1430 :
1431 : For reference this is the general code path which contains all relevant
1432 : pre-transactions checks in the v2.0.x Agave client from upstream
1433 : to downstream is as follows:
1434 :
1435 : confirm_slot_entries() which calls verify_ticks() and
1436 : verify_transaction(). verify_transaction() calls verify_and_hash_message()
1437 : and verify_precompiles() which parallels fd_executor_txn_verify() and
1438 : fd_executor_verify_transaction().
1439 :
1440 : process_entries() contains a duplicate account check which is part of
1441 : agave account lock acquiring. This is checked inline in
1442 : fd_runtime_pre_execute_check().
1443 :
1444 : load_and_execute_transactions() contains the function check_transactions().
1445 : This contains check_age() and check_status_cache() which is paralleled by
1446 : fd_executor_check_transaction_age_and_compute_budget_limits() and
1447 : fd_executor_check_status_cache() respectively.
1448 :
1449 : load_and_execute_sanitized_transactions() contains validate_fees()
1450 : which is responsible for executing the compute budget instructions,
1451 : validating the fee payer and collecting the fee. This is mirrored in
1452 : firedancer with fd_executor_compute_budget_program_execute_instructions()
1453 : and fd_executor_collect_fees(). load_and_execute_sanitized_transactions()
1454 : also checks the total data size of the accounts in load_accounts() and
1455 : validates the program accounts in load_transaction_accounts(). This
1456 : is paralled by fd_executor_load_transaction_accounts(). */
