Auto-import scanning now respects package exports (
47ca648)
A new experimental preference, js/ts.preferences.autoImportEntrypointDirectorySearch, controls whether auto-import recursively scans packages without exports entries. The compiler and language service now track “deep import” packages separately so they can avoid expensive directory walks unless explicitly enabled, which should reduce false-positive auto-imports and improve performance in large dependency trees.
Files outside rootDir are now diagnosed earlier (
a697eb3)
TypeScript now checks that files matched by tsconfig.json include actually live under rootDir, instead of discovering the mismatch later during emit/output-path calculation. This tightens project validation and surfaces a clearer error when source files are outside the expected tree.
Enum auto-increment after NaN now errors correctly (
d686a16)
The checker now treats a NaN-producing enum initializer as a missing numeric value for subsequent members, matching TS 6.0 behavior. That fixes a case where enum members after 0 / 0 could silently inherit NaN instead of producing the expected initializer diagnostic.
Type-to-string stack overflows are cached away (
49f210f)
NodeBuilder serialization now reuses a single cached instance for potentially circular internal operations, with an extra guard around cached type expansion. This prevents a stack overflow in typeToString-style paths for self-referential types and makes circular type rendering more robust.
realpath and symlink-aware VFS matching are faster (
ff5823b)
The virtual filesystem now records which entries were originally symlinks/reparse points so callers can avoid re-checking them repeatedly. vfsmatch also avoids repeated realpath work, which should help globbing and directory traversal on symlink-heavy trees.
Document highlights no longer assert on merged namespaces (5b70f41)
A debug assertion in reference gathering was replaced with a safe skip for merged symbols, fixing a crash for export = inside a namespace merged with a class. This restores document highlights on that pattern and removes an invalid assumption about module-symbol shape.
Decorated static accessors stop crashing diagnostics (9f1f2da)
The accessor-decoration path now null-checks the second accessor before inspecting decorators, preventing a diagnostics crash on decorated classes with static getters. This is a targeted correctness fix for decorator-heavy code.
