changing permissions in python
by Garry Saddington 14 Oct '08

I have been searching everywhere for the correct syntax to use to change permissions on a dtml method from a python script. I know it could be using manage_changePermissions() but exactly how can I call it on any method. Regards Garry

Old zope instance migration to Ubuntu 8.04?
by Mike Elliott 14 Oct '08

14 Oct '08

Hi - I have an old instance of Zope - I'm not sure just how old but at least four years (maybe six or seven, I don't know) - which has been running on a server which is now no longer functional. I'd like to migrate to a new server running Ubuntu 8.04.1 but the old code doesn't run anymore. I have a full backup of the system and would be quite content to get it running under the current Ubuntu zope distribution on the new server but would like some advice as to how best to proceed. Simply putting the existing zope directory structure on the new machine and trying to start it up no longer works - presumably due to differences in Python versions - but I don't actually know that. I have a high school field hockey team, an Indian Princess group and a couple of other groups with Plone sites on the old server and they'd like to see their stuff again. Any suggestions as to the best way to handle this? Cheers --

howto talk to a zodb while zope is running
by Paul Gevers 13 Oct '08

13 Oct '08

Hi, I maintain several websites where we rely heavily on file-system files to serve images and movies. We have a user interface in Zope to manage the files, based on the "external file" product. Users can upload files via webdav to the filesystem and I am synchronizing Zope by using inotify (Linux OS kernel tool that triggers on changes on the file system). At the moment I use a http request to the localhost to tell Zope that the filesystem has changed, but when a lot of files are created in a short time the updating is too slow. Is there a faster way to talk to the zope database than via a http request while zope is running? I tried to find something useful on the net, but was buried in too many pages which are not really relevant. With kind regards, Paul

Zope 2.x for Py 2.6 as 64 bit Windows application?
by martin.gfeller＠comit.ch 12 Oct '08

12 Oct '08

Dear all We're contemplating the move of our Zope 2.x application to 64-bit Windows. We rely on a few add-on packages, notably PyWin, which has 64-bit support for Py 2.6 only. I'd be grateful for a rough idea on when there could be a Zope 2.x release working with Python 2.6 as a 64-bit Windows application. Jim Fulton wrote on 19 Sep 2008 top ZODB-Dev: > We (ZC) are moving to 64-bit OSs.

However, Jim told me that he neither using Zope 2.x nor Windows and directed me to this list for my question.

webdav upload - controlling type, hook
by Jakob Schou Jensen 11 Oct '08

11 Oct '08

When uploading a file to the zope db using the webdav interface zope select on object type based on the file contents (or extension?). For instance when I upload a html file it becomes a DTML document. Is there any way to control what type of object is selected? Additionally I would like to execute some script code after a webdav upload. Is there any way to get a hook or callback or something similar? Thanks, Jakob

Zope hangs
by Nico Grubert 11 Oct '08

11 Oct '08

Hi there in the last days my Zope server seems to hang and the CPU is almost every time at 100 %. I installed DeadlockDebugger and see a lot of these entries: ----------------------------------------------------------------------------- File "/usr/local/Zope-2.10.5/lib/python/OFS/Traversable.py", line 288, in unrestrictedTraverse return obj File "/usr/local/Zope-2.10.5/lib/python/ZODB/Connection.py", line 767, in setstate raise File "/usr/local/Zope-2.10.5/lib/python/ZODB/Connection.py", line 820, in _setstate obj._p_serial = serial File "/usr/local/Zope-2.10.5/lib/python/ZODB/serialize.py", line 605, in setGhostState obj.__setstate__(state) File "/usr/local/Zope-2.10.5/lib/python/ZODB/serialize.py", line 597, in getState return unpickler.load() File "/usr/local/Zope-2.10.5/lib/python/ZODB/serialize.py", line 471, in _persistent_load return self.load_oid(reference) File "/usr/local/Zope-2.10.5/lib/python/ZODB/serialize.py", line 537, in load_oid return self._conn.get(oid) File "/usr/local/Zope-2.10.5/lib/python/ZODB/Connection.py", line 225, in get return obj File "/usr/local/Zope-2.10.5/lib/python/ZODB/FileStorage/FileStorage.py", line 562, in load self._lock_release() File "/usr/local/lib/python2.4/threading.py", line 109, in acquire return rc ----------------------------------------------------------------------------- I am wondering what the last line File "/usr/local/lib/python2.4/threading.py", line 109, in acquire return rc does exactly mean. Are the threads blocked? My configuration: -Zope 2.10.5 running with 8 threads on a 2-CPU machine with 8 GB of RAM -Python 2.4.4 -LDAPUserfolder -Silva CMS 2.0.8 -ZODB size: ~6 Gbyte -Only 6-10 people work in the CMS and no public access (spy bots, crawlers) access the Zope server Regards Nico

VHM / traverse subpath interaction bug?
by Chris Withers 11 Oct '08

11 Oct '08

Hi All, I've tried this on Zope 2.8-2.11.1 and it behaves the same on all but feels like a bug. I wonder if anyone else agrees or, better yet, knows what's going on here... So, add a Script (Python) called test in the root on a Zope instance running on port 8080 and in it put: return repr(traverse_subpath) Now go to: http://localhost:8080/test/x/y/z ..you'll get: ['x', 'y', 'z'] ...which makes sense. Now, if you have a VHM called virtual_hosting (as it normally is) if you go to: http://localhost:8080/VirtualHostBase/https/example.com:443/test/VirtualHos… ...you'll now get: ['virtual_hosting', '/', 'x', 'y', 'z'] ...which doesn't seem right to me. Worse yet, if you go to: http://localhost:8080/VirtualHostBase/https/example.com:443/test/VirtualHos… ...you get: ['virtual_hosting', '/something', 'x', 'y', 'z'] Anyone got any ideas as to what's going on here? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
