I fear this is not implemented...


Because, I wanted to control this behaviour through an
environment variable (and not the configuration file!),
I patched "Zope/App/startup.py":

def _isReadOnly():
    ro= os.environ.get('ZODB_READ_ONLY')
    return ro and int(ro) or 0


def startup():
    ....
    try:
        # Try to use custom storage
        m=imp.find_module('custom_zodb',[getConfiguration().instancehome])
    except:
        # if there is no custom_zodb, use the config file specified databases
        configuration = getConfiguration()
        if _isReadOnly():
            configuration.dbtab.getDatabaseFactory('/').config.storage.config.read_only = True
        

As you can see, it is the storage (and not the database),
that must get the "read-only" declaration.
