When we introduced unicode support in the regular expressions used in watched words (9a27803) we didn't realize the cost adding the `u` flag would be.
Turns out, it's pretty bad when you have lots of regular expressions to test. A customer had slightly less than 200 watched words, and it would freeze the browser for about 2s on the first check of those regular expressions (roughly 10ms per regular expression).
This commit introduces a new field (`word`) to the serialized watched words which is then converted to a very fast and cheap regular expression on the client-side. We use that regexp to quicly check whether a matcher is even worth trying so that we don't incure the cost of compiling the expensive unicode regexp.
This commit also busts the `WordWatcher` cache since we added a new field to be serialized.
One nice side effect of using `matchAll` instead of a `while / exec` loop is that the likeliness of having a bad regexp matching infinitely is vastly reduced 🙌
Cleaning up these routes because they aren't being used
and they don't have a corresponding controller method.
- `POST /groups(.:format) groups#create`
- `DELETE /groups/:id(.:format) groups#destroy`
- `POST /g(.:format) groups#create`
- `DELETE /g/:id(.:format) groups#destroy`
- `GET /posts(.:format) posts#index`
- `GET /posts/new(.:format) posts#new`
- `GET /posts/:id/edit(.:format) posts#edit`
Improves the layout of most grids in posts, by using `object-fit: cover` for most images. This allows images to better fill up the space, without changing their aspect ratio.
This patch sets some limits on custom fields:
- an entity can’t have more than 100 custom fields defined on it
- a custom field can’t hold a value greater than 10,000,000 characters
The current implementation of custom fields is relatively complex and
does an upsert in SQL at some point, thus preventing to simply add an
`ActiveRecord` validation on the custom field model without having to
rewrite a part of the existing logic.
That’s one of the reasons this patch is implementing validations in the
`HasCustomField` module adding them to the model including the module.
In early 2015, the poll plugin was writing its data to custom fields on
the post containing the poll. It was later changed to have dedicated SQL
tables and the polls were migrated but we forgot to clean the existing
data.
Clicking on TOC heading anchors in a subfolder setup was breaking the current URL for users.
Other than the fix this change introduces the ability to test the subfolder setup in system specs.
1. ember proxy stuff still isn't in a great shape, live-reload doesn't work yet, uploads made w/o subfolder won't work, custom fonts don't work, service worker doesn't work. But otherwise it's fine :P
2. I don't know why `HTTP_IF_MODIFIED_SINCE` can be an empty string. Don't have time to investigate, and fast_blank makes this fix an easy solution ;)
When we get to really big files, it's better to not have thousands
of small chunks, since we don't have a resume functionality if the
upload fails. Better to try upload less chunks even if those chunks
are bigger.
For example, with this change a 20GB file would go from 4000 chunks
of the default 5mb to 1000 chunks of the new 20mb size. Still a lot,
but perhaps more manageable.
This is somewhat experimental -- if we still don't see improvements
we can always change back.

Using the runtime information, we will be able to more efficiently group
the test files across the test processes hence leading to better
utilization of resources.
Why this change?
Currently, we're interpolating within a string to set the class for the
`DButton` component. However, the interpolation and formatting of our
handlebars templates result in unnecessary spaces being added to the
class attribute.
```
<button class="sidebar-section-header sidebar-section-header-collapsable btn-flat
btn
no-text
" aria-controls="sidebar-section-content-categories" aria-expanded="true" title="Toggle section" type="button">
...
</button>
```
This makes the HTML elements for buttons hard to read especially when
we're debugging issues in the console. After this change, this is what
we get:
```
<button class="sidebar-section-header sidebar-section-header-collapsable btn-flat btn no-text" aria-controls="sidebar-section-content-categories" aria-expanded="true" title="Toggle section" type="button">
...
</button>
```
This is actually making things more sluggish than necessary. If any perf issue happen out of this they should be handled in the consequences of the resizing, not the resizing itself.
Currently navigating a long topic and then opening chat would cause the view to be scrolled to the bottom. Using `scrollTop` here ensures we correctly scroll to top.
This had been incorrectly moved into `deactivate` during another change.
* FIX: increases resize observer throttle delay
25ms is not necessary and was sometimes causing jankyness.
* FIX: removes ios momentum fix delay
Instead of a 50ms, simply use next+schedule("afterRender") to attempt to have the shortest delay possible.
* FIX: backdrop event propagation
Prevents backdrop touch to propagate to underlying channel/thread.
* UX: adds is-active class to container of active message
This change allows to keep the background on the active message while the actions menu is displayed.
* FIX: prevents skip-link to be selected on press
* UX: allows to close actions menu instantly
The backdrop should always receive events, we don't need to wait for the menu to be fully displayed.
* UI: adds spacing between last message and composer
* UI: makes backdrop less dark
* FIX: makes events passive on long-press modifier
