two-phase-commit question
by Kapil Thangavelu 30 Sep '00

ZOPE_HOME/lib/python/Shared/DC/ZRDB/TM.py Glancing over the Transaction TM mixin class... i noticed a line commit=tpc_abort=tpc_begin i can understand tpc_begin=commit, but the abort seems strange. if an abort happens in the two phase commit the equality doesn't make sense to me. whats going on here? Is this meant to be overidden? TIA Kapil

When I execute your code (Zope 2.2.2), I get the expected result. For me, it seems, that you have a variable named "row_index" in "REQUEST.environ" with value "0". According to source documentation (ZPublisher.HTTPRequest), "environ" has precedence over "other" (where ".set" places it definition). Try a different name with a very low change of being already used: e.g. "row_index" --> "xyz123456". Dieter

why cant i rename an object from an external method
by Andy McKay 29 Sep '00

29 Sep '00

Heres a treat. I'm trying to write an external method to rename objects. I have approx 10,000 to rename so a script would be nice. No problem I thought, imitate a forms manage_renameObject and CopySupport.py can do the work. Rename works fine from the web form, but not from a script. (ASPNTools.getsomeobjectsfromstring returns a bunch of objects, Ive tried replicating this with resolve_url and get different namespace error, could this be a clue?). Heres my script: def search(self, REQUEST=None): l = ASPNTools.getsomeobjectsfromstring(self, REQUEST['path'], REQUEST) for obj in l: ob = obj.aq_parent # get the folder ob.manage_renameObject(obj.id(), 'Foo') return 'renamed' Here's my problem: The object 100BASEFX does not support this operation .... File d:\p4\Zope-dev\lib\python\Products\ASPN/Extensions/foo_rename.py, line 6, in search (Object: 100BASEFX) File d:\p4\Zope-dev\lib\python\OFS\CopySupport.py, line 288, in manage_renameObject (Object: Traversable) File d:\p4\Zope-dev\lib\python\OFS\CopySupport.py, line 406, in _verifyObjectPaste (Object: Traversable) Copy Error: (see above) There surely must be simple way of doing this so I dont have to resort to writing a Perl script to imitate the browser, please! Thanks in advance as ever. -- Andy McKay, Developer. ActiveState.

Have you had a look at the ExtFile Product (http://www.zope.org/Members/MacGregor/ExtFile)? It basically does all the things you want to achive with the PersistentBlob (i.e. storing files externally and making them accessible for external processes), except that it's not that deeply integrated into the Zope machinery and stores the files only in the file system and not in an RDBMS (which nevertheless could be implemented). Cheers, Gregor!

ZPL HowTo?
by Lalo Martins 29 Sep '00

29 Sep '00

We wished to release the new development version of HiperDom under the ZPL, but we figured it wouldn't be that simple, as the license text is all littered with "Digital Creations". Is it just a matter of s/Digital Creations/Hiperlógica/g? Is this even legal? (This message is mostly rethorical, because we already decided to just release it under the MIT-X11 license anyway, but I feel this question should be discussed if people want to release stuff under the ZPL in the future.)

Fix for Can't Change Image & File Security Settings in Zope 2.2.x
by Chris Withers 29 Sep '00

29 Sep '00

Hi, You may, like me, have noticed that you can't change security settings on Image and File objects in Zope 2.2.x. This is because the __call__ method of these objects was removed by the appropriate bit of __ac_permissions__ wasn't taken out. The patch in the PS fixes this... cheers, Chris PS: =================================================================== RCS file: /cvs-repository/Zope2/lib/python/OFS/Image.py,v retrieving revision 1.105.2.12 diff -r1.105.2.12 Image.py 169c169 < 'getContentType', '__call__', '')), --- > 'getContentType', '')), 450c450 < 'getContentType', '__call__', '')), --- > 'getContentType', '')),

Soft links again
by al028823＠alumail.uji.es 29 Sep '00

29 Sep '00

Hi all, First, I'm using Zope 2.2.1 (Debian package). I've been trying to implement zope objects that behave like unix soft links. The message http://lists.zope.org/pipermail/zope-dev/2000-July/005963.html by Shane proposes an implementation based in the __of__ method: class SoftLink (SimpleItem): def __init__(self, path): self.path = path def __of__(self, parent): ob = self.restrictedTraverse(self.path) return getattr(ob, 'aq_base', ob).__of__(parent) but it fails when I try to create an instance: Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addImportedSubject) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_addImportedSubject) File /var/lib/zope/Products/LLEU/subjects.py, line 1129, in manage_addImportedSubject (Object: Traversable) File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 250, in _setObject (Object: Traversable) File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 236, in _getOb (Object: Traversable) AttributeError: A00 A little of debug shows that the object has been added (line 249, see below), the exception raises when it tries to get the object (line 250). The hasattr function (line 234) returns false but the object has been added (it's in the __dict__) attribute and its __off__ method is called when the hasattr function is called. What I'm doing wrong? Thanks, david ObjectManager.py: class ObjectManager( ... def _setOb(self, id, object): setattr(self, id, object) def _delOb(self, id): delattr(self, id) def _getOb(self, id, default=_marker): 234 if not hasattr(aq_base(self), id): if default is _marker: 236 raise AttributeError, id return default return getattr(self, id) def _setObject(self,id,object,roles=None,user=None, set_owner=1): v=self._checkId(id) if v is not None: id=v try: t=object.meta_type except: t=None self._objects=self._objects+({'id':id,'meta_type':t},) # Prepare the _p_jar attribute immediately. _getCopy() may need it. if hasattr(object, '_p_jar'): object._p_jar = self._p_jar 249 self._setOb(id,object) 250 object=self._getOb(id)
