
cause no problems for non-btrfs users.

a5876e5f made GMemoryInputStream subclassable, but accidentally broke
read_async() and skip_async() in the process. The immediately
following e7983495 fixed read_async() (and added a test for it), but
skip_async() accidentally got... skipped.
Fix it now and add a test for it.
Also, GMemoryInputStream's skip_async() was assuming that skip() could
never fail, which is true of its own implementation, but might not be
true of a subclass's, so do proper GError handling too.
Add a check to prevent adding an interface to a class that has already
had its class_init done.
This is an incompatible change but it is suspected that there are not
many users of this functionality. Two known exceptions are pygobject
(fixed in bug 686149) and our own testsuite (affected tests have been
temporarily disabled by this patch).
Once we confirm that nobody else is using this functionality we can
remove a rather large amount of code for dealing with this case.

This will let us drop the dbus-python dependency.
The C version does not 100% reproduce all the hash table
and array manipulation of the python version, but the tests
do not rely on it anyway.
