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).
For example given a custom badge with SQL:
```
SELECT 1
-- I am a comment
```
You end up with
```
FROM (SELECT 1
-- I am a comment) q
```
This fix adds newlines so you end up with the now-valid:
```
FROM (
SELECT 1
-- I am a comment
) q
```
This adds rubocop-rspec, and enables some cops that were either already passing or are passing now, after fixing them in this commit.
Some new cops are disabled for now, with annotation: "TODO" or "To be decided". Those either need to be discussed first, or require manual changes, or the number of found and fixed offenses is too large to bundle them up in a single PR.
Includes:
* DEV: Update rubocop's `TargetRubyVersion` to 2.6
* DEV: Enable RSpec/VoidExpect
* DEV: Enable RSpec/SharedContext
* DEV: Enable RSpec/EmptyExampleGroup (Removed an obsolete empty spec file)
* DEV: Enable RSpec/ItBehavesLike
* DEV: Remove RSpec/ScatteredLet (It's too strict, as it doesn't recognize fab! as a let-like)
* DEV: Remove RSpec/MultipleExpectations
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.
