4297e33d94 feat(tvix/store/pathinfosvc): add signature verification
Introduce an Option<Vec<narinfo::PubKey>>, configurable with a
`set_public_keys` method.

If set, this configures NixHTTPPathInfoService to validate signatures.

7e8719be91 feat(tvix/store/pathinfosvc/nix_http): check Nar{Size,Hash} matches
Ensure the initially communicated NarHash/NarSize from the NarInfo
matches what we read, and don't return a PathInfo message if there's
a mismatch.

Also move the buffering layer around a bit.

fce9c0e99e fix(tvix/store/fs): don't panic on PathInfoService error
An error in the PathInfoService request can appear in case the
underlying request returns an error.

We shouldn't panic and bork the fuse mount, but instead return an IO
error.

6b685ec4a5 feat(tvix/store): add as_narinfo() for PathInfo
This allows seeing a PathInfo as a nix_compat::narinfo::NarInfo<'_>.

It doesn't allocate any new data, but the NarInfo<'_> view allows us to
access things like signature verification, or rendering out
(alternations of this) as strings.

eb84898c17 feat(nix-compat/narinfo): drop .drv from Narinfo.deriver field
We always know this needs to end with a .drv, and fail parsing if it
doesn't, so there's no need to hang onto these 4 bytes.

This will make it much easier to synthesize a NarInfo<'_> later on from
a PathInfo proto, because we don't have to make this ".drv" appear out
of thin air.

be48ba75ab feat(tvix/store/pathinfoservice): implement NixHTTPPathInfoService
NixHTTPPathInfoService acts as a bridge in between the Nix HTTP Binary
cache protocol provided by Nix binary caches such as cache.nixos.org,
and the Tvix Store Model.
It implements the [PathInfoService] trait in an interesting way: Every
[PathInfoService::get] fetches the .narinfo and referred NAR file,
inserting components into a [BlobService] and [DirectoryService], then
returning a [PathInfo] struct with the root.
Due to this being quite a costly operation, clients are expected to
layer this service with store composition, so they're only ingested
once.
The client is expected to be (indirectly) using the same [BlobService]
and [DirectoryService], so able to fetch referred Directories and Blobs.
[PathInfoService::put] and [PathInfoService::nar] are not implemented
and return an error if called.

This behaves very similar to the nar-bridge-pathinfo code in nar-bridge,
except it's now in Rust.

a11abc02e2 feat(nix-compat/nar/reader): provide passthrough buffered I/O
Allow taking advantage of the buffer of the underlying reader to avoid
unnecessary copies of file data.

We can't easily implement the methods of BufRead directly, since we
have some extra I/O to perform in the final consume() invocation.

That could be resolved at the cost of additional bookkeeping, but this
will suffice for now.

eda5d4da37 feat(tvix/store): From<&nix_compat::...::NarInfo<'_>> for PathInfo
This allows converting from the NarInfo falling out of the NarInfo
parser (which is a bit annoying to handle due to lifetimes) to the
PathInfo proto struct.

The narinfo field, containing most of the data from the original
NARInfo file, as well as the references (bytes) are populated.
The node field is not populated, because it requires ingesting the NAR
itself to describe the root node.

hang when shutting down as only one thread gets ENODEV and all the others

f8746fcab0 feat(tvix/store): Support listening on UNIX domain sockets
This adds support for listening on UNIX domain sockets via the
tokio-listener crate. The crate will automatically determine whether to
start a TCP or UNIX domain socket server based on the listen address.

Unfortunately, it's not compatible with tonic right out of the box so I
added some wrapper types to implement the necessary traits to make
things work. We should investigate upstreaming a `tonic` option to the
tokio-listener crate which implements the relevant `tonic` traits.

Example:
```
$ tvix-store daemon -l /run/tvix-store.sock
INFO tvix_store: tvix-store listening on /run/tvix-store.sock

$ tvix-store mount -l /mnt/tvix --blob-service-addr grpc+unix:///run/tvix-store.sock --directory-service-addr grpc+unix:///run/tvix-store.sock --path-info-service-addr grpc+unix:///run/tvix-store.sock

$ ls /mnt/tvix
```

32f41458c0 refactor(tvix): move castore into tvix-castore crate
This splits the pure content-addressed layers from tvix-store into a
`castore` crate, and only leaves PathInfo related things, as well as the
CLI entrypoint in the tvix-store crate.

Notable changes:
 - `fixtures` and `utils` had to be moved out of the `test` cfg, so they
   can be imported from tvix-store.
 - Some ad-hoc fixtures in the test were moved to proper fixtures in the
   same step.
 - The protos are now created by a (more static) recipe in the protos/
   directory.

The (now two) golang targets are commented out, as it's not possible to
update them properly in the same CL. This will be done by a followup CL
once this is merged (and whitby deployed)

d8ef0cfb4a docs(tvix/castore): rename traverse_to -> descend_to
With the move of this code out into castore it has become apparent this
is a general descent inside the castore. Concerns like making sure the
whole Directory closure has been fetched/is fetched initially is nothing
this layer needs to worry about. We can handle this during substitution
of a new PathInfo, once there's store composition.

Closes b/270.

`fuse` module holds the code to spawn a FUSE daemon backed by multiple
threads.

6b7c936bc5 refactor(tvix/store/fuse): Switch from fuser to fuse-backend-rs
This switches the FUSE implementation from fuser to fuse-backend-rs.
fuse-backend-rs is designed to work with both FUSE and virtiofs.
Virtiofs support will make it possible to plug the tvix-store into a
microvm and have `/nix/store` access without having to setup FUSE inside
the guest.

Additionally fuse-backend-rs has nice support for running multiple FUSE
threads and has some async support.

The goal of this commit is to mechanically switch over to
fuse-backend-rs with minimal changes. I did have to add some locks here
and there because fuse-backend-rs uses `&self` on all methods whereas
fuser uses `&mut self`. `&self` is required for concurrent access to the
FUSE server, so this makes sense.

We can consider switching to concurrent maps and use some other
techniques to reduce lock contention and critical section size.

da6cbb4a45 refactor(tvix/store/blobsvc): make BlobStore async
We previously kept the trait of a BlobService sync.

This however had some annoying consequences:

 - It became more and more complicated to track when we're in a context
   with an async runtime in the context or not, producing bugs like
   https://b.tvl.fyi/issues/304
 - The sync trait shielded away async clients from async worloads,
   requiring manual block_on code inside the gRPC client code, and
   spawn_blocking calls in consumers of the trait, even if they were
   async (like the gRPC server)
 - We had to write our own custom glue code (SyncReadIntoAsyncRead)
   to convert a sync io::Read into a tokio::io::AsyncRead, which already
   existed in tokio internally, but upstream ia hesitant to expose.

This now makes the BlobService trait async (via the async_trait macro,
like we already do in various gRPC parts), and replaces the sync readers
and writers with their async counterparts.

Tests interacting with a BlobService now need to have an async runtime
available, the easiest way for this is to mark the test functions
with the tokio::test macro, allowing us to directly .await in the test
function.

In places where we don't have an async runtime available from context
(like tvix-cli), we can pass one down explicitly.

Now that we don't provide a sync interface anymore, the (sync) FUSE
library now holds a pointer to a tokio runtime handle, and needs to at
least have 2 threads available when talking to a blob service (which is
why some of the tests now use the multi_thread flavor).

The FUSE tests got a bit more verbose, as we couldn't use the
setup_and_mount function accepting a callback anymore. We can hopefully
move some of the test fixture setup to rstest in the future to make this
less repetitive.

3c340b28bd refactor(tvix/{cli,store}): move TvixStoreIO to tvix-cli crate
This trait is eval-specific, there's no point in dealing with these
things in tvix-store.

This implements the EvalIO interface for a Tvix store.
The proper place for this glue code (for now) is tvix-cli, which knows
about both tvix-store and tvix-eval.

There's one annoyance with this move: The `tvix-store import` subcommand
previously also used the TvixStoreIO implementation (because it
conveniently did what we wanted).
Some of this code had to be duplicated, mostly logic to calculate the
NAR-based output path and create the PathInfo object.

Some, but potentially more of this can be extracted into helper

0193f07642 refactor(tvix/nix-compat/nixhash): validate digest lengths
There was a NixHash::new() before, which didn't perform any validation
of the digest length. We had some length validation when parsing nix
hashes or SRI hashes, but some places didn't perform validation and/or
constructed the struct directly.

Replace NixHash::new() with a
`impl TryFrom<(HashAlgo, Vec<u8>)> for NixHash`,  which does do this
validation, and update constructing code to use that, rather than
populating structs directly. In some rare cases where we're sure the
digest length is correct we still populate the struct manually.

Fixes b/291.

72e82ffcb1 refactor(tvix/store): use bytes for node names and symlink targets
Some paths might use names that are not valid UTF-8. We should be able
to represent them.

We don't actually need to touch the PathInfo structures, as they need to
represent StorePaths, which come with their own harder restrictions,
which can't encode non-UTF8 data.

While this doesn't change any of the wire format of the gRPC messages,
it does however change the interface of tvix_eval::EvalIO - its
read_dir() method does now return a list of Vec<u8>, rather than
SmolStr. Maybe this should be OsString instead?

This "reverts" commit 9f600de226 (the
initial revert of f5e291cf83).

Now with BlobService returning a BlobReader that implements io::Seek, we
can actually just call blob_reader.seek(io::SeekFrom::Start(offset as
u64)).

This means, we currently will fail to seek backwards inside a file.

42dc18353d feat(tvix/nix-compat): have StorePath accept bytes
The primary constructor for this is now from_bytes, from_string is
simply calling .as_bytes() on the string, passing it along.

The InvalidName error now contains a Vec<u8>, to encode the invalid name
(which might not be a string anymore).

from_absolute_path now accepts a &[u8] (even though we might want to
make this a OSString of some sort).

StorePath::validate_name has been degraded to a pub(crate) function.
It's still used in src/derivation, even though it probably shouldn't at
all - that cleanup is left for cl/8412 though.

b25d98a84e feat(tvix/store/fuse): initial implementation
This is a first implementation of a FUSE filesystem, mounting tvix-store
to a given location.

This is mostly meant as one additional lens into a store, and could be
used for builds. It's not meant to be used as a general-purpose thing.

It still has some rough edges:

 - It doesn't implement open/close, so it doesn't use file handles.
   Which means, we need to open blobs for partial reads over and over
   again.
 - It doesn't implement seek, as BlobReader doesn't implement seek yet.
 - It doesn't track "lifetimes" of inodes by listening on forget,
   meaning it might hold more data in memory than necessary.
 - As we don't have store composition (and a caching layer) yet,
   operations might be slow.

There's only one way to calculate NAR files, by walking through them.

Things like caching such replies should be done closer to where we use
these, composing NARCalculationService doesn't actually give us much.

Instead, expose two functions, `nar::calculate_size_and_sha256` and
`nar::writer_nar`, the latter writing NAR to a writer, the former using
write_nar to only keeping the NAR size and digest.

92b6d15da3 fix(tvix/store/bin): use spawn_blocking to call import_path
This operation is blocking, so it should be run inside a blocking tokio
task. Tokio panics if it detects a blocking operation inside a non-
blocking task, so cl/8619 would cause it to panic (as the GRPC clients
use spawn_blocking under the hood).

As spawn_blocking moves, and we can't clone `TvixStoreIO` (see cl/8614),
we create a new instance of TvixStoreIO inside each loop iteration.

3a4e29c261 refactor(tvix/store): rename import::{import_path -> ingest_path}
This distinguishes it better from the EvalIO::import_path method.
Also update the docstring to explain what it does (and what it doesn't).

e815b680c0 refactor(tvix/store/pathinfosvc): drop ByWhat, use digest directly
We currently only support querying by the output hash digest.
This makes the interface a bit simpler.

616fa4476f refactor(tvix/store): remove ChunkService
Whether chunking is involved or not, is an implementation detail of each
Blobstore. Consumers of a whole blob shouldn't need to worry about that.
It currently is not visible in the gRPC interface either. It
shouldn't bleed into everything.

Let the BlobService trait provide `open_read` and `open_write` methods,
which return handles providing io::Read or io::Write, and leave the
details up to the implementation.

This means, our custom BlobReader module can go away, and all the
chunking bits in there, too.

In the future, we might still want to add more chunking-aware syncing,
but as a syncing strategy some stores can expose, not as a fundamental
protocol component.

This currently needs "SyncReadIntoAsyncRead", taken and vendored in from
https://github.com/tokio-rs/tokio/pull/5669.
It provides a AsyncRead for a sync Read, which is necessary to connect
our (sync) BlobReader interface to a GRPC server implementation.

As an alternative, we could also make the BlobReader itself async, and
let consumers of the trait (EvalIO) deal with the async-ness, but this
is less of a change for now.

In terms of vendoring, I initially tried to move our tokio crate to
these commits, but ended up in version incompatibilities, so let's
vendor it in for now.
