I'm not actively being plagued by this right now, but I'm sure I'll forget all this and run into the problem again, so I'll save this message. Thanks, // mark -

Whither David Shaw?
by Paul Winkler 24 Sep '02

24 Sep '02

I'm looking for David Shaw - got an issue with his docs at http://www.zope.org/Members/dshaw but the email address given on all the product pages bounces with "mailbox disabled". David, are you out there? -- Paul Winkler "Welcome to Muppet Labs, where the future is made - today!"

url growth
by Dennis Allison 24 Sep '02

24 Sep '02

Zope internally constructs URLs which can get very long and very redundant. I have one example in the logs now -- /A/B/C/C/C/C/C/C/C/D/ where the C's are completely redundant. How does this happen and what, if anything, can be done to minimize the problem? (I know this has been discussed on the list before, but a quick google didn't turn up anything...)

IO Error Broken Pipe with Photo Product
by complaw＠hal-pc.org 24 Sep '02

24 Sep '02

I'm using the Photo product on the FreeZope site (http://www.freezope.org/) I've loaded many photos onto the web site, but yesterday and today I am unable to upload photos. Instead, I receive the following error message: Site Error An error was encountered while publishing this resource. IOError Sorry, a site error occurred.

The files themselves are fine, being read with a variety of software applications, including Konqueror and Mozilla. Any idea what the problem might be so that I can pass that along to the FreeZope people? Thanks in advance, Ron

DocumentLibrary: can we read HTTPS?
by Ken 24 Sep '02

24 Sep '02

I copied over my Products, Extensions and various modifs from my previous install in order to run Zope using a HTTPS-enabled Python. KebasData is again able to read in HTTPS pages, but trying to make this work with DocumentLibrary failed. I must admit I didn't know what to expect, but I thought both products use the same Python module (useragent from my logs is Python-urllib/1.15), so it would work. The error: Traceback (innermost last): File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 114, in publish File /usr/local/www/Zope/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: doctest) File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 98, in publish File /usr/local/www/Zope/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: document_submit) File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: document_submit) File /usr/local/www/Zope/lib/python/OFS/DTMLMethod.py, line 127, in __call__ (Object: document_submit) File /usr/local/www/Zope/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: document_submit) File /usr/local/www/Zope/lib/python/DocumentTemplate/DT_Try.py, line 140, in render File /usr/local/www/Zope/lib/python/DocumentTemplate/DT_Try.py, line 174, in render_try_except File /usr/local/www/Zope/lib/python/DocumentTemplate/DT_Raise.py, line 56, in render (Object: URLError) URLError: (see above) -- I hope someone can provide me with some insight on this, it's important! ----------------------------- Chris, re: my earlier post >> ...following this, the script exits: >> >> !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! >> There were errors dUring Python module compilation. >> !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! >> *** Error code 1 >> Stop in /usr/ports/www/zope. >Do you have an INSTANCE_HOME setup and have extension Products like CMF installed? >I've seen this erro when the python script part of the >Zope builder tries to >build things like filesystem Script (Python)'s by mistake. >Using INSTANCE_HOME solves this problem... >cheers, >Chris Chris: I think your mail may have crossed paths with mine. Turns out there was no problem installing Zope from the FreeBsd port. It was me... I never really got what INSTANCE_HOME was all about, I should read up on it. I do have it in 3 places in my start file. But if you are referring to some setup that exists prior to installing Zope, I don't know about that.

FW: BASE and IMG and [X]HTML
by Charlie Reiman 24 Sep '02

24 Sep '02

I asked the www-validtor mailing list what's up with the img vs. base tag thing in XHTML. Here is the explanation. His comments make sense and I really have nothing to add other than it looks like I need to switch hardcore to XHTML if I want anything to validate. If you want to pester Kynn then it would be good form to join the www-validator mailing list. Charlie. -----Original Message----- From: www-validator-request(a)w3.org [mailto:www-validator-request@w3.org]On Behalf Of kynn(a)idyllmtn.com Sent: Monday, September 23, 2002 2:01 PM To: Charlie Reiman Cc: www-validator(a)w3.org Subject: Re: BASE and IMG and [X]HTML Charlie Reiman asked: > We've been having a discussion on the zope mailing list regarding the > validator's behavior with <base ... />. In particular, an HTML 4.01 > transitional document is not allowed to use <base ... />. Instead, it is > expected to use <base ...>. > > Well, okay. I don't like it but I accept the reasoning. But why does it not > complain about <img ... />? Isn't this the same situation? Hi, Charlie, it goes like this. You and I both know that HTML 4.01 is html written according to SGML rules, and XHTML 1.0 is html written to XML rules. In the SGML-HtML rules, the closing > on a tag is actually optional in many cases, and when it's not there, the assumption is that it's meant to be there, and anything else is just character data. Why is that important? Well, it makes sense when you combine it with someone else -- a slash / can't appear inside the tag in SGML-HTML. So when an SGML-HTML application (such as the validator) sees the following: <img src="blah.jpg" alt="Blah!" /> It reads it as: < Okay, the start of a tag. img Aha, this is the image element src="blah.jpg" Okay, this is an attribute alt="Blah!" This is another attribute / Wait, what the heck is this? This can't appear inside this tag. Oh, I get it. The tag actually closed after the last valid attribute, they just didn't include the >. Okay, so the / is some character text data after the tag. > Hmm, I guess this is still character text data. So really it reads it as: <img src="blah.jpg" alt="Blah!">/> Now, the browsers out there aren't really SGML applications. So they don't follow the SGML rules properly, and won't read it that way. Instead they'll read it as: <img src="blah.jpg" alt="Blah!" [SOMETHING I DON'T KNOW SO I WILL IGNORE]> ...which means it will display as you'd expect. Okay, so what's the problem with <base /> not being allowed but <img /> is? Simple: The HTML specs don't allow "raw" character data text to appear inside the <head>, but they do allow it to appear inside the <body>. When you write <img />, that extra /> -- as the validator reads it -- follows the <img> and is within the <body> text, where character text is perfectly valid. When you write <base />, the /> appears in the <head> element, and that's NOT allowed, so the browser throws an error atcha. --Kynn

Upgrading Zope instances from 2.5 to 2.6a

Hello, I am trying to upgrade one of our instances from Zope 2.5 to 2.6a ... We are running the instance using INSTANCE_HOME so I have just started to Zope-2.6 with this instance home ..
