After the excrutiatingly entertaining consortium meeting/break day yesterday, we resumed this morning with a status meeting. The stackless group reported good progress, having compiled a working pypy-c with stackless support and implemented stack overflow detection for non-stackless builds. Unfortunately for the stackless builds, several CPOython tests expect infinite recursion to result in an error -- and do so fairly quickly, i.e. in less time than it takes to fill the entire heap with stack frames. This group's work is basically done for this sprint, although Anders and Christian are going to work on compliancy testing with the new pypy-c. While waiting for builds targeting compliancy tests, they are also going to investigate reorganizing code generation to improve locality. The ootype group is also progressing well. The RTyper has mostly been refactored to be independent of the targeted type system and work is continuing on implementing the new OOType type system alongside the existing LLType target. This group will be continuing, although with somehwat different membership -- Michael joining and half of each of Samuele and Arre leaving. Michael and Andrew's work on the PPC backend has progressed to the point where essentially any function that only manipulates integers can be translated (with an exceedingly stupid register allocator). Further work depends to a large extent on the llinterpreter work (see below) so this work will wait until after the sprint. Andrew is moving to work on implementing a Numeric-a-like for PyPy, together with Ludovic. The LLInterpreter grouplette (Carl and 0.5 Armins and a little Holger) did not produce much code since there are many decisions to be made and the implications of these decisions are not understood. A discussion group of Carl, Armin, Samuele, Holger, Christian and Arre will try to shine lights into these shadows, and report after lunch. Valentino and Amaury are going to implement the socket module. This is a step towards allowing Valentino to run Twisted on PyPy and thus make him very happy. This sprint is working in quite a different way to previous sprints -- there is lots of discussion which isn't new, but the farming off of discussion to groups of 5-6 people who present a report to the larger group is a novelty and seems to be working well (15+ people is too many for a focussed technical discussion). Another difference is a less strict emphasis on "pair" programming -- or, if you like, we are still pair programming but we have redefined "pair" to mean a group of two to six programmers :) Cheers, mwh & cfbolz -- Linux: Horse.
