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?

New-style ExtensionClass
by Jim Fulton 02 Dec '03

02 Dec '03

I've started work on a new-style ExtensionClass. This is a port of ExtensionClass to new-style classes. This will provide a number of advantages: - Use of new-style class features (e.g. descriptors) in Zope objects. - Support for cyclic garbage collection. - Ability to use new-style classes as base classes of Zope objects. - Use of a version of ZODB that supports non-ExtensionClass classes. - Pave the way for sharing code between Zope 2 and Zope 3. I hope I can merge this into the Zope 2 head in a week or two. This is a rather deep change and it is likely to cause some instability on the CVS head for a while. I'm doing this now, rather than later, to give us plenty of time to find and fix problems before a Zope 2.8 release. Speaking of Zope 2.8, Jeremy Hylton has suggested that, perhaps, Zope 2.8 should be a release that provides *only*: - New-style ExtensionClass, and - ZODB 3.3, featuring multi-version concurrency control, plus any features that have been added to the head since the Zope 2.7 branch was created. This idea is pretty appealing to me. I wonder what others think of it. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!
