Warning

Esta PR ajusta o fluxo criado na #434. O fallback da DM de boas-vindas nunca postou nada, porque lia uma chave de config inexistente (channels.geral). Com a chave corrigida, cada membro novo com DM fechada gera um embed com menção no #geral. Isso pode causar um flood de mensagens no canal.

@danielhe4rt, você pode avaliar se o fallback deve continuar público no #geral?

Em produção, o WelcomeMember registrou este WARNING ao enviar a DM de boas-vindas:

O código 50278 não indica DM fechada (50007). Ele indica que o bot e o usuário não têm mais nenhum servidor em comum: o membro saiu, ou foi removido, antes do envio da DM.

O catch trata toda falha como DM fechada. Isso causa dois problemas:

  • O log grava o stack trace inteiro como WARNING, para um caso esperado.
  • O fallback no #geral nunca postou nada: o código lê bot-discord.channels.geral, uma chave que não existe no config. A chave certa é channels.general. Com a chave corrigida, o fallback marcaria no #geral um usuário que não está mais no servidor.

Alterações

  • Novo enum DiscordErrorCode (app-modules/bot-discord/src/Enums/) para os códigos de erro JSON da API do Discord: CannotSendMessagesToUser (50007) e NoMutualGuilds (50278). Ele implementa HasLabel, HasColor e HasDescription, com traduções en e pt_BR.
  • O bot-discord agora carrega traduções (lang/, namespace bot-discord).
  • WelcomeMember caiu de 203 para 65 linhas. Ele resolve o perfil e delega o resto:
    • Actions/Welcome/SendWelcomeDmAction: envia a DM, decide o fallback e registra o log.
    • Actions/Welcome/AnnounceNewMemberAction: os dois embeds do #auto-report.
    • Welcome/WelcomeEmbedBuilder: monta o embed uma vez; o fallback só troca a descrição e a menção.
    • DTO/WelcomeContextDTO: agrupa id, guild, username, avatar e ícone.
    • Concerns/ResolvesGuildIcon: o antigo static guildIconUrl() virou trait.
  • O canal do fallback é lido uma única vez, no construtor da Action. Antes eram duas leituras, com estilos diferentes.
  • O texto das mensagens saiu do código e foi para lang/{en,pt_BR}/welcome.php.
  • O processo do bot fixa o próprio locale (bot-discord.locale, padrão pt_BR). Sem isso ele herdaria APP_LOCALE=en e falaria inglês no servidor.
  • Bump de dependências do composer e do npm, e um argumento nomeado num teste do panel-admin (mudança do Rector).

Plano de Testes

  • vendor/bin/rector
  • vendor/bin/pint
  • vendor/bin/phpstan analyse
  • php artisan test --compact --parallel (1743 testes passando)
  • DiscordErrorCodeTest: valores dos códigos, conversão da exceção (código conhecido e desconhecido), traduções en e pt_BR
  • WelcomeEmbedBuilderTest: embed, botões, thumbnail ausente e o reenvio sem duplicar field ou botão
  • SendWelcomeDmActionTest: a regra do fallback para cada código e para um código desconhecido
  • ResolvesGuildIconTest: as quatro asserções do teste antigo, agora sobre o trait
  • BotLocaleTest: o padrão pt_BR, o locale aplicado no boot do bot e o copy nos dois idiomas

Issues Relacionadas

Discord code 50278 means the member left the guild, so the #geral mention reaches nobody.

Olá, @gvieira18!

Gostaria de entender a diferença entre o uso do config()->string('bot-discord.channels.general') e config('bot-discord.channels.general') que você fez em dois locais? Lançam exceptions diferentes?

Olá, @gvieira18!

Gostaria de entender a diferença entre o uso do config()->string('bot-discord.channels.general') e config('bot-discord.channels.general') que você fez em dois locais? Lançam exceptions diferentes?

TL;DR @hefeus

  • config('chave') = retorna mixed e não lança exception
  • config()->string('chave') = retorna o tipo do getter (->string) e lança uma exception caso não bata com o tipo

E tem varios tipos: ->integer(), ->boolean(), ->float() e ->array()
