parameters that contained both anonymous tuples and *arg or **arg. Ex:
def f(a, (b, c), *d): pass
Fix the symtable_params() to generate names in the right order for
co_varnames slot of code object. Consider *arg and **arg before the
"complex" names introduced by anonymous tuples.
module__doc__: Document the Warning subclass heirarchy.
make_class(): Added a "goto finally" so that if populate_methods()
fails, the return status will be -1 (failure) instead of 0 (success).
fini_exceptions(): When decref'ing the static pointers to the
exception classes, clear out their dictionaries too. This breaks a
cycle from class->dict->method->class and allows the classes with
unbound methods to be reclaimed. This plugs a large memory leak in a
common Py_Initialize()/dosomething/Py_Finalize() loop.
pythonrun.c: In Py_Finalize, don't reset the initialized flag until after
the exit funcs have run.
atexit.py: in _run_exitfuncs, mutate the list of pending calls in a
threadsafe way. This wasn't a contributor to bug 128475, it just burned
my eyeballs when looking at that bug.
symbol table for each top-level compilation unit. The information in
the symbol table allows the elimination of the later optimize() pass;
the bytecode generation emits the correct opcodes.
The current version passes the complete regression test, but may still
contain some bugs. It's a fairly substantial revision. The current
code adds an assert() and a test that may lead to a Py_FatalError().
I expect to remove these before 2.1 beta 1.
The symbol table (struct symtable) is described in comments in the
code.
The changes affects the several com_XXX() functions that were used to
emit LOAD_NAME and its ilk. The primary interface for this bytecode
is now com_addop_varname() which takes a kind and a name, where kind
is one of VAR_LOAD, VAR_STORE, or VAR_DELETE.
There are many other smaller changes:
- The name mangling code is no longer contained in ifdefs. There are
two functions that expose the mangling logical: com_mangle() and
symtable_mangle().
- The com_error() function can accept NULL for its first argument;
this is useful with is_constant_false() is called during symbol
table generation.
- The loop index names used by list comprehensions have been changed
from __1__ to [1], so that they can not be accessed by Python code.
- in com_funcdef(), com_argdefs() is now called before the body of the
function is compiled. This provides consistency with com_lambdef()
and symtable_funcdef().
- Helpers do_pad(), dump(), and DUMP() are added to aid in debugging
the compiler.
except that it always returns Unicode objects.
A new C API PyObject_Unicode() is also provided.
This closes patch #101664.

- Use PyObject_RichCompare*() where possible: when comparing
keyword arguments, in _PyEval_SliceIndex(), and of course in
cmp_outcome().
Unrelated stuff:
- Removed all trailing whitespace.
- Folded some long lines.
message, and tries to make the messages more consistent and helpful when
the wrong number of arguments or duplicate keyword arguments are supplied.
Comes with more tests for test_extcall.py and and an update to an error
message in test/output/test_pyexpat.
re-initializing Python (Py_Finalize() followed by Py_Initialize()) to
blow up quickly. With the DECREF removed I can't get it to fail any
more. (Except it still leaks, but that's probably a separate issue.)
