Ah. I suspected that, but didn't understand the subprocess code enough
to figure that out. Thanks.
Here is my real problem. I used to just pass a regular dictionary to
code.InteractiveInterpreter, which worked well enough. But I just
discovered an issue with pickling in the PyCrust shell, illustrated
below:
Welcome To PyCrust 0.8 - The Flakiest Python Shell
Sponsored by Orbtech - Your source for Python programming expertise.
Python 2.2.2 (#1, Oct 28 2002, 17:22:19)
[GCC 3.2 (Mandrake Linux 9.0 3.2-1mdk)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>> def foo():
... pass
...
>>> pickle.dumps(foo)
Traceback (most recent call last):
File "<input>", line 1, in ?
File "/usr/local/lib/python2.2/pickle.py", line 978, in dumps
Pickler(file, bin).dump(object)
File "/usr/local/lib/python2.2/pickle.py", line 115, in dump
self.save(object)
File "/usr/local/lib/python2.2/pickle.py", line 225, in save
f(self, object)
File "/usr/local/lib/python2.2/pickle.py", line 519, in save_global
raise PicklingError(
PicklingError: Can't pickle <function foo at 0x8654b9c>: it's not found
as __main__.foo
>>>
So I decided to switch to using sys.modules['__main__'].__dict__, which
eliminated the pickling error, but introduced a bunch of clutter in the
local namespace. Any suggestions?
