1207 :
1208 : For reference this is the general code path which contains all relevant
1209 : pre-transactions checks in the v2.0.x Agave client from upstream
1210 : to downstream is as follows:
1211 :
1212 : confirm_slot_entries() which calls verify_ticks() and
1213 : verify_transaction(). verify_transaction() calls verify_and_hash_message()
1214 : and verify_precompiles() which parallels fd_executor_txn_verify() and
1215 : fd_executor_verify_transaction().
1216 :
1217 : process_entries() contains a duplicate account check which is part of
1218 : agave account lock acquiring. This is checked inline in
1219 : fd_runtime_pre_execute_check().
1220 :
1221 : load_and_execute_transactions() contains the function check_transactions().
1222 : This contains check_age() and check_status_cache() which is paralleled by
1223 : fd_executor_check_transaction_age_and_compute_budget_limits() and
1224 : fd_executor_check_status_cache() respectively.
1225 :
1226 : load_and_execute_sanitized_transactions() contains validate_fees()
1227 : which is responsible for executing the compute budget instructions,
1228 : validating the fee payer and collecting the fee. This is mirrored in
1229 : firedancer with fd_executor_compute_budget_program_execute_instructions()
1230 : and fd_executor_collect_fees(). load_and_execute_sanitized_transactions()
1231 : also checks the total data size of the accounts in load_accounts() and
1232 : validates the program accounts in load_transaction_accounts(). This
1233 : is paralled by fd_executor_load_transaction_accounts(). */
