16-26: Consider a more descriptive name for the exception class.
WhileOperationFailedis functional, a more domain-specific name (e.g.UnsupportedOperation) may help clarify its intended usage and differentiate it from general operation failures.
39-42: Follow up on the TODO for the move constructor and assignment operators.
You have a TODO indicating these could be defaulted once the base class has been updated. Ensure there is a tracked task or issue to revisit them.components/core/tests/test-StreamingCompression.cpp (1)
137-137: No call todecompress_and_compare.
Currently, you instantiate the LZMA decompressor but do not invokedecompress_and_compare. If full testing is planned, consider adding calls to verify the behaviour of the LZMA decompressor once implemented.

43-67: Confirm the non-implementation of ReaderInterface methods.
All these methods returnErrorCode_Unsupported, which is valid for now. However, please confirm if this is the final intended behaviour or if you plan to implement actual read and position control functionality in future.components/core/src/clp/streaming_compression/lzma/Decompressor.cpp (1)
9-16: Placeholder for read operations.
Thetry_readimplementation is returningErrorCode_Unsupported. This is fine as a placeholder, but remember to provide an actual LZMA-compatible read implementation if you intend to handle partial reads.components/core/tests/test-StreamingCompression.cpp (1)
21-21: Good inclusion of the new LZMA Decompressor header.
This inclusion ensures the LZMA decompressor can be instantiated and tested.components/core/CMakeLists.txt (1)
543-544: LGTM! The new LZMA decompressor files are properly integrated.The files are correctly added to the
SOURCE_FILES_unitTestvariable and are grouped with other compression-related source files.Let's verify the LZMA library configuration:
✅ Verification successful
Verified: LZMA decompressor files are correctly placed and configured
- LZMA library is properly configured with version, location, and include directory checks
- New decompressor files follow the project's structure, matching other compression implementations:
- components/core/src/clp/streaming_compression/lzma/Decompressor.cpp
- components/core/src/clp/streaming_compression/lzma/Decompressor.hpp

🧹 Nitpick comments (4)
components/core/src/clp/streaming_compression/lzma/Decompressor.cpp (1)
18-20: Consider adding TODO comments for future implementation.All methods are currently stubs that either return
ErrorCode_Unsupportedor throwOperationFailed. While this is acceptable for an initial interface, adding TODO comments would help track which methods need implementation.Add TODO comments to each method, for example:
auto Decompressor::try_read( [[maybe_unused]] char* buf, [[maybe_unused]] size_t num_bytes_to_read, [[maybe_unused]] size_t& num_bytes_read ) -> ErrorCode { + // TODO: Implement LZMA decompression logic return ErrorCode_Unsupported; }Also applies to: 22-24, 26-31, 33-38, 40-42, 44-50
components/core/src/clp/streaming_compression/lzma/Decompressor.hpp (3)
35-41: Consider documenting rationale for deleted move operations.The TODO comment explains that move operations will be defaulted when the base class is updated. Consider documenting why move operations are currently deleted to help future maintainers.
Add a comment explaining the rationale:
// Delete move constructor and assignment operator -// TODO: Change to default when the base decompressor class has been updated. +// TODO: Change to default when the base decompressor class has been updated +// Move operations are currently deleted because the base class does not support them Decompressor(Decompressor&&) noexcept = delete; auto operator=(Decompressor&&) noexcept -> Decompressor& = delete;
44-67: Improve documentation consistency.The documentation style should be consistent across all methods. Some improvements needed:
- Add periods at the end of parameter descriptions
- Use "Returns" for output parameters
- Add periods at the end of return value descriptions
Apply these changes to the documentation:
/** * Tries to read up to a given number of bytes from the decompressor. - * @param buf + * @param buf The buffer to read into. * @param num_bytes_to_read The number of bytes to try reading. - * @param num_bytes_read Returns the actual number of bytes read. + * @param num_bytes_read Returns the actual number of bytes read. - * @return ErrorCode_Unsupported + * @return ErrorCode_Unsupported. */
85-88: Add complete method documentation.The
close()method lacks a proper description of its purpose and behaviour.Add complete documentation:
-/* +/** + * Closes the decompressor and releases any resources. * @throw clp::streaming_compression::lzma::Decompressor::OperationFailed if unsupported. */

10-16: LGTM! Method signature and implementation are correct.The implementation correctly returns
ErrorCode_Unsupportedas a placeholder. The use of[[maybe_unused]]for parameters is appropriate since they are not used in the current implementation.components/core/src/clp/streaming_compression/lzma/Decompressor.hpp (1)
16-26: LGTM! Inner exception class is well-defined.The
OperationFailedexception class correctly extendsTraceableExceptionand provides a clear error message. The use of[[nodiscard]]andnoexceptis appropriate.
