Previously, handling a HEAD request on the chapter download endpoint was inefficient as it triggered the full CBZ file generation process in-memory just to retrieve metadata like Content-Length and Content-Disposition. This caused unnecessary latency especially for OPDS clients.
This commit introduces a separate, lightweight path for HEAD requests.
- A new `getCbzMetadataForDownload` method is added to `ChapterDownloadHelper` to calculate the filename and file size without generating an archive stream.
- The `ChaptersFilesProvider` interface is updated with a `getArchiveSize()` method, implemented by both `ArchiveProvider` and `FolderProvider`, to retrieve the total size.
- The `MangaController` now differentiates between GET and HEAD methods, invoking the appropriate helper to ensure HEAD requests are served instantly with only the required metadata.
* Fix early exit on download for existing download for FolderProvider
The current check only worked for the "ArchiveProvider". The "FolderProvider" never moved the existing download to the cache folder.
In case the existing download is considered to be reusable, there is no need to proceed with the download logic.
* Fix "ArchiveProvider#extractExistingDownload"
The "ChaptersFilesProvider#extractExistingDownload" expects the download to be extracted into the final download folder.
However, the "ArchiveProvider" extracted the download into the chapter download cache folder.
* Add chapter download function call requirements
* Improve Downloads Handling
* Update known pagecount for downloaded chapters
* Get fresh data for downloadReady
* Format
* Assume downloaded if first page is found
* Filter out ComicInfoFile
* Añadiendo algunos cambios iniciales para probar OPDS
* Add suport to OPDS v1.2
* Added support for OPDS-PSE and reorganized controllers
* Rename chapterIndex to chapterId in the API and controller, and update descriptions in OPDS
* Refactor OPDS to use formatted timestamps and proxy thumbnail URLs
* Refactor OPDS to use formatted timestamps and proxy thumbnail URLs
* Update Manga API to download chapters cbz using only chapterId and improve chapter download query
* Optimize OPDS queries
* Update Manga API to download chapters cbz using only chapterId and improve chapter download query
* Optimize OPDS queries
* Use SourceDataClass to map sources and optimize thumbnail URL retrieval
* Kotlin lint errors in ChapterDownloadHelper and Opds
* Kotlin lint errors in ChapterDownloadHelper and Opds
* Properly check for first page in cbz files
The download check for cbz files only checked if the archive existed but didn't check for the first page
* Streamline getImageImpl of ChapterDownloadProviders
* Exclude comic info file from page list
In case the download folder did not contain any page files, only the comic info file existed, which caused the download check to incorrectly detect the first page
* Add logging to ChapterForDownload#asDownloadReady
* Switch to new Ktlint plugin
* Add ktlintCheck to PR builds
* Run formatter
* Put ktlint version in libs toml
* Fix lint
* Use Zip4Java from libs.toml
* Make server config value changes subscribable
* Make server config value changes subscribable - Update usage
* Add util functions to listen to server config value changes
* Listen to server config value changes - Auto backups
* Listen to server config value changes - Auto global update
* Listen to server config value changes - WebUI auto updates
* Listen to server config value changes - Javalin update ip and port
* Listen to server config value changes - Update socks proxy
* Listen to server config value changes - Update debug log level
* Listen to server config value changes - Update system tray icon
* Update config values one at a time
In case settings are changed in quick succession it's possible that each setting update reverts the change of the previous changed setting because the internal config hasn't been updated yet.
E.g.
1. settingA changed
2. settingB changed
3. settingA updates config file
4. settingB updates config file (internal config hasn't been updated yet with change from settingA)
5. settingA updates internal config (settingA updated)
6. settingB updates internal config (settingB updated, settingA outdated)
now settingA is unchanged because settingB reverted its change while updating the config with its new value
* Always add log interceptor to OkHttpClient
In case debug logs are disabled then the KotlinLogging log level will be set to level > debug and thus, these logs won't get logged
* Rename "maxParallelUpdateRequests" to "maxSourcesInParallel"
* Use server setting "maxSourcesInParallel" for downloads
* Listen to server config value changes - downloads

* Move files into sub packages
* Further abstract "DownloadedFilesProvider"

* Download and delete permanent thumbnails
When adding/removing manga from/to the library make sure the permanent thumbnail files will get handled properly
* Move thumbnail cache to actual temp folder
* Rename "mangaDownloadsRoot" to "downloadRoot"
* Move manga downloads into "mangas" subfolder
* Clear downloaded thumbnail
* Separate cache dir from download dir
* Move downloader logic outside of caching/image download logic
* remove unnecessary method duplication
* moved download logic inside download provider
* optimize and handle partial downloads
* made code review changes
