Corrupt Data.fs
by Michael Kaplan 29 Apr '05

29 Apr '05

Hi, I just found out that my Data.fs is corrupt. Zope is still running, and restarting but I'm getting POSKeyErrors if a want to see folder contents and so on. I tried to follow the advice in http://www.zopelabs.com/cookbook/1095965033 (I use Zope-2.7.4) but end up with >>> obj=root.unrestrictedTraverse('/folder') Traceback (most recent call last): File "<stdin>", line 1, in ? NameError: name 'root' is not defined what's wrong here? Therefore I used fsrefs.py and got information like oid 0x030571 Products.CMFCore.ActionInformation.ActionInformation last updated: 2005-03-14 08:20:34.643177, tid=0x35BE85493CF9666L refers to invalid object: oid 0x0304fa object creation was undone: 'Products.CMFCore.Expression.Expression' For this oid I get > python Python 2.4 (#1, Jan 14 2005, 00:24:33) [GCC 2.95.3 20010315 (release)] on sunos5 Type "help", "copyright", "credits" or "license" for more information. >>> from Zope.Startup.run import configure;configure('/etc/zope.conf') >>> from Zope import app >>> from ZODB.utils import p64 >>> from ZODB import POSException >>> app = app() >>> obj = app._p_jar[p64(0x030571)] >>> print obj.getId() view >>> print obj.bobobase_modification_time() 2005/03/14 09:20:34.643 GMT+1 >>> print obj.meta_type simple item >>> print obj.__ac_local_roles__ None Could anybody tell me, how I can delete this object from Data.fs? Will obj.manage_delObjects(id) do the job for me? What parameters do I have to give to the programm? Thanks a lot in advance Michael

Unable to login to zope management interface on Ubuntu
by Vishwas Narendra 28 Apr '05

28 Apr '05

Hi, I'm running Ubuntu (warty). I just installed zope 2.6.4-1.1 through synaptic. I created a user with the "zpasswd inituser" command. I could connect to the zope server on port 9673. The zope quick start page comes up. When I click on the management interface link, I'm asked to enter the username and password. Even after I enter it correctly (the same values that I entered through zpasswd), I keep getting the same dialog box over and over again and I'm not able to proceed beyond this stage. Where am I going wrong? Vishwas.

Session Variable Error
by Asad Habib 28 Apr '05

28 Apr '05

I have a session variable called 'undergraduateProjectsDirected' that I declare using the following syntax: <dtml-call "REQUEST.SESSION.set('undergradProjectsDirected', [ ])"> When I try to append items to this list variable, I get the following error: AttributeError: 'NoneType' object has no attribute 'append' I know for a fact that this variable exists since flushing the SESSION attribute of the REQUEST variable using <dtml-var "REQUEST.SESSION"> yields its name and shows that it is initially empty. I am using the following statement to append items: <dtml-call "(REQUEST.SESSION.get('undergraduateProjectsDirected')).append([student_name, description])"> The strange thing is that when I change the name of this variable to 'undergradProjectsDirected', the error does not occur anymore. Has anyone experienced something similar? I think a variable with the same name exists (perhaps I created one in another one of my intranet applications) and Zope is referring to the old copy instead of the newly created one. I tried flushing the transient object container as well but it did not make a difference. Any help would be greatly appreciated. Thank you. - Asad

Or apt-get install zope2.7. Apt has packages for both 2.6.x (apt-get install zope) and Zope 2.7.x (apt-get install zope2.7).

Forcing all Zope access to come through an Apache/SSL proxy
by Reuven M. Lerner 28 Apr '05

28 Apr '05

I've written a Zope application that needs to be behind SSL. I assumed that the most straightforward way to do this would be to (1) set up Zope on port 8080 and (2) use Apache to act as a proxy between the outside world and Zope. Unfortunately, while it was a piece of cake to set up a proxy for non-SSL access to Zope, I'm rather stumped regarding SSL. I've done non-SSL proxying for years with mod_rewrite, and it was really a snap, so I'm surprised that this is so difficult. Zope is working just fine when I access it directly (using HTTP) on port 8080. I have installed the (self-signed) SSL certificate into Apache without any trouble, and am able to access individual documents on disk via SSL, using Apache. So if all I would want is to use Apache with SSL, I would be done by now. Here is the relevant portion of the Apache configuration file (with names and numbers changed somewhat): <VirtualHost 66.123.23.17:443> ServerName myserver.com ServerAdmin reuven(a)lerner.co.il SSLProxyEngine on RewriteEngine On RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/https/myserver.com:443/app/$1 [L,P] </VirtualHost> The above should make it possible (I believe), an HTTPS connection between my browser and my cup. Apache should then take that incoming SSL request and issue its own request to the Zope server. Zope will respond, sending it back to Apache, which (in turn) sends it back to me. But of course, that doesn't happen. Zope's provides indicates that many of the requests begin with "\x80g\x01\x03". My guess is that the SSL request is being piped to Zope directly, but it's hard to know from just a few characters. Does this mean that I need to do some more translating, from HTTP into HTTPS? Not that it should make any difference, but I'm running Apache 2.0.52 on Red Hat Enterprise 4.0, with Zope 2.7.5 and Python 2.3.4. Thanks in advance for any advice you might have, Reuven

External Method file generation Vs MSIE
by calisp＠gmail.com 28 Apr '05

28 Apr '05

Hi All, I have an external method that generates files - zip, pdf and xls. I would like the browser to present a file open/save dialog box and, depending on what the user clicks, open or save the file. Also, I want to be able to set the file name. Sounds simple enough and with most browsers setting the Content-type appropriately and the Content-Disposition to "attachment; filename="whatever"' works. I have not been able to get Internet Explorer to work properly though. Has anyone got this working? If so, how? Here is a full run down of the problem... I believe Internet Explorer uses a combination of the following to decide what to do with a file: o The Content-Type header. o The Content-Disposition header's value. o The Content-Disposition header's filename attribute's extension. o The extension of the external method. o The first part (200 bytes?) of the file contents. o The phase of the moon. (well, perhaps not, but it's starting to feel like it.) It then does one of the following: o Displays the file inline in the browser. o Displays the file open/save dialog. Clicking the save button saves the file. Clicking the open button launches the application that is associated with the file type IE has assumed the file to be but that application gives a file not found error. o Displays the file open/save dialog. Clicking on open or save displays another file open/save dialog. Clicking the save button again saves the file. Clicking the open button again launches the application that is associated with the file type IE has assumed the file to be but that application gives a file not found error. The filename of the file saved or the suggested filename when saving a file being viewed inline is sometimes the filename attribute in the content-disposition header and sometimes "external_method?query=string.ext". I have tried various combinations of the following: o Setting the Content-Type header to the file type, application/octet-stream, application/x-force-download, etc o Not setting the Content-Type header. o Setting the Content-Disposition header to inline, attachment and download with and without a filename attribute. o Not setting the Content-Disposition header. o Naming the external method filename.ext where ext is zip, pdf or xls as appropriate. o Hard coding the settings in the external method and not using a query string. Despite all this I have completely failed to get MSIE to behave in a sane manner and would greatly appreciate any advice anyone has on the matter. With thanks, Calisp

Re: [Zope] Which sound I learn?
by Cliff Ford 28 Apr '05

28 Apr '05

I produced a heavily customised site with Zope 2 that I am currently rebuilding in Zope 3. Even so, I feel hesitant to advise. I guess, with the advent of Five, then Zope 3 is the way to go if you are familiar with Python and xml. There are two recent, good Zope 3 books you can work through. I have found learning how to do things that are not in the Zope 3 books time-consuming, fortunately not an issue for me, but I think it will all work out with less code that is easier to maintain.

problems rendering objects stored in the local file system
by Dennis Allison 28 Apr '05

28 Apr '05

I am having trouble figuring out how to get Zope to access and render html and images files properly in the following context: In the local file system (that is, the Linux file system to be explicit) I have a collection of directories each containing an index.html file consisting of HTML and a collection of image files (*.jpg, *.gif, *.swf) referenced by the HTML. From a DTML object in the ZODB, I want to render the index.html and have it properly access the local image files. Calling the file "index.html" may be a bad name choice because it may be interpreted especially. In fact, what I really would like to be able to do is to reference all files relatively and allow internal directories and the like. We've been using the LocalFS product, mostly with great success, but this has got me stumped.
