[ZODB-Dev] failed installation attempt on Vista
Even though I've used ZODB before (not standalone on Windows, however),
I've been unable to get it installed, and barely able to follow your web
presence.
The general index of persistence tools for python,
http://wiki.python.org/moin/PersistenceTools, leads to
http://wiki.zope.org/ZODB. That in turn directs one to launchpad, but
that is a red-herring for either installing the package or discovering
documentation. launchpad in turn directs one back to
http://wiki.zope.org/ZODB.
Downloads go to http://pypi.python.org/pypi/ZODB3. You pick the latest
version, and there is nothing to download on the page. The installation
instructions suggest using easy_install. The installation instructions
there direct you to http://pypi.python.org/pypi/setuptools. That in
turn has an installation and download section. That sends you to
http://pypi.python.org/pypi/setuptools#files, which finally provides a
windows installer.
Having installed easy install, which itself has some not easy
installation instructions (if you have a prior version installed do x y
and z), I then found no help on it. Going back to the easy install web
pages for useage, I tried this:
shell
easy_install ZODB
easy_install ZODB
Searching for ZODB
Reading http://pypi.python.org/simple/ZODB/
Couldn't find index page for 'ZODB' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading http://pypi.python.org/simple/
No local packages or download links found for ZODB
Best match: None

I'm trying now with ZODB3, which seems to be going better.
And the documentation, as the package and web pages note, is in sad state.
This is all very awkward, and really quite unapproachable.

[ZODB-Dev] ZODB3 installation ambiguous conclusion
easy_install ZODB3 looked fairly good during installation until the end: quote Processing transaction-1.0.0.tar.gz Running transaction-1.0.0\setup.py -q bdist_egg --dist-dir c:\users\ross\appdata\local\temp\easy_install-cw1i4f\transaction-1.0.0\egg-dist-tmp-z7nrfd Adding transaction 1.0.0 to easy-install.pth file Installed c:\python26\lib\site-packages\transaction-1.0.0-py2.6.egg Finished processing dependencies for ZODB3 WARNING: An optional code optimization (C extension) could not be compiled. Optimizations for this package will not be available! Unable to find vcvarsall.bat /quote This seems to say things will work, just not as fast as they could. But I'm a little puzzled why things would work at all, since I don't have a build environment on the machine (well, there is a compiler that's part of the MS SDK, but I'm not really sure how capable or operational it is--it did seem to compile some sample C code in the kit). Is there a pure python fallback for the C code? I thought ZODB had some C-level magic.

Is there a pure python fallback for the C code? I thought ZODB had some C-level magic. ZODB requires C-code modules to work, but pre-compiled win32 eggs are available, and presumably that is what easy_install picked. It's not clear to me what generated that warning, but then I don't use Windows.

[ZODB-Dev] No module named Persistence
The IPC10 presentation says #Works as a side-effect of importing ZODB above from Persistence import Persistent I tried that (with the indicate other imports first). It led to a No module error. I tried commenting out the line, since the comment could be interpreted to mean that importing ZODB already does what's necessary. But there was no Persistent class defined I could use. I tried from Globals import Persistent, as suggested in a 1998 posting. This produced No module named Globals. Suggestions?

That is the old Zope2 persistence base class. Try 'from persistent import Persistent'. http://docs.zope.org/zodb/zodbguide/prog-zodb.html#writing-a-persistent-class (note that guide has probably not been updated since ZODB 3.7, so don't expect any newer features to be documented there).
