2024-04-15 r/7931 refactor(tvix/castore/fs): remove From<Node> for InodeDataFlorian Klink1-64/+33
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.

2024-04-15 r/7919 feat(tvix/castore/fs): assign read[dir*]/release[dir] ops to parent spanFlorian Klink1-13/+20
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.

2024-04-15 r/7917 feat(tvix/castore/fs): implement readdirplusFlorian Klink1-1/+126
This currently shares some code with readdir, except it's also providing a second `fuse_backend_rs::api::filesystem::Entry` argument to the `add_entry` function call. Refactoring this to reduce some duplication is left for a future CL.

Also update the comment, we don't get ownership, just simply drop, and change the level to warn!, as suggested in cl/11425.

2024-04-15 r/7915 feat(tvix/castore/fs): implement opendir/releasedirFlorian Klink1-60/+142
Similar to how we already handle opening files, implement opendir/ releasedir, and keep a map of dir_handles. They point to the rx side of a channel. This greatly improves performance listing the root of the filesystem when used inside tvix-store, as we don't need to re-request the listing (and skip to the desired position) all the time.

cl/10378 did already move store/fs to castore/fs, but we kept the tests in tvix-store, as they were populating a PathInfoService to make nodes appear in the mount root.

2023-12-22 r/7256 chore(tvix): move store/fs to castore/fsFlorian Klink1-0/+627
With the recent introduction of the RootNodes trait, there's nothing in the fs module pulling in tvix-store dependencies, so it can live in tvix-castore. This allows other crates to make use of TvixStoreFS, without having to pull in tvix-store. For example, a tvix-build using a fuse mountpoint at /nix/store doesn't need a PathInfoService to hold the root nodes that should be present, but just a list. tvix-store now has a pathinfoservice/fs module, which contains the necessary glue logic to implement the RootNodes trait for a PathInfoService. To satisfy Rust orphan rules for trait implementations, we had to add a small wrapper struct. It's mostly hidden away by the make_fs helper function returning a TvixStoreFs. It can't be entirely private, as its still leaking into the concrete type of TvixStoreFS. tvix-store still has `fuse` and `virtiofs` features, but they now simply enable these features in the `tvix-castore` crate they depend on. The tests for the fuse functionality stay in tvix-store for now, as they populate the root nodes through a PathInfoService. Once above mentioned "list of root nodes" implementation exists, we might want to shuffle this around one more time. Fixes b/341.
