PyPy Göteborg Cleanup Sprint November 19 - November 25 2007 =========================================================== The next post-EU-project PyPy sprint will be in Gothenburg, Sweden. It will focus on cleaning up the PyPy codebase and making it ready for the next round of improvements. It is a "public" sprint but it will probably be more suitable for people already somewhat acquainted with PyPy. Topics and goals ---------------- Meta-Tasks ++++++++++ - Tracker-gardening - Start slowly thinking about 1.1 plans Translation toolchain +++++++++++++++++++++ - finish rctypes removal - move away from implicit keepalives - raw_malloc should be split, rffi one should not use obmalloc (it's not thread-safe) - kill simulator, run the semi space tests on llinterp (may happen before) - have a moving gc correct version of the gc framework transformation - delegate finding type stuff like vtables etc to GC, cleaner interface for rtti, simplify translator/c/gc.py - think about approaches to id, especially concerning boehm, where the id will keep the object alive and concerning a moving GC - clean up the tangle of including headers in the C backend - review pdbplus, especially the graph commands, also in the light of https://codespeak.net/issue/pypy-dev/issue303 and the fact that we can have more than one translator/annotator around (with the timeshifter) - Kill half concrete wrapper - Kill opaque hacks on the C backend - decide how to implement constants in rffi - think about/remove orphaned parts - finish ll2ctypes, especially rffi_platform Interpreter +++++++++++ - there's a shadow tracking bug it seems - fix the taint space - review the things implemented at applevel whether they are performance-critical JIT +++ - start writing real unit tests for the merging logic Location -------- The sprint will be held in the apartment of Laura Creighton and Jacob Hallén which is at Götabergsgatan 22 in Gothenburg, Sweden. Here is a map_. This is in central Gothenburg. It is between the tram_ stops of Vasaplatsen and Valand, where many lines call. .. _tram: http://www.vasttrafik.se .. _map: http://gulasidorna.eniro.se/query?stq=0&streetname=G%F6tabergsgatan+22%2C+G%F6teborg&what=map&asearch=1 Probably cheapest and not too far away is to book accomodation at `SGS Veckobostader`_.
