Fix authorization_list iteration crashing every Authorize request - #2087
ExpressPet wants to merge 1 commit into
Conversation
get_authorization_status() iterated authorization_list (a dict, keyed by
an arbitrary id per the config schema) with `for auth_entry in auth_list:`,
which yields the dict's keys (strings), not its entry values. Calling
.get() on that string then raised AttributeError, so every Authorize.req
failed with an OCPP InternalError as soon as authorization_list had any
entries at all -- including id_tags that should have matched an explicit
entry, since the loop crashes on its first iteration regardless of match.
Confirmed live against a real charger (Schneider Electric EVlink Pro AC,
OCPP 1.6J) with:
ocpp:
default_authorization_status: Blocked
authorization_list:
fob_test_01:
id_tag: "044517B2936984"
authorization_status: Accepted
Every Authorize.req errored before the fix, regardless of id_tag. After
iterating auth_list.values() instead: the listed tag authorizes
(Accepted) and four different unrecognized tags are correctly denied
(Blocked), across repeated swipes.

CONF_AUTH_LIST supports both mapping and list configurations without calling

Handle the list-shaped authorization configuration.
The supplied test path sets CONF_AUTH_LIST to a list. In that case, auth_list.values() raises AttributeError for every authorization request. Either migrate all configuration writers to the mapping shape, or support both mappings and lists before iterating.
