Migrated issue, originally created by Michael Bayer (@zzzeek)

• libraries (stringio, etc)

I want to work on this, but I need to ask a question to @zzzeek first: could we introduce tox into Alembic for cross-VM testing?

using tox just means you have an .ini file there right? we don't need it for continuous integration, if you see here we just have separate jenkins builds per platform. you can just use the .ini locally ?

I meant, do you mind if I add tox.ini file into the source tree?

Or should I add tox.ini into .hgignore list?

if/until I totally get into tox for sqlalchemy and everything, put it in .hgignore would be better for now

Okay, and one more question: SQLAlchemy 0.8 currently supports Python 2.5–3.3, so is it the same for Alembic?

@zzzeek It currently seems impossible to be parsed on Python 2.5. Does not Alembic support Python 2.5?

Michael Bayer (@zzzeek) wrote:

lack of 2.5 is not official but that's how it seems, sure. 2.5 is gone very soon in sqlalchemy too (django already dropped 2.5).

If we don’t need to support 2.5, is there still any reason to use except Exception: e = sys.exc_info()[1] instead of simply except Exception as e:?

no, let's go with 2.6 idioms all the way. we'll need to add an explicit message to the docs that 2.6 is required.
