Log:
- gigantic intermediary checkpoint-checkin
this checkin is mainly for internal 'checkpointing' reasons
please don't look at it too closely until you want to participate
in the refactorings. it's definitely neccessary to cleanup
the refactored code although it's beginning to work ...
- trivial object space works with a more unified approach
to functions, code and wrapping app-level stuff into
interpreter-level code. StdObjSpace fails because multimethods
deeply depend on interpreter/pycode.py
depends deep
- moved some tests from appspace/test to interpreter/test where
they belonged (test_exec
stdspace and annspace fail miserably (don't even try them)
- got rid of 'extmodule' and builtin_*app* stuff
- revamped PyFrame initialization (now a 'ScopedCode' invokes
either 'setdictscope' or 'setfastscope' to set the local
scope of the frame. the frame doesn't invoke any analysis
itself anymore.
- introduced a 'ScopedCode' class which takes a space,
a cpython code object, global and closure scope. Currently you call
'eval_frame(w_locals)' to trigger interpretation of the interp-level defined
function.
- introduced an 'InterpretedFunction' which takes a space,
a function object, global and closure scope. Currently you call
'eval_frame(w_args, w_kwargs)' to trigger interpretation of the
interp-level defined function. The arguments are parsed with
another app-level function 'parse_args_complex' which is a
rewrite (50% code) of 'decode_code_arguments'
- introduced an 'AppVisibleModule' class that allows to easily
define builtin modules (which can access interp-level stuff).
See the doc-string for more info.
- all the previous new classes live live in 'interpreter/gateway.py'
which seems to be a good name to define stuff that 'connects'
interp-level and app-level execution.
- disabled 'mod' and 'divmod' complexobject-tests because they
fail in python-2.3 (which also issues deprecation warnings)
- improved the tool.test to skip non-importable modules (and
print a warning)
so much for now.
