2024-05-04 r/8073 refactor(tvix/*store): use DS: DirectoryServiceFlorian Klink1-2/+2
We implement DirectoryService for Arc<DirectoryService> and Box<DirectoryService>, this is sufficient. Change-Id: I0a5a81cbc4782764406b5bca57f908ace6090737 Reviewed-on: https://cl.tvl.fyi/c/depot/+/11586 Tested-by: BuildkiteCI Reviewed-by: Connor Brewster <cbrewster@hey.com>
2024-05-02 r/8067 refactor(tvix/castore/import): use crate Path[Buf] in IngestionEntryFlorian Klink1-19/+5
This explicitly splits ingestion-method-specific path types from the castore types. Change-Id: Ia3b16105fadb8d52927a4ed79dc4b34efdf4311b Reviewed-on: https://cl.tvl.fyi/c/depot/+/11563 Autosubmit: flokli <flokli@flokli.de> Reviewed-by: Connor Brewster <cbrewster@hey.com> Tested-by: BuildkiteCI
2024-04-30 r/8048 refactor(tvix/castore/import): restructure error typesFlorian Klink1-5/+15
Have ingest_entries return an Error type with only three kinds: - Error while uploading a specific Directory - Error while finalizing the directory upload - Error from the producer Move all ingestion method-specific errors to the individual implementations.

2024-04-30 r/8047 refactor(tvix/castore): remove IngestionEntry::UnknownFlorian Klink1-9/+0
We shouldn't try to represent non-representable things in the ingestion entries (only to throw an error). It's cleaner to throw the error directly in the part producing the stream.

This is only useful for when we have access to a filesystem, so it shouldn't be in the root. Change-Id: I9923aaed1aef9d3a1e8fad41f58821d51c2eb34b Reviewed-on: https://cl.tvl.fyi/c/depot/+/11555 Autosubmit: flokli <flokli@flokli.de> Reviewed-by: firefly <firefly@firefly.nu> Tested-by: BuildkiteCI
2024-04-30 r/8045 fix(tvix/castore/import): symlink targets are Vec<u8>Florian Klink1-2/+2
These can be arbitrary bytes in theory. Some of our libraries might be more strict, or inconsistent w.r.t. their representation of path separators.

2024-04-23 r/8000 refactor(tvix/castore): switch to `ingest_entries` for tarball ingestionConnor Brewster1-0/+5
With `ingest_entries` being more generalized, we can now use it for ingesting the directory entries generated from tarballs.

2024-04-20 r/7987 refactor(tvix/castore): ingest filesystem entries in parallelFlorian Klink1-10/+7
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.

2024-04-20 r/7984 fix(tvix/castore): ensure all directories are present during ingestionConnor Brewster1-0/+8
`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`.

2024-04-20 r/7983 feat(tvix/eval): Implement builtins.fetchTarballAspen Smith1-1/+1
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: tvix-repl> (import ../. {}).third_party.nixpkgs.hello.outPath => "/nix/store/dbghhbq1x39yxgkv3vkgfwbxrmw9nfzi-hello-2.12.1" :: string Co-authored-by: Connor Brewster <cbrewster@hey.com> Change-Id: I57afc6b91bad617a608a35bb357861e782a864c8 Reviewed-on: https://cl.tvl.fyi/c/depot/+/11020 Autosubmit: aspen <root@gws.fyi> Reviewed-by: flokli <flokli@flokli.de> Tested-by: BuildkiteCI
