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

Thanks for resonding, even though there was a better list! I've got some fantastic replies, and was overwhelmed with the answers!

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

Zope-2.7.0-b3-win32.exe not beta 3?
by Yuppie 04 Dec '03

04 Dec '03

Hi! I'm a bit confused: Can anybody confirm that the Windows installer at <http://zope.org/Products/Zope/2.7.0b3/2.7.0b3/Zope-2.7.0-b3-win32.exe> contains beta 2 code? I first thought the Version number visible in the Control Panel wasn't updated, but now I stumbled over files that don't have the beta 3 fixes. Cheers, Yuppie

DateTime stftime and TAI based timezone is broken or is it?
by Brad Clements 03 Dec '03

03 Dec '03

Yesterday I switched my Linux machines to use clockspeed 0.62 and therefore had to switch to the right/EST5EDT timezone. Today my client calls rather upset that lots of data has disappeared from his database, etc.. So while I have found and fixed a bunch of timezone conversion problems in my code, I'm stumped by DateTime.strftime(). I'm working with Zope 2.6.0 but the code is the same in 2.7.0b2 Basically, I get this situation: >>> dx '2003-12-01 00:00:00' >>> y = DateTime.DateTime(dx) >>> y DateTime('2003/12/01') >>> y.strftime("%a %b. %d") 'Sun Nov. 30' >>> y.strftime("%a %b %d %H:%M:%S") 'Sun Nov 30 23:59:38' >>> y.Time() '00:00:00' So, the DateTime object knows the correct year, month and day, it's mishandling of 'diff' in strftime is a problem. I can't quite figure out what the regex does in the code below, but diff is 22 seconds off from the "regular timezone offset". That's will be lost in the divide by 36. The timezone offset that _tzoffset calculates is wrong: >>> DateTime._tzoffset(y._tz, y._t) -18000 Because >>> y._tz 'US/Eastern' (but it should be 'right/EST5EDT') What's the best way for me to fix this? I'll submit a patch if I can get a clue. Btw, the timezone right/EST5EDT isn't in DateTime's timezone listing. Shouldn't Zope get this data from Python? I'll remark that Python doesn't know about the 'correct' offset either. >>> import time >>> time.tzname ('EST', 'EDT') >>> time.timezone 18000 Well now I'm stuck, I've set /etc/localtime and /usr/share/zoneinfo/posixrules correctly, and "date" returns the correct time. However even forcing TZ with Python 2.3 doesn't work correctly. sh-2.05b$ TZ="right/EST5EDT" python2.3 Python 2.3.2 (#2, Nov 6 2003, 10:44:39) [GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import os >>> os.environ['TZ'] 'right/EST5EDT' >>> import time >>> time.timezone 18000 >>> time.tzname ('EST', 'EDT') >>> time.tzset() >>> time.tzname ('EST', 'EDT') >>> time.timezone 18000 How does time.localtime() know the correct timezone offset, but time.timezone is not correct? >>> time.localtime(); os.system('date') (2003, 12, 1, 12, 55, 25, 0, 335, 0) Mon Dec 1 12:55:25 EST 2003 ----- DateTime.py def strftime(self, format): # Format the date/time using the *current timezone representation*. diff = _tzoffset(self._tz, self._t) format = re.sub('(^\|[^%])%z', '\\1%+05d' % (diff / 36), format) return strftime(format, safegmtime(self.timeTime() + diff)) -- Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax http://www.wecanstopspam.org/ AOL-IM: BKClements

DCWorkflow duplicated?
by Dorneles Treméa 03 Dec '03

03 Dec '03

Hi there, I noticed we've two 'trees' for DCWorkflow: - http://cvs.zope.org/Products/DCWorkflow - http://cvs.zope.org/CMF/DCWorkflow The current diff between HEAD of the two versions are attached, the changes are minimal. I've looking for the reasons of split, but I don't found anything related... That said, I ask: is really necessary to maintain both trees? PS: I guess here's the right place to make this question. If I'm wrong, please point me to the right place... ;-) Best regards, -- Dorneles Treméa Caxias do Sul - RS - Brasil +55 54 9114 9312 - UIN: 2413568 X3ng Web Technology <http://www.x3ng.com.br> -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCS/IT d- s:->: a24 C+++ UBL++++$ P--- L++ E-- W+++ N++ o?
