OK, I'm trying to figure this out. As I understand it, the result of the
incompatibility is that:
import Image
Fails in Zope 2 if PIL is installed because Zope 2 (OFS) has it's own Image
module.
For quite some time, PIL has been delivered as both a package and with a
pth file, so you can use the old style:
import Image
or the newer:
from PIL import Image.
The PIL directory (package) has a lot of modules in it, so I really
don't want them all importable at the top level. So I generally remove
the .pth file, so that only the later works on my systems, with my code.
I'd be a bit happier if "import Image" raised a deprecation warning, but
I'm not sure how you'd do that. (I actually did help do that for the
GDAL package, but that was set up differently - they actually had all
their stuff dumped directly into site-packages).
But it's not hard to have ZOPE remove the pth file if that's what you want.
And when it comes down to it, there is no way to remove all possible
name clashes --every package has to have a top-level name -- if ZOPE
used a package called "PIL", you'd still have a clash.
But python does allow the "import as" construction, so you can always
patch your own systems by changing the name of a package.
My tiny nit about "standards":
Having a __version__ attribute is a very common convention, if not a
standard -- it would be nice if PIL supported it -- and that's a trivial
patch:
in Image.py, add:
__version__ = VERSION
in __init__.py
add:
from Image import __version__
Another comment:
If someone is doing a "friendly" fork -- it's really the least you can
do to be very public about what the heck the "issues" are that you want
to address that are not being addressed by the main version.
At least a packaging
fork means that someone's over there is producing something more than
invectives, but I'd still prefer a patch.
Is packaging the only "issues" this fork is for?
