Introduce CallTracker to assign sequential frame IDs and maintain call paths during opcode traversal. This enables accurate identification of which contract call each opcode belongs to, even when the same contract is called multiple times. Extend Structlog with CallFrameID and CallFramePath fields to persist the tracking information alongside each opcode record. Update extractCallAddress to handle all CALL-type opcodes (CALL, CALLCODE, DELEGATECALL, STATICCALL) for complete call target extraction.
feat: detect CREATE/CREATE2 opcodes and fetch contract address from receipt refactor: replace extractCallAddress with extractCallAddressWithCreate to handle contract creation addresses
… trace-based computation - Remove fetchCreateAddress and hasCreateOpcode helpers - Introduce ComputeCreateAddresses to extract addresses directly from trace - Update extractCallAddressWithCreate signature to accept index and map - Rename queue name from "transaction-structlog" to "transaction_structlog" - Expand test coverage for nested and failed CREATE scenarios
The root frame now starts at depth 1 instead of 0 to match the actual EVM structlog output, where execution begins at depth 1. All tests updated to reflect the new depth semantics.
…om child gas Introduce GasSelf to represent the gas consumed by an opcode *excluding* any gas spent in child frames. For CALL/CREATE opcodes this yields the pure call overhead (warm/cold access, memory expansion, value transfer); for all other opcodes GasSelf equals GasUsed. This allows accurate aggregation of total execution gas without double counting. - Add ComputeGasSelf() helper that subtracts the sum of *direct* child GasUsed values from each CALL/CREATE opcode’s GasUsed. - Extend Structlog struct and ClickHouse schema with new GasSelf column. - Update both ProcessTransaction() and ExtractStructlogs() to populate the new field. - Provide extensive unit tests covering nested, sibling and edge cases.
