Zope just spun out
by Jason Spisak 25 Apr '00

25 Apr '00

I'm using 2.1.6 on RH 6.1 Right now Zope isn't responding after I did an undo in the management interface. The process is taking up 90% of the cpu power. I don't want to kill it, I want to get some useful info out of this. One more time...what can I do to get some info on this? hanging, -- Jason Spisak 444(a)hiretechs.com

ExtensionClass: calling basicnew from C code
by Andrew M. Kuchling 25 Apr '00

25 Apr '00

I'm still working with ExtensionClass to build a Versant module that supports persistence nicely, and just discovered the __basicnew__ method that returns an uninitialized instance of a class. Is there a good way to get the same effect as this method from the C level? Other than the following code: basicnew = PyObject_GetAttrString( classObj, "__basicnew__" ); if (basicnew == NULL) { Py_DECREF( classObj ); return NULL; } Erg = (VLinkObject*)PyEval_CallObjectWithKeywords(basicnew,NULL,NULL); This code seems to work fine; having to do a getattr seems inelegant, that's all. -- A.M.

How do I do that? =] Example: Product LotsOfImages has 50 images within it's main ZClass, main; How do you get the URL of the images from within a DTML Document, in main? -Morten

access control problem.
by David Brown 24 Apr '00

24 Apr '00

I've been learning about Zope as I go along hacking on my ZopeFIsh project. For the most part things have gone well, most problems having solutions. But I seem to have wandered into a weird little problem. Here's how it goes... I instantiate my ZopeFish object. I go it in the management interface, and add a user. In another browser window (one that I never used to log into Zope), I go to the ZopeFish instance and log in using ZopeFish's user login facility. I go to the discussion group page, click the "new message (in browser)" link, write something, hit the update button. At this point ZoepFish will create a new message, set the subject and contents, and then redirect the browser to the message that has just been created. At this point Zope wants a username and password. If I cancel the prompt, it will now tell me that I am unauthorized to access the attribute "body". "Body" is the actual message. You see, I'm using a tenplate structure -- only the root object has an "index_html" member, and it points to a template that includes a "<dtml-var body>" directive. So I just implement the "body" member in any publishable objects, and they all use the template. So somehow, creating the new message didn't properly propagate the security settings, or something else that I don't understand. So how do I properly set up the access to the new item? I noticed that if I just stop and restart the Zope server that I no longer have problems seeing the message. So something's getting fixed on the reload. I've uploaded my current source to: ftp://members.home.net/davidbro/ZopeFish-0.4.0-bug.tgz if anyone wants to dig around and try to reproduce (and maybe even fix) the problem. I'm trying to RTFM, but finding the right FM is tough. ZopeFish requires the latest XMLDocument. Thanks in advance... dave

Testing a ZCatalog index type
by Alexandre Ratti 23 Apr '00

23 Apr '00

Hello, Is there a way to test the type of a ZCatalog index from DTML or Python (eg. TextIndex | FieldIndex | KeywordIndex)? I can loop on "indexes" to get the index names. However, I had a look at the sources and I couldn't find any way to retrieve an index type. It looks like the index type is only used in "addIndex" in Catalog.py when first creating the index. Any hope? Thanks. Alexandre

Just so that it's noted
by Morten W. Petersen 23 Apr '00

The  syntax is deprecated, right? If it is removed in the future, it could be a "good thing" to have a product which accepts this syntax, because some people will be using HTML editors that only accept the old syntax. Should this be submitted as as "feature wanted" on the Collector? -Morten

Disable manage interface on-purpose
by Sin Hang Kin 23 Apr '00

23 Apr '00

The manage interface is really making web masters and boss worry. It seems not easy to separate them from an ordinary zope site without restricting its usage. However, with a production web server like these is really a danger. It is also a preventing device for un-technical user to adopting zope. Are there solutions such that to restrict the interactive management interface from being use with run-time option? May not a technically correct move, but certianly have reason for marketing. An anonymous-only flag? no-superuser flag? Rgs, Kent Sin ----------------------------------- Q u o t i n g F r o m Z o p e A d m L i s t ---------------------------- okay, that means that instead of it taking N tries to hack a password, it takes N^2 tries. *shrug* a little better. is there a way to run all the /manage pages behind SSL, so they're less prone to password sniffing? or to rename /manage to something a little more obscure? it just seems to me that the /manage URLs are just waiting to be exploited by some cracker. srl, picking security nits

Re: Some thoughts on spliter
by Sin Hang Kin 23 Apr '00

Searching through over a big collection with pattern matching is not good enough. So, your scheme would only works in small scale. With a small site or within one site, it would do well. When the amount of information is big, the simple and/or search is not enough. Then, we need to learn the word boundary for ideographical text. This would be done automatically or by human or combine with both, and is should not be limited by the system designer, because the technology will change and the best suitable way to findout the word boundary is always different. I strongly aginst the single character boundary solution, which have been in used for a long time in the currently implementation. When people think search is simple and they found the system useful in a small system. When apply this tech in internet, this is a joke. Do not go this way: You make a short life system which is not going to be useful in a short time. If you want to have such a system, simply modify the spliter.py and you have what you need, we do not need this build into the next generation zcatalog. Please don't.
