They just listed built files. Since the move to Meson, these are all
kept in a separate build directory, not the source tree, so don’t need

They take too long and time out, and are not particularly useful to run
under valgrind because they aren’t designed to test code coverage.

In all these cases we don't really care about running the test file,
while building and basic execution it is relevant.
Also they don't support TAP at all.
Meson supports tap protocol results parsing, allowing us to track better
the tests that are running (and the ones that are actually skipped) without
manually parsing the test output.
However this also implies that using the verbose mode for a test doesn't
show its output by default (unless there are failures).
This can cause a `NULL` dereference on the next line if there is no
`TypeNode` for `iface_type`, for example if `iface_type ==
G_TYPE_INVALID`.
Unlikely, but possible since this API is public.

We can get a "-Wcast-align", if the target type that we cast to ("ct") has a
larger alignment than GTypeInstance.
That can happen on i686 architecture, if the GObject type has larger
alignment than the parent struct (or GObject). Since on i686, embeding
a "long long" or a "long double" in a struct still does not increase
the alignment beyond 4 bytes, this usually only happens when using the
__attribute__() to increase the alignment (or to have a field that has
the alignment increased).
It can happen on x86_64 when having a "long double" field.
The compiler warning is hard to avoid but not very useful, because it purely
operates on the pointer types at compile time. G_TYPE_CHECK_INSTANCE_CAST()
instead asserts (in non-optimized mode) that the pointer really points
to the expected GTypeInstance (and if that's the case, then the alignment
should be suitable already).
This is like in commit ed553e8e30 ('gtype: Eliminate -Wcast-align warnings
with G_TYPE_CHECK_INSTANCE_CAST'). But also fix the optimized code path.
With the unpatched G_TYPE_CHECK_INSTANCE_CAST() macro, the unit test would
now show the problem (with gcc-9.3.1-2.fc30.i686 or
gcc-12.2.1-4.fc37.x86_64):
$ export G_DISABLE_CAST_CHECKS=1
$ export CFLAGS='-Wcast-align=strict'
$ meson build
$ ninja -C build

When an object is revitalized and a notify callbacks increased the reference
counter of the object, we are calling the toggle notifier twice, while it
should only happen if also the actual reference count value is 1 (after
having been decremented from 2).
If an object gets revitalized during the dispose vfunc, we need to call
toggle refs notifiers only if we had 2 references and if the object has
the toggle references enabled.
This may change in case an object notifier handler changes this status,
so do this check only after we've called the notifiers so that in case
toggle notifications are enabled afterwards we still call the handlers.
Otherwise this test will succeed at build-time, but will fail when run
as an as-installed test via ginsttest-runner.

This can be used to mark entire types as deprecated,
and trigger a warning when they are instantiated
and `G_ENABLE_DIAGNOSTIC=1` is set in the environment.
There's currently no convenient macros for defining
types with the new flag, but you can do:
```c
_G_DEFINE_TYPE_EXTENDED_BEGIN (GtkAppChooserWidget,
gtk_app_chooser_widget,
GTK_TYPE_WIDGET,
G_TYPE_FLAG_DEPRECATED)
...
_G_DEFINE_TYPE_EXTENDED_END ()
```

Some of GLib's unit tests are under an apparently GLib-specific
permissive license, vaguely similar to the BSD/MIT family but with the
GPL's lack-of-warranty wording. This is not on SPDX's list of
well-known licenses, so we need to use a custom license name prefixed
with LicenseRef if we want to represent this in SPDX/REUSE syntax.
Most of the newer tests seem to be licensed under LGPL-2.1-or-later
instead.

This allows them to be referenced in other symbols value computation.
In addition, this fixes the automatically assigned value of a public
symbol that is preceded by a private one:
typedef enum {
/*< private >*/
ENUM_VALUE_PRIVATE,
/*< public >*/
ENUM_VALUE_PUBLIC, <--- value is 1, not 0.
} SomeExampleEnum;
We have tests that are failing in some environments, but it's
difficult to handle them because:
- for some environments we just allow all the tests to fail: DANGEROUS
- when we don't allow failures we have flacky tests: A CI pain
So, to avoid this and ensure that:
- New failing tests are tracked in all platforms
- gitlab integration on tests reports is working
- coverage is reported also for failing tests
Add support for `can_fail` keyword on tests that would mark the test as
part of the `failing` test suite.
Not adding the suite directly when defining the tests as this is
definitely simpler and allows to define conditions more clearly (see next
commits).
Now, add a default test setup that does not run the failing and flaky tests
by default (not to bother distributors with testing well-known issues) and
eventually run all the tests in CI:
- Non-flaky tests cannot fail in all platforms
- Failing and Flaky tests can fail
In both cases we save the test reports so that gitlab integration is
preserved.
In principle we could script this so that each max-version.c is compiled
26 times, once per possible MAX_VERSION, but I haven't implemented
that here: just pinning to the oldest possible version is sufficient to
reproduce #2796.
These aren't included in the installed-tests, since they don't really
do anything at runtime (the important thing is that they compile
without warnings).

When collecting varargs, ignore the NOCOPY_CONTENTS
flag for variants. That is what our docs advice for
refcounted types, and it fixes a regression that
was inadvertendly introduced when we stopped doing
some extra GValue copies.

For unclear reasons, universal_newlines=True doesn't seem to set the
text encoding correctly. Even if I set only encoding='utf-8', the test
fails. The combination here works for me, \o/.

This goes undiagnosed under normal circumstances, but is a critical
warning (which is fatal by default) under G_ENABLE_DIAGNOSTIC. This is a
programming error, so we should only exercise it under
g_test_undefined(), and only in a test that is intentionally doing this
(as in the previous commit).

This was previously exercised (probably by mistake) in
gobject/tests/type.c, but without making any assertions about what
happened, and the test would fail under G_ENABLE_DIAGNOSTIC if GLib was
compiled with debug enabled.

We've various macros definitions that are depending using C++ features
that may not work in all the standard versions, so recompile the cxx
tests that we have in all the ones we want to support.
