The idea here is: Everytime we get hold of a new version of a post, we
update everything about that post everywhere.
This makes the distincion between different event types unnecessary, as
everythng is just a `StatusChangedEvent`.
The main benefit is that posts should be up-to-date more often, which is
important considering there is now editing and #3413
While helping test an issue with
[Bookwyrm](https://github.com/bookwyrm-social/bookwyrm) I noticed that
the URL formats used by that project aren't checked as possible profile
or post links. They're quite close to a couple of others, so I just
copied close examples and edited a couple of terms.
It's pretty minor, I just used a previous commit as a reference. Let me
know if it needs anything more though. I've only quickly tested it on a
local build with a couple of links against a live Bookwyrm and it picks
them up as expected now.
Previously the notification filter and clear actions were shown as
buttons in the UI, with a preference that determined whether they were
displayed.
Remove this preference, and display them as menu items.
- "Filter notifications" is shown as an icon, if possible
- "Clear notifications" is only ever shown as a menu item, to reduce the
chance the user inadvertently selects it
To ensure that the options menu appears correctly, remove the code that
creates a "fake" action bar, and adjust the layouts so that there are
three toolbars;
- mainToolbar -- displays the icons, and the current "location" (Home,
Notifications, etc)
- topNav -- displays the row of tabs at the top
- bottomNav -- displays the row of tabs at the bottom
Only one of them is set as the support action bar (depending on the
user's preferences). This provides the "show a logo" and "show the
options menu" functionality as standard, without needing to re-implement
as the previous code did.
Update to Kotlin 1.9.0 and migrate to newer language idioms.
- Remove unnecessary @OptIn for features migrated to mainstream
- Use `data object` where appropriate
- Use new enum `entries` property
As tests are run against locale JVM and test does not force
a locale to run, so some tests may fail due to a different result only
due to the locale of the JVM used.
Example here with test `same year formatting` in class
`AbsoluteTimeFormatterTest` line 30 on a French JVM. There may be other
lines to fail with other languages.
Fixes#3859
Introduce Flow<T>.throttleFirst(). In a flow this emits the first value,
and each value afterwards that is > some timeout after the previous
value.
This prevents accidental double-taps on UI elements from generating
multiple-actions.
The previous code used debounce(). That has a similar effect, but with
debounce() the code has to wait until after the timeout period has
elapsed before it can process the action, leading to an unnecessary
UI delay.
With throttleFirst a value is emitted immediately, there's no need
to wait. It's subsequent values that are potentially throttled.
formatNumber() was existing code to show numbers with suffixes like K, M, etc, so re-use that code and delete shortNumber().
Update the tests to (a) test formatNumber(), and (b) be parameterised.
When fetching:
- Maintain a marker with the position of the newest fetched notification
- Use the marker to determine which notifications to fetch
- Fetch notifications with min_id to ensure that none are lost
- Update the marker as necessary
- Perform a one-time immediate fetch of notifications on startup
When creating notifications:
- Identify each notification with tag=${MastodonNotificationId}, id=${account.id}
- Remove activeNotifications field, it's no longer necessary
- Use the tag/id tuple to reliably identify existing notifications and avoid creating duplicates
- Cancelling notifications for an account must iterate over all the notifications, and individually remove the notifications that exist for that account.
- Limit notifications to a maximum of 40 (excluding summary notifications)
- Remove notifications (oldest first) to get under this limit
- Rate limit notification creation to 1 per second, so the OS won't drop them
Adjust the summary notification:
- Ensure the summary notification and the child notifications have the same group key
- Dismiss the summary notification if there is only one child notification
NotificationClearBroadcastReceiver is no longer needed, so remove it, and the need for deletePendingIntent.
Fixes#3625, #3539
This makes the notification view for a follow request contain more info about the new follower, and makes the layout (of their name / username) consistent with other notifications that show names/usernames.
* Show better errors with notification loading fails
The errors are returned as a JSON object, parse it, and show the error
message it contains.
Handle the cases where there might be no error message, or the JSON may be
malformed.
Add tests.

* Move compose.* tests to own namespace
* Ignore "@instance..." part of username when computing status length
In a status with a mention ("@foo@example.org") only the "@foo" part should
be included in the calculated status length. It wasn't, so the app was
prevening people from posting statuses that should have been allowed.
Fix this.
- Lift the length calculation code in to a separate static function (easier
and faster to test)
- Add a `MentionSpan` type, to reuse existing code for detecting mentions
- Fix a bug in `FakeSpannable.getSpans()` (it was returning the outer type,
not the wrapped inner span)
- Add additional fast tests
The tests made sense under the `components.compose.ComposeActivity` package,
so I also created that and moved the existing ComposeActivity tests there.

* Static import assertEquals
* Replace "warn"-filtered posts in timelines and thread view with placeholders
* Adapt hashtag muting interface
* Rework filter UI
* Add icon for account preferences
* Clean up UI
* WIP: Use chips instead of a list. Adjust padding
* Scroll the filter edit activity
Nested scrolling views (e.g., an activity that scrolls with an embedded list
that also scrolls) can be difficult UI.
Since the list of contexts is fixed, replace it with a fixed collection of
switches, so there's no need to scroll the list.
Since the list of actions is only two (warn, hide), and are mutually
exclusive, replace the spinner with two radio buttons.
Use the accent colour and title styles on the different heading titles in
the layout, to match the presentation in Preferences.
Add an explicit "Cancel" button.
The layout is a straightforward LinearLayout, so use that instead of
ConstraintLayout, and remove some unncessary IDs.
Update EditFilterActivity to handle the new layout.
* Cleanup
* Add more information to the filter list view
* First pass on code review comments
* Add view model to filters activity
* Add view model to edit filters activity

* Mark as lateinit to avoid unnecessary null checks
* Format with ktlint, whitespace changes only
* Bare minimum necessary to demonstrate paging in notifications
Create `NotificationsPagingSource`. This uses a new `notifications2()` API
call, which will exist until all the code has been adapted. Instead of
using placeholders,
Create `NotificationsPagingAdapter` (will replace `NotificationsAdapater`)
to consume this data.
Expose the paging source view a new `NotificationsViewModel` `flow`, and
submit new pages to the adapter as they are available in
`NotificationsFragment`.
Comment out any other code in `NotificationsFragment` that deals with
loading data from the network. This will be updated as necessary, either
here, or in the view model.
Lots of functionality is missing, including:
- Different views for different notification types
- Starting at the remembered notification position
- Interacting with notifications
- Adjusting the UI state to match the loading state
These will be added incrementally.
* Migrate StatusNotificationViewHolder impl. to NotificationsPagingAdapter
With this change `NotificationsPagingAdapter` shows notifications about a
status correctly.
- Introduce a `ViewHolder` abstract class that all Notification view holders
derive from. Modify the fallback view holder to use this.
- Implement `StatusNotificationViewHolder`. Much of the code is from the
existing implementation in the `NotificationAdapater`.
- The original code split the code that binds values to views between the
adapter's `bindViewHolder` method and the view holder's methods.
In this code, all of the binding code is in the view holder, in a `bind`
method. This is called by the adapter's `bindViewHolder` method. This keeps
all the binding logic in the view holder, where it belongs.
- The new `StatusNotificationViewHolder` uses view binding to access its views
instead of `findViewById`.
- Logically, information about whether to show sensitive media, or open
content warnings should be part of the `StatusDisplayOptions`. So add those
as fields, and populate them appropriately.
This affects code outside notification handling, which will be adjusted
later.
* Note some TODOs to complete before the PR is finished
* Extract StatusNotificationViewHolder to a new file
* Add TODO for NotificationViewData.Concrete
* Convert the adapter to take NotificationViewData.Concrete

* Add a TODO re pinning
* Re-implement "Show more" / "Show less"
* Delete unused updateStatus() function
* Comment out the scroll listener for the moment
* Re-implement applying filters to notifications
Introduce `NotificationsRepository`, to provide access to the notifications
stream.
When changing the filters the flow is as follows:
- User clicks "Apply" in the fragment.
- Fragment calls `viewModel.accept()` with a `UiAction.ApplyFilter` (new
class).
- View model maintains a private flow of incoming UI actions. The new action
is emitted to that flow.
- In view model, `notificationFilter` waits for `.ApplyFilter` actions, and
ensures the filter is saved, then emits it.
- In view model, `pagingDataFlow` waits for new items from
`notificationsFilter` and fetches the notifications from the repository in
response. The repository provides `Notification`, so the model maps them to
`NotificationViewData.Concrete` for display by the adapter.
- In view model the UI state also waits for new items from
`notificationsFilter` and emits a new `UiState` every time the filter is
changed.
When opening the fragment for the first time:
- All of the above machinery, but `notificationFilter` also fetches the filter
from the active account and emits that first. This triggers the first fetch
and the first update of `uiState`.
Also:
- Add TODOs for functionality that is not implemented yet
- Delete a lot of dead code from NotificationsFragment
* Include important preference values in `uiState`
Listen to the flow of eventHub events, filtered to preference changes that
are relevant to the notification view.
When preferences change (or when the view model starts), fetch the current
values, and include them in `uiState`.
Remove preference handling from `NotificationsFragment`, and just use
the values from `uiState`.
Adjust how the `useAbsoluteTime` preference is handled. The previous code
loaded new content (via a diffutil) in to the adapter, which would trigger
a re-binding of the timestamp.
As the adapter content is immutable, the new code simply triggers a
re-binding of the views that are currently visible on screen.
* Update UI in response to different load states
Notifications can be loaded at the top and bottom of the timeline. Add a
new layout to show the progress of these loads, and any errors that can
occur.
Catch network errors in `NotificationsPagingSource` and convert to
`LoadState.Error`.
Add a header/footer to the notifications list to show the load state.
Collect the load state from the adapter, use this to drive the visibility
of different views.
* Save and restore the last read notification ID
Use this when fetching notifications, to centre the list around the
notification that was last read.
* Call notifyItemRangeChanged with the correct parameters
* Don't try and save list position if there are no items in the list
* Show/hide the "Nothing to see" view appropriately
* Update comments
* Handle the case where the notification key no longer exists
* Re-implement support for showMediaPreview and other settings
* Re-implement "hide FAB when scrolling" preference
* Delete dead code

Now there's no Placeholder, everything is a NotificationViewData.
* Improve how notification pages are loaded if the first notification is missing or filtered
* Re-implement clear notifications, show errors
* s/default/from/
* Add missing headers
* Don't process bookmarking via EventHub
- Initiating a bookmark is triggered by the fragment sending a
StatusUiAction.Bookmark
- View model receives this, makes API call, waits for response, emits either
a success or failure state
- Fragment collects success/failure states, updates the UI accordingly

* Change "Load more" to load oldest statuses first in home timeline
Previous behaviour loaded missing statuses by using "since_id" and "max_id".
This loads the most recent N statuses, looking backwards from "max_id".
Change to load the oldest statuses first, assuming the user is scrolling
up through the timeline and will want to load statuses in reverse
chronological order.
* Scroll to the bottom of new entries added by "Load more"
- Remember the position of the "Load more" placeholder
- Check the position of inserted entries
- If they match, scroll to the bottom
* Change "Load more" to load oldest statuses first in home timeline
Previous behaviour loaded missing statuses by using "since_id" and "max_id".
This loads the most recent N statuses, looking backwards from "max_id".
Change to load the oldest statuses first, assuming the user is scrolling
up through the timeline and will want to load statuses in reverse
chronological order.
* Scroll to the bottom of new entries added by "Load more"
- Remember the position of the "Load more" placeholder
- Check the position of inserted entries
- If they match, scroll to the bottom
* Ensure the user can't have two simultaneous "Load more" coroutines
Having two simultanous coroutines would break the calculation used to figure
out which item in the list to scroll to after a "Load more" in the timeline.
Do this by:
- Creating a TimelineUiState and associated flow that tracks the "Load more"
state
- Updating this in the (Cached|Network)TimelineViewModel
- Listening for changes to it in TimelineFragment, and notifying the adapter
- The adapter will disable any placeholder views while "Load more" is active
* Revert changes that loaded the oldest statuses instead of the newest
* Be more robust about locating the status to scroll to
Weirdness with the PagingData library meant that positionStart could still be
wrong after "Load more" was clicked.
Instead, remember the position of the "Load more" item and the ID of the
status immediately after it.
When new items are added, search for the remembered status at the position of
the "Load more" item. This is quick, testing at most LOAD_AT_ONCE items in
the adapter.
If the remembered status is not visible on screen then scroll to it.
* Lint
* Add a preference to specify the reading order
Default behaviour (oldest first) is for "load more" to load statuses and
stay at the oldest of the new statuses.
Alternative behaviour (if the user is reading from top to bottom) is to
stay at the newest of the new statuses.
* Move ReadingOrder enum construction logic in to the enum
* Jump to top if swipe/refresh while preferring newest-first order
* Show a circular progress spinner during "Load more" operations
Remove a dedicated view, and use an icon on the button instead.
Adjust the placeholder attributes and styles accordingly.
* Remove the "loadMoreActive" property
Complicates the code and doesn't really achieve the desired effect. If the
user wants to tap multiple "Load more" buttons they can.
* Update comments in TimelineFragment
* Respect the user's reading order preference if it changes
* Add developer tools
This is for functionality that makes it easier for developers to interact
with the app, or get it in to a known-state.
These features are for use by users, so are only visible in debug builds.
* Adjust how content is loaded based on preferred reading order
- Add the readingOrder to TimelineViewModel so derived classes can use it.
- Update the homeTimeline API to support the `minId` parameter and update
calls in NetworkTimelineViewModel
In CachedTimelineViewModel:
- Set the bounds of the load to be the status IDs on either side of the
placeholder ID (update TimelineDao with a new query for this)
- Load statuses using either minId or sinceId depending on the reading order
- Is there was no overlap then insert the new placeholder at the start/end
of the list depending on reading order
* Lint
* Rename unused dialog parameter to _
* Update API arguments in tests
* Simplify ReadingOrder preference handling
* Fix bug with Placeholder and the "expanded" property
If a status is a Placeholder the "expanded" propery is used to indicate
whether or not it is loading.
replaceStatusRange() set this property based on the old value, and the user's
alwaysOpenSpoiler preference setting.
This shouldn't have been used if the status is a Placeholder, as it can lead
to incorrect loading states.
Fix this.
While I'm here, introduce an explicit computed property for whether a
TimelineStatusEntity is a placeholder, and use that for code clarity.
* Set the "Load more" button background to transparent
* Fix typo.
* Inline spec, update comment
* Revert 1480c6aa3ac5c0c2d362fb271f47ea2259ab14e2
Turns out the behaviour is not desired.
* Remove unnecessary Log call
* Extract function
* Change default to newest first
* Improve the actual and perceived speed of thread loading
To improve the actual speed, note that if the user has opened a thread from
their home timeline then the initial status is cached in the database. Other
statuses in the same thread may be cached as well.
So try and load the initial status from the database, falling back to the
network if it's not present (e.g., the user has opened a thread from the
local or federated timelines, or a search).
Introduce a new loading state to deal with this case.
In typical cases this allows the UI to display the initial status immediately
with no need to show a progress indicator.
To improve the perceived speed, delay showing the initial loading circular
progress indicators by 500ms. If loading the initial status completes within
that time no spinner is shown and the user will perceive the action as
close-to-immediate
(https://www.nngroup.com/articles/response-times-3-important-limits/).
Additionally, introduce an extra indeterminate progress indicator.
The new indicator is linear, anchored to the bottom of the screen, and shows
progress loading ancestor/descendant statuses. Like the other indicator is
also delayed 500ms from when ancestor/descendant status information is
fetched, and if the fetch completes in that time it will not be shown.
* Mark `getStatus` as suspend so it doesn't run on the main thread
* Save an allocation, use an isDetailed parameter to TimelineStatusWithAccount.toViewData
Rename Status.toViewData's "detailed" parameter to "isDetailed" for
consistency with other uses.
* Ensure suspend functions run to completion when testing
* Delay-load the status from the network even if it's cached
This speeds up the UI while ensuring it will eventually contain accurate data
from the remote.
* Load the network status before updating the list
Avoids excess animations if the network copy has changes
* Fix UI flicker when loading reblogged statuses
