These are basically 1-to-1 replacements for the existing RxJava APIs.
This will make the initial migration off of RxJava simpler. We'll
revisit the actual call flows in followup versions of the API.
* Serialize whole chapter numbers without decimal point and add library categories to genre
* added Tachiyomi specific ComicInfo Category field
* lint
* implemented requested changes
* Rename removeFromQueueByPredicate to removeFromQueueIf
Follow-up to PR comment in #9511
* Make Download hashCode stable
Mutating pages would previously change the Download hashCode, which
breaks HashMap lookups.
* Convert Donwloader subscription to coroutine
Replace downloadsRelay with activeDownloadsFlow. Instead of managing
a PublishRelay independent from the queue, derive a Flow of active
downloads directly from the queue StateFlow. (This will allow
updating the queue without pausing the downloader, to be done in a
follow-up PR.)
When a download completes successfully, the downloads is removed from
queueState. This updates activeDownloadsFlow and causes the
downloaderJob start the download job for the next active download.
When a download fails, the download is left in the queue, so
queueState is not modified. To make activeDownloadsFlow update
without a change to queueState, use transformLatest and use the
Download statusFlows to suspend until a download reaches the ERROR
state.
To avoid stopping and starting downloads every time
activeDownloadsFlow emits a new value, maintain a map of current
download Jobs and only start/stop jobs in the difference between
downloadJobs and activeDownloads. To make sure all child download
jobs are cancelled when the top-level downloader job is cancelled,
use supervisorScope.
* Remove obsolete main thread references in Downloader
Thread safety of the queue state used to be guaranteed by running all
queue mutation on the main thread, but this has not been true for
some time. Since the queue state is now backed by a StateFlow,
queueState can be safely updated by any thread.
Fetch each source image URL immediately before downloading each image
instead of fetching all URLs and then downloading all images.
Source image URLs may change, so the downloader may fail if there is
too long a delay between fetching the image URL and downloading the
image.
* change the directory's name for a download when the chapter's name is only composed of numbers or is blank
* maj in case the chapter name is blank or empty
* clean code
This partially reverts commit 2769525b2c.
Keeps the change to silently ignore spliting errors since it falls back to
the original images in those cases.
Downloader.stop is now the sole responsible for stopping the
DownloadService. This will help cleanly removing
DownloadService.stop when migrating to coroutines.
* Rename functions for DownloadService internal use
* Call DownloadService.start via DownloadManager
* Inline DownloadService.stop into pauseDownloads
* Inline DownloadService.stop into clearQueue
NotificationReceiver will now also stop the DownloadService when
receiving ACTION_CLEAR_DOWNLOADS.
* Provide DownloadService.isRunning via DownloadManager
1:1 translation from the RxJava implementation, should match the
previous behavior.
Dropped the return value from functions of the form
```
fun foo(t: T, ...): Observable<T>
```
where the Observable produced the original argument `t`.
The caller already has the result if necessary.
While this conversion is not flow-based overall, some sections use
flows to use the flatMapMerge and retryWhen operators.
Removed RetryWithDelay as it was only used here.
Inlined fetchAllImageUrlsFromPageList instead of converting it to a
suspending equivalent. fetchAllImageUrlsFromPageList is no longer
used in the app, but was not removed as it is part of source-api.
(However, it does not seem to be used exposed in extensions-lib or
used in tachiyomi-extensions.)
runBlocking is used as a temporary stop-gap.
When restarting a download, the page count would display as 0 until
the first page download completion, after all the existing pages were
rechecked.
To fix, calculate downloadedImages from pages instead of relying on
the downloader to reset and increment the count.
* Misc cleanup
- Replace !List.isEmpty with List.isNotEmpty
- Remove redundant case in MoreScreenModel
- Drop no-op StateFlow.catch
- From lint warning:
> SharedFlow never completes, so this operator typically has not
> effect, it can only catch exceptions from 'onSubscribe' operator
* Convert DownloadQueue queue to MutableStateFlow
Replace delegation to a MutableList with an internal
MutableStateFlow<List>.
In order to avoid modifying every usage of the queue as a list, add
passthrough functions for the currently used list functions. This
should be later refactored, possibly by inlining DownloadQueue
into Downloader.
DownloadQueue.updates was a SharedFlow which updated every time a
change was made to the queue. This is now equivalent to the queue
StateFlow.
Simultaneous assignments to _state.value could cause concurrency
issues. To avoid this, always modify the queue using _state.update.
* Add Download.statusFlow/progressFlow
progressFlow is based on the DownloadQueueScreenModel implementation
rather than the DownloadQueue implementation.
* Reimplement DownloadQueue.statusFlow/progressFlow
Use StateFlow<List<T>>.flatMapLatest() and List<Flow<T>>.merge() to
replicate the effect of PublishSubject.
Use drop(1) to avoid re-emitting the state of each download each time
the merged flow is recreated.
* fixup! Reimplement DownloadQueue.statusFlow/progressFlow
* Simplify DownloadService wake lock handling
_isRunning is only modified in onCreate/onDestroy, so the listener
job is redundant.
* Drop superclass calls to Service.onCreate/onDestroy
From https://developer.android.com/guide/components/services
> Note: Unlike the activity lifecycle callback methods, you are not

Fixes#8962.
withTimeout throws a TimeoutCancellationException if the timeout
expires. To avoid crashing renewalJob when there are no extensions,
use withTimeoutOrNull which does not throw on timeout.
