Allow for a default translation string to be returned when a translation cannot
be found.
Useful in contexts where there is a known fallback, such as custom emoji group
strings.
This commit removes many uses of `this._$textarea`, and also switches us to use `document.execCommand("insertText")` for the majority of manipulations. This means that the browser undo history will be preserved when doing things like pasting rich html, using bold/italic shortcuts, etc.
These manipulations are already extensively tested. This commit extends a few of the tests to verify the undo behavior.
There are still a few cases (e.g. replacing upload placeholders with true URLs) where we don't necessarily want to bring the composer into focus. In those cases, the old history-breaking behavior remains for now.
The test was un-skipped in 6f25f1736031184ac05fc4059edde772a7e3bf56 but
has since been flaky again. Removing the test completely as it has
resulted in more pain for us than the value the test provides.
This commit introduces a new site setting: `block_hotlinked_media`. When enabled, all attempts to hotlink media (images, videos, and audio) will fail, and be replaced with a linked placeholder. Exceptions to the rule can be added via `block_hotlinked_media_exceptions`.
`download_remote_image_to_local` can be used alongside this feature. In that case, hotlinked images will be blocked immediately when the post is created, but will then be replaced with the downloaded version a few seconds later.
This implementation is purely server-side, and does not impact the composer preview.
Technically, there are two stages to this feature:
1. `PrettyText.sanitize_hotlinked_media` is called during `PrettyText.cook`, and whenever new images are introduced by Onebox. It will iterate over all src/srcset attributes in the post HTML and check if they're allowed. If not, the attributes will be removed and replaced with a `data-blocked-hotlinked-src(set)` attribute
2. In the `CookedPostProcessor`, we iterate over all `data-blocked-hotlinked-src(set)` attributes and check whether we have a downloaded version of the media. If yes, we update the src to use the downloaded version. If not, the entire media element is replaced with a placeholder. The placeholder is labelled 'external media', and is a link to the offsite media.
If the select-kit header is not in the viewport (scrolled out of view), popper adds a data-popper-reference-hidden attribute.
This PR adds the recommended styles to "hide" the select-kit body when that happens. See
https://popper.js.org/docs/v2/modifiers/hide/
Twitter does not allow SVGs to be used for twitter:image
metadata (see https://developer.twitter.com/en/docs/twitter-for-websites/cards/overview/markup)
so we should fall back to the site logo if the image option
provided to `crawlable_meta_data` or SiteSetting.site_twitter_summary_large_image_url
is an SVG, and do not add the meta tag for twitter:image at all
if the site logo is an SVG.

This commit seeks to only handle the `f=tracked` and `filter=tracked`
query params for a topic list. There are other "hidden" filters for a
topic list which can be activated by passing the right query param to
the request. However, they are hidden because there is no way to
activate those filters via the UI. We are handling the `f=tracked`
filter because we will soon be adding a link that allows a user to
quickly view their tracked topics.
Due to some changes we started notifying via push notifications on other
families of notifications. There are a total of about 30 or so possible
notification you could get, some can be pushed.
This fallback means that if for any reason we are unable to find an icon
for a push notification we just fallback to the Discourse logo.
Also go with a simple reply icon for watching first post.
Note, that in production `image_url` can return an exception if an image is
missing. This is not the case in test / development.
