New submission from Karen Tracey <kmtra...@gmail.com>:
The fullname parameter to zipimporter find_module is documented to be a "fully
qualified (dotted) module name". (From
http://docs.python.org/library/zipimport.html#zipimport.zipimporter.find_module.)
However, passing a fully-qualified dotted module appears to never work. Rather
it appears that you must use the file system path separator instead of dots.
For example on Windows:
C:\>echo %pythonpath%
\tmp\blah-1.0-py2.6.egg
C:\>python
Python 2.6.5 (r265:79096, Mar 19 2010, 21:48:26) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from blah.models import speak
>>> speak.__file__
'C:\\tmp\\blah-1.0-py2.6.egg\\blah\\models\\speak.pyc'
>>> speak.sayhi()
Hi from blah.models.speak sayhi function.
The egg has top-level blah package and under it models, it appears to work fine
for normal use. But zipimport zipimporter find_module won't find the models
sub-module using dotted path notation:
>>> import sys
>>> sys.path[1]
'C:\\tmp\\blah-1.0-py2.6.egg'
>>> import zipimport
>>> zi = zipimport.zipimporter(sys.path[1])
>>> zi.find_module('blah')
<zipimporter object "C:\tmp\blah-1.0-py2.6.egg">
>>> zi.find_module('blah.models')
>>> zi.find_module('blah/models')
>>> zi.find_module('blah\\models')
<zipimporter object "C:\tmp\blah-1.0-py2.6.egg">
>>>
On Linux, the 'blah/models' version is the one that works.
Tested as far back as Python2.3 and as far forward as 2.7a3.
