Bug in FindSupport.py?
by Stefan Franke 18 Mar '99

18 Mar '99

In OFS.Findsupport, line 159, I found if hasattr(ob, 'aq_base'): bs=ob.aq_base if ( (not obj_ids or absattr(bs.id) in obj_ids) [...] That is a conditional assignment to bs, an bs is used later on in any case. Shouldn't there be an else-fork, like if hasattr(ob, 'aq_base'): bs=ob.aq_base else: bs=ob if the object is accessed without an aquisition wrapper? This lead to an error with one of my products, but propably my product is still faulty, and this only reveals the above problems. Stefan

Python 1.5.2b2 and Zope ODBC problems
by Brad Clements 17 Mar '99

17 Mar '99

I'm trying to run Zope on WIN32 with python15.dll from 1.5.2beta2 (but I did re-add PySequence_In). As I recall from previous messages, the python15.dll shipped with Zope is "special", and has some modules compiled with it that aren't normally in python15.dll Is this true? Can someone clarify this? Anyway, I can get it to mostly work, but my ODBC DA isn't working. I'm not sure if this is an incompatibility with sql.pyd, or a missing function in python15.dll. I get an exception as follows: Sorry, an error occurred.<p> <!-- Traceback (innermost last): File E:/Program Files/ZopeOne/lib/python\ZPublisher\Publish.py, line 878, in publish_module File E:/Program Files/ZopeOne/lib/python\ZPublisher\Publish.py, line 590, in publish (Info: ) File E:/Program Files/ZopeOne/lib/python\OFS\DTMLMethod.py, line 157, in __call__ (Object: index_html) File E:/Program Files/ZopeOne/lib/python\OFS\DTMLMethod.py, line 153, in __call__ (Object: index_html) File E:/Program Files/ZopeOne/lib/python\DocumentTemplate\DT_String.py, line 513, in __call__ (Object: index_html) File E:/Program Files/ZopeOne/lib/python\OFS\DTMLMethod.py, line 149, in __call__ (Object: standard_html_header) File E:/Program Files/ZopeOne/lib/python\DocumentTemplate\DT_String.py, line 513, in __call__ (Object: standard_html_header) File E:/Program Files/ZopeOne/lib/python\OFS\DTMLMethod.py, line 149, in __call__ (Object: NewsSidebar) File E:/Program Files/ZopeOne/lib/python\DocumentTemplate\DT_String.py, line 513, in __call__ (Object: NewsSidebar) File E:/Program Files/ZopeOne/lib/python\Shared\DC\ZRDB\DA.py, line 374, in __call__ (Object: CopySource) Database Error: Sorry, an error occured Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com ICQ: 14856937

Python 1.5.2b2 missing PySequence_In
by Brad Clements 17 Mar '99

17 Mar '99

Hi folks, I'm working on embedding zope in a custom win32 app, based on the latest python DLL. Looks like beta 2 is missing PySequence_In and PyEval_CallObject (deprecated), but this is causing problems with some existing .pyd Unfortunately I don't know which .pyd is the problem. Any suggestions on how to find it and correct it? Not sure if Guido is going to put those functions back..

bug in IE 3.x
by Service Informatique CHSR 16 Mar '99

16 Mar '99

Hello, I found another bug in IE 3.x: it doesn't expire cookie!!! This is very annoying, because: - I use UserDb for its ability to 'logout' someone - I can't consider for the moment using something else than IE 3.x for my users. About the last point: - IE 4.x consume far too much resources, and i don't want to install it for my users, who have old machines. - Netscape Navigator 3.x and 4.x have problem with style sheet (they ignore the font specification in the style sheet) and nested tables (the columns of a table that is inside another table aren't properly aligned). So the "best" choice is IE 3.x, but apparently, the method used to expire the cookie is not supported by IE 3.x (that is, setting a cookie that has an expiration date already passed) What about the new cookie specification? I remember i saw a ExpireCookie header (but perhaps i'm fool???) What can I do to solve that problem? Thanks, Jephte CLAIN Service Informatique CHSR

pcgi problems
by Quinn Dunkan 16 Mar '99

16 Mar '99

A while back I mentioned some intermittant problems with pcgi under irix, and someone else mentioned the same sort of thing. (the error is 'pcgi-wrapper: Error 0 (116) unable to connect, fd=3') I was wondering if the DC guys knew about this, or were interested in it, or have verified its existence or cause? On the subject of pcgi, the pcgi-wrapper syntax seems rather clunky (written, no doubt, with a single zope process, rather than a bunch of 'normal' cgi processes, in mind). It requires absolute paths for everything, and whenever you move one or create a new one it's sort of a pain. Suppose I have: #!/usr/local/apache/published/pcgi-wrapper PCGI_NAME=spam PCGI_MODULE_PATH=/usr/local/apache/published/spam.py PCGI_PID_FILE=/usr/local/apache/pcgi-data/spam.pid PCGI_ERROR_LOG=/usr/local/apache/pcgi-data/spam.log PCGI_SOCKET_FILE=/usr/local/apache/pcgi-data/spam.socket PCGI_DISPLAY_ERRORS=y PCGI_PUBLISHER=/usr/local/apache/published/pcgi_publisher.py PCGI_EXE=/usr/local/bin/python It would be nice to be able to shorten this to: #!/usr/local/apache/published/pcgi-wrapper PCGI_MODULE_PATH=../published/spam.py PCGI_DATA_DIR=../published/pcgi-data and have pcgi-wrapper intuit the rest of the values for me (provided that I stick pcgi_publisher.py in pcgi-data). What are the problems with this scheme? The second problem is the pcgi-data directory. Since pcgi processes are run as the httpd user (or none or whataver), that user needs write access to pcgi-data. The only solutions I see are either to make pcgi-data 775 and put it in the httpd group, or make it 777, which is the only option for normal users. I'm not too keen on the idea of 777 directories, but I don't see any way around it besides apache's suEXEC (which is plastered with Big Fat Warnings). Anyone else thought about this problem? One good solution I can think of is mod_pcgi. Is someone actually working on that (or planning on working on that), or are people just assuming surely someone will write it eventually? thanks!

ANN: Digital Creations Zope/WebDAV server available for testing
by Brian Lloyd 15 Mar '99

15 Mar '99

Hi all. We are happy to announce availability of a new server for interoperability testing, running a WebDAV-enabled version of Zope, Digital Creations' Open Source web application platform. Based on RFC2518, the new WebDAV support is tightly integrated with the Zope object model and security system. It is server independent, requiring no specific WebDAV support on the part of the web server in use. More information is available on the test server homepage at http://webdav.zope.org/. There are two ways to get access to the test server. A "Public" area which supports read-only DAV operations is available from the test server homepage at http://webdav.zope.org/. To be given access to your own private area where you can test write operations (PROPPATCH, MOVE, DELETE, etc.), please send an email to webdav(a)zope.org. The recipient is a human, so the command language is pretty flexible :) We'll send you a confirmation and instructions for accessing your private area of the test server. We would like to hear the results of any interoperability testing you do - please send any feedback to webdav(a)zope.org. For more information on the Zope web application platform, please visit the Zope website at http://www.zope.org.

Confused about manipulating nested lists in DTML
by skip＠mojam.com 15 Mar '99

15 Mar '99

I have a list of lists: [['Washington', 'state'], ['Washington', 'state', 'Auburn'], ...] The first element has length two, the rest length three. If I pass that to a DocumentTemplate instance as a parameter named "data" and manipulate it thus:       <p>  <br>    I get the following output: 9 [['Washington', 'state'], ['Washington', 'state', 'Auburn'], ['Washington', 'state', 'Bainbridge Island'], ['Washington', 'state', 'Bellevue'], ['Washington', 'state', 'Bellingham'], ['Washington', 'state', 'Bremerton'], ['Washington', 'state', 'Chehalis'], ['Washington', 'state', 'Chimacum'], ['Washington', 'state', 'Cosmopolis'], ['Washington', 'state', 'Cowlitz County'], ['Washington', 'state', 'Ellensburg'], ['Washington', 'state', 'Elma'], ['Washington', 'state', 'Everett'], ['Washington', 'state', 'Friday Harbor'], ['Washington', 'state', 'George'], ['Washington', 'state', 'Gig Harbor'], ['Washington', 'state', 'Kennewick'], ['Washington', 'state', 'Kent'], ['Washington', 'state', 'Kirkland'], ['Washington', 'state', 'Lacey'], ['Washington', 'state', 'Lake Stevens'], ['Washington', 'state', 'Long Beach'], ['Washington', 'state', 'Longview'], ['Washington', 'state', 'Moses Lake'], ['Washington', 'state', 'Mount Vernon'], ['Washington', 'state', 'Oak Harbor'], ['Washin! gton', 'state', 'Ocean Shores'], ['Washington', 'state', 'Olympia'], ['Washington', 'state', 'Packwood'], ['Washington', 'state', 'Pasco'], ['Washington', 'state', 'Phila/fort'], ['Washington', 'state', 'Port Angeles'], ['Washington', 'state', 'Port Townsend'], ['Washington', 'state', 'Pullman'], ['Washington', 'state', 'Puyallup'], ['Washington', 'state', 'Redmond'], ['Washington', 'state', 'Renton'], ['Washington', 'state', 'Richland'], ['Washington', 'state', 'Seattle'], ['Washington', 'state', 'Snoqualmie'], ['Washington', 'state', 'Spokane'], ['Washington', 'state', 'Stevenson'], ['Washington', 'state', 'Sunnyside'], ['Washington', 'state', 'Tacoma'], ['Washington', 'state', 'Twisp'], ['Washington', 'state', 'Vancouver'], ['Washington', 'state', 'Walla Walla'], ['Washington', 'state', 'Waterville'], ['Washington', 'state', 'Wenatchee'], ['Washington', 'state', 'Winthrop'], ['Washington', 'state', 'Woodinville'], ['Washington', 'state', 'Yakima']] 18 ['Washington', 'state'] 18 ['Washington', 'state', 'Auburn'] 18 ['Washington', 'state', 'Bainbridge Island'] 18 ['Washington', 'state', 'Bellevue'] 18 ['Washington', 'state', 'Bellingham'] 18 ['Washington', 'state', 'Bremerton'] 18 ['Washington', 'state', 'Chehalis'] 18 ['Washington', 'state', 'Chimacum'] 18 ['Washington', 'state', 'Cosmopolis'] 18 ['Washington', 'state', 'Cowlitz County'] ... *What* objects have lengths of 9 and 18? The outer list is length 33. The inner lists are all length 2 or 3. Obviously I screwed up and misused len(), but how?

dev and cvs
by Dave G 15 Mar '99

15 Mar '99

I hope this is the right place to ask this :^) I got and compiled cvs, it works fine. I made a quick shell script for it, now I just type "getzope" and it goes after the latest version. No problem, tested it Friday night. As a newcomer to cvs I got a silly question, do I built zope in the same directory that the cvs uses? or do I need to copy it over to a temp directory for playing, deconstructing, etc. DAve. "On the Plains of Hesitation bleach the bones of countless millions who, at the Dawn of Victory, sat down to wait, and waiting -- died"
