PUT_factory and changing ids
by Florent Guillaume 14 Mar '03

14 Mar '03

Is a PUT_factory allowed to return an object with a different id than the requested one? Currently NullResource.PUT doesn't cope with that. But in CMF an object factory is allowed to change the id from the requested one, so I'm wondering what could happen, and what's best.

Conflict reduced BTrees for cataloging
by Dieter Maurer 14 Mar '03

14 Mar '03

I am working on a CMS on top of ZODB for large amounts of large SGML/XML documents. To speed things up, a colleague started two import processes and we get incredible amounts of "database read conflict error"s from cataloguing (although we already use "QueueCatalog" for most indexes). I think, the data structures used for cataloguing and indexing could have a "def _p_independent(self): return 1". Does anybody objects? If not, I will implement "_p_independent" BTrees and friends.

Pydoc and Zope
by Joachim Werner 13 Mar '03

13 Mar '03

Hi! I've used Pydoc with Dieter Maurer's patches to browse the Zope sourcecode before. These patches are quite old and probably incompatible with current Zope versions. Is there a HOWTO for using Pydoc with a current Zope? Are there any new adapted versions of Pydoc? Or is there any better way of browsing the source code?

install complains about 'invalid' Python files
by THerp＠apriori.de 13 Mar '03

13 Mar '03

Hi, I hope this is the proper list for my question, or at least for my suggestion. I have a Python product which contains Python scripts (*.py) and DTML methods (*.dtml) which can get used by the user to create certain standard versions of e.g. generated menus etc.; the ZODB objects can then be customized. The templates are located in a certain subdirectory of my product. This works fine. When I run the Zope install script on a freshly installed Zope, and my Product is already there, it complains that the *.py scripts (aimed for import) would be invalid, because there are return-, but no def statements. Thus, installation fails; I must first remove my product. My question: is it possible to tell the install script not to compile a certain directory subtree, e.g. placing a certain file somewhere? My suggestion: if there is no possiblity yet, it would be great if it would come in a future version. tia, Tobias http://www.apriori.de --

Well, I wanted to avoid this. But since this seams to be the only possibility, I'll use .zpy instead (Zope PYthon script) and tell vim to highlight them as Python. Thanks, Tobias

I don't know what work means in this context, but think the ZConfig project is thorough. In my checkout there are 180k of document, 180k of unit tests, and 136k of code. A measure of work that suggests that something with 0k of documentation and tests and 136k of code would be better makes no sense to me. > The point I'm trying to make is that Zope has learned nothing from the > UNIX philosophy. Yes, you can extend the config schema. You can grow I don't see where the UNIX philosophy has anything useful to say about configuration, but maybe I'm just a closet unix hater <0.5 wink>. > new, better config files, of extraordinary magnitude.

I don't see that configuration gets any easier if you have multiple processes. Even if Zope had N processes, there would still be the same amount of stuff to configure. You'd probably still want a single master config file for the whole thing, and a tool to check the configuration is valid separate from the process that uses the file to configure itself. As I watched everyone working on the ZConfig project, I was impressed with how many issues are involved in getting a decent configuration system. I don't think that break the server into multiple pieces would make it easier to configure, and I don't see what requirements could have been eliminated to make the project take less work. Jeremy

Documentation
by Manoel Filho 12 Mar '03

12 Mar '03

Hi! My name is Manoel from Rio de Janeiro, Brazil. I'm very early in Zope. I was wanting make my jobs with a good presentation. So I downloaded "Zope Website Documentation Tool". I followed the instructions. Unpacked the file, copy it to the "import" folder, gonne to root folder in Zope and then clicked "import" button. Unceremoniousness Zope said to me : The object "broken" does not support this operation! Why? What this is mean? Did I make something wrong? Maybe I broke the object? Anybody can help me? I'm running Zope 2.6 in a Pentium 233 stand alone, under Windows 98SE and ZServer. Manoel Filho (55)(21) 3419-4459 Cel. (55)(21) 9879-4684 manoel(a)braxcom.com

Zope Template Newbie question
by David Cain 11 Mar '03

11 Mar '03

I'm trying to pull in another file with the following markup: <span tal:replace="here/level2banner">Level2banner content goes here</span> And it does pull the file in, but it quotes the entire HTML in that file so that my browser doesn't interpret it: <img src="/images/page2leftbottom-blank.jpg" width="331" height="39" border="0" class="banner" alt="Category"> This is not what I want. What am I doing wrong, or how to I prevent the quoting?
