* Overhaul the way model visibility scoping works - Previously post visibility scoping required concrete knowledge of the parent discussion, ie. you needed a Discussion model on which you would call `postsVisibleTo($actor)`. This meant that to fetch posts from different discussions (eg. when listing user posts), it was a convoluted process, ultimately causing #1333. Now posts behave like any other model in terms of visibility scoping, and you simply call `whereVisibleTo($actor)` on a Post query. This scope will automatically apply a WHERE EXISTS clause that scopes the query to only include posts whose discussions are visible too. Thus, fetching posts from multiple discussions can now be done in a single query, simplifying things greatly and fixing #1333. - As such, the ScopePostVisibility event has been removed. Also, the rest of the "Scope" events have been consolidated into a single event, ScopeModelVisibility. This event is called whenever a user must have a certain $ability in order to see a set of discussions. Typically this ability is just "view". But in the case of discussions which have been marked as `is_private`, it is "viewPrivate". And in the case of discussions which have been hidden, it is "hide". etc. The relevant API on AbstractPolicy has been refined, now providing `find`, `findPrivate`, `findEmpty`, and `findWithPermission` methods. This could probably do with further refinement and we can re-address it once we get around to implementing more Extenders. - An additional change is that Discussion::comments() (the relation used to calculate the cached number of replies) now yields "comments that are not private", where before it meant "comments that are visible to Guests". This was flawed because eg. comments in non-public tags are technically not visible to Guests. Consequently, the Approval extension must adopt usage of `is_private`, so that posts which are not approved are not included in the replies count. Fundamentally, `is_private` now indicates that a discussion/ post should be hidden by default and should only be visible if it meets certain criteria. This is in comparison to non-is_private entities, which are visible by default and may be hidden if they don't meet certain criteria. Note that these changes have not been extensively tested, but I have been over the logic multiple times and it seems to check out. * Add event to determine whether a discussion `is_private` See #1153 (comment) * Don't include hidden posts in the comments count * Apply fixes from StyleCI (#1350)
