ObjectManager FTPlist - acquisition issues
by Chris Price 28 Nov '01

28 Nov '01

I don't know if this the right place to ask these questions... I somewhat think that this belongs more in the zope-dev list but I'm hesitant to post there since I'm not officially a developer of Zope. There is a problem in the manage_FTPlist method of ObjectManager. I found a patch (written by Deiter Maurer and available at: http://www.dieter.handshake.de/pyprojects/zope/#bct_sec_5 ) that might fix this issue, but I'm uncertain as to the status of this patch. I'm not expecting anyone to solve this for me right away, but I would like to know what the right forum is to discuss this, who is the maintainer of this code, how to monitor the status of it, etc. I would also like to know what the status of Deiter's patch is; is it scheduled for inclusion in a future release of zope? Is it a potential security hole? If there is some place that I can go to find this information, could someone please let me know where? Here is a more detailed explanation of the problem: There is a bit of code in ObjectManager.py where it checks to see if an object is acquired: ob=self while 1: if App.Common.is_acquired(ob): raise ValueError('FTP List not supported on acquired objects') if not hasattr(ob,'aq_parent'): break ob=ob.aq_parent Now I'm not completely familiar with the inner workings of zope, so I'm not sure I understand how this is supposed to work. What I do know is that a ZClass that is nested inside another ZClass in the Products folder will cause problems with this bit of code. If you FTP into your ZServer and do: cd Control_Panel/Products/SomeProduct/SomeZClass/propertysheets/methods cd NestedZClass/propertysheets cd methods then the "ValueError" above will be raised. The while loop runs 3 times, with 'ob' being set to the following three objects: <ZClassMethodsSheet instance at 8942708> <bar_ZPropertySheetsClass instance at 88e3a58> <ZClass instance at 886c320> The ZClass instance then passes the 'is_acquired' test, the ValueError is raised, and the FTP server says 'No such directory'. So is the acquisition check just overkill? If it is removed, will that solve the problem? Or is the problem actually related to the fact that the <ZClass instance> passes the 'is_acquired' test when it should not? My apologies for getting so deep into this issue on the list here, but I just don't know where else to address my questions to. This problem is crippling FTP access to my development tree, and that is a critical factor in whether or not my company chooses to use Zope or not, so I would really like to get to the root of this problem. thanks for any info you can provide! chris price

import paths
by Scheck, Garth 28 Nov '01

28 Nov '01

I am trying to create an external method in Zope that links to a method in a Python script called "db." The Python script "db" imports another Python script I created called "GDAC". Both Python scripts are located in the Zope site's Extensions directory. When I try to save the changes on the external method I get an import error saying that it cannot find module "GDAC." Should GDAC be located in a different directory? What is the search path for imports within Zope? NOTE: This script works fine in PythonWin. Thanks, Garth

RE: zope - webalizer

Thats OK, what is not working? I don't use Eudora so I am not sure I can help you, the list is your best bet... -----Original Message----- From: Vid Bijelic [mailto:zoops4@yahoo.com] Sent: 28 November 2001 21:12 To: Norman Khine Subject: RE: zope - webalizer Hi Norman, First thanks on very detailed explanation. I set a cron job and webalizer to include logs only for /vid/website1 I used IgnoreURL * IncludeURL /vid/website1 I try with n domainname.com but it did not worked, so I use webalizer.config file with above setting. It is giving me stats now only for website1, I assume I could get much better results with Virtual Host product, but I have never try using it. By the way, I will post this on the Mailing list too. When Eudora users receive e-mails sent using Zope MailHost product, they got it all wrong. If I send HTML formatted text they got it as a plain text, if I attach PDF file they got it as bunch of gibberish. I try different type of encoding and nothing helped. Every other e-mail client receives it correctly.

i want a timeout interrupt
by Horst Wald 28 Nov '01

28 Nov '01

Hi, can one interrupt the execution of a script when a certain amount of time has passed? What I want to do: - I start with a given URL. - Then I read the webpage denoted by it into a string like page=urllib.urlopen(URL).read() and if it satisfies a given condition (e.g., it contains a certain word), parse it to find out all the urls it contains. - With these new urls I continue - I take care not to read the same URL twice This works fine in general, but there are certain web pages that never respond. If you try view them with a browser you get a timeout after a few mintues. But the urllib.urlopen() script keeps waiting until it gets a response and if never gets one, the whole program is stopped. What I would like now is to interrupt the script an return '' if it gets no response after 10secs. Any idea???

Passing a Variable from PHP
by Ben Ocean 28 Nov '01

28 Nov '01

Hi; I need to pass a variable from a php script (served by Apache) to a Zope script (served by ZServer). I can't do this as a hidden field in a form since there is no *form* on the php script: indeed, the user never notices the script as it doesn't generate any html. This is a randomly generated variable. How do I communicate it? TIA, BenO

Derivation from DTML document
by Tille, Andreas 28 Nov '01

28 Nov '01

Hello, I'm planing to write a new ZClass derived from DTML Document. The initialisation of an instance of this ZClass (MyDocument for instance) should contain the selection of some certain keywords, which would be added in the meta tags of the resulting html output. I just want to make sure that there is no such thing I'm looking for and that I will not reinvent the wheel. Kind regards Andreas.

How to deal with cookies??
by Robert Rottermann 28 Nov '01

28 Nov '01

Hi there, in a Python script I create a cookie that has as data a list with dictionaries. When I read that cookie back, this list is a string. My question: Is there an easy way to change that string back to a list of dictionaries. Eval et al are disabled in scripts. Robert

How to change values in tiny table
by Clark OBrien 28 Nov '01

28 Nov '01

Can anyone tell me how to update the data in a squishdot table after changing the dtml file. I don't care about dynamic update at this point but I just want to see the changes I have made with my editor. more explanation I am trying to edit the default squishdot screen which uses tinytable. the screen depends on dtml files under squishdot/demo/rightbox_methods for instance. I change these methods and the changes do not appear in my current squishbox instance. If I add a new squishbox the changes are seen. Clark

Re: Generating thumbnails on the fly using PIL
by Pieter Claerhout 28 Nov '01

28 Nov '01

Hi all, I got quite a lot further now. Here's the script I have so far: import PIL.Image import os.path import cStringIO def MakeThumb(self, image, width, height): oriImage = getattr(self, image) oriFile = cStringIO.StringIO(oriImage.data) image = PIL.Image.open(oriFile) image.thumbnail((width, height)) thumbnailImage = StringIO() image.save(thumbnailImage, "JPEG") thumbnailImage.seek(0) return thumbnailImage.getvalue() this all works find if you use it as: <dtml-var "PHTO_MakeThumb('AB_action_inbox.jpg', 160, 120)"> As soon as you want to do something like: <dtml-var "PHTO_MakeThumb('/images/AB_action_inbox.jpg', 160, 120)"> you get an AttributeError. Does anybody has a way around this? Cheers, Pieter

Help! Cataloging Numbers with ZCatalog
by abg＠comco-inc.com 28 Nov '01

28 Nov '01

Hi, I've run into an issue with ZCatalog. When indexing a page, ZCatalog appears to disregard number-only entries. In other words, "m4" will be cataloged, but "4" will not. For my purposes, it is very important that I be able to query the PrincipiaSearchSource for number entries. Please tell me that there is a way to enable this feature. Thanks, Aaron Gillette
