[Python-Dev] Inconsistent behaviour in import/zipimport hooks

[Osvaldo Santana Neto]

Hi,

I'm working on Python[1] port for Maemo Platform[2] and I've found a
inconsistent behavior in zipimport and import hook with '.pyc' and
'.pyo' files. The shell section below show this problem using a
'module_c.pyc', 'module_o.pyo' and 'modules.zip' (with module_c and
module_o inside):

$ ls
module_c.pyc  module_o.pyo  modules.zip

$ python
>>> import module_c
>>> import module_o
ImportError: No module named module_o

$ python -O
>>> import module_c
ImportError: No module named module_c
>>> import module_o

$ rm *.pyc *.pyo
$ PYTHONPATH=modules.zip python
>>> import module_c
module_c
>>> import module_o
module_o

$ PYTHONPATH=modules.zip python -O
>>> import module_c
module_c
>>> import module_o
module_o

I've create a patch suggestion to remove this inconsistency[3] (*I* think
zipimport behaviour is better).
