We use Python 2.3 in Zope-2.8.0-final/bin. I didn't test with Python 2.4. Pierre

What version of Python? I believe we added cyclic GC support to picklers to address this problem, but that was probably for Python 2.4.

After some investigation I noticed what could be an old memory leak related to the ObjectWriter (cycle with the pickler) in ZODB, as can be seen running this short program: import os, os.path from ZODB import FileStorage, DB import transaction import sys import gc class ZODBStore: def __init__(self, name): self.name = name self.absPathName = os.path.dirname(os.path.abspath(name)) def Connect(self): self.file = FileStorage.FileStorage(self.name) self.db = DB(self.file) self.connection = self.db.open() self.root = self.connection.root() self.transaction = transaction.begin() def Disconnect(self): self.Commit() self.connection.close() self.db.close() self.file.close() def Commit(self): self.transaction.commit() def Abort(self): self.transaction.abort() if __name__ == "__main__": ObjectStore = ZODBStore("test.fs") ObjectStore.Connect() ObjectStore.root['Employees'] = ['Jack', 'Joe', 'Bob'] ObjectStore.Disconnect() gc.enable() gc.set_debug(gc.DEBUG_LEAK) resultFile = open('resultConnectionLeak.txt', 'a+') gc.collect() for x in gc.garbage: msg = '>>>> Garbage ' + str(type(x)) + ' ' + str(x) + '\n ' msg += x.__class__.__name__ + ' at ' + str(hex(id(x))) + '\n' resultFile.write(msg) resultFile.close() I fixed it by adding a close function to the ObjectWriter in serialize.py and calling it explicitly from connection.py (modification found in the CVS). def close(self): self._p.persistent_id = None self._p = None _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
