Room listed in directory only if Only people who have been invited is unchecked

[pedroGitt]

In the room settings:

1. check List this room in matrix.org's room directory? option
2. check Only people who have been invited option
3. go to directory
4. search for the room name
5. the room is not found

It appears that the fact the room is listed in the room directory depends on if one of the following options:

• Anyone who knows the room's link, apart from guests
• Anyone who knows the room's link, including guests

is checked.

This sounds like synapse trying to stop private rooms from being leaked in the room directory. Unsure whether we should let people (accidentally) publish private rooms in the directory or not. We probably should, but need to be careful that it doesn't leak lots of private rooms in the current DBs... @erikjohnston , any idea if this would pose a problem?

There might be a simple way to solve this as a UI tweak:

Private rooms are of no use in the directory, as one cannot join them without an invitation, cannot request an invitation, or do any other action with them. So the current behaviour of synapse to not list them seems reasonable (to me). To reflect that in the Riot UI room settings, it could look like this:

---

WHO CAN ACCESS THIS ROOM?

• Only people who have been invited
• Anyone who knows the room's link, apart from guests
  • List this room in example.com's room directory?
• Anyone who knows the room's link, including guests
  • List this room in example.com's room directory?

Perhaps if the knocking fearture(matrix-org/matrix-spec-proposals#932) is implenmented, room which can't join directly, is expected bing listed in directory.
