Basic SRML Module Api #199

Closed Latrasis closed 5 years ago

Latrasis commented 5 years ago

Based on #198, we need to setup an srml runtime api including:

[ ] cap9_proc_call(proc_id: &str, input: &[u8], result: &mut [u8]) -> Result<Vec,Error>
[ ] cap9_proc_reg(proc_id: &str, addr: Option<Address>, cap_list: CapList) -> Result<(), Error>
[ ] cap9_proc_set_entry(proc_id: &str) -> Result<(), Error>
[ ] Similar to create - cap9_kernel_init(amount:U256, entry_code: &[u8]).

A placeholder clist is now being stored in AccountDb successfully. Next step is to make that into a useful data structure.

JakeOShannessy commented 5 years ago

I'm currently using an array of 7 booleans to represent the capabilities. As this data structure is not a critical part of the design I suggest we leave it as that for now while we focus on other things.

Something like DELEGATECALL from Ethereum has been implemented which should take us toward completing this issue. Two important notes:

It works, but there is plenty of complexity that I haven't fully considered and made sure that it's actually doing the right thing. I've simply made sure that storage does what we expect.
This function will need more functionality to make it do what we want (handle caps etc.).

Closing this for now, considering we're dealing with an api that might not fit with what we expect.
