[Zope3-Users] zope3, site-packages and easy_install
a short question on using eggs and zope3 dev/checkout together had a case yesterday: easy_installed zope.schema (and automatically its dependencies) easy_install adds its paths in front of all other paths to sys.path -- this broke my zope3 svn checkout; first sign: bin/zopectl debug didn't work anymore what should one suggest for development ? - using zope3 checkout with its own python interpreter - or remove site-packages from zope3 sys.path what to do in deployment environment ? - using zope3 deploment with its very own python interpreter - you never now when anyone will add another piece to site-packages i think this will affect buildouts too as they rely on a common python install.

Every deployment gets a private interpreter. The system interpreter can't be trusted since we don't know what patches may be been installed, or what might change in updates applied by a sysadmin. -Fred -- Fred L.

Interactively, use zopectl debug. This will give you an interactive interpreter with an app variable set to the top-level folder. Use zopectl run your_script to run a script with the same app variable set and ready for use. Of course you can use the lower-level ZODB APIs to open the database yourself.

Re: [Zope3-Users] Zope3 database activity
Thierry Florac wrote: Zope2 provided a nice tool in his control panel to view database activity (objects loads and stores, cache usage...). Yes. This is wildly useful for improving performance. In many applications, a good way to improve performance is to allocate a larger object cache using more physical memory. (Buying more RAM is a very cost effective hardware upgrade.) Two questions : - is there any way to get access to such information with Zope3 ? Zope3 uses the same ZODB that Zope 2 uses, so the necessary infrastructure is there. No one has written the equivalent UI tool AFAIK. - is it possible with Zope3 to setup cache size ?? Of course, using the same option in the zope.conf file.

[Zope3-Users] viewtemplate
Hi all I recently read Stephan Richter's blog post: http://blogs.lovelysystems.com/srichter/2006/09/20/the-skin-browser-and-lovely-systems-new-development-workflow and intendent scope of viewlets thread: http://thread.gmane.org/gmane.comp.web.zope.zope3.user/4652/focus=4652. I like the idea behind viewtemplate very much (separation of template and view code), but I've some problems with putting all of this together. Let me summarize: 1. Views and Viewlets belong to the layer 2. Templates belong to the skin 3. ViewletManagers belong to.. ? 4. Lovely's packaging practices says that: - views should be placed and registered in project.browser.layer.subpackage_for_the_view_impelentations - templates should be placed and registered in project.browser.skin package - viewletmanagers... ? ViewletManagers may have a class and a template, VMs are called from templates, viewlets are registered for VMs. Shouldn't it be resolved by template tag which registers a template with ViewletManager as it is done for Viewlets and Views? One more thing is a layer declaration such as (from Stephan's post): browser:viewlet name=bloglist for=myproject.interfaces.IBlog manager=myproject.browser.interfaces.IContent view=myproject.browser.blog.BlogPage class=myproject.browser.blog.BlogList layer=myproject.browser.IProjectLayer permission=zope.Public / while template is registered for skin: browser:template template=bloglist.pt layer=myproject.browser.skin.IProjectSkin for=myproject.browser.blog.BlogList / I'm pretty new to the skinnig concept. What is the purpose of IProjectLayer? Is it that views and viewlets are registered to IProjectLayer which is project marker interface, while templates are registered for skins. As a result we have stable project's code base and skins which are just templates. Any discussion on the above topics will be appreciated :) -- Jakub Wisniowski ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Re: [Zope3-Users] Access to persistent Zope tables/classes in ZODB
Thanks Jim, I had gotten to the following point (although you have now shown me a better way to get there, I was using FileStorage): ZODB.DB.DB object at 0x137e910 {'Application': zope.app.folder.folder.Folder object at 0x1377d70, 'zope.app.generations': persistent.dict.PersistentDict object at 0x1377db0} zope.app.folder.folder.Folder object at 0x1377d70 OOBTreeItems object at 0x1386228 print f1[0].keys()[1] Rob's buddies print f1[0].values()[1] buddydemo.buddy.BuddyFolder object at 0x1377f30 print f1[0].values()[1].__getitem__ bound method BuddyFolder.__getitem__ of buddydemo.buddy.BuddyFolder object at 0x1377f30 This is where I get stuck. Been going over the sources to figure out how to iterate over these. You're 2nd point, about using ZEO, is also very valid (I need to just read my 'buddies' and send the data down to a bunch of embedded Linux based controllers but the ZODB will be locked). I did notice since I did this, bin/runzope acts differently (on this Zope/ZODB?). I created a new instance in 121 and transferred all applications and the new instance works fine: Robs-Laptop:~/Projects/Zope/Zope3/One2One rob$ cd ../121/ Robs-Laptop:~/Projects/Zope/Zope3/121 rob$ runzope -- 2006-10-27T14:45:57 INFO root -- HTTP:localhost:9090 Server started.

Developer mode can be turned off in etc/zope.conf Total: 0 tests, 0 failures, 0 errors Robs-Laptop:~/Projects/Zope/Zope3/One2One rob$ Any idea what causes this? Anyway, thanks again for your quick response!
