Re: [Python-sybase-misc] new SQLAlchemy dialect; Python 3?

[Sébastien S. <sa...@us...>]

Hi Mic,

great to hear about that SQLAlchemy will support Sybase.

You should note that python-sybase is unfortunately not perfectly DBAPI
compliant because of some limitations of sybase which make it hard to
perfectly follow the specification (problems with nested requests
notably). If you encounter such problem, and can reproduce it with a
unitary test, I would be happy to help correct it in python-sybase.

Also please note that the trunk has quite a lot of bug corrections
compared to the last release, so I would suggest to use it rather than
the latest official release (I should take some time to make a new release).

The development of python-sybase is rather slow at the moment; I work on
it for the needs of a legacy project at my work, but Sybase is not the
priority at the moment and so I mostly do maintenance and small bug
corrections. I didn't have time to make a proper release for a long
time, though I hope to have more free time for that this summer.

At some stage we will have to get the legacy project on which I work to
support sybase in the latest version. When that will happen I will be
able to dedicate a full month or 2 to improve python-sybase, mostly
concerning performances (and unicode support). I should be able to also
check Python 3 compatibility  at the same time. But in the meantime, I
can only ensure small bugs corrections and answering to emails.
