When removing the f1 repl characterization test suit, these files were
kept on accident, despite them being dead code now

This reverts commit 0d6b372c19.
Reason for revert: In the time between this getting +2 and it being merged, all repl tests and its syntax have been migrated to f2, making these changes null and to dead code

Gosh. Why was there never a README in here explaining what it does
without requiring people to read C++? There was a half-assed grammar in
a comment, but it was very half-assed, so let's replace it with a
better-written one.
I'm documenting this so that neither I nor anyone else have to read C++
while rewriting the parser in Python.

When extracting a global pyproject.toml from the f2 one, some f2
specific things slipped through and ended up in the global one.
This commit moves those parts back where they belong

So apparently we can still use the repl if the input file fails, as long
as we have the debugger enabled.
This Commit removes the "only one output block for should_fails"
requirement to allow this behavior

what the actual fuck. swallowing all errors *except* EXDEV is not okay.
renames do not do this, so moves should not do it either. luckily we do
not use moveFile anywhere except the store path registration code. this
may or may not have caused problems in the past. probably nobody knows.

If e.g. i686-linux is not in the list of systems and thus no attribute in `nixpkgsFor`
exists (e.g. on hydra.afnix.fr), don't try to instantiate it.

The reference to the flake is used in a single place only to get the
`doc` output of Lix. Remove it so that we can also instantiate the tests
in a legacy Hydra jobset (happening further down the chain).

Noticed on my quest to make Lix buildable against multiple nixpkgs' to
provide pre-warmed caches for the flake on AFNix's Hydra.
`pkgs.systemd` has a new patch policy[1] that only allows patches for
hotfixes and fundamental incompatibilities. As such, the patch that
allows nspawn workloads to start without a `/usr/bin` was removed with the
recommendation to create that stub yourself.

The option has been broken since Nix 2.4. The flag was accepted, but not
used. This change plumbs it through to computeFSClosure.

this logs unpackTarfile calls as an `actUnknown` activity, which
unfortunately doesn't report any progress for now. for the reasoning
behind this choice, see the previous iterations of this CL (cl/5590)
as well as the attached comments (the crux of the conversion is in DMs,
unfortunately). in short:
- i could't make a new ActivityType because that would be a breaking
change to the daemon protocol, including with previous lix versions
- i can't use actFileTransfer because that would show up as a download,
which would be confusing for both users and tools
- i can't use actCopyPath /or/ actCopyPaths because that would break
NAR/substitution accounting when doing remote builds
also, ArchiveDecompressionSource, which is apparently used for
decompressing logs etc, does its own custom decompression without using
unpackTarfile, so it is not affected by this. from what i can tell,
unpackTarfile is only used for:
- fetchtarball fetcher
- git fetcher
- channel unpacking
- nix-prefetch-url

By default, when one uses `in` assertions, upon failure newlines in any
of the two strings is escaped, and everything is printed in a single
line.
This commit allows one to pass `-vv` to print out the left and righthand
side unescaped, with each line of the output being its own line,
improving readability a lot when dealing with multiline outputs.

It's software archaeology time.
- In 2019 (Nix 2.4), Eelco added `checkOverlays`, which strictly checked
that the overlay must be a function of two arguments, one called `final`
and the other `prev`. (dc3f52a144,
gh#3573)
- In 2024, NofairKing opened an issue about checking the exact name
being a silly idea (gh#10516). Instead of trying to make the check more
sensible, the first fix attempt simply expanded the check to allow
`previous` instead of `prev` (the author's preferred name for the
attribute, supposedly; gh#10553). After some discussion, instead a PR
got merged which simply removed the `prev` check altogether, while
leaving the `final` argument check intact for some reason
(ad65a50a94a97bf1f1a1902f43542d28a2e8206b, gh#10572).
- In 2025, over at Lix and oblivious to the latest change over at
CppNix, I came across this stupid check while trying to improve the
abstractions of the AST in Nixexpr. I spent (wasted, retrospect)
considerable amounts of time removing the exact name checks while also
improving the check overall (making it check for more than two
arguments, and also generally improved error message).
(0928d4d87a,
Id4244171123dd8a228be71ce9f04d8e9f647c111)
- Fast forward to 2026, where I run into this becursed piece of code
once again, and once again during some Lixexpr cleanups. Now that I have
seen how carlessly the issue was handled at CppNix, I can't be arsed to
give a flying fuck anymore. Out the code goes. Bye.
With this commit, all casts on `Expr` subclasses outside of libexpr
itself have been removed. No more violation of abstraction boundaries.
Good riddance.

pour the foundations for rpc, and let them set. this is very much
unstable and must be opted into with explicit store uris (e.g. by
setting `NIX_REMOTE=daemon?protocol=any`). the daemon sockets are
not enabled by default and must be enabled with the `rpc-sockets`
experimental feature. we will not advertise this just yet because
in the current state it one has to be *very* dedicated to the rpc
cause to deploy this, but once we have some more bits migrated we
may want to add release notes and officially as for beta testing.

this adds the protocol registry. we also extend the systemd unit setup
to allow adding new protocols without much fussing, and we move deamon
instances into protocol-dependent scopes. this will make monitoring or
resource limiting of individual protocol daemon instances much easier.

string data shares a buffer with the binary string length field. size
calculations for string read buffers always include the length field;
sufficiently large length fields can cause these calculations to wrap.
a malicious nar could use this for OOB writes in the daemon (as root).
since we use strings only as tags for archive members and for symlinks
with their OS-dependent length limits we can simply limit string size.
1 MiB should be sufficient for all symlinks, and tags are always tiny.

This isn't really relevant for a setting of 10k, but now that we want to
set it to 0 for Flakes it makes a difference as to whether or not one
top-level function call is allowed or not. (It shouldn't be)

Caught by edef's harness. I rewrote the structured build log tests in
f2 and added a test for this one.
Before: it failed the build altogether:
```
building '/tmp/jade/pytest-of-jade/pytest-77/test_invalid_fields_files0_0/nix/store/skhjs5zs082nqiakj69qz32gyywz0v1a-unusual-loggi
ng.drv'...
error: unsupported JSON type 7
```
Now the output is as expected:
```
warning: Unable to handle a JSON message from the derivation builder: error: unsupported log field type number
@nix {"action": "start", "fields": [1.5], "id": 2, "type": 1, "level": 1, "text": "abc"}

Basically having the error point to the operand instead of the operator
kind of makes sense, but it would require error spans to *truly* make
sense, and in the meantime maintaining the logic is more hassle than it
is worth.

We choose to throw an error in the invalid-input space where we *can*
produce a valid (but wrong) result to allow ourselves to, mirroring
CppNix, change the semantics to not corrupt it at all in the future,
while having a middle state where it is an error.
