cd820d07d7 chore(nix-compat): remove unused test-case and test-generator
This is especially nice, as it allows us getting rid of the other
versions of proc-macro2 and quote.

cf47294b9e feat(tvix/boot): boot nixos VM
This makes use of the vmCmdline and assertVMOutput to boot a NixOS VM
off of `tvix-store virtiofs` have it write a message on successful
bootup, then have it shut down again.

We check we see the message in the output.

Seeding the store with the closure it's what's currently taking most
of the time (as it's all linear still), so log a message before booting
the VM.

28e98af9bc fix(tvix/castore/blobservice/chunk_rd): only skip *first* chunk bytes
When (re)initializing a chunked reader, we were erroneously skipping the
first n bytes from all chunks, not just the first one.

Fix this, by passing in an enumerated list of chunks, and only calling
SeekFrom::Start() on the first chunk in the stream.

With this, I'm able to invoke b3sum on bin/bash successfully.

b025a30d27 refactor(tvix/castore/fs): remove From<Node> for InodeData
These were copying unnecessarily. Instead, have a
InodeData::from_node(), which *consumes* the Node entirely, returns
`InodeData` and the split-off name (which is not part of InodeData).

Callers can then use the result in various helper functions, like:

 - InodeData::as_fuse_type
 - InodeData::as_fuse_file_attr
 - InodeData::as_fuse_entry

… to prepare their replies to the kernel.

This removes not only a bunch of clones, but also a lot of copy-pasted
code.

9498ac936e fix(tvix/castore/directory): fix graph traversal
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.

d3d88431f3 feat(tvix/castore/fs): assign read[dir*]/release[dir] ops to parent span
When a directory or file is open()'ed, we already put some data into
a lookup table, and subsequent operations then use the returned handle
id.

By also adding the span that's been created during these calls into the
lookup table, we can properly set the span parent for these requests,
nicely connecting the individual operations to the bigger picture.

a4f65ddba0 feat(tvix/store/bin): add "copy" command
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.

863c4207cc feat(tvix/eval): contextful JSON operations
`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.

Fixes b/393.

We forgot to only write the part of the padding that has not been
written already.

Unfortunately it seems the tokio mocking thing does buffer small writes,
so the tests succeeds even with the bug :-/

63116d8c21 fix(tvix): Avoid buffering file into memory in builtins.hashFile
Right now `builtins.hashFile` always reads the entire file into memory
before hashing, which is not ideal for large files. This replaces
`read_to_string` with `open_file` which allows calculating the hash of
the file without buffering it entirely into memory. Other callers can
continue to buffer into memory if they choose, but they still use the
`open_file` VM request and then call `read_to_string` or `read_to_end`
on the `std::io::Reader`.

Fixes b/380

This adds a Directory service using

Directory (closures) are put in individual keys.

We don't do any bucketed upload of directory closures (yet), as castore/
fs does query individually, does not request recursively (and buffers).
This will be addressed by store composition at some point.

d00c75ea9c fix(nix-compat/store_path): fix Deserialize with borrow
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.

c35a5ff611 feat(users/picnoir/tvix-daemon): parse up to the operation
Using all the primitives recently implemented to nix-compat to reach
the point where the Nix client start to send us operation requests.

Using a small integration test script (or the VM test, but let's face
it, it's too slow to be useful), we manage to reach the point where
we're able to read a store operation:

    2024-03-21T18:53:27.624876Z  INFO tvix_daemon: Incoming connection addr=unix
    2024-03-21T18:53:27.625312Z  INFO worker:perform_init_handshake: tvix_daemon: Trust sent conn=Connection(unix) conn=Connection(unix)
    2024-03-21T18:53:27.625406Z  INFO worker: tvix_daemon: Client hanshake succeeded conn=Connection(unix)
    2024-03-21T18:53:27.625488Z  INFO worker: tvix_daemon: Operation received op=SetOptions conn=Connection(unix)

We had to take some shortcuts wrt. stderr/log management. The CPP Nix
codebase is a bit confusing in that area. I'll need to spend more time
reading this to fully understand what's happening there. For now,
sending the STDERR_LAST command to the client does the trick.

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.

74023a07a4 refactor(tvix/castore/*): drop utils.rs and grpc directorysvc tests
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.

from castore::utils, this will be deleted once it's all ported over.

of latency thanks to gRPC streams bursting, it also enables further
optimizations later (such as bucketing of directory closures).

c92ef2df64 feat(tvix/castore/directory): add ClosureValidator
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.
