meson: Get rid of multiline array formatting hack 2025-08-07 02:57:02 +03:00
Graham Christensen
e4f62e4608 Apply clang-format universally.
* It is tough to contribute to a project that doesn't use a formatter,
* It is extra hard to contribute to a project which has configured the formatter, but ignores it for some files
* Code formatting makes it harder to hide obscure / weird bugs by accident or on purpose,

Let's rip the bandaid off?

Note that PRs currently in flight should be able to be merged relatively easily by applying `clang-format` to their tip prior to merge.

flake: Add meson formatter
This adds a meson.format file that mostly mirrors the projects
meson style and a pre-commit hook to enforce this style.
Some low-diff files are formatted.

625dce659a Prepare for FreeBSD sandboxing support
This is the utility changes from #9968, which were easier to rebase
first.

I (@Ericson2314) didn't write this code; I just rebased it.

cc24766fa6 Expose the nix component in header include paths
For example, instead of doing

    #include "nix/store-config.hh"
    #include "nix/derived-path.hh"

Now do

    #include "nix/store/config.hh"
    #include "nix/store/derived-path.hh"

This was originally planned in the issue, and also recent requested by
Eelco.

Most of the change is purely mechanical. There is just one small
additional issue. See how, in the example above, we took this
opportunity to also turn `<comp>-config.hh` into `<comp>/config.hh`.
Well, there was already a `nix/util/config.{cc,hh}`. Even though there
is not a public configuration header for libutil (which also would be
called `nix/util/config.{cc,hh}`) that's still confusing, To avoid any
such confusion, we renamed that to `nix/util/configuration.{cc,hh}`.

Finally, note that the libflake headers already did this, so we didn't
need to do anything to them. We wouldn't want to mistakenly get
`nix/flake/flake/flake.hh`!

Progress on #7876

f3e1c47f47 Separate headers from source files
The short answer for why we need to do this is so we can consistently do
`#include "nix/..."`. Without this change, there are ways to still make
that work, but they are hacky, and they have downsides such as making it
harder to make sure headers from the wrong Nix library (e..g.
`libnixexpr` headers in `libnixutil`) aren't being used.

The C API alraedy used `nix_api_*`, so its headers are *not* put in
subdirectories accordingly.

Progress on #7876

We resisted doing this for a while because it would be annoying to not
have the header source file pairs close by / easy to change file
path/name from one to the other. But I am ameliorating that with
symlinks in the next commit.

46b3188045 Move daemon process into sub-cgroup
The daemon process is now moved into a new sub-cgroup called nix-daemon when the
daemon starts. This is necessary to abide by the no-processes-in-inner-nodes
rule, because the service cgroup becomes an inner node when the child cgroups
for the build are created (see LocalDerivationGoal::startBuilder()).

See #9675

a97a08411c More support for std::filepath in libnixutil
We're not replacing `Path` in exposed definitions in many cases, but
just adding alternatives. This will allow us to "top down" change `Path`
to `std::fileysystem::path`, and then we can remove the `Path`-using
utilities which will become unused.

Also add some test files which we forgot to include in the libutil unit
tests `meson.build`.

28d2af4ea6 Build nix-util with Meson
The idea is two-fold:

- Replace autotools with Meson

- Build each library in its own derivation

The interaction of these two features is that Meson's "subprojects"
feature (https://mesonbuild.com/Subprojects) allows us to have single
dev shell for building all libraries still, while also building things
separately. This allows us to break up the build without a huge
productivity lost.

I tested the Linux native build, and NetBSD and Windows cross builds.

Also do some clean ups of the Flake in the process of supporting new
jobs.

Special thanks to everyone that has worked on a Meson port so far,
@p01arst0rm and @Qyriad in particular.

8f1a26667e add call to checkInterrupt in a bunch of places
This brings back the old behaviour. We check for interrupts in places
that may iterate over wide directories.

`nix::readDirectory` is removed. `std::filesystem::directory_iterator`
is used directly in places that used this util.

c371070580 Use std::filesystem functions in more places
This makes for shorter and more portable code.

The only tricky part is catching exceptions: I just searched for near by
`catch (Error &)` or `catch (SysError &)` and adjusted them to `catch
(std::filesystem::filesystem_error &)` according to my human judgement.

Good for windows portability; will help @siddhantk232 with his GSOC
project.

513634ab5b Make cgroup.{cc,hh} linux-only files
Forcing a conditional include, vs making the headers content
conditional, I think is more maintainable.

It is also how the other platform-specific headers (like
`namespaces.hh`) have been adapted.

02fa20622f Start factoring out Unix assumptions
This splits files and adds new identifiers in preperation for supporting
windows, but no Windows-specific code is actually added yet.
