You can easily achieve almost sure conflicts. We did once with a frame based solution: All frames in a frameset accessed the session and tried to store some information in it. As the browser requested the frames concurrently, there was a very high probablity for conflicts. In our case, there was no real need for most of the frames to access the session. Removing the unnecessary accesses removed the problem. But, if the frames had a real need to store something in the session, we would have to use persistent subobjects in the session to separate the access of the various frames into different objects. >If I do not use the session object in my code, I have no errors at all >and everything just goes fine. Then, you are using some add-on component that *is* using the session object. If the session is not used, there will be no session related conflict error. >Any idea on how to debug this ?

You could try to delete "/temp_folder/session_data" temporarily (it will be recreated on the next Zope startup) to find out which component does use sessions. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] zope, webdav, ical, vcalendar, etc.
I am trying to dynamically create iCalendar or vCalendar files. I can do this with a Zope Page Template, naming it myCalendar.ics. When myCalendar.ics is accessed through a web browser, iCal pops up and asks what I want to do with the calendar info, etc. and all is well. But what I would like to do is use iCal or thunderbird( lightening ) to subscribe to the calendar so that updates are handled automatically. For iCal to do this, it wants to access the ics file via webdav. So I attempt to connect to zope via its webdav port and request the sale zpt, but of course it sends it as its source, not as the rendered calendar. If i take out all the TAL and just have a static vCalendar or iCalendar file then this works via webdav but my whole reason for doing this is so that I can populate the calendar with events form a RDBMS when the myCalendar.ics template is called. Your ideas appreciated. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Technically no but it is really strange and I believe bad (if not impossible) way to distribute application among dev, test, production environments... For me there should of course be another developement Zope instance (and test instance and more), but application should be moved between instances by 'copying' changed Products or exporting changed files/folders from ZODB (.zexp files), or something like that.

I added a new faster session object in my root folder. Once it was created, i was on the property manager form and clicked on the test tab and got the error reported above. Is the request["SESSION"] object that you use in your code addressing the classic SESSION object (in temp_folder/session_data_container) or does it address your new session data objects ? for the latter case, maybe i should rename the classic (zope's) SESSION object to SESSION2 or something...

[Zope] Florent Guillaume's database Conflict Error on session objects patch not working ?
Hi all, As discussed here : http://mail.zope.org/pipermail/zope/2007-January/170151.html and continued here : http://mail.zope.org/pipermail/zope/2007-January/170156.html I am experiencing issues regarding a database ConflictError on session objects. I use zope 2.9.0 python 2.4.2, and the code of the MultiDB support has been patched (as suggested by Florent Guillaume) http://mail.zope.org/pipermail/zodb-dev/2006-January/009737.html My main concern is to debug my application where, on every couple of requests coming from two different browsers at the same time (before the first request is , one of them wins and the other always fails and raises a conflict error. It is not a ReadConflictError, nor a WriteConflictError. It is a "ConflictError: database conflict error". I am aware that conflicts occure up to 20% of the time, but in my case it is almost 100% in this specific situation ! If I do not use the session object in my code, I have no errors at all and everything just goes fine. Any idea on how to debug this ? Florent, maybe ? someone help me ! I am stuck on this for 2 weeks now. NOTE : I do not use Zeo, nor frames.

Re: [Zope] session-timeout-minutes value in runtime Zope
Thanks but I solved it using:: from App.config import getConfiguration conf = getConfiguration() setattr(MyProductClass, 'SESSION_TIMEOUT_MINUTES', conf.session_timeout_minutes) Now I can use this:: class MyProductClass: def getLoggedInSecurelyMinutesLeft(self): """ return how many minutes there is left on the securely logged in session. """ ts = self.get_session(SESSIONKEY_USER_SECURE_TIMESTAMP, None) if ts is None: return 0 minutes = self.SESSION_TIMEOUT_MINUTES - (time.time() - ts) / 60 return int(minutes) yacine chaouche wrote: I don't know if this is what you want.

The value is used to configure the so called "Session Data Manager" (usually "/temp_folder/session_data"). Its management page is able to show you the value.

Hi All, Could anyone advise whether this has been fixed in any of the Zope versions beyond v2.9.3: To-do: * Add cyclic-garbage collection support to C extension classes, especially to acquisition wrappers.

Re: [Zope] session-timeout-minutes value in runtime Zope
I don't know if this is what you want. If you want to have access, in your code, to the session-timeout-minutes variable, you can try this methode on your session_data_manager object : getTimeoutMinutes(self): Return the number of minutes allowed for subobject inactivity before expiration. PermissionView management screens This is from the api documentation of TransientContainer class, found in the help link in the ZMI of temp_folder/session_data_manager. In your code, you can use something like : you'll be securely logged in for another minutes unless you log out or log in again".
