[ZODB-Dev] Python 3 support for relstorage
Hi all, Recently I wanted to have relstorage on Python 3, so I made a fork at http://github.com/ztane/relstorage, and tried to make it polyglot with minimal changes. I did not even use six as I didn't want any extra imports (I just realized later that ZODB was using it), just wrote a single module compat.py with all the differences in invocations (mostly). Now, with PostgreSQL setup.py test passes 256/256 on Python 2.7 and 255/255 on Python 3.4. There is the one test checkNonASCIITransactionMetadata doing setUser with non-ascii characters that did not seem to be supported in transaction and ZODB themselves so I dropped it out for PY3. I am not an expert on relstorage (never used it before), so I am not sure how buggy it is - I needed to change the *tests* themselves a lot; also, mysql-python is not available for Python 3, I do not care enough about MySQL to install it nor to make it use another module, and I can't afford Oracle ;). I wrote the code to work on Python 2.6 also (it avoids `except Cls as e` for example), however I do not have Python 2.6 installed either.

[ZODB-Dev] Python 3
Hi all, Is there a roadmap for getting ZODB to work on Python 3 or is that beyond the realms of possibility? Possibly, using a Python 2 ZEO server and connecting using a Python 3 ClientStorage?

Py3K support is unlikely a major goal for us right now. -aj begin:vcard fn:Andreas Jung n:Jung;Andreas org:ZOPYX Ltd. Co.

The biggest hurdles for packages that have substantial test suites and development tool support (like ZODB) will be the availability of tools. At this point, setuptools and zc.buildout don't support Python 3 yet; until setuptools is available there's unlikely to be any movement to supporting Python 3 in the Zope world. Hopefully, someone will deal with that fairly soon, but I can't bring myself to hold my breath for it. -Fred -- Fred L.

My impressions that many more liberties were taken with the standard library than with the language itself, but I haven't been able to pay very close attention.

I think it will be rather hard and there are much much ... much higher priorities, at least for me. Possibly, using a Python 2 ZEO server and connecting using a Python 3 ClientStorage? That would be a goal. I don't think it reduces the effort all that much.
