From 6bb56c04baebb5acbe978231349607a4c58b6546 Mon Sep 17 00:00:00 2001 From: pasta Date: Wed, 1 Oct 2025 12:58:34 -0500 Subject: [PATCH 01/16] Fix missing statistics updates for filter matches and relevant transactions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes two statistics tracking issues that were accidentally omitted during the wallet integration refactoring: 1. filters_matched statistic was not being incremented when filter matches were detected in sequential sync (sequential/mod.rs:1390-1398) 2. blocks_with_relevant_transactions statistic was not being incremented when the wallet found relevant transactions in blocks (block_processor.rs:238-242) Changes: - Added stats field to SequentialSyncManager struct to enable statistics updates during filter matching - Updated SequentialSyncManager::new() to accept stats parameter - Added filters_matched increment when filter match is detected - Added blocks_with_relevant_transactions increment when wallet processes relevant transactions - Updated DashSpvClient to pass stats when creating SequentialSyncManager Root cause: These statistics were tracked in old commented-out code (marked with "TODO: Re-implement with wallet integration") but were never re-added to the new simplified wallet integration code path. Result: Statistics now correctly show non-zero values for "Filters Matched" and "Blocks w/ Relevant Txs" in sync status logs, providing accurate visibility into sync progress. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- dash-spv/src/client/block_processor.rs | 6 ++++++ dash-spv/src/client/mod.rs | 1 + dash-spv/src/sync/sequential/mod.rs | 11 +++++++++++ 3 files changed, 18 insertions(+) diff --git a/dash-spv/src/client/block_processor.rs b/dash-spv/src/client/block_processor.rs index 56b00d488..58d981113 100644 --- a/dash-spv/src/client/block_processor.rs +++ b/dash-spv/src/client/block_processor.rs @@ -234,6 +234,12 @@ impl>, + + /// Statistics for tracking sync progress + stats: std::sync::Arc>, } impl< @@ -91,6 +94,7 @@ impl< received_filter_heights: SharedFilterHeights, wallet: std::sync::Arc>, chain_state: Arc>, + stats: std::sync::Arc>, ) -> SyncResult { // Create reorg config with sensible defaults let reorg_config = ReorgConfig::default(); @@ -112,6 +116,7 @@ impl< max_phase_retries: 3, current_phase_retries: 0, wallet, + stats, _phantom_s: std::marker::PhantomData, _phantom_n: std::marker::PhantomData, }) @@ -1387,6 +1392,12 @@ impl< drop(wallet); if matches { + // Update filter match statistics + { + let mut stats = self.stats.write().await; + stats.filters_matched += 1; + } + tracing::info!("🎯 Filter match found!
