Rough preparation draft for saturday-afternoon 20051015 meeting Paris  

work group/pairing status 

- ootypes / rtyper refactoring: 
  Boris reports: continued to refactor rypting into 
  non-ll specific and ll-specific parts.  still a lot 
  of work to be done (currently you can specialize 
  an empty class with the oo-type system). 
  bert: squeak backend uses the oo-type system and 
  creates squeak class definitions. (oo-types are
  built manually there at the moment). 
- socket module: 
  all the interface is wrapped/implemented at interpreter-level 
  and is reusing the underlying (cpython) socket module.  There is 
  not translation/external function calls yet (which will introduce 
  platform issues).  
- numeric module: 
  started the basic Array type, you can construct such types that 
  contain floats or integers, and you can have efficient slices 
  (reusing the same underlying array).  The base Array class 
  is not connected to storage, subclasses are (specific to floats/ints). 
- l3interpreter: 
  have a refined very-low-level flow graph model, and we can 
  pass in integers and do addition. also the l3intepreter 
  is translateable and passes tests.  
- compiler issues
  ran the core compliancy tests (failing ones are mostly 
  due to missing weakref support).  problem is that we 
  are having a mix of all slightly incorrect compiler 
  (or at least don't know if they/which are correct) 
  variations.  It seems to make more sense to contribute the
  whole astcompiler rather than trying to come up with patches
  to the CPython version. 
- translation issues: 
  compliance tests start to run on pypy-c ( 
  but there are likely more bugs/issues lurking. 
  christian is working on locality of references by 
  analysing flowgraphs. 

pypy technical task planning 

Identify tasks to be done in between sprints, start with 
see paris-2005-possible-tasks.txt:
- full compiler/parser integration  

- pypy-sync meetings should constantly track/amend/modify those 
  technical tasks and in general focus on technical issues 
  NOTE though: pypy-sync cannot focus too much on EU requirements 
  because it's a more open/community forum. 

- idea is to collect all larger tasks and bring plannings 
  to the pypy-sync meetings.  Carl is going to do the next 
  pypy-sync meeting.  Send plans/larger task plannings to
  the moderators and don't wait until the moderator generates
  the idea himself.

EU-related Workpackage planning phase 2 

- WP09 and WP10 done and coordinated by logilab/dfki 
  people.  they should update the rest of us regarding 
  planning and also communicate regarding 
  possible related sprint topics. 

- WP02 dev infrastructure is merlinux responsibility, 
  should also suggest sprint topics (considering e.g. 
  a py lib sprint at PyCon ...) 

- other WPs in phase 2 are probably more generally in 
  common responsibility (like WP04/WP05) with the lead 
  partner taking special responsibility (towards the EU): 

  - WP03 (HHU) synchronisation CPython 
  - WP06 (HHU) core optimisations 
  - WP07 (tismerysoft) translator optimisations 
  - WP08 (Strakt) dynamic optimisations 
  - WP14 (Changemaker) dissemination/project representation 


  - WP05: left over work for Impara (when they get accepted)?
