From 4acec5283eec3b1a1714981669b605b93910b700 Mon Sep 17 00:00:00 2001 From: Morph <39850852+Morph1984@users.noreply.github.com> Date: Tue, 28 Sep 2021 20:53:28 -0400 Subject: [PATCH] service: bcat: Remove BoxCat BCAT implementation The current implementation of BoxCat as it stands is non-functional due to the reliance on a server providing BCAT files. This implementation will eventually be replaced with one that allows the use of local BCAT files dumped from a Nintendo Switch. --- src/core/CMakeLists.txt | 12 - src/core/hle/service/bcat/backend/boxcat.cpp | 548 ------------------- src/core/hle/service/bcat/backend/boxcat.h | 64 --- src/core/hle/service/bcat/bcat_module.cpp | 7 - 4 files changed, 631 deletions(-) delete mode 100644 src/core/hle/service/bcat/backend/boxcat.cpp delete mode 100644 src/core/hle/service/bcat/backend/boxcat.h diff --git a/src/core/CMakeLists.txt b/src/core/CMakeLists.txt index a59c5a552..aa3b26628 100644 --- a/src/core/CMakeLists.txt +++ b/src/core/CMakeLists.txt @@ -651,13 +651,6 @@ add_library(core STATIC tools/freezer.h ) -if (YUZU_ENABLE_BOXCAT) - target_sources(core PRIVATE - hle/service/bcat/backend/boxcat.cpp - hle/service/bcat/backend/boxcat.h - ) -endif() - if (MSVC) target_compile_options(core PRIVATE /we4242 # 'identifier': conversion from 'type1' to 'type2', possible loss of data @@ -690,11 +683,6 @@ create_target_directory_groups(core) target_link_libraries(core PUBLIC common PRIVATE audio_core video_core) target_link_libraries(core PUBLIC Boost::boost PRIVATE fmt::fmt nlohmann_json::nlohmann_json mbedtls Opus::Opus) -if (YUZU_ENABLE_BOXCAT) - target_compile_definitions(core PRIVATE -DYUZU_ENABLE_BOXCAT) - target_link_libraries(core PRIVATE httplib nlohmann_json::nlohmann_json) -endif() - if (ENABLE_WEB_SERVICE) target_compile_definitions(core PRIVATE -DENABLE_WEB_SERVICE) target_link_libraries(core PRIVATE web_service) diff --git a/src/core/hle/service/bcat/backend/boxcat.cpp b/src/core/hle/service/bcat/backend/boxcat.cpp deleted file mode 100644 index 7ca7f2aac..000000000 --- a/src/core/hle/service/bcat/backend/boxcat.cpp +++ /dev/null @@ -1,548 +0,0 @@ -// Copyright 2019 yuzu emulator team -// Licensed under GPLv2 or any later version -// Refer to the license.txt file included. - -#include - -#ifdef __GNUC__ -#pragma GCC diagnostic push -#pragma GCC diagnostic ignored "-Wshadow" -#ifndef __clang__ -#pragma GCC diagnostic ignored "-Wmaybe-uninitialized" -#endif -#endif -#include -#include -#include -#ifdef __GNUC__ -#pragma GCC diagnostic pop -#endif - -#include "common/fs/file.h" -#include "common/fs/fs.h" -#include "common/fs/path_util.h" -#include "common/hex_util.h" -#include "common/logging/log.h" -#include "common/settings.h" -#include "core/core.h" -#include "core/file_sys/vfs.h" -#include "core/file_sys/vfs_libzip.h" -#include "core/file_sys/vfs_vector.h" -#include "core/frontend/applets/error.h" -#include "core/hle/service/am/applets/applets.h" -#include "core/hle/service/bcat/backend/boxcat.h" - -namespace Service::BCAT { -namespace { - -// Prevents conflicts with windows macro called CreateFile -FileSys::VirtualFile VfsCreateFileWrap(FileSys::VirtualDir dir, std::string_view name) { - return dir->CreateFile(name); -} - -// Prevents conflicts with windows macro called DeleteFile -bool VfsDeleteFileWrap(FileSys::VirtualDir dir, std::string_view name) { - return dir->DeleteFile(name); -} - -constexpr ResultCode ERROR_GENERAL_BCAT_FAILURE{ErrorModule::BCAT, 1}; - -constexpr char BOXCAT_HOSTNAME[] = "api.yuzu-emu.org"; - -// Formatted using fmt with arg[0] = hex title id -constexpr char BOXCAT_PATHNAME_DATA[] = "/game-assets/{:016X}/boxcat"; -constexpr char BOXCAT_PATHNAME_LAUNCHPARAM[] = "/game-assets/{:016X}/launchparam"; - -constexpr char BOXCAT_PATHNAME_EVENTS[] = "/game-assets/boxcat/events"; - -constexpr char BOXCAT_API_VERSION[] = "1"; -constexpr char BOXCAT_CLIENT_TYPE[] = "yuzu"; - -// HTTP status codes for Boxcat -enum class ResponseStatus { - Ok = 200, ///< Operation completed successfully. - BadClientVersion = 301, ///< The Boxcat-Client-Version doesn't match the server. - NoUpdate = 304, ///< The digest provided would match the new data, no need to update. - NoMatchTitleId = 404, ///< The title ID provided doesn't have a boxcat implementation. - NoMatchBuildId = 406, ///< The build ID provided is blacklisted (potentially because of format - ///< issues or whatnot) and has no data. -}; - -enum class DownloadResult { - Success = 0, - NoResponse, - GeneralWebError, - NoMatchTitleId, - NoMatchBuildId, - InvalidContentType, - GeneralFSError, - BadClientVersion, -}; - -constexpr std::array DOWNLOAD_RESULT_LOG_MESSAGES{ - "Success", - "There was no response from the server.", - "There was a general web error code returned from the server.", - "The title ID of the current game doesn't have a boxcat implementation.
