The flake for pre-commit-checks is rather questionable. We ignored
it so it uses our own nixpkgs and doesn't reimport nixpkgs. This should
save a couple of seconds of eval time!

package.nix previously needed this callPackage'd externally, which
didn't make a lot of sense to us since this is an internal dependency.
Thus we changed it to make it more self contained.

Although these are not like, super critical tests, we would like to

The following command is now sufficient to build Lix from outside of the

In our view it really doesn't make sense to not have this in in
package.nix in some way. These patches aren't just for performance or
something -- Lix flat out doesn't build without these patches.
(Arguably that makes them a buildsystem responsibility as well, but that
can wait for when we're ready to start adding subproject fallback
dependency resolution to Meson.)
This is a step towards making `package.nix` more self-sufficient and
`callPackage`able without excessive external logic.
With this change the following command is enough to build Lix from out
of the flake:
nix-build -E 'let pkgs = import <nixpkgs> { }; in pkgs.callPackage
./package.nix { build-release-notes = false; inherit (pkgs.lib) fileset;
nix-doc = pkgs.callPackage ./nix-doc/package.nix { }; }'

For a long time `nix repl` has supported displaying documentation set on
builtins, however, it has long been convention to use Markdown comments
on Nix functions themselves for documentation. This exposes that
information to `nix repl` users in a nice and formatted way.
NixOS/rfcs#145 doc-comments are primarily what this feature is intended
to consume, however, support for lambda documentation in the repl is
experimental. We do our best effort to support the RFC here.

I didn't enable this by default for clang due to making the build time
10% worse or so. Unfortunate, but tbh devs for whom 10% of build time is
not *that* bad should probably simply enable this.

hacking changelog-d to support not just github but also forgejo and
gerrit is a lot more complicated than it's worth, even moreso since
the entire thing can just as well be done with ~60 lines of python.
this new script is also much cheaper to instantiate (being python),
so having it enabled in all shells is far less of a hassle.
we've also adjusted existing release notes that referenced a gerrit
cl to auto-link to the cl in question, making the diff a bit bigger

This commit adds several meson.build, which successfully build and
install Lix executables, libraries, and headers. Meson does not yet
build docs, Perl bindings, or run tests, which will be added in
following commits. As such, this commit does not remove the existing
build system, or make it the default, and also as such, this commit has
several FIXMEs and TODOs as notes for what should be done before the
existing autoconf + make buildsystem can be removed and Meson made the
default. This commit does not modify any source files.
A Meson-enabled build is also added as a Hydra job, and to
`nix flake check`.

This series takes a somewhat different approach from the flake rework
done in NixOS/nix. The package.nix here does not provide callPackage
options for all the various settings in the build, and instead the other
places Nix derivations are used (like internal-api-docs) will .overrideAttrs
the normal Nix package derivation. This more closely matches how these
things were structured originally, and results in less churn and more
atomicity in these changes.
In the future, package.nix likely will migrate to have more build
options in the callPackage arguments, but we are also planning to
rewrite the build system anyway.

deduplication does not currently work fully, showing derivations
multiple times if they have different underlying values. this can happen
by selecting the same derivation twice for two different attributes of a
set, using inherit-from (which reduces to the previous), importing
nixpkgs twice, or any other number of things.
since users already have to deal with duplicates for this reason it
won't hurt to add *more* duplicates. the alternative would be to
deduplicate fully, which would drop derivations that are currently
returned and those pose a regression risk.

Just `stdenv.isDarwin` isn't enough because it doesn't apply to the
build platform, which mean that cross packages building from darwin to
another platform will have `isDarwin` set to false.
Replace it by `stdenv.buildPlatform.isDarwin`.

Today, with the tests inside a `tests` intermingled with the
corresponding library's source code, we have a few problems:
- We have to be careful that wildcards don't end up with tests being
built as part of Nix proper, or test headers being installed as part
of Nix proper.
- Tests in libraries but not executables is not right:
- It means each executable runs the previous unit tests again, because
it needs the libraries.
- It doesn't work right on Windows, which doesn't want you to load a
DLL just for the side global variable . It could be made to work
with the dlopen equivalent, but that's gross!
This reorg solves these problems.
There is a remaining problem which is that sibbling headers (like
`hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end
up shadowing each other. This PR doesn't solve that. That is left as
future work for a future PR.

I think it is bad for these reasons when `tests/` contains a mix of
functional and integration tests
- Concepts is harder to understand, the documentation makes a good
unit vs functional vs integration distinction, but when the
integration tests are just two subdirs within `tests/` this is not
clear.
- Source filtering in the `flake.nix` is more complex. We need to
filter out some of the dirs from `tests/`, rather than simply pick
the dirs we want and take all of them. This is a good sign the
structure of what we are trying to do is not matching the structure
of the files.
With this change we have a clean:
```shell-session
$ git show 'HEAD:tests'
tree HEAD:tests
functional/
installer/
nixos/
```

Interface has changed upstream.
It *should* be fine to test 23.05's other Nix versions as those
*should* succeed, but that's not the case and it's obfuscating
our terrible CI setup's log.
Source filtering is a really cool Nix feature that lets us avoid a
lot of rebuilds, which speeds up the iteration cycle a lot in cases
where the relevant source files aren't actually modified.
We used to have a source filter that marked a few files as irrelevant,
but this is the wrong approach, as we have many more files that are
irrelevant. We may call this negative filtering.
This commit switches the source filtering to positive filtering, which
is a lot more robust. Instead of marking which files we don't need
we marked the files that we do need.
It's a superior approach because it is fail safe. Instead of allowing
build performance problems to creep in over time, we require that all
source inputs are declared.
I shouldn't have to explain that declaring inputs is a good practice,
so I'll stop over-explaining here.
I do have to acknowledge that this will cause a build failure when the
filter is incomplete. This is *good*, because it's the only realistic
way we could be reminded of these problems. These events will be
infrequent, so the small cost of extending the filter is worth it,
compared to the hidden cost of longer dev cycles for things like tests,
docker image, etc, etc.
(Also rebuilding Nix for stupid unnecessary reasons makes my blood boil)
Previously, for tarball flakes, we recorded the original URL of the
tarball flake, rather than the URL to which it ultimately
redirects. Thus, a flake URL like
http://example.org/patchelf-latest.tar that redirects to
http://example.org/patchelf-<revision>.tar was not really usable. We
couldn't record the redirected URL, because sites like GitHub redirect
to CDN URLs that we can't rely on to be stable.
So now we use the redirected URL only if the server returns the
`x-nix-is-immutable` or `x-amz-meta-nix-is-immutable` headers in its
response.
Currently it gives a 500 error with "Do not know how to serve path
'/nix/store/bym5sm8z2wpavnvzancb9gjdlgyzs1l8-nix-internal-api-docs-2.15.0pre20230320_e37f436/share/doc/nix/internal-api'."
The motivation is as stated in issue #7814: even though the the C++ API
is internal and unstable, people still want it to be well documented for
sake of learning, code review, and other purposes that aren't predicated
on it being stable.

This was failing because the check for the existence of the
'installcheck' target failed silently, so the whole phase got
skipped. It works by running 'make -n installcheck 2> /dev/null',
which however barfs with
/nix/store/039g378vc3pc3dvi9dzdlrd0i4q93qwf-binutils-2.39/bin/ld.gold: error: cannot open tests/plugins/plugintest.o: No such file or directory
Fixes#8004.
Building without tests is useful for bootstrapping with a smaller footprint
or running the tests in a separate derivation. Otherwise, we do compile and
run them.
This isn't fine grained as to allow picking `check` but not `installcheck`
or vice versa, but it's good enough for now.
I've tried to use Nixpkgs' `checkInputs`, but those inputs weren't discovered
properly by the configure script. We can emulate its behavior very well though.
Some dependencies supposed to be skipped in the cross build, along with
not using the gold linker. But in https://github.com/NixOS/nix/pull/6538
this was accidentally not preserved.
Also since https://github.com/NixOS/nix/pull/6538 we saw some new
aarch64-linux static build failures. This is a first attempt to try to
fix those failures. If this is not sufficient, there are other things we
can try next.
- `nixpkgsFor` does all of native, static, cross, and the different stdenvs.
- The main Nix derivation is no longer duplicated for static.
- DRY nixpkgs.lib and lib.genAttrs calls.
- Refer to current version in readme
- Split into flakes and non-flakes section
- Change order to move nix-build to the end, since people often start
with it in the beginning.
- Use proper "Note" syntax
- Add notes about editor integration
- Move information about target platforms and stdenvs into separate
sections

The issue *seems* to be the cross jobs, which are missing the `CXXFLAGS`
needed to get rapidcheck.
PR #6538 would be really nice to resurrect which will prevent the
`configureFlags` from going out of sync between the regular build and
the cross build again.
