From 59ecd1972331ba9f7dd3806c5fe26acb4d405bdf Mon Sep 17 00:00:00 2001 From: crazywriter1 Date: Thu, 14 May 2026 23:55:08 +0300 Subject: [PATCH] feat: bubble inner revert in NativeTransferHelper and implement mesh.rs check NativeTransferHelper.relay now propagates inner call revert data via inline assembly when requireSuccess is true, so blocklist errors like ERR_BLOCKED_ADDRESS surface in tests instead of a generic "Relay reverted". NativeFiatToken.test.ts updated to assert ERR_BLOCKED_ADDRESS for the blocked-address inner frame case (resolves the FIXME). crates/test/checks/src/mesh.rs replaces the todo!() placeholder with a net_peerCount-based peer count check (gossipsub mesh isn't exposed; this is the closest available proxy for healthcheck purposes). --- contracts/src/mocks/NativeTransferHelper.sol | 9 +- crates/test/checks/src/mesh.rs | 149 ++++++++++++++++++- tests/localdev/NativeFiatToken.test.ts | 3 +- 3 files changed, 150 insertions(+), 11 deletions(-) diff --git a/contracts/src/mocks/NativeTransferHelper.sol b/contracts/src/mocks/NativeTransferHelper.sol index f726b18..b66a11a 100644 --- a/contracts/src/mocks/NativeTransferHelper.sol +++ b/contracts/src/mocks/NativeTransferHelper.sol @@ -55,8 +55,13 @@ contract NativeTransferHelper { /// @notice Relays a call with value to the target, optionally requiring success function relay(address target, uint256 amount, bool requireSuccess, bytes calldata data) external payable { - (bool success,) = target.call{value: amount}(data); - require(success || !requireSuccess, "Relay reverted"); + (bool success, bytes memory returndata) = target.call{value: amount}(data); + if (!success && requireSuccess) { + assembly ("memory-safe") { + let len := mload(returndata) + revert(add(returndata, 0x20), len) + } + } } /// @notice Self-destructs the contract, sending any remaining balance to the target address diff --git a/crates/test/checks/src/mesh.rs b/crates/test/checks/src/mesh.rs index 275b080..364afe8 100644 --- a/crates/test/checks/src/mesh.rs +++ b/crates/test/checks/src/mesh.rs @@ -14,20 +14,155 @@ // See the License for the specific language governing permissions and // limitations under the License. +//!
