* Drop duplicate initial call in Preference.asHotFlow
Preference.changes() always starts by returning the current value of
the preference, so asHotFlow calls block twice on the initial value.
Possible breaking change: As implemented, asHotFlow ran block(get())
before returning the flow. After this change, the first call to block
will run within the flow collection. This might cause concurrency
issues if the flow collection is late to execute.
* Inline Preference.asHotFlow
The Preference.changes().onEach().launchIn() pattern is used widely,
so the asHotFlow extension method is redundant.
Inline readImageHeaderSubscription in PageHolder
Inline readImageHeaderSubscription in PagerPageHolder and
WebtoonPageHolder by converting setImage() into a suspend function.
The image processing runs in the loadPageAndProcessStatus
continuation.
Use suspendCancellableCoroutine as a substitute for doOnUnsubscribe
in WebtoonPageHolder.
Closing openStream after the frame.setImage but before the PageHolder
is recycled causes the page display to fail for reasons that are not
currently understood.
Remove subscription handling from WebtoonViewer/WebtoonBaseHolder as
it is no longer used.
Inline statusJob into loadJob, using supervisorScope to load the page
and track status changes in parallel.
- supervisorScope does not complete until both the child loadPage
coroutine and statusFlow.collectLatest have completed.
- Cancelling supervisorScope cancels the child loadPage coroutine and
statusFlow.collectLatest.
- Use supervisorScope instead of coroutineScope to let status
collection continue if loadPage fails.
Inline progressJob into loadJob, using collectLatest's cancellation
to avoid cancelling the progressFlow collection explicitly.
- collectLatest cancels the previous action block when the flow
emits a new value. This means the DOWNLOAD_IMAGE
progressFlow.collectLatest gets automatically cancelled when
statusFlow emits a new state.
Convert launchLoadJob to suspend function, move job launch to caller,
and rename as loadPageAndProcessStatus.
Fixup for e4bc8990 (#8955)
HttpSource.fetchImage() uses Call.asObservableSuccess(), which
cancels the call on unsubscribe. This causes the call to be cancelled
before it is used, leading to a "java.net.SocketException: Socket is
closed" when trying to use the response in putImageToCache().
To fix this, use Call.awaitSuccess() via a new HttpSource.getImage()
suspending function. This addition to source-api is only intended for
app use, so it will not be added to the extensions-api stubs.
Fixes#8881
The actual issue is that the ViewModel migration actually differs between what the current `init` block
and previous `onSave` methods did; where the `init` block does not get triggered on saving the
instance on config changes.
Not entirely sure why onSaveInstanceState was explicitly avoided for config changes before, but we
just do it all the time now and end up updating the requestedPage with the current page.
* Convert downloader Observable to flow
Uses `runInterruptible` to turn the blocking call to `queue.take()`
into a cancellable call.
Flow collection is ended by cancelling the scope in `recycle`. This
means the `HttpPageLoader` can't be reused after calling `recycle`,
but this was true with the `Observable` as well.)
* Convert load Observables to suspending function
Inlining the Observables allows for some simplification of the error
handling. Behavior should be otherwise identical.
* Convert cleanup Completable to coroutine
Uses global `launchIO`, not ideal but similar to previous behavior.
Can't be scheduled on the local `scope` as this runs after `scope` is
cancelled.
