240-264: Ensure thecampaignfunction is tested.No direct tests for the
campaignfunction were found in the codebase. It is crucial to add tests to verify the functionality and error handling of this function.
- Add unit tests or integration tests covering the
campaignfunction to ensure its reliability.Analysis chain
Keep-alive logic in
campaignlooks good.The modifications ensure the keep-alive operation is completed within the specified interval, and appropriate error handling is in place.
However, ensure that this function and its new logic are adequately tested.
Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify if the `campaign` function is tested. # Test: Search for tests related to the `campaign` function. Expect: Results indicating tests. rg --type rust -A 5 $'campaign'Length of output: 2114
Script:
#!/bin/bash # Description: Verify if the `campaign` function is tested. # Test: Search for test functions related to the `campaign` function, particularly in test directories or files. rg --type rust -A 5 'campaign' --glob '*test*'Length of output: 46
Script:
#!/bin/bash # Description: Broaden the search to verify if the `campaign` function is tested. # Test: Search for all references to the `campaign` function in the entire codebase. rg --type rust -A 5 'campaign'Length of output: 2114
300-342: No tests found for thekeep_alivefunction.The search did not yield any results indicating that the
keep_alivefunction is directly tested in the identified test files. It is recommended to add explicit tests to ensure the function's behavior is thoroughly validated.
- Review and add tests for the
keep_alivefunction to ensure it is adequately covered.Analysis chain
The
keep_alivefunction looks good.The function correctly handles the keep-alive logic and includes appropriate error handling and logging.
However, ensure that this function is adequately tested.

36-36: Increase inMETA_LEASE_SECSdurationThe
META_LEASE_SECSconstant has been increased from 3 to 5 seconds. This change affects the lease duration for themetasrvleader. Ensure that this adjustment aligns with the desired lease duration for the system.src/meta-srv/src/election/etcd.rs (2)
21-21: Approved: New imports for lease management and timeout handlingThe new imports
LeaderKey,LeaseKeepAliveStream,LeaseKeeper, andtimeoutare essential for the newkeep_alivemethod and enhanced error handling in thecampaignmethod.Also applies to: 26-26
238-253: Approved: Enhanced error handling with timeout incampaignmethodThe usage of
timeoutfor the keep-alive operation in thecampaignmethod ensures that the operation completes within the specified interval, which is crucial for maintaining leadership. The error handling is also enhanced.Verify that the
META_KEEP_ALIVE_INTERVAL_SECSvalue is appropriate for the desired keep-alive interval.src/meta-srv/src/metasrv.rs (1)
453-453: Approved: Change tocommon_runtime::spawn_writeThe change from
common_runtime::spawn_bgtocommon_runtime::spawn_writein thetry_startmethod impacts asynchronous operation handling. This adjustment is likely aimed at ensuring that the write operations are handled appropriately in the background.Verify that this change aligns with the desired behavior for asynchronous write operations.

21-22: Approved: New imports are necessary and used appropriately.The new imports (
LeaderKey,LeaseKeepAliveStream,LeaseKeeper, andtimeout) are essential for thekeep_alivemethod.Also applies to: 26-26
235-271: Ensure proper error handling for timeout.The timeout for the
keep_aliveoperation ensures it completes withinMETA_KEEP_ALIVE_INTERVAL_SECS. The error handling seems appropriate, but consider logging additional context for debugging purposes.
I hereby agree to the terms of the GreptimeDB CLA.
