This commit removes the obsolete terminal block system that was previously
used for sync optimization but has been superseded by sequential sync.

Changes:
- Remove all terminal block storage methods from StorageManager trait
- Remove StoredTerminalBlock type and related data structures
- Delete terminal block data files (mainnet/testnet JSON files)
- Remove terminal block sync modules and managers
- Clean up backup files (.backup, _old.rs)
- Remove unused terminal block tests and examples
- Remove terminal block documentation

The dash-spv binary continues to work correctly, reaching sync height
of 1306349+ on testnet as verified by testing.

swift-dash-core-sdk/build-ios.sh (5)

14-16: Fix brittle repo navigation (cd ../) to be robust regardless of CWD

Using cd ../ assumes the script is invoked from swift-dash-core-sdk/. Use the script’s directory to locate the repo root to avoid accidental traversal outside the repo.

Apply this diff:

-# Navigate to rust project root
-cd ../
+# Navigate to repo root relative to this script
+SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+REPO_ROOT="$SCRIPT_DIR/.."
+cd "$REPO_ROOT"

79-80: Return to the swift directory via SCRIPT_DIR instead of a hardcoded path

This complements the repo-root fix and makes the script immune to invocation path differences.

-# Navigate back to swift directory
-cd swift-dash-core-sdk
+# Navigate back to swift directory
+cd "$SCRIPT_DIR"

4-5: Harden the script with strict mode and an error trap

Enable nounset and pipefail and add a simple trap for non-cargo failures (e.g., lipo/cp) to emit a clear error.

-set -e
+set -Eeuo pipefail
+trap 'ec=$?; printf "%bError: build script failed with exit code %d%b\n" "${RED-}" "$ec" "${NC-}"; exit "$ec"' ERR

17-22: Add preflight checks for required tools before proceeding

Failing early with a clear message is better than cryptic errors later.

257-258: Fix critical race condition in storage segment initialization

The ensure_segment_loaded method is called without locks during storage initialization, but the method attempts to acquire locks internally. This can lead to race conditions when multiple segments are loaded concurrently during initialization. The pattern of dropping and re-acquiring locks between metadata loading and segment loading introduces a window where concurrent operations can interfere.

Consider serializing segment loading during initialization or using a more robust locking pattern that holds locks consistently through the initialization process.


1285-1330: Clarify get_header height semantics and surface blockchain-relative API

We verified that get_header is invoked extensively—both in tests and production code—and callers must always supply a storage-relative index. For example, in src/sync/masternodes.rs you see:

// Convert blockchain heights to storage indices for storage.get_header()
let storage_validation_height = if validation_height >= sync_base_height {
    validation_height - sync_base_height
} else {
    // handle underflow
};
let base_header = storage.get_header(storage_validation_height).await?;

Manually converting at every call site is error-prone. To improve UX and avoid subtle bugs, please choose one of the following:

  • Rename the existing method to make its contract explicit (e.g.,
    get_header_by_storage_index) and introduce a deprecated alias for backward compatibility.
  • Add a new method, get_header_by_blockchain_height(blockchain_height: u32), that computes the storage index internally before calling into your segment logic.
  • Overload or extend get_header (e.g., with an enum parameter) so it can distinguish and handle both blockchain and storage heights in one API.

Whichever option you pick, update call sites or preserve an alias layer to avoid breaking all of the existing usages.

dash-spv/src/client/watch_manager_test.rs (1)

331-332: Potential deadlock risk with nested Arc for storage

Wrapping the storage in Arc<tokio::sync::Mutex<Box<dyn StorageManager>>> creates a complex ownership pattern that could lead to deadlocks if the storage is locked while another operation tries to acquire it. The test spawns multiple concurrent tasks that all need to lock the same storage.

Consider using a storage implementation that supports concurrent access internally, or restructure the test to avoid the nested mutex pattern:

-        let (watch_items, wallet, updater, storage) = setup_test_components().await;
-        let storage = Arc::new(tokio::sync::Mutex::new(storage));
+        // Use a shared storage that handles concurrency internally
+        let storage = Arc::new(RwLock::new(MemoryStorageManager::new().await.unwrap()));
+        let watch_items = Arc::new(RwLock::new(HashSet::new()));
+        let wallet_storage = storage.clone();
+        let wallet = Arc::new(RwLock::new(Wallet::new(wallet_storage)));
+        let (tx, _rx) = mpsc::unbounded_channel();
+        let updater = Some(tx);
🧹 Nitpick comments (24)
dash-spv/tests/error_types_test.rs (1)

59-66: Consider simplifying with if let and reusing the captured msg in the assertion

A concise alternative that also avoids moves and reduces nesting:

-    match &spv_err {
-        SpvError::Storage(StorageError::Corruption(msg)) => {
-            assert_eq!(msg, "Header checksum mismatch");
-            assert!(spv_err.to_string().contains("Header checksum mismatch"));
-        }
-        _ => panic!("Expected SpvError::Storage variant"),
-    }
+    if let SpvError::Storage(StorageError::Corruption(msg)) = &spv_err {
+        assert_eq!(msg, "Header checksum mismatch");
+        assert!(spv_err.to_string().contains(msg));
+    } else {
+        panic!("Expected SpvError::Storage variant");
+    }

23-41: Good centralization; prefer printf over echo -e for portability

printf avoids echo -e quirks and is standard across environments.

-# Function to run cargo build with output suppression
+# Function to run cargo build with output suppression
 run_cargo_build() {
     local target=$1

43-56: DRY the per-target/package builds with loops to reduce duplication

This keeps the list of packages/targets in one place and makes future changes less error-prone.

29-29: Consider adding documentation for the public helper function.

Since create_mock_mn_list_diff is now public and likely to be used across multiple modules, consider adding documentation to clarify its purpose and usage parameters.

    /// Create a mock MnListDiff for testing

+   /// # Arguments
+   /// * `_height` - The height parameter (currently unused in mock creation)

dash-spv/src/client/mod.rs (2)

3180-3183: API exposure: consider returning Arc clone and documenting side effects

Exposing the ChainLockManager publicly is reasonable for engine-driven flows, but returning a reference to the Arc is slightly awkward for consumers and invites out-of-band mutations without guidance. For API consistency (e.g., get_terminal_ui clones its Arc), prefer returning an Arc clone and explicitly document intended read vs write usage and invariants.

Also, please document that client-level processing (events, state updates) should prefer the client methods (e.g., process_chainlock, update_chainlock_validation) to avoid bypassing invariants.

Apply this diff for ergonomic consistency:

-    /// Get reference to chainlock manager
-    pub fn chainlock_manager(&self) -> &Arc<ChainLockManager> {
-        &self.chainlock_manager
-    }
+    /// Get a handle to the ChainLock manager.
+    /// Note: Prefer client methods for ChainLock processing to preserve invariants.
+    pub fn chainlock_manager(&self) -> Arc<ChainLockManager> {
+        self.chainlock_manager.clone()
+    }

3185-3188: Public storage accessor: document thread-safety expectations

Making the read-only storage accessor public widens the surface for concurrent access. Given StorageManager is Send + Sync but often relies on interior mutability (per team learnings), explicitly document thread-safety expectations and acceptable call contexts (e.g., safe to call while client is running; do not assume atomicity across multiple calls).

Would you like me to add a short doc comment block here clarifying thread-safety and intended usage?

dash-spv/REMOVAL_PLAN.md (2)

6-6: Fix markdown heading trailing punctuation (MD026)

Remove the trailing colon to satisfy markdownlint MD026.

Apply:

-## Methods to Remove (with line numbers):
+## Methods to Remove (with line numbers)

8-18: Replace brittle line-number references with search anchors

Line numbers will drift quickly. Prefer stable identifiers (method names) and “Find Usages” instructions over exact line ranges to reduce maintenance overhead and the risk of incorrect removals.

32-44: Call out breaking API changes explicitly

Given the large removal, add a “Breaking Changes” subsection enumerating removed public methods/types and suggested migration paths. This helps downstream users and CI consumers.

I can draft the section if you provide the current public signatures detected by cargo doc.

1214-1245: Align proposed StorageManager extensions with existing naming

Current code already has methods like get_header_height_by_hash and load_headers(range). The proposed names (get_block_height/get_block_hash) should align with existing ones to avoid duplication and churn. Also, evaluate whether height lookups belong in storage vs. chain state to keep responsibilities clear.

Would you like me to map the proposed methods to the existing trait and produce a minimal-diff naming plan?


1-22: Markdown linting: list indentation and heading position

The document triggers multiple markdownlint warnings (MD007, MD023, MD046). If the repo enforces these, adjust list indentation to the left margin, ensure headings start at column 0, and pick a consistent code block style (or configure markdownlint to allow fenced blocks).

I can provide a cleaned version if these rules are enforced in CI.

PHASE_3_IMPLEMENTATION.md (1)

58-76: Quantified claims: add footnotes or benchmarks

Claims like “>80% reduction in sync time” should be backed by benchmark notes (hardware, network conditions, dataset). Add a short appendix or footnote to maintain credibility.

I can draft a small “Benchmark Notes” section template.

40-42: Missing documentation for the as_any method

The as_any method is part of the NetworkManager trait implementation but lacks documentation explaining its purpose in enabling downcasting.

+    /// Returns a reference to the underlying type for downcasting purposes.
     fn as_any(&self) -> &dyn std::any::Any {
         self
     }

186-189: Dead code with misleading comment

These lines are commented out but remain in the codebase. The comment indicates that storage_mut() is not available in the current API, making these lines dead code that should be removed entirely.

-    // Add a test header to storage
     let genesis = genesis_block(Network::Dash).header;
-    // Note: storage_mut() is not available in current API
-    // let storage = client.storage_mut();
-    // storage.store_header(&genesis, 0).await.unwrap();
+    // TODO: Add a test header to storage when storage_mut() API becomes available

409-416: Large block of commented code in test

Multiple lines of code setting the sync manager phase are commented out. If this functionality is needed for the test, it should be properly implemented or removed entirely.

-    // Simulate masternode sync by manually setting sequential sync state
-    // In real usage, this would happen automatically during sync
-    // Note: sync_manager is private, can't access directly
-    // client.sync_manager.set_phase(dash_spv::sync::sequential::phases::SyncPhase::FullySynced {
-    //     sync_completed_at: std::time::Instant::now(),
-    //     total_sync_time: Duration::from_secs(10),
-    //     headers_synced: 1000,
-    //     filters_synced: 0,
-    //     blocks_downloaded: 0,
-    // });
+    // TODO: Simulate masternode sync when sync_manager API becomes accessible
dash-spv/src/storage/disk.rs (2)

874-876: Optimize background save trigger logic

The condition for triggering background saves uses an OR operator that may cause unnecessary saves. When headers.len() >= 1000, the second condition blockchain_height % 1000 == 0 is redundant. Additionally, using blockchain_height (which continues from checkpoint sync) instead of the number of headers processed may trigger saves at unexpected intervals.

Consider simplifying the logic:

-        // Save dirty segments periodically (every 1000 headers)
-        if headers.len() >= 1000 || blockchain_height % 1000 == 0 {
+        // Save dirty segments periodically (every 1000 headers)
+        if headers.len() >= 1000 || (headers.len() < 1000 && storage_index % 1000 == 0) {
             self.save_dirty_segments().await?;
         }

1019-1026: Improve sentinel header detection efficiency

The sentinel header detection logic checks multiple fields individually. Consider using a dedicated method or constant for cleaner, more maintainable code.

Add a helper method:

+impl BlockHeader {
+    fn is_sentinel(&self) -> bool {
+        self.version.to_consensus() == i32::MAX
+            && self.time == u32::MAX
+            && self.nonce == u32::MAX
+            && self.prev_blockhash == BlockHash::from_byte_array([0xFF; 32])
+    }
+}

         for header in headers {
             // Skip sentinel headers (used for padding)
-            if header.version.to_consensus() == i32::MAX
-                && header.time == u32::MAX
-                && header.nonce == u32::MAX
-                && header.prev_blockhash == BlockHash::from_byte_array([0xFF; 32])
-            {
+            if header.is_sentinel() {
                 continue;
             }

211-212: Unused storage variable creates confusion

A new Box<dyn StorageManager> is created on line 212 but it's not used - the handler methods receive the mutable reference to the boxed storage from line 213. This creates two separate storage instances which could lead to confusion.

Remove the redundant storage creation:

         let (tx, mut rx) = mpsc::unbounded_channel();
-        let mut storage =
-            Box::new(MemoryStorageManager::new().await.unwrap()) as Box<dyn StorageManager>;
 
         let address = create_test_address();

Then update the method calls to use a properly initialized storage from the beginning of the test.

145-146: Test assertion doesn't match the comment

The comment mentions checking transactions_processed field, but the code checks last_activity instead, indicating the field doesn't exist in the current SpvStats structure.

Update the comment to match the actual check:

         // Check stats were updated
         let stats_guard = stats.read().await;
-        // transactions_processed field doesn't exist, check other stats
+        // Check that activity was recorded
         assert!(stats_guard.last_activity.elapsed().as_secs() < 1);
dash-spv/src/client/message_handler_test.rs (1)

17-20: Duplicate import of dashcore::Network

The Network type is imported twice - once on line 17 and again on line 23. This creates confusion and potential compilation warnings.

Remove the duplicate import:

     use crate::validation::ValidationManager;
     use crate::wallet::Wallet;
-    use dashcore::Network;
-    use std::collections::HashSet;
-    use std::sync::Mutex;
     use dashcore::block::Header as BlockHeader;
     use dashcore::network::message::NetworkMessage;
     use dashcore::network::message_blockdata::Inventory;
     use dashcore::{Block, BlockHash, Network, Transaction};
     use dashcore_hashes::Hash;
+    use std::collections::HashSet;
+    use std::sync::Mutex;
     use std::sync::Arc;

Learning: The `StorageManager` trait in `dash-spv/src/storage/mod.rs` uses `&mut self` methods but is also `Send + Sync`, and implementations often use interior mutability for concurrency. This can be confusing, so explicit documentation should clarify thread-safety expectations and the rationale for the API design.

Learning: Passing exclusive mutable references to network and storage managers into the sync manager in async Rust can lead to borrow checker issues or runtime contention if concurrent access is needed elsewhere. It's advisable to document this architectural tradeoff and consider refactoring to interior mutability or message passing for shared access as the codebase evolves.

59-66: Correctly borrowing scrutinee to avoid move; fixes partial-move compile error

Matching on &spv_err ensures msg is borrowed (not moved) and allows using spv_err within the arm. This is the right fix here.

dash-spv/src/sync/validation_test.rs (2)

37-37: LGTM! Good visibility improvement for cross-module testing.

Making the create_mock_mn_list_diff function public enables reuse across different test modules, which aligns well with the broader testing enhancements mentioned in the PR summary. This change improves code reusability and reduces duplication in test utilities.


235-235: LGTM! Correct usage of the newly public function.

The update to use super::tests::create_mock_mn_list_diff properly references the function through its new public module path. This maintains the existing functionality while adapting to the visibility change.

dash-spv/src/network/tests.rs (1)

21-22: LGTM: Simplify hash construction.

The change from BlockHash::all_zeros() to BlockHash::from([0u8; 32]) is a valid refactoring that produces the same zero hash result. Both methods create a hash with all zero bytes, but the new approach is more explicit about the byte array construction.

dash-spv/src/sync/sequential/mod.rs (1)

846-846: LGTM: Comment improvement for clarity.

The comment change from "for DKG window checking" to "during masternode sync" provides a clearer, more general description of when blocks are allowed during the masternode list downloading phase. This makes the code more maintainable and easier to understand.

dash-spv/src/client/config_test.rs (3)

69-69: LGTM: Test reflects config API changes.

The change from ValidationMode::CheckpointsOnly to ValidationMode::Basic aligns with the broader PR objectives of simplifying the configuration API. This test change correctly reflects the updated validation mode options.


85-85: LGTM: Assertion updated correctly.

The assertion correctly matches the updated validation mode being tested in line 69.


272-274: LGTM: Refactor to more explicit config modification.

The change from method chaining to explicit field assignment followed by a builder method call is more readable and makes the test logic clearer. The mutable approach allows for better step-by-step configuration building.

dash-spv/tests/qrinfo_integration_test.rs (1)

134-138: LGTM: Test reflects simplified QRInfo configuration API.

The test correctly uses the new configuration builders for QRInfo settings, focusing only on the remaining configuration options (qr_info_extra_share and qr_info_timeout) after the removal of the boolean toggle flags.

  2. Key files: Both new implementations and modified existing files
  3. Implementation details: Correct engine method signatures and error handling patterns
  4. Risk mitigation: Addresses all identified risks from the planning phase

The documentation follows a professional structure and provides actionable next steps for manual cleanup and integration.

🛠️ Refactor suggestion

Weak assertion in block processing test

The test only checks that height >= 0, which is always true for unsigned integers. This doesn't validate that the correct height was emitted in the event.

Store the expected height and validate it properly:

+        let expected_height = 0; // Or calculate based on test setup
         // Check event was sent
         match event_rx.recv().await {
             Some(SpvEvent::BlockProcessed {
                 height,
                 ..
             }) => {
-                // We can't check block_hash directly as it's not in the event
-                assert!(height >= 0);
+                assert_eq!(height, expected_height, "Block processed at unexpected height");
             }
             _ => panic!("Expected BlockProcessed event"),

currently asserts only that `height >= 0` which is meaningless for unsigned
types; capture the expected block height (e.g., the height used to create or
process the block) into a variable and replace the weak assertion with a precise
equality/assertion against the emitted event's height (for example
assert_eq!(emitted_height, expected_height) or matching the event payload field
to the expected value). Ensure you extract the height from the event struct/enum
correctly and use the appropriate assertion macro to validate the exact height.

Incomplete test due to inaccessible private fields

Multiple tests in this file are incomplete because they can't access private fields (processed_blocks, failed). The tests either skip critical validation or simulate behavior without actually testing it. This significantly reduces test coverage quality.

Consider refactoring the BlockProcessor to expose necessary test hooks or state inspection methods:

  1. Add a test-only method to check if a block has been processed
  2. Add a method to query the processor's health/failed state
  3. Use a test configuration that makes these fields accessible

Would you like me to generate a refactored version that properly tests these scenarios while maintaining encapsulation?

are incomplete because they can't inspect private fields like processed_blocks
and failed; add small test-only accessors on the BlockProcessor to expose the
minimal state needed for assertions (for example #[cfg(test)] pub(crate) fn
is_block_processed(&self, id: BlockId) -> bool and #[cfg(test)] pub(crate) fn
has_failed(&self) -> bool) or similar query methods scoped with cfg(test) so
production encapsulation is preserved, then update the tests to call these
accessors to validate duplicate detection and failure states.

Incomplete transaction event verification

The test doesn't actually verify that the transaction event was emitted because it uses the event sender instead of a receiver. This leaves a gap in test coverage for mempool transaction handling.

Create a proper event receiver to verify the event:

-        let mut handler = MessageHandler::new(
+        let (event_tx, mut event_rx) = mpsc::unbounded_channel();
+        let handler = MessageHandler::new(

⚠️ Potential issue

Test is completely skipped without explanation

The test returns early without any assertion or actual test logic. If the InstantLock message type varies by dashcore version, the test should either be conditionally compiled or properly handle version differences.

Either remove the test entirely or make it conditional:

+    #[cfg(feature = "instantlock_v2")]  // Or appropriate feature flag
     #[tokio::test]
     async fn test_handle_instantlock_message() {
         // ... setup code ...
 
-        // Skip InstantLock test - message type varies by dashcore version
-        return;
-
-        // Handle the message
-        let result = handler.handle_network_message(message).await;
-        assert!(result.is_ok());
+        // Create appropriate InstantLock message based on version
+        let instant_lock = create_test_instant_lock();
+        let message = NetworkMessage::IsLock(instant_lock);

…pv-data

Changes the default data directory behavior to create unique temporary
directories in /tmp rather than using ./dash-spv-data in the project
directory. This prevents cluttering the workspace and aligns with test
behavior.

- Default: Creates /tmp/dash-spv-{timestamp}-{pid} directory
- Explicit: --data-dir flag still works for custom paths
- Tests: Already use TempDir and are unaffected

Learning: The `StorageManager` trait in `dash-spv/src/storage/mod.rs` uses `&mut self` methods but is also `Send + Sync`, and implementations often use interior mutability for concurrency. This can be confusing, so explicit documentation should clarify thread-safety expectations and the rationale for the API design.

653-654: LGTM! Terminal block API removal correctly implemented.

The removal of terminal block methods from the StorageManager trait is correctly reflected in the mock implementation. The comments clearly indicate that these methods are no longer part of the trait, which aligns with the broader refactor described in the AI summary.

dash-spv/tests/error_handling_test.rs (1)

381-382: LGTM! Consistent terminal block API removal.

The terminal block methods have been properly removed from this mock implementation as well, maintaining consistency with the StorageManager trait changes. The explanatory comments are clear and appropriate.

dash-spv/src/main.rs (2)

145-156: LGTM! Well-implemented default data directory generation.

The implementation correctly creates unique temporary directories using timestamp and process ID to avoid collisions. The approach is robust and handles the case when no data directory is provided.


158-158: Good use of clone() for preserving the original PathBuf.

Using data_dir.clone() here is appropriate as it allows the original data_dir to be used later for logging while passing the cloned path to the configuration.

Verify consistency with existing logging pattern.

The new logging statement provides useful information about the data directory being used. However, there's already similar logging at lines 207-209 that conditionally logs the storage path from config.

Let me check if this creates duplicate logging:


🏁 Script executed:

#!/bin/bash
# Description: Check for potential duplicate logging of data directory information
# Expected: Find both logging statements to assess if they're redundant

echo "=== Searching for data directory logging patterns ==="
rg -A 2 -B 2 "data.directory|storage.path|Using data directory" --type rust

Consolidate duplicate data‐directory logging

There are two calls that log the same path back‐to‐back in dash-spv/src/main.rs, and one of them actually occurs before logging is initialized. To avoid redundancy (and ensure the log is captured), please refactor as follows:

• Remove the conditional pre-initialization log (around line 212):

if let Some(path) = config.storage_path.as_ref() {
    tracing::info!("Data directory: {}", path.display());
}

• Move dash_spv::init_logging(log_level)?; above the first tracing::info! calls, then keep a single, clear statement:

dash_spv::init_logging(log_level)?;
// …
tracing::info!("Using data directory: {}", data_dir.display());

This ensures the data directory is logged exactly once, after logging is set up.
