These are products developed in Python, not through the web. Your products components consist of Python code and other artifacts (such as files containg DTML code). > What am I missing (and how do I get rid of this "mangling")? There really isn't any mangling going on, it's no possible for Zope to generate Python code or assume file names or anything else like that. When you develop a product through the web, you are organizing a set of objects, and the only thing Zope know how to do to distribute these objects is to package them up into pickles. -Michel

RE: [Zope] List All users with a given permission

The manager who modifes the user object could manually flush the cache? Subclass the user object with a ZClass to do this automatically?

Re: [Zope] Browser Sticky Fingers
by Jeff Rush 21 Oct '99

21 Oct '99

I'm still chasing the problem, and I got it to work at one point. There seems to be a related bug in Zope in OFS/Image.py, where the conditional test for "modified since X" is backward: ---- cut here ---- ms=REQUEST.get_header('If-Modified-Since', None) if ms is not None: ms=string.split(ms, ';')[0] ms=DateTime(ms).timeTime() if self._p_mtime > ms: RESPONSE.setStatus(304) # Not Modified Since Then return RESPONSE ---- cut here ---- If the object's modification time is (>) than the directive, then it *has* been modified since that time, and the code should *not* return status 304. So I reversed it... And now it works -every other time-. In fact, if I just comment out the entire "If-Modified-Since" stuff, and let every image appear new, it also fails every other time. <grr> By failure, what I mean is that you bring up a GIF image in the browser, and hit reload (no SHIFT key). The first time it updates the image, the second time is receives an HTTP response Content-Length of zero. Under Netscape 4.61 under Linux (HTTP/1.1), this causes the browser to segfault if you then ask it to 'view the source' of that document. Under Netscape 2.02 for OS/2 (HTTP/1.0), it pops up a dialog box that it got an empty document. Under Netscape 4.04 for OS/2 (HTTP/1.1), it spins forever waiting for some data to arrive. And if I run it thru a proxy like Webdebug.py, for tracing, it hangs Webdebug.py, doing a read on a socket that never gets data and you can no longer access Webdebug's HTML logging features since it is blocked. <sigh> I've done two 20-hour days on this so I'm going to bed. If anyone knows the HTTP/1.x spec quite well and can tell me why "IF-MODIFIED-SINCE" request headers can't just be ignored (albeit w/performance hit) with no ill effects, I'd appreciate it hearing about it. Otherwise tomorrow it's into the RFCs... -Jeff Rush P.S. The other gotcha on this problem was that the Expires: header *MUST* be set to the "LAST-MODIFICATION* date. I tried stuffing the current date and the server's "DATE:" header into it with odd results. The time lag btw LAST-MOD and DATE was ~17 secs (human click response time) and the refresh would -fail- for those 17 seconds after an image was modified (browser would not even -ask- for the image), but then work after that (browser would then start sending IF-MODIFIED-SINCE requests). And the tip that holding down the SHIFT key while clicking refresh to bypass the cache was worth it's weight in gold. When I do that, the images -always- update correctly. Turns out doing that causes the browser to never send any IF-MODIFIED-SINCE requests, just simple GETs.

MySQL Database Adapter
by Liz 21 Oct '99

21 Oct '99

I'm trying to hookup mySQL database to Zope. I've tried everything. I've downloaded the latest DA. I've follow ALL of the README.TXT instructions. I've reinstalled all of the C libraries. I just can't compile the damn thing. Could someone out there please be kind and treat me like a two year old and explain in explicit, excruciating detail and how install the DA. I must've missed something simple that everyone else "just knows". I'm on a Debian/Apache box running Zserver with Zope 2.0.0 and Python 1.5.2. What are the versions of all of the other components I need? In what order do I install them? Thanks in advance, Liz Pelletier

ODP 0.03 release
by A.M. Kuchling 21 Oct '99

21 Oct '99

I realized that some things were accidentally left out of the ODP release -- such as the actual Zope product! Therefore, I've implemented the missing mk* commands, fixed various problems, added the Zope product as a .zexp file, and issued a 0.03 release. http://starship.python.net/crew/amk/zope/ODP.html -- A.M.

Having problems mirroring a Zope site with wget
by Itai Tavor 21 Oct '99

21 Oct '99

Hi, I need to create a static copy of a Zope site. I dealt with all the basic nuisances like using .html instead of _html, adding .gif/.jpeg to images, etc. and it works fine, except for 2 problems: 1. Images retain their full URL. wget downloads and stores images in the right places on the static copy, but doesn't modify the SRC from "http://my.zope.site:8080/some/path/image.gif". Is there a wget option I'm missing that will deal with this? 2. I'm using the VirtualHostFolder product to serve sub sites from a single Zope server. wget on a virtual site works fine, except for images. Given the following Zope site: / subsite/ - VirtualHostFolder index.html images/ some_image.gif some_folder/ index.html images/ another_image.gif wget http://subsite.zope.server:8080/ creates the following: / index.html some_folder/ index.html subsite/ images/ some_image.gif some_folder/ images/ another_image.gif And, again, wget fails to change the image SRC from the full URL. Again, it looks like the only way around it would be some wget trick I can't think of. The wget command I'm using is wget -r -nv -nH --no-parent http://zope.server:8080/subsite/index.html Thanks, Itai -- Itai Tavor -- "Je sautille, donc je suis." -- itavor(a)vic.bigpond.net.au -- - Kermit the Frog -- -- 'Supposing a tree fell down, Pooh, when we were underneath it?' -- -- 'Supposing it didn't,' said Pooh after careful thought. --
