Hi Jim. I guess I missed the boat on app construction which I have
clarified hopefully below. I am speaking of using zc.zope3recipes.
As far as site.zcml. I think I'll need to experiment. At this
point I see a strong incentive to automate. Too many packages -
too little time and too many errors without. I want z3 development
to be fast and enjoyable and I don't want to hate configuration
but I honestly hate trial and error approaches. This is where I
feel I am at with the site.zcml - particularly reconstituting zope
and apps from packages and eggs in this context (particularly with
the ordering of includes). Many thanks.
David and Jim,
As far as I can determine from this thread (I have some difficulty
following parts of David's long mail as well) you two are agreeing. :)
Jim, is it correct that you'd like the zope 3 recipe to grow an
option to auto-construct a site.zcml based on egg dependencies?
No. I suggested that packages that have ZCML and that depend on
other packages that have ZCML should include the ZCML of the packages
they depend on. If this was common practice, then I don't think that
constructing a site ZCML would be that hard.
Tres's argument is that since there is no system to override ZCML
auto-inclusion of configuration should not be implemented yet. But
Jim seems to disagree with this (and I do too).
There isn't a good way to cancel configuration done by included
packages. I've found that in practice this usually doesn't matter,
but I agree with Tres that it is a significant hole.
I also don't understand David's problem with buildout times. The
option -N helps a lot. Jim, is there anything to say for actually
making -N the default behavior of buildout?
No, But I can say something against it. :) Making it the default
would make buildout's default behavior less deterministic. It is
easy for people to change the default for their own use by putting:
[buildout]
newest = false
in their ~/.buildout/default.cfg file.
