18-25: Consider serialization for PeerStats
If you anticipate additional or more complex reporting, derivingSerialize(or partial equivalents) forPeerStatscould simplify expansions to JSON or other formats.
112-112: Consider function refactoring
#[allow(clippy::too_many_lines)]hints thathandle_stator surrounding logic might benefit from modularization for clarity and maintainability.
249-280: Verbose logging
The expandedinfo!statement is helpful for debugging, but it may produce lengthy logs. If logs become unwieldy, consider condensing or gating them.

127-129: Good implementation of the diagnostic mode flagThe new
diagnostic_modefield is well-defined with a clear documentation comment explaining its purpose. The command-line flag implementation provides flexibility with long form (--diagnostic-mode), short form (-d), and alias (--diag), making it user-friendly.p2pool/src/server/p2p/peer_store.rs (9)
345-352: Good refactoring to centralize peer statistics collectionThe
update_peer_statsmethod nicely consolidates the peer statistics collection logic in one place, simplifying the code and reducing redundancy.
116-117: Appropriate use of refactored methodGood utilization of the new centralized
update_peer_statsmethod when updating the peer lists.
300-301: Appropriate use of refactored methodConsistently calling
update_peer_statsafter modifying the greylist for seed peers.
319-320: Appropriate use of refactored methodProperly updating peer statistics after modifying the non-squad peers list.
340-343: Good implementation of diagnostic logicThe code properly updates peer statistics after adding a new peer to the whitelist and includes debug logging for new peers.
367-368: Appropriate use of refactored methodCorrectly updates peer statistics after clearing the grey list.
377-378: Appropriate use of refactored methodCorrectly updates peer statistics after clearing the blacklist.
388-389: Appropriate use of refactored methodCorrectly updates peer statistics after moving a peer to the grey list.

1117-1130: Enhanced peer statistics collectionGood enhancement to store the seed peer status in a variable and use it for both the disconnection logic and for sending detailed statistics. The
send_peer_statscall provides valuable diagnostic information including whether the peer is a seed, the peer ID, addresses, and number of peers added.p2pool/src/cli/commands/util.rs (1)
182-192: Well-implemented conditional diagnostic data collectionThis implementation correctly sets up the diagnostic mode based on the command-line flag. When enabled, it collects the local peer ID and network addresses (both listeners and external) and passes them to the stats collector. The conditional approach ensures that diagnostic data is only collected when explicitly requested.
integration_tests/src/p2pool_process.rs (2)
174-174: Confirm if always-on diagnostic mode is intended
By settingdiagnostic_modetotrueby default, you may introduce additional overhead in most test scenarios. Consider parameterizing this or verifying that the extra logging is needed in all runs.
383-386: CLI flag injection looks good
Appending--diagnostic-modewhenargs.diagnostic_modeis true ensures the diagnostic mode is exposed via the command line. Looks appropriate for your use case.p2pool/src/server/http/stats_collector.rs (9)
4-4: Check concurrency when writing files
UsingFileandWriteis fine, but ensure no other concurrent process attempts to open or write to the same file without coordination, which could cause race conditions or partial overwrites.
7-7: Core dependencies for peer information
taking PeerId and Multiaddr from libp2pis typical for p2p scenarios. No issues spotted.
59-60: Validate reason for storing (PeerId, Vec)
Storing this tuple indiagnostic_modemight be overkill if only the local peer’s addresses are needed. Confirm that both items are always required.
64-68: Constructor signature extension
Addingdiagnostic_modetoStatsCollector::newcleanly integrates your optional CSV feature without breaking existing usage.
101-102: Properly initializing new fields
Initializing bothdiagnostic_modeandpeer_statsin the constructor ensures consistent usage within the collector.
164-178: PeerStats match arm
This branch forPeerStatsintegrates seamlessly into the existing enumeration and updates the internalHashMap. The logic looks correct.
225-239: Diagnostic timer initialization
The conditional 60-second interval is well-handled, ensuring no overhead unlessdiagnostic_modeis enabled.
281-312: File creation and overwriting
Writing to"peer_connectivity_stats.csv"on each interval could overwrite data. Make sure this behavior is intentional or consider appending with a timestamp-based filename for historical records.
416-422: New PeerStats variant
AddingPeerStatsto theStatDataenum aligns well with your new diagnostic features, offering a structured way to broadcast peer-centric data.

p2pool/src/server/http/stats_collector.rs (1)
252-340: Implemented periodic diagnostic reporting to CSV file.The code creates a timer that periodically writes peer statistics to a CSV file for later analysis. While functional, there are some areas for improvement:
- Error handling is minimal - using
let _unused = writeln!()ignores write errors- The file is reopened on every timer tick, which could be inefficient
- There's no file rotation or size management for long-running instances
Consider enhancing the file I/O with better error handling and potentially implementing file rotation:
- if let Ok(mut file) = File::create("peer_connectivity_stats.csv") { - let _unused = writeln!( - file, - "PeerId: {}, Addresses: {}", - peer_id.to_base58(), - self.local_peer_addresses.iter().map(|a| a.to_string()).collect::<Vec<String>>().join(",") - ); - // ... more writes ... - let _unused = file.flush(); - } + let result = File::create("peer_connectivity_stats.csv").and_then(|mut file| { + writeln!( + file, + "PeerId: {}, Addresses: {}", + peer_id.to_base58(), + self.local_peer_addresses.iter().map(|a| a.to_string()).collect::<Vec<String>>().join(",") + )?; + // ... more writes ... + file.flush()?; + Ok(()) + }); + if let Err(e) = result { + error!(target: LOG_TARGET, "Failed to write diagnostic report: {}", e); + }

p2pool/src/server/config.rs (2)
29-29: Added diagnostic mode timer configuration field.This field adds support for configuring the interval at which diagnostic data will be collected, allowing customization of the connectivity monitoring process.
51-51: Added reasonable default value for diagnostic_mode_timer.The default value of 60 seconds provides a good balance between collecting enough diagnostic data and preventing excessive resource usage.
p2pool/src/server/server.rs (1)
120-121: Initializing local peer addresses in stats client.This change updates the statistics broadcast client with the node's local addresses during initialization, ensuring that connectivity diagnostics have access to address information from the start.
p2pool/src/server/p2p/network.rs (2)
409-413: Added method to aggregate local peer addresses.This well-implemented method consolidates both external and listener addresses into a single collection, making it easier to track and report node connectivity information.
1100-1108: Improved peer statistics collection.The code now stores the result of checking if a peer is a seed peer in a variable and reuses it, reducing duplicate computations. It also sends comprehensive peer statistics to the broadcast client, enhancing the connectivity diagnostics feature.
p2pool/src/cli/commands/util.rs (1)
182-193: Implemented conditional diagnostic mode configuration.The code now properly configures the diagnostic mode based on user arguments. When enabled, it sets up the diagnostic process with the configured timer interval and local peer ID, which will be used for CSV reporting of connectivity statistics.
Worth noting that the implementation elegantly handles both the enabled and disabled states through the Option type.
integration_tests/src/p2pool_process.rs (4)
78-78: Added diagnostic mode timer configuration.This setting configures how frequently diagnostic data will be collected and written to file (every 10 seconds). This aligns well with the PR objective of collecting connectivity diagnostics.
175-175: Enabled diagnostic mode in integration tests.Enabling diagnostic mode by default in integration tests is a good approach as it ensures the feature is regularly tested and any regressions would be caught quickly.
384-386: Added command-line handling for the diagnostic mode flag.This implementation integrates the diagnostic mode flag into the command-line arguments system, following the same pattern as other Boolean flags. The logic is sound and consistent with the rest of the codebase.
496-501: Improved logging during peer connection verification.The logging interval has been changed from every 10 iterations to every 50, reducing log verbosity. Including the elapsed time in the log message provides valuable context for troubleshooting connectivity issues.
integration_tests/tests/features/Sync.feature (3)
8-8: Clarified scenario title to specify startup sync.The scenario name now more accurately reflects that it's testing sync behavior specifically during startup. This improves test clarity and documentation.
15-22: Enhanced peer connectivity testing.Added more test nodes (NODE_C and NODE_D) and explicit verification steps for connectivity between them. This provides more comprehensive test coverage for the peer connection logic, which is particularly valuable given the new diagnostic features.
24-36: Added scenario to test block loading after restart.This new scenario tests a critical aspect of node behavior: correctly reloading blocks from storage after a restart. This is an excellent addition that ensures data persistence, which becomes even more important when diagnostic data is being collected and analyzed across restarts.
p2pool/src/server/http/stats_collector.rs (7)
19-26: Added PeerStats structure for collecting connectivity diagnostics.This new structure encapsulates all relevant peer connectivity information including seed peer status, ID, addresses, message counts, and timestamps. The design is clean and well-organized.
60-62: Added diagnostic mode tracking to StatsCollector.These new fields store the diagnostic mode configuration and collected peer statistics. The implementation allows for optional diagnostic mode operation, making it a non-breaking change.
66-70: Updated constructor to support diagnostic mode.The constructor now accepts an optional diagnostic mode parameter, which enables the feature without requiring changes to existing code that doesn't use diagnostics. This is a good approach for backward compatibility.
167-205: Added handler for peer statistics.The implementation correctly handles both new and existing peer statistics, preserving appropriate data when updating existing entries. The logic for updating message counts and timestamps is well-thought-out.
444-454: Added StatData enum variants for peer diagnostics.These new variants extend the existing event system to support diagnostic data collection. The implementation is consistent with the existing pattern and well-integrated.
479-480: Updated timestamp method for new enum variants.This method update ensures that the timestamp functionality remains consistent across all event types, including the new diagnostic events. This is proper maintenance of the codebase.
589-611: Added methods to update peer statistics.These methods provide a clean API for updating local peer addresses and sending peer statistics. The implementation follows the established pattern and maintains consistency.
- Added a command-line option to perform diagnostics upon startup. Various statistics will be collected as they are encountered and written to a file once populated. - Added more cucumber tests

368-379: 🛠️ Refactor suggestionDuplicate Exemption Entries for Clap
Within the configuration, there appear to be multiple exemption entries forclap:
• An unannotated block with version "2.34.0" (lines 368–371)
• An updated block (lines 372–375) with version "3.2.25"
• Another block (lines 376–379) with version "4.5.28"This redundancy could lead to ambiguity as to which version is being enforced.
Please review and consolidate these entries to ensure consistency.
1072-2611: 🛠️ Refactor suggestionGeneral Review of the Updated Exemption Entries
This configuration file has been overhauled with a very large number of exemption entries—each specifying a fixed version and the same "safe-to-deploy" criteria. In addition to many individual updates and additions noted above, please review the following points:• Version Changes & Downgrades:
– Notably, thehashbrownexemption (lines 828–831) now pins version "0.14.5" (a downgrade from the previous "0.15.2"). Verify that this change is intentional and supported by security reviews.• Duplicate/Multiple Entries:
– Several libraries (e.g.,clap,clap_derive,convert_case) appear more than once with differing version numbers. It is important to consolidate these so the tool using this configuration isn’t confused by conflicting entries.• Consistency Across Exemptions:
– The overall pattern (version and criteria) is consistent; however, given the sheer volume of changes, it is advisable to run an automated check (or review via your dependency management tool) to ensure that every exemption aligns with upstream advisory recommendations and that no inadvertent regressions have been introduced.Overall, the structured approach is commendable. A careful verification is recommended to ensure that all these version updates and duplicate entries are correct and intentional.

144-147: Second entry for argon2There's another entry for
argon2with version "0.5.3" in addition to the existing one at version "0.4.1" (lines 140-143).While having multiple versions is sometimes necessary for different component dependencies, consider consolidating to the newer version if possible.
p2pool/src/server/http/stats_collector.rs (2)
167-199: Consider simplifying the peer stats update logic.The current implementation has nested conditionals for updating existing entries. This could be simplified for better readability while maintaining the same functionality.
- if let Some(current_entry) = self.peer_stats.get(&peer_id.to_base58()) { - self.peer_stats.insert(peer_id.to_base58(), PeerStats { - peer_is_a_seed_peer, - peer_id, - public_addresses, - number_received: if number_received > 0 { - number_received - } else { - current_entry.number_received - }, - timestamp: if number_received > 0 { - timestamp - } else { - current_entry.timestamp - }, - }); - } else { - self.peer_stats.insert(peer_id.to_base58(), PeerStats { - peer_is_a_seed_peer, - peer_id, - public_addresses, - number_received, - timestamp, - }); - } + let entry = self.peer_stats.entry(peer_id.to_base58()).or_insert_with(|| PeerStats { + peer_is_a_seed_peer, + peer_id, + public_addresses: public_addresses.clone(), + number_received: 0, + timestamp: EpochTime::now(), + }); + + // Update fields - only update number_received and timestamp if we have a new count + entry.peer_is_a_seed_peer = peer_is_a_seed_peer; + entry.public_addresses = public_addresses; + if number_received > 0 { + entry.number_received = number_received; + entry.timestamp = timestamp; + }
298-333: Consider parameterizing the diagnostic file path.The current implementation writes to "peer_connectivity_stats.csv" in the current directory. Consider making this path configurable or using a specific directory to avoid potential permission issues or file conflicts.
Also, be cautious about the timestamp conversion at line 315. While you have a fallback to i64::MAX if the conversion fails, it might be more intuitive to handle extremely large timestamps differently.

92-95: New security exemptions added for cryptographic librariesThe addition of new exemptions for cryptographic libraries like
aes-kwis consistent with improving the codebase's security posture. These exemptions properly follow the established pattern in the file.
384-387: Clap_derive version exemptionThe exemption for
clap_deriveversion "3.2.25" has already been noted in a previous review, and an issue has been created to track it (tari-project/tari#6870).
452-455: Multiple convert_case versionsAs previously confirmed, the multiple
convert_caseversions are intentionally kept separate since they're used by different components (tari_commonuses v0.6.0 whilecucumber v0.20.2uses v0.4.0 for tests).
508-511: Cucumber test dependencies addedThe addition of cucumber-related exemptions (
cucumber,cucumber-codegen,cucumber-expressions, and updatedgherkin) aligns well with the PR objective of adding more cucumber tests for improved test coverage.Also applies to: 512-515, 516-519, 792-795

1116-1120: The update to seed peer checking is clean and straightforward.The direct check if a peer is a seed peer within the if condition is an improvement over potentially storing an intermediate variable. This makes the code more direct and easier to follow.
integration_tests/src/p2pool_process.rs (4)
78-78: New diagnostic_mode_timer configuration looks good.Adding this configuration parameter with a value of 10 seconds enables regular diagnostic information collection, which will improve debugging capabilities.
175-175: Appropriate enablement of diagnostic mode in StartArgs.Setting diagnostic_mode to true ensures that the new diagnostic functionality will be active during integration tests, which is valuable for capturing detailed connection statistics.
384-386: Good implementation of command line argument handling for diagnostic mode.The conditional addition of the --diagnostic-mode flag when args.diagnostic_mode is true ensures proper command-line parameter passing to the underlying process.
496-501: Improved debug logging with less verbosity and better timing information.Changing the debug log frequency from every 10 to every 50 iterations reduces log noise, and including the elapsed time provides valuable context about how long the connection attempt has been running.
p2pool/src/server/http/stats_collector.rs (4)
20-26: Well-structured PeerStats struct to capture peer connection statistics.The new PeerStats struct effectively encapsulates all the necessary peer information including seed peer status, peer ID, addresses, message counts, and timestamps.
66-70: Good enhancement to StatsCollector constructor with diagnostic mode support.The addition of the diagnostic_mode parameter allows for conditional diagnostic data collection, making the feature opt-in rather than always-on.
437-447: Good addition of new StatData variants.The addition of PeerStats and LocalPeerAddresses variants to the StatData enum provides clear structure for the new types of statistics being collected.
472-473: Properly updated timestamp method to handle new variants.The timestamp method correctly implements handling for the new StatData variants, ensuring consistent behavior across all variants.
