2023-01-31 r/5795 fix(tvix/eval): allow builtins.toXML to serialise any functionVincent Ambo1-1/+13
This adds a fake argument name to builtins.toXML which allows toXML to serialise any value instead of panicking on functions. We do still have to fix the value itself, eventually, though.

While it is in the given example, i.e. for integer addition, to claim that they are equivalent is a bit misleading: builtins.add is less overloaded than +, i.e. builtins.add "foo" "bar" will fail whereas "foo" + "bar" performs string concatenation.

2023-01-25 r/5753 feat(tvix/eval): use lexical-core to format floatFlorian Klink4-4/+90
Apparently our naive implementation of float formatting, which simply used {:.5}, and trimmed trailing "0" strings not sufficient. It wrongly trimmed numbers with zeroes but no decimal point, like `10000` got trimmed to `1`. Nix uses `std::to_string` on the double, which according to https://en.cppreference.com/w/cpp/string/basic_string/to_string is equivalent to `std::sprintf(buf, "%f", value)`. https://en.cppreference.com/w/cpp/io/c/fprintf mentions this is treated like this: > Precision specifies the exact number of digits to appear after > the decimal point character. The default precision is 6. In the > alternative implementation decimal point character is written even if > no digits follow it. For infinity and not-a-number conversion style > see notes. This doesn't seem to be the case though, and Nix uses scientific notation in some cases. There's a whole bunch of strategies to determine which is a more compact notation, and which notation should be used for a given number. https://github.com/rust-lang/rust/issues/24556 provides some pointers into various rabbit holes for those interested. This gist seems to be that currently a different formatting is not exposed in rust directly, at least not for public consumption. There is the [lexical-core](https://github.com/Alexhuszagh/rust-lexical) crate though, which provides a way to format floats with various strategies and formats. Change our implementation of `TotalDisplay` for the `Value::Float` case to use that. We still need to do some post-processing, because Nix always adds the sign in scientific notation (and there's no way to configure lexical-core to do that), and lexical-core in some cases keeps the trailing zeros. Even with all that in place, there as a difference in `eval-okay- fromjson.nix` (from tvix-tests), which I couldn't get to work. I updated the fixture to a less problematic number. With this, the testsuite passes again, and does for the upcoming CL introducing builtins.fromTOML, and enabling the nix testsuite bits for it, too.

2023-01-21 r/5721 refactor(tvix/eval): administer antidote for poisonAdam Joseph8-135/+49
The codebase contains a lot of complexity and odd roundabout handling for shadowing globals. I'm pretty sure none of this is necessary, and all of it disappears if you simply make the globals part of the ordinary identifier resolution chain, with their own scope up above the root scope. Then the ordinary shadowing routines do the right thing, and no special cases or new terminology are required. This commit does that. Note by tazjin: This commit was originally abandoned when Adam decided not to take away reviewer bandwidth for this at the time (eval was still in a much earlier stage). As we've recently done some significant refactoring of globals initialisation this came up again, and it seems we can easily cover the use-cases of the poison tracking in other ways now, so I've rebased, updated and resurrected the CL.

This is a somewhat terrifying hack that enables us to support `builtins.builtins`, by running a "fake compilation" inside of a suspended native thunk that can resolve the weak pointer to the globals. With this implementation, the thunk at `builtins.builtins` actually resolves to the "real" `builtins` (verified with a new test). This is kind of ugly, and it's something users shouldn't use, but bubbling a warning out of this is difficult at the moment due to a little bit of trickery with how the spans in suspended native thunks work (they don't) (see b/237, b/238) Change-Id: I67d0e93246dd5b279c960aeda00402031aa12af3 Reviewed-on: https://cl.tvl.fyi/c/depot/+/7748 Tested-by: BuildkiteCI Reviewed-by: flokli <flokli@flokli.de>

2023-01-06 r/5601 refactor(tvix/eval): take owned ast::Expr in Compiler::compileVincent Ambo2-34/+34
This adds a very minimal amount of additional Rc-increments (~1 per compilation), but makes it a lot easier to add an AST-optimising compiler pass without incurring a lot of extra cost.

2023-01-06 r/5599 feat(tvix/eval): add Evaluation::compile_only methodVincent Ambo2-47/+99
This would make it possible to implement something like a linter based on the tvix-eval compiler warnings. Change-Id: I1feb4e7c4a44be7d1204b0a962ab522fd32b93c6 Reviewed-on: https://cl.tvl.fyi/c/depot/+/7763 Tested-by: BuildkiteCI Reviewed-by: flokli <flokli@flokli.de>
2023-01-06 r/5598 fix(tvix/eval): don't increase `with_stack_size` in scope inheritsVincent Ambo1-1/+1
There was probably a misunderstanding somewhere about the with_stack_size being related to how far away it is from the with, but it is about whether there is a with at all. This broke a warning (`UselessInherit`), and may actually have let to more inefficient codegen in some cases.
