Refactor notifications to Kotlin & paging #4026

connyduck · 2023-09-19T19:10:40Z

This refactors the NotificationsFragment and related classes to Kotlin & paging.
While trying to preserve as much of the original behavior as possible, this adds the following improvements as well:

The "show notifications filter" preference was added again
The "load more" button now has a background ripple effect when clicked
The "legal" report category of Mastodon 4.2 is now supported in report notifications
Unknown notifications now display "unknown notification type" instead of an empty line

Other code quality improvements:

All views from xml layouts are now referenced via ViewBindings
the classes responsible for showing system notifications were moved to a new package systemnotifications while the classes from this refactoring are in notifications
the id of the local Tusky account is now called tuskyAccountId in all places I could find

closes #3429

The basic database setup is done, it is a bit more complicated than the timeline one and needs some cleanup but works fine. @charlag maybe you can have a look at it, I would be very interested in your opinion.
I think it would be nice to not have duplicate tables
Merging NotificationAccountEntity and TimelineAccountEntity should be easy.
NotificationStatusEntity and TimelineStatusEntity not so much, since the timeline table is used for the home timeline and I can't just mix other statuses in there. Maybe add a boolean flag isInHomeTimeline?
Thoughts?

in the end we should give each class here a one-sentence doc explaining what they are for

I was confused for a while before I realized that this class is not actually a DB table

I couldn't get too deeply into it but as far as I understand you did the same trick as with posts, just more complicated. Nice!

I think merging accounts could work if we can take care of cleanup but it gets a bit complicated.

We could merge statuses but it would be a lot of work. We would need a table with just IDs of the posts in timeline and a separate table with just posts (that's how Masto work internally too, with timelines being in Redis and posts in db). Then we could cache arbitrary posts in there.

I think at least for now your approach makes a lot of sense?

yes

+    private fun bindViewHolder(viewHolder: RecyclerView.ViewHolder, position: Int, payloads: List<Any>?) {


The payloads argument in a RecyclerView.Adapter is actually never null, it will be an empty list by default. You can change all the associated methods signatures to non-null.

I still recommend to change all the payloads arguments to be non-null, then all the associated .isNullOrEmpty() tests to .isEmpty()

You don't need to change the upstream dispatcher if you already specify it in pagingData.map(<Dispatcher>) and pagingData.filter(<Dispatcher>).
It's probably better to keep this line but remove the custom dispatcher for map and filter.

+                binding.notificationContent.visibility =


You can also use ktx extension properties for view visibility:

binding.notificationContent.isVisible = statusViewData.isExpanded

Note that the custom View.visible extension method used in the project serves the same purpose with a different syntax.

Same remark here, it's probably overkill to specify a dispatcher both here and in flowOn()

The menu doesn't show up anymore after merging #4026. I assume this was unintentional since the Fragment still implements `MenuProvider`.

The option was removed in #3877, then forgotten to be added again in #4015. #4026 added it again, but took to long to merge, so we made #4225 as well and that is how we ended up with the option twice.
