FastCGI didn't use to need VirtualhostMonster???
by Simon J. Blandford 23 Jul '04

23 Jul '04

I couple of years ago I set up zope using FastCGI & Apache1 and all I needed in httpd.conf was the following... FastCgiExternalServer /var/www/html/zope -socket /tmp/zope.soc -pass-header Authorization <Location /zope> SetHandler fastcgi-script </Location> When I accessed the default web host e.g. http://localhost/zope I got zope. No need to set up Virtualhostmonsters or Siteroots in Zope. It just worked. All the links magically began with http://localhost/zope. That's why I really liked the FastCGI solution over using proxypass. Now, I try the same thing with Plone & Apache 2 (which should be the same in respect of Apache/FastCGI) and all the links just begin with http://localhost. Can someone please tell me what changed between then and now. Is it Apache, FastCGI or Zope? Also, is there anyway I can get this system to work again without resorting to unsightly Virtualhostmonsters? Sorry I can't remember the exact versions of applications I was using. I think Zope 2.4 had just come out and I was using Apache 1.3.x. Today I am using latest releases with Apache 2.0.x. Thanks, SimonB

I think I have a memory leak. After 7 days I have a memory consumption of 300MB. I have the following debug infos: Class July 14, 2004 9:06 am July 15, 2004 12:16 pm Delta DateTime.DateTime.DateTime 1417 6363 +4946 Products.PageTemplates.Expressions.SubPathExpr 2513 7059 +4546 BTrees.OOBTree.OOBTree 214 3724 +3510 Acquisition.ImplicitAcquirerWrapper 369 3677 +3308 Products.PageTemplates.Expressions.PathExpr 1168 3275 +2107 OFS.Image.Image 30 1458 +1428 Persistence.PersistentMapping 338 1629 +1291 It seems like I have leaking DateTime objects in some PageTemplates. How can they happen? I have the SimpleBlog product under suspicion. Thanks for every help. Regards, Florian Schulze

RDFSummary issue
by David Chandek-Stark 23 Jul '04

23 Jul '04

I'm having an odd problem with the RDFSummary product, although I'm not sure that the problem is with the product itself. It appears that either this product or a Python XML parsing function is converting "&" into "&", instead of "&". Browsers don't seem to mind, but Zope's TAL parser evidently doesn't recognize "&" as an entity (not that it should), and so escapes the ampersand on output. Since tal:attributes doesn't support a "structure"-like operation, I had to write a custom script to produce links for my RSS feed. Anyway, I'd like to know where this incorrect conversion is happening so I can address it appropriately. Thanks!

Error setting a session variable
by Norma Silva 23 Jul '04

23 Jul '04

Hi everybody, I'm new to this group. I got the very strange error below while setting a SESSION variable. Cannot understand why, because it says it is a SQL error. Site Error An error was encountered while publishing this resource. _mysql_exceptions.NotSupportedError Sorry, a site error occurred. Traceback (innermost last): Module ZPublisher.Publish, line 163, in publish_module_standard Module Products.PlacelessTranslationService.PatchStringIO, line 45, in new_publish Module ZPublisher.Publish, line 108, in publish Module Zope.App.startup, line 226, in abort Module ZODB.Transaction, line 134, in abort Module Shared.DC.ZRDB.TM, line 63, in abort Module Products.ZMySQLDA.db, line 327, in _abort NotSupportedError: (1196, "Warning: Some non-transactional changed tables couldn't be rolled back") ---------------------------------------------------------------------- Thers is no entry on the error log for more information. I'm running zope 2.7.0 and also tried on 2.7.2-0. Both gave me the same error. The python script code is: request = container.REQUEST session = request.SESSION ## request.set('caller', 'processItem') if not request.has_key('submit'): return 'NO SUBMIT' # orderNo = session['orderNo'] if orderNo == 0: orderNo = context.createOrderHeaderPY() session.set('itemIndex', 1) session.set('orderNo', orderNo) ## <-- LINE WITH PROBLEM itemIndex = 1 else: itemIndex = int(session['itemIndex']) + 1 session.set('itemIndex', itemIndex) orderNo = session['orderNo'] # I tried setting up another SESSION variable (using a different name for it) and it works. This code was working before. It broke when I made some changes in other scripts. I'd appreciate any help. Thanks, Norma

in Properties, how to assign values to multiple selection property
by Gary Zhu 22 Jul '04

22 Jul '04

I am trying to add a multiple selection property from the ZMI properties tab. Not sure how to set the name and value pair for each option. Only the name part work, when I set the value of the multiple selection property to another lines property or tokens property. I'm trying to get this: <option selected>Name</option> to this: <option value="21" selected>Name</option> TIA

Login problem
by Liz Marlow 22 Jul '04

22 Jul '04

I'm using zope 2.6.2b5 and I'm having trouble logging on (using exUserFolder). After entering user name, password, and hitting submit - the screen redirects back to the login screen with no error statement about bad user name or password. I'm only getting the problem on one of my installs - it used to work just fine but suddenly stopped! I don't think anything has changed on the machine. Anyone got any ideas? Many thanks Liz ________________________________________________________________ Sent via the WebMail system at rcsltd.co.uk

backbutton and form selections
by Erik Myllymaki 22 Jul '04

22 Jul '04

I just migrated from Zope 2.3.2 on NT to Zope 2.7 on Win2k. I have a lot of pages where many selections are made (checkboxes) and then submitted to use a SQL method and create a report. On the old setup, hitting the back button would take me back to the form page with all the form selections/de-selections remembered. Now, this works with Mozilla but no longer with IE ? Any ideas?
