Mime type for PDB files
by Alan 02 Nov '06

02 Nov '06

Hi List! I have some lines in a ZPT file creating a link to PDB files in a LocalFS folder: <span tal:repeat="item python: options.get('pdbsw','null')"> <tr><td> <a tal:attributes="href python: container.JOBS.absolute_url()+'/'+item+'.pdb'" tal:content="python: item+'.pdb'">get file</a> </td><td> </span> It works fine expect for one thing. When clicking at the link, my browser (Safari), thinks my PDB file has mime type text. Is it possible to define the mime type (chemical/x-pdb) for my linked files in Zope? I would thank any attention in advance.

newbie root addressing questions
by Terry Brown 02 Nov '06

02 Nov '06

I'm buidling a site in /site/collected on a Zope system. Using ZPT rather than DTML So every page starts with <html metal:use-macro="root/site/collected/tmpl/basepage/macros/page"> also, for the time being, the site's at someurl.com/collected/, but in future might be someurl.com/ so pages include things like <link href="/collected/collected.css" rel="stylesheet" type="text/css"/> so I'm wondering 1) how I can make the site relocateable on the Zope system, i.e. each file has 'root/site/collected' in the initial macro call, can that be avoided, and 2) how can pages refer to their site's root when that is currently /collected/ but might later become / ? I found some discussion of DTML approaches, but I'm hoping for something purely ZPT. For (2) the main problem seems to be that if I put the root path (/collected/ or /) in /site/collected/rootpath it's hard to find from /site/collected/gallery/ or /site/collected/gallery/page1/ or some other sub-sub-location. Thanks,

External Method = Slow; Shell Script = Fast
by Edward Pollard 01 Nov '06

01 Nov '06

Hello, I've got an external method that does some pretty complicated stuff. Basically it takes two XML files - one defines constraints, the other variables - and the script finds a solution using the variables that satisfies the constraints. At the command line (or executed via an external method that calls a shell script) execution is 2 seconds. As an external method execution is 15-20 seconds with the same input. Can anyone offer tips or strategies to improve performance? It would be obnoxious to have to encode objects for passing to a shell script. --- Edward J.

[Zope] Zope 2.6.4 -> 2.10.0 Migration (PageTemplates, Unicode, etc.)
by Brian Brinegar 01 Nov '06

01 Nov '06

So... We decided to move from Zope 2.6.4 to something newer (currently targetting Zope 2.10.0). I immediately found that none of our PageTemplates work we get an error on PageTemplates/Expressions.py line 92 that call_with_ns is not defined. ob = call_with_ns(ob, ns, 2) Changing it as follows fixes the problem, I think this is a bug. ob = ZRPythonExpr.call_with_ns(ob, ns, 2) Next... we have lots of PageTemplates which raise the following exception: Module zope.pagetemplate.pagetemplate, line 118, in pt_render Module StringIO, line 271, in getvalue UnicodeDecodeError: 'ascii' codec can't decode byte 0xb9 in position 93: ordinal not in range(128) I suspect there are non-ascii characters in the file, but I'm not sure how to fix this, or how I would know what to replace it with. Is there a way to turn off Unicode support? Any other issues I might run into during this upgrade? Should we move to an older version (2.8? 2.9?) first and then onto 2.10?

invalid load key
by William Heymann 31 Oct '06

31 Oct '06

This is the traceback I am getting when I try to pack the db Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module App.ApplicationManager, line 426, in manage_pack Module ZODB.DB, line 605, in pack Module ZODB.FileStorage.FileStorage, line 1348, in pack Module ZODB.FileStorage.fspack, line 482, in pack Module ZODB.FileStorage.fspack, line 228, in findReachable Module ZODB.FileStorage.fspack, line 304, in findReachableAtPacktime Module ZODB.FileStorage.fspack, line 377, in findrefs Module ZODB.serialize, line 625, in referencesf UnpicklingError: invalid load key, '^\' How can I find out what object is damaged so I can fix it/remove it? My best guess on what caused the problem was undoing a large set of deletes because someone deleted something they should not have and then deleting those objects again. I tried to run fsrecover.py on the db and it seems to just spin at around 99%. I will run it again and just leave it running and see if it ever finishes but I let it run for a pretty long time already. Also any idea on what could have really caused the problem? memtest did not report any errors when I last ran it and the hard drive diagnostics don't report any issues either. The Zope version is 2.9.5 and the db is about 2GB in size and the point at which fsrecover.py stalls is about the last 4 megs. Thanks
