97-98: Consider usingPy_RETURN_NONEmacro directlyInstead of defining
get_new_ref_to_py_none(), you can directly use thePy_RETURN_NONEmacro where needed, simplifying the code.src/clp_ffi_py/ir/native/PyFourByteDeserializer.hpp (2)
14-16: Improved code clarity with static methods sectionAdding a comment to label the "Static methods" section enhances readability and organisation of the class.
38-40: Reordered member declarations for better structurePlacing
m_py_typebeforePyObject_HEADimproves the logical grouping of static and instance members, enhancing code structure.src/clp_ffi_py/ir/native/Metadata.cpp (1)

53-57: Consider enhancing error message specificity.While the error handling is correct, consider including the actual parsing error in the exception message to aid in debugging.

5-12: Appropriate inclusion of necessary headersThe added headers like
<concepts>,<string_view>, and others are essential for the features utilised in the code, such as concepts and string manipulations.
17-17: Correct inclusion of<clp/ir/types.hpp>Including
<clp/ir/types.hpp>is appropriate as it provides necessary type definitions used in the code.
21-21: Inclusion ofapi_decoration.hppfor API decorationAdding
<clp_ffi_py/api_decoration.hpp>ensures the availability ofCLP_FFI_PY_METHOD, which is used for method decoration.
Line range hint
71-93: Improved code organisation with forward declarationsForward declaring
handle_incomplete_ir_error,deserialize_log_events, andget_new_ref_to_py_noneenhances code readability by providing an overview of function signatures before their implementations.
87-93: Effective use of C++20 concepts in templated functionIntroducing the
TerminateHandlerSignatureconcept and templatingdeserialize_log_eventsenforces function signature constraints at compile-time, improving type safety.
Line range hint
115-191: Ensured proper loop termination indeserialize_log_eventsThe loop within
deserialize_log_eventshas appropriate exit conditions, handling both successful deserialization and error cases, thus preventing infinite loops. This aligns with the existing practice noted in previous implementations.
Line range hint
199-227: Robust error handling indeserialize_preambleThe
deserialize_preamblefunction correctly handles different error scenarios, including incomplete IR streams and unsupported encoding types, ensuring stability.
Line range hint
316-384: Proper handling of optional queries indeserialize_next_log_eventThe function effectively manages the optional
queryparameter, ensuring correct deserialization of log events whether a query is provided or not.src/clp_ffi_py/ir/native/deserialization_methods.hpp (3)
6-6: Inclusion ofapi_decoration.hppis necessaryIncluding
<clp_ffi_py/api_decoration.hpp>provides theCLP_FFI_PY_METHODmacro required for method decoration.
11-13: ApplyingCLP_FFI_PY_METHODmacro to function declarationsDecorating
deserialize_preamblewithCLP_FFI_PY_METHODensures proper linkage and symbol exportation.
14-15: Consistent application of API decorationAdding
CLP_FFI_PY_METHODtodeserialize_next_log_eventaligns it with other API methods, promoting consistency.src/clp_ffi_py/ir/native/PyFourByteDeserializer.hpp (3)
25-27: Prevented instantiation by deleting default constructorDeleting the default constructor ensures that
PyFourByteDeserializercannot be instantiated, aligning with its intended use as a namespace for static methods.
28-33: Disallowed copying and moving of the classBy deleting the copy and move constructors and assignment operators, the class is further protected from unintended use, reinforcing its static nature.
34-36: Explicit default destructor declaredDeclaring a default destructor maintains clarity and adheres to best practices, even though the class cannot be instantiated.

3-9: LGTM! Include directives are well-organized.The new includes are properly ordered and necessary for the functionality.
22-26: LGTM! Good use of safe JSON access methods.The implementation properly uses
.at()for bounds-checked access and includes appropriate documentation.

13-19: LGTM! Clear and informative documentation.The documentation string effectively communicates the purpose and usage constraints of the class.
72-79: LGTM! Well-structured type slot definitions.The implementation properly configures Python type slots with appropriate NOLINT directives.
src/clp_ffi_py/ir/native/PyMetadata.hpp (3)
20-49: LGTM! Well-documented static method declarations.The static methods are thoroughly documented with clear purpose, parameters, and return values.
50-61: LGTM! Good use of C++ special member functions.The explicit deletion of constructors and assignment operators properly enforces the intended usage pattern.
113-114: LGTM! Appropriate use of static member variable.The static member is properly declared inline and uses appropriate smart pointer type for Python object management.
src/clp_ffi_py/ir/native/PyMetadata.cpp (4)
196-201: LGTM! Complete control flow with Python macros.The implementation correctly uses
Py_RETURN_TRUEandPy_RETURN_FALSEmacros, which expand to return statements. The static analysis warning about missing returns is a false positive.🧰 Tools

118-119: LGTM! The additions align with the PR objectives.The new files added to the clang-tidy check list appropriately cover all the components mentioned in the PR objectives. This includes the deserialization methods, metadata handling, and Python type integration components.
Let's verify that we haven't missed any related files:
Also applies to: 123-124, 129-130, 135-136
✅ Verification successful
All relevant files are properly included in the clang-tidy checks
The verification confirms that all deserialization, metadata, and four-byte related files are correctly included in the lint-tasks.yml configuration. The implementation is thorough and no files are missing from the checks.
