2.10 and ZClasses
by Allen Schmidt Sr. 26 Feb '08

26 Feb '08

We are still running 2.7.5 but really want to upgrade. Changes.txt in 2.10.5 state ZClasses are deprecated. CAN they still be used?? Not at all or just not recommended and why? What is the highest version we can safely upgrade to then? Thanks Allen

zcatalog, brains & keywordIndex
by Stefano Guglia 26 Feb '08

26 Feb '08

Hello everybody.. I have to index some data from a mysql query recordset and all works OK but..I added a keywordIndex to store (with the same url) multiple values related to the above recordset. It seems I cannot use brains (query results are strings). Probably a newbie question, but I really do not know how to update a keywordIndex starting from a list..Any help (+sample code pls :-)) ? Thanks, Stefano.

Need Server
by Victor Subervi 26 Feb '08

26 Feb '08

Hi: I am out of business and I need someone to host a client's site (for which they will obviously pay). Requires Zope 2.78 and ZMySQL. Have everything you need. I would need to get into the ZMI to set things up, but don't need server access. Please write me off-list. TIA, Victor

Zope Calendar Product?
by Cliff Ford 25 Feb '08

25 Feb '08

Hello friends, I have been away from Zope for a while. I have a Zope 2.9.3 installation (no CMS or Plone) for which someone has requested a Calendar application. From the Zope sites it is not clear whether any suitable product is available. Could anyone recommend something? Alternatively, might it be an idea to use a stand-alone Calendar application and plug it into an I-frame? Cliff

If I understand well, brains are there just for this purpose. I'm just a beginner in zope, so please let me know if there are more effective ways to do that.

Frequent Zope crashes (Zope 2.9.8)
by Paul Brettschneider 23 Feb '08

23 Feb '08

Hello, my Zope 2.9.8 instance crashes up to 6 times per hour. This is very unfortunate since the constant restarting brings performance to its knees. It runs under Linux in 64 bit mode on an AMD64 . I managed to catch two backtraces with gdb (see end of the mail). Both backtraces show a crash in cc_oid_unreferenced(ccobject *self, PyObject *oid) in persistent/cPickleCache.c: Either in line 576: v = PyDict_GetItem(self->data, oid); or in line 607: Py_DECREF((ccobject *)((cPersistentObject *)v)->cache); v and v->cache seem to point to heap: (gdb) print v $1 = (PyObject *) 0x5f8920 (gdb) print ((cPersistentObject *)v)->cache $2 = (PerCache *) 0x613620 Always called from Per_dealloc(cPersistentObject *self) in persistent/cPersistence.c in line 578: cPersistenceCAPI->percachedel(self->cache, self->oid); Is this a known issue?

zope and postgresql
by madhangc 22 Feb '08

22 Feb '08

Dear all, I'm new to zope. I have planned to use zope with postgresql in a windows environment. I have installed zope 2.x, python 2.4, mxtools, psycopg2.0. I have no idea to proceed from here. I have ZpsycopgDA downloaded, but i don't no how to install it and use it in zope. It is very urgent that i have to finish a project. Can some one give some idea on how to connect zope and postgresql. I prefer a good tutorial which teaches how to use zope with pgsql. Thanks in advance. \madhan -- View this message in context: http://www.nabble.com/zope-and-postgresql-tp15631023p15631023.html Sent from the Zope - General mailing list archive at Nabble.com.

dtml-let and product
by Wayne Volkmuth 22 Feb '08

22 Feb '08

I have a simple test Zope product inheriting from Cacheable, PropertyManager and SimpleItem. Say I have a dtml method at http://myzopeinstance.com/testdtml with contents <dtml-let myvar="'hello world'"><dtml-var testproduct></dtml-let> I'd like "myvar" to be available in the__call__ method of testproduct. I don't know how to do that. Here's my testproduct __call__ method: def __call__(self, client=None, REQUEST=None, **kw): foo="1. client:"+str(client)+" " \ +"2. REQUEST:"+str(REQUEST)+" " \ +"3. kw:"+str(kw)+" " \ +"4. getattr(..REQUEST..):"+str(getattr(self, "REQUEST", None))+" " \ +"5. getattr(..client..):"+str(getattr(self, "client", None))+" " \ +"6. getattr(self, myvar...):"+str(getattr(self, "myvar", None))+ " " \ +"7. aq_get(self, myvar...):"+str(aq_get(self, "myvar", None))+ " " return foo >From poking around I was expecting "myvar" to be accessible somewhere from that list either directly or as an attribute of one of the objects, but it's not. Every call (via a web browser) displays None for every line except #4, the getattr(self, "REQUEST", None) statement. Containment acquisition works more or less the way I would expect, i.e. if myvar is a dtml method in the same folder then the text "hello world" shows up on lines 6 and 7. (I don't understand though why the REQUEST object is always None; I thought when a DTML method calls another object the client and REQUEST parameters are passed in.) I'd appreciate it if someone can explain to me how things work and what I'm doing wrong. ____________________________________________________________________________________ Looking for last minute shopping deals?
