From 9c85075682042fae3aa7beae4c59a1c8f1270c6a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jerem=C3=ADas=20Salom=C3=B3n?= <48994069+JereSalo@users.noreply.github.com> Date: Thu, 31 Oct 2024 14:50:53 -0300 Subject: [PATCH] feat(levm): implement `Cache` and refactor `Db` (#991) **Motivation** We currently have an in-memory database that should soon be replaced by the node's in-disk database. For that purpose we want to allow us to switch between both kinds of databases. The need to implement this PR's features and refactor the `Db` arose while working on #904. **Description** This PR includes: - Adding a `Cache` to store warm accounts. This removes the need of having `accessed_accounts` and `accessed_storage_slots` sets in `Substate` because we know that if they are cached then they are warm. - Making our `Db` implement the `Database` trait and interact with it only using methods and not it's attributes, so in the future we can implement that trait for the actual node's database. - Fix call opcodes and remove delegate attribute from `CallFrame`. Part of #814. --------- Co-authored-by: Juani Medone Co-authored-by: maximopalopoli Co-authored-by: Javier Chatruc --- crates/vm/levm/Cargo.toml | 4 - crates/vm/levm/docs/substate.md | 3 + crates/vm/levm/src/call_frame.rs | 9 +- crates/vm/levm/src/constants.rs | 1 - crates/vm/levm/src/db.rs | 126 ++ crates/vm/levm/src/lib.rs | 1 + crates/vm/levm/src/opcode_handlers/block.rs | 16 +- .../levm/src/opcode_handlers/environment.rs | 93 +- .../stack_memory_storage_flow.rs | 54 +- crates/vm/levm/src/opcode_handlers/system.rs | 43 +- crates/vm/levm/src/utils.rs | 89 +- crates/vm/levm/src/vm.rs | 667 +++++----- crates/vm/levm/tests/tests.rs | 1131 +++++++++-------- 13 files changed, 1239 insertions(+), 998 deletions(-) create mode 100644 crates/vm/levm/docs/substate.md create mode 100644 crates/vm/levm/src/db.rs diff --git a/crates/vm/levm/Cargo.toml b/crates/vm/levm/Cargo.toml index d41d028e43..cd09d7d50c 100644 --- a/crates/vm/levm/Cargo.toml +++ b/crates/vm/levm/Cargo.toml @@ -19,7 +19,3 @@ hex = "0.4.3" [features] ethereum_foundation_tests = [] - -[profile.test] -opt-level = 3 -debug-assertions = true diff --git a/crates/vm/levm/docs/substate.md b/crates/vm/levm/docs/substate.md new file mode 100644 index 0000000000..806511ed2f --- /dev/null +++ b/crates/vm/levm/docs/substate.md @@ -0,0 +1,3 @@ +## Substate + +`accessed_addresses` and `accessed_storage_keys` follow the structure defined in [EIP 2929](https://eips.ethereum.org/EIPS/eip-2929#specification) diff --git a/crates/vm/levm/src/call_frame.rs b/crates/vm/levm/src/call_frame.rs index 80e3082298..2d94b63b15 100644 --- a/crates/vm/levm/src/call_frame.rs +++ b/crates/vm/levm/src/call_frame.rs @@ -62,10 +62,13 @@ pub struct CallFrame { pub gas_limit: U256, pub gas_used: U256, pub pc: usize, - pub msg_sender: Address, // Origin address? + /// Address of the account that sent the message + pub msg_sender: Address, + /// Address of the recipient of the message pub to: Address, + /// Address of the code to execute.
