dbf87f3057 chore(tvix): bump tonic to 0.11.0
This bumps tonic and surrounding crates to 0.11.x.

We added support for tonic 0.11.x into tokio-listener
(https://github.com/vi/tokio-listener/pull/4), so that's bumped as well.

1c16dee207 feat(tvix/store): use reqwests' rustls-native-roots feature
This makes reqwest honor `SSL_CERT_FILE` - previously it was using the
chain bundled in webpki-roots.

`object_store` pulls in `reqwest` with this feature, and the cargo
solver will enable that feature globally as soon as we pull it in, as it
assumes features are additive.

This requires setting `SSL_CERT_FILE` when running tests, otherwise
they'll fail with the unhelpful "NotFound" error.

This was quite some fun to debug, why adding `object_store` to
tvix-castore suddenly made tvix-store tests fail!

3307791855 feat(tvix/store): add opentelemetry
This is behind the otlp feature flag (currently enabled by default).

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`.

8d86d2f409 refactor(tvix/castore): add RootNode impl for BTreeMap, mv fs tests
cl/10378 did already move store/fs to castore/fs, but we kept the tests
in tvix-store, as they were populating a PathInfoService to make nodes
appear in the mount root.

Update these tests to now just insert root nodes into a BTreeMap, and
ensure we can use that as a RootNodes too.

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.

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.

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

Notable changes:

   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.

f499d2e031 feat(tvix/store): fix ctrl-c handling on mount command
This enables the tokio `signal` feature, and registers a ctrl_c signal
handler, which will use the unmount handle to unmount in case a ctrl-c
signal is received.

This avoids having disconnected mountpoints when Ctrl-C'ing a
`tvix-store mount` invocation.

In case the filesystem is unmounted externally (via `umount /path/to/
mountpoint`), the future is waiting for the signal is never resolved and
the task is stopped.

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
functions in a shared crate, and then be used from both TvixStoreIO in
tvix-cli as well as the tvix-store CLI entrypoint.

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.

367a5e9922 feat(tvix/store/directorysvc): add gRPC client
This provides a GRPCDirectoryService struct implementing
DirectoryService, allowing a client to Directory objects from a (remote)
tvix-store.

Remote in this case is anything outside the current process, be it
another process, or an endpoint on the network.

To keep the sync interface in the `DirectoryService` trait, a handle to
some tokio runtime needs to be passed into the constructor, and the two
methods use `self.tokio_handle.spawn` to start an async function, and
`self.tokio_handle.block_on` to wait for its completion.

The client handle, called `grpc_client` itself is easy to clone, and
treats concurrent requests internally. This means, even though we keep
the `DirectoryService` trait sync, there's nothing preventing it from
being used concurrently, let's say from multiple threads.

There's still two limitations for now:

1) The trait doesn't make use of the `recursive` request, which
   currently leads to a N+1 query problem. This can be fixed
   by `GRPCDirectoryService` having a reference to another
   `DirectoryService` acting as the local side.
   I want to wait for general store composition code to pop up before
   manually coding this here.

2) It's currently only possible to put() leaf directory nodes, as the
   request normally requires uploading a whole closure. We might want
   to add another batch function to upload a whole closure, and/or do
   this batching in certain cases. This still needs some more thinking.

36bed4ce57 chore(tvix/store): drop separate bin package
Apparently, having multiple packages with the same path is a bad thing:

```
The bin target `tvix-store` in package `tvix-store-bin v0.1.0 (/home/flokli/tvl/tvix/store)` has the same output filename as the lib target `tvix_store` in package `tvix-store-bin v0.1.0 (/home/flokli/tvl/tvix/store)`.
Colliding filename is: /home/flokli/tvl/tvix/target/doc/tvix_store/index.html
The output filenames should be unique.
This is a known bug where multiple crates with the same name use
the same path; see <https://github.com/rust-lang/cargo/issues/6313>.

This was the last piece of code using BlobWriter.

We can also use `read_all_and_chunk`, it's just requires a bit more
plumbing:

 - The data coming from the client (stream) needs to be mapped (we
   extract the .data field).
 - The stream needs to be turned into an (async) reader
 - The reader needs to be made sync, and that code using the sync reader
   needs to be in a `task::spawn_blocking`.

Look at the data that's written to us, and upload all chunks but the
rest in parallel, using rayon. This required moving `upload_chunk`
outside the struct, and accepting a ChunkService to use for upload
(which it was previously getting from `self.chunk_service`).

This doesn't speed up things too much for now, because things are still
mostly linear.

a40d2dcdcd feat(tvix/store): bump fastcdc, use v2020 version
This switches away from the less canonical "ronomon" version to the
implementation as described in the
[paper](https://ieeexplore.ieee.org/document/9055082) by Wen Xia, et
al., in 2020.

That version uses 64-bit hash values and tends to be faster than both
the ronomon and v2016 versions, and produces the same chunking as the
2016 version.

As per https://docs.rs/fastcdc/latest/fastcdc/#implementations-1, it's
the recommended choice.

The crate also gained support for streaming version of chunkers:
https://docs.rs/fastcdc/latest/fastcdc/#large-data, which might be
useful.
