components/core/src/clp/TransactionManager.hpp (3)
6-15: LGTM: Well-structured class declaration with appropriate constraints.The namespace usage is consistent, and the class documentation clearly explains the purpose and template parameters. The
requiresclause effectively ensures that both handler types are invocable, which is a good use of C++20 features for type constraints.Consider adding a brief example usage in the class documentation to further clarify how the
TransactionManagershould be used.
18-35: LGTM: Well-implemented constructor and destructor with appropriate ownership semantics.The constructor correctly initializes the handler members, and deleting copy/move operations ensures unique ownership of the handlers. The destructor logic appropriately calls the correct handler based on the transaction state.
Consider marking the destructor as
noexcept(false)to indicate that it may throw exceptions, as the handlers might throw. This improves exception safety by allowing the program to terminate if an exception is thrown during stack unwinding:~TransactionManager() noexcept(false) { // ... existing implementation ... }
44-48: LGTM: Appropriate private members with correct initialization.The member variables are correctly declared as private, and the
m_successflag is initialized to false, which is consistent with the class documentation.For consistency with the class's move semantics, consider marking the handler members as
[[no_unique_address]]:[[no_unique_address]] SuccessHandler m_success_handler; [[no_unique_address]] FailureHandler m_failure_handler;This can potentially reduce the size of the class when the handlers are empty function objects.

483-483: LGTM! Consider adding a unit test file for TransactionManager.The addition of 'src/clp/TransactionManager.hpp' to the SOURCE_FILES_unitTest list is appropriate and aligns with the PR objective. This ensures that the newly extracted TransactionManager class will be compiled and linked with the unit tests.
Consider creating a dedicated unit test file (e.g., 'test-TransactionManager.cpp') to thoroughly test the functionality of the TransactionManager class. This would help ensure the reliability of this newly extracted helper class.

38-39: Address the TODO: Replace hard-coded version check withvalidate_protocol_versionThe TODO comment indicates that the hard-coded version check should be replaced with
ffi::ir_stream::validate_protocol_versionbefore the KV-pair IR format is formally released.Would you like assistance in implementing
validate_protocol_versionor opening a GitHub issue to track this task?

components/core/src/clp/TransactionManager.hpp (3)
1-5: LGTM: Proper include guards and necessary include statement.The include guards follow the expected naming convention, and the inclusion of <type_traits> is appropriate for the template metaprogramming used in this class.
38-41: LGTM: Simple and effectivemark_successmethod.The
mark_successmethod is straightforward and serves its purpose well. The use ofauto -> voidis consistent with modern C++ practices.
1-51: Excellent implementation of theTransactionManagerclass.The
TransactionManagerclass is well-designed and implemented, aligning perfectly with the PR objectives. It successfully extracts the transaction management logic into a standalone, reusable component. The use of templates and modern C++ features likerequiresclauses enhances its flexibility and type safety.The class effectively encapsulates the RAII-style management of success and failure handlers, providing a clear and easy-to-use interface. This implementation should indeed be beneficial to other parts of the codebase, as intended.
Overall, this is a high-quality addition to the project that enhances code reusability and maintainability.

16-16: LGTMThe inclusion of
"../../TransactionManager.hpp"correctly references the newly extractedTransactionManagerclass, promoting code reusability.

82-83: LGTM! Consider extracting the revert lambda for improved readability.The replacement of the
TransactionManagerobject with lambda functions simplifies the code and aligns with the PR objective. The use ofnoexceptlambdas is a good practice for exception safety.To further improve code readability, consider extracting the revert lambda into a named function:
+ auto revert_state = [&]() noexcept -> void { + m_utc_offset = utc_offset_snapshot; + m_schema_tree->revert(); + }; + TransactionManager revert_manager{ []() noexcept -> void {}, - [&]() noexcept -> void { - m_utc_offset = utc_offset_snapshot; - m_schema_tree->revert(); - } + revert_state };This change would make the
TransactionManagerconstruction more concise and improve the overall readability of the function.

Description
TransactionManageris introduced in #511 to perform an RAII-style success/failure management. It was added as a local helper class inside the deserializer implementation. This PR extracts it as a stand-alone general helper class for two reasons:Validation performed
