FYI: Zope 2.6.1 beta 1 today...
by Brian Lloyd 10 Dec '03

10 Dec '03

Hi all - We're planning on releasing a Zope 2.6.1 b1 today, and I wanted to give the dev folks a heads-up and let people know the plan for getting to 2.6.1 final. The release today will contain some ZODB / ZEO fixes as well as the datetime fix and some other fixes added since 2.6.0. We will be having a "bug day" next Tuesday, and the goal will be that those fixes will also go into the Zope-2_6-branch to be included in a 2.6.1 beta 2 to be release hopefully around the end of next week. Assuming there are no issues with the b2 release, we'll plan on making it final a week or so after that for a late xmas present :) This schedule should also provide enough time for the valiant volunteers working on the 2.6.1 version of the Zope Book to finalize things for the release.

ZOPE + SSL
by Illarramendi Amilibia, Aitor 10 Dec '03

10 Dec '03

Hello all: Which is the best (or more used) solution at this moment for having Zope supporting SSL secure connections? ZOPE + Apache + Apache mod_ssl + openSSL + Virtual_Host(or similiar solution)? Is ok, but it is not a little bit contradictory to need to use a second Web Server for supporting the first one? Redirecting URLs, and all... Dunno, there would be a day where ZOPE could have it's own support? ZOPE + OpenSSL + M2Crypto + SWIG? (this one rewrites Zserver parts) Is a little bit tricky to handle with the building, and i've found many exception problems when using it, especifically in BIO access types. Looks like the error handling is not very improved. ZOPE + OpenSSL + pyOpenSSL? This needs to be integrated in ZOPE, as a product, or anyway. Is there a most used recipe or case study examples? The environment where i'm planning to do it could be directed to Win32 platform, and at least over Zope 2.6.1 release. Regards.

zopectl start not working on Mac OS X
by Jim Roepcke 09 Dec '03

09 Dec '03

We are planning on shipping Zope 2.7 with the Plone 2 installer for Mac OS X. I can start a Zope instance on Mac OS X 10.2.8 using $INSTANCE_HOME/bin/runzope, but not using $INSTANCE_HOME/bin/zopectl start. I'm using Python 2.3.2 built from source, and Zope was built using: ./configure --with-python=/Applications/Plone2/Library/Software/Zope270/Python/bin/ python --prefix=/Applications/Plone2/Library/Software/Zope270/Zope --optimize make make install (note, the same thing happens whether or not i use the --optimize option) This happens with b3 and Zope-2_7-branch from today. cd $INSTANCE_HOME ./bin/zopectl start > Traceback (most recent call last): > File > "/Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ > Startup/zopectl.py", line 215, in ? > main() > File > "/Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ > Startup/zopectl.py", line 198, in main > c.onecmd(" ".join(options.args)) > File > "/Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ > cmd.py", line 210, in onecmd > return func(arg) > File > "/Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ > Startup/zopectl.py", line 134, in do_start > ZDCmd.do_start(self, arg) > File > "/Applications/Plone2/Library/Software/Zope270/Zope/lib/python/ > zdaemon/zdctl.py", line 214, in do_start > os.spawnvp(flag, args[0], args) > File > "/Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ > os.py", line 543, in spawnvp > return _spawnvef(mode, file, args, None, execvp) > File > "/Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ > os.py", line 504, in _spawnvef > wpid, sts = waitpid(pid, 0) > OSError: [Errno 10] No child processes I added code to zdctl.py to print out the environment and the command line used in os.spawnvp. It is (including some environment variables I set before running it): SOFTWARE_HOME=/Applications/Plone2/Library/Software/Zope270/Zope/lib/ python INSTANCE_HOME=/Applications/Plone2/Sites/Testing PYTHONPATH=/Applications/Plone2/Library/Software/Zope270/Zope/lib/python CLIENT_HOME=/Applications/Plone2/Sites/Testing/var ZOPE_HOME=/Applications/Plone2/Library/Software/Zope270/Zope export SOFTWARE_HOME INSTANCE_HOME PYTHONPATH CLIENT_HOME ZOPE_HOME /Applications/Plone2/Library/Software/Zope270/Python/bin/python /Applications/Plone2/Library/Software/Zope270/Zope/lib/python/zdaemon/ zdrun.py -S /Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ Startup/zopeschema.xml -b 10 -d -s /Applications/Plone2/Sites/Testing/var/zopectlsock -x 0,2 -z /Applications/Plone2/Sites/Testing /Applications/Plone2/Sites/Testing/bin/runzope I get this output: > Another zrdun is already up using socket > '/Applications/Plone2/Sites/Testing/var/zopectlsock': > status=running > now=1070998107.721581 > mood=1 > delay=0 > backoff=0 > lasttime=1070998096.551084 > application=1152 > manager=1141 > backofflimit=10 > filename='/Applications/Plone2/Sites/Testing/bin/runzope' > args=['/Applications/Plone2/Sites/Testing/bin/runzope'] I've looked at the source and nothing is popping out as being obviously wrong. If you have any suggestions for ways I can debug this further I can go further on this. For now I think I'm going to have to stick with runzope... but I'd really like to be using zopectl start/stop/status instead. Jim -- Jim Roepcke Tyrell Software Corp <http://www.tyrell.com/>

Zope 2.7.0 b3 regressions
by Yuppie 09 Dec '03

09 Dec '03

Hi! Migrating a CMF Site from Zope 2.6 to Zope 2.7.0 b3, I stumbled over these two Zope 2.7 issues: 1.) absolute_url(relative=1) behaves different ---------------------------------------------- 'relative' was changed from 'relative to site object' to 'relative to server root'. This is an API change and breaks Products like CMF. See <http://zope.org/Collectors/Zope/809> I propose to revert this change. 2.) reindexIndex not 100% backwards compatible ---------------------------------------------- CMF's CatalogTool inherits from ZCatalog and overrides catalog_object. Zope's reindexIndex fails because CMF doesn't implement the new catalog_object API. See <http://zope.org/Collectors/Zope/1134> I propose to add a capability check in reindexIndex. I'd volunteer to fix these issues in CVS as proposed, but maybe the people who made these changes still feel responsible for their code or there are objections regarding the proposed fixes. Any feedback is welcome. Cheers, Yuppie

WebDAV Collection/Resource Chameleon Question
by Eric Roby 09 Dec '03

09 Dec '03

We are trying to make a 'folderish' (WebDAV Collection) class appear as a WebDAV Resource to WebDAV clients. I won't go into the reasons why we want to do this unless someone is interested. We have made several attempts at this but have been unsuccessful to date. Rather than go into all the gory details about what we have tried I am asking if anyone could tell me if it is even technically possible to trick the WebDAV machinery (server/client) into treating this class in this way? TIA Eric

Zope is, generally speaking, *very* extensible -- see for example the long list of 3rd pary add-on products at http://www.zope.org/Products I think Python is one of the greatest strengths of Zope. Its not only a modern full-fledged OOP language, comes with great libraries (see http://python.org/doc/current/modindex.html, and has even more to download separately) but is simply a joy to program in. Bruce Eckel put it very nicely IMHO: http://mindview.net/FAQ/FAQ-012 ) Also see: http://csdl.computer.org/comp/mags/co/2000/10/rx023abs.htm http://www.cis.udel.edu/~silber/470STUFF/article.pdf http://www.twistedmatrix.com/users/glyph/rant/python-vs-java.html There are good networking modules in the standard Python distribution; image manipulation can be done with eg.

Newbie Question
by Aaron Paxson 08 Dec '03

08 Dec '03

I hope I'm posting to the right mailing list. There were so many to decide from. I've just been introduced to Zope, and am curious on how it will fit into my company's plans. I'm currently learning Java, and was starting to learn the RedHat Web Application Framework. I've found Zope in an article on the web, and started to look into it. It looks to be just as scalable, but I'm curious on how extensible it is, as well as, it's power in a corporate environment. For example, how extensible is it, to modify the security module and have it authenticate against LDAP? (I don't want all my users to remember yet another password) Also, how powerful is Python as compared to Java? Since it uses a native compiler, it stands to reason that it would be faster than Java, but what of it's objects and packages? (i.e. Does it have an image manipulation package, or networking packages?) I must say, seeing the documentation and books alone, tells me the product is good, and something I can learn. I see alot of "Hope for Zope" <grin, couldn't resist>, but I don't want to get into it, just to see if it doesn't fit into my plans. For those who want a couple of examples, I have 3 projects for our intranet/extranet/internet applications: 1). Images and cataloging (where, our development team can upload their images, and the intranet application will take that image and export it to a JPG to update the web catalog, and move the original file to our FTP site for our photographers. 2). Document Management (Uploading of files, and inputting data to index on those files for searching) 3). Obviously the usual (Content Management and Portals) which I'm sure Zope does a good job at. Thanks in advance!! Again, my apologies if there is a better list for this post. Aaron Paxson Network Operations Manager Decorative Concepts, Inc http://www.decorativeconcepts.com

apply()'s PendingDeprecationWarning
by Fred L. Drake, Jr. 05 Dec '03

05 Dec '03

Python 2.3, 2.3.1, and 2.3.2 generate a PendingDeprecationWarning when apply() is called. This is reasonable since apply() has been deprecated, but can be a real nuissance for code that intends to be portable to Python versions back to 1.5.2. Unfortunately, the logging package distributed with Python has that constraint (don't ask why, please; I really don't know!). Anyone watching the results of the test runs has probably noticed that these warnings are polluting the test output still, and aren't being triggered by Zope code. Guido has conceded that these warnings can be removed from Python, so I've removed them for the upcoming Python 2.3.3 release as well as for the future Python 2.4. Just thought everyone would be thrilled to know. ;-) -Fred -- Fred L. Drake, Jr. <fred at zope.com> PythonLabs at Zope Corporation
