- Use format strings so any overhead of building the string is only
incurred if the message is actually logged
- Pass throwables as the first parameter so they are logged with the
stacktrace
Moshi is faster to decode JSON at runtime, is actively maintained, has a
smaller memory and method footprint, and a slightly smaller APK size.
Moshi also correctly creates default constructor arguments instead of
leaving them null, which was a source of `NullPointerExceptions` when
using Gson.
The conversion broadly consisted of:
- Adding `@JsonClass(generateAdapter = true)` to data classes that
marshall to/from JSON.
- Replacing `@SerializedName(value = ...)` with `@Json(name = ...)`.
- Replacing Gson instances with Moshi in Retrofit, Hilt, and tests.
- Using Moshi adapters to marshall to/from JSON instead of Gson `toJson`
/ `fromJson`.
- Deleting `Rfc3339DateJsonAdapter` and related code, and using the
equivalent adapter bundled with Moshi.
- Rewriting `GuardedBooleanAdapter` as a more generic `GuardedAdapter`.
- Deleting unused ProGuard rules; Moshi generates adapters using code
generation, not runtime reflection.
The conversion surfaced some bugs which have been fixed.
- Not all audio attachments have attachment size metadata. Don't show
the attachment preview if the metadata is missing.
- Some `throwable` were not being logged correctly.
- The wrong type was being used when parsing the response when sending a
scheduled status.
- Exceptions other than `HttpException` or `IoException` would also
cause a status to be resent. If there's a JSON error parsing a response
the status would be repeatedly sent.
- In tests strings containing error responses were not valid JSON.
- Workaround Mastodon a bug and ensure `filter.keywords` is populated,

Previously, `AboutActivity` had buttons and links to show the privacy
policy and licenses of dependencies.
Change this to a selection of fragments in tabs, one tab each for:
- General "About" information
- Licenses
- Privacy Policy
The information shown hasn't changed, but this lays the groundwork for
including additional tabs in the future for information like server
rules, detected capabilities, or troubleshooting information.
Release builds normally strip out all logging to reduce the number of
disk writes and reduce UI jank.
These logs would still be useful in user error reports from orange
builds. To preseve them:
- Implement a simple `RingBuffer`.
- Create `TreeRing`, a `Timber` `Tree` logger that logs to a
`RingBuffer` instance in orange release builds.
- Create `TreeRingCollector`, called when ACRA reports are generated,
which includes the contents of the ring buffer in the report.
- Enable desugaring to allow the use of java.time libraries on older
Android versions.
- Disable ProGuard obfuscation of class names as the obfuscation adds
additional de-obfuscation steps when handling error reports from users.
Getting error reports with logs of strange behaviour is useful even if
the app doesn't crash.
Move crash reporting in to `core.activity`, and provide a menu option
(in orange builds) to trigger a non-fatal crash report that is handled
the same way (i.e., sent by e-mail) as a regular crash report.
`BaseActivity` has to be able to create and handle menus, so adjust
subclasses to call the superclass when necessary.
Update `tools/mvstring` to be able to move strings between different
flavour directories, not just `main`.
Continue modularisation by moving activities in the "About" feature to a
new `feature.about` module.
Implement `feature.about:
- Move `AboutActivity`, `LicenseActivity`, and `PrivacyPolicyActivity`
here.
- Update `markdown2resource` plugin to work with libraries
Implement `core.data`:
- Types and repositories used through the app
- Move `InstanceInfo` and `InstanceInfoRepository` here so they are
available to `feature.about`.
Implement `core.ui`:
- App-specific views, spans, and other UI content
- Move `ClickableSpanTextView` and `NoUnderlineURLSpan` here so they are
available to `feature.about`.
Continue modularisation by moving core activity classes that almost all
activities depende on to a `core.activity` module. This includes
core "helper" classes as well.
Implement core.activity:
- Contains BaseActivity, BottomSheetActivity
- Contains LinkHelper and other utility classes used by activities
Implement core.common.extensions:
- Move ViewBindingExtensions and ViewExtensions here
Implement core.common.util:
- Move BlurHashDecoder and VersionName here
Implement core.designsystem:
- Holds common resources (animations, colours, drawables, etc) used
through the app
- Import "core.designsystem.R as DR" through the app to distinguish
from the module's own resources
Implement feature.login:
- Move the LoginActivity and related code/resources to its own module
Implement tools/mvstring
- Moves string resources (and all translations) from one module to
another
Previously when the user interacted with a status the operation (reblog,
favourite, etc) travels through multiple layers of code, carrying with
it the position of the item in the list that the user operated on.
At some point the status is retrieved from the list using its position
so that the correct status ID can be used in the network operation.
If this happens while the list is also refreshing there's a possible
race condition, and the original status' position may have changed in
the list. Looking up the status by position to determine which status to
perform the action on may cause the action to happen on the wrong
status.
Fix this by passing the status' viewdata to any actions instead of its
position. This includes all the information necessary to make the API
call, so there is no chance of a race.
This is quite an involved change because there are three types of
viewdata:
- `StatusViewData`, used for regular timelines
- `NotificationViewData`, used for notifications, may wrap a status that
can be operated on
- `ConversationViewData`, used for conversations, does wrap a status
The previous code treated them all differently, which is probably why it
operated by position instead of type.
The high level fix is to:
1. Create an interface, `IStatusViewData`, that contains the data
exposed by any viewdata that contains a status.
2. Implement the interface in `StatusViewData`, `NotificationViewData`,
and `ConversationViewData`.
3. Change the code that operates on viewdata (`SFragment`,
`StatusActionListener`, etc) to be generic over anything that implements
`IStatusViewData`.
4. Change the code that handles actions to pass the viewdata instead of
the position.
Fixes#370
Previous code could return an error on Friendica version strings like
`2024.03-dev-1547`.
Fix this:
- Extend the list of explicitly supported servers to include Fedibird,
Friendica, Glitch, Hometown, Iceshrimp, Pixelfed, and Sharkey.
- Add version parsing routines for these servers.
- Test the version parsing routines fetching every server and version
seen by Fediverse Observer (~ 2,000 servers) and ensuring that the
server and version information can be parsed.
Improve the error message:
- Show the hostname with a `ServerRepository` error
Clean up the code:
- Remove the custom `resultOf` and `mapResult` functions, they have
equivalents in newer versions of the library (like `runSuspendCatching`)
Fixes#372
Commit 993b7469 inadvertently broke this by removing the @SerializedName
annotation, so the user's display name was always null and the UI fell
back to showing the username.
Fixes#371
The previous code unilaterally enabled filter functionality. Some
Mastodon-like servers -- like GoToSocial -- do not support filters, and
this resulted in user visible error messages when connecting to those
servers.
To fix this:
- Extend the set of supported server capabilities to include client and
server side filtering.
- Disable the filter preferences if the server does not support filters
and show a message explaining why it's disabled.
Extend the capabilities model to support this:
- Fetch server software name and version from the nodeinfo endpoints
(implementing the nodeinfo API and schema)
- Extend the use of kotlin-result to provide hierarchies of Error
classes and demonstrate how to chain errors and display more informative
messages without using exceptions.
Fixes#343
The previous code was serialising the `TabKind` enum without the `_`, so
when it was converted back to the enum name (which has a `_`) it failed
and immediately crashed.
Fixes#306
If a status was part of a thread, and it was not the "detailed" status,
and it had been translated, then the view data was marked as "show the
translation". But the translation was not loaded, so the status content
appeared as empty.
Fix that by loading the translated content of all statuses in the thead
and ensure that the translated content is rendered.
Throw an `IllegalStateException` in debug builds to catch any future
occurrences of this.
Fixes#281
Mastodon counts post lengths by considering emojis to be single
characters, no matter how many unicode code points they are composed of.
So "😜" has length 1.
Pachli was using `String.length`, which considers "😜" as length 2.
Correct the calculation by using a BreakIterator to count the characters
in the string, which treats multi-character emojis as a length 1.
Poll options had a similar problem, exacerbated by the Mastodon web UI
also having the same problem, see
https://github.com/mastodon/mastodon/issues/28336.
Fix that by creating `MastodonLengthFilter`, an `InputFilter` that does
the right thing for regular text that may contain emojis.
See also https://github.com/tuskyapp/Tusky/pull/4152, which has the fix
for status length but not polls.

Roles for the logged in user appeared in Mastodon 4.0.0 and can be
displayed on the user's profile screen.
Show them as chips, adjusting the display of the existing "Follows you"
and "Bot" indicators to make allowances for this.
Roles can have a custom colour assigned by the server admin. This is
blended with the app colour so it is not too jarring in the display.

The previous code generally started an activity by having the activity
provide a method in a companion object that returns the relevant intent,
possibly taking additional parameters that will be included in the
intent as extras.
E.g., if A wants to start B, B provides the method that returns the
intent that starts B.
This introduces a dependency between A and B.
This is worse if B also wants to start A.
For example, if A is `StatusListActivity` and B is`ViewThreadActivity`.
The user might click a status in `StatusListActivity` to view the
thread, starting `ViewThreadActivity`. But from the thread they might
click a hashtag to view the list of statuses with that hashtag. Now
`StatusListActivity` and `ViewThreadActivity` have a circular
dependency.
Even if that doesn't happen the dependency means that any changes to B
will trigger a rebuild of A, even if the changes to B are not relevant.
Break this dependency by adding a `:core:navigation` module with an
`app.pachli.core.navigation` package that contains `Intent` subclasses
that should be used instead. The `quadrant` plugin is used to generate
constants that can be used to launch activities by name instead of by
class, breaking the dependency chain.
The plugin uses the `Activity` names from the manifest, so when an
activity is moved in the future the constant will automatically update
to reflect the new package name.
If the activity's intent requires specific extras those are passed via
the constructor, with companion object methods to extract them from the
intent.
Using the intent classes from this package is enforced by a lint
`IntentDetector` which will warn if any intents are created using a
class literal.
See #291
The package wasn't renamed when it was moved, so was still
`app.pachli.components.timeline`, instead of the new location,
`app.pachli.core.network.model`.
The existing code base is a single monolithic module. This is relatively
simple to configure, but many of the tasks to compile the module and
produce the final app have to run in series.
This is unnecessarily slow.
This change starts to split the code in to multiple modules, which are:
- :core:account - AccountManager, to break a dependency cycle
- :core:common - low level types or utilities used in many other modules
- :core:database - database types, DAOs, and DI infrastructure
- :core:network - network types, API definitions, and DI infrastructure
- :core:preferences - shared preferences definitions and DI
infrastructure
- :core:testing - fakes and rules used across different modules
Benchmarking with gradle-profiler shows a ~ 17% reduction in incremental
build times after an ABI change. That will improve further as more code
is moved to modules.
The rough mechanics of the changes are:
- Create the modules, and move existing files in to them. This causes a
lot of churn in import arguments.
- Convert build.gradle files to build.gradle.kts
- Separate out the data required to display a tab (`TabViewData`) from
the data required to configure a tab (`TabData`) to avoid circular
dependencies.
- Abstract the repeated build logic shared between the modules in to
a set of plugins under `build-logic/`, to simplify configuration of
the application and library builds.
- Be explicit that some nullable types are non-null at time of use.
Nullable properties in types imported from modules generally can't be
smart cast to non-null. There's a detailed discussion of why this
restriction exists at
https://discuss.kotlinlang.org/t/what-is-the-reason-behind-smart-cast-being-impossible-to-perform-when-referenced-class-is-in-another-module/2201.
The changes highlight design problems with the current code, including:
- The main application code is too tightly coupled to the network types
- Too many values are declared unnecessarily nullable
- Dependency cycles between code that make modularisation difficult
Future changes will add more modules.
