Having G_PID_FORMAT macro is useful, but it's only available in
recent glib versions. Add a compat implementation and a test that
our assumptions hold.
nmtst_get_rand_int() was originally named that way, because it
calls g_rand_int(). But I think if a function returns an uint32, it
should also be named that way.
Rename.
These tests cannot (easily) be under "shared/nm-libnm-core-aux/tests"
because libnm/libnm-core requires code under shared while
"nm-libnm-core-aux" requires libnm/libnm-core. With autotools that is
not problem, but with meson we include sub directories in a particular
order and there is no way to foward declare stuff (AFAIK). To avoid
the circular dependency, add the tests to "clients/common/tests", which
is always built last.
From the files under "shared/nm-utils" we build an internal library
that provides glib-based helper utilities.
Move the files of that basic library to a new subdirectory
"shared/nm-glib-aux" and rename the helper library "libnm-core-base.la"
to "libnm-glib-aux.la".
Reasons:
- the name "utils" is overused in our code-base. Everything's an
"utils". Give this thing a more distinct name.
- there were additional files under "shared/nm-utils", which are not
part of this internal library "libnm-utils-base.la". All the files
that are part of this library should be together in the same
directory, but files that are not, should not be there.
- the new name should better convey what this library is and what is isn't:
it's a set of utilities and helper functions that extend glib with
funcitonality that we commonly need.
There are still some files left under "shared/nm-utils". They have less
a unifying propose to be in their own directory, so I leave them there
for now. But at least they are separate from "shared/nm-glib-aux",
which has a very clear purpose.
(cherry picked from commit 80db06f768)
"shared/nm-utils" contains general purpose utility functions that only
depend on glib (and extend glib with some helper functions).
We will also add code that does not use glib, hence it would be good
if the part of "shared/nm-utils" that does not depend on glib, could be
used by these future projects.
Also, we use the term "utils" everywhere. While that covers the purpose
and content well, having everything called "nm-something-utils" is not
great. Instead, call this "nm-std-aux", inspired by "c-util/c-stdaux".
(cherry picked from commit b434b9ec07)
Supporting a trailing comma in NM_MAKE_STRV() can be desirable, because it
allows to extend the code with less noise in the diff.
Now, there may or may not be a trailing comma at the end.
There is a downside to this: the following no longer work:
const char *const v1[] = NM_MAKE_STRV ("a", "b");
const char *const v2[3] = NM_MAKE_STRV ("a", "b");
but then, above can be written more simply already as:
const char *const v1[] = { "a", "b", NULL };
const char *const v2[3] = { "a", "b" };
so the fact that the macro won't work in that case may be preferable,
because it forces you to use the already existing better variant.
"shared/nm-utils" is a loose collection of utility functions.
There is a certain aim that they can be used independently.
However, they also rely on each other.
Add a test that we can build a minimal shared library with
these tools, independent of libnm-core.
