A runtime panic was triggered in promoteExecutables/demoteUnexecutables when account balance was converted with uint256.MustFromBig(...): panic: overflow ... legacypool.go:1637 Root cause: - pool.currentState.GetBalance(addr) can exceed uint256 range in this code path. - uint256.MustFromBig(balance) panics on overflow, crashing the reorg loop. What this commit changes: - remove uint256.MustFromBig(balance) from executable/non-executable filtering paths - change list.Filter costLimit from *uint256.Int to *big.Int, and compare costs using big.Int directly - keep overflow-safe totalcost accounting for replacements (subtract old cost first, then add new) - return txpool.ErrSpecialTxCostOverflow for special-tx cost/totalcost overflow instead of returning (false, nil) - avoid partial pending-state mutation by attaching a new pending list only after overflow-safe totalcost calculation succeeds Tests: - add regression coverage for special-tx overflow rejection returning non-nil error - verify no pending/lookup/nonce mutation on overflow rejection - cover replacement paths to ensure no intermediate-overflow regressions in list.Add/promoteSpecialTx |
