* Summary: fix slowness due to layout thrashing when reloading a large set of status updates
in order to limit the maximum size of a status in a list view (e.g. the home timeline), so as to avoid having to scroll all the way through an abnormally large status update (see https://github.com/tootsuite/mastodon/pull/8205), the following steps are taken:
•the element containing the status is rendered in the browser
•its height is calculated, to determine if it exceeds the maximum height threshold.
Unfortunately for performance, these steps are carried out in the componentDidMount(/Update) method, which also performs style modifications on the element. The combination of height request and style modification during javascript evaluation in the browser leads to layout-thrashing, where the elements are repeatedly re-laid-out (see https://developers.google.com/web/fundamentals/performance/rendering/avoid-large-complex-layouts-and-layout-thrashing & https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Performance_best_practices_for_Firefox_fe_engineers).
The solution implemented here is to memoize the collapsed state in Redux the first time the status is seen (e.g. when fetched as part of a small batch, to populate the home timeline) , so that on subsequent re-renders, the value can be queried, rather than recalculated. This strategy is derived from https://github.com/tootsuite/mastodon/pull/4439 & https://github.com/tootsuite/mastodon/pull/4909, and should resolve https://github.com/tootsuite/mastodon/issues/12455.

* remove getSnapshotBeforeUpdate from status
* remove componentWillUnmount from status
* persist last-intersected status update and restore when ScrollableList is restored
e.g. when navigating from home-timeline to a status conversational thread and <Back again
* cache currently-viewing status id to avoid calling redux with identical value
* refactor collapse toggle to pass explicit boolean
* Add follow_request notification type
The notification type already existed in the backend but was never pushed
to the front-end. This also means translation strings were also available
for the backend, from the notification mailer.
Unlike other notification types, these are off by default, to match what
I remember of Gargron's view on the topic: that follow requests should not
clutter notifications and should instead be reviewed at the user's own
leisure in the dedicated column.
Since follow requests have their own column, I've deemed it unnecessary to
add a specific tab for them in the notification quick filter.
* Show follow request link in single-column if there are pending requests, even if account isn't locked
* Push follow requests from notifications to the follow_requests list
* Offer to accept or reject follow request from the notification
* Redesign follow request notification
The arguments were passed to the wrong function… also, there is no
need to have a conditional decrementation: failure to upload means
we marked an upload as pending, in all cases.
* Add backend support for bookmarks
Bookmarks behave like favourites, except they aren't shared with other
users and do not have an associated counter.
* Add spec for bookmark endpoints
* Add front-end support for bookmarks
* Introduce OAuth scopes for bookmarks
* Add bookmarks to archive takeout
* Fix migration
* Coding style fixes
* Fix rebase issue
* Update bookmarked_statuses to latest UI changes
* Update bookmark actions to properly reflect status changes in state
* Add bookmarks item to single-column layout
* Make active bookmarks red
Fetching statuses from all followed accounts at once takes too long
within Postgres. Fetching them one by one and merging in Ruby
could be a lot less resource-intensive
Because the query for dynamically fetching the home timeline is so
heavy, we can no longer offer it when the home timeline is missing
* Add some explanation to the mute modal dialog
* Remove `isSubmitting` from mute modal code, this wasn't used
* Refactor block modal

* Refactor SCSS a bit
* Put mute modal toggle to the same side as in the report dialog for consistency
* Reword mute explanation
* Fix mute explanation styling
* Left-align all text in mute confirmation modal
* Restore hashtag suggestions from local tag history
* Append local hashtag suggestions instead of prepending them
* Do not display inaccurate usage statistics for hashtags not retrieved from API
* Fixup
* Allow selecting menu items with the space bar in status dropdown menus
* Fix modals opened by keyboard navigation being immediately closed
* Fix menu items triggering modal actions
* Add Tab trapping inside dropdown menu
* Give focus back to last focused element when status dropdown menu closes
* Optimize makeGetStatus
Because `ImmutableList.filter` always returns a new object and `createSelector`
memoizes based on object identity, the selector returned by `makeGetStatus`
would *always* execute.
To avoid that, we wrap `getFilters` into a new memoizer that memoizes based on
deep equality, thus returning the same object as long as the filters haven't
changed, allowing the memoization of `makeGetStatus` to work.
Furthermore, we memoize the compiled regexs instead of recomputing them each
time the selector is called.
* Fix memoized result being cleared too often
* Make notifications use memoized getFiltersRegex
In some occasions, such as the browser or a browser extension auto-filling
the existing but disabled/hidden CW field, a CW can be set without the user
knowing.
* Improvements to the single column layout
- Add follows and followers link to the right panel
- Increase margins around separators in right panel
- Add follow requests link with counter when account is locked to right panel
* Redirect from getting started to home when navigation panel is visible
* Add responsive panels to the single-column layout
* Fixes
* Fix not being able to save the preference
* Fix code style issues
* Set max-height on the compose textarea and add a link to relationship manager
* Return Status with raw text in raw_content when deleting a status
* Use raw content if available on delete & redraft
* Rename raw_content to text; do not serialize formatted content when source is requested
* Refactor selectComposeSuggestion so that different paths can be updated
* Add suggestions in CW field
* Add emoji suggestion to poll options
* Attempt to fix CSS
* Hide suggestions by default
They will be enabled if the input has focus
The search API now supports returning more results and pagination,
but until the web UI implements pagination, it makes no sense to
dump so many results at once. This fix restores the behaviour
before the API change
* Backend changes for custom emoji support in poll options
* Serialize poll emojis in REST API
* Render custom emojis in poll options
* Render custom emoji in poll options on public pages
The active filter is stored in the web app's settings, but no save
is explicitly triggered, meaning that it is only saved when a different
setting is changed.
* Process incoming poll tallies update
* Send Update on poll vote
* Do not send Updates for a poll more often than once every 3 minutes
* Include voters in people to notify of results update
* Schedule closing poll worker on poll creation
* Add new notification type for ending polls
* Add front-end support for ended poll notifications
* Fix UpdatePollSerializer
* Fix Updates not being triggered by local votes
* Fix tests failure
* Fix web push notifications for closing polls
* Minor cleanup
* Notify voters of both remote and local polls when those close
* Fix delivery of poll updates to mentioned accounts and voters
