Re: z3c.form 2.0 release? [In reply to]

Hello Michael,

I'm trying to make z3c.pt optional at
svn://svn.zope.org/repos/main/z3c.form/branches/adamg-z3c-pt-optional
because it just pulls in too many packages from the trunk that makes
it impossible to make a sort of compatibility layer for KGS 3.4.

Where being unable to use z3c.form with KGS 3.4 would be a HUGE loss.

Hello Adam, â€“â€“

The z3c.pt package shouldn't have difficult dependencies; it depends
on zope.i18n >= 3.5 but reasons unknown to me (Hanno CC'ed).

Note that the package no longer depends on ``lxml``.

The zope.i18n 3.5 dependency is used for the optimized i18n support in
Chameleon. I ported all the performance tweaks we made in Plone and
PlacelessTranslationService over time back to zope.i18n in that release.

Chameleon uses the zope.i18n.negotiate function added in 3.5 to
negotiate the language once per template instead of in every
zope.i18n.translate call. It works with a special fast_translate
function that skips the negotiation step completely and relies on the
negotiate function instead.

While zope.i18n 3.5 is not part of the 3.4 KGS it's way older then the
final 3.4 KGS release and only introduces backwards compatible new features.

Re: z3c.form 2.0 release? [In reply to]

Hello Malthe,

Well, the strong target is to make z3c.form 2.0 compatible with
KGS 3.4. (z3c.pt is somehow intertwined with z3c.ptcompat too.)
That's the goal am chasing though I'm quite busy right now.

I don't know the implications of requiring zope.i18n >= 3.5, but I can
say that it's the only dependency that could somehow cause
difficulties. Neither z3c.pt nor z3c.ptcompat have any odd
dependencies (package or version-wise).

Perhaps it's the obsolete dependency on lxml that's causing confusion;
I read a post or two on the list rightfully mentioning that this was a
very difficult dependency indeed.

I think at this point that z3c.form could have a strong dependency on
z3c.pt. Complete list of extra packages:

- z3c.pt
- chameleon.core
- chameleon.zpt
- sourcecodegen

Won't this cause problems if a z3c.form uses a template which calls a
macro from a traditional Zope page template? That is, make it
impossible to use z3c.form in a site that isn't using z3c.pt for
everything?

That was the reason for z3c.ptcompat; it lets you use one
import-location to switch between the two implementations.

Ah, right...I was remembering incorrectly why we were unable to use
z3c.ptcompat from within Plone. The actual reason is that it uses
ViewPageTemplateFile from z3c.pt when we need it from five.pt (I
think...it's been a while). But we were able to work around that by
adjusting the custom form and widget template factories in plone.z3cform

Re: z3c.form 2.0 release? [In reply to]

Hello Malthe,

The problem that I see here with lxml is that it is used for output
checking. Even worse z3c.form requires at least 2.1.1 of lxml, where KGS
3.4 has lxml nailed at 1.3.6.
This burpes already on buildout.
Now even if I would ignore this requirement for testing, (and testing)
how could I be sure that tests pass (with KGS 3.4)?

Take a look at
svn://svn.zope.org/repos/main/z3c.form/branches/adamg-z3c-pt-optional
and try to make the tests work and pass.
Look out, buildout.cfg has the KGS temporarily.

It might be possible to shed this testing dependency; ``lxml`` is used
because of its doctest-mode, but since then, Chameleon has been
equipped to render attributes in the ZPT order (instead of more or
less random). This was the raison d'etre to use lxml in tests.

Yes, I agree with that observation.

Re: z3c.form 2.0 release? [In reply to]

Hello Malthe,

Tiny problem is that the doctests seem to have the attributes in
lxml-sane order. That means just by removing lxml output-sanitization
even zpt output does not match the doctest.

Also, lxml is used to do some xpath queries.
