2024-04-15 r/7914 refactor(tvix/castore/fs): use std::sync::MutexFlorian Klink1-21/+24
This allows us acquiring the lock in sync code still. Also, simplify some of the error handling a bit.

2024-04-15 r/7913 refactor(tvix/castore/fs): simplify some separate spawn and blocksFlorian Klink1-13/+6
We can just pass an async move closure to `self.tokio_handle.block_on` and make this a bit shorter.

This exposes `user.tvix.castore.{blob,directory}.digest` xattr keys for files and directories: ``` ❯ getfattr -d /tmp/tvix/06jrrv6wwp0nc1m7fr5bgdw012rfzfx2-nano-7.2-info getfattr: Removing leading '/' from absolute path names user.tvix.castore.directory.digest="b3:SuYDcUM9RpWcnA40tYB1BtYpR0xw72v3ymhKDQbBfe4=" ❯ getfattr -d /tmp/tvix/156a89x10c3kaby9rgf3fi4k0p6r9wl1-etc-shells getfattr: Removing leading '/' from absolute path names user.tvix.castore.blob.digest="b3:pZkwZoHN+/VQ8wkaX0wYVXZ0tV/HhtKlSqiaWDK7uRs=" ``` It's currently mostly used for debugging, though it might be useful for tvix-castore-aware syncing programs using the filesystem too.

There's no need to pass in an unused directory service into the populate_blob_* method, and considering we have one or two invocation of each of these, we don't really gain much from having all these functions follow the same structure, at least for now. Also, update some function names to better describe what they're doing.

2023-12-24 r/7258 refactor(tvix/castore): add RootNode impl for BTreeMap, mv fs testsFlorian Klink3-2/+1183
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. Update these tests to now just insert root nodes into a BTreeMap, and ensure we can use that as a RootNodes too.

2023-12-22 r/7256 chore(tvix): move store/fs to castore/fsFlorian Klink7-0/+1312
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.
