External Method and XML-PRC (Maybe a bug)
by Phani Kumar Arava 10 Jan '07

10 Jan '07

Hi, Iam trying to use Zope as an App server (basically to provide an XML-RPC interface) for a certain application . I have a function called addFile in the External Method. def ext_addfile(self): ob=self.Files ob.manage_addFile("hello","hello") I created an external method call ext_addFile() Now I write my client using xml-rpc lib s=xmlrpclib.Server("<hostname>") s.ext_addFile() And this adds a file to my directory. This freaked me out. Because i was anonymous user and this shdnt happen. The next thing i did was create a python script of the same structure and called it addFile() ob=context.Files ob.manage_addFile("hello","hello") Now I run my client xml-rpc program s=xmlrpclib.Server("<hostname>") s.addFile() and its fiving me unauthorized as expected. So basically i dont know why is this happening. Is this due to some permission problems i have on the directory or External Methods, or something which iam totally missing. -- Phani Kumar Arava Grad Student 1560 Worthington Street Department Of Computer Science Columbus Ohio 43201 2015 Neil Avenue Ohio State University Columbus Ohio-43210 Contact: (614)-286-2618 URL : www.cse.ohio-state.edu/~arava/ mailto: arava.3@osu.edu,phani.arava@gmail.com, arava_phani(a)yahoo.com

Recovering from Data.fs
by Rowan Woodhouse 09 Jan '07

09 Jan '07

Hi, I'm trying to recover a zope instance from a hardware failure. The only thing I have left is the backed up Data.fs file. I'm not entirely sure which version of Zope was used but I think it was 2.9 (certainly not 3), or what the install paths were for the instance or zope. When I try and use the backed Data.fs in a new zope instance I get the following error: Site Error An error was encountered while publishing this resource. Error Type: AttributeError Error Value: __getitem__ >From my understanding the paths for the zope instance have to be the same for Data.fs to work correctly. Is that correct? If so how can I determine what version of zope was being used and what the paths were for the backed up Data.fs? Thanks in advance, Rowan

Sorry Andreas.. My product is rewritten in python placed in the product folder. So yes, it is a instance of a class. In the future, I will be storing more data into one instance from other dbase file (The total columns may vary). I'm still in the developing stage and this is just a test run to know that is the length of processing time I'm look at. I want each entry to be an instance because I'm planning to create other interactive functions (edit and query(ZCatalog maybe, I'm not sure yet) and more ) for particular info. I've never thought of using a BTree because I don't know enough about it. I'll look into it but will BTree still be a better choice than making instance if I'm going to make interactive functions?

That means its going to take 50 ~ 60 minutes for 110000 entries. You're creating 110k instances for storing a string and two floats? If yes, that's stupid idea. You can persistent large amounts of data within a single instances by using Zope BTrees. > It not every day that you have to process over 110000 data entries but > processing over 60 minutes is still kind of long. > What kind of processing? -aj __________________________________________________ Do You Yahoo!?

need advice on mass data processing
by Allen Huang 09 Jan '07

09 Jan '07

I have a data file that has over 110000 entry of 3 column data (string, float, float) currently I have written my program so it will do an entry by entry processing with zope. This operation is like this 1. read data (the data file) 2. create product (a python product that store three field data: one string and two float data) 3. update product (update the three field entries) when I first tried it out with the first 1000 entries it took about 30 seconds. That means its going to take 50 ~ 60 minutes for 110000 entries. It not every day that you have to process over 110000 data entries but processing over 60 minutes is still kind of long. So I was wondering if anyone could propose a different method of doing this..... Love to heard any replies... Allen __________________________________________________ Do You Yahoo!? Tired of spam?

all_meta_types confusion
by Garth B. 09 Jan '07

09 Jan '07

Hey everyone, Zope 2.9.6 I'm trying to filter the objects that appear in the Add drop down, and I'm having odd results. There are two scenarios. In the first scenario, the active user is a Manager and my folderish object does not have a defined all_meta_types function. Everything shows up in the Add drop down as expected. When I define all_meta_types for my folderish object to only return one kind of object, the "Add xxxxx" button appears as one would expect. In the second scenario, I have a role "Editor" which controls what kinds of objects the user can add. When I do not have an all_meta_types function defined on my folderish object, only those objects that the role permits the user to add are shown. When I define all_meta_types for my folderish object to only return one of the kinds of objects that the role does permit, the user can't add anything. No "Add xxxxx" button that one would normally see when only able to add a single type of object to a folderish object. For the same type of object, and when logged in as an "Editor", the call to user.has_permission() (around line 254) in filtered_meta_types() in ObjectManager.py, returns false when all_meta_types is defined, and returns true when it isn't. I don't know why the user would not have permission to add this type of object when all_meta_types is defined versus when it isn't. This is why I'm confused. No errors or exceptions. So, in summary, when I don't have all_meta_types defined for my folderish object, the five types of objects the role is permitted to add is shown in the Add drop down. When I set all_meta_types to only permit one of those five types of objects to be added, the user can't add anything. A user with the Manager role doesn't appear to have this problem. Any suggestions for what's going on here? Any insights are appreciated! Thank you, Garth

There is other solution that uses RDBMS to what I'm trying to do, and I'm considering using PostGreSQL after. But before that, I want to using ZOPE and ZODB because I feel this could work. But in ZOPE vs RDBMS, why do you consider RDBMS first, why not ZOPE? can your give me the pros and cons in your perspective? ----- Original Message ---- From: Jonathan <dev101(a)magma.ca> To: zope(a)zope.org Sent: Tuesday, January 9, 2007 9:21:18 PM Subject: Re: [Zope] need advice on mass data processing ----- Original Message ----- From: "Andrew Milton" <akm(a)theinternet.com.au> To: "Andreas Jung" <lists(a)zopyx.com> Cc: "Zope" <zope(a)zope.org> Sent: Tuesday, January 09, 2007 4:21 AM Subject: Re: [Zope] need advice on mass data processing > +-------[ Andreas Jung ]---------------------- > | > | Sorry, but you are misusing Zope.

One caveat though... if you want to be able to do a text search on the string portion of your data, then ZCatalog would be an appropriate tool.

Solved (Re: Strange ZEO related Tracebacks (ZEO.cache, line 915, in _makeroom))
by Jean Jordaan 08 Jan '07

08 Jan '07

Hi all > * Module ZEO.cache, line 915, in _makeroom > > KeyError: 10201651 It turns out that this was due to an undersized /tmp partition (17M, while the default cache size is 20M). Configuring Zope to use a persistent cache made this error go away. -- jean . .. .... //\\\oo///\\

My problem, however, is that the passwords are encrypted by default in exUserFolder, and I do not now how to migrate those encrypted passwords back to the normal User Folder. Any ideas? Thanks, Chris
