This is purely to let Cargo's dependency resolver do stuff for us, we do
not actually intend to build this stuff with Cargo to begin with.

lix-doc is now built with Meson, with lix-doc's dependencies built as
Meson subprojects, either fetched on demand with .wrap files, or fetched
in advance by Nix with importCargoLock. It even builds statically.
Fixes#256.

The <() process substitution syntax doesn't work for this one testcase
in bash for FreeBSD. The exact reason for this is unknown, possibly to
do with pipe vs file vs fifo EOF behavior. The prior behavior was this
test hanging forever, with no children of the bash process.

Closes#460
I managed to trigger the issue by having the following inputs (shortened):
authentik-nix.url = "github:nix-community/authentik-nix";
authentik-nix.inputs.poetry2nix.inputs.nixpkgs.follows = "nixpkgs";
When evaluating this using
nix-eval-jobs --flake .#hydraJobs
I got the following error:
error: cannot update unlocked flake input 'authentik-nix/poetry2nix' in pure mode
The issue we have here is that `authentik-nix/poetry2nix` was written
into the `overrideMap` which caused Nix to assume it's a new input and
tried to refetch it (#460) or errored out in pure mode
(nix-eval-jobs / Hydra).
The testcase unfortunately only involves checking for the output log
and makes sure that something *is* logged on the first fetch so that
the test doesn't rot when the logging changes since I didn't
manage to trigger the error above with the reproducer from #460. In
fact, I only managed to trigger the `cannot update unlocked flake input`
error in this context with `nix-eval-jobs`.

this can be a proper WorkResult now. childTerminated is unfortunately a
lot more stubborn and won't be made private for quite a while yet. once
we can get rid of the Worker poll loop that *should* be possible though

we'll need this once we want to pass extra information out of accepting
replies, such as fd sets or possibly even async output reader promises.

don't keep fds open we're not using. currently this does not cause any
problems, but it does increase the size of our fd table needlessly and
in the future, when we have proper async processing, having builderOut
open in the daemon once the hook has been fully started is problematic
Change-Id: I6e7fb773b280b042873103638d3e04272ca1e4fc
this is useless to do on the face of it, but it'll make it easier to
convert the entire output handling to use async io and promises soon

only DerivationGoal can set the hook to anything at all. it always sets
buildOutFD to something that is not related to fromHook in any way, and
mixing the two would have rather dire consequences for log consistency.

This is incredibly haunted, but it can happen that you change libutil,
breaking the generation of the .json files, which then does not rebuild
the files. I don't expect they are slow to build, so it does not seem so
bad to just rebuild them every time instead of extracting a list of all
the possible deps.
We want to delete this nonsense anyway and replace it with generated
code.

all derivation goals need a log fd of some description. let's save this
single fd in a dedicated pointer field for all subclasses so that later
we have just the one spot to change if we turn this into async promises

we don't need to expose information about how busy a Worker is if the
worker can instead tell its work items whether they are in a slot. in
the future we might use this to not start items waiting for a slot if
no slots are currently available, but that requires more preparation.

They are like experimental features, but opt-in instead of opt-out. They
will allow us to gracefully remove language features. See #437

The target_machine variable is meant for the target
of cross compilers. We are not a cross compiler, so
instead reuse our host_machine based checks.
Fixes Linux→FreeBSD cross, since Meson can't figure
out `target_machine.kernel()` in that case.

For years both the documentation and nixpkgs have said that CppNix is
LGPL-2.1-or-later, not LGPL-2.1-only as is somewhat implied by the
README. We are choosing to update the README to match the rest of the
references.

Seems a little bit Rich that musl does not implement close_range because
they suspect that the system call itself is a bad idea, so they uhhhh
are considering not implementing a wrapper. Let's just fix the problem
at hand by writing our own wrapper.

Turns out strings do not like being resized to -4.
This was discovered while messing with the tests to remove unbuffer and
trying stdbuf instead. Turns out that was not the right approach.
This basically rewrites the handling of this case to be much more
correct, and fixes a bug where with small window sizes where it would
ALSO truncate the attr names in addition to the optional descriptions.

I was packaging Lix 2.91 for nixpkgs and was annoyed at the expect
dependency. Turns out that you can replace unbuffer with a pretty-short
Python script.
It became less short after I found out that Linux was converting \n to
\r\n in the terminal subsystem, which was not very funny, but is at
least solved by twiddling termios bits.

This will stop printing stuff to dumb terminals that they don't support.
I've overall audited usage of isatty and replaced the ones with intent
to mean "is a Real terminal" with checking for that. I've also caught a
case of carelessly assuming "is a tty" means "should be colour" in
nix-env.

I noticed there was some stuff setting configureFlags that definitely do
not do anything with meson, so let's rip them out.
As for the empty file, it was added when I was thinking I needed a fake
C++ target to convince meson to create the necessary dependencies. That
was not in fact possible so it should have never been committed.

We're going for Dragon's Breath because horrors called dibs on it.
It's fine to merge this a little before the final release, since all the
dev versions have -pre in them anyway.

this is only used to close non-stdio files in derivation sandboxes. we
may as well encode that in its name, drop the unnecessary integer set,
and use close_range to deal with the actual closing of files. not only
is this clearer, it also makes sandbox setup on linux fast by 1ms each

implementing a build hook is pretty much impossible without either being
a nix, or blindly forwarding the important bits of all build requests to
some kind of nix. we've found no uses of build-hook in the wild, and the
build-hook protocol (apart from being entirely undocumented) is not able
to convey any kind of versioning information between hook and daemon. if
we want to upgrade this infrastructure (which we do), this must not stay

this is a bit of a hack, but it's apparently the cleanest way of doing
this in the absence of any kind of priority/provenance information for
values of some given setting. we'll need this to deprecate build-hook.

sure, linux has been providing argv[0] by default for a while now. other
OSes may not be as forthcoming though, and relying on the OS to create a
world in which we can just make assumptions we could test for instead is
unnecessarily lazy. we *could* default argv0, but that's a little silly.
notably we abort instead of returning normally to avoid confusions where
a caller interprets our exit status like a Worker build results bitmask.
