My problems on this subject didn't get resolved since my last post, but
I have some new info and questions -
The sympthoms (Zope 3.1.0c1):
Database adapters are not usable by principals other than the
zope.Manager, in the principals.zcml file. Any other principal is
unauthenticated - I tried principals.zcml regular user with
zope.ManageContent, zope.UseDatabaseConnections and zope.View granted,
pluggable authentication user with the zope.Manager role granted, and
finally - principals.zcml regular user with zope.Manager role.
All principals are able to see and manage the connection object, but
can't retrieve results. This is tested and true for both psycopg and
Gadfly database adapters.
This is the exception I get when trying to use SQL script:
* Module zope.app.sqlscript.browser.sqlscript, line 39, in
for argname, argvalue in self.context.getArguments().items():
Unauthorized: (<zope.app.sqlscript.sqlscript.Arguments object at
0xa03e86c>, 'items', 'zope.ManageContent')
This is the excpetion from the test page of the connection object (in
/++etc++site/tools) when I use principal with zope.Manager granted:
* Module zope.app.rdb, line 372, in queryForResults
cursor = conn.cursor()
Unauthorized: (<zope.app.rdb.ZopeConnection object at 0xad11c2c>,
Hmm... Database adapter working just fine for me.
Looking at the code, the ZopeConnection object is created by the
ZopeDatabaseAdapter class in zope.app.rdb (inherited by the actual
DatabaseAdapter) with a simple call -
self._v_connection = ZopeConnection(self._connection_factory(), self)
and the ZopeConnection class does not have anything, that deals with
security, as far as I can see.
See zope/app/rdb/configure.zcml for security declarations.
My question is, does this eventually mean, that ZopeConnection objects,
which are created at run-time, are not security proxied and consequently
unauthorized in all cases (except the system_user) and if yes, what
should be done? I'm not familiar with the Zope3 environment and I don't
know how and where objects get proxied.
Or is there something I'm missing here ?
Can you repeat all this experiments on clean Z3 setup (without any additional
components and without your old Data.fs file, check also for all possibly
conflicting modules on the PYTHONPATH)?
