[Rosetta] Track internal transactions (#3475) * [rosetta] Refactor operations & prep for internal tx exposure * Remove gas op relation for tx operations. Gas is for submission & processing the tx, thus not really related to the amount being transferred * Make optional starting op a ptr to a uint to keep consistent * Reorg file for consistency of fn placement * Rename functions for clarity * Make getContractCreationNativeOperations consume getBasicTransferOperations for consistency * Remove invariant doc as it does not apply anymore Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Add framework for parsing traced txs * Define ContractInfo struct for FormatTransaction * Add tx trace helper function defs & propagate type defs * Add a GetTransactionStatus helper fn for Operation formatting/creation * Add wrapper function, getContractTransferNativeOperations, to get internal operations Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Implement transaction tracer Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [tracer] Add CallerAddress & CodeAddress to tracer logs Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [tracer] Remove ptr to slice & map in StructLogRes Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Implement getContractInternalTransferNativeOperations * Add ContractAddress to ContractInfo for future usages (i.e: erc20 parsing) * Only check for contract address if there is tx data in BlockTransaction Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Fix status report for contract related txs Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [tracer] Expose contract address instead of code address Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Add trace cache & update TODO * Trace any PLAIN transaction instead of only transactions with data. This is to account for fall back contract fn calls & ignore staking data. Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Make internal tx formatter not return err on nil exec result Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * Fix lint Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Fix tests Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Add internal tx unit tests * Fix tx data len check for contract related transfers as a transaction with len 0 data can happen for a contract (and fail) due to fall back operations. Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Update invariant comment Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Expose mutually exclusive ops + update docs & tests Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu> * [rosetta] Fix docs and err msgs Signed-off-by: Daniel Van Der Maden <dvandermaden0@berkeley.edu>
