It can cause failures for shared connection objects.
What can currently happen is this:
1. A user starts to asynchronously create a proxy object
2. A user starts to asynchronously create another proxy object
At this point, the asynchronous initialization for the two proxy objects
share the not yet initialized connection object.
3. While the shared connection objected is created, the user cancels the
creation with the supplied cancellable from the fist proxy object.
4. initable_init caches the canceled error and marks the connection as
initialized.
5. The initialization of the second proxy object fails with the same
canceled error.
To avoid this, clear the error in this case and destroy any member
variables that may have been created before the creation was canceled.
This way, the initialization of the second proxy object will restart the
connection initialization and with probably succeed.

GDBus has always supported matching strings with arg0 matching
(`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH`). In D-Bus 1.5, support was added
to the spec for also matching object paths. This got forgotten about and
was never added to GDBus, meaning that
`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH` won’t match against a signal arg0
of type `o`.
Fix that, and add a unit test.
To do so, we need to add a new `g_dbus_message_get_arg0_path()` API to
complement the existing `g_dbus_message_get_arg0()` API. The approach of
letting `g_dbus_message_get_arg0()` return an object-path *or* a string
would not work, as it’s also called in the implementation of
`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_NAMESPACE`, which must only match
string-typed arg0 values and not object-path-typed ones.

Depending on the operating system, /bin/sh might either be bash (for
example on Fedora or Arch) or dash (for example on Debian or Ubuntu)
or some other POSIX shell.
When bash is asked to run a simple command with no shell keywords or
metacharacters, like this one, it replaces itself with the program
via execve(), but dash does not have that optimization and treats it
like any other program invocation in a larger script: it will fork,
exec the program in the child, and wait for the child in the parent.
This seems like it conflicts with sleep_and_kill() assuming that it can
use the subprocess's process ID as the sleep(1) process ID. Specifically,
if it sends SIGKILL, it will go to the sh(1) process and not the sleep(1)
child, which could result in the sh(1) process being terminated and
its sleep(1) child being leaked.
To get the bash-like behaviour portably, explicitly use the exec builtin
to instruct the shell to replace itself with sleep(1), so that the
process ID previously used for the shell becomes the process ID of the
sleep process.
This appears to resolve an intermittent hang and test timeout on Debian
machines (especially slower ones), although I'm not 100% clear on the
mechanics of how it happens.

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.
When setting the file time using utimensat, don't ignore

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.

It's not safe to use setlocale() to mutate the locale in a threaded
program. Lots of other tests still do this, and I'm not putting in the
effort to fix them comprehensively in the absense of actual failures on
CI, but I figured it'd be good to fix the tests that I was touching.
This definitely does not do anything on Linux. I bet it's not needed on
other platforms, either. It's unsafe and may crash; there is no safe way
to mutate the environment in threaded programs.
This is a copy of the existing test_l10n, modified to use LC_TIME
instead of LC_MESSAGES. It's not safe as each call to g_setenv() or
setlocale() could cause the test to crash; there is no safe way to
change a threaded process's environment, and a threaded process's locale
can only be safely changed using uselocale(), not with setlocale().
The calls to g_setenv() are definitely not needed on Linux. I wonder
whether removing these will break the test on other platforms?
The calls to setlocale() should be replaced by a dance of
uselocale() -> duplocale() -> newlocale() -> uselocale() on Linux. But
this is not portable and this is a cross-platform test. We would have to
make the test platform-specific to do this. macOS and at least FreeBSD
provide these functions via xlocale.h, but this isn't portable.
The test was passing fine when `bindir` was equal to `multiarch_bindir`,
but not when they differ.
For example, on a Debian system, `gio-querymodules` is installed to
`/usr/lib/x86_64-linux-gnu/glib-2.0/gio-querymodules` rather than
`/usr/bin/gio-querymodules` as it is on (say) Fedora.

Avoid generating more code than needed, so other than continuing using
the generic glib marshallers when possible, define once the custom ones
we need for each file we generate.
The marshallers are then re-used across all the interfaces defined
without duplicating the code size.
This is the same we're doing in code generated by glib-genmarshaller and
what gmarshal does internally.
Since the generated gdbus C code can be considered private too, this is
safe to do, and will allow faster access to GValue objects.
Get rid completely of the usage of the generic marshaller in gdbus
generated code, using instead specific marshallers.
Code is not yet optimized fully since we may still have duplicated
functions to be generated.

We relied on g_cclosure_marshal_generic() to easily generate signal

Given that we know the types we work on, it's easy enough to generate
the marshallers ourself.

As explained in the previous commit, GNU Coreutils 9.2 changes the behaviour
of `du --bytes` to only count regular files and symlinks.
The previous commit makes the test pass with GNU Coreutils >=9.2, but the
machine running the tests may have an older version, or perhaps even a
reimplementation such as uutils. So we can't rely on the size returned by `du`
to be the consistent across systems any more.
However, the plus side of the new behaviour is that the size reported by `du`
/ `G_FILE_MEASURE_APPARENT_SIZE` is now well-defined across filesystems
(as the sum of the sizes of regular files & symlinks), so we can hardcode it.

As you can see from the error message it can't infer the target
architecture (you need a least one valid .o file or the -m flag).
If you use the compiler instead of directly invoking the linker it will
pass the appropriate flags:
```
$ ~/cheri/output/sdk/bin/clang -r -Wl,-b,binary gio/tests/test5.gresource -o gio/tests/test_resources.o -v

```
This works for most architectures, but ones that need additional metadata
sections to encode the used ABI, etc. will require a different approach
using .incbin. However, that is a change for another MR.

In case the OS does not support epoll and kqueue, we get the warning:
gio/tests/pollable.c: In function ‘test_pollable_unix_nulldev’:
gio/tests/pollable.c:266:7: warning: unused variable ‘fd’
[-Wunused-variable]
266 | int fd;
Get rid of it.

Fix the tests, by allocating the structure.

There’s a kernel bug on the CI machines which is causing this test to
fail all the time and it’s getting my goat.
The test can be re-enabled later (by reverting this commit) when the
kernel on the CI VM host is fixed. I don’t know when that’s going to
happen.
