Hi, i am have a big Problem with CoreSession 0.9 (Zope 2.3.3 Win2000 Server). I have 2 Session Data Mangers (dieter and session_mgr). I i want call the getSessionData() of them both method in 1 Transaction. Via calling foo3 I get the error msgs below. I need to call both Data Mangers in 1 Transaction ! By the way: Zope 2.4.2 hangs for the rest of his live after the 2. calling of foo3 Please Help michael Code: def a(self): """khjkjh""" data = self.dieter.getSessionData() data.set('dfd', 'dsd') return None def b(self): """hjhjh""" data2 = self.session_mgr.getSessionData() return None def foo3(self, REQUEST): """hhjh""" #return "dgffdg" c = self.a() #get_transaction().commit(1) d= self.b() #data = self.session_mgr.getSessionData() return "huhuh" First Call Error Type: error Error Value: release unlocked lock Traceback (innermost last): File E:\Beehive\TeDeLine\lib\python\ZPublisher\Publish.py, line 223, in publish_module File E:\Beehive\TeDeLine\lib\python\ZPublisher\Publish.py, line 187, in publish File E:\Beehive\TeDeLine\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File E:\Beehive\TeDeLine\lib\python\ZPublisher\Publish.py, line 175, in publish File E:\Beehive\TeDeLine\lib\python\Zope\__init__.py, line 235, in commit File E:\Beehive\TeDeLine\lib\python\ZODB\Transaction.py, line 335, in commit File E:\Beehive\TeDeLine\lib\python\ZODB\Connection.py, line 657, in tpc_finish File E:\Beehive\TeDeLine\lib\python\ZODB\BaseStorage.py, line 219, in tpc_finish (Object: SessionStorage) error: (see above) Second Call: Error Type: TransactionErrorError Value: A serious error, which was probably a system error, occurred in a previous database transaction.

Hi Michael, Can you do the following? Turn on Zope event logging by using the STUPID_LOG_FILE environment variable (this is documented in LOGGING.txt inside the doc directory, I believe). Log the events to a file named "debug.log". Set another environment variable: CST_DEBUG=1 Then restart Zope. One way to do this in one fell swoop is to do: ./start STUPID_LOG_FILE=debug.log CST_DEBUG=1 Check the debug.log file to make sure things are getting in to it. You'll see Zope startup messages, likely. Then cause the error to occur by calling your external method and send me the log file in email along with any other details you might be able to provide. Many thanks! - C michael kobald wrote:

There is no problem to reference to session data managers. I have two called userSession and siteSession and I set them one after another: <dtml-var "REQUEST.set('uData', userSession.getSessionData())"> <dtml-var "REQUEST.set('sData', siteSession.getSessionData())"> However, I kinda find this funcitonality a bit useless since the two objects are not all that independent. All it allows (since you are not allowed yet to have two session_id_mgr) is to set different varialbes with different timeout values. Can be usefull, but not truly persistant where you want it to be. For instance, a simple session cookie that has only the userid would be nice to keep forever, whereas the rest of the session data expires with the browser session. Not currently possible. Don't know if this helps....

This is unrelated to Michael's original problem, but...
However, I kinda find this funcitonality a bit useless since the two objects are not all that independent. All it allows (since you are not allowed yet to have two session_id_mgr) is to set different varialbes with different timeout values. Can be usefull, but not truly persistant where you want it to be. For instance, a simple session cookie that has only the userid would be nice to keep forever, whereas the rest of the session data expires with the browser session. Not currently possible.
Actually this is incorrect. First of all, you can have several session_id_mgrs. Tey're a bit tricky to install because you can't add a sessionidmgr in a place where another sessionidmgr can be acquired. This is explained in the docs. A common setup would be to have two folders, A and B and to create A.session_id_mgr and B.session_id_mgr. Second of all, different data managers can point at different data containers. And data containers can have different timeouts like you said. And if you put a data container in your "main" ZODB ( or at least in some non-RAM-backed storage), and set its timeout to "0", things that are put into it will never expire. This is what you seem to want. This is also explained further in the docs. Cheers, - C
