The variant `update_message` events have this extra sender field not
present in normal update_message events; this field has no purpose, so
we remove it.
Apparently, `update_message` events unexpectedly contained what were
intended to be internal data structures about which users were
mentioned in a given message.
The bug has been present and accumulating new data structures for
years.
Fixing this should improve the performance of handling update_message
events as well as cleaning up this API's interface.
This was discovered by our automated API documentation schema checking
tooling detecting these unexpected elements in these event
definitions; that same logic should prevent future bugs like this from
being introduced in the future.
The parameter Stream.date_created is now sent down to the clients
for both:
- client.get_streams()
- client.list_subscriptions()
API docs updated for stream and subscriptions.
Fixes#15410
We also have the caller pass in the property name for an
additional sanity check.
Note that we don't yet handle the possibility of extra_data;
that will be a subsequent commit.
Also, the stream_id fields aren't in Realm.property_types,
so we specify their types in the checker.
This a pretty big commit, but I really wanted it
to be atomic.
All realm_user/update events look the same from
the top:
_check_realm_user_update = check_events_dict(
required_keys=[
("type", equals("realm_user")),
("op", equals("update")),
("person", _check_realm_user_person),
]
)
And then we have a bunch of fields for person that
are optional, and we usually only send user_id plus
one other field, with the exception of avatar-related
events:
_check_realm_user_person = check_dict_only(
required_keys=[
# vertical formatting
("user_id", check_int),
],
optional_keys=[
("avatar_source", check_string),
("avatar_url", check_none_or(check_string)),
("avatar_url_medium", check_none_or(check_string)),
("avatar_version", check_int),
("bot_owner_id", check_int),
("custom_profile_field", _check_custom_profile_field),
("delivery_email", check_string),
("full_name", check_string),
("role", check_int_in(UserProfile.ROLE_TYPES)),
("email", check_string),
("user_id", check_int),
("timezone", check_string),
],
)
I would start the code review by just skimming the changes
to event_schema.py, to get the big picture of the complexity
here. Basically the schema is just the combined superset of
all the individual schemas that we remove from test_events.
Then I would read test_events.py.
The simplest diffs are basically of this form:
- schema_checker = check_events_dict([
- ('type', equals('realm_user')),
- ('op', equals('update')),
- ('person', check_dict_only([
- ('role', check_int_in(UserProfile.ROLE_TYPES)),
- ('user_id', check_int),
- ])),
- ])
# ...
- schema_checker('events[0]', events[0])
+ check_realm_user_update('events[0]', events[0], {'role'})
Instead of a custom schema checker, we use the "superset"
schema checker, but then we pass in the set of fields that we
expect to be there. Note that 'user_id' is always there.
So most of the heavy lifting happens in this new function
in event_schema.py:
def check_realm_user_update(
var_name: str, event: Dict[str, Any], optional_fields: Set[str],
) -> None:
_check_realm_user_update(var_name, event)
keys = set(event["person"].keys()) - {"user_id"}
assert optional_fields == keys
But we still do some more custom checks in test_events.py.
custom profile fields: check keys of custom_profile_field
def test_custom_profile_field_data_events(self) -> None:
+ self.assertEqual(
+ events[0]['person']['custom_profile_field'].keys(),
+ {"id", "value", "rendered_value"}
+ )
+ check_realm_user_update('events[0]', events[0], {"custom_profile_field"})
+ self.assertEqual(
+ events[0]['person']['custom_profile_field'].keys(),
+ {"id", "value"}
+ )
avatar fields: check more specific types, since the superset
schema has check_none_or(check_string)
def test_change_avatar_fields(self) -> None:
+ check_realm_user_update('events[0]', events[0], avatar_fields)
+ assert isinstance(events[0]['person']['avatar_url'], str)
+ assert isinstance(events[0]['person']['avatar_url_medium'], str)
+ check_realm_user_update('events[0]', events[0], avatar_fields)
+ self.assertEqual(events[0]['person']['avatar_url'], None)
+ self.assertEqual(events[0]['person']['avatar_url_medium'], None)
Also note that avatar_fields is a set of four fields that
are set in event_schema.
full name: no extra work!
def test_change_full_name(self) -> None:
- schema_checker('events[0]', events[0])
+ check_realm_user_update('events[0]', events[0], {'full_name'})
test_change_user_delivery_email_email_address_visibilty_admins:
no extra work for delivery_email
check avatar fields more directly
roles (several examples) -- actually check the specific role
def test_change_realm_authentication_methods(self) -> None:
- schema_checker('events[0]', events[0])
+ check_realm_user_update('events[0]', events[0], {'role'})
+ self.assertEqual(events[0]['person']['role'], role)
bot_owner_id: no extra work!
- change_bot_owner_checker_user('events[1]', events[1])
+ check_realm_user_update('events[1]', events[1], {"bot_owner_id"})
- change_bot_owner_checker_user('events[1]', events[1])
+ check_realm_user_update('events[1]', events[1], {"bot_owner_id"})
- change_bot_owner_checker_user('events[1]', events[1])
+ check_realm_user_update('events[1]', events[1], {"bot_owner_id"})
timezone: no extra work!
- timezone_schema_checker('events[1]', events[1])
+ check_realm_user_update('events[1]', events[1], {"email", "timezone"})
Obviously, this file will soon grow--this
was the easiest way to start without introducing
noise into other commits.
It will soon be structurally similar
to frontend_tests/node_tests/lib/events.js--I
have some ideas there. But this should also
help for things like API docs.
