feat(cheatcodes): base implementation of cheatcode system #58

tchataigner · 2023-04-18T18:27:09Z

Description

This PR introduces cheatcodes in Kythera. The inspiration for what the system allows is heavily inspired from Foundry's cheatcodes.

Changelog

Major

We now implement most of the components from the ref-fvm repo as we need to have granular control over them for the cheatcode system to work. This implementation is heavily inspired from the conformance test framework from @Stebalian on the ref-fvm
- KytheraMachine: Stores override values.
- KytheraCallManager: Set override values when detects a send() syscall to actor Id 98 (cheatcodes actor).
- KytheraKernel: Actually override values at call time.
Introducing an OverrideContext structure that allows us to store at the KytheraMachine level different value to alter information when cheatcodes are invoked.
Deploying a Cheatcode Actor at Actor Id 98. It contains entrypoints corresponding to the different cheatcodes we want to be available to our users.
Updated the way we compile actors to get binaries. Now, all actors can be found under <project-root>/actors. In this folder we find both actors (available at all time) and test-actors (only available if feature=["testing"] is enabled). This allows to have some binaries built and used in our kythera-lib without actually building everything everytime.

Minor

Actor are no longer deployed at a random ID. Instead, we first create an address from their new and register it on-chain.
Set default Kythera chain Id to 1312

Closes #22

Change checklist

I have performed a self-review of my own code
I have made corresponding changes to the documentation
I have added tests that prove my fix is effective or that my feature works

* Upgrade builtins dependencies to revision for release 10.0 (M2.1 of FVM)

* Using code_by_id() method to retrieve builtins code CID from Manifest * Get builtins actor ID from builtin crate

from the rest of the methods.

* Removed dependencies to builtin actors to rely on Chainsafe repo instead as per filecoin-project/builtin-actors#194 (comment)

* Setup all necessary builtins in our local development environment

* Adding actor to test builtins deployment in Kythera

* Adding actor to test constructor and setup being called in test flow

* Updating the builtin test actor to test that all builtins code are deployed at their address * Fix clippy

- introduce constructor_setup_test_actor crate to test Setup and Constructor functions

…ra into feature/builtins-genesis

…e-constructor-setup

* Needed to have a Cheatcodes actor incorporated in our library so re-used the kythera_test_actors crate logic to generate it. kythera_test_actors have been renamed to kythera_actors. * Created a testing feature for kythera_actors to only build test_actors when we need them (mostly during tests of our kythera_lib).

Thanks for this Thomas, first Round of review, I still need to read the actors and the handle_cheatcode function

This file needs all these overrides mainly because of this right? I.e to be able to abstract the CallManager, can we make a comment stating that with a TODO to fix this upstream?

This is one of the reasons along with overriding of context in msg_context() and network_context(). So I'm not 100% sure that changing the upstream to remove the passing of the call manager will actually have an impact on our need to do what's currently being implemented (as we are actually overriding the logic of some methods).

What's your take on that ?

nit: OnceCell is going to be stable soon so it probably makes sense to use its crate instead

wdyt of actually calculating them and hardcoding them? We can then have tests for them on this module to assert that they correspond to the strings and then we could match on them with u64's on handle_cheatcode

are the builtin actors test actors?

No ! Good one, must have been a wrong update on my side. Thanks for that 🙏

this should still have a comment no?
