From 0e51ace1ea9891a1b447964a1aa1461fbca0f8d6 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Mon, 14 Sep 2026 22:58:51 +0000 Subject: [PATCH 1/2] fix: resolve cache/navigation binding and unsafe mutation parallelization Fixes #1810 - server-cache-with-object-literal: Use resolveImportedApiReference and collectBindingAliases to properly track React.cache wrappers through immutable bindings, check all argument positions for fresh objects/arrays, and report once per call. Shadowed and non-React cache functions stay silent. - nextjs-no-redirect-in-try-catch: Extend findGuardingTryStatement and catchClauseRethrowsCaught with optional framework rethrow predicates. Recognize unstable_rethrow(error) from next/navigation as equivalent to throw, including renamed imports and namespace access. Deferred, wrong-error, and shadowed rethrows still report. - server-sequential-independent-await and async-parallel: Use findSideEffect to detect mutating HTTP requests (POST, PUT, PATCH, DELETE) and preserve their ordering. Independent GET requests continue to report. Add 37 regression test cases covering binding resolution, multi-argument detection, unstable_rethrow patterns, and HTTP mutation ordering.
