Revision as of 08:02, 25 June 2017

Improve stability, testing and bring modern C++ to KStars

Brief explanation: KStars has a mature codebase with well-written C++. It has been under constant development for the last 16 years and requires serious modernization due to the complexity of the code with its many contributors. The student is required to refactor the sources with modern C++11/C++14 features, explore and fix corner cases, perform static code analysis and implement new testing methods.

Expected results:

Refactor code to C++11/C++14 Replace raw pointers with smart pointers where appropriate. Use standard containers. Migrate all connections/slots to new Qt style connection. Add new unit and functional tests covering the complete scope of the source code. Reduced memory footprint especially on embedded devices. Knowledge Prerequisite: C++, Qt, Data Structures
