The implementation didn’t match the documentation. The implementation
has the right behaviour (wrt not allowing embedded nuls, validating
UTF-8, and returning a default value if an invalid string is detected),
so keep that and fix the documentation to match.
The [`GVariant`
specification](https://people.gnome.org/~desrt/gvariant-serialisation.pdf)
is incorrect on this point, and the implementation of GLib was
purposefully changed after the specification was published (but before
`GVariant` became API-stable in GLib). The behaviour in GLib
(specifically concerning all strings being in UTF-8) is consistent with
D-Bus.

In glib-networking#127, it was reported that we don't properly implement
the documented behavior of these properties. However, we cannot fix it
because libsoup relies on the implemented behavior, and it's hard to
change that without cascading breakage. The practical solution is to
adjust our documentation to match reality. There should be no downsides
to this, and compat risk of changing the documentation is much smaller
than risk of changing the implementation, so I think this is the best we
can make of an unfortunate situation. See glib-networking#127 for full
discussion and glib-networking#129 for the regression when we attempted
to match the documented behavior.
Some editors automatically remove trailing blank lines, or
automatically add a trailing newline to avoid having a trailing
non-blank line that is not terminated by a newline. To avoid unrelated
whitespace changes when users of such editors contribute to GLib,
let's pre-emptively normalize all files.
Unlike more intrusive whitespace normalization like removing trailing
whitespace from each line, this seems unlikely to cause significant
issues with cherry-picking changes to stable branches.

cc.has_function() provide false positive for Android-20 and earlier; the fix is in Meson 0.54.2. People attempting to cross-compile previously wouldn’t have been able to get it to work without manual intervention, so the dependency bump for this platform is not an additional obstacle for them.
While these assertions look right at the first glance,
they actually crash the program. That's because GObject
insists on initializing all construct-only properties
to their default values, which results in
g_win32_registry_key_set_property() being called multiple
times with NULL string, once for each unset property.
If "path" is actually set by the caller, a subsequent
call to set "path-utf16" to NULL will fail an assertion,
since absolute_path is already non-NULL.
With assertions moved the set-to-NULL calls bail out before
an assertion is made.
This is more efficient and also much easier since we already have the
memory allocated that we're going to return from the function. No need
to do that ourselves or reverse a list.
We're roundtripping from a valid file, but we should also roundtrip from
a newly created GBookmarkFile, to ensure that we set all the necessary
fields.
Just like we do for the other fields. Otherwise, when we serialise the
item, we're going to hit a segmentation fault when trying to format a
NULL GDateTime.
This should be generated based on the available SDK versions and the
iPhone version you want to target, but that's something we can do
when adding macOS and iOS CI.
They use the `time_t` type, which is not year 2038 safe on 32-bit
systems, so have to be deprecated.

Fixes: #1931
In preparation for deprecating the old APIs. This shouldn’t functionally
affect the tests.

These are alternatives to the existing `time_t`-based APIs, which will
soon be deprecated due to `time_t` only being Y2038-safe on 64-bit
systems.
The new APIs take a GDateTime instead.

This updates gdbus-codegen.xml to include documentation for the
--symbol-decorator, --symbol-decorator-header and
--symbol-decorator-define options, which is used to help to export
symbols in the generated code.
This ensures that we do really export the symbols for Visual
Studio-style builds, by using _GLIB_EXTERN to decorate the generated
prototypes and including config.h so that we are sure the symbols are
actually exported.
This adds three options to gdbus-codegen so that we may be able to
use a self-defined symbol decorator, such as _GLIB_EXTERN, to decorate
the generated prototypes, to be used possibly to export the symbols, if
needed.
The other two options allows including headers that are required for the
specified symbol decorator to be usable and preprocessor macros that are
required for the symbol decorator to be defined appropriately, also when
needed.
When targeting mingw on architectures other than x86, the earlier cases
don't apply, and the final fallback, raise(SIGTRAP) isn't usable there.
GCC and Clang both support __builtin_trap(), so in case we have no
other alternatives, and are on windows (where raise() isn't available),
we can resort to this.
Have the generated .c code decorate the prototypes with "G_MODULE_EXPORT"
instead of "extern" when --internal is not being used, so that we also
export the symbols from the generated code on Visual Studio-style
compilers. If --internal is used, we decorate the prototypes with
"G_GNUC_INTERNAL", as we did before.
Note that since the generated .c code does not attempt to include the
generated headers (if one is also generated), the gnerated headers are
still generated as they were before.
