5 Nov 2024 12:12:44 -0300 Subject: [PATCH 058/113] feat(levm): prepare levm-ethereum-rust-integration for merge (#1064) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Motivation** Eventually, we want to stop using revm and replace it with levm. The integration is a work in progress in this PR https://github.com/lambdaclass/lambda_ethereum_rust/pull/1029. This PR aims to be the first step. It aims to prepare the current codebase so that both implementations can coexist while levm continues to be developed and does not disturb the rest of the development. When the time to remove revm comes, it'd be easier with this proposal since it'd require removing the code under the #[cfg(not(feature = "levm"))] and after that, to remove the feature flag definitively. **Description** - Adds the `levm` feature flag to the `vm` and `blockchain` packages, and to the `ethereum_rust` binary. - In `vm`, add `execute_block` implementation that uses `levm` and use it when `levm` feature flag is set. Use the original implementation if not. - In `blockchain`, add `add_block` implementation that uses `levm` and use it when `levm` feature flag is set. Use the original implementation if not. --------- Co-authored-by: Jeremรญas Salomรณn <48994069+JereSalo@users.noreply.github.com> Co-authored-by: JereSalo --- cmd/ethereum_rust/Cargo.toml | 1 + crates/blockchain/Cargo.toml | 2 + crates/blockchain/blockchain.rs | 45 +++ crates/vm/Cargo.toml | 1 + .../levm/src/opcode_handlers/environment.rs | 20 +- .../stack_memory_storage_flow.rs | 16 +- crates/vm/levm/src/vm.rs | 4 +- crates/vm/levm/tests/tests.rs | 57 +++- crates/vm/vm.rs | 275 ++++++++++-------- 9 files changed, 286 insertions(+), 135 deletions(-) diff --git a/cmd/ethereum_rust/Cargo.toml b/cmd/ethereum_rust/Cargo.toml index cd14bad00..69c87285e 100644 --- a/cmd/ethereum_rust/Cargo.toml +++ b/cmd/ethereum_rust/Cargo.toml @@ -41,3 +41,4 @@ path = "./ethereum_rust.rs" default = [] dev = ["dep:ethereum_rust-dev"] l2 = ["ethereum_rust-vm/l2"] +levm = ["ethereum_rust-vm/levm", "ethereum_rust-blockchain/levm"] diff --git a/crates/blockchain/Cargo.toml b/crates/blockchain/Cargo.toml index b29841065..9f60588d8 100644 --- a/crates/blockchain/Cargo.toml +++ b/crates/blockchain/Cargo.toml @@ -10,6 +10,7 @@ thiserror.workspace = true sha3.workspace = true tracing.workspace = true bytes.workspace = true +cfg-if = "1.0.0" ethereum_rust-rlp.workspace = true ethereum_rust-core = { path = "../common", default-features = false } @@ -29,3 +30,4 @@ libmdbx = [ "ethereum_rust-storage/default", "ethereum_rust-vm/libmdbx", ] +levm = ["ethereum_rust-vm/levm"] diff --git a/crates/blockchain/blockchain.rs b/crates/blockchain/blockchain.rs index 4825dc929..f51518633 100644 --- a/crates/blockchain/blockchain.rs +++ b/crates/blockchain/blockchain.rs @@ -25,6 +25,51 @@ use ethereum_rust_vm::{evm_state, execute_block, spec_id, EvmState, SpecId}; /// canonical chain/head.

The EVM doesn't have a "max" memory size, this max is limited by the gas avaiable. Opcodes that didn't have gas implemented were a problem so I partially implemented gas costs for them, just for their memory expansion cost. - Trying to add with overflow - For this error normal addition was replaced for `checked_add` and returned an error if it overflowed.
