[Zope] zope and session

[Chris McDonough]

Enabling sessions on all page accesses is probably ok (although it
will likely slow things down for pages that don't really need a
session to render).  I dont understand the Postgres usage here, but I
probably don't have to. ;-)

The sessioning Transience product has been essentially rewritten to
address the KeyError problem you're seeing.  It's available in Zope
2.6 or the Zope trunk.  It can also replace the existing Transience
product in Zope 2.5 if you'd rather do that.  You can download a
tarball from
http://cvs.zope.org/Products/Transience/Transience.tar.gz?tarball=1.
Back up your database, replace the lib/python/Products/Transience
directory with the contents of the unpacked Transience tarball, and
restart Zope.

Subject: [Zope] zope and session


i'd like to do some brain picking with regards to zope and session

currently, i'm enabling session on all pages by using script python
[1].
it works ok, but is that the right way of doing it?  and  i sometimes
get
keyerror[2]

also, when enabling sessions, can i get to the data stored in
transient object
so that i can, say, see how many people are currently in session, etc,
etc.

what i'm doing now is storing some of this stuff in postgresql, which
is
wrong, i think.

thanks for all input

--[1]script python---
session = context.REQUEST.SESSION
browsermgr = session.getBrowserIdManager()
r=context.REQUEST

if session.getBrowserIdManager().isBrowserIdNew():
  session.set(browsermgr.getBrowserIdName(),browsermgr.getBrowserId())

  r.set(browsermgr.getBrowserIdName(),browsermgr.getBrowserId())
  context.q_add_user_session(context, r)#update postgresql to get
who's in
session
else:
  if _.SecurityGetUser().getUserName() != 'Anonymous User':
    r.set(browsermgr.getBrowserIdName(),browsermgr.getBrowserId())
    context.q_update_user_session(context, r)#update postgresql to get
who's
in session


--keyerror [2]
  (Object: session_data)
KeyError: duplicate key 08694963A0YdxjlmPiI
