Tizen .NET Memory Profiler

In this paper we present a tool for identifying memory leaks in applications with mixed native and managed code. Such applications have parts with different memory management methods - the managed part is handled by the garbage collector, while the native part allocates and frees memory manually using OS-provided system calls. This presents a unique set of problems when trying to find a memory leak - the managed-unmanaged boundary makes it hard to identify when unmanaged memory is no longer needed in the managed code, and vice versa. Existing solutions tend to focus on one part or the other, however in order to fully understand application's behavior, a comprehensive tool is needed. We have built a memory profiler that is able to trace both managed and unmanaged memory allocations, and combine them into a comprehensive overvew of the application's memory, making managed, native, and unmanaged-from-managed memory leaks evident.
