PyPy cleanup areas

This is a todo list that lists various areas of PyPy that should be cleaned up (for whatever reason: less mess, less code duplication, etc).

translation toolchain

  • low level backends should share more code
  • all backends should have more consistent interfaces
  • geninterp is a hack
  • keepalives need to die, finally
  • change weakrefs to work together with the GC
  • delegate finding type stuff like vtables etc to GC
  • clean up the tangle of how the various mallocs are implemented and responsability distributed acrosss headers, policies, backends, and the gctransfomers, which varies depending on the GC :(, exploit better the removal of zeroing assumption
  • clean up the tangle of including headers in the C backend
  • make approach for loading modules more sane, mixedmodule capture too many platform dependecies especially for pypy-cli
  • 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)

interpreter

  • review the things implemented at applevel whether they are performance- critical
