[FE-discuss] Future Formencode releases

[Chris Lambacher]

Hi Everyone,

I'd like to get a 1.2.5 release out the door so we can properly start on
Python 3.x support and a 1.3.0 release. I've copied the remaining issues
from sourceforge to github and added the blockers for a 1.2.5 release to
the 1.2.5 milestone. Any help people can give with triaging these issues
would be greatly appreciated. Many of the outstanding bugs are for htmlfill
which I don't use so if you are an htmlfill user and can comment or provide
a concrete test case that would be very helpful.

The plan is that 1.3.0 will drop support for at least python 2.3 and
probably 2.4 and 2.5. Anyone using 2.4 or 2.5 should speak up about their
need for continued support.

-Chris

I have something coming up this weekend, but maybe the next weekend? Did
you want to set a date for some sort of mini-sprint?

We use FormEncode in MediaCore (www.mediacorecommunity.org) and there are
still many customers using 2.4 (roughly 20%). I plan on supporting 2.4 in
MediaCore for the foreseeable future (2-3 years) though some smaller features
might be 2.6+.

I'll stop supporting Python 2.4 for all libraries I maintain on March 2017
when RHEL 5 goes EOL.

That being said MediaCore uses FormEncode only in simple functionality and we
don't need new FormEncode features so I guess we can stay with 1.2.5 for quite
some time.

RHEL6 looks like it supports 2.5 and 2.6 would you then need 2.5 support or
your app would work with the latest version available on the system OS?

I'll do a maintenance branch for 1.2 before we start on 1.3 and we can
continue to do bugfix releases but maybe people using older versions Python
should start pinning their versions or FormEncode to < 1.3 so that you
don't get version that don't work for you on PyPI.

I want to have a mixed 2.x 3.x code base and not have to deal with 2to3 and
some of the things you need to do to make it work with older versions of
Python (like <
http://docs.pythonsprints.com/python3_porting/py-porting.html#handling-exceptions>)
are not pretty. Making 2.6 be the lowest supporte version make things much
simpler.

RHEL 6 provides only Python 2.6.

MediaCore works on Python 2.4-2.7 (whatever the user chooses). The main
difficulty is that it's software installed by random users on their various
environments. And it turns out a number of hosts still only provide 2.4
(usually on RHEL/CentOS 5).

Version pinning is no problem for MediaCore, that was done by the old
maintainers anyway (we host all dependencies on the project server so also
Pypi downtime does not affect users).

A stable 1.2 branch with security fixes only would be actually great solution
to us!

I didn't have any troubles using 2to3 on a code base and thus supporting
Python 2.3 - 3.2. The only real PITA is doctests which are (IMHO) not
portable. Heck, I even had troubles for different versions of Python 2.x when
the repr output for a class changed (Decimal in 2.4 vs. 2.5+).
