2024-03-11 r/7684 feat(tvix/castore/blobsvc): add object storage implementationFlorian Klink3-0/+561
This uses the `object_store` crate to expose a tvix-castore BlobService backed by object storage. It's using FastCDC to chunk blobs into smaller chunks when writing to it. These are exposed at the .chunks() method.

2024-03-03 r/7648 refactor(tvix/*/from_addr): improve test debuggabilityFlorian Klink1-2/+6
If there's an unexpected test failure, print it out, rather than just saying something is false even though it should be true. Use .expect() for this, which displays the error if it failed. We can't use expect_err(), as our stores are not display'able, so use an assertion with a message there.

2024-03-03 r/7631 refactor(tvix/castore/blobsvc/chunked_reader): refactor, documentFlorian Klink1-131/+139
The public-consumable thing here is ChunkedReader, not ChunkedBlob. ChunkedBlob is a helper that can be used to get a new AsyncRead, but not AsyncSeek. It is used internally by ChunkedReader whenever the client seeks. Make this more obvious, by extending the documentation, and putting ChunkedReader at the top of this file. Also make ChunkedBlob and its methods private, and give ChunkedReader a more useful constructor (from_chunks, instead of from_chunked_blob).

These provide seekable access into a Blob for which we have more granular chunking information. There's no support for verified streaming in here yet, this simply produces a stream of readers for each chunk, skipping irrelevant chunks and data from the first chunk at the beginning. A seek simply does produce a new reader using the same process.

2024-01-09 r/7365 feat(tvix/castore/blobsvc): add chunks methodFlorian Klink2-2/+47
This adds support to retrieve a list of chunks for a given blob to the BlobService interface. While theoretically all chunk-awareness could be kept private inside each BlobService reader, we'd not be able to resolve individual chunks from different Blobservices - and due to this, not able to substitute chunks we already have in a more local store. This function allows asking a BlobService for the list of chunks, leaving any actual fetching up to the caller (be it through individual calls to open_read), or asking another store for it.

2023-12-11 r/7158 chore(tvix): drop sled compression supportFlorian Klink2-2/+4
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).
