I'll say it one more time.
The roadmap states under the "Simplifying the Zope experience"
* simple tasks should be simple!
Now, code required to extract a value from the environment:
try: value = sanitize(os.environ.get("SOMETHING", default))
# where 'sanitize' is in reference to any conversion procedures required
# prior to the use of 'value' by program code
Pretty simple. Enter ZConfig:
$ du -sk ZConfig
374k of work devoted to replacing os.environ.get and its sanitizing
code, and the result is a XML config file. I'm not saying this all
for naught, but really, it should give you pause. Just how much have
you really simplified configuration by doing this?
Personally I think the problem of Zope's configuration hassles has
been mis-identified. ZConfig cleans up and centralizes a maze of
badly strewn out configuration code. It will extend the lifetime of
the Über-server concept ZServer employs. It does nothing to prevent
the same mess from happening again, down the road. I believe a more
lasting approach is to seperate the servers into small individual
programs which only do 1 thing, and do it well. Then you combine
those servers under a unified mangement framework, connect them
together by using common communication idioms, the idea being--and
follow me here, to use small programs combined together to provide a
larger service. Sound familiar?
