`g_app_info_launch_default_for_uri_async()` has already returned by this
point, so waiting a long time is not really going to help.
Wait for 3× as long as the successful case took, which should allow for
long enough to catch true negatives, with a bit of variance.
On my system, this means waiting for about 14ms, rather than the 100ms
which this previous slept for. This speeds the test up by about 5%.

We were generating .desktop files with different content when installed
tests were enabled, and thus making impossible to test some cases
because there was no built file until installed.
To avoid this, always generate both versions of desktop files while
install only the one containing the install path prefix if needed.
Given that it can be computed using an error-prone strings comparisons it
is better to provide a variable everywhere, so that we don't have the
risk of comparing values that are always false.
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.
G_MODULE_SUFFIX is deprecated now because you will get the wrong
results using it most of the time:
1. The suffix on macOS is usually 'dylib', but it's 'so' when using
Autotools, so there's no way to get the suffix correct using
a pre-processor macro.
2. Prefixes also vary in a platform-specific way. You may or may not have
a 'lib' prefix for the name on Windows and on Cygwin the prefix is
'cyg'.
3. The library name itself can vary per platform. For instance, you may
want to load foo-1.dll on Windows and libfoo.1.dylib on macOS. This
is for libraries, not modules, but that is still a use-case that
people use the GModule API for.
g_module_build_path() does take care of (2) on Cygwin, but it
fundamentally cannot handle the possibility of multiple options for
the module name, since it does not do any I/O. Hence, it is also
deprecated.
Instead, g_module_open() has been improved so that it takes care of
all this by searching the filesystem for combinations of possible
suffixes and prefixes on each platform. Along the way, the
documentation for it was also improved to make it clearer what it
does.

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).

The access and creation time tests create a file, gets the time in
seconds, then gets the time in microseconds and assumes that the
difference between the two has to be above 0.
As rare as this may be, it can happen:

Freebsd doesn't always have /proc mounted, so relying on
/proc for the tests isn't ideal.
This commit changes the desktop-app-info tests to use
mkfifo instead of /proc/../fd/.. to relay terminal
arguments.
Might help with this error message I'm seeing in CI:
/tmp/bin-path-H1UQT1/gnome-terminal: cannot create /proc/38961/fd/6: No such file or directory
In case the XDG database is not initialized yet we may try to sniff a
0-length data, making our content-type routines to mark non-empty files
as `application/x-zerosize`.
This is wrong, so in case the sniff size is not set, let's just
try to read the default value. To avoid false-application/x-zerosize
results (that are not something we want as per legacy assumptions).

The implementation of `g_desktop_app_info_launch_uris()` will spawn the
exec file once for each URI unless the desktop file has a placeholder in
its Exec line which supports multiple URIs at once.
The fake terminal doesn’t have such a placeholder, so the fake terminal
script is spawned twice in quick succession, once for each URI. Since it
was making two separate printf calls (one to print the output to the
pipe, and one to terminate it with a newline), it’s possible that two
invocations of the script could interleave their printf calls, resulting
in pipe input along the lines of `URI1 URI2 newline newline` rather than
`URI1 newline URI2 newline`.
This would cause the test to fail.
Fix that by making the script atomic by moving the newline into the
first printf call.

Otherwise, the build will fail when the toolchain is static-only, even
with -Ddefault_library=static. I talked to a Meson developer in their

shared_library is only used if default_library != static.

Check if thumbnails are created in the path we expect and that we can

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.
desktop-app-info test may fail when repeated with multiple concurrent
processes because the actions test relies on checking the existence of
in the shared build directory, so by doing something like:
meson test -C _build desktop-app-info -t 0.3 --repeat 80
We may end up in timeout errors, because we are waiting for files that
have been already deleted by other processes.
To avoid this, let's rely on writing the files on `$G_TEST_TMPDIR` env
variable, that is always set and unique, given that we're using the
G_TEST_OPTION_ISOLATE_DIRS test option.
We were testing the case in which we were opening an actual file, and so
potentially using a fd-list, however we were missing the case in which a file
was not existent.
And in such case we are incidentally hitting a leak now.
All of these warnings indicate programmer error, so critical is most
appropriate here.
Exceptions: deprecation warnings are just warnings. Also, warnings that
are worded with uncertainty can remain warnings rather than criticals.
Enumeration members should either have the name of the type as their
prefix, or they should all have the same prefix.
The "default flags" enumeration member for GApplicationFlags is
unfortunately named G_APPLICATION_FLAGS_NONE, while every other member
of the same type has a G_APPLICATION prefix. The result is that the nick
name of the enumeration member is "flags-none", and that language
bindings will have to use something like
Gio.ApplicationFlags.FLAGS_NONE.
To fix this API wart, we can deprecate the FLAGS_NONE member, and add a
new DEFAULT_FLAGS.
A shell one-liner was enough to set GIO_LAUNCHED_DESKTOP_FILE_PID,
but ideally we also want to do the equivalent of sd_journal_stream_fd()

Ideally we would call sd_journal_stream_fd() in a process that will
exec the real program, otherwise it will report the wrong process ID
in the Journal, but we can't easily do that in a forked child when
using posix_spawn() for subprocesses.

The dominant implementations of the well-known session and system
message buses are the reference implementation from the dbus project
(dbus-daemon) and the sd-bus-based reimplementation dbus-broker, both
of which have correct implementations for EXTERNAL authentication with
an unspecified authorization identity.
This makes it reasonably safe to assume that the well-known message
buses can cope with the unspecified authorization identity, even if we
cannot make the same assumption for custom servers such as the ones
used in ibus and gvfs (which might have been started with an older
GLib version before upgrading GLib in-place).

It doesn't make sense for a proxy resolver to return NULL without an
error on the first call. Whereas a DNS resolver would do this to
indicate that a query completed successfully but found no results, a
proxy resolver should return "direct://" instead. Therefore, if we are
going to return NULL, we ought to have an error as well. Let's make sure
this actually happens by adding some fallback errors just in case
GProxyResolver feeds us weird results.
Additionally, we should not return any errors except
G_IO_ERROR_CANCELLED after the very first iteration. This is an API
contract of GSocketAddressEnumerator. Let's add some checks to ensure
this.
Note that we have inadequate test coverage for GProxyAddressEnumerator.
It's tested here only via GSocketClient. We could do a bit better by
testing it directly as well. For example, I've added tests to see what
happens when GProxyResolver returns both a valid and an invalid URI, but
it's not so interesting here because GSocketClient always uses the valid
result and ignores the error from GProxyAddressEnumerator.
Fixes#2597
This has no practical impact, since it's only a test, and none of the
test code would have hit this bug, but the GTestProxyResolver's check to
see if the URI scheme is simple:// currently only compares the first
four bytes of the string, so it's actually only checking for the "simp"
and would match anything else after that, e.g. "simpleton://". This is
surely not intended.
This was causing intermittent failures on macOS, depending on whether
the tmpdir ended with a `/` or `/some-dir`. `g_strrstr()` is not the
right function to use to extract a basename from a path, for this
