Problem w/ Fresh Build

Hi; I'm building Z29 on a new FBSD62 server from port. I've done this before with no problem. I followed the instructions exactly. Now, I get this: 2007-12-24 22:26:50 ERROR Zope Could not import Products.ATContentTypes Traceback (most recent call last): File "/usr/local/www/Zope29/lib/python/OFS/Application.py", line 708, in import_product File "/usr/local/zope/Products210/ATContentTypes/__init__.py", line 37, in ? from Products.ATContentTypes.config import HAS_LINGUA_PLONE File "/usr/local/zope/Products210/ATContentTypes/config.py", line 30, in ? from Products.ATContentTypes.configuration import zconf File "/usr/local/zope/Products210/ATContentTypes/configuration/__init__.py", line 25, in ? from Products.ATContentTypes.configuration.config import zconf File "/usr/local/zope/Products210/ATContentTypes/configuration/config.py", line 29, in ? from Products.ATContentTypes.configuration.schema import atctSchema File "/usr/local/zope/Products210/ATContentTypes/configuration/schema.py", line 29, in ? from Products.ATContentTypes.configuration import datatype File "/usr/local/zope/Products210/ATContentTypes/configuration/datatype.py", line 25, in ? from Products.CMFCore import permissions as CMFCorePermissions File "/usr/local/zope/Products210/CMFCore/__init__.py", line 24, in ? import five.localsitemanager File "/usr/local/zope/Products210/CMFCore/src/five/localsitemanager/__init__.py", line 2, in ? from zope.component.globalregistry import base ImportError: No module named globalregistry Traceback (most recent call last): File "/usr/local/zope/295/lib/python/Zope2/Startup/run.py", line 56, in ? run() File "/usr/local/zope/295/lib/python/Zope2/Startup/run.py", line 21, in run starter.prepare() File "/usr/local/zope/295/lib/python/Zope2/Startup/__init__.py", line 98, in prepare self.startZope() File "/usr/local/zope/295/lib/python/Zope2/Startup/__init__.py", line 257, in startZope Zope2.startup() File "/usr/local/zope/295/lib/python/Zope2/Startup/__init__.py", line 47, in startup starter.setConfiguration(cfg) File "/usr/local/www/Zope29/lib/python/Zope2/App/startup.py", line 46, in startup File "/usr/local/www/Zope29/lib/python/OFS/Application.py", line 685, in import_products File "/usr/local/www/Zope29/lib/python/OFS/Application.py", line 723, in import_product KeyError TIA, Victor

Rehashing GPL vs ZPL is off topic here, because the ZPL is the *mandated* license for any code contributed into the zope.org repository: that choice is not subject to debate.

I would be careful about using labels like "anti-sharing" to describe individual licenses. As you acknowledged, both licenses are used to "share" software. ZPL-shared software comes with few strings attached. GPL-shared software comes the "share alike" string attached. It's a bit of a semantic question which is more true to the spirit of *sharing* so I'm going skip that debate. Chris McDonough didn't appear to label the GPL as "anti-sharing". On the contrary, it's the existence of *both* licenses in the same community that he appears to describe as anti-sharing. And since in the Zope community, the ZPL came first and is the core license, it's a legitimate complaint that it's the later adoption of a different license by a subcommunity that is the primary culprit.

To use it (assuming that you name it URL) follow this example: url = context.URL() scheme, location, path, parameters, query, fragment = u.urlparse(some_url) Hope it helps. Zénrique.

Using zoperoot.misc_.MyProduct
by Peter Bengtsson 16 Dec '07

16 Dec '07

As far as I can see, an advantage with attaching static stuff to OFS.misc_.MyInstalledProduct is that it becomes available globally which makes sense to avoid loading a different icon URL for each www icon in the ZMI of a product. Makes sense also for example if you have one Zope with 10 different instances because then there's just one on /misc_/MyProduct/screen.css to cache and download for the browser if you've placed a static file there called that. A drawback seems to be that errors happening in /misc_/MyProduct/static-content isn't reported in the error_log. This makes it hard to spot bugs in objects in there and, more commonly, NotFound errors. Is there anything I can do about that or should I not expect so much and instead use the instance? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

urlparse equivalent
by David Bear 15 Dec '07

15 Dec '07

I wanted to use urlparse to handle manage some url rewrites but it's not importable.. Is there any zope functional equivelent that I can use to parse urls? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"

Appending to a file via manage_edit?
by Jeff Gentry 14 Dec '07

14 Dec '07

I've been looking around for this, but can't seem to find anything. I'm assuming that it is just not possible, but thought I'd ask just in case. For File objects, I see that manage_edit() has the parameters: title, content_type, precondition, filedata & REQUEST. Setting something in the filedata parameter will replace the file's current data with that. This implies (to me at least) that the only way one can edit a file is a complete rewrite. Does there exist a way to simply append data to the end of the file? For instance, if one wanted to write to a file line by line, is that possible in Zope? Thanks

I have this error trying to launch the instance: Error: could not load package Products.rotatezlogs: No module named rotatezlogs Package name: 'Products.rotatezlogs' File name: 'component.xml' Package path: None Is strange because with this rotatezlogs (1.0) and the same zope.conf works fine in other computers I own Any idea?
