CID 202453 (#1 of 1): Wrong sizeof argument (SIZEOF_MISMATCH)suspicious_sizeof:
Passing argument user_data of type gconstpointer and argument (gsize)nargs * 8UL /* sizeof (gconstpointer) */ to function g_slice_free1 is suspicious.
Let's pass instead the "data" pointer. It's the same, but maybe that
avoids the warning.
(cherry picked from commit d76df4c139)
Coverity doesn't like us ignoring the return value, although
we really only care about the "p" output pointer.
Try casting the result to (void), maybe that silences Coverity.

- don't let no_auto_default_from_file() do any preprocessing of
the lines that it reads. It merely splits the lines at '\n'
and utf8safe-unescapes them.
This was previously duplicated also by NMConfigData's property
setter. We don't need to do it twice.
- sort the lines. This makes the entire handling O(n*ln(n)) instead
of O(n^2). Also, sorting effectively normalizes the content, and
it's desirable to have one true representation of what we write.
In particular when calling nm_utils_strv_sort() with a positive length
argument, then this is not a %NULL terminated strv arrary. That may mean
that it makes sense for the input array to contain %NULL strings.
Use a strcmp() function that accepts %NULL too.
While this is not used at the moment, I think nm_utils_strv_sort()
should accept %NULL strings beause otherwise it's a possibly unexpected
restriction of its API. The function should handle sensible input gracefully.
It is like strcmp(), but has a signature suitable for GCompareDataFunc.
This is necessary with nm_utils_ptrarray_find_binary_search()
to search a sorted strv array.
The fault is here really C, which doesn't allow inline static functions.
So, you need all kinds of slightly different flavors for the same
callbacks (with or without user-data).
Note that glib2 internally just casts strcmp() to GCompareDataFunc ([1]),
relying on the fact how arguments are passed to the function and
ignoring the additional user-data argument. But I find that really
ugly and probably not permissible in general C. Dunno whether POSIX
would guarantee for this to work. I'd rather not do such function
pointer casts.

Usually we avoid GSList, because I think it's not a great data type.
Anyway, our match-specs are just a GSList of strings, so we need some
API to handle them.
We no longer add these. If you use Emacs, configure it yourself.
Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.
No manual changes, just ran commands:
F=($(git grep -l -e '-\*-'))
sed '1 { /\/\* *-\*- *[mM]ode.*\*\/$/d }' -i "${F[@]}"
sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"
Check remaining lines with:
git grep -e '-\*-'
The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.
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.
