getting traceback involving BIGFLOAT
by Matthew Wilbert 13 Nov '99

13 Nov '99

I was running Zope2 successfully under RH Linux 6.0. using pcgi behind Apache. I had a hardware problem and by the time I was able to fix it, I had to do some reinstalls, particularly of Python. Zope didn't like it. Now I have it almost working, but when I try to go the initial Zope page, I get a traceback that I can't figure out. It goes: /usr/lib/python1.5/site-packages/ZPublisher/Publish.py line 214 in publish_module /usr/lib/python1.5/site-packages/ZPublisher/Publish.py line 120 in publish /usr/lib/python1.5/site-packages/ZPublisher/Publish.py line 259 in get_module_info /usr/share/zope/lib/python/Zope/__init__.py line 94 in ? /usr/share/zope/lib/python/ZODB/__init__.py line 111 in ? /usr/share/zope/lib/python/ZODB/DB.py line 91 in ? /usr/share/zope/lib/python/ZODB/Connection.py line 96 in ? /usr/share/zope/lib/python/ZODB/ExportImport.py line 92 in ? /usr/share/zope/lib/python/Shared/DC/xml/ppml.py line 337 in ? /usr/share/zope/lib/python/Shared/DC/xml/ppml.py line 382 in ToXMLUnpickler ImportError: (<class exceptions.NameError at 80d59e8>, 'BINFLOAT') Any ideas as to what might be messed up would be appreciated.

You can take an existing Zope site and fire it up with Zeo in a few seconds, and then switch back to the original threaded mode just as quickly. -Michel

For the Intel platform or to get the source RPM, go to: http://starship.python.net/crew/jrush/Zope/ or you can find it via the 'rpmfind' tool that searches the RDF network. >Anyway I think that it can not works directly out of the Red-hat instalation >because of the fact that pyhton with red-hat 6.0 is version 1.5.10 whithout >thread. So you have to recompile or reinstall python. It works under Red Hat 6.1 and in fact, ships on the Power Tools CDROM that comes with that release. Red Hat 6.1 ships Python 1.5.2 w/threads. -Jeff Rush

Is there any way to get selected text + control-c to behave in the expected way on winnt/9x. I have a table which when copied into an excel spreadsheet from either NS 4.5 or IE5 is just crap. Anybody know how to make tables copy to the selection as tables? -- Robin Becker

Related question -- if _adding_ threads doesn't gain much raw performance, then is it a sound workaround, on a site that (a) does a lot of OODB writing and (b) doesn't take a ton'o'hits, to turn threading off to avoid the dreaded ZODB conflicts. It seems this wouldn't lose much performance either. Or will the nifty async properties of Medusa still allow >1 transactions to have ZODB conflicts? Basically, is threading the _only_ way Zope can ever overlap requests internally? I'm looking to document a workaround that *guarantees* those conflicts never happen, even at some small loss of performance. -Jeff Rush

Python in expressions
by Clarence Gardner 12 Nov '99

12 Nov '99

Hello, it's my first day with Zope! I'm trying to do a simple Python expression, e.g., <dtml-if "divmod(33,2) == 1"> a </dtml-if> I get a NameError. I was given to understand that double-quoted expressions are normal Python expressions, and divmod is a builtin, so there shouldn't be a problem. Just for the heck of it, after that error, I tried <dtml-if "_.has_key('divmod')"> which evaluated to false. Am I missing something simple here?

Zope database on a relational DB [Q]
by Bruno Mattarollo 12 Nov '99

12 Nov '99

Hello. Is it possible to store the Zope database (Data.fs) into a relational one? For example an Oracle 8i? Would that be possible in the future? I mean, since you can export an object into XML and this is been integrated quite well (my opinion only) into Oracle 8i, it can be done, no?

namespace question
by rmilner＠point-one.net 12 Nov '99

Hello. I have a standard_html_header defined in the root folder that looks like this: <dtml-var header.html> So the actual header is keps in header.html which is also in the root. header.html has <dtml-var sidebar> in it. I defined sidebar in the root and override it in sub-folders but it sitll picks up the sidebar defined in the root. This didn't start happened until I did the above trick with standard_html_header and header.html. Any suggestions? I need the header file to have a .html extension so someone can edit them with dreamweaver. Is there an easier way to globally change the name of standard_html_header? Thanks, ^Roman
