0631b870b0 fix(tvix/store): Improve error message for InvalidNodeName
Rather than debug-formatting a Vec<u8>, which gives just a sequence of
numbers (not very helpful!) use String::from_utf8_lossy to give a much
more human-readable error message

3d8aafb1c7 feat(tvix/store): enable name customization in the store
Sometimes, Nix lets someone customize the `name` in the store for a
path, this is the case for `builtins.path` which takes a `name`
argument, we leave it to the caller to choose the name, which can be the
basename by default of the path.

4c3ba46ba3 refactor(tvix/store): import_pathimport_path_as_nar_ca
Add multiple additional helpers such as:

- `path_to_name`: derive the basename of a given path
- `derive_nar_ca_path_info`: derive the `PathInfo` for a content
  addressed NAR

which isolates further the tree walking feature and the ingestion feature.

Additionally, we don't `expect` anymore and propagate properly ingestion errors up.

By default, this will try to push traces to a OTLP collector running at
https://localhost:4317.

You can make one available by running:

```
docker run -d --name jaeger \
  -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
  -e COLLECTOR_OTLP_ENABLED=true \
  -p 6831:6831/udp \

  -p 14269:14269 \
  -p 9411:9411 --rm \
  jaegertracing/all-in-one:1.42
```

Started like that, jaeger brings a web interface at
http://localhost:16686/search

As documented in
https://docs.rs/opentelemetry-otlp/latest/opentelemetry_otlp/, you can
point this to another location by setting `OTEL_EXPORTER_OTLP_ENDPOINT`.

a5167c508c chore(tvix): move store/fs to castore/fs
With the recent introduction of the RootNodes trait, there's nothing in
the fs module pulling in tvix-store dependencies, so it can live in
tvix-castore.

This allows other crates to make use of TvixStoreFS, without having to
pull in tvix-store.

For example, a tvix-build using a fuse mountpoint at /nix/store doesn't
need a PathInfoService to hold the root nodes that should be present,
but just a list.

tvix-store now has a pathinfoservice/fs module, which contains the
necessary glue logic to implement the RootNodes trait for a
PathInfoService.

To satisfy Rust orphan rules for trait implementations, we had to add a
small wrapper struct. It's mostly hidden away by the make_fs helper
function returning a TvixStoreFs.

It can't be entirely private, as its still leaking into the concrete
type of TvixStoreFS.

tvix-store still has `fuse` and `virtiofs` features, but they now simply
enable these features in the `tvix-castore` crate they depend on.

The tests for the fuse functionality stay in tvix-store for now, as
they populate the root nodes through a PathInfoService.

Once above mentioned "list of root nodes" implementation exists, we
might want to shuffle this around one more time.

Fixes b/341.

6815572274 refactor(tvix/store/fs): Decouple TvixStoreFs from Nix concepts
To support tvix builds, we need to be able to use the `TvixStoreFs` to
materialize the sandbox's /nix/store filesystem with just the list of
inputs needed for the build. Currently we'd need to seed an in-memory
`PathInfoService`, which includes more functionality than what is
required for `TvixStoreFs`. Additionally, the `PathInfoService` is
specific to Nix. By decoupling `TvixStoreFs` and `PathInfoService`,
we allow for usage of `TvixStoreFs` with `tvix-castore` without needing
a `PathInfoService`.

This introduces a new `RootNodes` trait which provides a way for the
filesystem to look up CA nodes via their basename in the root directory
of the filesystem. We then implement `RootNodes` for any
`PathInfoService`. Additionally, the filesystem root inode tracker now
stores basenames rather than `StorePath`s since `StorePath`s are
specific to Nix.

As a followup we can rename `TvixStoreFs` to `TvixCaStoreFs` and move
it to the `castore` crate (or its own crate).

9748543f1c chore(tvix): drop sled compression support
It's been a while since the last sled release, and that one binds to a
pretty old version of zstd, requiring workarounds like cl/10090.

Upstream sled main branch currently has zstd halfway patched out (it's
a no-op, but the feature flag and options are still there), and it's in
that state for a year.

Rather than maintaining our own fork of sled, let's just stop using the
compression feature in sled, dropping the version pin to zstd that way,
removing the need for cl/10090.

This doesn't mean we won't reintroduce per-blob compression - but we
probably just won't let sled take care of the compression, but do it
ourselves - which is necessary for more chunked blob storage anyways.

Even though we do drop the feature flag, we still need to explicitly use
use_compression(false).

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.

this linear "reading through a NAR" case, we don't need it to be clone

of people currently using this is still small, so rename the go.mod now,

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

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)

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.
