⚠️ Issue Found: Improper Timeout ConfigurationThe timeout value in
PingConfigis set to0milliseconds, which can cause immediate timeout and lead to premature termination of the heartbeat.
- File:
transport/network/src/ping.rs
- Line:
pub timeout: std::time::Duration, // Duration -> should be in millis- Usage:
timeout: std::time::Duration::from_millis(0),Recommendations:
- Update Timeout Value:
- Replace
std::time::Duration::from_millis(0)with a sensible non-zero duration to prevent immediate timeouts. For example:timeout: std::time::Duration::from_millis(150),- Review Other Timeout Configurations:
- Ensure all timeout settings across the codebase use appropriate non-zero values to maintain reliable heartbeat functionality.

12-24: Verify timeout values for heartbeat reliabilityGiven the PR's objective to fix a bug causing premature termination of the heartbeat, it's crucial to ensure that the timeout values in
PingConfigare appropriate. While the implementation looks correct, consider reviewing and possibly adjusting the following:
- The default timeout value in
PingConfig(currently set to 30 seconds).- The usage of this timeout in the
to_active_pingfunction.Verify that these values provide enough time for the heartbeat to complete its cycle without premature termination, especially in scenarios with slower network conditions or when dealing with a large number of peers.
To assist in this verification, you can run the following script to check the current timeout values and their usage:

4-4: LGTM: Import addition for StreamExtThe addition of
StreamExtto the imports is appropriate and necessary for the changes made in theperform_heartbeat_roundmethod, specifically for using thecollectmethod on streams.
Line range hint
1-338: Summary of changes and final verificationThe modifications to the
perform_heartbeat_roundmethod effectively address the PR objectives by:
- Simplifying error handling, potentially fixing the premature termination issue.
- Enhancing logging to provide more detailed insights into the heartbeat process.
These changes should improve the reliability and observability of the heartbeat mechanism.
To ensure the changes fully resolve the issue described in #6536:
Let's verify that the heartbeat process now correctly handles outbound connections:
#!/bin/bash # Search for outbound connection handling in the heartbeat process rg --type rust 'outbound.*connection.*heartbeat|heartbeat.*outbound.*connection' transport/network/src/If this search doesn't yield relevant results, we may need to investigate how outbound connections are managed in relation to the heartbeat process.
179-186: Improved logging and simplified error handlingThe changes in this segment improve the heartbeat process in two ways:
The addition of
peers_contactedenhances logging by providing more context about the heartbeat round.Changing from
try_collecttocollectsimplifies error handling, which may address the premature termination issue mentioned in the PR objectives.However, we should verify that this change doesn't inadvertently ignore important errors.
To ensure we're not losing critical error information, let's check how errors were handled before this change:
✅ Verification successful
Error handling remains intentional with
collectThe usage of
collect::<Vec<_>>()in the heartbeat process continues to intentionally ignore ping errors, as indicated by the code comments:
- In the
Either::Rightbranch, the comment// We intentionally ignore any ping errors hereconfirms that error handling is as intended.Therefore, the simplified error handling does not inadvertently ignore important errors.

200-201: Improved logging and consistent mutability: LGTM!The changes enhance the
pingmethod in two ways:
- Adding
fields(peers.count = peers.len())to the tracing macro improves logging by including the count of peers being pinged. This will be helpful for monitoring and debugging the heartbeat functionality.- Changing the
peersparameter tomut peersaligns with the existing logic where the vector is modified. This ensures consistency and prevents potential compiler warnings.These improvements support the PR's objective of fixing the heartbeat bug by providing better insights into peer interactions.
