- Introduced `vm.Config` to multiple functions for customizable VM tracing. - Added tracer configuration flags (`vmtrace` and `vmtrace.jsonconfig`) to streamline monitoring during blockchain synchronization. - Updated GenesisContract and spanner interfaces for trace integration. - Integrated tracing hooks for StateSyncTx events.
Remove the 4 [DEBUG] log lines that were added during development to diagnose StateSyncTx tracing issues.
When Finalize is called, the chain parameter can be a *core.HeaderChain (not just *core.BlockChain). Without this change, the tracer in vmCfg is nil during finalization, so StateSyncTx tracing hooks never fire. - Add vmConfig field and GetVMConfig() method to HeaderChain - Set hc.vmConfig in NewBlockChain after creating the HeaderChain - Add else-if branch in Finalize and FinalizeAndAssemble to extract VM config from HeaderChain
The Process function creates a tracingStateDB wrapper for tracing but was passing the unwrapped statedb to Finalize, causing the tracer to miss StateSyncTx state changes.
