[move-compiler-v2] fix #14633: fix error messages for lambdas, identify change points for more complete lambda implementation #14742

brmataptos · 2024-09-24T20:57:54Z

Description

Catch all errors in move-compiler-v2/tests/checking/typing/lambda.move in Compiler V2,
after splitting and gradually commenting out code as lambda[2-5].move,
to avoid shadowing by other errors. Lay groundwork for support of lambdas in various capacities.

Fixes #14633.

add checking for function-typed function results in function_checker, and functions in parameters and results of function types in both args and results to functions there.
Change internal_error to error in bytecode_generator and module_generator
to properly show "error" rather than "bug" if lambdas are mistakenly used as values today.
tag some code to show where changes are needed to support lambda: // TODO(LAMBDA)
fix unused_params_checker and recursive_struct_checker to tolerate lambda types
add experiments to control enabling of various aspects of lambda support:
- LAMBDA_IN_PARAMS, LAMBDA_IN_RETURNS to allow lambdas as general function params or results
- LAMBDA_FIELDS - support lambdas in struct fields
- LAMBDA_VALUES - support lambdas in general-purpose values
- may add LAMBDA_TYPE_PARAMS later
update lambda-lifting test config to use those flags rather than disabling checks
add a result_type_loc field to move-model's FunctionData (and model-builder's FunEntry)
to more precisely locate errors in function result types.
Fix GlobalEnv::internal_dump_env to use function- and struct-specific type contexts
so that types are shown with correct type parameter names.
Check that struct fields are not functions.

How Has This Been Tested?

Running the usual tests.

Key Areas to Review

Note that a few errors are caught quite late, in bytecode-generator,
and the order in which we catch errors may be a bit surprising to
users (errors in exp_builder come first, then errors caught by
function_checker, then (much later) bytecode_generator.).
Actually supporting particular subsets of the "experiments" mentioned
above would be difficult, but it seems useful to have the labels to
help understand just what features are supported by the implementation
as we go.

 type QualifiedFunId = QualifiedId<FunId>;

-/// check that non-inline function parameters do not have function type.
+fn type_has_function(ty: &Type) -> bool {


Might be useful to move this into impl Type, alongside is_function (and we can call is just has_function).

+}
+
+// Takes a list of function types, returns those which have a function type in their argument type
+fn identify_function_types_with_functions_in_args(func_returns: Vec<Type>) -> Vec<Type> {


Because this function a list of function types, could we call the param func_types or even just types? Not clear from the local context why this param is called func_returns.
