While we automatically define cleanup functions for the module, we don't
do it for the module class.
This will allow to manage the ownership of the class when reffing it
without having to cast it to GTypeClass.
g_atomic_pointer_compare_and_exchange() should work with const pointers.
Add a test for that.
It seems clang 9.0.0-2.fc32 does not like this:
../glib/tests/atomic.c:93:9: warning: incompatible pointer types passing 'typeof ((((void *)0))) *' (aka 'void **') to parameter of type 'const char **' [-Wincompatible-pointer-types]
res = g_atomic_pointer_compare_and_exchange (&vp_str, NULL, str);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../glib/gatomic.h:192:44: note: expanded from macro 'g_atomic_pointer_compare_and_exchange'
__atomic_compare_exchange_n ((atomic), &gapcae_oldval, (newval), FALSE, __ATOMIC_SEQ_CST, __ATOMIC_SEQ_CST) ? TRUE : FALSE; \
^~~~~~~~~~~~~~
../glib/tests/atomic.c:96:9: warning: incompatible pointer types passing 'typeof ((((void *)0))) *' (aka 'void **') to parameter of type 'const char **' [-Wincompatible-pointer-types]
res = g_atomic_pointer_compare_and_exchange (&vp_str_vol, NULL, str);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../glib/gatomic.h:192:44: note: expanded from macro 'g_atomic_pointer_compare_and_exchange'
__atomic_compare_exchange_n ((atomic), &gapcae_oldval, (newval), FALSE, __ATOMIC_SEQ_CST, __ATOMIC_SEQ_CST) ? TRUE : FALSE; \
^~~~~~~~~~~~~~
Note that this clang version already issues various compiler warnings for
this test. This merely adds another case to check.
Eventually g_atomic_pointer_compare_and_exchange() should be fixed to
avoid compiler warnings.
Actually there is a problem. When you try to use g_atomic_pointer_compare_and_exchange()
with const pointers, it is also not working, because the implementation
as a function expects "void *" arguments. As the test also shows. As such,
it's probably not portable to use g_atomic_pointer_compare_and_exchange()
with const pointers at all. However, the macro implementation is (with the right
compiler) fine with that, so it's an easy "mistake" to make.
The `G_TYPE_IS_INSTANTIATABLE()` check is redundant with a precondition
on the function.
The `g_type_class_peek()` check seems like a pointless restriction: it
should be possible to check for a signal from a class init function.

A bug in `clang-format-diff.py` was causing it to only output the
formatting diff for the first incorrectly-formatted file, rather than
the diffs for all files.
That’s not so helpful for reformatting an entire MR in one go. Fix it.

The valgrind analysis stage inherits from existing artefacts, so make
sure to reset the permissions on the glib build directory to avoid a new
build failing.

This reverts commit 398c048c66.
It got removed because it used to cause build issues, but now that we
have a CI let's hope it won't be a problem any more.
Those tests require Python, gobject-introspection and python-dbusmock
making them unsuitable to be run within the uninstalled test suite.
There are no restrictions of dependencies when it comes to installed
tests so use those to exercise GMemoryMonitor.
With debug enabled, g_dbus_connection_call_done() will throw a
g_warning() if the call failed (on purpose or not) while trying to the
serial of a non-existant reply.

This is a reimplementation of commit
4aba03562b from Will Thompson, but
conditional on the caller passing `--glib-min-version 2.64` to
`gdbus-codegen` to explicitly opt-in to the new behaviour.
From the commit message for that commit:
Previously, if a method was not annotated with org.gtk.GDBus.C.UnixFD
then the generated code would never contain GUnixFDList parameters, even
if the method has 'h' (file descriptor) parameters. However, in this
case, the generated code is essentially useless: the method cannot be
called or handled except in degenerate cases where the file descriptors
are missing or ignored.
Check the argument types for 'h', and if present, generate code as if
org.gtk.GDBus.C.UnixFD annotation were specified.
Includes a unit test too.

This can be used by callers to opt-in to backwards-incompatible changes
to the behaviour or output of `gdbus-codegen` in future. This commit
doesn’t introduce any such changes, though.
Documentation and unit tests included.
