Previous code assumed the active account could always be determined from
the account manager.
This causes a few problems.
1. The account manager has to handle the case where there is no active
account (e.g., the user is logging out of the last account). This meant
the `activeAccount` property had to be nullable, so every consumer of
that property either used it with a `let` or `!!` expression.
2. The active account can change over the life of the UI component, for
example, when the user is switching accounts. There's a theoretical race
condition where the UI component has started an operation for one
account, then the account changes and the network authentication code
uses the new account.
3. All operations assume they operate on whatever the active account is,
making it difficult to provide any features that allow the user to
temporarily operate as another account ("Boost as...", etc).
This "ambient account" was effectively global mutable state, with all
the problems that can cause.
Start to fix this. The changes in this commit do not fix the problem
completely, but they are some progress.
Each activity (except LoginActivity) is expected to be launched with an
intent that includes the ID of the Pachli account it defaults to
operating with. This is `pachliAccountId`, and is the *database ID*
(not the server ID) of the account. This is non-null, which removes one
class of bugs.
This account is passed to each fragment and any piece of code that has
to perform an operation on behalf of this account. It's not used in
most of those places yet, that will be done over a number of followup
PRs as part of modernising each module.
Previous code didn't encode v2 filter keywords, so created v2 filters by
first creating the filter with no keywords (one API call) then making
1-N API calls to add each keyword to the filter.
Fix this by adding a dedicated converter for the `NewContentFilter` type
that encodes it correctly so the filter can be created with a single API
call.
This necessitates moving some types around,
It's possible for some servers to return a conversation that has an
empty (or possibly missing) `accounts` property. In the previous code
this would crash trying to access an item in an empty list.
Fix this by handling the "no participants" case.
Fixes#971
The new anti-harassment features will add several different types of
filtering options through the UI.
To ensure there is no confusion, rename the existing "Filters" UI and
code to "Content filters" to accurately describe what they operate on,
distinct from new filters which will act on account metadata.
Fixes#926.
Previously, tapping a tab would jump to the top of the loaded content,
which might trigger a load of a fresh page.
Provide a preference to control this; the default is the current
behaviour, the user can also choose to discard the current content and
load the newest content.
Fixes#939
Update `DownloadUrlUseCase` with a parameter to specify the account that
"owns" the media. This is either the account that posted the status, or
the account being viewed (e.g., if downloading an account's header
image).
Add a new `DownloadLocation` enum constant to download to directories
named after that account.
Pass this information through at the call sites.
Fixes#938
Provde an `appTheme` property in `SharedPreferenceRepository` to manage
read access, simplifying calling code.
Update `PreferenceEnum.from` to check the `value` property of the enum
first.
Fixes#950
The existing code downloaded any attachments to the user's "Downloads"
folder. If the user is logged in with several accounts these downloads
will be mixed up together.
Fix this by adding a new preference that allows the user to specify the
downloads should be placed in a sub-folder per account, named after the
account.
To do this:
- Add an interface for enums that can be used as preferences, with
properties for the string resource to display and the value to store.
- Add `EnumListPreference`, a `ListPreference` that allows the user to
choose between different enum values.
- Add a `DownloadLocation` enum and preference key so the user can
choose the location.
- Add a `core.domain` module, with a use case for downloading URLs that
respect's the user's download preference. Use this use-case everywhere
that files are currently downloaded.
Fixes#938
Previous code showed any JSON-wrapped errors from notification fetches
as the JSON string, instead of the error message.
Fix this by switching to `ApiResult` and using the formatted error
message.
Fixes 937
Previous code saved the reading position of a fully visible status. But
there are situations where no status is fully visible.
1. The user is in the middle of viewing a status longer than the screen
height, and the top/bottom of the status are off the top/bottom of the
screen.
2. The user has scrolled between two statuses. Collectively they are
longer than the screen height, and the top of one status is off the top
of the screen and the bottom of the other status is off the bottom of
the screen.
In both cases the user's reading position was not saved.
In these situations use the ID of the status closest to the bottom of
the screen, even if not fully visible. This should ensure the user never
missing anything.
Fixes#936
Previous code used `Response`. Convert to `ApiResult` as part of the
work to implement anti-harassment controls, which will need to query the
user's list of accounts they are following.
Converting just `accountFollowing` wasn't practical, as all the methods
are called by a single function in `AccountListFragment` which expects
the return type to be the same.
In rare occasions the preview card text could overlap the image if the
image had a portrait aspect ratio.
This seems to be due to the use of the `with(...) {}` scope function and
Kotlin's interoperability with Java setters.
Replace this with code that explicitly gets and sets the layout params
to ensure they are set correctly.
androidx.media3 1.4.0-rc01 and above (at the time of writing) has a bug
that breaks shared element transitions with a `PlayerView` (see
https://github.com/androidx/media/issues/1594).
This can be worked around by setting `app:surface_type="texture_view"`.
This uses more power, but for the typical length of social media videos
this shouldn't be a problem at the moment.
Fixes#920.
Previous code used `filterIsInstance<Ok<UploadEvent.FinishedEvent>>()`.
This can fail at runtime with class cast exception because the type in
`Ok<...>` is erased so `filterIsInstance` was accepting any `Ok`
`Result`. Later attempts to operate on it as a `.FinishedEvent`
generated the run time error.
Fix that by explicitly checking the type of the `Ok` result in `first`
instead.
Previous code had a bug/typo, which meant the app the user was posting
from was not shown if the app did not have an associated website. But
the bullet separating the parts of the text was still shown, resulting
in a spurious dangling bullet.
Previous code didn't set the textDirection for the status content, so
the first para of RTL text might be rendered incorrectly.
In addition, mentions and tags weren't BIDI wrapped, so would appear as
"foo@" and "foo#" in RTL statuses, instead of "@foo" and "#foo".
Fix both of these issues.
Fixes#870
Two problems with the previous code when search filters were visible:
1. The link icon overrode the tint, so didn't appear correctly in dark
and black mode.
2. The horizontal scroll view had the wrong background colour in black
mode.
Fix both, by updating the icon and adding a new style for the scroll
view.
While I'm here remove an obsolete comment and tighten up visibility.
Fixes#875
Clean up the notification handling code and fix a lot of bugs, hopefully
without introducing new ones in the process.
Specific bugs discovered and fixed:
- The code that tried to sync notification filtering state between the
server and Pachli could fail, leaving things in an inconsistent state,
resulting in dropped notifications. Remove that code, do filtering
client-side.
- Logging out of an account would disable push notifications for all
accounts.
- If any account did not support push notifications then push
notifications were disabled for all accounts.
- If any account did not support push notifications the user was
prompted to log out of all accounts. Drop that entirely.
- The UnifiedPush library could get to a state where configuring the
notification mechanism would silently fail,
The preferences UI now has a section for notifications, showing:
- The Unified Push distributor in use (if any)
- A mechanism to change the distributor
- Per-account configuration and notification fetch details
- Battery optimisation state
General changes:
- Update to UnifiedPush library 2.4.0.
- NotificationFetcher.fetchAndShow() can now fetch a single account's
notifications, or all accounts, depending on data passed to the worker.
- Use ApiResult for `push/subscription` responses.
- Drop the "needs migration" terminology for the more specific "has push
scope", to make it clear what the issue with the account is.
Add a new set of preferences, "Lab experiments", to control features
that are under investigation and may never make it into the mainstream.
Add the first experimental feature, which reverses the order of the home
timeline, so posts are shown oldest first instead of newest first.
Byline changes inadvertently changed how the preview image is laid out,
breaking the "Image at start, info at end" variant.
Previous code did not always show the card description if the text was
present, fix that.
Previous code set a min-height, which is no longer necessary after the
other layout changes. But it meant that a preview card with a one-line
title, no synopsis, and a URL, was taking up too much vertical space.
Previous code displayed a large placeholder icon if there was no preview
image for a preview card.
This reduces the amount of space available for the actual preview text
(i.e., title and description) and did not convey additional information
in the limited space available on the timeline.
So remove it.
While I'm here simplify the PreviewCard layout and migrate to
ConstraintLayout.
The `canFilter()` implementation could crash if `server` (marked
`lateinit`) hadn't been initialised at the point of use.
Fix this by removing it and adjusting the two callers to use the
`filters` flow and take appropriate action on error.
Default to hiding the search operators, and provide a new toolbar icon
(always visible) to show them.
The toolbar icon is displayed with a badge if any operators are present.
Adjust the operator display to three horizontal scrolling rows, to
further limit the maximum amount of vertical space the operators use.
Previously re-binding the tag's text wouldn't re-measure the layout when
the text changed. So scrolling down a longer tag could be placed in a
textview that previously held a shorter tag.
Then it was cut off and the user couldn't see what the tag was. Use
`wrap_content` so size is measured when the content changes.
Mastodon supports in-query search operators, such as `has:image`,
`language:en`, or `in:library`. Previously the user had to enter them in
to the query directly.
This provides a chip-based UI that allows the user to set values for
these operators.
## Server
- Add new search capabilities to record the faceted search features the
server reports.
- Update definitions for Mastodon, Friendica, and GoToSocial to specify
which versions of the operations they support.
## SearchOperator / SearchOperatorViewData
- Represents each supported operator and associated viewdata.
## SearchActivity / activity_search.xml
- Conditionally display a chip for each facet depending on the server's
level of support.
- Implement the UI for each chip. They display dialogs of varying levels
of complexity depending on the underlying operation.
## FragmentSearch
- Display the progress as a LinearProgressIndicator instead of an
indeterminate ProgressBar. This makes it more visible under the search
facets.
Previously, if a status was filtered with "WARN" and was shown in the
timeline with the name of the filter, and the user then decided to
change
that filter, they had to:
1. Open the left navigation menu
2. Navigate to "Account preferences"
3. Open "Filters"
4. Find the filter they want to edit, tap it
5. Make the change, and save
6. "Back" to the list of filters
7. "Back" to "Account preferences"
8. "Back" to the timeline
That's a lot of clicks for a simple action.
Change this. Now the filtered status includes an "Edit filter" button
that takes the user directly to step 5, and when they press "Back" they
return directly to the timeline.
To do this create a new filter action, `onEditFilterById`. Update the
listeners to launch `EditFilterActivity` if appropriate.
Modify `item_status_filtered.xml` to show the new button.
Update the accessibility delegate to show just the "Show anyway" and
"Edit filter" actions. Modify `FilterableStatusViewHolder` to expose
the information it needs to do this.
Previous code always focused the search query. This meant that if the
user:
1. Searched for something
2. Opened a result (post, hashtag, account)
3. Navigated back to the search results
then because the query was focused the soft-keyboard would open,
obscuring the list of results. The user had to press "Back" again to
dismiss the keyboard.
New code only focuses the search query view if it is empty. This allows
the user to come back to the list of results and immediately open a new
result.
Previous code set `doOnTextChanged` listener for the content warning
*after* the initial value had been set. This meant the initial content
warning text was not included when calculating the status' initial
length.
Fix that by setting the listener before the text is set.
Fixes#815
The previous code had a number of problems, including:
- Calls to the filters API were scattered through UI and viewmodel code.
- Repeated places where the differences between the v1 and v2 Mastodon
filters API had to be handled.
- UI and viewmodel code using the network filter classes, which tied
them to the API implementation.
- Error handling was inconsistent.
Fix this.
## FiltersRepository
- All filter management now goes through `FiltersRepository`.
- `FiltersRepository` exposes the current set of filters as a
`StateFlow`, and automatically updates it when the current server
changes or any changes to filters are made. This makes
`FilterChangeEvent` obsolete.
- Other operations on filters are exposed through `FiltersRepository` as
functions for viewmodels to call.
- Within the bulk of the app a new `Filter` class is used to represent a
filter; handling the differences between the v1 and v2 APIs is
encapsulated in `FiltersRepository`.
- Represent errors when handling filters as subclasses of `PachliError`,
and use `Result<V, E>` throughout, including using `ApiResult` for all
filter API results.
- Provide different types to distinguish between new-and-unsaved
filters, new-and-unsaved keywords, and in-progress edits to filters.
## Editing filters
- Accept an optional complete filter, or filter ID, as parameters in the
intent that launches `EditFilterActivity`. Pass those to the viewmodel
using assisted injection so the viewmodel has the info immediately.
- In the viewmodel use a new `FilterViewData` type to model the data
used to display and edit the filter.
- Start using the UiSuccess/UiError model. Refrain from cutting over to
full the action implementation as that would be a much larger change.
- Use `FiltersRepository` instead of making any API calls directly.
## Listing filters
- Use `FiltersRepository` instead of making any API calls directly.
## EventHub
- Remove `FilterChangedEvent`. Update everywhere that used it to use the
flow from `FiltersRepository`.
Previous code blindly inserted commas and semi-colons as separators
between the components of a content description. If some of those
components were null you could have a content description that looked
like "... , , , ..." or similar, and the repeated reading of "comma" by
screen readers was jarring and reduced accessibility.
Fix this by inserting punctuation only where necessary, building up the
string piece by piece instead of using a string resource with hardcoded
punctuation.
Fixes#791.
When autocompleting hashtags while composing a status the previous code
showed the hashtags in the same order they're returned by the server,
with no additional information.
This doesn't allow the user to make an informed choice about which
hashtag might be better to use. For example, trying to choose between
"#nivenly" and "#NivenlyFoundation".
To fix that, include the hashtag's usage when receiving data from the
server. Sum that, and show it to the user in the hashtag list. Sort the
hashtags by popularity, most popular first.
