41a0b08e64 meson: Don't use target_machine
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.

5137cea990 README: clarify license to match documentation
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.

b9ed79c99a libutil: deal with Linux systems that do not implement close_range
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.

b15d5cc6ee nix: remove explosions if you have a window size less than four
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.

0c76195351 build: remove expect as a dependency
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.

292567e0b0 fix: check if it is a Real terminal, not just if it is a terminal
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.

3775b6ac88 package: remove unused autotools code, empty file
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.

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

35a2f28a46 libstore: deprecate the build-hook setting
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

baa4fda340 main: require argv[0]
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.

4ed8461cac sqlite: add a Use::fromStrNullable
There were several usages of the raw sqlite primitives along with C
style casts, seemingly because nobody thought to use an optional for
getting a string or NULL.

a318c96851 util: implement charptr_cast
I don't like having so many reinterpret_cast statements that have to
actually be looked at to determine if they are UB. A huge number of the
reinterpret_cast instances in Lix are actually casting to some pointer
of some character type, which is always valid no matter the source type.

However, it is also worth looking at if it is not casting both *from* a
character type and also *to* a character type, since IMO splatting a
struct into a character array should be a very deliberate action instead
of just being about dealing with bad APIs.

So let's write a template that encapsulates this invariant so we can
not worry about the trivially safe reinterpret_cast invocations.

This:
- Converts a bunch of C style casts into C++ casts.
- Removes some very silly pointer subtraction code (which is no more or
  less busted on i686 than it began)
- Fixes some "technically UB" that never had to be UB in the first
  place.
- Makes finally follow the noexcept status of the inner function. Maybe
  in the future we should ban the function from not being noexcept, but
  that is not today.
- Makes various locally-used exceptions inherit from std::exception.

This still has utterly unacceptably bad output format design that I

Future work would obviously be to fix that and integrate the actual

8a86f38bca Fix is_maintenance_branch heuristic
This was broken because Nix language's version comparison does not know
how to deal with versions like -rc1 and considers them newer, which is
in this case not desirable.

That in turn led to not tagging 2.90.0 docker images as "latest" since
the heuristic was wrong.

This commit also adds some more cross-checking and failsafes in case the
person running releng does not have a local main branch that is up to
date.

ec7552ff74 libexpr/parser: Test experimental features
Currently, the parser relies on the global experimental feature flags.
In order to properly test conditional language features, we instead need
to pass it around in the parser::State.

This means that the parser cannot cache the result of isEnabled anymore,
which wouldn't necessarily hurt performance if the function didn't
perform a linear search on the list of enabled features on every single
call. While we could simply evaluate once at the start of parsing and
cache the result in the parser state, the more sustainable solution
would be to fix `isEnabled` such that all callers may profit from the
performance improvement.
