2023-12-29 r/7271 fix(tvix/eval): add stack depth assertion to OpReturnAdam Joseph1-0/+7
I'm still trying to work out the exact stack invariants for tvix. We really should add assertions for them; getting the stack messed up is no fun. This commit adds one simple assertion. It also adds a missing stack-push (my mistake) in one place, which was uncovered by the assertion.

2023-12-25 r/7264 fix(tvix/eval/value): correctly emit spaces when coercing listssterni3-16/+36
r/7176 introduced an incorrect assumption was the benefit of the nonrecursive coercion algorithm, namely that a coercion operation always returns a non empty string. This allows to detect whether we are coercing a list or not by checking if the intermediate result is empty or not. Unfortunately, coercing null and false yields an empty string, so we need to explicitly track whether we are coercing a list. Updated the test case to hopefully catch similar bugs in the future. I'm not a hundred percent certain I have not introduced a new edge case with this, so it may be interesting to add a prop test case for this to nix_oracle down the line. At least lists are the only nested data structures that can be serialized as nested data structures, so the problem is kind of limited.

2023-12-22 r/7256 chore(tvix): move store/fs to castore/fsFlorian Klink18-199/+257
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.

There's nothing store-path specific here anymore, it's just a name in the mountpoint root. Change-Id: I0f8004491baa03ba560d390053a42678ee81154a Reviewed-on: https://cl.tvl.fyi/c/depot/+/10377 Autosubmit: flokli <flokli@flokli.de> Tested-by: BuildkiteCI Reviewed-by: raitobezarius <tvl@lahfa.xyz>
2023-12-16 r/7225 docs(tvix): refer to futures-rs PRFlorian Klink1-0/+1
The PR has since been replaced with another version, using a bit of unsafe, as rustc doesn't like the lifetimes. We're still waiting on a backport of that to 0.3.

2023-12-14 r/7222 refactor(tvix/store/fs): Decouple TvixStoreFs from Nix conceptsConnor Brewster2-76/+119
To support tvix builds, we need to be able to use the `TvixStoreFs` to materialize the sandbox's /nix/store filesystem with just the list of inputs needed for the build. Currently we'd need to seed an in-memory `PathInfoService`, which includes more functionality than what is required for `TvixStoreFs`. Additionally, the `PathInfoService` is specific to Nix. By decoupling `TvixStoreFs` and `PathInfoService`, we allow for usage of `TvixStoreFs` with `tvix-castore` without needing a `PathInfoService`. This introduces a new `RootNodes` trait which provides a way for the filesystem to look up CA nodes via their basename in the root directory of the filesystem. We then implement `RootNodes` for any `PathInfoService`. Additionally, the filesystem root inode tracker now stores basenames rather than `StorePath`s since `StorePath`s are specific to Nix. As a followup we can rename `TvixStoreFs` to `TvixCaStoreFs` and move it to the `castore` crate (or its own crate). b/341 Change-Id: I928372955017c23b1bf2b37190cbc508a4ed10d5 Reviewed-on: https://cl.tvl.fyi/c/depot/+/10363 Tested-by: BuildkiteCI Reviewed-by: flokli <flokli@flokli.de>
