We are happy to accept good ideas around the PyPy ecosystem. If you need more information about the ideas we propose for this year please join us on irc, channel #pypy (freenode). If you are unsure, but still think that you can make a valuable contribution to PyPy, dont hesitate to contact us on #pypy or on our mailing list. + + +* **Optimize PyPy Memory Usage**: PyPy currently emits a small executable file and a large shared object file. To reduce the base interpreter size we think it would be helpful to have several shared object files that can be dynamically loaded if the module is needed. There are several other potential places where we could improve. + +* **VMProf + memory profiler**: vmprof by now has a memory profiler that can be used already. We want extend it with more features and resolve some current limitations. + +* **VMProf visualisations**: vmprof just shows a flamgraph of the statistical profile and some more information about specific call sites. It would be very interesting to experiment with different information (such as memory, or even information generated by our jit compiler). + +* **Explicit typing in RPython**: PyPy wants to have better ways to specify the signature and class attribute types in RPython. See more information about this topic below on this page. + +* **Virtual Reality (VR) visualisations for vmprof**: This is a very open topic with lots of freedom to explore data visualisation for profiles. No VR hardware would be needed for this project. Either universities provide such hardware or in any other case we potentially can lend the VR hardware setup. + Simple tasks for newcomers -========================== +-------------------------- * Tkinter module missing support for threads: https://bitbucket.org/pypy/pypy/issue/1929/tkinter-broken-for-threaded-python-on-both @@ -15,9 +30,8 @@ https://bitbucket.org/pypy/pypy/issue/1942/support-for-af_xxx-sockets -================== Mid-to-large tasks -================== +------------------ Below is a list of projects that are interesting for potential contributors who are seriously interested in the PyPy project.
