libnm-core is also used by the daemon, thus currently dragging in
libnm-crypto there. But could we ever drop that dependency?
One use of the libnm-crypto is in functions like nm_utils_file_is_certificate()
in "nm-utils.h". These are part of the public API of libnm.
But this is not used by the daemon. Move it to "libnm-client-core"
to be closer to where it's actually used.
As we have unit tests in "libnm-core-impl/tests" that test this function,
those unit tests also would need to move to "libnm-client-impl".
Instead, add the actual implementation of these function to "libnm-crypto"
and test it there.
This patch moves forward declarations from public header "nm-utils.h" to
"nm-client.h". Arguably, "nm-client.h" is not a great name, but we don't
have a general purpose header in "libnm-client-public", so use this.
Note that libnm users can only include <NetworkManager.h> and including
individual files is not supported (and even prevented). Thus moving
the declarations won't break any users.
libnm-core currently has a dependency on crypto libraries (either
"gnutls", "nss" or "null"). We need this huge dependency for few cases.
Move the crypto code to a separate static library"src/libnm-crypto/libnm-crypto.la".
The reasoning is that it becomes clearer where we have this dependency,
to use it more consciously, and to be better see how it's used.
We clearly need the crypto functionality in libnm. But do we also need
it in the daemon? Could we ever link the daemon without crypto libraries?
The goal of splitting the crypto part out, to better understand the
crypto dependency.
"nm-error.h" is public API of libnm, and contains error numbers and
quarks. Clearly our "nm-crypto" implementation wants to use those
errors.
I want to move "nm-crypto" out of libnm, and as it's more basic, I think
it should not have a dependency on all of libnm-core. Also because
libnm-core currently uses nm-crypto, so there would be a circular
dependency. Which would be possible to do (libnm-core-aux-intern is
also used in such a way). But it's better avoided, to have clear
hierarchy of dependencies.
Add a version of the same error codes to libnm-base. libnm-base is a
very basic dependency (just one step above libnm-glib-aux).
We use clang-format for automatic formatting of our source files.
Since clang-format is actively maintained software, the actual
formatting depends on the used version of clang-format. That is
unfortunate and painful, but really unavoidable unless clang-format
would be strictly bug-compatible.
So the version that we must use is from the current Fedora release, which
is also tested by our gitlab-ci. Previously, we were using Fedora 34 with
clang-tools-extra-12.0.1-1.fc34.x86_64.
As Fedora 35 comes along, we need to update our formatting as Fedora 35
comes with version "13.0.0~rc1-1.fc35".
An alternative would be to freeze on version 12, but that has different
problems (like, it's cumbersome to rebuild clang 12 on Fedora 35 and it
would be cumbersome for our developers which are on Fedora 35 to use a
clang that they cannot easily install).
The (differently painful) solution is to reformat from time to time, as we
switch to a new Fedora (and thus clang) version.
Usually we would expect that such a reformatting brings minor changes.
But this time, the changes are huge. That is mentioned in the release
notes [1] as
Makes PointerAligment: Right working with AlignConsecutiveDeclarations. (Fixes https://llvm.org/PR27353)

Give a consistent name.
A bit odd are now the names nm_g_bytes_hash() and nm_g_bytes_equal()
as they go together with nm_pg_bytes_hash()/nm_pg_bytes_equal().
But here the problem is more with the naming of "nm_p*_{equal,hash}()"
functions, which probably should be renamed to "nm_*_ptr_{equal,hash}()".
"nm-test-utils.h" is a header-only, helper library for our unit tests.
It was somewhat unmotivated in "shared/nm-utils", because all tests use
it, but it was not part of a "module".
Move it to "src/libnm-glib-aux/". It fits there very well. They both
have (only) a dependency on glib.
"libnm-core/" is rather complicated. It provides a static library that
is linked into libnm.so and NetworkManager. It also contains public
headers (like "nm-setting.h") which are part of public libnm API.
Then we have helper libraries ("libnm-core/nm-libnm-core-*/") which
only rely on public API of libnm-core, but are themself static
libraries that can be used by anybody who uses libnm-core. And
"libnm-core/nm-libnm-core-intern" is used by libnm-core itself.
Move "libnm-core/" to "src/". But also split it in different
directories so that they have a clearer purpose.
The goal is to have a flat directory hierarchy. The "src/libnm-core*/"
directories correspond to the different modules (static libraries and set
of headers that we have). We have different kinds of such modules because
of how we combine various code together. The directory layout now reflects
this.
