PROFILE
Halil Durmus
During December 2024, Durmus Halil enhanced native interoperability in the dart-lang/sdk repository by developing refWithFinalizer for StructPointer and UnionPointer within Dart FFI. This feature allows Dart views of native memory to be safely tied to the lifetime of underlying native resources, reducing memory leaks and use-after-free errors in interop scenarios. The work involved coordinated updates to the FFI verifier, mock SDK, transformer, and test suites, demonstrating proficiency in Dart, C++, and memory management. By focusing on API design and robust testing, Durmus delivered a well-integrated solution that improves reliability for projects leveraging Dart’s native interoperability features.

Dec 1, 2024December 2024: Focused on strengthening native interop safety in the dart-lang/sdk. Delivered a critical FFI enhancement: refWithFinalizer for StructPointer and UnionPointer, enabling Dart views of native memory tied to a finalizer. This work required coordinated updates across the FFI verifier, mock SDK, transformer, and tests to support the new functionality. The change enables safer memory management by aligning Dart-side memory views with the lifetime of native memory, reducing leaks and crashes in interop scenarios. There were no major bugs fixed this month; the effort prioritized safety and reliability of interop. Business value: reduces memory-related crashes and leaks in native interop; improves cross-language interoperability and reliability for projects using Dart FFI. Technologies/skills demonstrated include Dart FFI, memory management, API design, test and verifier integration, and cross-repo coordination.
