Refactor RPC to make it more extensible #132

Closed DanielSchiavini closed 7 months ago

DanielSchiavini commented 7 months ago

What I did

Changed the NetworkEnv and CachingRPC so they are not dependent on the RPC URL. This makes it possible to implement a BrowserRPC in #124.

How I did it

Added new utility function boa.set_network_env(url)
Changed the environment so it has two ways of forking: via an URL or via the RPC
Changed CachingRPC to support either EthereumRPC or BrowserRPC via an unique identifier
Deprecated NetworkEnv(url) constructor - Using it with an URL generates a warning

How to verify it

boa.set_network_env(url) should work as previously
boa.env.fork(url) should work as previously
boa.env_fork_rpc(EthereumRPC(url)) should do the same as boa.env.fork(url)
NetworkEnv(url) should work as previously, however it will generate a deprecation warning

Description for the changelog

Deprecated NetworkEnv(url) constructor - Using it with an URL generates a warning.
