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?

The primary constructor for this is now from_bytes, from_string is simply calling .as_bytes() on the string, passing it along. The InvalidName error now contains a Vec<u8>, to encode the invalid name (which might not be a string anymore). from_absolute_path now accepts a &[u8] (even though we might want to make this a OSString of some sort). StorePath::validate_name has been degraded to a pub(crate) function. It's still used in src/derivation, even though it probably shouldn't at all - that cleanup is left for cl/8412 though.

2023-07-11 r/6405 docs(tvix): document when pointer equality is preserved in C++ Nixsterni5-6/+169
This explicitly documents behavior of C++ Nix that goes against the intuition you'd gather from this document: that e.g. a simple select from an attribute set causes a value to no longer be pointer equal to its former self. The point of documenting this is that we can show in a to be written section on the use of pointer equality in nixpkgs that pointer equality is only needed in a limited sense for evaluating it (C++ Nix's exterior pointer equality). Tvix's pointer equality is far more powerful since value identity preserving operations also preserve pointer equality, generally speaking (this is because we implement interior pointer equality in my made up terminology). This should eventually also be documented.

2023-07-11 r/6404 fix(tvix/eval): use byte, not codepoint index for slicing in escapesterni3-1/+12
This fixes a subtle issue which would occasionally lead to a crash (e.g. when evaluating (pkgs.systemd.outPath with --trace-runtime): With each character in the string that has a multi byte representation in UTF-8, the actual byte position and what tvix thought it was would get out of sync. This could either lead to * Tvix swallowing characters or jumbling characters if multi byte characters would cause the tracked index to become out of sync with the byte position before the first character to be escaped, or * Tvix crashing if (in the same situation) the out of sync index would be within a UTF-8 byte sequence. Luckily, std's `char_indices()` iterator implements exactly what `nix_escape_char()`'s original author had in mind with `.chars().enumerate()`. Using `i + 1` for continuing is safe, since all characters that need (in fact, can) to be escaped in Nix are represented as a single byte in UTF-8.

I want to expand on the C++ Nix behavior, since it seems relevant to note that a lot of operations in C++ Nix (like select) don't preserve pointer equality (see <https://github.com/NixOS/nix/issues/3371#issuecomment-1596167957>). It is especially so, as Tvix establishes pointer equality in a different way and thus shows differing behavior. Therefore I want to additionally document Tvix's current behavior and make it more explicit to what extent nixpkgs needs pointer equality.

2023-06-21 r/6341 fix(tvix/eval): use realpaths for import cachesterni8-3/+51
I've noticed this behavior when writing the admittedly cursed test case included in this CL. Alternatively we could use some sort of machinery using `builtins.trace`, but I don't think we capture stderr anywhere. I've elected to put this into the eval cache itself while C++ Nix does it in builtins.import already, namely via `realisePath`. We don't have an equivalent for this yet, since we don't support any kind of IfD, but we could revise that later. In any case, it seems good to encapsulate `ImportCache` in this way, as it'll also allow using file hashes as identifiers, for example. C++ Nix also does our equivalent of canon_path in `builtins.import` which we still don't, but I suspect it hardly makes a difference.

2023-06-20 r/6337 feat(tvix/store/fuse): initial implementationFlorian Klink5-2/+1804
This is a first implementation of a FUSE filesystem, mounting tvix-store to a given location. This is mostly meant as one additional lens into a store, and could be used for builds. It's not meant to be used as a general-purpose thing. It still has some rough edges: - It doesn't implement open/close, so it doesn't use file handles. Which means, we need to open blobs for partial reads over and over again. - It doesn't implement seek, as BlobReader doesn't implement seek yet. - It doesn't track "lifetimes" of inodes by listening on forget, meaning it might hold more data in memory than necessary. - As we don't have store composition (and a caching layer) yet, operations might be slow.

2023-06-20 r/6336 fix(tvix/eval): only finalise formal arguments if defaultingsterni11-56/+235
When dealing with a formal argument in a function argument pattern that has a default expression, there are two different things that can happen at runtime: Either we select its value from the passed attribute successfully or we need to use the default expression. Both of these may be thunks and both of these may need finalisers. However, in the former case this is taken care of elsewhere, the value will always be finalised already if necessary. In the latter case we may need to finalise the thunk resulting from the default expression. However, the thunk corresponding to the expression may never end up in the local's stack slot. Since finalisation goes by stack slot (and not constants), we need to prevent a case where we don't fall back to the default expression, but finalise anyways. Previously, we worked around this by making `OpFinalise` ignore non-thunks. Since finalisation of already evaluated thunks still crashed, the faulty compilation of function pattern arguments could still cause a crash. As a new approach, we reinstate the old behavior of `OpFinalise` to crash whenever encountering something that is either not a thunk or doesn't need finalisation. This can also help catching (similar) miscompilations in the future. To then prevent the crash, we need to track whether we have fallen back or not at runtime. This is done using an additional phantom on the stack that holds a new `FinaliseRequest` value. When it comes to finalisation we check this value and conditionally execute `OpFinalise` based on its value. Resolves b/261 and b/265 (partially).
