fix(noMisusedPromises): perf regression by ematipico · Pull Request #11314 · biomejs/biome

ematipico · 2026-08-12T11:02:47Z

Summary

Took an hour to analyse this via agent lol 🤣

The bug was caused by the use of a non-tracked query, which means queries coming from different expressions were always recomputed.

Also, deep import paths always queried uncached results.

Now bottom-up queries are tracked, so queries that ask for the same information are cached.

Test Plan

Added new benchmarks. Will trigger a preview release 🤞

I also added some stress tests. I asked the agent to take inspiration from how Ruff does it.

I also ran the same stress tests prior to the fix, to make sure things work.

The pre-fix run is conclusively red: after warming one root, the remaining 63 roots executed infer_binding_type_with_import_budget 8,064 times (63 × 128). The fixed branch executes it 0 times for the same roots, so this is a deterministic structural regression test rather than a timing assertion.

Walkthrough

This change reduces repeated work during imported type inference. On-demand resolution tracks only the remaining import budget. Budgeted lookups use interned inputs. Import-depth preparation becomes reusable and bounded. Call inference skips the requested callback expression but retains spread resolution. Tests cover caching, invalidation, deep import chains, and call-argument inference. Benchmarks cover local, imported, callback, array, conditional, and spread promise scenarios.

Merge Risk: ⚪ Minimal · up to 2e502

This change improves promise-analysis performance through query caching and adds regression coverage; no actionable merge-blocking risk remains after normal checks and review.

signature does invalidate them. Assert events for infer_call_argument_type and

Document the import-budget contract.

The new rustdoc links to the query but does not define remaining. State that remaining is the number of on-demand import-resolution steps before bounded fallback. State that it is part of the interned key because the result can change with the remaining budget.

As per coding guidelines, Rust documentation must explain current behaviour, contracts, invariants, panics, module purpose, terminology, or rationale.
