oh boy [id,getId() madness]
by Romain Slootmaekers 12 Jun '03

12 Jun '03

Yo, I have an error in this code fragment: ------------- fragment ---------- for childObject in container.objectValues(): id=childObject.getId() childObject2=container[id] # sometimes gives a KeyError ???? #... ------------- /fragment ---------- So it means that there are contained objects with an getId member that returns something different than the key that is used for these objects in the container object. As it turns out, I indeed have such objects in my ZODB, and they cause all kinds of problems (fe, you can't rename them with the management interface) The questions are: - has anyone else experienced this ? - what could be causing this ? TIA, Romain.

serialization with Ape
by cs＠comlounge.net 11 Jun '03

11 Jun '03

Hi list! :) I am just playing around with Ape (very cool, btw :) and wondering how it can be used from the outside, e.g. not controlled by transactions. Main idea is to manually copy parts of the ZODB to the filesystem (from a product). I first tried the transaction based process, as I found it in some tests: # init (createMapper imported from fsmapper) root_mapper, conns = createMapper(fspath) conn=conns['fs'] resource = StaticResource(root_mapper) storage = ApeStorage(resource, conns) db = ApeDB(storage, resource) get_transaction().begin() # test object to store object = getattr(self,'standard_template.pt') c=db.open() app=c.root()['Application'] id=object.getId() app._setObject(id,object.aq_base,set_owner=0) get_transaction().commit() db.close() which actually stores it but does not seem to me that clean because of all the transaction stuff. I would here then recursively run through all the objects and do that inside one transaction. I then detected the fascades in io.py which I tried to use (dunno if they're thought to be used for such a purpose actually ;-): root_mapper, conns = createMapper(fspath) ei=ExportImport(root_mapper,conns) ei.exportObject(object) Unfortunately this results in an exception Type: MappingError Error Value: Path keychains require a name So can maybe somebody point me to the easiest way to serialize an object using the fsmapper (Shane? ;-) ? I am also interested in reading a serialized object from the fs again and writing it to the fs. Also I wonder if I need to delete objects which have been modified before another export or if there's a possibility to just change it). (and the best would be of course some simple methods for reading/writing a whole directory recursively. I don't know if something like this is already in there somehow or how it works internally.. seems all a bit magic to me ;-) So thanks in advance if anybody can help me :) cheers, Christian -- COM.lounge http://comlounge.net/ communication & design info(a)comlounge.net

what is manage_workspace supposed to do?
by Oliver Bleutgen 11 Jun '03

11 Jun '03

I've a problem with a product I'm writing and the way manage_workspace works. There's this code in App/Management.py: def manage_workspace(self, REQUEST): """Dispatch to first interface in manage_options """ options=self.filtered_manage_options(REQUEST) try: m=options[0]['action'] if m=='manage_workspace': raise TypeError except: raise Unauthorized, ( 'You are not authorized to view this object.') (*) if m.find('/'): raise 'Redirect', ( "%s/%s" % (REQUEST['URL1'], m)) return getattr(self, m)(self, REQUEST) My question is about the marked block. I'd guess that the intent is to send a redirect if m (== options[0]['action']) contains a '/'. But m.find('/') evaluates to false only if m[0] == '/', otherwise it yields either -1 (which is true), if there's no '/' in m, or something greater 0, if there's a slash after the first char. Is this intended behavior or a bug? cheers, oliver

Versions: should they die?
by Paul Winkler 10 Jun '03

10 Jun '03

To anyone not following the "Problem committing zope 'version' objects" thread on zope(a)zope.org: It's been proposed that Versions should be at least stamped in the ZMI with big warnings, or possibly disabled altogether. Numerous users have been bit by the fact that versions basically do not work as advertised, leading in various cases to zodb corruption or work that can't be saved. There are other security issues that Oliver Bleutgen raised privately which I won't state here. Comments? Could we get at least some warnings in the ZMI before 2.6.2 final? -- Paul Winkler http://www.slinkp.com Look! Up in the sky! It's THE COSMIC! (random hero from isometric.spaceninja.com)

RE: [Zope-dev] Versions: should they die?

If I remember correctly, though, there was still a lot in question about legitimate use cases. The web-services cluster-safety use-case I sketched out here (http://mail.zope.org/pipermail/zope3-dev/2002-October/003112.html) is still (perhaps) a valid case, but ONLY in a very-carefully constructed application (and even that case leaves me wanting a better app-level way to do it). I think I agree with the feeling that versions should stay in ZODB, but be depreciated/marked as "official evil" in ZMI.

Image.py:File._upload_data
by Chris Withers 10 Jun '03

10 Jun '03

It would appear that _read_data only returns a single Pdata object if you chuck it a large string rather than the linked list of Pdata objects it would if you chucked it a FileUpload instance. Surely it should return a linekd list of Pdata objects in either case?

RE: DBtab and BDBStorage
by Andrew R. Halko 10 Jun '03

10 Jun '03

Hey Shane, After I converted a Plone folder into its own ZODB, I believe it still has the contents of the old site in it while loading the one folder from the new database. So, I copied data.fs to be files.fs and then deleted in the plone interface, created the mount point and it came back. Loading from the files.fs The thing is, all the old content from data.fs is still in files.fs just sitting dormant and inaccessible. This makes me wonder if the old stuff from my files folder is sitting dormant in data.fs? Do you know of any way to make fix these databases so they don't have the areas that they are not being used for anymore? Thanks! Andrew R. Halko
