26.5.0-RC1: Bound precompile result caches to semantic-prefix slice (#10350)
@jflo jflo tagged this 28 Apr 19:54 
* Bound precompile result caches to semantic-prefix slice

Each precompile already knows the fixed semantic input length its
implementation reads. Key the cache and store the cached input on
that prefix so bytes past the semantic length no longer distinguish
entries. Add a byte-weight cap (16 MB per cache, with Integer.BYTES
floor per entry) across all 14 caches for a uniform memory ceiling.

Also wire --cache-precompiles into evmtool state-test and block-test
sub-commands so reference-test runs can exercise the cache code path.

* Centralize precompile cache builder; add BLS12 cache test

Address PR review feedback:

- Add `AbstractPrecompiledContract.resultCacheBuilder()` so the 14
  cache definitions share one Caffeine config (cap and weigher).
  Pairing/multi-exp callers chain `.expireAfterWrite(...)` on top.
- KZG, P256 and BLAKE2 now pass their fixed spec lengths (192, 160,
  213) to `getCacheKey` instead of `input.size()`, documenting intent
  even though prior validation makes the two equivalent today.
- `PrecompileCachePrefixBoundTest` adds a BLS12_G1ADD tail-padded
  cache-hit test exercising the abstract BLS12 cache path, and XORs a
  per-run nonce into each canonical input so the static caches no
  longer cause order-dependent results across test invocations.
