From 066982227b6c5cc9b5a31aa7886b7360059fc654 Mon Sep 17 00:00:00 2001 From: Georgios Konstantopoulos Date: Mon, 2 Feb 2026 07:30:34 +0000 Subject: [PATCH 1/2] test(prune): add regression test for RETH-292 limiter accounting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a test that demonstrates the RocksDB pruning limiter issue where the limiter increments per changeset scanned from static files, not per RocksDB shard actually modified. The test creates a scenario with: - 10 blocks × 1000 changesets = 10,000 total changesets - But only 10 unique addresses (high repetition) - Limit set to 100 Expected behavior (after fix): - 10 unique addresses = 10 RocksDB shard operations - Should process all 10 blocks since 10 < 100 limit Current behavior (bug): - Stops after ~100 changesets scanned (< 1 block) - Because limiter counts input scans, not output work This test documents the current buggy behavior. After fixing the limiter to count unique addresses instead of changesets, the test assertion should be updated to verify all blocks are processed.

This caused the pruner to stop prematurely when there was high changeset repetition (e.g., popular contracts touched many times per block). Changes: - account_history.rs: Use HashMap::entry() to only increment limiter on first occurrence of each address - storage_history.rs: Use HashMap::entry() to only increment limiter on first occurrence of each (address, slot) pair - Update regression test to verify the fix works Before: 10k changesets with 10 unique addresses, limit=100 → stops at <1 block After: Same scenario → processes all 10 blocks (10 < 100 limit) Amp-Thread-ID: https://ampcode.com/threads/T-019c1ca0-1067-7584-a10b-649ca5b1c5cb Co-authored-by: Amp --- .../src/segments/user/account_history.rs | 41 ++++--- .../src/segments/user/storage_history.rs | 20 ++- scripts/patch-alloy.sh | 114 ------------------ 3 files changed, 43 insertions(+), 132 deletions(-) delete mode 100755 scripts/patch-alloy.sh diff --git a/crates/prune/prune/src/segments/user/account_history.rs b/crates/prune/prune/src/segments/user/account_history.rs index 61e3954fbb9..394083c2ae4 100644 --- a/crates/prune/prune/src/segments/user/account_history.rs +++ b/crates/prune/prune/src/segments/user/account_history.rs @@ -239,6 +239,7 @@ impl AccountHistory { Provider: DBProvider + StaticFileProviderFactory + ChangeSetReader + RocksDBProviderFactory, { use reth_provider::PruneShardOutcome; + use std::collections::hash_map::Entry; // Unlike MDBX path, we don't divide the limit by 2 because RocksDB path only prunes // history shards (no separate changeset table to delete from).
