GetRulesExtra derived a Rules' Lux rules from a process-wide last context: the chain config and timestamp of whichever Rules any goroutine evaluated most recently. Rules are evaluated concurrently, by block processing, the miner, the tx pool and every eth_call, so a Rules could read another evaluation's upgrades: its IsDurango, its predicaters, its enabled precompiles, and the intrinsic gas that depends on them. The context now travels with the Rules value. core's rules hook already put the chain config and timestamp in Rules.Payload for its precompile overrider; the overrider answers them, and GetRulesExtra reads them from the Rules it is given. RulesAt attaches them where no hook did. The global and SetRulesContext are gone. Every call site evaluates its Rules for the block it reads them for, so a caller that no other goroutine races sees the same rules as before. The blob pool's state checks passed a zero Rules and read the head's context the check before them had left; they now pass the head's Rules. TestRulesExtraIsTheRulesOwn evaluates two rule sets and reads the first; TestRulesExtraUnderConcurrentEvaluation reads four rule sets on four goroutines at once, across two times and two chains, including the intrinsic gas of a creation. TestActivePrecompiles, skipped for this bug, runs again. Co-authored-by: Hanzo Dev <[email protected]>
