Zope stalls indefinitely
by Leichtman, David J 04 Oct '00

04 Oct '00

Thought we had a problem of ours fixed, but here it is once again, a month later. Zope, every once in a while, will just stall indefinitely. The Zope process doesn't die, it just hangs. Everything was fine for a month or so, and now the problem's started again, about every hour. We're running 2.1.6 on Solaris with pgsql and the ZPyGre adapter and the most recent copy of FSSession. Any thoughts. I've posed this question to a lot of people many times. Now that it's back, I'm hoping for fresh insight.

client proxy setting
by TMGB 04 Oct '00

04 Oct '00

Can I get the user's client proxy setting using 'REQUEST' or some other syntax, product, or utility. This is not Proxy Roles or ProxyPass, but the client's proxy settings if any. I am working on a help page to debug a user's settings if he or she can't get to certain pages with our proxy server settings on their browser. I've found this to work for testing cookies acceptance:(set a cookie and then try to get it) <dtml-if expr="RESPONSE.setCookie('uname','test', expires= (ZopeTime() + (1.0/102.0)))"></dtml-if> <dtml-if "REQUEST.has_key('uname')"> YES, You Do Have Cookies Enabled <dtml-else> NO, Your browser is not accepting cookies </dtml-if> Thanx, Thomas -- -------------------------------------------------------------------- Rock and Rule Zope Rocks -- http://www.zope.org Python Rules -- http://www.python.org -------------------------------------------------------------------- Thomas McMillan Grant Bennett Appalachian State University Computer Consultant III University Library bennettt(a)am.appstate.edu http://www.library.appstate.edu/webmaster/ Voice: 828 262 6587 FAX: 828 262 3001 Windows 95 is a 32-bit extension to a 16-bit patch for an 8-bit operating system that was originally coded for a 4-bit microprocessor. - Chris Dunphy Boot Magazine

external method import error (ImportError)...
by Eric 04 Oct '00

04 Oct '00

Hi, To summarize: How do I import modules in an External Method's .py file? I have an external method that points to a .py file that has an import statement at the top. The import statement loads another module of mine (CProject.py). I've placed both files (pwToxml.py and CProject.py) in the Zope/Extensions directory. When I try to create an external method on the pTox.py file with the following parameters: ID = pTox Function Name = pTox Python Module File = pwToxml I get the following error: Error Type: ImportError Error Value: No module named CProject Traceback (innermost last): File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/Zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addExternalMethod) File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_addExternalMethod) File /usr/local/Zope/lib/python/Products/ExternalMethod/ExternalMethod.py, line 130, in manage_addExternalMethod File /usr/local/Zope/lib/python/Products/ExternalMethod/ExternalMethod.py, line 178, in __init__ (Object: pTox) File /usr/local/Zope/lib/python/Products/ExternalMethod/ExternalMethod.py, line 201, in manage_edit (Object: pTox) File /usr/local/Zope/lib/python/Products/ExternalMethod/ExternalMethod.py, line 210, in getFunction (Object: pTox) File /usr/local/Zope/lib/python/App/Extensions.py, line 217, in getObject (Info: ('/usr/local/Zope/Extensions/pwToxml.py', 'pwToxml')) File /usr/local/Zope/Extensions/pwToxml.py, line 1, in ? ImportError: (see above) I checked the sys.path for my Python installation and placed the CProject.py file there, but I still get the same error. Here's the top of my pwToxml.py file: import CProject, string def pTox(self, REQUEST): """Function to map pw to CProject Objects""" P=CProject.CProject() dictData = REQUEST.form.items() strTemp = "" strError = "Error Retrieving Dictionary Value" ...etc... Thanks for any help you can provide.

help! dtml-if question
by Dr. Anthony Monta 04 Oct '00

04 Oct '00

Hi, I've tried to find a solution myself but now am stuck. I created a little "Blurb" product for a university department website so that faculty members can announce recent publications on the department's homepage. They create these ZClass instances in their own folders, and a DTML method in the top-level folder grabs and displays them at random. (I want to avoid using ZCatalog for the time being.) What the method does is randomly choose a faculty folder, and then randomly choose a Blurb instance within that folder. Here's the hack I came up with: <dtml-with Dept> <dtml-with Fac> <dtml-with Sites> <dtml-with "_.whrandom.choice(objectValues(['Folder']))"> <dtml-with "_.whrandom.choice(objectValues(['Blurb']))"> <dtml-var index_html> (end tags omitted) The problem is that this method will produce an Index Error when it comes across a folder that doesn't contain an instance of "Blurb" class. So I need to make the selection of a folder conditional on Zope's finding a Blurb in that folder. Here's what I tried after reading up: <dtml-with Dept> <dtml-with Fac> <dtml-with Sites> <dtml-with "_.whrandom.choice(objectValues(['Folder']))"> <dtml-if "_.has_key('Blurb')"> <dtml-with "_.whrandom.choice(objectValues(['Blurb']))"> <dtml-var index_html> </dtml-with> <dtml-else> Some default Blurb would appear. This method fails. Can someone help?

Implementing a distributing mirror
by Luciano Caroti 04 Oct '00

04 Oct '00

Hi, I would like to implement a system to distribute PDF document. I would like to use ZOPE on 5 server distributed in Europe. I would like to build a system that send an email to a paying user where I put an URL. I would like that in URL I send temporary authentication information to allow access to a virtual directory where I put only documents or images files that user purchased. Have you any hints on how implement this architecture? Thank you in advance, Luciano Caroti.

why does squishdot url_quote email address values?
by Fred Yankowski 04 Oct '00

04 Oct '00

Version 0-7-2 of Squishdot seems to use the url_quote option when accessing the value of admin_address in particular, so when a DTML page has code like  and admin_address is a property with the value "foo(a)bar.com", the resulting HTML code is foo%40bar.com which doesn't work correctly, particularly when used as the value of a 'mailto:' URL. So what's the solution? Is Squishdot wrong to use url_quote this way? Why is url_quote hiding the "@" anyway -- I don't see any reason for escaping it this way. -- Fred Yankowski fred(a)OntoSys.com tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA
