From be9eb30fd0079cd81ce1cd8e131b309e56ebd0e2 Mon Sep 17 00:00:00 2001 From: Alexander Freeman Date: Mon, 14 Apr 2025 16:15:25 +0300 Subject: [PATCH] Fix ImGui assert: ensure null-terminated buffer with +1 Fix host debugger crash when no debugger is attached Added safe break implementation: replaced unsafe __debugbreak() with a guarded check using IsDebuggerPresent(). Prevents crashes when triggering host debugger without an active debugger attached. Fix host debugger crash when no debugger is attached Added safe break implementation: replaced unsafe __debugbreak() with a guarded check using IsDebuggerPresent(). Prevents crashes when triggering host debugger without an active debugger attached. [Logging]Disable logging in Release via XE_OPTION_ENABLE_LOGGING=0 [hybrid mode] Implement hybrid logging system (XE_OPTION_ENABLE_LOGGING): - Disables all log macros and sinks in release mode - Keeps interface & headers safe for use - Prevents xenia.log creation in Release - Improves performance on Steam Deck (~+10% CPU) x+Logging] Improve ImGui safety & disable logging in Release - Fixed ImGui assert: ensure null-terminated buffer (+1 size) - Safe fallback for __debugbreak() when no debugger is attached - Implemented hybrid logging system (XE_OPTION_ENABLE_LOGGING): - Disables all XELOG macros and sinks in release mode - Keeps interface & headers safe for use - Prevents xenia.log creation in release - Improves performance on Steam Deck (~+10% CPU) --- premake5.lua | 7 +++- src/xenia/app/emulator_window.cc | 2 +- src/xenia/base/debugging.h | 3 ++ src/xenia/base/debugging_win.cc | 14 ++++++- src/xenia/base/logging.cc | 40 +++++++++++++++++--- src/xenia/base/logging.h | 17 +++++++-- src/xenia/cpu/backend/x64/x64_emitter.cc | 15 ++++++-- src/xenia/gpu/d3d12/d3d12_graphics_system.cc | 2 +- src/xenia/gpu/shader_translator.cc | 7 +++- src/xenia/gpu/shader_translator.h | 29 +++++++++----- src/xenia/ui/d3d12/d3d12_provider.cc | 2 +- src/xenia/ui/d3d12/d3d12_provider.h | 2 +- src/xenia/ui/imgui_dialog.cc | 8 +++- 13 files changed, 116 insertions(+), 32 deletions(-) diff --git a/premake5.lua b/premake5.lua index 323ca622e..ad5017b18 100644 --- a/premake5.lua +++ b/premake5.lua @@ -79,11 +79,16 @@ filter({"configurations:Debug", "platforms:Linux"}) "_GLIBCXX_DEBUG", -- make dbg symbols work on some distros }) -filter("configurations:Release") + filter("configurations:Release") runtime("Release") defines({ "NDEBUG", "_NO_DEBUG_HEAP=1", + -- AlexFreeman -> отключаем всё лишнее в Release-сборке + "XENIA_DISABLE_LOGGING", + "XENIA_ENABLE_TRACING=0", + "XENIA_ENABLE_ASSERTIONS=0", + "XE_OPTION_ENABLE_LOGGING=0" }) optimize("Speed") inlining("Auto") diff --git a/src/xenia/app/emulator_window.cc b/src/xenia/app/emulator_window.cc index 46558d25f..e115be314 100644 --- a/src/xenia/app/emulator_window.cc +++ b/src/xenia/app/emulator_window.cc @@ -2072,7 +2072,7 @@ void EmulatorWindow::LoadRecentlyLaunchedTitles() { toml::parse_result parsed_file; try { parsed_file = toml::parse(file); - } catch (toml::parse_error& exception) { + } catch (toml::parse_error& exception [[maybe_unused]]) { XELOGE("Cannot parse file: recent.toml.
