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.
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.
"find-backports" script parses the commit messages to figure out which
patches to backport. We use "refs/notes/bugs" notes to extend the
meta data after the commit was merged. If you don't setup the
notes, the output is likely incomplete or wrong.
Yes, this is annoying. It requires you to setup the notes as described
in "CONTRIBUTING.md". Also because the "release.sh" script runs "find-backports",
so that means you cannot do releases without setting up the notes
(unless you manually disable running "find-backports"). But you really shouldn't
make a release based on incomplete information.
"Ignore-Backport:" is already in use. For the find-backports script it
has the same meaning as a "cherry picked from" line, that means, we
assume that the referenced patch was backported already and the fix
applied.
This is of course useful to make the script shut up about backports that
we don't want to do. However, it requires us to tag the old branch
with this, so that the script thinks that the patch is already there.
Imaging we have a wrong commit on "next" branch with a Fixes line. We
don't want to backport it, so we would have to tag the "old" branch with
"Ignore-Backport:". That is cumbersome.
Instead, now also support that if a commit contains a "Fixes:" line any
an "Ignore-Fixes:" for the same fixed commit, then this let's the
"Fixes:" line be ignored.
This is more for completeness, to go along "nm-code-format.sh"
script.
Usually it's very simple to run black directly (you may still do that).
However, black by default only reformats files with ".py" extension.
So to get all our python files, you'd need to know and explicitly
select them... or use this script.
Also, `black .` scans the entire source tree, and is rather slow.
This script knows which files to select and is thus faster.
When we have a GError* variable on the stack, we usually want to pass
it on to function that can fail. In that case, the variable MUST be
initialized to NULL. This is an easy mistake to make.
Note that this check still can have lots of false positives, for
example, if you have a struct with an GError field. In that case, you
would need to ensure that the entire struct is initialized. Ignore the
warning then.
Also, the check misses if you declare multiple variables on one line.
But that is already discouraged by our style.
There are very few places left where we would accept tabs in a source
file. Warn about that, even if it might cause some false positives.
I think this line was commented out due to a mistake.
The "Ignore-Backport" tag can be used to mark a commit that should not
be backported. Similar to the "cherry picked from" line, which indicates
that the patch was backported.
Anyway, this didn't work correctly, because we first pre-filter the
commits we search (as a performance optimization) by using `git-log` to
get a subset of the commits we want to investigate.
So if you had a commit with an "Ignore-Backport" tag, but without "cherry
picked from" line, then it wasn't found.
Fix that.
Older branches, like "nm-1-32" will always be formatted with a
different, older clang-format version. Luckily we also have on "nm-1-32"
branch the "nm-code-format-container.sh" script, so we can still
reformat the sources using the container.
However, as the name of the container was always "nm-code-format",
we would have to re-generate the container when we switch between
branches. As the container really only depends on the Fedora version
(as the clang-format version is tied to the corresponding Fedora
version), let's include the Fedora version in the name of the container.
We have multiple ways to define properties (like, GVariant based
nm_setting_option_*() or GObject based properties). For the latter,
they nowadays should all be implemented via _nm_setting_property_define_direct_*()
API.
Make checkpatch.pl identify subtree merges in "git am"-formatted
patches and reconstruct the full path names based in the subtree root.
This fixes some spurious warnings for parts of the tree that use
different coding style from what we usually do.

It doesn't actually work inside the root-less container...
Well, it works as far as starting to activate, before it
fails. That is still somewhat useful. So have it there...
The majority of times when I call this script, I want it to do the reformatting,
not the check-only mode. This is also because we use git, so I start with a
clean working directory and run the reformatting code. In the best case, there
is nothing to reformat, and all is good. I seldom want to only check.
Change the default of the script.
"nm-code-format.sh" is going to change the default behavior from "-n" to
"-i", that is, from check-only to reformat. Explicitly pass "-n" where
we want it.
There was always the idea that you could pass paths and filenames
to "nm-code-format.sh" to format only a subset. However, the script
also needs to honor files that should be excluded and don't need
formatting.
Previously, what was implemented via `git ls-files -- ':(exclude)...'`
command, but git-ls-files has a bug ([1]) and might not list all files.
Refactor and do the filtering ourselves.
