BE-587, BE-588: HashQL: Introduce `CodeGenerationContext`/`CodeExecutionContext` split and eval-stage `Interner` by indietyp · Pull Request #8839 · hashintel/hash

indietyp · 2026-06-08T11:41:48Z

🌟 What is the purpose of this PR?

This PR refactors the HashQL evaluation pipeline to introduce a cleaner separation between the code generation phase and the code execution phase. The previously unified EvalContext is split into CodeGenerationContext (used during MIR compilation and Postgres query preparation) and CodeExecutionContext (used during orchestrated query execution). This makes the data flow and lifecycle of each phase explicit and prevents accidental misuse of context across phase boundaries.

Additionally, a dedicated eval::intern::Interner is introduced for the evaluation stage, which must be constructed from the MIR interner via From to preserve interned pointer identity across the MIR/eval boundary. Input construction for orchestrator tests is also migrated away from using the JSON decoder to directly building typed Value trees using the heap allocator, removing a dependency on the type environment at input-construction time.

The compile_query implementation in the graph API is stubbed out with unimplemented! pending the HashQL API wire-up tracked in BE-537.

🔍 What does this change?

Renames EvalContext to CodeGenerationContext and introduces a new CodeExecutionContext struct that is produced from CodeGenerationContext via From, carrying only the fields needed at execution time.
Adds eval::intern::Interner as a dedicated interner for the evaluation stage, constructed from hashql_mir::intern::Interner to preserve pointer identity.
Updates Orchestrator and PostgresCompiler to use the appropriate context type for their respective phases.
Replaces JSON-decoder-based input construction in orchestrator tests with direct Value tree construction using heap-allocated Rc and StructBuilder, removing the dependency on the post-lowering type environment for building inputs.
Stubs out EntityQuery::compile_query with unimplemented! and suppresses dead_code warnings pending the full HashQL API integration.
Updates the EvalDiagnosticCategory enum to replace the graph-feature-gated Graph variant with an Orchestrator variant backed by OrchestratorDiagnosticCategory.
Migrates orchestrator test helpers to pass Lowered by value (consuming it) and convert the MIR interner into the eval interner at the appropriate pipeline stage.

🛡 What tests cover this?

Existing orchestrator integration tests and eval_postgres compile tests exercise the refactored context types and input construction.
Decoder unit tests updated to use Interner::testing for the new eval-stage interner.

❓ How to test this?

Run cargo test across the hashql-eval and hash-graph-api crates.
Run the orchestrator integration tests to confirm query execution still produces correct results against a live Postgres instance.

PR Summary

Medium Risk
Raw HashQL query entity/subgraph requests are broken until BE-537; eval/orchestrator wiring and allocator changes touch the main query execution path.

Overview
Refactors the HashQL eval pipeline so Postgres compilation and orchestrated execution use distinct context types, and temporarily disables in-API compilation of raw HashQL entity queries.

EvalContext is renamed to CodeGenerationContext (live-out analysis, diagnostics, allocator) and CodeExecutionContext is added for the orchestrator with only env, interner, bodies, execution residuals, and alloc. Execution context is produced via From after codegen finishes.

A new hashql_eval::intern::Interner is introduced and must be built from the MIR interner so symbol interning stays pointer-identical across the MIR/eval boundary; decoders, partial hydration, and Postgres compilers now take this type instead of hashql_mir::intern::Interner.

EvalDiagnosticCategory drops the feature-gated Graph variant in favor of Orchestrator.

In entity_query_request, the full AST→HIR→graph-read compile path for EntityQuery::Query is removed; those requests now return 501 NOT_IMPLEMENTED with a BE-537 link (filter queries unchanged).

Orchestrator integration tests build interpreter Inputs by constructing opaque Value trees on the heap (and use run_in with the heap allocator) instead of type-environment JSON decoding.

Pull request overview

Refactors the HashQL evaluation pipeline to explicitly separate code-generation vs code-execution concerns by splitting the former EvalContext into CodeGenerationContext and CodeExecutionContext, and introduces an eval-stage intern::Interner to preserve interned pointer identity across the MIR → eval boundary. Test harnesses and orchestrator utilities are updated to construct typed Value inputs directly (without the JSON decoder/type-env dependency) and to pass the appropriate context/interner types through the compilation/execution stages.

Changes:

Split evaluation context into generation/execution contexts and updated Postgres compilation + orchestrator execution call sites accordingly.
Added eval-stage intern::Interner (convertible from MIR interner) and migrated decoder/tests to use it.
Reworked orchestrator test input construction to build heap-allocated typed Value trees directly; graph API compile_query was stubbed pending BE-537.
