Raw Blame History

// test_chat_join.c — компонентные + интеграционные тесты join-протокола.
//
// Задача 1 (компонентные): криптография дерева приглашений (build_sign_msg / sign_pubkey /
// verify_signature), сериализация мембера, chat_join_process_request (инвайтер), хранилище
// ключей (register_key self / lookup_inviter), member_sync_validate_pubkey.
//
// Задача 2 (интеграция): два инстанса A(инвайтер) и C(connection) — регистрация join-ключа
// через etcp_router, после сходимости BGP lookup_inviter(C) == A.node_id.
//
// chat_core/chat_sync (глобальные синглтоны) НЕ используются: конфиг без секции [chatserver],
// member_sync/chat_join инициализируются вручную.
