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:             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"

Re: [Zope-dev] Rendering DTML Document / Folder properties as structured-text
by Tres Seaver 14 Mar '99

14 Mar '99

Sorry to follow up my own post, but I think I understand the issue now. Since I saw at least one other person puzzled by this problem, I thought I'd try to explain (and let people shoot me down, if I am "even-less-than-an-egg"). > I am trying to capture "free form" input as a property of a Folder / DTML > Document, and display it using StructuredText. > > For instance, I define a property, notes, with type text.

The __doc__ comment in StructuredText.py specifies: - A paragraph that begins with a '-', '*', or 'o' is treated as an unordered list (bullet) element. This requirment prohibits "mashing" the lines together, as I naîvely tried to do above. I must leave a blank line between list entries, or else ST cannot distinguish them. This has the unfortunate side effect that all lists emitted by ST look "double spaced", because list items are rendered "around" paragraphs, e.g: <UL> <LI> Foo <LI> Bar </UL> I will look at what it would take to strip the "enclosed" from list items, and submit a patch if it looks simple enough (actually, a patch to allow parsing of list elements without the extra newline would be even better, methinks). -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

Product manage_traceback caching old old data?
by Anthony Baxter 14 Mar '99

14 Mar '99

I've got a product I'm developing, but I'm finding that interactive debugging of it is being foiled by Zope's Product interface's manage_traceback method. It's caching the very first error that occured - and after I shutdown zope and restart it (having fixed the error) it still gives the same traceback. It's possible that the problem is simply the "Products" listing is at fault - it's still showing the product as "broken", even though else where in Zope I can now add products fine. Any ideas? This is with Zope 1.10.2, under ZServer.

Rendering DTML Document / Folder properties as structured-text
by Tres Seaver 14 Mar '99

14 Mar '99

I am trying to capture "free form" input as a property of a Folder / DTML Document, and display it using StructuredText. For instance, I define a property, notes, with type text. I then attempt to display it, using this DTML:  I then enter values into the TEXTAREA for the property, e.g.:: * foo * bar When I display the document, I get mixed results: sometimes it will be partly rendered as HTML, while sometimes I get the infamous "read only buffer, class" error. What am I doing wrong? -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

RE: [Zope-dev] Re: [Zope] sequence of numbers
by Shaw, Howard 13 Mar '99

13 Mar '99

Perhaps if you added a python function which performed range checking and constrained the command to generating between 1 and 100 numbers, etc, DC might be willing to integrate the patch, since this would not leave open the hole DC feared (i.e. ask Python to generate several billion length range). If the range was insufficient for anyone, they could easily modify that code snippet... Thus the Zopist could tune the function to be useful. I am sure DC didn't spend a lot of time on _. functions. They have much else to do, but I expect if you create a wrapper that can make a pythonic function safely available and provide a patch they will probably consider integrating it. Howard C.
