The `fmt` code is retained via SDK-internal vtables, not our derives. + +Measurement integrity was verified with a canary: changing an exported +constant flips the build's MD5 and reverting restores the *exact* original +hash, so builds are deterministic and the toolchain demonstrably recompiled +between measurements. The nulls are real: at `opt-level="z"` with fat LTO and +`codegen-units=1`, LLVM already makes these inlining decisions optimally, and +annotations only add maintenance surface. The honest lever at the toolchain +level is `wasm-opt`, which is also what `stellar contract optimize` wraps. + +Remaining size, for future reference: after optimization the binary is ~53% +code, ~38% `contractspecv0`. The spec section embeds every exported doc +comment; trimming docs would shrink it but is a documentation-quality trade, +not a code-size optimization, and is deliberately not done here. diff --git a/scripts/deploy.sh b/scripts/deploy.sh index 0f732627..f5a6eb9f 100755 --- a/scripts/deploy.sh +++ b/scripts/deploy.sh @@ -45,7 +45,7 @@ esac # โ”€โ”€ Paths โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ WASM_PATH="target/wasm32v1-none/release/orbitchain_core.wasm" -OPTIMIZED_WASM_PATH="target/wasm32v1-none/release/orbitchain_core.wasm" +OPTIMIZED_WASM_PATH="target/wasm32v1-none/release/orbitchain_core.optimized.wasm" DEPLOYMENTS_DIR="deployments" DEPLOYMENT_FILE="${DEPLOYMENTS_DIR}/${NETWORK}.json" diff --git a/scripts/wasm_size_check.sh b/scripts/wasm_size_check.sh new file mode 100755 index 00000000..de4e1eb9 --- /dev/null +++ b/scripts/wasm_size_check.sh @@ -0,0 +1,55 @@ +#!/usr/bin/env bash +# Issue #117 โ€“ WASM size regression baseline. +# +# Compares each wasm-opt'd contract against a checked-in byte budget and fails +# if any exceeds it.
