* 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.
Andrew Lin (https://github.com/onethreeseven) is thanked for his assistance in root cause analysis and solution brainstorming
* 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
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
* Always use the scrollable class for the ScrollList component
Fixes#9499 as well as empty timelines' scrollbar “blinking”
between loading state and empty state.
* Do not display empty message when the list is known to have more elements
Fixes#9500
* Fix LoadMore usage in account media gallery
(Even though that codepath is probably never actually used…)
* Make account media gallery more consistent with account timeline
Fixes#9498
Display “load more” more consistently, add a loading indicator on first load.
* Fix “load more” button when no data has been fetched
So that opening a profile feels faster. Also, pinned toots are not
shown before other toots have loaded. Also, if no toots are loaded,
added empty message
* Add keyword filtering
GET|POST /api/v1/filters
GET|PUT|DELETE /api/v1/filters/:id
- Irreversible filters can drop toots from home or notifications
- Other filters can hide toots through the client app
- Filters use a phrase valid in particular contexts, expiration
* Make sure expired filters don't get applied client-side
* Add missing API methods
* Remove "regex filter" from column settings
* Add tests
* Add test for FeedManager
* Add CustomFilter test
* Add UI for managing filters
* Add streaming API event to allow syncing filters
* Fix tests
onScrollToBottom was a function to run instead of onScrollToTop and
onScroll when scrolling to the bottom. The behavior to prevent
onScrollToTop was inconvenient because the viewport can be at the bottom
and at the top at the same time if the viewport is larger than the
container.
onScrollToBottom was also called when the button to load more is clicked
on contray to the name suggests, which led notifications and
status_list_container components to mark the scrolled location is not at
the top mistakenly.
onLoadMore is a replacement for onScrollToBottom. It will be called
independently from onScrollToTop and onScroll.
* Fix regeneration marker not being removed after completion
* Return HTTP 206 from /api/v1/timelines/home if regeneration in progress
Prioritize RegenerationWorker by putting it into default queue
* Display loading indicator and poll home timeline while it regenerates
* Add graphic to regeneration message
* Make "not found" indicator consistent with home regeneration
* Fix#2102 - Implement hotkeys
Hotkeys on status list:
- r to reply
- m to mention author
- f to favourite
- b to boost
- enter to open status
- p to open author's profile
- up or k to move up in the list
- down or j to move down in the list
- 1-9 to focus a status in one of the columns
- n to focus the compose textarea
- alt+n to start a brand new toot
- backspace to navigate back
* Add navigational hotkeys
The key g followed by:
- s: start
- h: home
- n: notifications
- l: local timeline
- t: federated timeline
- f: favourites
- u: own profile
- p: pinned toots
- b: blocked users
- m: muted users
* Add hotkey for focusing search, make escape un-focus compose/search
* Fix focusing notifications column, fix hotkeys in compose textarea
* fix(dropdown_menu): Keyboard navigation
* fix(icon_button): Add aria-pressed attribute
* fix(privacy_dropdown): Make accessible
* fix(emoji_picker_dropdown): Make accessible
* fix(icon_button): Support tabIndex
* fix(actions_modal): Remove icon from tab order
* fix(dropdown_menu): Add role=group
* fix(setting_toggle): Toggle via space key
* fix(dropdown_menu): Remove redundant handling of Space key
* fix(emoji_picker_dropdown): Remove redundant Space key handling
* fix(privacy_dropdown): Remove redundant Space key handling
* fix(status): Switch to article and add aria-posinset, aria-setsize
* fix(status_list): Use role=feed and pass more ARIA props to Status
* chore(eslint): jsx-a11y/role-supports-aria-props
* refactor(components/status_list): Avoid quering scrollTop if not necessary
* refactor(components/dropdown_menu): Do not render items if not expanded
* refactor: Cherry-pick react-motion imports
* refactor(compose/privacy_dropdown): Do not render options if not open
* refactor(components/column_collapsable): Do not render children if collapsed
Use ES Class Fields & Static Properties (currently stage 2) for improve class outlook.
Added babel-plugin-transform-class-properties as a Babel plugin.
* Replace browserify with webpack
* Add react-intl-translations-manager
* Do not minify in development, add offline-plugin for ServiceWorker background cache updates
* Adjust tests and dependencies
* Fix production deployments
* Fix tests
* More optimizations
* Improve travis cache for npm stuff
* Re-run travis
* Add back support for custom.scss as before
* Remove offline-plugin and babili
* Fix issue with Immutable.List().unshift(...values) not working as expected
* Make travis load schema instead of running all migrations in sequence
* Fix missing React import in WarningContainer. Optimize rendering performance by using ImmutablePureComponent instead of
React.PureComponent. ImmutablePureComponent uses Immutable.is() to compare props. Replace dynamic callback bindings in
<UI />
* Add react definitions to places that use JSX
* Add Procfile.dev for running rails, webpack and streaming API at the same time
