+/**
+ * A cache that holds strong references to a limited number of values. Each time
+ * a value is accessed, it is moved to the head of a queue. When a value is
+ * added to a full cache, the value at the end of that queue is evicted and may
+ * become eligible for garbage collection.
+ *
+ * <p>If your cached values hold resources that need to be explicitly released,
+ * override {@link #entryRemoved}.
+ *
+ * <p>If a cache miss should be computed on demand for the corresponding keys,
+ * override {@link #create}. This simplifies the calling code, allowing it to
+ * assume a value will always be returned, even when there's a cache miss.
+ *
+ * <p>By default, the cache size is measured in the number of entries. Override
+ * {@link #sizeOf} to size the cache in different units. For example, this cache
+ * is limited to 4MiB of bitmaps:
+ * <pre>   {@code
+ *   int cacheSize = 4 * 1024 * 1024; // 4MiB
+ *   LruCache<String, Bitmap> bitmapCache = new LruCache<String, Bitmap>(cacheSize) {
+ *       protected int sizeOf(String key, Bitmap value) {
+ *           return value.getByteCount();
+ *       }
+ *   }}</pre>
+ *
+ * <p>This class is thread-safe. Perform multiple cache operations atomically by
+ * synchronizing on the cache: <pre>   {@code
+ *   synchronized (cache) {
+ *     if (cache.get(key) == null) {
+ *         cache.put(key, value);
+ *     }
+ *   }}</pre>
+ *
+ * <p>This class does not allow null to be used as a key or value. A return
+ * value of null from {@link #get}, {@link #put} or {@link #remove} is
+ * unambiguous: the key was not in the cache.
+ *
+ * <p>This class appeared in Android 3.1 (Honeycomb MR1); it's available as part
+ * of <a href="http://developer.android.com/sdk/compatibility-library.html">Android's
+ * Support Package</a> for earlier releases.

+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The

 You need these software packages installed in order to build the project

- Java Development Kit and Java Runtime Environment version 8 or newer(both Oracle JDK and OpenJDK works)
+- Java Development Kit version 21 or newer(we suggest using Zulu or Temurin instead of Oracle JDK)

 ### building the full-blown jar (Suwayomi-Server + Suwayomi-WebUI bundle)
 Run `./gradlew server:downloadWebUI server:shadowJar`, the resulting built jar file will be `server/build/Suwayomi-Server-vX.Y.Z-rxxx.jar`.

+#### WebView support (GNU/Linux)
+
+WebView support is implemented via [KCEF](https://github.com/DATL4G/KCEF).
+This is optional, and is only necessary to support some extensions.
+
+To have a functional WebView, several dependencies are required; aside from X11 libraries necessary for rendering Chromium, some JNI bindings are necessary: gluegen and jogl (found in Ubuntu as `libgluegen2-jni` and `libjogl2-jni`).
+Note that on some systems (e.g. Ubuntu), the JNI libraries are not automatically found, see below.
+
+A KCEF server is launched on startup, which loads the X11 libraries.
+If those are missing, you should see "Could not load 'jcef' library".
+If so, use `ldd ~/.local/share/Tachidesk/bin/kcef/libjcef.so | grep not` to figure out which libraries are not found on your system.
+
+The JNI bindings are only loaded when a browser is actually launched.
+This is done by extensions that rely on WebView, not by Suwayomi itself.
+If there is a problem loading the JNI libraries, you should see a message indicating the library and the search path.
+This search path includes the current working directory, if you do not want to modify system directories.
+
+Refer to the [Dockerfile](https://github.com/Suwayomi/Suwayomi-Server-docker/blob/main/Dockerfile) for more details.

+Suwayomi-Server configuration file is named `server.conf` and is located inside [the data directory](https://github.com/Suwayomi/Suwayomi-Server/wiki/The-Data-Directory).
+
+The configuration file is written in HOCON. Google is your friend if you want to know more. 
+
+**Note:** new keys might be added in the future. Suwayomi generally attempts to update your conf file automatically, but some keys may need to be updated manually.
+
+## Troubleshooting
+### I messed up my configuration file
+Suwayomi will create a default configuration file when one doesn't exist, you can delete `server.conf` to get a copy of the reference configuration file after a restart.
+
+### I am running Suwayomi in a headless environment (docker, NAS, VPS, etc.)
+- Set `server.systemTrayEnabled` to false, it will prevent Suwayomi to attempt to create a System Tray icon.
+- Set `server.initialOpenInBrowserEnabled`to false, it will prevent Suwayomi to attempt to open a browser on startup.
+
+### My Suwayomi data directory/downloads size is getting to big
+- Set `server.downloadsPath` to the desired path, if you only need to change where downloads are stored. You have to move/remove the existing downloads manually.
+- Set the special `server.rootDir` key if you need Suwayomi to use a custom data directory path, refer to [this section](#overriding-tachidesk-servers-data-directory-path). 
+
+## Configuration Options
+### Server ip and port bindings
+```conf
+server.ip = "0.0.0.0"
+server.port = 4567
+```
+- `server.ip` can be an IP or domain name.
+
+### Socks5 proxy
+```
+server.socksProxyEnabled = false
+server.socksProxyVersion = 5 # 4 or 5
+server.socksProxyHost = ""
+server.socksProxyPort = ""
+server.socksProxyUsername = ""
+server.socksProxyPassword = ""
+```
+This section directs Suwayomi to connect to the network through a proxy server. 
+
+An example configuration can be:
+```
+server.socksProxyEnabled = true
+server.socksProxyHost = "yourproxyhost.com"
+server.socksProxyPort = "8080"
+```
+
+### webUI
+```
+server.webUIEnabled = true
+server.initialOpenInBrowserEnabled = true
+server.webUIInterface = "browser" # "browser" or "electron"
+server.electronPath = ""
+server.webUIFlavor = "WebUI" # "WebUI" or "Custom"
+server.webUIChannel = preview # "BUNDLED" or "STABLE" or "PREVIEW"
+server.webUIUpdateCheckInterval = 23
+server.webUISubpath = ""
+```
+- `server.webUIEnabled` controls if Suwayomi will serve `Suwayomi-WebUI` and if it downloads/updates it on startup.
+- `server.initialOpenInBrowserEnabled` controls if Suwayomi will attempt to open a brwoser/electron window on startup, disabling this on headless servers is recommended.
+- `server.webUIInterface` which web interface Suwayomi should launch on startup, options are `"browser"` and `"electron"`
+- `server.electronPath` path of the main electron executable, should be in double quotes
+- `server.webUIFlavor` set `"WebUI"` to make the server download and update Suwayomi-WebUI automatically or `"Custom"` if you want the server to serve a custom web interface that you manage by yourself.
+  - Note: "Custom" would be useful if you want to test preview versions of Suwayomi-WebUI or when you are using or developing other web interfaces like the web version of Suwayomi-Sorayomi.
+- `server.webUIChannel` allows to choose which update channel to use (only valid when flavor is set to "WebUI"). Use `"BUNDLED"` to use the version included in the server download, `"STABLE"` to use the latest stable release or `"PREVIEW"` to use the latest preview release (potentially buggy).
+- `server.webUIUpdateCheckInterval` the interval time in hours at which to check for updates. Use `0` to disable update checking.
+- `server.webUISubpath` controls on which sub-path the UI is served; by default, it will be accessible on `/` (i.e. directly), with this setting it can also be set to appear at e.g. `/suwayomi`
+
+### Downloader
+```
+server.downloadAsCbz = true
+server.downloadsPath = ""
+server.autoDownloadNewChapters = false
+server.excludeEntryWithUnreadChapters = true
+server.autoDownloadNewChaptersLimit = 0
+server.autoDownloadIgnoreReUploads = false
+server.downloadConversions = {}
+```
+- `server.downloadAsCbz = true` configures Suwayomi to automatically compress chapters into CBZ.
+- `server.downloadsPath = ""` the path where manga downloads will be stored, if the value is empty, the default directory `downloads` inside [the data directory](https://github.com/Suwayomi/Suwayomi-Server/wiki/The-Data-Directory) will be used. If you are on Windows the slashes `\` needs to be doubled(`\\`) or replaced with `/`
+- `server.autoDownloadNewChapters = false` controls if Suwayomi should automatically download new chapters after a library update.
+- `server.excludeEntryWithUnreadChapters = true` controls if Suwayomi will download new chapters for titles with unread chapters (requires `server.autoDownloadNewChapters`).
+- `server.autoDownloadNewChaptersLimit = 0` sets how many chapters should be downloaded at most, `0` to disable the limit; if the limit is reached, new chapters will not be downloaded (requires `server.autoDownloadNewChapters`).
+- `server.autoDownloadIgnoreReUploads = false` controls if Suwayomi will re-download re-uploads on update (requires `server.autoDownloadNewChapters`).
+- `server.downloadConversions = {}` configures optional image conversions for all downloads. This is an [JSON object](https://en.wikipedia.org/wiki/JSON#Syntax), with the source image [mime type](https://en.wikipedia.org/wiki/Media_type) as the key and an object with the target mime type or url and options as value.  
+  The following options are all valid:  
+  ```
+  server.downloadConversions = { "image/webp" : { target : "image/jpeg", compressionLevel = 0.8 }}
+  # -- or --
+  server.downloadConversions."image/webp" = {
+    target = "image/jpeg"   # image type to convert to
+    compressionLevel = 0.8  # quality in range [0,1], leave away to use default compression
+  }
+  # -- a url example --
+  server.downloadConversions = { "default" : { target : "http://localhost:9999/convert" }}
+  # -- a url with all parameters example --
+  server.downloadConversions = { 
+      "default" : {
+          target : "http://localhost:9999/convert",
+          callTimeout : 10m,
+          connectTimeout : 10s,
+          headers : { 
+              "authorization" : "MyPassword"
+          }
+      }
+  }
+  ```  
+  A source mime type `default` can be used as fallback to convert all images; a target mime type of `none` can be used to disable conversion for a particular format.
+  
+  This is an example curl command for what Suwayomi-Server will send to the conversion url: `curl -X POST "http://localhost:9999/convert" -F "image=@cat.png;type=image/png"`
+- `server.serveConversions = {}` configures optional image conversions before serving the image to the client. It follows the same format as `server.downloadConversions`.
+

+### Authentication
+```
+server.authMode = "none" # none, basic_auth, simple_login or ui_login
+server.authUsername = "user"
+server.authPassword = "pass"
+server.jwtAudience = "suwayomi-server-api"
+server.jwtTokenExpiry = "5m"
+server.jwtRefreshExpiry = "60d"
+```
+- `server.authMode = "none"`: Since v2.1.1867, Suwayomi supports two modes of authentication. Enabling authentication is useful when hosting on a public network/the Internet. If you used the original `server.basicAuth*` variables, it will be automatically migrated.  
+  - `basic_auth` configures Suwayomi for [Basic access authentication](https://en.wikipedia.org/wiki/Basic_access_authentication).  
+  - `simple_login` works similarly to Basic Authentication, but presents a custom login page. The login is stored via a cookie and needs to be refreshed on every server restart or every 30 minutes.  
+  - Starting with v2.1.1894, another mode is available:
+    `ui_login` is a new [JWT](https://en.wikipedia.org/wiki/JSON_Web_Token)-based authentication scheme, which tightly integrates with the chosen UI. Instead of restricting access completely, this allows the user to still open the UI (e.g. WebUI). Unlike the other two modes, this means the login page is entirely customizable by the UI. The `jwt*` settings can be used to tune session duration in this mode.
+- `server.authUsername` the username value that you have to provide when authenticating.
+- `server.authPassword` the password value that you have to provide when authenticating.
+- `server.jwtAudience` is any string to be embedded into the JWT token. See `aud` field in [JWT](https://en.wikipedia.org/wiki/JSON_Web_Token#Standard_fields).
+- `server.jwtTokenExpiry` is the time any token is valid ("access token"); after expiry, the refresh token will be used to generate a new access token again without prompting for credentials.
+- `server.jwtRefreshExpiry` is the time the refresh token is valid. After it has expired, the user will be prompted to login again; before that, the session can be quietly refreshed using this token. Note the security implication in this: While the access token is valid, the server fully trusts the holder of that token. After the access token has expired, the refresh token can be used to obtain a new access token; only at this time can the session be terminated by the server.
+
+**Note**: Basic access authentication sends username and password in cleartext and is not completely secure over HTTP, it's recommended to pair this feature with a reverse proxy server like nginx and expose the server over HTTPS. Similarly, with `simple_login` and `ui_login`, the credentials are sent in cleartext on login, and the cookie/token is sent with every request. Also your browser caches the credentials/cookie, so you should be careful when accessing the server from non-private devices and use incognito mode.

+- `server.flareSolverrUrl = "http://localhost:8191"` sets the address where Suwayomi attempts to connect to FlareSolverr. The instance needs to run and be accessible from the server where Suwayomi is running for CloudFlare bypass to work.
+- `server.flareSolverrTimeout = 60` sets the timeout to wait for FlareSolverr to solve a given challenge in seconds.
+- `server.flareSolverrSessionName = "suwayomi"` sets the session name that FlareSolverr should use. Tells FlareSolverr which set of cookies to use.
+- `server.flareSolverrSessionTtl = 15` sets the time for how long sessions in FlareSolverr should live in minutes. After this time, FlareSolverr will forget cookies.
+- `server.flareSolverrAsResponseFallback = false` allows Suwayomi to use the contents of the request that FlareSolverr received in case Suwayomi sees a CloudFlare challenge but FlareSolverr does not (which prevents it from solving the challenge).
+
+**Note:** Byparr is a popular alternative to FlareSolverr. It uses the same API schema as FlareSolverr, so you can also configure the address of a Byparr instance in `server.flareSolverrUrl`.

+- `server.koreaderSyncDeviceId` a unique ID to identify Suwayomi at the KOReader Sync Server. Leave blank to auto-generate.
+- `server.koreaderSyncChecksumMethod` the method by which to identify chapters at the KOReader Sync Server. BINARY includes the entire contents of the chapter, and is thus more expensive, but may be convenient to catch updated chapters.
+- `server.koreaderSyncPercentageTolerance` when syncing read progress for a chapter from other devices, how much difference (absolute) is allowed to be ignored. When above this tolerance, Suwayomi's read progress will be replaced by the remote device's according to the specified strategy. The strategy is chosed from `server.koreaderSyncStrategyForward` and `server.koreaderSyncStrategyBackward` based on the timestamps of the last read.

+```
+- `server.databaseType` chooses which type of database to use. [H2](https://en.wikipedia.org/wiki/H2_Database_Engine) is the default; it is a simple file-based database for Java applications. Since it is only based on files without a server process, file corruption can be common when the server is not shut down properly. [PostgreSQL](https://en.wikipedia.org/wiki/PostgreSQL) is a popular cross-platform, stable database. To use PostgreSQL, you need to run an instance yourself.
+- `server.databaseUrl` the URL where to find the PostgreSQL server, including the database name.
+- `server.databaseUsername` the username with which to authenticate at the PostgreSQL instance.
+- `server.databasePassword` the username with which to authenticate at the PostgreSQL instance.
+- `server.useHikariConnectionPool` use Hikari Connection Pool to connect to the database.
+
+**Note:** The example [docker-compose.yml file](https://github.com/Suwayomi/Suwayomi-Server-docker/blob/main/docker-compose.yml) contains everything you need to get started with Suwayomi+PostgreSQL. Please be aware that PostgreSQL support is currently still in beta.
+
+**Note:** These settings are excluded from backups, so a backup can be used to easily switch database installations by setting up the connection first, then restoring the backup.

+## Overriding configuration options with command-line arguments
+You can override the above configuration options with command-line arguments. 
+You usually only need to set this when using custom setups like a portable version of Suwayomi or your if your User dir cannot be written to or your system administrator doesn't allow it.
+
+Use the pattern bellow.
+```
+java -Dsuwayomi.tachidesk.config.<configuration option 1>=<configuration value 1> -Dsuwayomi.tachidesk.config.<configuration option 2>=<configuration value 2> ... -Dsuwayomi.tachidesk.config.<configuration option N>=<configuration value N> -jar <path to server jar>
+```
+for example to force launching Suwayomi-Server in electron you would have something like:
+```
+java -Dsuwayomi.tachidesk.config.server.webUIInterface=electron -Dsuwayomi.tachidesk.config.server.electronPath="/path/to/electron" -jar Suwayomi-Server-v0.X.Y-rXXXX.jar
+```
+
+**Note:** you can put the command above in a custom launcher script like the ones found [here](https://github.com/Suwayomi/Suwayomi-Server/tree/master/scripts/resources).
+
+## Overriding Suwayomi-Server's Data Directory path
+The only possible way to override the default Data Directory path is with command-line arguments(the chicken and egg problem!).
+Add the special config option `server.rootDir="<path to data directory>"` to your command-line arguments.
+
+For example:
+```
+java -Dsuwayomi.tachidesk.config.server.rootDir="/path/to/data/directory" -jar Suwayomi-Server-v0.X.Y-rXXXX.jar

+Follow the steps below to create local manga.
+
+1. Place correctly structured manga inside the `local` directory located in [Suwayomi's data directory](https://github.com/Suwayomi/Suwayomi-Server/wiki/The-Data-Directory).
+1. You can then access the manga in the **Local source** source.
+
+If you add more chapters then you'll have to manually refresh the chapter list.
+
+Supported chapter formats are folder with pictures inside (such as `.jpg`, `.png`, etc.), `ZIP`/`CBZ`, `RAR`/`CBR` and `EPUB`. But expect better performance with directories and `ZIP`/`CBZ`.
+
+**Note:** While Suwayomi does support chapters compressed as **RAR** or **CBR**, note that **RAR** or **CBR** files using the **RAR5** format are not supported yet.
+
+**Note:** If **CBR** or **RAR** files do not work, you may need to extract and re-compress them into one of the supported formats.
+
+
+## Folder Structure
+
+Suwayomi requires a specific folder structure for local manga to be correctly processed. Local manga will be read from the `local` folder. Each manga must have a `Manga` folder and a `Chapter` folder. Images will then go into the chapter folder. See below for more information on archive files. You can refer to the following example:
+
+
+<div class="side-by-side">
+	<ul class="file-tree">
+		<li>
+			local/
+			<ul>
+				<li>
+					<span class="ft-icon ft-folder">Manga title/</span>

+		</li>
+	</ul>
+</div>
+
+**Note:** Chapter and page names should be ordered alphanumerically, using zero padded name prefixes is usually the best option.
+
+The path to the folder with images must contain both the manga title and the chapter name (as seen above).
+
+## Archive Files
+Archive files such as `ZIP`/`CBZ` are supported but the folder structure inside is not. Any folders inside the archive file are ignored. You must place the archive inside the `Manga` folder where the name will become the `Chapter` title. All images inside the archive regardless of folder structure will become pages for that chapter.
+
+<ul class="file-tree">

+## Advanced
+
+### Editing local manga details
+
+It is possible to add details to local manga. Like manga from other catalogs, you add information about the manga such as the author, artist, description, and genre tags.
+
+To import details along with your local manga, you have to create a json file. It can be named anything but it must be placed within the **Manga** folder. A standard file name is `details.json`. This file will contain the extended details about the manga in the `JSON` format. You can see the example below on how to build the file. Once the file is there, the app should load the data when you first open the manga, or you can pull down to refresh the details.
+
+You can copy the following example and edit the details as needed:
+``` json
+{
+	"title": "Example Title",
+	"author": "Example Author",
+	"artist": "Example Artist",
+	"description": "Example Description",
+	"genre": ["genre 1", "genre 2", "etc"],
+	"status": "0",
+	"_status values": ["0 = Unknown", "1 = Ongoing", "2 = Completed", "3 = Licensed"]
+}
+```
+
+### Using a custom cover image
+
+It is also possible to use a custom image as a cover for each local manga.
+
+To do this, you only need to place the image file, that needs to be named
+`cover.jpg`, in the root of the manga folder. The app will then use your
+custom image in the local source listing.

+## General Troubleshooting
+This guide will try to fix Suwayomi by reseting it to a clean installation state.
+
+- Make sure you have a recent backup of your library or create one in the app (if possible) because we **are going to wipe all Suwayomi data**.
+- Make sure Suwayomi is not running (right click on tray icon and quit or kill it through the way your Operating System provides)
+- Clear all browsing data on your browser if you use Suwayomi from a browser.
+- Delete the Suwayomi data directory located below and re-run the app.
+
+Note: Replace `<Account>` with the currently logged in account/username on your pc.
+
+On Mac OS X : `/Users/<Account>/Library/Application Support/Tachidesk`
+
+On Windows XP : `C:\Documents and Settings\<Account>\Application Data\Local Settings\Tachidesk`
+
+On Windows 7 and later : `C:\Users\<Account>\AppData\Local\Tachidesk`
+
+On Unix/Linux : `/home/<account>/.local/share/Tachidesk`
