(Zope 2.8.7-final, python 2.4.3, linux2) I see the following error in my event.log a couple of times a day: 2006-10-02T07:13:00 ERROR ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 10.0.20.6:51398 at -0x68ce9834 channel#: 1517 requests:> (socket.error:(104, 'Connection reset by peer') [/usr/lib/python2.4/asynchat.py|initiate_send|219] [/usr/local/zope/Zope-2.8.7/lib/python/ZServer/medusa/http_server.py|send|417] [/usr/lib/python2.4/asyncore.py|send|332]) Anyone familiar with this?

Log in as another user

Hello, In Unix, there's the "su" command which admins can use to log in as another user. Is there a similar facility in Zope ? If not, is there a way for admins to view the passwords of their users ? Regards, Danny

Can't Install Plone!
by Javier Subervi 02 Oct '06

02 Oct '06

Hi; I'm working with Plone 2.1.2/Zope 2.7.8. I've had no trouble adding Plone sites before this. I was in my server working with some of the products I'd installed, all of which had been installed for some time. I went to install a new Plone for test purposes. I got this error: Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Products.CMFPlone.Portal, line 465, in manage_addSite Module Products.CMFPlone.Portal, line 437, in create Module Products.CMFPlone.Portal, line 384, in setupPlone Module Products.CMFPlone.Portal, line 223, in setupPortalContent Module Products.CMFCore.PortalFolder, line 408, in invokeFactory Module Products.CMFCore.TypesTool, line 925, in constructContent Module Products.CMFCore.TypesTool, line 335, in constructInstance Module Products.CMFCore.TypesTool, line 566, in _constructInstance Module Products.CMFPlone.LargePloneFolder, line 65, in addLargePloneFolder Module OFS.ObjectManager, line 276, in _setObject Module Products.CMFCore.CMFCatalogAware, line 198, in manage_afterAdd Module Products.CMFCore.CMFCatalogAware, line 60, in indexObject Module Products.CMFPlone.CatalogTool, line 386, in indexObject Module Products.CMFCore.CatalogTool, line 353, in reindexObject TypeError: catalog_object() takes at most 4 arguments (5 given) I decided to pull out all the Plone products and re-install with a fresh copy. Same error! What am I doing wrong? TIA, Javier2 --------------------------------- Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls. Great rates starting at 1¢/min.

A Quick Event-based Cataloging How-to for Zope 2
by Chris Withers 02 Oct '06

02 Oct '06

Hi All, Just been playing with this and found it remarkably easy, so thought I'd pass it on. If anyone can think of a better place than the mailing list archives for this, please let me know! Anyway, so I'm building a Zope 2 app where I need to index objects that are not catalog aware when they're added, modified or removed. To make things harder, this also needs to work via WebDAV. OK, so here's the solution: 1. Create yourself a python module called subscribers.py and put it on your python path, containing the following: from Acquisition import aq_base from zope.interface import Interface class ICatalogAware(Interface): pass def catalog(object,event): if aq_base(object) is object: # ObjectModified can get emitted during creation, # before the object has any acquisition context return object.getPhysicalRoot().unrestrictedTraverse( '/catalog' ).catalog_object(object) def uncatalog(object,event): object.getPhysicalRoot().unrestrictedTraverse( '/catalog' ).uncatalog_object('/'.join(object.getPhysicalPath())) 2. Slap the ICatalogAware marker interface on any classes you want to have indexed. Here's an example for the good old File object. Put the following in your site.zcml: <class class="OFS.Image.File"> <implements interface="subscribers.ICatalogAware"/> </class> 3. Finally, wire up the events so that files get indexed when they're created, modified or removed, again by adding the following to site.zcml: <subscriber handler="subscribers.catalog" for="ICatalogAware zope.app.container.contained.ObjectAddedEvent" /> <subscriber handler="subscribers.catalog" for="ICatalogAware zope.app.container.contained.ObjectModifiedEvent" /> <subscriber handler="subscribers.uncatalog" for="ICatalogAware zope.app.container.contained.ObjectRemovedEvent" /> 4. Okay, sadly you do need to get do some patching if you want changes to the file to result in recataloging :-/ Here's a diff: --- Image.py.original 2006-09-26 16:32:20.759375000 +0100 +++ Image.py 2006-09-26 16:33:11.384375000 +0100 @@ -33,6 +33,8 @@ from ZPublisher.HTTPRequest import FileUpload from ZPublisher.Iterators import filestream_iterator from zExceptions import Redirect +from zope.event import notify +from zope.app.container.contained import ObjectModifiedEvent from cgi import escape import transaction @@ -437,6 +439,7 @@ self.ZCacheable_invalidate() self.ZCacheable_set(None) self.http__refreshEtag() + notify(ObjectModifiedEvent(self)) def manage_edit(self, title, content_type, precondition='', filedata=None, REQUEST=None): Okay, well, hope this helps someone :-) Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

which operating system quandry
by David Bear 02 Oct '06

02 Oct '06

I know it has been asked many times which os is best for zope, I have yet to see a 'system administration perspective' in the discussion. By this I mean which os seems to have the most worry free administration of a zope instances. I have installed zope on both FreeBSD and various linucies and here is what I have observed: 1) Freebsd ports collection is an easy way to install zope -- the ports maintainer takes care of making the build files to handle all the zope dependencies including python versions, libraries, etc. However, I have yet to use portupgrade to apply security patches to zope instances running on freebsd. Does anyone know of using cvsupdate for getting security patches works over the ports collection of zope smoothly? 2) I've run zope on Red Hat and Suse linux. In both cases I found that I needed to install a different version of python than the one packaged with the distro becuase Zope had specific dependencies for new versions python. Applying patches to zope is manual. It has always been very inconvenient to build python and PIL in a separate run instances for zope. This seems like a major pain in the ... 3) I have never run zope on windows except for test versions of plone that were loaded through binary installers -- completely packaged with python and zope. While this is convenient, I don't know if I want to run a windows server for any publicly accessible site. 4) I am very interested to know how others manage zope sites. Are there any best practices? Are there any linux distributions that are more kind to zope than others -- meaning they don't have dependencies on old python versions, or they have a very good patch system (debian apt updates for zope??) -- 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"

Re: [Zope] POST from Zope to external server and receive RESPONSE
by David＠Sidach 30 Sep '06

30 Sep '06

Hello Michael and Paul, This one would have to be an external method since the external server doesn't offer XMLRPC. It's also made more difficult by the fact that ssl will have to be involved. I'm going hunting for a better way but I will certainly be using XMLRPC for some other functionality that's required. cheers and thanks, David
