Instead, it's passed in the evaluate/compile_only functions, which feels more naturally. It lets us set up the Evaluation struct long before we actually feed it with data to evaluate. Now that Evaluation::new() would be accepting an empty list of arguments, we can simply implement Default, making things a bit more idiomatic.

2023-12-29 r/7282 feat(tvix/eval): context-aware casting to stringsRyan Lahfa1-2/+23
By default, we don't want contextful strings and we almost always want contextless strings. To this end, we make taking a contextful string a very explicit operation under `to_contextful_str` and we implement manually the `to_str` cast which requires a `if !s.has_context()` guard that the macro cannot cover.

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.

2023-12-14 r/7218 fix(tvix/eval): remove incorrect imports when coercingsterni7-49/+193
The default behavior of string coercion in C++ Nix is to weakly coerce and import to store if necessary. There is a flag to make it strongly coerce (coerceMore) and a flag that controls whether path values have the corresponding file/directory imported into the store before returning the (store) path as a string (copyToStore). We need to implement our equivalent to the copyToStore (import_paths) flag for the benefit of weak coercions that don't import into the store (dirOf, baseNameOf, readFile, ...) and strong coercions that don't import into the store (toString). This makes coerce_to_string as well as CoercionKind weirder and more versatile, but prevents us from reimplementing parts of the coercion logic constantly as can be seen in the case of baseNameOf. Note that it is not possible to test this properly in //tvix/eval tests due to the lack of an appropriate EvalIO implementation being available. Tests should be added to //tvix/glue down the line.

2023-12-12 r/7178 fix(tvix/eval): fix branching on catchable defaults (b/343)Adam Joseph6-0/+20
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. There are probably other places where we need to do the same thing.

This is a test case for b/343, wherein tvix dies if you try to branch on an argument whose defaulted value is a catchable.

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/7175 feat(tvix/eval): nonrecursive deep_force()Adam Joseph5-80/+82
This commit implements deep_force() nonrecursively, by maintaining an explicit stack rather than using the call stack for recursion. As an added bonus, we don't need to pass around the SharedThunkSet anymore, and can in fact completely eliminate SharedThunkSet.
