the test is for the map that usually wraps it though because it's the
bit we're interested in replacing, and it has custom serializer code.

the old protocols are largely untested, mostly unused, and have design
problems that make the RPC transition a lot harder, if not impossible.
in theory we could ship a transparent protocol-converting proxy that'd
isolate the daemon itself from old protocol versions, but that's a lot
of code to maintain for presumably little gain or even no gain at all.

All changes are uniform and done with the same script, so checking only
some should suffice. For that reason, any tests involving multiple files
or custom CLI flags are not included in this commit.

The current `RelativeTo` design is both more complex and more confusing
than necessary. Its four variants are now reduced to only two. They are
now also represented as different classes, to better communicate the
difference in semantics and also intent.

Previously, paths not being deleted by gcDeleteSpecific would result in
(a) hardlinks not being cleaned up, and
(b) statistics not being reported correctly.
By throwing the error later, we fix both of these problems.

By default, xfail tests will always "pass" when the test fails,
disrecsarding any restrictions put on them via their parameters.
By enabling the `xfail_strict` option, xfails won't pass anymore when
the failstate is different from what is described in their parameters.

Remote binary caches support `write-nar-listing` options where they create a `HASH.ls` file for quick indexing without having to download the nar.
This commit makes experimental `nix store ls` attempt to read these files instead of downloading the full nar.
The difference is very obvious with large packages like stellarium:
nix store ls --store "https://cache.nixos.org" /nix/store/ijpvwgs9zamqaax5dy2cd0kxgz7lr7an-stellarium-25.1 -R

including common fixtures and where to find them
This is done to make the migration from functional easier and give devs
a reference for how one writes tests

This creates a framework similar to the old lang.sh from functional.
Some notable changes:
- instead of having a .flags file, a test.toml can declare flags
- additionally the test.toml can also declare extra files and multiple
runners for the given input file.
- there won't be any old tests hanging around anymore which weren't
deleted properly in the installation
- all files for a single test are defined decleratively and there won't
be any residues
Tests can be placed within the functional2/lang folder
most migrations should be rather clean

Due to how meson works with the current justfile options, it is not
possible to pass additional arguments into the functional2 test

Due to that, it isn't possilbe to narrow down what tests to execute or

This commit adds an additional recipe, calling pytest directly ensuring
arguments are handed through

The first auto-GC request would not be registered as a waiter due to a logic
error. As a result, if that request was synchronous (as happens during
evaluation) it would be stuck forever waiting on a promise that will never be
fulfilled.
Register also the first request properly so that it is notified and unblocked
again when the GC has finished. Also add a test verifying that auto-GC
triggering during evaluation will not get stuck.

The custom subcommand test fixture used to replace the environment
with PATH prepended with the directory of the subcommand.
This caused the tests to fail on darwin with auto-allocate-uids
enabled, as the dynamic users aren't added to the user database
inside the sandbox, as opposed to linux.
Other environments were unaffected because the build user is a real user
with a database entry and HOME set.
Update the environment instead, also preserving hermetic env
created earlier by NixCommand constructor.

The experimental `nix eval` command already supports a `--raw` flag.
This commit implements the same flag for the stable nix-instantiate command.
Until now instructions and scripts that didn't want to rely on experimental
features had to use workarounds such as:
nix-instantiate --eval <something> | tr -d \"
(which also undesirably also removes double quotation marks within the string), or
nix-instantiate --eval <something> | jq -j
(which undesirably depends on another package).

`fetchGit` has been modified a long time ago to use fetchTree, however,
we don't care about `lastModified` because we are not in a flake
context, this hack introduces a `git-locked` type of input that only
cares about `narHash` being present. This is needed to avoid fetching
the remote repo each time `fetchGit` is evaluated whith the result
present in the store.

When assigning an a value to NIX_GET_COMPLETIONS that could not be
parsed as an integer lix would just crash, as the value was directly
passed to stoi, without handling the return value.
This change switches the parsing to use string2Int and throws an
exception if the return value is empty.
The behaviour of lix is slightly changed through, as the value of the
variable was previously parsed to an int and then assigned to a variable
of size_t.
This change in behaviour can only be observed in cases where the
value of NIX_GET_COMPLETIONS is chosen so when it overflows it would
be valid index of the provided arguments again.
Through this change the variable is parsed as a size_t and negative
values are rejected.

When using completion, the number of the word for which the shell
requests completion is provided in the environment variable
`NIX_GET_COMPLETIONS`. When the number smaller than 1 is or larger
than the number of arguments nix coredumps as a assert is violated.
This change removes the assert and instead throws an exception informing
the user that their autocomplete is most likely misconfigured.

This introduces a new (demanded?) feature for coercing integers in
interpolation arguments under the experimental feature
`coerce-integers`.
This feature is being introduced behind an *experimental feature flag*
due to the cautious approach we're taking. The codebase has a track
record of revealing unexpected behaviors, often in subtle ways, so we
want to give this sufficient time and exposure before making it stable.
To remove the experimental flag, we want to see **at least two releases
or six months of real-world usage -- whichever is longer** -- that
demonstrate strong confidence the feature doesn't introduce regressions
or unintended side effects. If that level of confidence is reached,
we'll proceed to stabilize it.

To print completions lix created a Finally object containing the actual function,
so the function was executed by the destructor of the class.
Unfortunately aborting autocomplete by sending a SIGINT signal
(i.E. by pressing C-c) leads to an exception, that finally cant return or eat,
when throwing its own exception.
To avoid crashing when using auto complete let the function "mainWrapped" execute
the autocomplete code directly before returning.
This avoids creating the "Finally" object and instead moves the codeblock next to
the check to return when "arg.completions" is called.

When calling completion on a nix command containing the word
"--help" nix would first return the entire help page for the
command and then the result of the completion resulting in unusable
output.
By moving the check whether to return when completions were requested
before the check whether help was requested wrappedMain returns
without wrongly printing documentation.

Each `inputFromAttrs` is roughly the same function in each class, we

specific per child class.

Due to nix-store making its paths read-only, pytest was unable to remove
the test files and hence the entire temporary directory, screaming all
over the place in stderr about that, getting worse for each test run.
By making the nix fixture first yield nix and then, after the test
finished running, changing the file permissions to include read on all
files and directories within the temp folder, pytest is able to properly
remove old test runs again
Additionally added more clear instructions for file deletion to the
pytest configuration

It was introduced back in 2013, was disabled in 2014 again for dubious

It was the only disabled test, so I removed the "infrastructure" for

Back in the days, this used to be the modus operandi, but then, still
many but less years ago, Eelco came along and changed it to passing in
the actual file. Of course, no motivation was provided, and it was only
done on half of the test runners for some reason, leaving us to wonder
what the true intentions of this code are …
Anyways, with this commit now everything standardises on passing in the
file by path instead of via stdin. Motivation:
- We need to `sed` out the path anyways for various other reasons,
including import tests and path value tests
- Given that, the presumed primary motivation for using stdin in the
first place becomes moot
- Bonus points for giving better error messages, especially in tests
that involve multiple input files
