straw poll: ParsedXML requirements

Hi there,

I'd like to hold an informal poll on requirements for any new release of
ParsedXML. There was some discussion on whether it should continue to
support Zope 2.3 and Python 1.5.2, or if it would be okay if it supported
Zope 2.4 and Python 2.1 only. The latter option would make life easier
on the developers, but if there are a lot of users who want to upgrade
ParsedXML but not their Zope yet, we should continue to support
Python 1.5.2 for a while longer.

So, what do people think? I'm especially interested in hearing from current
users of ParsedXML, though input from others would be interesting as well.
Please send your replies to the list also so we can discuss things further.

Regards,

Martijn

+1 Zope 2.4/Python 2.1

Burning Tiger is hoping to use ParsedXML extensively as the basis for
supporting a whole slew of XML document types. We've already made the
move to Zope 2.4 and Python 2.1, so only supporting those levels and
above is OK with us.

And I'm looking forward to a new release, as I'm currently having
trouble with ParsedXML and Zope 2.4...

I'm sure the answer is in the archives, but I haven't had the time
lately for archive mining, and my headlamp is busted. %-)

RE: straw poll: ParsedXML requirements [In reply to]

You will get conservative-implementation folks who have a lot of production
infrastructure still on Zope 2.3.x and Python 1.5.2 (like me, right now);
that said, I think the best approach is to release an 2.3.x/1.5.2 compatible
interim release with your proxy speedups, see if the expat leak bug (is that
fixed yet, and better yet, what is the nature of the problem?) can be fixed.
Label that release as the 'last' ParsedXML release supporting Python 1.5.2
and Zope 2.3.x. I think that is fair, then move on, supporting only new
releases of Zope/Python.

We're using ParsedXML to hold large-ish XML documents (10-100k) and provide a
number of different renderings on the fly (it's a Learning Management System,
different users get different views.

Python 2 and Zope 2.4 is what we're using, and the closer we get to Unicode
support, the easier our jobs will be (as we're trying to support a whole
external authoring cycle in this.) Performance is a big issue for us.

And me.

This sounds like a good plan, except that the 1.5.2/2.3.x compatible
branch should still get bugfixes if bugs are found (unlikely, I know).
In short, the release/branching strategy should take it's cue from
Zope's.

+1 Zope 2.4 & Python 2.1
Between Unicode support and overall better XML tools in Python 2+, I think it would be a real drain on resources to be backwards-compatible.

I know there's an expat segfault bug, but what is this expat leak bug?

The main sticking point would be the unicode support. I know some code
in ParsedXML currently works with both non-unicode strings and unicode
strings, but some obviously doesn't. Not resolving this issue and
fixing all the unit tests would be releasing a buggy version of
ParsedXML (for Zope 2.3 or Zope 2.4 or worse, both :).

Anyway, something like this would be my own preference if we can't move
on to Zope 2.4 directly. (now you know my agenda if it wasn't obvious
anyway :)

RE: straw poll: ParsedXML requirements [In reply to]

Well, I would think that slightly non-compliant (i.e. no unicode support)
for old releases of Zope would have to do.

I'm not sure about the expat bug; perhaps I am mistaken... just remember
hearing something about something like that a while back...
