The Comment field provides a user-visible description of the app,
which usually contains generic words ("and", "or", "not", "is", ...)
that add noise when used for search.
It made some sense to match against the field as a fallback for
Keywords, before that key was well established. However that key
has been around for years now, so hopefully every app where additional
terms are helpful uses it by now.
With that, the downside of added noise outweighs the benefit, so
it's time to stop matching on comments.
POSIX allows dlclose() implementations that are no-ops,
and in such case library destructors run at application
exit rather than dlclose().
That's the case, for example, of UNIX systems with the
Musl LibC.
If you take a release build (--buildtype=release) previously of GLib,
functions such as g_type_create_instance() would call out to
g_type_test_flags() which you can see by disassembling and looking for the
call instruction to <g_type_test_flags> via the library ABI.
Now that the previous commit allows checking abstract and deprecated flags
it makes sense to let the compiler optimize those checks into a single
pass. This is only possible if the functions themselves are inlined.
Additionally, any time we have the same TypeNode we would want to be able
to reuse that node rather than re-locate it.
Every call to g_type_create_instance() currently will incur a RWLock at
least once, but usually twice to test for both G_TYPE_FLAG_ABSTRACT and
G_TYPE_FLAG_DEPRECATED.
Additionally, each call to g_type_instance_free() also checks for these.
That results in a synchronization of GTypeInstance creation across all
threads as well as being a huge amount of overhead when creating instances
like GskRenderNode.
With this patch in place, the next two biggest issues are
g_type_class_ref() and g_type_test_flags() not getting inlined within
gtype.c in release builds. We can address that separately though.
Sysprof shows that the RWLock, with this patch in place, falls off the
profiles.
When setting the file time using utimensat, don't ignore
microseconds for access/modify times. By doing that, they're preserved
when using g_file_info_set_modification_date_time and then setting the file's
attributes from it.

Commit 9e2ad88455 improved app search results by allowing to differentiate
their match_type: prefix match or substring match; while giving more priority
to prefix matches over substring matches, but only when they are in the same
match_category[1].
This was a step forward but, as outlined in #3082, still not enough to get
most relevant results first to the user, because apparently (and for the
specific case of desktop app searching) a prefix match in a lower category
is more relevant to the user than a substring match in a higher category.
So that's what this commit implements, i.e. it makes sure prefix matches
are still preferred over substring matches but this time not only when
in the same category but also across different categories.
[1] Match category is the Desktop file key where the match happened.
They are shown below from top to lesser priority.

· Add a usage output that is printed when called with no argument
or with '--help' argument. This is helpful as it avoids having
to read the source code to know how to run the different options.
· Adds new '--should-show-only' option to 'search' command, to
better mimick the gnome-shell app search, by not returning
apps with NoDisplay=true.
Example for running a desktop app search with the new option from
inside the GLib build dir:
$ gio/tests/apps search --should-show-only settings
This way, the generated GResource code won't choke if no prototypes are found
when being built by clang-cl, which also goes the _MSC_VER >= 1500 route.
Fixes clang-cl build of generated GResources code when building the appstream
git checkout, which supported Windows recently, as the build there demands
'-Werror,-Wmissing-prototypes'.

Make sure to fail consistently in case people created a GPropertyAction
with g_object_new() without passing a property name.
Bindings that construct objects with g_object_new() have no idea if a
property is mandatory.

This avoids a critical warning from trying to disconnect a signal
handler from a `NULL` object if `paction->object` is `NULL` for whatever
reason (see: the following commit).

The `GTK_USE_PORTAL` environment variable has started to be misused by
users, which is causing deployment issues (such as portal services
themselves ending up being forced to use portals, which is never going
to work).
Try and sidestep users’ broken configurations by renaming the
environment variable, and also separating it from the old GTK
environment variable, since the GLib one affects a lot more processes.
This environment variable is meant to be used for
debugging and development, and never in production.
GTK already renamed their environment variable in
https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/4829, so keeping the
`GTK_USE_PORTAL` name in GLib doesn’t make sense anyway.

Fixes: #3107
If glib and PCRE2 are both built for Windows as subprojects of a parent
project, cc.links() will fail because PCRE2 hasn't been built yet when
glib is being configured:
subprojects/glib-2.78.0/meson.build:2109:20: ERROR: Dependencies must be external dependencies
609d58beea changed the detection logic to avoid cc.links() in this
case, but dd5683ce64 broke it again. PCRE2 detection could use a
broader cleanup, but for now, make the minimum change to fix this case.
use_pcre2_static_flag ends up set to false, matching the behavior of
609d58beea.
Fixes: dd5683ce64 ("meson: Allow fallback & static build of pcre subproject")
The introspection parser isn't good enough to expand the shift symbol,
which means G_TYPE_FUNDAMENTAL_MAX is evaluated as (255 << 0).
We can use the `(value)` annotation to force the symbol value in the
introspection data.
