Wheeeeeahh ! You are the best. The name "Brian Lloyd" doesn't sound like a girl name, so I won't kiss you :-) And I don't even remember of the internet site that allow one to send so-called "virtual beer" to a fellow. By the way, IE 3.x fails to expire Cookies. I think I found the trick. the max_age parameter seems to confuse IE 3.x. Included are patches for lib/python/ZPublisher/Response.py and lib/python/ZPublisher/HTTPResponse.py Any comment are welcome. If there are no problems, I will submit this to the Collector.

Stay tuned for more informations. This is a known problem, already in the python TODO file. I don't know if the new version (python 1.5.2b2) solves the problem. However, the python TODO list reads: 3.4. sequential arg after kw arg generates bad code w. warnings For example: >>> def desc(*args, **kw): pass >>> desc(1,2,'foo',x=None,desc) <stdin>:1: underflow! nexti=27, level=6, n=7 <stdin>:1: underflow! nexti=28, level=0, n=1 SyntaxError: non-keyword arg after keyword arg >>> This explains why  shoots pci_handle which don't expect the "<stdin>:1:underflow..." lines.

Is there any reason why I can't do what I require? Have you tried viewing the source of the error page?

The big 3, and Zope initiatives for Linux Expo
by Brian Lloyd 13 Apr '99

13 Apr '99

Hi all, This fits right in with Karl's post about the "big 3" components of an effective portal site... :) As many of you may know, we at DC are in the middle of a push to position Zope as powerful and flexible portal-building software. We are making progress on a number of fronts toward this goal, and we want to make sure that what we are doing has some visibility in the Zope community. We will be exhibiting at the upcoming Linux Expo the week of May 18 in Raleigh, NC - our goal for the Expo is to demonstrate the Zope message of "unleashing potential", which means: o Open Source o Community Portal o Through the Web o Safe Delegation of Control We plan to demonstrate this by reinventing the zope.org site, using it as a demonstration and case-study of a portal site that incorporates: o Powerful information browsing and searching o News items o Issue tracking o Community membership o Community projects o Personal areas that community members can maintain themselves o Community involvement in the form of polls and discussions We will be building this site as a real-world example that will, in fact, replace the current zope.org site by or shortly after the show. Though it will certainly continue to evolve over time, we plan to get as much of the functionality above as possible into the new site by the Expo. The end result will, we hope, be a site that allows much better organization, greater community involvement, and better visibility of projects and community resources.

sql INSERT during query
by Jay, Dylan 13 Apr '99

13 Apr '99

I am trying to add a new record to a table based on the query to another table. Everytime I try this I get a "400 Bad Request" error with no debug info. Is there any reason why I can't do what I require? I am using a URL like "Download/qryGetUnregUser/MagicNumber/14777794/completeReg" where qryGetUnregUser is select * from unregUsers WHERE MagicNumber =  and completeReg is  <h2></h2>  <p> Thank you  for taking the time to register. You have been succesfully registered. You may now enter restricted parts of this site by entering your username <i></i> and password.</p>  and qryAddRegUser is INSERT INTO users VALUES ( , , , , , , , 'Customer', '' ) I have tried making completeReg have proxy Manager permission. What am I doing wrong?

Re: [Zope] Anything like a for loop in DTML?
by Bill Randle 13 Apr '99

Phil, I asked this same question awhile back. The answer is to use an External Method. The Python equivalent is the "range" operator, but "range" is not included in Zope due to possible problems with runaway memory usage if a really big number was used. [In the example below you'll see that a max limit is set. If it were a standard feature, where would one set the upper limit?] Copy this code to a file (say "looprange.py") and put it in ZOPE_HOME/Extensions (you may need to create the directory). # simple extension class to implement a counting loop LoopRangeError = 'LoopRangeError' # Name an exception class. loop_range_limit = 100 # Maximum allowable loop index. def looprange(max): if max <= loop_range_limit: return range(max) else: raise LoopRangeError, max Select External Method from the Add list and add this method (id="looprange", method="looprange", file="looprange.py"). Now you can use it in your DTML like this:  ... do some stuff for each loop iteration ...  In my case "ltblSize" is a property of the DTML Document, but it could just as well be a local variable in your REQUEST object. -Bill Randle Central Oregon Internet billr(a)coinet.com

RE: [Zope] help with magic method "__of__"

I'm afraid i can only give you a sketchy answer. __of__ is a cue for acquisition - it wraps the instance in question with the context of what you want to be considered the instance's container. (The creation of a new, enwrapping instance is to avoid creating any reference loops that would defeat garbage collection.) This way attribute lookups in the new instance can fall through to the attributes of the container, even if the reference is not explicitly made through the container. I was hoping to find a document on the site that explains this better, but the closest i could come is one of the acquisition docs that explains something else in terms of __of__ - http://www.digicool.com/releases/ExtensionClass/Acquisition.html . Maybe someone else can point out a better document - or explain the concept (which i've only been exposed to, not yet really explored) better than i have... Ken Manheimer klm(a)digicool.com

This is exactly the configuration I have. I have the management screens running on IE and I run a new netscape each time to test it.

Zope startup problems
by Alex Rice 12 Apr '99

12 Apr '99

Hi, after a great experience with the Zope Linux/x86 binaries, I am now trying to get a source installation running for the first time, but seem to have overlooked something. This is on a Cobalt RaQ. This is a MIPS processor with Linux 2.0.34. Basically a RedHat box. I built Python 1.5.1 and Zope-1.10.2-src with no problems. I'm using Apache. When I go to this URL: http://zope.swcp.com/Zope/ I see Zope.cgi process, then I see in my browser after about 15 sec: ! Temporarily Unavailable The resource you requested is temporarily unavailable - please try again later. (102) failure during connect  In /usr/share/zope/var, I have only Data.bbb Data.bbb.in (pcgi.* seem to be missing?) Also, I do not see suspicious entries in apache's access and error logs. Below is the relevant section in my Apache config. But the rewrite rule seems to be working since the Zope.cgi process is getting started. Would really appreciate any suggestions. Thanks! <VirtualHost 198.59.115.167> ServerName zope.swcp.com ServerAdmin admin DocumentRoot /home/sites/home/web/zope ScriptAlias /zope-bin/ /home/sites/home/web/zope/cgi-bin/ <Directory /home/sites/home/web/zope/cgi-bin> AllowOverride None Options FollowSymLinks ExecCGI </Directory> # Zope configuration maps everything to the Zope.cgi CGI script RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/Zope/(.*) /home/sites/home/web/zope/cgi-bin/Zope.cgi/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] </VirtualHost> Please cc: alrice(a)swcp.com on your reply since I'm only in the list digest.
