From 39ae73b356a253036283b114855f8c5ddbb20f49 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 16 Oct 2018 09:05:47 -0400 Subject: file_sys/registered_cache: Use unique_ptr and regular pointers instead of shared_ptrs where applicable The data retrieved in these cases are ultimately chiefly owned by either the RegisteredCache instance itself, or the filesystem factories. Both these should live throughout the use of their contained data. If they don't, it should be considered an interface/design issue, and using shared_ptr instances here would mask that, as the data would always be prolonged after the main owner's lifetime ended. This makes the lifetime of the data explicit and makes it harder to accidentally create cyclic references. It also makes the interface slightly more flexible than the previous API, as a shared_ptr can be created from a unique_ptr, but not the other way around, so this allows for that use-case if it ever becomes necessary in some form. --- src/yuzu/game_list_worker.cpp | 19 +++++++++++-------- src/yuzu/game_list_worker.h | 2 +- 2 files changed, 12 insertions(+), 9 deletions(-) (limited to 'src/yuzu') diff --git a/src/yuzu/game_list_worker.cpp b/src/yuzu/game_list_worker.cpp index 8f99a1c78..3881aba5f 100644 --- a/src/yuzu/game_list_worker.cpp +++ b/src/yuzu/game_list_worker.cpp @@ -96,7 +96,7 @@ void GameListWorker::AddInstalledTitlesToGameList() { FileSys::ContentRecordType::Program); for (const auto& game : installed_games) { - const auto& file = cache->GetEntryUnparsed(game); + const auto file = cache->GetEntryUnparsed(game); std::unique_ptr loader = Loader::GetLoader(file); if (!loader) continue; @@ -107,7 +107,7 @@ void GameListWorker::AddInstalledTitlesToGameList() { loader->ReadProgramId(program_id); const FileSys::PatchManager patch{program_id}; - const auto& control = cache->GetEntry(game.title_id, FileSys::ContentRecordType::Control); + const auto control = cache->GetEntry(game.title_id, FileSys::ContentRecordType::Control); if (control != nullptr) GetMetadataFromControlNCA(patch, *control, icon, name); @@ -135,9 +135,10 @@ void GameListWorker::AddInstalledTitlesToGameList() { FileSys::ContentRecordType::Control); for (const auto& entry : control_data) { - const auto nca = cache->GetEntry(entry); - if (nca != nullptr) - nca_control_map.insert_or_assign(entry.title_id, nca); + auto nca = cache->GetEntry(entry); + if (nca != nullptr) { + nca_control_map.insert_or_assign(entry.title_id, std::move(nca)); + } } } @@ -153,9 +154,11 @@ void GameListWorker::FillControlMap(const std::string& dir_path) { QFileInfo file_info(physical_name.c_str()); if (!is_dir && file_info.suffix().toStdString() == "nca") { auto nca = - std::make_shared(vfs->OpenFile(physical_name, FileSys::Mode::Read)); - if (nca->GetType() == FileSys::NCAContentType::Control) - nca_control_map.insert_or_assign(nca->GetTitleId(), nca); + std::make_unique(vfs->OpenFile(physical_name, FileSys::Mode::Read)); + if (nca->GetType() == FileSys::NCAContentType::Control) { + const u64 title_id = nca->GetTitleId(); + nca_control_map.insert_or_assign(title_id, std::move(nca)); + } } return true; }; diff --git a/src/yuzu/game_list_worker.h b/src/yuzu/game_list_worker.h index 09d20c42f..0e42d0bde 100644 --- a/src/yuzu/game_list_worker.h +++ b/src/yuzu/game_list_worker.h @@ -63,7 +63,7 @@ private: void AddFstEntriesToGameList(const std::string& dir_path, unsigned int recursion = 0); std::shared_ptr vfs; - std::map> nca_control_map; + std::map> nca_control_map; QStringList watch_list; QString dir_path; bool deep_scan; -- cgit v1.2.3
