dear zope gurus, i hope, this is the right place to post this: i'm trying to modify a modified ZSyncer product. The first modification implements bidirectional syncronisation. It simply exports any Zope object, transmitts it via XML-RPC and imports it remotely, or vice versa. The problem i'm trying to fix is that synced objects should have synced timestamps and not the original one vs. the importation time. My solution is to *ship* the modification time of the original object together with the object, but i don't know how to explicitly change the timestamp of the freshly imported one. the essential part of the code is the following method, which imports the object -- it gets the object data, the path of the object and its modification time (see "# change modification time"): def manage_addXMLRPC(self, data, obj_path, mod_time=0, add_in=1): """ Adds / imports an object """ # make sure we always get a string or a list if type(obj_path) == type('string'): obj_path = string.split(obj_path, '/') # object lets try finding the parent try: parent = self.restrictedTraverse(obj_path[:-1]) except KeyError: return 404 # lets check they are allowed to do this c = getSecurityManager().checkPermission allowed = 1 for perm in ['Delete objects', 'Import/Export objects']: if not c(perm, parent): allowed = 0 if not allowed: return 403 # if there is one there already, delete it if obj_path[-1] in parent.objectIds(): parent.manage_delObjects([obj_path[-1],]) # lets do it if add_in: # fake a file using StringIO file = StringIO() file.write(self._decode(data)) file.seek(0) # now import new = parent._p_jar.importFile(file) parent._setObject(new.getId(), new) # change modification time my_obj = self.restrictedTraverse(obj_path) my_obj._p_mtime = mod_time # yay! return 200 i tryed to change the modification time via the _p_mtime attribute (because bobobase_modification_time() returns it normally), but it doesn't work. I played around with it but there was no enlightenment. i guess its a secret of the ZODB. please help me to get on the right path. yours faithfully. Andreas Hoelzl
