Yesterday was another good day at the pre-EP sprint. We mostly started by polishing stuff from the day before -- unicode characters, pre-built caches. Holger and Michael removed by writing boring code a use of specialize:memo we weren't feeling intelligent enought to support in the rtyper. Armin and Anders made yet another pass through the list of partially supported 'builtins'[1] and made some decisions about whether support should be removed, finished or ignored for now. The we had bit of a planning session and decided that (Christian and Arre) and (Anders and Armin) would pair on supporting builtins and Holger, Samuele and Michael would work on translator issues. Holger and Michael implemented for the C translator the few remaining unsupported float operations the rtyper could emit. Arre and Christian implemented a few more operations on rdicts. Armin and Anders worked on the list of builtins in the usual fashion: sometimes removing code now deemed to be not rpython, sometimes by removing special-casing code that was no longer necessary and sometimes by adding code to the rtyper. Holger, Michael and Samuele attempted to translate demo/bpnn.py and fixed the problems they ran into; this included obscure behaviour when the rtyper hit code calling a statically known bound method of a Constant, the same when the Constant was of a class that was only seen by the RTyper as a class of such a Constant and not elsewhere. Holger and Armin refactored some of the rtyper code in the area of equality. Michael and Samuele fixed some broken code in the c translator in the area of calling C functions not implemented by us. Anders with help from Armin implemented is_true for PBC and fixed some bugs. Holger and Armin implemented yet another sort of dictionary: 'constant' dicts that are built at initialization time and only queried thereafter. Then we called it a day and went for dinner. Today, we plan to carry on the above and do a little planning for the post-EP sprint (which I won't be at, as I'll be involved in the much-more-entertaining task of moving house) and maybe, maybe, writing a talk for that conference we hear is happening quite soon.
