Hi all, i recently tried the ttw product from COM.lounge. It's really nice, but when i add a filetype-field in the Formulator page and i try it in Plone i get the error message "unpickleable Object". Is this a bug or have i missed an option? Thanks! Stefan Kanitz Wiesbaden University Of Applied Sciences Dept. Of Media Management

Zope Installation Problems
by Sheppard Norfleet 04 Mar '03

04 Mar '03

I am using Rad Hat Linux 7.x. which comes with python 2.2 not the problem. I have Zope that has a python 2.1 one with it. when I try to build w_pcgi.py using the python that comes with zope, I get compile errors when trying to build the exception modules, the last message has a message like "I and PICKY raiseError" There are a ton of warning and a few errors sprinkled in a compiler output (or at least it looks like that). Anyway I have been working at this installation for about a week, I have tried a source install and binary install. No matter which way I go zope fails to build using the 2.1 python that comes with it. Has anyone else had these problems? Trying to run Zope like this: bin/python z2.py -p /usr/local/apache/cgi-bin/zope.pcgi all I get in return is a new bash prompt wiht no warnings. the log files are empty or don't exist. Please help! BTW, don't mean to knock mailing lists but wouldnt forums be a lot easier way to communicate? Just a thought...

do I need to build a product for this?
by sameer chaudhry 04 Mar '03

04 Mar '03

I have done this using products but I'm wonder if the following is easier done within the Zope machinery. I want to have a python list at a URL say: some_server/list I want to update that list by appending a line of text to it by going to the URL: someserver/list/updatelist I want to see the updated list by going to the URL: someserver/list/viewlist. Is this possible without building a Product which supports the persistence of the list? -- _______________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup Meet Singles http://corp.mail.com/lavalife

Python calling python?
by Michael Havard 03 Mar '03

03 Mar '03

Somebody make this simple for me. I have two python scripts (internal not external). I want to call the first script using DTML/ZPT. I have no problem in that regard... BUT... I want to call then use th first script to call the second script. As soon as I try to include that functionality it falls apart. If I try to import I get 'not authorized'. If I try to access it the same way I do ZSQL methods 'context.whatevername()' I get "whatevername" not defined. What am I missing? Is it a security thing? Did I miss some important piece of documentation? _________________________________________________________________ Add photos to your e-mail with MSN 8.

dtml files in dtml files? getting frames to work on a simple Product
by sameer chaudhry 03 Mar '03

03 Mar '03

I am trying to write a simple web based chat server Product. The interface is simple with a frame for entering text, and another frame for viewing the chat so far. My problem is that in a dtml file, I put links to two other dtml files (those being the two frames), and the frames don't show up. How can I make this work? -- _______________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup Meet Singles http://corp.mail.com/lavalife

Not sure if this is slower or not. I also have the impression that ODBC is slower per se, but perhaps coupled with better connection pooling it makes mxODBC faster? Nad how would mxODBC's pooling differ from Zope's "pooling" of connections by keping them open? I understand from previous mailexchange that the preformance of a heavly DB driven (DB=RDBMS) is in part defined by the amount of ZODB-connections as well as the amount of threads available to the Zope-process. I wonder though if the *sheer number* of active/connected ZOracleDA objects in the ZODB has some relevance to those numbers (ie. more open DA objects means increase threads and/or ZODB connections?). I have not read any specific numbers and I have yet to begin to understand how the amount of ZODB connections has an impact on the usage of ZOracleDA connections/objects. We do have experienced problems when using many connections to different schemas and I know that at least one more person has experienced similar problems (mem leaks, etc). Some of them wnet away as we reduced the amount of DA objects. Also, I would like to know how the kind of connection pooling that mxODBC uses benefits Zope. Does it spawn it's own threads in an external process or how does it work? Would it be possible to increase the performance of DCOracle2 by using similar tchniques? Thanks, /dario
