I am running the server and the browser on RedHat 6.1. The original poster was as far as I can recall on Solaris. When I run the browser on Windows 95 (and the server on RedHat), then *that* bug does not occur, but another nasty bugs (server crashes, sometimes with error messages) do seem to happen. I mailed to Jim Fulton about this too yesterday (and I think I sent a cc to support). I don't consider it to be a minor bug, as I do a lot of restarts during product development. Zope 2.0 on the same machine restarts just fine. I can do some more testing next week if you want, but I did test quite a bit yesterday and it's definitely Not Working for me, for browsers remote or local, though the symptoms are different (each bad).

Any body know what this means, it appears after I use the web browser, and the server crashes. It seemed to work OK until I did a lot of DHTL editing File "/home/sites/site2/web/cgi-bin/Zope-2.1.1-src/z2.py", line 579, in ? pf.close() IOError: [Errno 1133] Quota exceeded

Getting started, product suggestions, advocacy
by srl 07 Jan '00

07 Jan '00

Hi all--- I'm working on getting a sample install of Zope going at my office, mostly for demo purposes. Ideally, I'd like to do a proof-of-concept for a community portal-type site, which needs the following features: -page personalization for users -RDF channel importing (for headlines) -threaded discussions -ideally, group-based scheduling/messageboards I have Zope installed on a Solaris box. the only database I have installed at the moment is MS SQL Server 7.0, which I could talk to through ODBC. -will Zope talk to SQL Server? if not, what free databases would you recommend? -What data should I be using ZODB for, and what data needs to be in a relational database? -What products should I look into for the tasks I need to do? -Ideas on a plan of attack that'll break me into using Zope relatively painlessly? Also, has anyone put together a Zope Advocacy page or FAQ that I can use with my coworkers? We're a ColdFusion web shop, and I need heavy ammo to convince people to learn another language. srl

newbie question - Adding properties during an import using fsimpo rt rt
by STEVENS,JEFF (HP-FtCollins,ex1) 07 Jan '00

07 Jan '00

I am importing a large number of files into Zope using fsimport. I would like to add a property 'foo' to each new DTMLDocument that is imported from the file system. I have tried to do this in the code immediately following the call to manage_addDTMLDocument (name, '', data), but I have been unsuccessful. The problem I am having is that I don't understand how to get the DTMLDocument object that was just added to the folder so I can call manage_addProperty on it. Below is a snippet of the fsimport.py code that I was trying to do this in. I have a feeling that the solution is pretty obvious, but so far it escapes me. Thanks for any help you could provide. Jeff def rcimport(fsdir, obdir): filenames=os.listdir(fsdir) for name in filenames: pathname=os.path.join(fsdir, name) if name[0] in ('.', '#', '_'): continue if name[-1] in ('~',): continue elif os.path.isfile(pathname): if _isdoc(pathname): file=open(pathname, 'r') data=file.read() file.close() obdir.manage_addDTMLDocument(name, '', data) elif _isimg(pathname): file=open(pathname, 'rb') data=file.read() file.close() obdir.manage_addImage(name, data) else: file=open(pathname, 'rb') data=file.read() file.close() fobj=File(name, '', data, content_type=_ftype(pathname)) obdir._setObject(name, fobj) elif os.path.isdir(pathname): obdir.manage_addFolder(name) rcimport(pathname, getattr(obdir, name)) else: __traceback_info__=(fsdir, obdir, name) raise ValueError, name

SyBaseDA and select count problem
by Bill Anderson 07 Jan '00

07 Jan '00

It seems that whenever I try to use any of the following: select count(*) from <tablename> select count(<columnname>) from <tablename> it returns: "Error, exceptions.ValueError: Empty column name, " Of course, the sql is tested and known to work. Any clues here? -- Bill Anderson Linux/Unix Administrator, Security Analyst ESBU (ARC) bill_anderson(a)boi.hp.com My opinions are just that; _my_ opinions.

converting SQL select list into unique values
by Darcy Clark 07 Jan '00

07 Jan '00

I have a non-unique column in a MySQL table - I have looked hard for a way in SQL to convert the results of a SELECT into a list of unique values. I know how to define a table at CREATE to have UNIQUE columns but this is not what I want to do. For example : If the result of the SELECT is : 1, 3, 3, 4, 2, 6, 8, 9, 4, 2, 3, 6 I would like to return: 1, 2, 3, 4, 6, 8, 9 i.e. only the unique values of the list. any pointers ? if SQL can't do this, can Zope ? (I'm sure Zope can do it, it can do everything :) Darcy -- --------------------------------------------------- Ph: (734) 764 3377 Email: darcyc(a)engin.umich.edu URL: http://www-personal.engin.umich.edu/~darcyc/ --------------------------------------------------- 'If you're not part of the solution, you're part of the precipitate' .....

RE: pgci problem with Zope-1.10.2 and pdflib
by Jeff Bauer 07 Jan '00

Nuno, I suspect you've got a problem with pdflib running as a cgi app under Apache, which is spewing some error message to stdout and confusing pcgi.

RE: [Zope] Testing products outside of zope (i.e., in python inte rpreter)?

If your code is not Zope depenent, you can. If your code it, you can use the Zope debugger (based on the Python debugger) but at that point you are not 'outside of Zope', you are just not accessing it through the web, but via a debugger prompt. > I find that I'm > restarting zope just to update my product and test it, and that seems > painfully slow.
