This is so users with huge amount of bookmarks do not have to wait a long time to see results.
* Add a bookmark list and list serializer to server-side to be able to handle paging and load more URL
* Use load-more component to load more bookmark items, 20 at a time in user activity
* Change the way current user is loaded for bookmark ember models because it was breaking/losing resolvedTimezone when loading more items
Previously we relied on race conditions to correctly open a draft, so this
broke.
New code is deliberate.
Also corrects missing observers on composer action
Introduce the concept of "high priority notifications" which include PM and bookmark reminder notifications. Now bookmark reminder notifications act in the same way as PM notifications (float to top of recent list, show in the green bubble) and most instances of unread_private_messages in the UI have been replaced with unread_high_priority_notifications.
The user email digest is changed to just have a section about unread high priority notifications, the unread PM section has been removed.
A high_priority boolean column has been added to the Notification table and relevant indices added to account for it.
unread_private_messages has been kept on the User model purely for backwards compat, but now just returns unread_high_priority_notifications count so this may cause some inconsistencies in the UI.
When editing a post we were incorrectly saving a draft prior to user typing
This caused a bloat in the amount of drafts saved per user and inconsistency
around behavior of "escape" button.
It also lead to lots of warnings about draft conflicts when copying stuff
between posts.
The code is improved to use promises more appropriately, however further
changes are needed to clean up internals so methods consistently return
promises.
Too many methods in the controller sometimes return a promise and sometimes
an object. Long term the methods will become async and all of this will be
corrected.
Usage:
```
{{d-button icon="times" label="foo.bar" isLoading=true}}
```
Note that a button loading without an icon will shrink text size to prevent button to jump in size.
A button while loading is disabled.
The streamlength/height code when true would return just after we had inserted the timeline-controls, resulting, on topic-progress event to display an empty timeline-controls when clicked.
I think this code in unecessary and we should only rely on the code in `hideProgress` which will currenly hide the progress is the stream has only one post displayed on desktop (always shown on mobile).
We have no way of detecting if a browser window is behind another window
or off screen on a virtual desktop.
In some cases we may want events to be delivered quicker to the browser.
Specifically a user may still have a window in view but is not interacting.
This gives users 20 minutes of extra "long polling time" prior to shifting
to short polling.
Even though `type` is an alias for `method`, we have custom logic in `/discourse/lib/ajax` that checks only `type`, and ~200 other ajax calls in the codebase already use `type` param.
Previously we would consider a user "present" and "last seen" if the
browser window was visible.
This has many edge cases, you could be considered present and around for
days just by having a window open and no screensaver on.
Instead we now also check that you either clicked, transitioned around app
or scrolled the page in the last minute in combination with window
visibility
This will lead to more reliable notifications via email and reduce load of
message bus for cases where a user walks away from the terminal
