This commit adds Opcode::OpJumpIfCatchable, which can be inserted ahead of most VM operations which expect a boolean on the stack, in order to handle catchables in branching position properly. Other than remembering to patch the jump, no other changes should be required. This commit also fixes b/343 by emitting this new opcode when compiling if-then-else.

2023-12-12 r/7176 feat(tvix/eval): nonrecursive coerce_to_string()Adam Joseph6-121/+138
After this commit, the only non-builtins uses of generators are: - coerce_to_string() uses generators::request_enter_lambda() - Thunk::force() uses generators::request_enter_lambda() That's it! Once those two are taken care of, GenCo can become an implementation detail of `builtins::BuiltinGen`. No more crazy nonlocal flow control within the interpreter: if you've got a GenCo floating around in your code it's because you're writing a builtin, which isn't part of the core interpreter. The interpreter won't need GenCos to talk to itself anymore. Technically generators::request_path_import() is also used by coerce_to_string(), but that's just because the io_handle happens to be part of the VM. There's no recursion-depth issue there, so the call doesn't need to go through the generator mechanism (request_path_import() doesn't call back to the interpreter!)

2023-12-12 r/7172 feat(tvix/eval): drop LightSpan::DelayedAdam Joseph2-13/+1
LightSpan::Delayed was introduced in commit bf286a54bc2ac5eeb78c3d5c5ae66e9af24d74d4 which claimed that "This reduces the eval time for `builtins.length (builtins.attrNames (import <nixpkgs> {}))` by *one third*!" I am unable to reproduce this result. In fact, dropping the LightSpan::Delayed variant of the enum makes eval of the same expression slightly faster! I also tried a large evaluation (pkgsCross...hello) and got similar results: slightly faster, slightly less memory. See git footers. I suspect that there was some unrelated horrific inefficiency that has since been fixed. The avoided computation in `get_span()` is nothing more than a binary search! If this were in fact a major performance issue we could simply precompute the mapping from CodeIdx to Span when the Chunk becomes immutable (i.e. at the end of the compilation process, when compiler backtracking is no longer a concern). Since a Span is just 64 bits this is not a space issue, and since binary search is much simpler than compiling Nix expressions it isn't a performance issue either. Technically there is no longer any reason to have LightSpan since it is now a single-variant enum. However there is no rush to remove it, since Rust will optimize its representation into the same thing you'd get if you replaced LightSpan by Span.

2023-12-12 r/7166 fix(tvix/eval): never use partial_cmp() (partial fix b/338)Adam Joseph3-23/+16
This is part of a fix for b/338. We should never use PartialOrd::partial_cmp(). All Nix types except floats are obviously totally-ordered. In addition, it turns out that because Nix treats division by zero rather than producing a NaN, and because it does not support "negative zero", even floats are in fact totally ordered in Nix. Therefore, every call to PartialOrd::partial_cmp() in tvix is an error. We have to *implement* this function, but we should never call it on built-in types. Moreover, nix_cmp_ordering() currently returns an Option<Ordering>. I'm not sure what was going on there, since it's impossible for it to return None. This commit fixes it to return simply Ordering rather than Option<Ordering>.

2023-12-06 r/7120 feat(tvix/eval): rewrite Thunk::force() in nonrecursive formAdam Joseph3-64/+97
This commit rewrites Thunk::force() so that it is not (directly) self-recursive. It maintains a Vec of all the previously-encountered thunks which point to the one it is currently forcing, rather than recursively calling itself. Benefits: - Short term: This commit saves the cost of a round-trip through the generator machinery for the generators::request_force() which is removed by this commit. - Medium term: Once a similar transformation has been applied to nix_cmp(), nix_add(), nix_eq(), and coerce_to_string(), those four functions, along with Thunk::force(), will make non-tail calls only to each other. They can then be merged into a single tail-recursive function which does not use the generator machinery at all: enum Task { Cmp, Add, Eq, CoerceToString, Force}; fn Value::walk(task:Task, v1:Value, v2:Value) { // ... - Long term: The long-term goal here is to use generators **only for builtins** and [Marionette]-style remote control of the VM. In other words: use `async` for things that actually involve concurrency. Calls from the VM to builtins can then be blocking calls, because even cppnix will overflow the stack if you make a MAX_STACK_DEPTH-deep recursive call which passes through a builtin at every stack frame (e.g. `{ func = builtins.sort (a: b: ... func ...) ...}`). This way the inner "tight loop" of the interpreter doesn't pay the costs of `async` and generators. These costs manifest in terms of: performance, complex nonlocal control flow, and language impediments (async Rust is a restricted subset of real Rust, and is missing things like traits).

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%.

This commit makes catchable errors a variant of Value. The main downside of this approach is that we lose the ability to use Rust's `?` syntax for propagating catchable errors.

In cppnix 2.17, commit b72bc4a972fe568744d98b89d63adcd504cb586c, the libexpr pretty-printing routine was fixed so that it would no longer pretty-print attrsets with keywords in their attrnames incorrectly. This commit implements the corresponding fix for tvix, fixes our tests to work with cppnix>=2.17 oracles, and expands our test cases to cover all the keywords.
