Move more code into state-account #10840

dvdplm · 2019-07-04T14:05:05Z

Moves ethcore/state into a new account-state crate.

State management has a piece that is tightly coupled to other ethcore modules, mainly Machine and Excutive (and related types and support code).
In order to extract the state management code from ethcore I have left one module – executive_state – in ethcore that isolates the code where the state code is too entangled with the rest of ethcore to be tackled at this time. The tests for state management are also still in ethcore because of the tight coupling with other ethcore modules. While this is rather ungainly and unsatisfactory I think it's an improvement to have this code in an isolated unit that makes it obvious where the coupling takes place.

The end result is that we now have 6k loc less in ethcore and the following new crates:

trace
factories
account-state
pod
account-db from Extract AccountDB to account-db #10839

We also have a somewhat smaller API surface on ethcore.

The diff is very noisy and for that I apologise. The only really new code is in executive_state.rs and the rest is mostly cleanup and munging. None of the TODOs that show up as "green" are mine (but still worthy of consideration ofc). I have used this branch to sync Goerli.

Great PR! I have only a few questions about the code. I believe that those changes are very needed and are a huge step towards getting ethcore more modular

ethcore/factories/src/lib.rs

ethcore/src/error.rs

ethcore/trace/Cargo.toml

ethcore/trace/src/db.rs

* master: EIP-1702: Generalized Account Versioning Scheme (#10771)

Looks good, definitely a good step forward.

+ethcore-blockchain = { path = "../blockchain" }
+ethcore-db = { path = "../db" }
+ethereum-types = "0.6"
+evm = { path = "../evm" }


Again requiring entire EVM seems odd, would be worth to remove it in the future.

We use CallType from the evm, that's all. Seems like a good opportunity for a refactor indeed.

+common-types = { path = "../types"}
+ethcore-blockchain = { path = "../blockchain" }


Do we really need the entire blockchain or just some trait definitions?

Currently we use BlockChainDB and the contentious DatabaseExtras, e.g.:

pub struct TraceDB<T> where T: DatabaseExtras { /// cache traces: RwLock<HashMap<H256, FlatBlockTraces>>, /// hashes of cached traces cache_manager: RwLock<CacheManager<H256>>, /// db db: Arc<dyn BlockChainDB>, /// tracing enabled enabled: bool, /// extras extras: Arc<T>, }

What is your thinking here? Are you thinking we should move traits to a common-traits crate?

looks good. I think we should get it in asap and we can fix trace <-> blockchain relation later on

@tomusdrw @debris Merging this but I'll make sure the following gets addressed in follow up PRs:

sort out the trace <–> blockchain interdependencies
cf. Move more code into state-account #10840 (comment)
attempt to avoid pulling in EVM in trace and account-state
make the conditional "dump state" suck a bit less

* master: Move more code into state-account (#10840) Remove compiler warning (#10865) [ethash] use static_assertions crate (#10860)

* master: Run cargo fix on a few of the worst offenders (#10854) removed redundant fork choice abstraction (#10849) Extract state-db from ethcore (#10858) Fix fork choice (#10837) Move more code into state-account (#10840) Remove compiler warning (#10865) [ethash] use static_assertions crate (#10860)
