This reduces peer_handler.rs from 2,060 to 670 lines (~68% reduction), leaving it focused on ETH protocol methods (block headers/bodies). Added SnapClientError variant to SyncError for proper error handling. Updated plan_snap_sync.md to mark Phase 4 as complete. --- crates/networking/p2p/peer_handler.rs | 1414 +--------------------- crates/networking/p2p/snap/client.rs | 1439 +++++++++++++++++++++++ crates/networking/p2p/snap/mod.rs | 11 +- crates/networking/p2p/sync.rs | 5 +- crates/networking/p2p/sync/snap_sync.rs | 9 +- plan_snap_sync.md | 15 +- 6 files changed, 1480 insertions(+), 1413 deletions(-) create mode 100644 crates/networking/p2p/snap/client.rs diff --git a/crates/networking/p2p/peer_handler.rs b/crates/networking/p2p/peer_handler.rs index 48f6961cc8e..1dbf314c6d9 100644 --- a/crates/networking/p2p/peer_handler.rs +++ b/crates/networking/p2p/peer_handler.rs @@ -11,32 +11,15 @@ use crate::{ }, message::Message as RLPxMessage, p2p::{Capability, SUPPORTED_ETH_CAPABILITIES}, - snap::{ - AccountRange, AccountRangeUnit, ByteCodes, GetAccountRange, GetByteCodes, - GetStorageRanges, GetTrieNodes, StorageRanges, TrieNodes, - }, - }, - snap::encodable_to_proof, - sync::{AccountStorageRoots, SnapBlockSyncState, block_is_stale, update_pivot}, - utils::{ - AccountsWithStorage, dump_accounts_to_file, dump_storages_to_file, - get_account_state_snapshot_file, get_account_storages_snapshot_file, }, };

This caused unnecessary delays since state download is independent of header download and the pivot selection only needs recent headers. This change moves header downloading to a background task that runs in parallel with state download: - Add header_receiver and download_complete fields to SnapBlockSyncState - Create download_headers_background() function that runs header download in a separate tokio task and sends headers through an mpsc channel - Modify sync_cycle_snap() to spawn the background task and start state download immediately - Add process_pending_headers() helper to incrementally process headers at strategic points during snap_sync() - snap_sync() waits for initial headers only when needed for pivot selection This allows state download to begin much sooner, potentially reducing overall sync time significantly for mainnet syncs. --- crates/networking/p2p/sync/snap_sync.rs | 283 ++++++++++++++++++------ 1 file changed, 217 insertions(+), 66 deletions(-) diff --git a/crates/networking/p2p/sync/snap_sync.rs b/crates/networking/p2p/sync/snap_sync.rs index fc54ce89fd5..2a246d30db8 100644 --- a/crates/networking/p2p/sync/snap_sync.rs +++ b/crates/networking/p2p/sync/snap_sync.rs @@ -7,8 +7,8 @@ use std::collections::{BTreeSet, HashMap, HashSet}; use std::path::Path; #[cfg(feature = "rocksdb")] use std::path::PathBuf; -use std::sync::atomic::Ordering; use std::sync::Arc; +use std::sync::atomic::{AtomicBool, Ordering}; use std::time::{Duration, SystemTime}; use ethrex_blockchain::Blockchain; @@ -46,10 +46,13 @@ use ethrex_common::U256; use ethrex_rlp::encode::RLPEncode; /// Persisted State during the Block Sync phase for SnapSync -#[derive(Clone)] pub struct SnapBlockSyncState { pub block_hashes: Vec, store: Store, + /// Channel to receive headers from background download task + header_receiver: Option>>, + /// Flag indicating whether background header download is complete + download_complete: Option>, } impl SnapBlockSyncState { @@ -57,9 +60,38 @@ impl SnapBlockSyncState { Self { block_hashes: Vec::new(), store, + header_receiver: None, + download_complete: None, } } + /// Sets up the channel for receiving headers from the background download task + pub fn set_header_channel( + &mut self, + receiver: tokio::sync::mpsc::Receiver>, + download_complete: Arc, + ) { + self.header_receiver = Some(receiver); + self.download_complete = Some(download_complete); + } + + /// Non-blocking method to receive incoming headers from the background task + pub fn try_receive_headers(&mut self) -> Option> { + if let Some(receiver) = &mut self.header_receiver { + receiver.try_recv().ok() + } else { + None + } + } + + /// Check if the background header download is complete + pub fn is_download_complete(&self) -> bool { + self.download_complete + .as_ref() + .map(|flag| flag.load(Ordering::Acquire)) + .unwrap_or(true) + } + /// Obtain the current head from where to start or resume block sync pub async fn get_current_head(&self) -> Result { if let Some(head) = self.store.get_header_download_checkpoint().await?

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The sync completion logs already contain per-phase completion markers (e.g. "✓ BLOCK HEADERS complete: 25,693,009 headers in 0:29:00") but this data was not surfaced in the Slack messages or run summaries. This adds a parse_phase_timings() function that reads saved container logs and extracts timing, count, and duration for all 8 snap sync phases: Block Headers, Account Ranges, Account Insertion, Storage Ranges, Storage Insertion, State Healing, Storage Healing, and Bytecodes. The breakdown is appended to both the Slack notification (as a code block per network instance) and the text-based run log (run_history.log and per-run summary.txt).

charset=UTF-8 Content-Transfer-Encoding: 8bit After snap sync completes, the node switches to full sync mode. Full sync downloads headers backward from the tip looking for a block that is_canonical_sync recognizes. This check requires entries in CANONICAL_BLOCK_HASHES (number→hash). The background header download task stored headers via add_block_headers, which only wrote to HEADERS and BLOCK_NUMBERS but not CANONICAL_BLOCK_HASHES. This caused full sync to never find a canonical ancestor, looping endlessly with "Sync failed to find target block header" until the 8h timeout. Fix: add CANONICAL_BLOCK_HASHES write to the existing transaction in add_block_headers (which has exactly one caller: snap sync background download). --- crates/storage/store.rs | 1 + 1 file changed, 1 insertion(+) diff --git a/crates/storage/store.rs b/crates/storage/store.rs index 2632dcb1fcc..fd737807190 100644 --- a/crates/storage/store.rs +++ b/crates/storage/store.rs @@ -325,6 +325,7 @@ impl Store { let number_key = block_number.to_le_bytes().to_vec(); txn.put(BLOCK_NUMBERS, &hash_key, &number_key)?; + txn.put(CANONICAL_BLOCK_HASHES, &number_key, &hash_key)?; } txn.commit()?; Ok(()) From ee75d36354a5a4ffd3ebdce1b600d5bc4548ad90 Mon Sep 17 00:00:00 2001 From: Pablo Deymonnaz Date: Tue, 10 Feb 2026 16:03:43 -0300 Subject: [PATCH 35/36] Replace block_hashes Vec with BTreeMap to fix ordering bug The block_hashes field stored hashes without block numbers, so the numbers_and_hashes construction for forkchoice_update inferred block numbers from position (pivot_header.number - i).

Resolves the Copilot review on line 236 and the ElFantasma review on line 247. - current_head is tracked as a hash locally in the background loop (mirrors the original walk-back-via-parent_hash behaviour for the reorg case). - The sender strips the duplicate first header from each batch; receivers no longer skip(1).
