JoranHonig a9671de8a3 Balance modelling and symbolic sender variables (#1025) ... * add actor address to symbolic This will allow us to simulate semi-symbolic transaction senders * add value transfer to transaction global state creation * add proper balance tracking to world state and account * use address value vs string * disable actor address variable * use address directly * allow balance functions with int types * use value as getters since bitvecs aren't hashable * implement correct value transfer for suicide * use actor from actor pool * allow use of Or with *arg pattern * use bitvec instead of strings * add dynamic balance implementation to state datamodels * cleanup svm interface * use balance lambda in suicide op implementation * use bitvec instead of string address * update world state and account creation in symbolic * update tests to include overflow results * apply style rules * ignore previous open states for now * update native test to conform to new laser interface * fix incorrect types in the symbolic virtual machine * allow multiple types as input for address in account * fix type hint in symbolic.py * get int out of string in call * fix type in call op implementation * adapt test_transaction to conform to new laser interface * use static address to keep contracts from trying to enter themselves and make address type more dynamic * update evm test to conform to new laser interface * implement suicide to uncreated account * apply style rules * dynamically create colormap This removes the need for a globally maintained accountlist * get value out of address * add accounts getter * change symbolic test call to be valid with respect to the world state and account apis * remove dependency on globally recorded accounts * fix typing issues * fix type annotations in symbolic.py * fix remaining mypy warnings * simplify assertion check * execute lambda to get balance * make variable name plural * add documentation to svm constructor * use list comprehension to make code cleaner * remove comment * change variable name to plural * remove commented code * change variable name to conform to changed interface		6 years ago
