2023-09-05 r/6557 feat(tvix/store): fix ctrl-c handling on mount commandFlorian Klink1-3/+24
This enables the tokio `signal` feature, and registers a ctrl_c signal handler, which will use the unmount handle to unmount in case a ctrl-c signal is received. This avoids having disconnected mountpoints when Ctrl-C'ing a `tvix-store mount` invocation. In case the filesystem is unmounted externally (via `umount /path/to/ mountpoint`), the future is waiting for the signal is never resolved and the task is stopped.

2023-09-04 r/6550 refactor(tvix/{cli,store}): move TvixStoreIO to tvix-cli crateFlorian Klink1-12/+55
This trait is eval-specific, there's no point in dealing with these things in tvix-store. This implements the EvalIO interface for a Tvix store. The proper place for this glue code (for now) is tvix-cli, which knows about both tvix-store and tvix-eval. There's one annoyance with this move: The `tvix-store import` subcommand previously also used the TvixStoreIO implementation (because it conveniently did what we wanted). Some of this code had to be duplicated, mostly logic to calculate the NAR-based output path and create the PathInfo object. Some, but potentially more of this can be extracted into helper functions in a shared crate, and then be used from both TvixStoreIO in tvix-cli as well as the tvix-store CLI entrypoint.

2023-07-21 r/6436 refactor(tvix/store): use bytes for node names and symlink targetsFlorian Klink1-4/+4
Some paths might use names that are not valid UTF-8. We should be able to represent them. We don't actually need to touch the PathInfo structures, as they need to represent StorePaths, which come with their own harder restrictions, which can't encode non-UTF8 data. While this doesn't change any of the wire format of the gRPC messages, it does however change the interface of tvix_eval::EvalIO - its read_dir() method does now return a list of Vec<u8>, rather than SmolStr. Maybe this should be OsString instead?

This operation is blocking, so it should be run inside a blocking tokio task. Tokio panics if it detects a blocking operation inside a non- blocking task, so cl/8619 would cause it to panic (as the GRPC clients use spawn_blocking under the hood). As spawn_blocking moves, and we can't clone `TvixStoreIO` (see cl/8614), we create a new instance of TvixStoreIO inside each loop iteration.

2023-05-11 r/6133 refactor(tvix/store): remove ChunkServiceFlorian Klink1-12/+2
Whether chunking is involved or not, is an implementation detail of each Blobstore. Consumers of a whole blob shouldn't need to worry about that. It currently is not visible in the gRPC interface either. It shouldn't bleed into everything. Let the BlobService trait provide `open_read` and `open_write` methods, which return handles providing io::Read or io::Write, and leave the details up to the implementation. This means, our custom BlobReader module can go away, and all the chunking bits in there, too. In the future, we might still want to add more chunking-aware syncing, but as a syncing strategy some stores can expose, not as a fundamental protocol component. This currently needs "SyncReadIntoAsyncRead", taken and vendored in from https://github.com/tokio-rs/tokio/pull/5669. It provides a AsyncRead for a sync Read, which is necessary to connect our (sync) BlobReader interface to a GRPC server implementation. As an alternative, we could also make the BlobReader itself async, and let consumers of the trait (EvalIO) deal with the async-ness, but this is less of a change for now. In terms of vendoring, I initially tried to move our tokio crate to these commits, but ended up in version incompatibilities, so let's vendor it in for now.
