Thanks Dieter, it's work.
But i have a problem with this:
When I ran the test python script (see below) in Zope or I called the
url directly from the browser , I got an error:
Error Type: KeyError
Error Value: 'SESSION'
# Python test script ###
from Products.PythonScripts.standard import html_quote
request = context.REQUEST
RESPONSE = request.RESPONSE
session = request.SESSION
session.set('VAR',99)
This is the simple external event handler script
external module to catch session changes
###
def onSessionStart(item, container):
from logging import getLogger
request = container.REQUEST
user = request.AUTHENTICATED_USER.getUserName()
LOG = getLogger('DEMO')
session = request.SESSION
LOG.info( Item data: %s % item )
LOG.info( Request data: %s % request )
LOG.info( Session data: %s % session )
And in the event.log I can see this error:
# event.log ###

The Transient Object Container (that's the session container) has too
scripts for this. You configure them in Zope's configuration file.

[Zope] How can I store session data to db on login/logoff events ?
Hi All!
Sorry for my stupid question and my english:
I would like store some session data to db when the users log into my
zope system and when the session object will be deleted.
When the users log into the system the index_html script sets some data
to request.SESSION object.
I have a script called addScript that runs when an object is added to
transient data container.
In the addScript I try receive data with yyy =
container.SESSION.get('xxx') or item.get() but I cannot see the
keys.
How can I retrieve the user SESSION data when the items are created or
deleted from the transient object container?
Thank you in advance
Antal

RE: [Zope] Problem with running same script at a time
Thank you Dieter! Here is the exact scenario, which in I first observed the problem: I have a external zope python module that communicates via TCP with a background system written in Java. I have a background system that communicates with the Zope via URL. I have a demo user folder in my Zope project with two scripts. The first script sends a tcp message to the background (with the help of external module), the second one do something when the background call it via url. First the Zope script sends a tcp message to background system, and waits for the reply. The background receives the message and try to call the url by http request, then if it is success replies to Zope script's tcp request. Here is the problem. The background system cannot access the URL until in the first script tcp timeout happen. When I move the second script into other outer folder, all is OK. It is very strange, and I'v never read from this problem before.

I use the same product. This problem is one of the others... I had to fix a problem in psycopg: During connect, Python's Global Interpreter Lock (GIL) was not released (freezing Zope during connect). Usually, this is not a problem as connect is quite a fast operation. We noticed it only when the server for the postgres installation was down (then connect became a several minute operation until the TCP timeout happened). However, it is unlikely, that this is your problem. The behaviour is the same when i use long socket communication (as a tcp client), etc. This, too, should not happen -- and I never observed it (but a colleague reported something like this but never showed it to me -- and I did not believe him; or more precisly, I tested his alledgedly observed behaviour and could not reproduce it...) In these cases the folder wich contains the scripts be unaccessible. Unbelievable -- unless your folder access triggers the long socket communication. In this case, it would not be the old socket communication that blocks but the new one. Of course, your folder access should not trigger anything else... -- 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 )
RE: [Zope] Problem with running same script at a time
Thank you Dieter, I will try it. -Original Message- From: Dieter Maurer [mailto:[EMAIL PROTECTED] Sent: Friday, September 22, 2006 8:03 PM To: Pletli Antal Cc: zope@zope.org Subject: RE: [Zope] Problem with running same script at a time Pletli Antal wrote at 2006-9-22 08:51 +0200: ... I have a demo user folder in my Zope project with two scripts. The first script sends a tcp message to the background (with the help of external module), the second one do something when the background call it via url. The problem is your setup. I have to explain a bit that you can understand the problem. Zope's request processing has roughly two phases: URL traversal to locate the object identified by the URL and then calling the located object. At the end of URL traversal lies the user authentication. This proceeds as follows: Zope starts at the located object and looks upward (towards to root) to find a User Folder which is ready to authenticate the user with the required roles. It will ask each User Folder it finds above the object until one gives a positive answer. The highest user folder will always return a user, maybe the anonymous one. If your User Folder calls out to a backend system and this backend system calls back (via URL) into an area controlled by your User Folder, then you lose -- as the User Folder will again call out and wait for an answer before it will call the object... Move the thing called back out of your hiararchy dominated by the UserFolder. Then, you might have success. -- 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 )
RE: [Zope] Problem with running same script at a time
Hi Dieter! Than you for your answer! I use the same product. This problem is one of the others... The behaviour is the same when i use long socket communication (as a tcp client), etc. In these cases the folder wich contains the scripts be unaccessible. Maybe have i a wrong zope configuration (i use default config)?

RE: [Zope] Problem with running same script at a time
My system is a developer server so i'm the only one who use the zope. When i run the script there is not other worker script. I'm newbie but i read that there is a tool named zasync that maybe solves my problem but i cannot install it yet. I would like solve my problem without this if possible.
