Instead of letting each directory to find its way to link with libdl,
it is easier to put the check in the top level, so its result can be
used by all directories.
It is a follow-up of https://gitlab.gnome.org/GNOME/glib/merge_requests/810.
The header file was installed when building using autotools, but was
inadvertently omitted in the meson targets.
Luckily, ABI is not impacted, since gnativesocketaddress.c was always
compiled and linked into libgio.
Fixes: #1854
The gobject introspection comments have a reference to an incorrect
class: they have, as 'self', the GSubprocess class instead of
GSubprocessLauncher.
This patch fixes this.
g_settings_backend_watch() uses a weak notify for keeping track of
the target. There's an explanation why this is supposed to be safe but
that explanation is wrong.
The following could happen before:
1. We have the target stored in the watch list
2. The last reference to the target is dropped in thread A and we end up
in g_settings_backend_watch_weak_notify() right before the mutex
3. g_settings_backend_dispatch_signal() is called from another thread B
and gets the mutex before 2.
4. g_weak_ref_init() is called on the target from thread B, which at
this point has a reference count of exactly one (see g_object_unref()
where it calls the weak notifies)
5. Thread A continues at 3. and drops the last reference and destroys
the object. Now the GWeakRef from 4. points to a destroyed object. Note
that GWeakRefs would be cleared before the weak notifies are called
6. At some later point another thread g_weak_ref_get() is called by
g_settings_backend_invoke_closure() and accesses an already destroyed
object with refcount 0 from the GWeakRef created in 4. by thread B (or
worse, already freed memory that was reused).
Solve this by actually storing a GWeakRef of the target in the watch
list and only access the target behind it via the GWeakRef API, and then
pass a strong reference to the notification dispatch code.
The weak notify is only used to remove the (potentially with empty
GWeakRef) target from the list of watches and the only place that
compares the target by pointer instead of going through the GWeakRef
API.

If we fail to create a GWinhttpFile for a URI (for example, because it’s
an invalid URI or is badly encoded), don’t just return NULL. Instead,
fall back to the wrapped VFS which might be able to handle it instead.

It can return NULL if the URI was badly encoded or couldn’t be handled
by Windows’ API.

It cannot return a NULL value, as none of its callers have error
handlng. Add an assertion to check the values returned by the VFS
implementations.

This fixes use of `GIO_USE_VOLUME_MONITOR=help`, and simplifies the
code. The reason this wasn’t used already seems to just be because it
was missed when `_g_io_module_get_default_type()` was introduced in
2013. The previous `get_default_native_class()` code in
`gunionvolumemonitor.c` was introduced in 2007.

This fix build error for projects that use gnome.compile_resources()
when glib is built as a subproject and not installed on the build
machine.
Note that this is not working for cross compilation cases, because it
would require to compile everything twice (for host and build machines).
A better solution would be to rewrite those tools in python. See #1859.
They use the deprecated GTimeVal type, which is not year 2038 safe, so
have to be deprecated.

These are alternatives to g_file_info_{get,set}_modification_time(),
which will soon be deprecated due to using the deprecated GTimeVal
type, which is not year 2038 safe.
The new APIs take a GDateTime instead.

The event source used to handle inactivity_timeout doesn't hold a
reference on the application. Therefore, it is possible for callback
function of the event source to run after the application has been
freed, leading to use-after-free problem. To avoid the problem, we
should remove the event source before the application is freed.
This should fix SIGBUS crash of gio/tests/gapplication on FreeBSD.

These are here to prevent linker errors, since `gcontenttype.[ch]`
aren’t compiled on Windows or macOS.
The implementations are stubs to be filled out by someone who knows each

Fixes: #1791
We're using the `install` argument for configure_file() all over the
place.
The support for an `install` argument for configure_file() was added in
Meson 0.50, but we haven't bumped the minimum version of Meson we
require, yet; which means we're getting compatibility warnings when
using recent versions of Meson, and undefined behaviour when using older
versions.
The configure_file() object defaults to `install: false`, unless an
install directory is used. This means that all instances of an `install`
argument with an explicit `true` or `false` value can be removed,
whereas all instances of `install` with a value determined from a
configuration option must be turned into an explicit conditional.
