As it stands we load up user records quite frequently on the topic pages,
this in turn pulls all the columns for the users being selected, just to
discard them after they are loaded
New structure keeps all options in a discrete table, this is better organised
and allows us to easily add more column without worrying about bloating the
user table
UX: improve messaging so notifications list is far more stable
PERF: improve performance of notifcation lookup queries
- Add feature "SetTransientHeader" that allows shipping info to server
in the next Ajax request
- remove local storage hack used for notifications
- amend lookupStale to return hydrated objects, move logic into store
- stop magically clearing various notifications (likes, invitee accepted, group_summary, granted badge)
Messages are now in 3 buckets
- Inbox for all new messages
- Sent for all sent messages
- Archive for all messages you are done with
You can select messages from your Inbox or Sent and move them to your Archive,
you can move messages out of your Archive similarly
Similar concept applied to group messages, except that archiving and unarchiving
will apply to all group members
Re-organise user page so it is easier to find interesting info
split it into tabs
- Introduce notifications and messages tabs
- Stop couting stuff for the user page to speed up rendering
- Suppress more information when viewing your own profile
Group owners are regular users that can add or remove users to a group
The Admin UX allows admins to appoint group owners
The public group UX will display group owners first and unlock UI to
add and remove members
Group owners can only be appointed on non automatic groups
Group owners may not appoint another group owner
On sites that don't otherwise configure an avatar fallback, Discourse will
now tell the client to get its letter avatars from a location which nginx
proxies to the centralised `avatars.discourse.org` service. This alleviates
privacy concerns, whilst still providing some degree of performance benefit
(no need for every site to delay avatar response by 300ms for image
rendering).
It is still possible to gain the benefits of global image caching and the
lower latency of requesting directly from a CDN, by explicitly changing the
`external_system_avatars_url` site setting to
`https://avatars.discourse.org/letter/{first_letter}/{color}/{size}.png`.
We cap new and unread at 2/5th of SiteSetting.max_tracked_new_unread
This dynamic capping is applied under 2 conditions:
1. New capping is applied once every 15 minutes in the periodical job, this effectively ensures that usually even super active sites are capped at 200 new items
2. Unread capping is applied if a user hits max_tracked_new_unread,
meaning if new + unread == 500, we defer a job that runs within 15 minutes that will cap user at 200 unread
This logic ensures that at worst case a user gets "bad" numbers for 15 minutes and then the system goes ahead and fixes itself up
