Launching external apps to process uploads to LocalFS, possible?
by Chris Beaumont 08 May '03

08 May '03

I'm setting up a document repository that allows people to upload files (Using Zope) to a LocalFS directory. Those files then become visible through the Zope management interface. Is there any Zope friendly way to launch external Linux apps to process them once they have been uploaded? I'd like to translate .dvi and Word .doc files into PDF using wvWare and dvipdfm. I suppose I could use a cron job and a shell script to do the conversion at regular intervals, but I'd rather do it immediately. I guess what I am asking is if Zope's Python can be told to launch apps on the hosting machine.. But that seems like it would be a major security hole, so I understand if its not possible.. -Thank you, Chris

stx document

I've installed cmf and plone. plone renders structure docs correct? I created a folder outside my plone site, and am playing with different objects -- but I don't see that I can add a structure document object. Its not available from the pulldown. so, does plone have its on method form rendering structure text docs, and if so, will I mess it up if I add structured text as a new product? Or, is there a way to get zope to render structure text without having to add it now - ie use some plone object? -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, it will make criminals out of innovators"

Setting Default Roles/Permissions for product
by Stacy Roberts Ladnier 08 May '03

08 May '03

How do I set the default roles of for a Python product's permissions (keep in mind I have added 3 new roles) programmatically inside the product code? In my product classes, I use ClassSecurityInfo and I do make sure to InitializeClass after declaring all my security settings. In my security declarations, I include multiple lines similar to : security.setPermissionDefault('Add records', ('Custodian')) My permissions are shown on the main security tab. However, some of the permissions pick up the default roles, some do not, and others have NO roles defines. Can someone please point me in the right direction? Thanks in advance!!

Cannot add any ZClass
by Andreas Pakulat 08 May '03

08 May '03

Hi, I tried to add a ZClass to my Zope-Install, but I get this everytime I click the add Button: Error Type: KeyError Error Value: title This happens regardless of what is typed in the title-field. All the other fields seem correct to me: id: MitteilungClass title: (should be) Class for News metatype: Mitteilung derived from OFS:File and both checkboxes are on. Is this a bug in my Zope (2.6.1) ? Andreas -- You will live a long, healthy, happy life and make bags of money.

RE: [Zope] Launching external apps to process uploads to LocalFS, possible?

Security-wise, just hard-code the behavior into product code, perhaps hack LocalFS to meet your needs? I think this might be what you want, if you want the applications doing the work to detach from Zope (otherwise use os.system() ). This will work on Unix, and I think on Win32. from os import spawnv, P_NOWAIT spawnv(P_NOWAIT, '[pathtoprog]', ('[programname]',)) i.e.: >>> from os import spawnv, P_NOWAIT >>> spawnv(P_NOWAIT, '/usr/bin/python2.1', ('python2.1',)) spawnv will return an integer pid number, which you could use or ignore. If the parent Python process (in this case Zope) is killed or shutdown while the child process (spawned process) is running, the child process will be re-parented to init and continue running until done. -----Original Message----- From: Chris Beaumont [mailto:cbeaumon@msri.org] Sent: Thursday, May 08, 2003 11:57 AM To: zope(a)zope.org Subject: [Zope] Launching external apps to process uploads to LocalFS, possible?

publishing a double-underscore method?
by Dylan Reinhardt 08 May '03

08 May '03

Hi all, I'm working on a product where I want to publish the results of a custom __getattr__ method. I realize overriding __getattr__ isn't generally recommended, but it fits my specific requirements for this product. The problem I'm having is that even very trivial returns from __getattr__ kick out the "empty or missing docstring" error. A trivial example that doesn't work: ---------- security.declarePublic('__getattr__') def __getattr__(self, name): """ I have a docstring, not that it seems to matter """ if name == 'test': return 'this is a test' else: raise AttributeError, name ---------- Here's what I actually want to do: ---------- def __getattr__(self, name): if name in self.some_mapping.keys(): return self.some_method(name).__of__(self) else: raise AttributeError, name ---------- Playing with this a bit, it appears that anything I attempt to return from __getattr__ is checked for publishability **after** the return value has been computed. Since double-underscore methods are not typically published, I'm not surprised that I'm having trouble. It seems there should be some directive that explicitly permits method publication in such cases. Is there such a thing? Thanks in advance. I'm using Zope 2.6.1 on Gentoo, if it matters. Dylan

RE: [Zope] custom searching by field
by sean.upton＠uniontrib.com 08 May '03

Zope's ZCatalog uses indexes with the names of the attributes or accessor methods that get your field values. If you have an index called 'manager' that is a FieldIndex, you can search that for an exact value, and nothing else will get searched. This, of course, assumes you write templates and scripts to query the catalog for the right index.
