Speed up short-lived checker caches by jakebailey · Pull Request #64871 · microsoft/TypeScript

Jake Bailey (jakebailey) · 2026-10-19T17:40:33Z

Every instantiation under an active mapper built and hashed a 128-bit key before probing the mapper's cache, even when the mapper had just been pushed and its cache was necessarily empty. Most keys carry no alias, so the type ID alone identifies the entry.

Active mapper caches and inference visited sets are also cleared far more often than they are filled. Clearing a Go map costs time proportional to its capacity, which stays at its high-water mark, so each pop of an active mapper and each reuse of an inference state paid for the largest cache seen so far. Both now use a small table keyed by the same 128-bit keys that clears in constant time by bumping a generation counter instead of touching every slot.

The measurements below are for the key hashing change alone; the per-commit measurements for the constant-time clears are in their commit messages.

The instantiation cache of an active mapper is cleared every time the mapper is popped. Clearing a Go map takes time proportional to its capacity, which stays large once a map has grown, so instantiating under a mapper whose cache once held many entries paid for that size on every pop. The caches are now small open-addressing tables whose entries record the generation they were written in; clearing starts a new generation. They also hash keys with a multiply rather than a full 128-bit hash.

Inference states are pooled, and each one's visited map is cleared when it is returned to the pool. Like the mapper caches, a pooled map that once grew large paid for its capacity on every clear, and every probe paid for hashing a struct key.
