[Zope-DB] Bug in ZSQL method result caching?
Hi All, I'm seeing a fair few errors as follows using Zope 2.8.4: results = self.aZSQLMethod(p1=value1, p2=value2) File lib/python/Shared/DC/ZRDB/DA.py,line 453, in __call__ result=self._cached_result(DB__, (query, self.max_rows_)) File lib/python/Shared/DC/ZRDB/DA.py,line 375, in _cached_result if int(cache[q][0]) == key: KeyError: (execute dbo.aStoredProcedure 'VALUE1', 'VALUE2'\n, 1000, '\nDBConnId: None') The code in question is this, from DA.py: # Try to fetch from cache if hasattr(self,'_v_cache'): cache=self._v_cache else: cache=self._v_cache={}, Bucket() cache, tcache = cache max_cache=self.max_cache_ now=time() t=now-self.cache_time_ if len(cache) max_cache / 2: keys=tcache.keys() keys.reverse() while keys and (len(keys) max_cache or keys[-1] t): key=keys[-1] q=tcache[key] del tcache[key] if int(cache[q][0]) == key: del cache[q] del keys[-1] The if clause seems a bit dodgy... Is that while loop maybe iterating over a mutable object while deleting stuff from it? I'm only stabbing in the dark here... Does anyone have any better ideas? cheers, Chris -- Simplistix - Content Management, Zope Python Consulting - http://www.simplistix.co.uk ___ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db
[Zope-DB] Partial Data Replication to postgreSQL.
We are considering Plone for CMS/Workflow app. However, some of the data from Zodb would need to be replicated into the existing postgreSQL CRM/SCM system, using triggers or something similar. What would be required to do the job? With regards.Sanjay. ___ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db

Re: [Zope-DB] import mysql

Dunno what you're asking... if you want to import a load of rows into a MySQL table, just use MySQL's native tools. If you want to create a load of Plohn objects from an MySQL dump, then your best bet is to write a migrator that uses a ZSQL method to iterate over a select of the data and create the Plohn objects in python... cheers, Chris -- Simplistix - Content Management, Zope Python Consulting - http://www.simplistix.co.uk ___ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db
