Introduction
Greetings and welcome to my humble wiki abode.
My name is Ryan and I'm currently enrolled at DigiPen Institute of Technology - Singapore, earning a BSc in Real-Time Interactive Simulations course.
Project
Estimated Timeline
May
- Get a better feel of how the Wesnoth developers work.
- Study WML's technical implementation (learn how documents are parsed).
- Profile WML's memory usage and identify areas which are taking up large amounts of memory.
- Research on various implementations to reduce memory usage.
- Run ideas through developers and community for optimal solutions and refine them.
June
- Implement initial solutions and test, test, test.
- Research other possible areas of improvement.
July
- Research stops and working time should all be spent on continued implementation of discussed and agreed-upon solutions (no more new stuff).
- Prepare for mid-term evaluation.
August
- Testing and bug fixing
- Wrap up for final evaluation.
Technical Details
Currently, one of the major memory hogs is the use of std::map and the large amounts of strings stored by the config class.
The idea would be to find an efficient implementation to replace the usage of a map, reduce string duplicates and, if needed, revert to simpler data structures. Here are several ideas for implementation:
- Use a simple hash (with caching and fast reverse-hashing features) as the key instead of std::string.
- Store values in their integral forms instead of std::string.
- Find a viable replacement for std::map, like an ordered vector which indexes into values.
Time would also have to be allocated to study WML's technical implementation and possibly detail it in a technical document as I understand the documentation is lacking at the moment. There will probably be other areas for improvement as well, like lazy-loading, but those will have to wait until I fully understand the inner-workings of WML.
Expectations
Working on an OSS project for the first time, I expect to gain valuable industry skills/knowledge and to learn from the experienced developers currently on the Wesnoth project. This experience will also provide me a chance to work in a highly diversified team and learn to manage working with developers in different locations and timezones.
Wesnoth is a fun little game that I can see myself dedicating time and energy to developing even after GSoC is concluded. Plus, I wouldn't pass up on the chance to continue learning from the Wesnoth developers and expand my programming knowledge :)
