Scheduled events and huge event dispatching optimization

Breaking Changes

• hikari.config has now been split up to hikari.api.config and hikari.impl.config to avoid leaking impl detail.
  This also means that config types are no-longer accessible at the top level (directly on hikari). (#1067)
• Hide the entity factory's component deserialize methods. (#1074)
• Remove nonce parameter from create message.
  This was purposely removed from the bot api documentation inferring that its no-longer officially supported. (#1075)
• Remove VoiceRegion.is_vip due to Discord no longer sending it. (#1086)
• Remove store sku related application fields and store channels. (#1092)

Deprecation

• Renamed nick argument to nickname for edit member and add user to guild REST methods. (#1095)

Features

• Scheduled event support. (#1056)
• get_guild() is now available on hikari.GuildChannel. (#1057)
• Optimize receiving websocket JSON for the happy path. (#1058)
• The threaded file reader now persists the open file pointer while the context manager is active. (#1073)
• Optimize event dispatching by only deserializing events when they are needed. (#1094)
• Add hikari.locales.Locale to help with Discord locale strings. (#1090)

Bugfixes

• fetch_my_guilds no-longer returns duplicate guilds nor makes unnecessary (duplicated) requests when newest_first is set to True. (#1059)
• Add InviteEvent to hikari.events.channel_events.__all__, hikari.events.__all__ and hikari.__all__. (#1065)
• Fix incorrect type for ATTACHMENT option values. (#1066)
• EventManager.get_listeners now correctly defines polymorphic and returns accordingly. (#1094)
• Take the major param for webhook without token endpoints when handling bucket ratelimits. (#1102)
• Fix incorrect value for GuildFeature.MORE_STICKERS. (#1989)

Cleanups and bugfixing

Features

• Added a total_length function to hikari.embeds.Embed
  • Takes into account the character length of the embed's title, description, fields (all field names and values), footer, and author combined.
  • Useful for determining if the embed exceeds Discord's 6000 character limit. (#796)
• Added attachment command option type support. (#1015)
• Add MESSAGE_CONTENT intent. (#1021)
• Custom substitutions can now be used in hikari.internal.ux.print_banner. (#1022)
• get_guild() is now available on hikari.Member. (#1025)
• The notorious "failed to communicate with server" log message is now a warning rather than an error. (#1041)
• hikari.applications, hikari.files, hikari.snowflakes and hikari.undefined are now all explicitly exported by hikari.__init__, allowing pyright to see them without a direct import. (#1042)

Bugfixes

• Fix bucket lock not being released on errors while being acquired, which locked the bucket infinitely (#841)

• enable_signal_handlers now only defaults to True when the run/start method is called in the main thread.
  This avoids these functions from always raising when being run in a threaded environment as only the main thread can register signal handlers. (#998)

• Sub-command options are now properly deserialized in the autocomplete flow to AutocompleteInteractionOption instead of CommandInteractionOption. (#1012)

• Attempt to reconnect on a gateway TimeoutError. (#1014)

• Properly close GatewayBot when not fully started. (#1023)

• The async context manager returned by File.stream now errors on enter if the target file doesn't exist to improve error handling when a file that doesn't exist is sent as an attachment.

  The multiprocessing file reader strategy now expands user relative (~) links (like the threaded strategy). (#1046)

Context menus and switch to PyNacl for interaction server

Breaking Changes

• Running the standard interaction server implementation now requires a hikari[server] install.

  This matches a switch over to PyNacl for the cryptographic payload validation. (#986)

Deprecation

• Deprecated RESTClient.command_builder and RESTClient.create_application_command.

  You should switch to RESTClient.slash_command_builderand RESTClient.create_slash_command respectively. (#924)

Features

• Added support for GET /users/@me/guilds/{guild}/member. (#955)

• Add the SUPPRESS_USER_JOIN_REPLIES system channel flag. (#957)

• Add new message content intent related application flags. (#958)

• Add the BOT_HTTP_INTERACTIONS user flag. (#959)

• Add new presence activity flags. (#960)

• Add URL methods and properties for rich presence assets. (#961)

• Add locale and guild_locale properties to interactions. (#962)

• Add ability to send attachments in an interaction initial response. (#971)

• Add display_avatar_url property to hikari.Member and hikari.User. (#975)

• old_x keyword arguments in the event factory now default to None. (#984)

• Strip tokens in the standard bot impls and RESTApp.

  This helps avoids a common mistake with trailing new-lines which leads to confusing errors on request. (#989)

Bugfixes

• Relaxed typing of methods with union entry specific specialisations through overloads. (#876)
• Fix deprecation warnings raised by usage of asyncio.gather outside of an active event loop in GatewayBot.run. (#954)
• UTF-8 characters are now properly handled for audit-log reasons in REST requests. (#963)
• Fix magic methods for UserImpl and its subclasses. (#982)

• Implement member timeouts
  • Add raw_communication_disabled_until and communication_disabled_until to Member

  • Add communication_disabled_until attribute to edit_member (#940)

Bugfixes

• Improved pyright compatibility and introduced pyright "type-completeness" checking. (#916)
• Add EventStream.filter specialisation to the abc. (#917)
• Update the app command name regex to account for more recently documented support for non-english characters on Discord's end. (#918)

• Guild.is_nsfw has been replaced with Guild.nsfw_level

  • This was removed due to a new unicode version breaking the emojis in old versions of Python and Discord not providing any standardization regarding emojis accepted by the API (discord/discord-api-docs#2782). In light of this, we have also removed Emoji.unicode_names as it is not guaranteed to not error

  • This includes moving the attribute in the objects too
