Jakob,
This looks fairly correct. A few comments below.
Control Flow
============
The calling sequence is:
main() (in python.c) -> Py_Main() (main.c) -> PyRun_FooFlags() (pythonrun.c) ->
run_bar() (pythonrun.c) -> PyEval_EvalCode() (ceval.c) -> PyEval_EvalCodeEx()
(ceval.c) -> PyEval_EvalFrameEx() (ceval.c).
What this misses is the compiler stuff, i.e. PyParser_ASTFromFoo and
PyAST_Compile, which precedes the call to PyEval_ (atleast, no byte code
file is available).
Further, if I have my way with the AST optimization code, the symtable
construction will be an explicit step in between these >:)
In any case, this is awesome work Jakob. It'd be great for this stuff to
be documented in such detail -- I sure wish I had something like this to
go by when I first started hacking on the source -- but the details seem
to change quite often. Still, seeing the detail distilled once in a
while is sort of nice, and great for anybody looking to get their teeth
into the code.
Thanks for doing the hard yards. :)
Cheers,
T
