Previously, there was very little coverage of GArray behaviour with
either of the zero_terminated or clear_ arguments to g_array_new() set
to TRUE.
Parameterise the tests and exhaustively expand the coverage to cover all
possible GArray configurations.
This was made possible by the online code coverage report for GLib which
we now have:
https://gnome.pages.gitlab.gnome.org/glib/coverage/glib/garray.c.gcov.html.

Previously, g_array_insert_vals() would crash if called with an index
off the end of the array. This is inconsistent with the behaviour of
other methods (like g_array_set_size()), which will expand the array as
necessary.
Modify g_array_insert_vals() to expand the array as necessary. New array
elements will be cleared to zero if the GArray was constructed with
(clear_ == TRUE).

They do both accept NULL value arrays, but only if the number of
elements in the value array is zero. Fix the annotations and mention
this in the documentation.

It's mostly not used anymore and doesn't do what it says it does.
The docs state that it affects GList, GSList, GNode, GMemChunks, GSignal,
GType n_preallocs and GBSearchArray while:
* GList, GSList and GNode use GSlice and are not affected
* GMemChunks is gone
* GType npreallocs is ignored
It also states that it can be used to force the usage of g_malloc/g_free,
which is handled by G_SLICE=always-malloc now.
The only places where it's used is in signal handling through GBSearchArray
and in GValueArray (deprecated). Since it's unlikely that anyone wants to
reduce allocation sizes just for those cases remove the build option.
This test assumes the subprocess does not print anything else on stdout
other than the dbus address, otherwise g_test_trap_assert_stdout()
fails to match. But if the env running tests has G_MESSAGES_DEBUG=all
then it will also print "PATH=%s".
See commit 4c2928a544 for why checking AT_SECURE is preferable compared
to UID checks as currently done in the fallback case.
getauxval() was added with glibc 2.16
While glibc <2.19 didn't provide a way to differentiate a 0 return value from an error,
passing AT_SECURE should always succeed according to
https://sourceware.org/ml/libc-alpha/2014-07/msg00407.html
I've added an errno check anyway, to be on the safe side.
It was added in 4c2928a544 to potentially enable accessing
AT_SECURE through __libc_enable_secure, but was never enabled.
Newer glibc provides getauxval(AT_SECURE) which should be used instead.
Add a TODO note for that.
ENABLE_GC_FRIENDLY_DEFAULT was supposed to set the default for the gc friendliness
while still allowing to force enable it at runtime with G_DEBUG=gc-friendly.
With commit 943a18b564 (6 years ago) things were changed to always set it
according to the content of G_DEBUG in glib_init(), making the default unused.
Since nobody complained since then just remove the macro and the build option.
Try and ensure that people don’t push code with misleading indentation
in future. This should give fairly few false positives.

g_date_strftime() on Windows uses the SYSTEMTIME structure which requires the
year to be >=1601. Passing 1 results in a negative SYSTEMTIME.wYear
which makes GetDateFormatW() fail and crashes due to missing error handling.
Just use 1976 as that's already used a few lines down.
The default `when: on_success` means no artifacts are exported when the
tests fail, which is precisely when we want to see the artifacts.
Always export them, and rely on GitLab to garbage collect them as
appropriate (typically after 30 days, I think).

This means that compilation and test failures will leave logs on the CI
machines which we can use to debug the failures.
Always export the artifacts. The default `when: on_success` is
appropriate for now, but won’t be in future when the tests actual report
their success value correctly.

Add a test macro that allows comparing two floating point values for
equality within a certain tolerance.
This macro has been independently reimplemented by various projects:
* Clutter
* Graphene
* colord
