  • [x] TinodeWeb/tinodejs: javascript client
  • Version of the client 0.16.3

Steps to reproduce

Developing search plugin. Regarding this doc: https://gowalker.org/github.com/tinode/chat/pbx#PluginClient Find should return type SearchFound whitch should contain type TopicSub list in result. For TopicSub we can set AccessMode (https://gowalker.org/github.com/tinode/chat/pbx#AccessMode) that have want and given properties. Fragments for search plugin python code

class Plugin(pbx.PluginServicer):
    def Find(
            context  # type: grpc.RpcContext
        sf = pb.SearchFound()

        query = event.query

        cursor = get_cursor()
        term = '%' + query + '%'

        user_id = event.user_id[3:]
        user_id_int = decode_uid(user_id)

        cursor.execute(SEARCH_QUERY, (term, user_id_int))

        for row in cursor.fetchall():
            ts = pb.TopicSub()
            ts.user_id = encode_uid(row['id'])
            ts.public = row['public']

            access = json.loads(row['access'])

            ts.acs.given = access['Auth'].encode('utf-8')
            ts.acs.want = access['Anon'].encode('utf-8')

            ts.updated_at = int(row['updatedat'].strftime('%s')) * 1000


        sf.status = pb.RespCode.RESPOND

        return sf

And now we go to server code Method pluginFind passes response to pbSubSliceDeserialize from pbconverter.go (https://github.com/tinode/chat/blob/8d77b2be39a24e85f125e09e247ab17437df7878/server/pbconverter.go#L832) Server sets ModeGiven and ModeWant. After that here in topic.go (https://github.com/tinode/chat/blob/8d77b2be39a24e85f125e09e247ab17437df7878/server/topic.go#L1828) server is trying to read default access if topic category is find. So there is no way to set acs for search results from plugin.

Expected behaviour

There should be ability to set ACS for search results from plugin.

Actual behaviour

There is no way to set ACS for search results from plugin.

    The problem is that default search returns list of subscriptions with ACS mode from user config (in my case JRWPA)

    {"meta":{"id":"123237","topic":"fnd","ts":"2020-03-12T17:12:48.159Z","sub":[{"updated":"2020-03-11T16:45:00.401Z","acs":{"mode":"JRWPA"},"public":{"fn":"Generated test"},"private":["test"],"user":"usr0R4O4rKOL0c"}]}}

    And there is no possibility to set any ACS mode from search plugin. So it will always show N.

    OK, I see your point. That's indeed an oversight. I'll try to fix it in the next release.

    It's been released as 0.16.4. Do you have further questions?

    Actually it is not a bug. Maybe it's a logical problem or some misunderstanding.

    What exactly do you expect to see in ModeGiven and ModeWant? These values are present only for existing subscriptions. I.e. if Bob and Alice have a p2p topic, then ModeWant and ModeGiven are defined for them. Otherwise they are undefined. 'Find' assumes that you are searching for new contacts, consequently, these contacts generally don't have a p2p topic with the current user (other than by chance) and it does not return ModeGiven/ModeWant because they are usually N.

    defacs on the other hand are useful. They tell you what kind of connection you can create with the new user/topic.
