From e727362998466ed3bbf0a7c5382b39bb3ad02e13 Mon Sep 17 00:00:00 2001 From: LucienSong Date: Tue, 21 Apr 2026 04:44:29 +0800 Subject: [PATCH 1/8] review: P1-P4/P7 safety & efficiency fixes P1 - Architecture (background agent): - Split node/node.rs (4575 lines) into node/ module: mod.rs, event_loop.rs, block_producer.rs, block_importer.rs, p2p_handlers.rs, dev_rpc.rs - Split rpc/handler.rs (4762 lines) into handler/ module: mod.rs, eth.rs, evm.rs, shell_api.rs, net.rs, debug.rs, admin.rs - Fix production unwrap() in cli/commands/run.rs and historical_sync.rs P2 - Core types: with direct &buf[1..] slice (buf.is_empty() already checked above) P4 - Consensus safety: - Add HashSet
slashed field to PoaConfig - Modify is_authority() to exclude slashed addresses - Add slash_authority() to PoaConfig and PoaEngine - Wire equivocation slashing in event_loop.rs: replace TODO log-only with consensus.write().slash_authority(&equivocation.offender) P7 - Network efficiency: - Add send_to_peer() to NetworkService trait with default broadcast fallback - Fix BodyResponse amplification: change broadcast() to send_to_peer(&peer) preventing O(n) data amplification to all connected peers - Fix Libp2pNetwork::broadcast() missing BodyRequest/BodyResponse match arms (compile error when libp2p feature enabled) P9 - Memory safety: - Change tx_broadcast from unbounded_channel to channel(4096) - Use try_send (non-blocking) in RPC handler to avoid blocking on full channel - Update RPC server and handler types: UnboundedSender -> Sender Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- crates/cli/src/commands/run.rs | 11 +- crates/consensus/src/poa.rs | 23 +- crates/core/src/account.rs | 5 +- crates/network/src/libp2p_service.rs | 2 + crates/network/src/service.rs | 14 +- crates/node/src/historical_sync.rs | 6 +- crates/node/src/node/block_importer.rs | 463 +++++ crates/node/src/node/block_producer.rs | 236 +++ crates/node/src/node/dev_rpc.rs | 57 + crates/node/src/node/event_loop.rs | 809 ++++++++ crates/node/src/{node.rs => node/mod.rs} | 1731 +---------------- crates/node/src/node/p2p_handlers.rs | 137 ++ crates/rpc/src/handler/admin.rs | 67 + crates/rpc/src/handler/debug.rs | 43 + crates/rpc/src/handler/eth.rs | 802 ++++++++ crates/rpc/src/handler/evm.rs | 51 + crates/rpc/src/{handler.rs => handler/mod.rs} | 1584 +-------------- crates/rpc/src/handler/net.rs | 144 ++ crates/rpc/src/handler/shell_api.rs | 403 ++++ crates/rpc/src/server.rs | 2 +- 20 files changed, 3337 insertions(+), 3253 deletions(-) create mode 100644 crates/node/src/node/block_importer.rs create mode 100644 crates/node/src/node/block_producer.rs create mode 100644 crates/node/src/node/dev_rpc.rs create mode 100644 crates/node/src/node/event_loop.rs rename crates/node/src/{node.rs => node/mod.rs} (56%) create mode 100644 crates/node/src/node/p2p_handlers.rs create mode 100644 crates/rpc/src/handler/admin.rs create mode 100644 crates/rpc/src/handler/debug.rs create mode 100644 crates/rpc/src/handler/eth.rs create mode 100644 crates/rpc/src/handler/evm.rs rename crates/rpc/src/{handler.rs => handler/mod.rs} (67%) create mode 100644 crates/rpc/src/handler/net.rs create mode 100644 crates/rpc/src/handler/shell_api.rs diff --git a/crates/cli/src/commands/run.rs b/crates/cli/src/commands/run.rs index 366c085a..39a9e66f 100644 --- a/crates/cli/src/commands/run.rs +++ b/crates/cli/src/commands/run.rs @@ -652,11 +652,12 @@ async fn run_with_store( } else { eprintln!(" Pruning: archive (keep all)"); } - if args.body_retention.is_some_and(|v| v > 0) { - eprintln!( - " Bodies: keep last {} blocks", - args.body_retention.unwrap() - ); + if let Some(retention) = args.body_retention { + if retention > 0 { + eprintln!(" Bodies: keep last {} blocks", retention); + } else { + eprintln!(" Bodies: archive (keep all)"); + } } else { eprintln!(" Bodies: archive (keep all)"); } diff --git a/crates/consensus/src/poa.rs b/crates/consensus/src/poa.rs index 4580f611..9713fd0a 100644 --- a/crates/consensus/src/poa.rs +++ b/crates/consensus/src/poa.rs @@ -20,6 +20,9 @@ pub struct PoaConfig { pub max_future_secs: u64, /// Number of blocks per epoch. 0 means no epochs (legacy behavior). pub epoch_length: u64, + /// Authorities that have been slashed for equivocation and are excluded from + /// block production.
