2023-11-05 r/6957 refactor(tvix/eval): use IntoIterator trait for owned NixAttrs iterVincent Ambo1-15/+22
Uses the standard library IntoIterator trait for the construction of our iterators. Clippy complains about duplicating this. While doing this, I opted to rename the `IntoIter` type into something that is more useful to users, in case somebody ends up working with these manually. This fixes a clippy lint, and is related to b/321.

2023-11-03 r/6930 refactor(tvix/eval): more efficiently intersect attributesVincent Ambo1-9/+70
builtins.intersectAttrs is used a _lot_ in nixpkgs eval, for whatever reason. We previously had a very inefficient implementation that would allocate for each comparison. It stuck out like a sore thumb in perf analysis. This moves to a custom algorithm with two iterators, one for the left and one for the right side, advancing them along the (borrowed) map keys until a match is found and allocation is required. I've not made any effort to reduce the verbosity of this code, I don't think it's worth it. On my machine this reduces the mean runtime of evaluating `nixpkgs.emacs.outPath` by ~8%.

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.

2023-07-11 r/6405 docs(tvix): document when pointer equality is preserved in C++ Nixsterni4-5/+39
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'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/6336 fix(tvix/eval): only finalise formal arguments if defaultingsterni9-52/+231
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).

2023-06-15 r/6309 test(tvix/eval): genericClosure (pointer) comparison supportsterni4-0/+37
genericClosure has very limited support for pointer equality: It relies on comparison (not equality!) in C++ Nix, so as soon as C++ Nix supports comparing lists (langVersion >= 6) we can rely on pointer equality for key. Since Tvix uses equality, not comparison for the insert, our behavior is currently different, as documented by the notyetpassing tests.

2023-06-15 r/6308 fix(tvix/eval): make tvix display values like nix-instantiate(1)sterni8-3/+59
In order for the test suite we have currently to be comparable to C++ Nix, we need to display values in the same way. This was largely the case except in some weird cases. * <CODE> for thunks and <CYCLE> for repeated thunks (?) are already in use. <CODE> formatting is tested by the oracle test suite already. * Instead of lambda, we need to use <LAMBDA> * <<primop>> and <<primop-app>> (a formatting C++ Nix uses nowhere) now are <PRIMOP> and <PRIMOP-APP>. We'll probably want to have a fancier display of values (in a separate trait) down the line. This could be used for interactive usage, e.g. the REPL or a potential debugger. There is a peculiarity with C++ Nix 2.3 formatting primops: import is considered a <<PRIMOP-APP>>, since it is internally implemented by means of scopedImport. This implementation detail no longer leaks in C++ Nix 2.13 nor in Tvix. <CYCLE> display is untested at the moment, since we exhibit a discrepancy to C++ Nix 2.3. Our current detection is more similar to C++ Nix 2.13—luckily it is also the more consistent of the two. See also b/245.

2023-06-14 r/6297 fix(tvix/eval): don't thunk home relative pathssterni2-11/+13
C++ Nix resolves home relative paths at [parse] time. This is not an option for us, since it prevents being able to separate the compilation and execution phase later (e.g. precompiled nix expressions). However, a practical consequence of this is that paths expressions are always literals (strict) and never thunks.
