Outside diff range and nitpick comments (46)
include/pika_hyperloglog.h (1)
34-56: LGTM! Consider adding a comment for empty methods.The new
PKHyperloglogSetCmdclass is well-structured and follows the pattern of other command classes in the file. The implementation looks correct and complete.Consider adding a brief comment for the empty
Split()andMerge()methods to explain why they are intentionally left empty. This can improve code readability and prevent future confusion. For example:// Split operation is not applicable for this command void Split(const HintKeys& hint_keys) override {} // Merge operation is not needed for this command void Merge() override {}include/pika_cache.h (1)
176-176: LGTM: New method ZSetAtIfKeyExists addedThe addition of the
ZSetAtIfKeyExistsmethod to thePikaCacheclass looks good. It extends the functionality for handling sorted sets (ZSet) operations.Consider adding a brief comment above the method declaration to explain its purpose and any important details about its behavior. For example:
// Performs a "set at" operation on a sorted set if the key exists. // Returns the status of the operation. rocksdb::Status ZSetAtIfKeyExists(std::string& key, std::string& member, PKZSetAtCmd* cmd, const std::shared_ptr<DB>& db);include/pika_command.h (1)
123-123: Consider adding overall documentation for new Pika-specific commands.The addition of these four new Pika-specific command constants (
kCmdNamePKHSetAt,kCmdNamePKZSetAt,kCmdNamePKSAdd,kCmdNamePKHyperloglogSet) is consistent with the existing code style and naming conventions. However, to improve maintainability and ease of use for other developers, consider adding a section in the file or in the project documentation that explains:
- The purpose of these Pika-specific commands.
- How they differ from their standard Redis counterparts.
- Any specific use cases or scenarios where these commands should be used.
This documentation will help future developers understand the rationale behind these custom commands and how to use them effectively.

187-192: LGTM! Consider initializingts_ms_in the constructor.The addition of
ToRedisProtocol()method andts_ms_member variable enhances the functionality and Redis protocol compatibility of theDecrCmdclass.Consider initializing
ts_ms_in the constructor instead of in the class definition. This allows for more flexibility in initialization and follows the general C++ best practice of initializing members in the constructor. For example:class DecrCmd : public Cmd { public: DecrCmd(const std::string& name, int arity, uint32_t flag) : Cmd(name, arity, flag, static_cast<uint32_t>(AclCategory::STRING)), ts_ms_(0) {} // ... rest of the class definition ... private: uint64_t ts_ms_; };
212-217: LGTM! Consider applying the same constructor initialization as suggested forDecrCmd.The changes to
DecrbyCmdare consistent with those made toDecrCmd, which is good for maintainability. The addition ofToRedisProtocol()method andts_ms_member variable enhances the functionality and Redis protocol compatibility of theDecrbyCmdclass.Please refer to the comment on
DecrCmdregarding initializingts_ms_in the constructor. Apply the same pattern here for consistency across similar classes.
Line range hint
1-1161: Overall, the changes enhance Redis compatibility and consistency across command classes.The modifications to
DecrCmd,DecrbyCmd, andAppendCmdclasses improve Redis protocol compatibility and potentially enhance timestamp handling. The consistency in these changes across similar classes is commendable.To further improve the code:
- Consider creating a base class for commands that require Redis protocol serialization and timestamp handling. This could reduce code duplication and improve maintainability.
- Ensure that the
DoInitial()method is consistently implemented across all command classes that require it.- Document the purpose and usage of the
ts_ms_variable, especially its role in Redis protocol serialization or any time-based operations.Next steps:
- Address the nitpicks about initializing
ts_ms_in constructors.- Provide more information about the
DoInitial()method inAppendCmd.- Consider refactoring to introduce a base class for common Redis protocol and timestamp functionality.

1-1000: Consider refactoring the test suite for improved maintainability and reliabilityWhile the test coverage appears comprehensive, there are several areas where the test suite could be improved:
Excessive use of
time.Sleep(): These make tests slower and potentially flaky. Consider using polling with timeouts or other synchronization mechanisms.Hardcoded error messages: Error message assertions like
Expect(slaveWrite.Err()).To(MatchError("ERR READONLY You can't write against a read only replica."))can be fragile. Consider using more flexible matching or focusing on error types rather than exact messages.Test suite length: The test suite is quite long, which can make it hard to maintain. Consider breaking it into smaller, more focused test files.
Repeated setup and teardown: There's repeated code for setting up and tearing down tests. Consider using BeforeEach and AfterEach hooks more extensively to reduce duplication.
Here's an example of how you might refactor the sleep statements:
func eventuallyEqual(ctx context.Context, masterClient, slaveClient *redis.Client, key string) { Eventually(func() string { return slaveClient.Get(ctx, key).Val() }, "10s", "100ms").Should(Equal(masterClient.Get(ctx, key).Val())) } // Use it like this: clientMaster.Set(ctx, "key", "value", 0) eventuallyEqual(ctx, clientMaster, clientSlave, "key")This approach is more reliable and often faster than using sleep statements.
src/pika_slot_command.cc (2)
723-724: Consider the purpose of introduced timestamp variables.Two unused
uint64_t ts_ms;variables have been introduced in theAddSlotKeyfunction. These variables appear to be intended for timestamp-related functionality, possibly for tracking when keys are added to slots and tags.To improve code clarity and maintainability:
If these variables are part of an ongoing implementation:
- Add TODO comments explaining their intended use.
- Create a ticket or issue to track the completion of this feature.
If these variables are no longer needed:
- Remove them to keep the code clean.
If you decide to implement the timestamp functionality:
- Ensure that the timestamps are consistently used for both slot and tag operations.
- Consider adding this information to the function's documentation.
- Update any related functions or methods that might need to handle or propagate this timestamp information.
Please clarify the intended use of these variables and update the code accordingly.
Also applies to: 734-735
Line range hint
1-1024: Summary of changes and recommendationsThe main changes in this file involve the introduction of two unused
uint64_t ts_ms;variables in theAddSlotKeyfunction. These variables appear to be intended for timestamp-related functionality but are currently not utilized.Recommendations:
- Clarify the purpose of these timestamp variables.
- Either implement the intended functionality or remove the unused variables.
- If part of an ongoing implementation, add appropriate TODO comments and create a tracking issue.
- Review any related functions or methods that might need to be updated if timestamp functionality is implemented.
Addressing these points will improve code clarity, maintainability, and prevent potential confusion for other developers working on this codebase.

277-278: LGTM! Consider adding a comment for clarity.The addition of the
ts_msparameter and its initialization look good. This change allows for timestamp tracking in theDecrbyoperation.Consider adding a brief comment explaining the purpose of the
ts_msparameter for better code readability:Status Redis::Decrby(const Slice& key, int64_t value, int64_t* ret, uint64_t* ts_ms) { + // Initialize timestamp to 0 *ts_ms = 0;tests/integration/zset_test.go (7)
Line range hint
1074-1088: Consider enhancing the ZCard test with edge cases.While this test covers the basic functionality of ZCard, it could be improved by including additional scenarios:
- Test ZCard on an empty set (should return 0).
- Test ZCard after removing all members from a set.
- Test ZCard with a large number of members to ensure it scales correctly.
These additions would provide more comprehensive coverage of the ZCard functionality.
Line range hint
1090-1118: Separate ZLexCount into its own test case.The current test mixes ZCount and ZLexCount functionalities, which test different aspects of sorted sets. To improve clarity and maintainability:
- Keep the existing ZCount tests as they are.
- Create a separate test case for ZLexCount with appropriate lexicographical ranges.
This separation will make the tests more focused and easier to understand. Additionally, consider adding more test cases for ZLexCount to cover various lexicographical ranges.
Line range hint
1148-1186: Consider testing different Aggregate functions in ZInterStore.The current test for ZInterStore is good, but it could be more comprehensive. Suggest enhancing it by:
- Testing different Aggregate functions (SUM, MIN, MAX) in the ZStore struct.
- Verifying the results for each Aggregate function to ensure they're calculated correctly.
- Testing with more than two input sorted sets to ensure it works with multiple sets.
These additions would provide more thorough coverage of the ZInterStore functionality and its various options.
Line range hint
1188-1251: Move the invalid command check to a separate test.The ZPopMax test is well-structured and comprehensive for testing the main functionality. However, the check for an invalid command at the end (line 1250) seems out of place in this test. Suggest:
- Moving the invalid command check to a separate test case.
- Naming the new test case something like "should handle invalid ZPOPMAX arguments".
This separation will make the tests more focused and easier to maintain. Each test should ideally check one specific behavior or edge case.
Line range hint
1253-1316: Refactor ZPopMin test similar to ZPopMax.The ZPopMin test is well-structured but has the same issue as the ZPopMax test. To improve consistency and maintainability:
- Move the invalid command check (line 1315) to a separate test case.
- Name the new test case "should handle invalid ZPOPMIN arguments".
- Consider combining the invalid argument tests for ZPOPMAX and ZPOPMIN into a single test case that checks invalid arguments for both commands.
This refactoring will make the tests more focused and consistent with the suggested changes for the ZPopMax test.
Line range hint
1-1316: Address commented-out tests throughout the file.There are numerous commented-out tests throughout this file. This practice can lead to confusion and maintenance issues. To improve the test suite:
- Review each commented-out test and determine if it's still relevant.
- For relevant tests, uncomment and update them to work with the current codebase.
- For obsolete tests, remove them entirely.
- If tests are commented out due to known issues or pending features, add a TODO comment explaining why they're disabled and what needs to be done to re-enable them.
Cleaning up these commented-out tests will improve the overall maintainability and clarity of the test suite.
Line range hint
1-1316: Overall assessment: Comprehensive test suite with room for improvementThis test file provides extensive coverage of Redis Zset operations. However, there are several areas for improvement:
- Reconsider the use of
PDescribeinstead ofDescribe, as it may unintentionally skip tests.- Enhance some tests with additional edge cases and scenarios (e.g., ZCard, ZInterStore).
- Refactor tests that mix different functionalities (e.g., ZCount and ZLexCount).
- Move invalid command checks to separate, focused test cases.
- Address the numerous commented-out tests throughout the file.
- Consider adding more comprehensive tests for complex operations like ZUnionStore and ZInterStore.
Implementing these suggestions will result in a more robust, maintainable, and clear test suite for Redis Zset operations.

64-65: LGTM! Consider adding a comment for the new parameter.The changes look good. The new
ts_msparameter allows returning the timestamp of the last modification, which is useful for tracking set changes.A minor suggestion:
Consider adding a brief comment explaining the purpose of the
ts_msparameter in the function signature or at the initialization point. This would improve code readability and maintainability.-Status Redis::SAdd(const Slice& key, const std::vector<std::string>& members, int32_t* ret, uint64_t& ts_ms) { - ts_ms = 0; +Status Redis::SAdd(const Slice& key, const std::vector<std::string>& members, int32_t* ret, uint64_t& ts_ms) { + // ts_ms will store the timestamp of the last modification + ts_ms = 0;Also applies to: 110-110

1-1984: General observations on the test suiteWhile reviewing this file, I noticed several points that might be worth addressing:
There are multiple commented-out test cases, particularly for commands not supported by Codis (e.g.,
SMove,SDiff,SInter). Consider either implementing these tests with Codis-specific behavior or removing them to keep the test suite clean.Several TODOs and references to GitHub issues are present throughout the file. It might be beneficial to create a tracking issue to address these over time.
The test coverage appears comprehensive for supported commands, which is commendable.
Would you like me to create a GitHub issue to track the cleanup and implementation of the commented-out tests?

1-1161: Summary of changes: Focused updates to HIncrby and HIncrbyfloat testsThe modifications in this file are consistently applied to the
HIncrbyandHIncrbyfloattest cases, adding anullptrparameter to each function call. These changes align with the PR objective of achieving idempotency and master-slave consistency. The focused nature of the updates, limited to these two functions, minimizes the risk of introducing unintended side effects in other parts of the test suite.To ensure comprehensive coverage of the changes, consider the following:
- Verify that no other hash-related functions require similar modifications for idempotency and master-slave consistency.
- Update the test documentation or comments to explain the purpose of the new
nullptrparameter, if not already done in the main implementation.- Consider adding new test cases that specifically target the idempotency and master-slave consistency aspects of these operations, if not covered elsewhere.

88-3795: Comprehensive test cases for PKScanRange and PKRScanRange.The test cases for PKScanRange and PKRScanRange are extensive and cover various scenarios. However, there are a few points to consider:
- The tests are quite long and could benefit from being split into smaller, more focused test cases.
- Some of the test logic is repeated across different groups. Consider extracting common setup and verification code into helper functions.
- The use of sleep(2) and db.Compact(DataType::kAll, true) after each group of tests might slow down the test suite. Consider if this is necessary for every test group.
Consider refactoring these test cases to improve readability and maintainability:
- Split the large test cases into smaller, more focused ones.
- Extract common setup and verification code into helper functions.
- Evaluate the necessity of sleep and compact operations after each test group.
Line range hint
3797-4230: Comprehensive test cases for PKPatternMatchDel.The PKPatternMatchDel test cases are well-structured and cover various scenarios. However, similar to the previous test cases, they could benefit from some refactoring:
- There's a lot of repetitive code for setting up the test data. Consider creating helper functions to set up the test data for each data type.
- The deletion and verification logic is repeated across test groups. This could be extracted into a helper function.
Consider refactoring these test cases to reduce code duplication:
- Create helper functions for setting up test data for each data type (String, Hash, Set, List, ZSet).
- Extract the common deletion and verification logic into a helper function.
Line range hint
4232-4619: Well-structured test cases for Expire, Del, Exists, Expireat, Persist, and TTL.These test cases are generally well-structured and cover the basic functionality of each operation. However, there are a few points to consider:
- Some test cases, like ExpireTest, could benefit from more edge case testing (e.g., expiring already expired keys, setting very large expiration times).
- The DelTest only tests deleting a single key. Consider adding tests for deleting multiple keys and non-existent keys.
- The ExistsTest is very basic. Consider adding more comprehensive tests, including checking for non-existent keys and multiple keys.
Enhance these test cases by:
- Adding more edge cases to the ExpireTest.
- Expanding the DelTest to cover multiple keys and non-existent keys.
- Enhancing the ExistsTest with more comprehensive scenarios.

82-83: Clarify the use of 'RAW_ARGS_LEN' incontent.reserveIn
PfMergeCmd::ToRedisProtocol(), you callcontent.reserve(RAW_ARGS_LEN);but it's unclear whetherRAW_ARGS_LENaccurately represents the required capacity. This could lead to inefficient memory allocation ifRAW_ARGS_LENdoesn't match the actual content size.Consider calculating the required size based on the actual content to be appended or provide a comment explaining the choice of
RAW_ARGS_LEN.include/wal_edit.h (1)
133-170: Consider documenting thread-safety requirements more prominentlyWhile there is a comment indicating that
WalSetis not thread-safe and requires external synchronization, consider enhancing the documentation to make this requirement more prominent. This can help prevent misuse of the class in multithreaded contexts.include/pika_set.h (2)
41-64: Add documentation for the newPKSAddCmdclassThe
PKSAddCmdclass is introduced without any explanatory comments. Please add documentation to describe the purpose of this class, how it differs fromSAddCmd, and any specific behaviors it implements. This will improve code readability and assist future maintainers.
52-52: Remove or clarify the commented-outDoUpdateCache()methodThe
DoUpdateCache()method is commented out in thePKSAddCmdclass. If this method is not needed, consider removing it to keep the code clean. If it's intended for future use, add aTODOcomment explaining the pending implementation.src/storage/src/redis.h (1)
292-293: Reassess the necessity of passingkey_foundby referenceIn the
ZIncrbymethod, the parameterbool& key_foundis passed by reference. Sinceboolis a small and simple type, passing by value might be more appropriate unless the method needs to modify the variable outside its scope. Verify if passing by reference is required in this context.src/pika_zset.cc (5)

173-183: Fix incorrect error handling by referencing the correct status variables.In the
ZIncrbyCmd::Do()method, the error handling incorrectly referencess_instead of the local status variables, which holds the result of theZIncrbyoperation. This could lead to improper error reporting and handling.Apply this diff to correct the error handling:
void ZIncrbyCmd::Do() { double score = 0.0; rocksdb::Status s = db_->storage()->ZIncrby(key_, member_, by_, &score, &ts_ms_, &key_found_); if (s.ok()) { score_ = score; char buf[32]; int64_t len = pstd::d2string(buf, sizeof(buf), score); res_.AppendStringLen(len); res_.AppendContent(buf); AddSlotKey("z", key_, db_); - } else if (s_.IsInvalidArgument()) { + } else if (s.IsInvalidArgument()) { res_.SetRes(CmdRes::kMultiKey); - } else { - res_.SetRes(CmdRes::kErrOther, s_.ToString()); + } else { + res_.SetRes(CmdRes::kErrOther, s.ToString()); } }

1674-1707: Type inconsistency: useint64_tforcount_instead ofunsigned intinZPopmaxCmd.In
ZPopmaxCmd::DoInitial(), the variablecount_is being assigned usingpstd::string2int, which outputs anint64_t. However,count_is declared asunsigned int, leading to potential type mismatch and incorrect behavior with negative values.Apply this diff to correct the type:
- unsigned int count_; + int64_t count_; void ZPopmaxCmd::DoInitial() { // existing code if (argv_.size() == 3) { - if (pstd::string2int(argv_[2].data(), argv_[2].size(), static_cast<int64_t *>(&count_)) == 0) { + if (pstd::string2int(argv_[2].data(), argv_[2].size(), &count_) == 0) { res_.SetRes(CmdRes::kInvalidInt); } } }This ensures proper handling of the count value and prevents unexpected behavior.

212-212: Approve: Good practice for pointer safetyThis change is a positive addition to the code. Setting
in_conntonullptrat the end of each iteration in the event processing loop is a good defensive programming practice. It ensures that:
- There's no risk of accidentally using a stale connection pointer in subsequent iterations.
- It makes the code more robust against potential future modifications that might inadvertently use
in_connoutside its intended scope.- It clearly signifies the end of the connection's lifecycle within the current iteration.
This change enhances the overall safety and clarity of the code without introducing any noticeable performance overhead.
