Hi Everyone. I am still running Zope 2.7.5. Will there be any problems if I jump directly to 2.9.2? Thanks, Dave

psycopgda
by Josh Stephenson 08 May '06

08 May '06

I recently installed psycopgda version 1.0.0 and restarted zope. I can see that it installed because it's listed under products in zope's control panel, but it's not listed in the drop-down menu where all the other products are. I installed by doing: python install.py build python install.py install Zope 2.9.2 Python 2.4.2 PostgreSQL 8.1.3 I've tried installing psycopg version 2-2.0b8, but I don't even get a listing in the products under zope's control panel. What am I doing wrong?

Hi Dieter, Thanks for your quick response and solution. It's a great relief to have it working OK for Firefox too!

First run TypeError
by David Pratt 08 May '06

08 May '06

Hi. I have been experimenting with making a hybrid storage for zodb. The storage seems to work well except that I am getting this error on the first request to the server and I am not exactly sure where it is coming from. Error Type: TypeError Error Value: unbound method method_descriptor object must be called with Application instance as first argument (got RequestContainer instance instead) When I refresh the browser, I get my login and no problems at all using the zope instance etc. The event and error logs are clean. But when I restart the server, the error appears on startup again. Many thanks. Regards, David

converting bytestreams from iso-8859-1 to utf-8
by Giuseppe Bonelli 06 May '06

06 May '06

Hi all, sorry if this is not zope specific, but can someone please explain to me the following behaviour when trying to convert an iso-8859-1 string read from a file to an utf-8 encoded one? s='\x93test\x94' #an iso-8859-1 string #\x93 and \x94 are left and right #double quotation marks, #as seen in a browser set to iso-8859-1 ss=unicode(s,'iso-8859-1').encode('utf-8') gives ss='\xc2\x93test\xc2\x94' which is wrong (as seen in a browser set to utf-8)! but: u=unicode(s,'iso-8859-1') u=u.replace(u'\x93',u'\u201C') #u201C is unicode left double quot mark u=u.replace(u'\x94',u'\u201D') #u201d is unicode right double quot mark ss=u.encode('utf-8') gives ss='\xe2\x80\x9ctest\xe2\x80\x9d' which is right (as seen in a browser set to utf-8)! Do I have to explicitly replace all characters above \x7F ? TIA __peppo

Btreefolder: How to fix Keyerror ???

problem opening pdf-files with firefox in LocalFS folders on Zope
by Marinussen, M.J. (Ria) 05 May '06

05 May '06

Hi, I've got Zope 2.8.5 installed with LocalFS version LocalFS-1-3-andreas on Solaris (SunOs 5.8, I'm not sure which version number of solaris that is...) When I place pdf-files in the LocalFS directories, sometimes they open correctly, but most of the time they open as text-file when using Firefox. With other browsers (Internet Explorer, Opera) this problem does not occur. In the directory-listing the files are all identified correctly as type "application/pdf". At first I thought that Firefox had problems with some documentversions of pdf, so instead of using version 1.6 I tried 1.2. But no luck. When placing the files in the zope db, and not in a LocalFS folder, Firefox has no problems with any of them, and just opens them fine. Does anyone have a clue what is going wrong here and even better, how I can solve this problem? Thanks in advance, Ria Marinussen

HTTP PUT
by David 05 May '06

05 May '06

Hi I need confirmation (mainly for some peace of mind, but also because reading google results, all sorts of questions from in my head). I have a user messing with a site using HTTP PUT to upload files. The user has access privileges to use a simple CMS (although for the time being now, they're revoked). Will switching off the permission for "WebDAV access" prevent any successful PUT or do we need to take further actions? We also allow FTP access to certain directories. Can this be abused to upload files elsewhere? Here's a log entry: 10.0.9.1 - potter [03/May/2006:17:02:02 +0100] "PUT /site/microsites/ harry/home/Home Page/page/add_block?block=1/ter_restrnt.jpg HTTP /1.1" 204 221 "" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: 1.7.12) Gecko/20050915" 10.0.9.1 - potter [03/May/2006:17:02:02 +0100] "PUT /site/microsites/ harry/home/Home Page/page/add_block?block=1/small_show.jpg HTTP/ 1.1" 204 221 "" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: 1.7.12) Gecko/20050915" 10.0.9.1 - potter [03/May/2006:17:02:03 +0100] "PUT /site/microsites/ harry/home/Home Page/page/add_block?block=1/small_c-exhibition00 31.jpg HTTP/1.1" 204 221 "" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915" 10.0.9.1 - potter [03/May/2006:17:02:04 +0100] "PUT /site/microsites/ harry/home/Home Page/page/add_block?block=1/College Logo.jpg HTT P/1.1" 204 221 "" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: 1.7.12) Gecko/20050915" 10.0.9.1 - potter [03/May/2006:17:02:04 +0100] "PUT /site/microsites/ harry/home/Home Page/page/add_block?block=1/page/Home Page HTTP/ 1.1" 204 221 "" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: 1.7.12) Gecko/20050915" Thanks for any help.

[Warning] "ManagableIndex" "Zope2.8+" incompatibility
by Dieter Maurer 05 May '06

05 May '06

WARNING! We hit an incompatibility of "ManagableIndex" with "Zope 2.8+". For Python new style classes, "__len__" instance attributes are no longer taken into account in the implementation of the "len" builtin. "len" now only looks for "__len__" class attributes. From "Zope 2.8+" on, all persistent Zope objects are instances of new style classes. Especially, "ManagableIndex"es are new style classes. "ManagableIndex"'s "__len__" instance attribute is no longer used by "len". Some Zope base class defines the class method "__len__" to return 1. As a consequence, "len" applied to a "ManagableIndex" always returns 1 in Zope 2.8 and later (until "ManagableIndex 1.3.1"). The badly behaving "len" can seriously confuse "AdvancedQuery" (and other similar query frameworks) that uses "len(index)" to guide the implementation of sorting. In our observed case, "AdvancedQuery" sorting was 3 to 5 times slower and read 3 times more objects than necessary. The bug is fixed in "ManagableIndex 1.3.1".
