Types of changes

  • I have read the CONTRIBUTING document.
  • My code follows the code style of this project.
  • I have updated the documentation accordingly.
  • I have added tests to cover my changes.
  • All new and existing tests passed.
  • This is NOT translation related.

I'm trying to move most of the code in the HomeActivity to the viewmodel and to use Dispatchers.IO for all operations that use the database or the api.

I'm already doing a lot of cleaning in here https://gitea.amine-louveau.fr/Louvorg/ReaderForSelfoss-multiplatform/src/branch/feature/api_timeout_and_settings_cleaning

Maybe wait to continue on this PR ?

I did a quick review, but as I'll clean some code, don't spend much time on this for now.

I'll try to finish my changes pretty soon.

The view should call the repository and get the data from there.

This seams too complicated.

Storing the items would allow sharing the same data across all activities without passing it around and it can be used to prevent making an api call every time you close an article and come back to the article list; which is in fact unnecessary.

this is intended to fetch the new articles as soon as possible.

Personal use case: selfoss fetches new articles every 15 minutes, in the application I will be reading an article in a couple of minutes and then going back to the articles list to select another one.
Every time I go back to the articles list the fetching starts, which is annoying because of the loading spinner appearing at the top each time.
I have no need for it to be updating so often, and most of those updates are useless anyways because most of the times no new items will be available on the server.
I can manually update the articles list at any time if I wish or if I finished reading all the available ones.

I remember someone else opened an issue some time ago complaining about the frequency of updates as well.

Why don't you swipe between the articles ?

I remember someone else opened an issue some time ago complaining about the frequency of updates as well.

That user in particular had issues with the tags and sources loading. They had a lot of them. That's why the update_sources setting was added.

I have many articles to read and I do not read them in order, it is easier for me to get back to the list and select from there what I want to read rather than swiping through until I find something interesting.

That makes sens, but I still thinks the app needs to refresh onReload.

We could try to find a way to differenciate between "going back from another activity of the app" and "relaunching the app after it being in the background". This would solve both our use cases.

updateRemote doesn't necessarily have to be there, I have done it because I think it makes it easier to read through the activity code.
getItems in the viewmodel allows storing the items in the viewmodel which might provide some advantages.

I find it more difficult to read. Moving some code that's only available and usable in a specific activity in a shared ViewModel isn't necessary.

There is no need to refactor thing this soon. If there is currently no need to have the items in the viewmodel, there is no need to have them here.

updateApiVersion() and reloadBadges() both check the network availability. This change isn't needed.

When init is run the connectivity check always fails.
This allows retrieving the badges every time connectivity gets back.
We could include here all operations that should be run as soon as network connectivity is available, such as fetching sources and tags.

When init is run the connectivity check always fails.

So this is a bug that should be fixed instead of having this workaround.

This allows retrieving the badges every time connectivity gets back.

This isn't a good thing, since items arn't refreshed on connectivity change. We would have a difference in the items count and the badge count.

We could include here all operations that should be run as soon as network connectivity is available, such as fetching sources and tags.

Fetching sources and tags can be limited via a update_sources. It's also something that shouldn't be done as much as items fetching.

I guess that most of the stuff in this PR isn't very useful since what we concluded discussing.
I can close this and make a new one only including the changes which are useful after you merge the one you're working on.
