GSoC Project Ideas for 2013

Here are some ideas of possible 2013 summer project ideas for Mercurial. Your own ideas are welcome. You may decide to work on these ideas or use them as a starting point for your own. Either way, come talk to us in #mercurial in Freenode or on the mailing list.

1. Advanced revset optimization

topic:Revsets are a powerful built-in query language for looking at changesets. We even have an optimizing engine to reorder queries for performance. But there are several areas where things could be improved:

2. Unicode filename support on Windows

While Mercurial users on Linux and Mac can happily exchange repositories with filenames in Unicode and even legacy encodings, Windows presents some extra challenges for using non-ASCII filenames portably. We'd like to address this by introducing an automatic UTF-8 translation layer on Windows systems.

See WindowsUTF8Plan

3. Generic templating support

Mercurial has a powerful templating engine, but on the command line it's only available for log-like commands. We'd like to extend its power and flexibility to the rest of Mercurial's command-line interface, in addition to adding built-in support for standard formats like XML, JSON, etc.

See GenericTemplatingPlan

4. Improved built-in help

Mercurial's built-in help is quite good, but could be better. Here are some things that could be done:

5. Advanced Hgweb support

Our web interface is very handy, but there are a number of features that could be improved:

6. Performance tuning

Mercurial is fast but could always be faster. Possible areas include:

7. C implementation of command server API

See CommandServer.

8. Improvement of record API and User Interface

To be expended

9. Improvement of the testing tool and testing annotation

To be expended

10. obsolescence support in graphlog and hgweb

Thiis about displaying relation from ChangesetEvolution in graphlog (to be expended)
