assign REQUEST object to redirect?
by Ferhat Ayaz 09 Sep '06

09 Sep '06

Hi, If I return n Script (Python) the following container.REQUEST.form['id'] = 1 return context.index_html(container.REQUEST) then I have access to request/form/id within the page template index_html. Now I must redirect instead of returning like return container.REQUEST.RESPONSE.redirect('index_html') But how can I give request object in a redirect. Don't suggest the way appending the query string with 'index_html?'+form fields ... Thanks, Ferhat __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Hanging site
by David 09 Sep '06

09 Sep '06

Hi I have a problem with a site running on Zope 2.7.5. After a restart the site serves request happily for a while and then hangs, meaning: - The server processes are still alive (I can see them with ps) - New attempts of page views do not show in the Z2.log - Browser just reports time out (not that the site is not available) - DeadlockDebugger does not respond either There is no recognisable pattern looking at the last requests in the Z2.log before the site hangs. The last requests are mostly just view requests of pages, which display fine after a restart. I've tried packing the ZODB (which worked fine, but did not resolve the issue). I've run the fsrecover.py, but that didn't seem to find anything. I have moved the Data.fs to another machine where I have a Zope 2.7.8 and tried some tests there, but again couldn't find anything pointing towards a possible source of the problem. I have now enabled the event.log and got this entry on the last "hangup": 2006-09-06T19:44:34 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 212.96.102.29:3207 at 0x9c0326c channel#: 149 requests:> (exceptions.ValueError:HTTP headers invalid (too long) (got: 8760 bytes, allowed 8192 bytes [/sw1/packages/python235/lib/python2.3/ asyncore.py|read|69] [/sw1/packages/python235/lib/python2.3/ asyncore.py|handle_read_event|390] [/sw1/packages/python235/lib/ python2.3/asynchat.py|handle_read|148] [/sw0/sbzope_3_2/lib/python/ ZServer/HTTPServer.py|collect_incoming_data|378]) But I don't really understand what it means. Any help or suggestions welcomed! Thanks DR

hello andreas, am hereby giving the trace from log file. other than LDAPUF we r not using any other 3rd party products. what i want is just to get basic authentication popup dialog to come. if it comes then the problem will be solved i guess. is there a way to configure the application so that the popup dialog pops up when the application is accessed ? coz the error mesg is that its trying find user Anonymous in LDAP and not finding. if popup comes then it may pass the entered username/password to LDAPUF i guess. I have not yet tried migrating by just copying the Data.fs file. i'll try it out soon. till now i hv tried using import/export. please help. thanks and regards -yogeen trace : 2006-09-08T14:38:52 ERROR Zope.SiteErrorLog http://systemIP:8080/isac/PGA/index_html 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 OFS.DTMLDocument, line 128, in __call__ - <DTMLDocument at /isac/PGA/index_html> - URL: http://systemIP:8080/isac/PGA/index_html/manage_main - Physical Path: /isac/PGA/index_html Module DocumentTemplate.DT_String, line 476, in __call__ Module OFS.DTMLMethod, line 137, in __call__ - <DTMLMethod at /isac/PGA/cl_index_html> - URL: http://systemIP:8080/isac/PGA/cl_index_html/manage_main - Physical Path: /isac/PGA/cl_index_html Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_Let, line 75, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: cl Module <string>, line 1, in <expression> Module DocumentTemplate.DT_Util, line 160, in render Module OFS.DTMLMethod, line 137, in __call__ - <DTMLMethod at /isac/PGA/cl/areYouCLpaRecoSanc> - URL: http://systemIP:8080/isac/PGA/cl/areYouCLpaRecoSanc/manage_main - Physical Path: /isac/PGA/cl/areYouCLpaRecoSanc Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_Let, line 76, in render Module DocumentTemplate.DT_Let, line 75, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: _ Module <string>, line 1, in <expression> AttributeError: findUser --- Andreas Jung <lists(a)zopyx.com> wrote: > > > --On 8.

Re: Change language with PTS

Hi Chris, > Don't use PTS! Only if using zope < 2.8.x, which indeed I'm using, for we have a 3rd party product that depends on that.

I searched that thread and the references there helped me a lot with my small example. Google even now how to spell your last name ;-), but I don't. Anyway, for the interested here is the thread: * Zope 2.9 and Zope 3 i18n, more questions... http://mail.zope.org/pipermail/zope3-dev/2006-June/019496.html The article by Philipp von Weitershausen, which is mentioned in there, is really useful. The examples of his website are even better. I'm not the OP, jet I would be also interested in your product. I'm not planning to use the zope3 translation yet, but I want to experiment a little bit.

Zope hands when database takes too long to respond
by Sinang, Danny 08 Sep '06

08 Sep '06

Hello, We wrote an application (on Zope v2.7.6-final) that queries a MySQL database via ZMySQLDA v2.0.8. Whenever the MySQL server experiences heavy load, Zope seems to hang, such that we can't even access the ZMI. Is this a bug in version 2.7.6 or ZMySQLDA ? Or are there some settings I can tweak to adjust some database connection timeout value ? Regards, Danny

Authentication Problem with migration from Zope 2.6.1 to Zope 2.9.4
by yogeen honnavar 08 Sep '06

08 Sep '06

Dear users, we have a zope application on an older system running Redhat 7.2 and Zope 2.6.1 with python 2.1. Now we wish to migrate the application to latest stable relase of zope 2.9.4 with python 2.4.3 we hv installed zope 2.9.4 and imported the application through .zexp file. this application uses LDAPUserFolder for authenticating against an LDAP server. After importing the application we recreated LDAPUserFolder instance as per the instructions. Now the problem is, when we access the application the Authentication pop-up dialog is not coming up and the application is trying to search the LDAP directory for Anonymous user and since the user does not exist in LDAP it is returning error Error: findUser. In the old zope server basic authentication dialog pops up when we access the URL. Can anyone suggest how to solve this problem ? How to configure the application as protected resource(we are using the built-in ZServer) so that authentication dialog pops up when the URL is accessed ? any help would be greatly appreciated. Thanks and Regards -Yogeen Honnavar __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

tal assignment
by David Bear 08 Sep '06

08 Sep '06

I wanted to assign a list object to a tal global variable but I can't seem to find the correct syntax. I tried: <div tal:define="global mylist=['item1', 'item2']" tal:content=""> blah </div> but it doesn't like that syntax. Googling turns up thousands of items that deal with tal but I can't see a simple example of assigning a list object to a variable name. -- 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"

Need help tracing my application errors.
by Jose Carlos Balderas Alberico 07 Sep '06

07 Sep '06

Greetings. I have a problem with an application we have hosted in Zope, and I thought you could give me a hand. Basically, my question is: what's the easiest way to trace errors raised by a python script that's part of the application? This is the exact situation: I have to modify such application. It is a very big application, with a lot of python scripts, sql methods, etc... After testing it for the first time after the modification, nothing happens. By this I mean there is no error message, yet I know the application doesn't work right, since no data were inserted into the database. If it was an application developed in some other language, I'd just print messages on the screen to carry on with the debugging, and be able to know where the application is going. But this doesn't work with Zope. I just can't write "print 'some message'", because nothing gets written on the screen... I have tried with the Error_log object, but since the python script doesn't raise exceptions, no exceptions is captured by such object. I'm out of ideas here. What I basically want is some way of printing stuff somewhere, maybe a file, or the screen itself, to know where the application is in every moment. That way, locating the error would be far easier. Please, any help with this will be highly appreciated. Thank you very much in advance.
