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.
