Since a recent nixpkgs bump bringing a version of cargo with
https://github.com/rust-lang/cargo/pull/12914,
crate2nix creates a crate-hashes.json with all crate hashes from
Cargo.lock (and downloads a lot of stuff while producing it).
https://github.com/nix-community/crate2nix/pull/341 prevents this from
happening, but our hardcoded crate2nix pin prevented us from getting the
fix included in 0.14.0, which did land in nixpkgs.
Replace the pin with a simply override, carrying our only leftover patch
on top of it, and link to that PR.

We however now need to convert from a std::path::Path to our

EvalIO might contain this. Dealing .. to hop into another store path, if

We actually want to delay fetching until we actually need the file. A
simple evaluation asking for `.outPath` or `.drvPath` should work even
in a pure offline environment.
Before this CL, the fetching logic was quite distributed between
tvix_store_io, and builtins/fetchers.rs.
Rather than having various functions and conversions between structs,
describe a Fetch as an enum type, with the fields describing the fetch.
Define a store_path() function on top of `Fetch` which can be used to
ask for the calculated store path (if the digest has been provided
upfront).
Have a `Fetcher` struct, and give it a `fetch_and_persist` function,
taking a `Fetch` as well as a desired name, and have it deal with all
the logic of persisting the PathInfos. It also returns a StorePathRef,
similar to the `.store_path()` method on a `Fetch` struct.
In a followup CL, we can extend KnownPaths to track fetches AND
derivations, and then use `Fetcher` when we need to do IO into that
store path.

I had a `NixString`, wanted to return it as a `String`, so I was naively
calling `s.into()`.
That unfortunately gave me the `Display` implementation of `NixString`,
which quotes strings, causing an annoying error further up the stack.
NixStrings are bytes, we can keep the impl From<NixString> for BString,
but having a `.into()` suddenly do quoting is more than unexpected.

Rather than carrying around an Future in the IngestionEntry::Regular,
simply carry the plain B3Digest.
Code reading through a non-seekable data stream has no choice but to
read and upload blobs immediately, and code seeking through something
seekable (like a filesystem) probably knows better what concurrency to
pick when ingesting, rather than the consuming side.
(Our only) one of these seekable source implementations is now doing
exactly that. We produce a stream of futures, and then use
[StreamExt::buffered] to process more than one, concurrently.
We still keep the same order, to avoid shuffling things and violating
the stream order.
This also cleans up walk_path_for_ingestion in castore/import, as well
as ingest_dir_entries in glue/tvix_store_io.

Previously the store ingestion code was coupled to `walkdir::DirEntry`s
produced by the `walkdir` crate which made it impossible to reuse
ingesting from other sources like tarballs or NARs.
This introduces a `IngestionEntry` which carries enough information for
store ingestion and a future for computing the Blake3 digest of files.
This allows the producer to perform file uploads in a way that makes
sense for the source, ie. the filesystem upload could concurrently
upload multiple files at the same time, while the NAR ingestor will need
to ingest the entire blob before yielding the next blob in the stream.
In the future we can buffer small blobs and upload them concurrently,
but the full blob still needs to be read from the NAR before advancing.

Use a proper graph library to ensure all nodes are reachable from the
root.
We had a bit of that handrolled during add(), as well as later, which
had an annoying bug:
Redundant nodes were omitted during insert, but when returning the list
during finalize, we did not properly account they need to be introduced
before their parents are sent.
We now simply populate a petgraph DiGraph during insert (skipping
inserting nodes we already saw), and use petgraph's DfsPostOrder to
traverse the graph during finalize.
If the number of returned indices equals the total number of nodes in
the graph, all nodes are reachable from the root, we can consume the
graph and return the nodes as a vec, in the same order as the traversal
(and insertion).
Providing a regression test for the initial bug is challenging, as the
current code uses a bunch of HashSets. I manually tested ingesting a
full NixOS closure using this mechanism (via gRPC, which exposes this
problem, as it validates twice), and it now works.

This tells josh to include the patch from
third_party/overlays/patches/cbtemulator-uds.patch at
nixpkgs/cbtemulator-uds.patch.
We then use the `additionalOverlays` feature introduced earlier, and
pass it an overlay adding the patch to `cbtemulator`.
This only gets applied if tvix/shell.nix is not called with a pkgs
argument, which is the case in the tvix view.

This allows copying individual store paths from the local /nix/store
into tvix-store.
As we don't support getting this information from Nix yet, we currently
expect metadata to be provided externally:
Nix' `exportReferencesGraph` feature contains pretty much all data we
need for this. Expect a list of this information at a well-known key
(`closure`, similar to nixpkgs' `pkgs/build-support/binary-cache/
default.nix`).
We currently simply upload all store paths sequentially, without any
parallelism or awareness in how the reference graph looks like.
As long as the connected stores don't enforce this, this is fine, at
least for now.

`toJSON` transform a Nix structure into a JSON string.
For each context in that Nix structure, the JSON string must possess it.
Thus, it is necessary to take the union of all contexts and attach it to
the final structure.
Unfortunately, the return type of `into_json` is a serde's JSON object,
not a string. Therefore, it is not possible to reuse `NixString`
machinery.
Context tests are reinforced as Nix does not test those behaviors.

We were wrongly using `'de` as a lifetime for both `Deserializer` and
`StorePathRef`.
This prevented Deserializing into a struct containing `StorePathRef`.
See https://serde.rs/lifetimes.html#the-deserializede-lifetime, the last
part of the paragraph:
The 'de lifetime should not appear in the type to which the Deserialize
impl applies.
- // Do not do this. Sooner or later you will be sad.
- impl<'de> Deserialize<'de> for Q<'de> {
+ // Do this instead.
+ impl<'de: 'a, 'a> Deserialize<'de> for Q<'a> {
This fixes it, and adds a test, deserializing into a `Container` struct.
It also fixes the existing test cases, deserialize_ref was actually
deserialize_owned, and deserialize_owned didn't exist yet - but they
alone are not enough to provoke the lifetime issues.

Note that a dependency on `${d.drvPath}` generates an input source
dependency too.
This is a complete implementation of the context string system in Nix on
the "input population" side.
The test coverage of this change is taken care in cl/11264.

This drops pretty much all of castore/utils.rs.
There were only two things left in there, both a bit messy and only used
for tests:
Some `gen_*_service()` helper functions. These can be expressed by
`from_addr("memory://")`.
The other thing was some plumbing code to test the gRPC layer, by
exposing a in-memory implementation via gRPC, and then connecting to
that channel via a gRPC client again.
Previous CLs moved the connection setup code to
{directory,blob}service::tests::utils, close to where we exercise them,
the new rstest-based tests.
The tests interacting directly on the gRPC types are removed, all
scenarios that were in there show now be covered through the rstest ones
on the trait level.

This can be used to validate a Directory closure (connected DAG of
Directories), and their insertion order.
Directories need to be inserted (via `add`), in an order from the leaves
to the root. During insertion, we validate as much as we can at that
time:
- individual validation of Directory messages
- validation of insertion order (no upload of not-yet-known Directories)
- validation of size fields of referred Directories
Internally it keeps all received Directories (and their sizes) in a HashMap,
keyed by digest.
Once all Directories have been inserted, a drain() function can be
called to get a (deduplicated and) validated list of directories, in
from-leaves-to-root order (to be stored somewhere).
While assembling that list, a check for graph connectivity is performed
too, to ensure there's no separate components being sent (and only one
root).
It adds a test suite for these cases, which is much nicer to test than
where we previously had these checks (only in the gRPC server wrapper).
Followup CLs will move the existing putters to use this.

The latter uploads the path as a closure (so including its references,

We use nar-bridge, and the HTTP interface it provides to do this.
As `nix copy` can't be used inside a Nix build, we use
