Our GObject structs should be internal API. In which case, we should
embed the private data in the struct themselves (`_priv`) and use the
_NM_GET_PRIVATE() macro. The advantage is better debugability because
following G_TYPE_INSTANCE_GET_PRIVATE() in the debugger is very
cumbersome. Another (less relevant) advantage is better performance.
Thus, warn about uses of g_type_class_add_private() and
G_TYPE_INSTANCE_GET_PRIVATE().
Note that if the struct and is in a header file (which is usually only
necessary when subclassing the type), then the private data should be
an opaque pointer `_priv` instead, and we should use the _NM_GET_PRIVATE_PTR()
macro. In that case, the use of g_type_class_add_private() and
G_TYPE_INSTANCE_GET_PRIVATE() is correct and the warning is false. But
this is only a warning, for the unusual case where we have deep object
hierarchies.

"-u" calls `git diff -name-only $UPSTREAM` to get a list of files.
However, if $UPSTREAM contains a file that doesn't exist in the current
checkout, we get a non-existing file name and clang-format will fail.
Avoid that, by filtering only files that exist.
Also, pass "--no-renames" option to git-diff.
Reformatting the entire source tree takes quite long. For fast
development it's useful to only check the files that changes on the
current checkout.
For that there was already the "-F|--fast" option, but that only
compared the files that changed compared to HEAD^.
What actually would be useful is to check the files that changed on the
current branch, compared to some upstream commit. Add "-u|--upstream"
option to specify the upstream commit (usually "main").
As a special twist,
./contrib/scripts/nm-code-format.sh -u
is the same as
./contrib/scripts/nm-code-format.sh -u main
We need to mount sysfs, so that `ip netns exec` works.
Do that automatically when starting the system container, via rc.local.
While at it, use `podman build --squash-all` to speedup the building of
the container image.
It's between "stop" and "clean". It removes the container,
but keeps the container images. This is to fast restart without
rebuilding the container (image).
- instead of g_str_hash()/g_direct_hash(), use our own functions
nm_str_hash()/nm_direct_hash(). Those use siphash24 with a random
seed.
- don't pass g_direct_equal() to GHashTable. When omitting the equal
function, it falls back to direct pointer comparison, which is likely
faster. In any case, it's consistent to not use g_direct_hash()
when using pointer equality.
- instead of g_int_hash()/g_int64_hash()/g_double_hash(), use
our nm_pint_hash()/nm_pint64_hash()/nm_pdouble_hash(). The latter
two don't exist yet.
The reason is that we want to use siphash24.
Yes, our name differs from glib's. Our naming seems to make sense
to me however, because we also have nm_pstr_hash(), nm_pdirect_hash()
and even nm_ppdirect_hash() for following the pointers. Naming is hard.
- instead of g_int_equal()/g_int64_equal()/g_double_equal() use
our nm_pint_equal()/nm_pint64_equal()/nm_pdouble_equal(). The latter
two don't exist yet. The reason is purely naming consistency since
our hash variants follow the other name.
Leave a hint about core-dumps.
Also, now we have `contrib/fedora/rpm/configure-for-system.sh` script,
which can configure the build in a way similar to what we get
when doing an RPM build.
That means, inside "contrib/scripts/nm-in-container.sh" we
can just type `make install`, and it will replace the pre-installed
NetworkManager.
The main advantage is that it becomes convenient to run NetworkManager
as a systemd service. Previously, the suggested was to to install
NetworkManager inside another prefix, and run it in the terminal.
Running NetworkManager as systemd service is also necessary for NM-ci,
which restarts the NetworkManager service, and you couldn't run a test,
if you just started NetworkManager in a terminal.
Previously, you had to build a complete RPM, which takes a lot of time.
Yes, it's a large dependency. But on your outer host you
probably configured NetworkManager with QT enabled (for the
example scripts). We want to compile the same work tree inside
the container. So install qt-devel.
This will use the same option as when we do an RPM build.
The purpose is that you could type `make install` with such
a build, and it would replace the files that you'd get by installing
the NetworkManager RPMs.
Of course, you would not want to do that on your work station, but it
will be useful in a container, where we don't mind messing up the
installation.
autotools accepts both --with-$OPTION/--without-$OPTION and
--with-$OPTION=yes|no. Consistently use the latter.
The advantage is that whether it's enabled becomes an argument, so in a
script you could do
"--with-$OPTION=$VALUE"
Same for enable/disable option.
The test bcond is used to make test suite failure terminate the %check
phase. That should generally be done for distro builds.
What the distro builds shouldn't do is terminate the build on compiler
warnings, because they're fairly likely to appear on toolchain updates
without indicating actual bugs.
However, currently that's precisely what do we do now.
Let's use -Werror on debug builds instead. They are intentionally made
more prone to fail (e.g. trip more runtime assertions) because failures
can be more rapidly addressed and don't affect distro builds.
Resolve the defaults in build.sh instead of RPM macros. This looks less
terrible maintaining the same defaults as well as options to override it
upstream.
Moving it to the block that downstreams (Fedora, Red Hat) keep
customized makes it possible for them to also maintain customized
defaults here.
In particular, the downstreams should be able to enable bcond_test
at least for their production release (otherwise there's little point in
actually running tests at package build time).

Otherwise, the path "src/c-stdaux/src/docs/conf.py" matches for
formatting. But this file is imported via git-subtree, we don't
want to format it.
Filter out such paths.
Recent gettext version can extract and merge back strings from and to
various file formats, no need for intltool anymore.

Clarification about the use of AM_GNU_GETTEXT_REQUIRE_VERSION:
In configure.ac, specify the minimum gettext version we require, rather
than the exact one. This fixes a situation where the autoconf macros
used for gettext will be the latest available on the system (for
example, 0.20); but the copied-in Makefile.in.in will be for the exact
version specified in configure.ac (in this case, 0.19).
In that situation, the gettext build rules will error out at `make` time
with the message:
*** error: gettext infrastructure mismatch: using a Makefile.in.in
from gettext version 0.19 but the autoconf macros are from gettext
version 0.20
Avoid that by specifying a minimum version dependency rather than an
exact one. This should not cause problems as we haven’t committed any
generated or external gettext files into git, so each developer will end
up regenerating the build system for their system’s version of gettext,
as expected.
See the subsection of
https://www.gnu.org/software/gettext/manual/html_node/Version-Control-Issues.html
for more information.
Note that autoreconf currently doesn’t recognise
AM_GNU_GETTEXT_REQUIRE_VERSION, so we must continue also using
AM_GNU_GETTEXT_VERSION. autopoint will ignore the latter if the former
is present. See
https://lists.gnu.org/archive/html/autoconf-patches/2015-10/msg00000.html.
[lkundrak@v3.sk: Fixed the meson build, adjusted autogen.sh:
droped "|| exit 1", dropped call to aclocal,
dropped --copy from gtkdocize.]
Apt is run for each package separately and errors are ignored. This is
not great -- it's slow and ignores errors. Therefore we sometimes end
up without packages we need.
Let's tolerate errors only for packages that we are know can fail to
install safely.
It's just convenient to have some tools around, not only
for testing, but also for (some limited) development.
In particular, because we bind-mount .vimrc inside the container, and
if I use vim, black/clang-format is just one key binding away.
You can of course just clone NetworkManager repository and start hacking
as you like. However, there are a few things like git-notest which are
interesting to setup.
Add a script to do this.
The script is supposed to be idempotent and do nothing, unless
necessary. By default it also only prints what it would do.
NetworkManager does not support by default legacy ifcfg configuration
files anymore, this support is now provided in a separate package
(https://fedoramagazine.org/converting-networkmanager-from-ifcfg-to-keyfiles/).
ifcfg directory (/etc/sysconfig/network-scripts/) should always be present,
regardless of NetworkManager support for network scripts. This change makes the
directory always present, not only when the recently splitted ifcfg subpackage
is installed, and also make it persistent after the package removal.
