feat: VVM injection, internal functions and variables #294

Open DanielSchiavini opened 2 months ago

DanielSchiavini commented 2 months ago

What I did

Add support for inject_function, internal and _storage contract methods for any contract compiled via the VVM
The performance is probably not great, since many recompiles are currently used
However, this might be still useful for users that want to upgrade boa and keep 0.3 vyper code around

How I did it

The methods recompile a version of the contract with a new internal method
When the method is called, it will temporarily change the bytecode at the destination
This is of course not very performant, but may be improved later
