Update Roadmap

Due to changes in the KOOK API, Bot users can no longer obtain all the necessary basic guild information at startup through the /guild/index API. Instead, it is now required to traverse each guild via the /guild/view API. This change can result in a significantly longer startup time and a large number of API requests for Bots that have joined many guilds. Therefore, the current version introduces the KookSocketConfig.StartupCacheFetchMode configuration item, which defines how the Bot loads the basic guild data needed at startup.

  • Synchronous: In synchronous mode, after obtaining a simple list of guilds at client startup, the client fetches the basic data of each guild through the API before triggering the Ready event.
  • Asynchronous: In asynchronous mode, after obtaining a simple list of guilds at client startup, the Ready event is triggered immediately, and a background task is started to fetch all the basic guild data.
  • Lazy: In lazy mode, after obtaining a simple list of guilds at client startup, the Ready event is triggered immediately without proactively fetching the basic guild data. When events involving the guild are received from the gateway, the guild's basic data will be fetched through the API if it has not already been obtained.
  • Auto: In automatic mode, the default setting, the client's startup mode is automatically determined based on the number of guilds the Bot has joined. If the number of guilds reaches LargeNumberOfGuildsThreshold (default is 50), it will be Lazy; if it reaches SmallNumberOfGuildsThreshold (default is 5), it will be Asynchronous; otherwise, it will be Synchronous. This determination is made each time the Bot connects to the WebSocket.

When not using Synchronous mode, after the Ready event, accessing cached guild entities might result in entities that do not fully contain basic guild data. The IsAvailable property indicates whether the guild entity has fully cached basic data through the API. In such cases, please proactively call the UpdateAsync method to update the cached guild entity through the API. The basic guild data mentioned above mainly includes the guild's channels, roles, channel permission overrides, and the current user's nickname within guilds.

The entire framework code has been updated to support nullable reference static analysis diagnostics. For the concept of nullable reference types in C#, please refer to Nullable reference types - C# | Microsoft Learn. After updating to the current version, all values that may be null will be marked as nullable types. This may cause some code to generate warnings during compilation, which should be treated as potential null reference exceptions and fixed accordingly.

Additionally, IQuote has a new implementation MessageReference, which only contains the ID of the message to be referenced and is used when calling the API in user code. Existing user code that creates Quote should migrate to MessageReference as soon as possible.

fileName has been renamed to filename; the event parameter Cacheable<SocketMessage, Guid> has been changed to Cacheable<IMessage, Guid>; SectionAccessoryMode.Unspecified is now replaced by null; Format.StripMarkDown has been renamed to StripMarkdown; and the filename parameter in the SendFileAsync overload that accepts the Stream type is now mandatory. Please note that these changes may cause compilation errors and should be fixed accordingly.

Additions

  • KookSocketConfig adds the StartupCacheFetchMode, LargeNumberOfGuildsThreshold, and SmallNumberOfGuildsThreshold configuration items to customize how the Bot's Socket client fetches the basic guild data needed at startup via the API.
  • Two new configuration properties AutoUpdateRolePositions and AutoUpdateChannelPositions have been added to KookSocketConfig, defaulting to false. When enabled, the client will automatically fetch data via the API upon receiving related events to maintain the cached role and channel sorting information.
  • Embed adds CardEmbed.
  • Card entities and builders now implement IEquatable<T>.
  • SocketSelfUser now implements IUpdateable.
  • Added IGuild.RecommendInfo.Certifications.
  • IQuote has a new implementation MessageReference, which only contains the ID of the message to be referenced and is used when calling the API in user code.
  • Support for the event types embeds_append, sort_channel, updated_server_type, batch_added_channel, batch_updated_channel, batch_deleted_channel, live_status_changed, PERSON typed updated_guild, add_guild_mute, delete_guild_mute, unread_count_changed has been added, but it is not yet confirmed whether these events will actually be dispatched.

Fixes

  • Fixed the issue where the author of private messages was incorrect.
  • Fixed the issue where SocketUserMessage.Quote.Author could be null.
  • Fixed the issue where Tags were missing corresponding values when referencing nonexistent entities in messages.
  • Fixed the issue where the voice client failed to handle undefined events, causing stream crashes.
  • Fixed the issue where parsing newly introduced mixed media messages failed.
  • Corrected the behavior of updating user nicknames.

Changes

  • Enabled nullable reference types feature. For the concept of nullable reference types in C#, please refer to Nullable reference types - C# | Microsoft Learn.
  • Various validations for the card builder are now deferred to the Build call.
  • The types of properties involving lists in cards have been changed to IList<T>.
  • Quote.Empty and its public constructor have been marked as Obsolete, and MessageReference should be used instead.
  • fileName has been renamed to filename.
  • The filename parameter in the SendFileAsync overload that accepts the Stream type is now mandatory.
  • BaseSocketClient._baseConfig has been renamed to BaseConfig.
  • The event parameter Cacheable<SocketMessage, Guid> has been changed to Cacheable<IMessage, Guid> to address the issue of entity download failure.
  • SectionAccessoryMode.Unspecified has been removed; please use null instead.
  • Format.StripMarkDown has been renamed to StripMarkdown, and the original method has been marked as Obsolete.
  • Format.StripMarkdown now removes hyphens -.

Others

  • Added a reference to PolySharp on .NET 7 and earlier target frameworks to support the implementation of some new features on older frameworks.
  • Added integration tests for some Socket events.
