Re: [Zope-dev] List of packages in ZTK
Hi, On 05.07.2009, at 07:06, Lennart Regebro wrote: 2009/7/5 Stephan Richter srich...@cosmos.phy.tufts.edu: To be honest, I am very disappointed by this list. It is totally meaningless to me since it does not represent any list with which I can build even a fairly simple application today. There is not a single z3c package in there. As I understand it, ZTK is not meant to build applications on. It's meant to build application servers on. ZTK is supposed to be tha base on which we build things like Grok, Plone, and yes, Zope 3. I'd like to mention repoze.bfg here. It takes a fairly small set of zope.* packages. What the ZTK is will be finally defined by the included packages. From a user's (developing with ZTK) perspective, I'd appreciate a small good documented well tested and stable set of tools to build web applications on regardless of which server or which db I want to use. Christian's list represents that very well, IMHO I'd kick a few packages I don't use at all. And where is zope.catalog? BTW z3c.* packages in the ZTK would baffle me a lot, OTOH renaming z3c packages just to fit into the ZTK seems a bit unorthodox. Very important are the tools and best practices surrounding the ZTK. Where do I start to get a state of the art but simple and inviting - from a developer's perspective - web application?

Re: [Zope-dev] A suggestion for changing exception handler when loading 'c' optimisations to make modules more friendly for GAE
Hi,
yes, I'd really appreciate such a modification. Then I could delete
the regarding code in my rod.recipe.appengine, which provides a dummy
implementation of imp.load_dynamic.
Tim, do you have a list of the concerning packages? I could help
making these changes. A good reason to file an application for commit
rights :-)

Hi all
Can I make a suggestion that would make a couple of modules more gae
friendly ;-)
zope.interface and zope.i18nmessageid have 'c' optimisations which
obviously don't work under app engine.
When these modules are imported you get the following exception.
gae/1.333250465889549129/zope/i18nmessageid/
_zope_i18nmessageid_message.py,
line 6, in __bootstrap__
imp.load_dynamic(__name__,__file__)
File /base/python_dist/lib/python2.5/py_imp.py, line 116, in
load_dynamic
raise NotImplementedError('This function is not supported on App
Engine.')
Unfortunately the code (in this case in zope.i18nmessageid.Message)
does the following which doesn't deal with the Exception
raised by the app engine runtime.
try:
from _zope_i18nmessageid_message import Message
except ImportError:
pass
To make it more gae friendly I think we should change these
occurrences to
try:
from _zope_i18nmessageid_message import Message
except ImportError, NotImplementedError:
pass

Tim

This actually feels like a bug in GAE to me... This should be an
ImportError...
Sorry, I don't agree. We assume an imp.load_dynamic function from what
we read in the python documentation. But the implementation in GAE
does not provide the expected api. So the NotImplementedError seems
absolutely correct to me (see
http://www.python.org/doc/2.5.2/lib/module-exceptions.html#l2h-114)
.

At least an ignore in the app.yaml isn't feasible. I'm sure there's a way to do it. It will just take some digging. Maybe there's a way to tell setuptools not to do it or maybe there's enough meta data laying around for buildout to undo it. For example, the EGG-INFO/SOURCES.txt has a list of the original files in the distribution, so it should be easy enough to figure out where these extra bogus files are. Great idea to examine EGG-INFO/SOURCES.txt, Jim! I just added this to my recipe (http://pypi.python.org/pypi/rod.recipe.appengine) and got rid of the horrible monkey patch for imp.load_dynamic. Now it does exactly what Tim wants and excludes the optional c extension stuff (plus .pyo, and .pyc files) in a gae buildout. I'm planning to add an option for not deploying the additional packes as a zip archive if the gae file limit will not be exceeded.

[Zope-dev] several zope.* libs within gae (was ZCML implementations: where should they go)
Hi, Shane Hathaway wrote: Hanno Schlichting wrote: Wichert Akkerman wrote: I'ld rather not see a whole slew of extra packagse appear. I also wonder how the extra number of packages and increasing size of sys.path influence performance and restrictions on environments like GAE. For environments like GAE you don't want setuptools and its magic to be part of your application. This is were repackaging your entire app into one zipped egg or some other flat structure comes in handy. Setuptools and eggs are a distribution format from my point of view. They are certainly not the best way to deploy your applications. The growing sys.path is affecting performance to some degree in all deployment environments. Well, zc.buildout ought to be able to eliminate this concern for GAE deployment. I haven't tried the recipe below, but it certainly seems like the right idea. http://pypi.python.org/pypi/rod.recipe.appengine I released a new version today. It's a lot easier now to use several eggs within gae. This test thingy http://zpttest.appspot.com/ uses zope.interface and zope.pagetemplate plus their dependencies. I'm planning to release another sample project maybe during easter holidays. It's much more fun since you zope people cleaned up a lot of dependencies and unveiled zc.buildout. Thanks!
