d2e67f021e refactor(tvix/castore): add separate Error enum for archives
The `Error` enum for the `imports` crate has both filesystem and archive
specific errors and was starting to get messy.

This adds a separate `Error` enum for archive-specific errors and then
keeps a single `Archive` variant in the top-level import `Error` for all
archive errors.

79698c470c feat(tvix/castore): upload blobs concurrently when ingesting archives
Ingesting tarballs with a lot of small files is very slow because of the
round trip time to the `BlobService`. To mitigate this, small blobs can
be buffered into memory and uploaded concurrently in the background.

5fc403587f refactor(tvix/castore): ingest filesystem entries in parallel
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.

18ab59ed70 fix(tvix/castore): ensure all directories are present during ingestion
`ingest_entries` requires that all directories referenced by entries in
the ingestion stream have an explicit entry in the stream.

For example, if the stream contains a file with path `foo/bar`, there
must be an entry that comes later in the stream for the directory `foo`.

3107961428 feat(tvix/eval): Implement builtins.fetchTarball
Implement a first pass at the fetchTarball builtin.

This uses much of the same machinery as fetchUrl, but has the extra
complexity that tarballs have to be extracted and imported as store
paths (into the directory- and blob-services) before hashing. That's
reasonably involved due to the structure of those two services.

This is (unfortunately) not easy to test in an automated way, but I've
tested it manually for now and it seems to work:

259d7a3cfa refactor(tvix/castore): generalize store ingestion streams
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.

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.

bcc00fba8f refactor(tvix/castore/import): inline process_entry
This did very little, and especially the part of relying on the outside
caller to pass in a Directory if the type is a directory required having
per-entry-type specific logic anyways.

It's cleaner to just inline it.

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.

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.

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.

Log the entire span with "trace" level, not just its `ret` level.

The level of the error value event defaults to ERROR, so we don't loose
these.

B3Digest implements Debug and Display the same way, so we can omit the
`(Display)` part in `ret(Display)` for them.

2798803f76 refactor(tvix/castore): introduce "cloud" feature flag
This controls whether tvix-castore has support for various cloud
backends or not.

Use this to control the set of feature flags for the object_store
backend, and only enable the aws, azure and gcp ones if it's set.
In the future this can be used to enable/disable other cloud backends
too.

Without feature flags, `object_store` already supports the `InMemory`
and `LocalFilesystem` backends, and we also want to unconditionally
enable the `http` one. Make sure at least the construction of these
services is covered in the tests.

Similarly, the tvix-store crate, which provides the tvix-store CLI has a
`cloud` feature flag too (defaulting to enabled).

82f8ce8b7d feat(tvix/castore/blobsvc/grpc): read data in chunks
Whenever this encounters an open_read(), it'll first check for more
granular chunking. If there's more granular chunking data available, a
ChunkedReader is constructed (which supports seeking backwards).

This currently is still a bit stupid, and doesn't compose, as
`ChunkedReader` uses `self` as the `BlobService` to ask for the
individual chunks.

In store composition future, we might want to compose this differently,
essentially constructing `ChunkedReader` with another `BlobService`
representing the entire hierarchy, so there's a chance to locally cache
things, and do less requests.

fdf9657654 fix(tvix): don't emit rerun-if-changed
`build.rs` emits rerun-if-changed statements for all proto files, as
well as all include paths we pass it.

Unfortunately, due to protobufs include path rules, we need to specify
the path to the depot root itself as an include path, at least when
building impurely with `cargo`. This causes cargo to essentially always
rebuild, as it also puts its own temporary files in there.

Unfortunately, tonic-build does not chase down to individual .proto
files that are included.

Disable emitting these `rerun-if-changed` statements for now.

This could cause cargo to not rebuild protos every time, causing stale
data until the next local `cargo clean`, but considering the protos
change not that frequently, and it'll immediately surface if trying to
build via Nix (either locally or in CI), it's a good-enough compromise.
