This might be an FAQ but I wasn't able to find it when searching.
How do I get access to the value of 'session-timeout-minutes' coming
from etc/zope.conf in runtime Zope?
My app knows when people log in. I want the app to say "You'll be
securely logged in for another 25 minutes unless you log out or log in
again".

The trail to figure this out:

- ZCML directives for zope.conf are defined in
Zope2/Startup/zopeschema.xml. It defines a 'session_timeout_minutes'
handler.

- Handlers are defined in Zope2/Startup/handlers.py;
session_timeout_minutes sets the defined value as a environment
variable: ZSESSIN_TIMEUT_MINS

Presumably you can read out this var from os.environ for your own
purposes; note however that I have found no mention of the ZSESSIN_
variables outside of handlers.py, they appear to be otherwise unused.

Great. I'll try that.
Thanks!

To get number of zope threads from zope.conf I used this code:

from App.config import getConfiguration
conf = getConfiguration()
print conf.zserver_threads

Possibly you'll find session-timeout-minutes there too.

BTW. AFAIR session timeout is not a precise value especially
if you're using high value for session-resolution-seconds

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.

This means, there is some way to access it. You can use this
way in your own application (you might need a proxy role to
get sufficient privileges).

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

In your code, you can use something like :
<tal code>
you'll be
securely logged in for another <span tal:replace="python
() "></span>
minutes unless you log out or log in
again".
</tal>

Thanks but I solved it using::

from App.config import getConfiguration
conf = getConfiguration()
setattr(MyProductClass, 'SESSIN_TIMEUT_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(, None)
if ts is None:
return 0
minutes = self.SESSIN_TIMEUT_MINUTES - (time.time() - ts) / 60
return int(minutes)
