Transaction sizes
by Paul Zwarts 16 Nov '00

Hi all, I have a few forms that really work intermitently. They are quite large in processing, accessing several thousand occurences in several tables, several times. Wont go into details, but its a resource hog. Alot of times the page eventually returns a No data error. This causes me to wonder if there are some kind of restraints on Zope in terms of its job size. Are there any tweaks to zope that I can fix this, or is it directly related to the resources of the server? Anyone with an idea? TIA, -- Paz Oratrix Development BV http://www.oratrix.com GRiNS SMIL Editor -

Dr.Watson on NT
by J�lio Dinis Silva 16 Nov '00

16 Nov '00

Hi all, Is there a NT guru in the house :-) Zope 222 Sometimes Zserver goes Zombie, I login on the machine and I see a DrWatson Window. I close DrWatson window and the process automagically restarts, and everything ok. Whenever this happens two logs are written in EventLogger: -one is a Warning: Restarting Zope... -one is a Info: starting Zope... With a couple of seconds of distance in time between them. I can see something is puting ZServer zombie and I'm looking at debug to find the sucker method :-) but this DrWatson behaviour never seen by me before: could be Zope doing a Zombie Timeout and restarting himself? If yes why does he hangs and only by closing the DrWatson Window the python.exe process really restarts? Any comments, tips, Dr.Watson Guru?

using if with date values
by Herring, William O. 16 Nov '00

16 Nov '00

I would like to insert into the this sql table the form variable birth.x. I would like to do it only if the date variable identification.birthdate is greater the that listed below. I know the current 'if' statement is incorrect and probably not even close. However, I haven't been able to find any documentation. Any ideas or solutions would be appreciated.  INSERT INTO inventory (x) VALUES (  )

The Parsed XML project is now public and ready for input. Parsed XML is the successor to XMLDocument. We have a wiki at <http://www.zope.org/Wikis/DevSite/Projects/ParsedXML>. zope-xml(a)egroups.com is also a good place for discussion at this time. -- Karl Anderson karl(a)digicool.com

RE: [Zope] ZClasses on top of my Python classes?
by Max Møller Rasmussen 16 Nov '00

16 Nov '00

From: Randall Kern [mailto:randy@teamkern.net] >I've seen several doc tidbits suggesting one create ZClasses derived from their >Python classes, sticking all the biz logic in the python classes, and the >presentation in the ZClasses... >Could someone provide some insight into why this is better than simply writing >separate python classes for logic and presentation? (Although I have to admit >hitting the "Restart Server" button every time I make a typo is getting old) Well one thing is that it clearly separates logic from presentation, and if you know zClasses it is easier to get started with while stille being nice to program in Python. You can reuse the same Python logic and give it several different interfaces in several zClasses. Regards Max M

modifying objectValues from an external method?
by Bowyer, Alex 16 Nov '00

16 Nov '00

You may remember I have posted a couple of times about problems I have had with manage_delObjects to delete a news article object from a news page which contains several child news article objects. I thought I would try and avoid the problem and make a Python method to remove the item. This method takes the list of articles (i.e. objectValues) and does the deletion on the parameter passed in. The problem I have is, objectValues doesn't seem to exist at Python level, only at DTML level. So instead of: <dtml-call "my_delete_function(objectValues)"> which is not valid, I have to use: <dtml-let my_list=objectValues> <dtml-call "my_delete_function(my_list)"> </dtml-let> The problem with this is that even though the parameter is passed by reference, the changes are only being done to my_list and not passed back to objectValues. So I lose them once my_list is out of scope. Can anyone suggest an alternative or a workaround? I thought about returning the modified list from the function, but DTML provides no functionality to set objectValues equal to this result. Any help would be appreciated!

Help needed with LoginManager and REMOTE_USER authentication
by Jay, Dylan 16 Nov '00

16 Nov '00

I want to use REMOTE_USER authentication so that I can authenticate people using IIS NT authentication intergration. IIS is set up and passing the correct REMOTE_USER to Zope. I set up LoginManager with a GenericUserSource. Now I figure I want anyuser that can pass the IIS security to be a user, ie no presistant list of users I want to check against. I figure I can do this by creating pythonMethods for userAuthenticate and userExists which both return 1. I did this but every time I try to access a page protected by the LoginManager I get the following error "Sorry AUSLABS\dylanj, you are forbidden to access this resource." saying that the GUF stuff is probably not working. Anyone with any ideas whats wrong or with a better way to do what I want? The problem I seem to have is that when I activate the GUF user source I lose management access to the LoginManager object. If its not working and therefore not authenticating me then shouldn't use aquisition to find a acl_user folder lower down to authenticate me and therefore let me use the management interface like normal?

zlib.error : huh?
by Aaron Straup Cope 16 Nov '00

16 Nov '00

I am trying to understand what exactly is going on when Zope returns an Error -5 page. Normally, this only happens on the left hand navigational menu but today it happened while I was expanding an xml document/tree object from the Examples package for the XML Document product. I've tried searching Google, the Zope site and the mailing list but to no avail. Could someone please explain what's going on here? Is it me? Is it Zope? How exactly do I prevent these errors from happening? Thanks, Error Type: zlib.error Error Value: Error -5 while decompressing data: [] Traceback (innermost last): File /usr/local/zope.old/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope.old/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope.old/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope.old/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope.old/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: tree) File /usr/local/zope.old/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: tree) File /usr/local/zope.old/lib/python/OFS/DTMLDocument.py, line 177, in __call__ (Object: tree) File /usr/local/zope.old/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: tree) File /usr/local/zope.old/lib/python/TreeDisplay/TreeTag.py, line 154, in render (Object: test[0]) File /usr/local/zope.old/lib/python/TreeDisplay/TreeTag.py, line 229, in tpRender (Object: Manageable) File /usr/local/zope.old/lib/python/TreeDisplay/TreeTag.py, line 637, in decode_seq zlib.error: (see above)

Uploading files
by Nolan Darilek 16 Nov '00

16 Nov '00

I'm trying to write a replacement form which allows users to upload images into a folder. I'm almost there, but not quite. I'm having difficulties getting the file contents into the database. I have an <input type="file"> field, and I'm fairly sure that the data is being sent. When I create the Image however, I use file=REQUEST['file'], and the resulting image stores the path to the file, instead of the file contents. So, given that I've uploaded a file, and that its name is in REQUEST['file'], how do I get at its contents when creating the Image?
