inituser problem
by Chris Withers 14 May '05

14 May '05

Hi, I have a problem with the code in AccessControl.User.UserFolder._createInitialUser. It creates a user under what I feel are fairly bizarre circumstances. I feel it should simply use inituser if it's there and the user in it doesn't already exist in the root acl_users. Either that, or it should overwrite any user if the inituser file exists. The weird special case of one user being in the root acl_users seems extremely counterintuitive. What do other people feel? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Refresh and dumping the cache
by Dylan Jay 13 May '05

13 May '05

When performing a refresh I've read that the cache gets dumped. I've noticed after a refresh the reference counts to objects don't go down. Basically the entire cache seems to be leaked. Is this by design or is it a bug? -- Dylan Jay --- http://www.meetmemap.com - makes giving directions easy http://www.pretaweb.com - Update-it-yourself, low cost websites http://www.eatmanifesto.com - against all dumbing down of food Y!:dylan_jay ICQ:520341 MSN:djsq@hotmail.com Ph:+61423198306

DateTime, strftime and TimeError
by Santi Camps 13 May '05

13 May '05

Hi all, I think its known that using strftime method of DateTime module with dates <= 1900 or >= 2038, a TimeError is raised. For instance: >> d = DateTime('2045/30/01') >> d.strftime('%d/%m/%Y') DateTime.DateTime.TimeError: The time 2369343600.000000 is beyond the range of this Python implementation I've read that the reason was a validation to avoid int overflows. I think this could be fixed using datetime module (new in python 2.3) instead of old time.localtime Do you think its a good idea ? Can I provide a patch that way ? Thanks Santi Camps

copyzopeskel.py patch
by Dale Hirt 12 May '05

12 May '05

Hi all, Wonderful product, more than appreciate all the hard work that has been put into Zope and all the various products that are out there. Came across a small issue, and wrote a quick patch for it. Didn't know who to send it to, so I thought I'd send it here. When creating a new zope instance, using mkzopeinstance.py, and having my files under Subversion, copyzopeskel.py also took across my .svn directories. So I created the small patch below to stop that. Makes it a little more flexible for adding in new types, and since you've switched to Subversion anyways, makes sense to add it in there. Again, thanks for your time, Dale Hirt Index: copyzopeskel.py =================================================================== --- copyzopeskel.py (revision 30342) +++ copyzopeskel.py (working copy) @@ -186,12 +186,12 @@ print >>sys.stderr, msg sys.exit(1) -CVS = os.path.normcase("CVS") +CVS_DIRS = [os.path.normcase("CVS"), os.path.normcase(".svn")] def copydir((targetdir, replacements, uid, gid), sourcedir, names): # Don't recurse into CVS directories: for name in names[:]: - if os.path.normcase(name) == CVS: + if os.path.normcase(name) in CVS_DIRS: names.remove(name) elif os.path.isfile(os.path.join(sourcedir, name)): # Copy the file:

It seems to work around an issue with connect() on Windows. But I still believe it was wrong to change the 'inet_address' datatype in ZConfig. Cheers, Yuppie

Zope 2.8 on hold
by Andreas Jung 09 May '05

09 May '05

Hi, in agreement with Jim Fulton and Brian Lloyd we decided to put the Zope 2.8 release on hold for now. There are several open issues related to running Zope on Windows (building, startup problems). Since we need to have a stable source code release and a stable windows release in sync, the next beta 2 will appear as soon as the major issues are fixed. This is maybe a good point for advanced Windows programmer to help out *wink* Andreas

relocating Zope 2 core interfaces - a proposal
by yuppie 09 May '05

09 May '05

Hi again! As discussed two days ago, I started working on integrating Five interfaces closer into Zope 2.8. I believe I understand the problem better now and like to propose a different way to resolve it: Current State ============= Five (now part of Zope 2.8) ships with one big interfaces.py file that contains z3 interfaces for Zope 2 core classes. (There are also some five specific interfaces in that file, but they are not subject of this proposal.) interfaces.zcml states that Zope 2 implements these interfaces, but there are no tests to verify that and in fact many of these interfaces are broken in Five 1.0. (Yesterday I checked in some fixes to the Five trunk.) So if they are used at all in Five products, they are only used as marker interfaces, not to verify implementations. I grepped through CMFonFive, SilvaDocBook and SilvaFlexibleXML: None of them use these interfaces. Goals ===== Step by step, Zope 2 should move to z3 interfaces. Where z2 interfaces exist, these should be improved and bridged to z3 interfaces. Missing interfaces should be added as z3 interfaces. Instead of maintaining competing interfaces, Five should support that process. Interface locations are identifiers, so first of all I want to get these locations right before Zope 2.8 is released. Z3 interfaces should be located in an 'interfaces' module of the corresponding package. In the Five package they are unmaintainable. So e.g. instead of Products.Five.interfaces.IObjectManager Products.Five.interfaces.IWriteLock we would have OFS.interfaces.IObjectManager webdav.interfaces.IWriteLock Proposed Solution ================= 1.) Adding ZCML that bridges existing z2 interfaces into the 'interfaces' module of their package. [Zope 2.8.0] 2.) Copying z3 interfaces from Five.interfaces to the 'interfaces' module of the corresponding package. Marking those in Five as Zope 2.7 backwards compatibility cruft. [Zope 2.8.0] 3.) Doing the same for Zope 2.7 with monkey patching code. [Five 1.0+] 4.) Making interfaces.zcml point to the new locations. [Five 1.0+] 5.) Adding unit tests that verify interfaces and implementations. [Zope 2.8.0] Risks ===== I can't see a way to provide backwards compatibility for Products.Five.interfaces.*, but as explained above I'm hopeful this doesn't break many Five products. Any comments? Cheers, Yuppie

[Andreas Jung] > At least the following are important (besides the problem with the > Winbuilder) What WinBuilders problem? I keep hearing there's "a problem" there, but don't know what it is -- and I had no problem using WinBuilders for Zope 2.8. Note that these two aren't about Zope 2.8, they're about Zope 2.7.6: > http://www.zope.org/Collectors/Zope/1763 > http://www.zope.org/Collectors/Zope/1711 Both appear to be due to that Zope 2.7.6 on Windows shipped with a wrong (too old) version of pywin32, and continued to repackage pywin32 in the old (certifiably insane <0.7 wink>) "flat" way. Mark Hammond submitted patches to install a correct version of pywin32, and in a correct way. Those patches were incorporated into WinBuilders, so it's hard to understand how Zope 2.7.6 on Windows got built the way it did. Can only guess the installer was built using an out-of-date WinBuilders checkout, with an out-of-date pywin32, applied to an up-to-date Zope checkout.
