for a discussion on if/when we can start relying on Python 3 only.
Use Python 3.4 as a new requirement because that's the version used in
SLES 12 and Debian 8 and there is no good reason to require something newer
right now.
The new python module, added with 0.46, works with Python 2 and 3 and
allows to pass a path for the interpreter to use, if the need arises.
Previously the meson build set PYTHON, used in the shebang line of
the scripts installed by glib, to the full path of the interpreter.
The new meson module doesn't expose that atm, but we should set it to
a executable name anyway, and not a full path.
Several of our tools are installed and are used by other projects to
generate code. However, there is no 'install' when projects use glib
as a subproject.
We need some way for glib to 'provide' these tools so that when some
project uses glib as a subproject, find_program('glib-mkenums') will
transparently return the glib-mkenums we just built.
Starting from Meson 0.46, this can be done with the
`meson.override_find_program()` function.
As a bonus, the Meson GNOME module will also use these
'overriden'/'provided' programs instead of looking for them in PATH.
These tests will work if the glibc translations are up to date, or if
the GLib translations are installed and up to date; but not if neither
are in place.

Type punning is used on the existing implementation, which hides errors
such as:
GSList *list = NULL;
g_clear_pointer (&list, g_error_free);
Let's use __typeof__ to cast the passed-in pointer before it's passed to
the free function so it trips -Wincompatible-pointer-types if it's wrong.
Fixes#1425
PEP8 says that:
"Comparisons to singletons like None should always be done with is or
is not, never the equality operators."
glib uses a mix of "== None" and "is None". This patch changes all
cases to the latter.
The implementation is silently discarding this anyway, and
g_object_unref() is using atomic operations. So this should be safe.
Having this here triggers -Wdiscarded-qualifiers when g_clear_pointer()
is fixed to use __typeof__().
If G_DISABLE_ASSERT is defined, g_assert() is a no-op. Despite it now
being standard practice to *not* use g_assert() in unit tests (use
g_assert_*() instead), a lot of existing unit tests still use it.
Compiling those tests with G_DISABLE_ASSERT would make them silently
no-ops. Avoid that by warning the user loudly.
Note that it’s pretty rare for people to compile with G_DISABLE_ASSERT,
so it’s not expected that this will be hit often.
