Write a bug report, attach the patch and for a quicker response inform a "Five" maintainer about the "bug+solution". I am not sure however, that this will be sufficient: "Zope 2.9" is no longer an actively maintained version; maybe the maintainers think there are more important tasks that to fix problems with older versions. -- Dieter

Anyone know of a tool to restore/cleanup/reset security/role settings?
by Ross Patterson 01 Dec '08

01 Dec '08

Does anyone know of an existing tool for restoring all security settings/rolemaps from the ground up? Obviously I can use rolemap.xml where applicable and update workflow security. I want to first restore the Zope root to code defaults and restore the whole hierarchy to just acquire. I'm going to write something myself if not, but I thought I'd see if there was anything out there. Ross

You are right. Almost surely, you see a "Five" bug: "Five", too, should respect "enable-product-installation". You can see the right transaction handling in "OFS.Application.install_product' -- somewhere near the buttom of this function. Maybe, you correct "Five" accordingly. >Any idea why this is happening to me >and doesn't seem to be a common problem >others come across? "ConflictError"s are apparently nondeterministic errors -- they only occur when concurrent transactions conflict with one another. Apparently, in your setup, the conflict probability is especially high (maybe because it is especially expensive to register your package). In principle, others are threatened as well if the are using "registerPackage". I do not have Zope 2.9 with its "Five". In Zope 2.11, the "Five" code appears to have been cleaned up. This means, upgrading to Zope 2.11 may be another option for you. -- Dieter

by Mr SZ 29 Nov '08

Hi All, I can now create BTreeFolders and add,remve items to and from it but how and where does zope store my folders,does the id indicate the folder I'm storing in? This is in an external method: def test3(): f = BTreeFolder2('sufest') f2 = BTreeFolder2('somefolder') f3 = BTreeFolder2('somefolder2') f._setObject(f2.id, f2) f._setObject(f3.id, f3) uniq_id = f.generateId() obT = OOBStuff(uniq_id,{'a':1,'b':2}) f._setOb(uniq_id, obT) lst = f.objectItems() return lst def test4(): if 'suftest' in aq_parent.objectIds(): return 'True' class OOBStuff(BTreeFolder2): meta_type ='OOBStuff' def __init__(self, oid,dict_to_add): super(OOBStuff, self).__init__(oid) self.item = OOBTree() self.item['Auth'] = dict_to_add def return_Tree(self): return self.item Running test4 gives this error: Error Type: AttributeError Error Value: 'builtin_function_or_method' object has no attribute 'objectIds' Also, how come my BTFolder didn't show up anywhere in the ZMI?
