Moved construction logic to separate method, and call that from constructor instead. When willing to change the entire context on the same object, you can now just call 'InitFromXXXX()'. Previously, a whole new object would be generated and copied into ours, and then deleted again.
It was still crashing as the thisptr should actually be passed into the alloc callback. Changed and the function call is now identical to engine's impl. Tested in Debug, Profile and Release, Release has also been tested with LTCG.
Crash occurred as the arguments to the alloc/free callbacks would involve the 'this' pointer, and therefore, the registers would shift and misalign. The fix is to just make the functions static and call the pointers directly from the singleton exposed by the engine. Additional cleanup has been performed by adding typedefs for the function pointers.
Remove the option to disable dynamic init, it was broken anyways as the string was getting constructed, and therefore, dynamic memory could be allocated if string exceeds a certain size where it has to be moved from stack to heap. The only functions we were interested in, while not allocating anything have been made static instead in the last refactor round.
- Set character set to multi-byte (this is because the game is also build with it).
- Utility function 'FileExists' now takes a raw string pointer, this avoids having to construct a fs::path each time its getting called (which is quite a lot!).
- Performed overall cleanup to code containing logic to override load paths. Mostly removing unnecessary copy constructions.
The game's memalloc does not support memory expansion, the base expansion function couldn't be shadowed properly without linker errors. However we want to make sure no instances of it get compiled into the module, ever. Therefore, the duplicate symbol is kept in memoverride (_expand_base), and the only usage has been removed from LZHAM's 'lzham_mem'. If a linkage is attempted to anything utilizing '_expand', a linker error will be emitted and no image will be generated.
Find regex pattern:
inline auto ([a-zA-Z0-9_]+) = ([a-zA-Z0-9_]+)\.RCast<([a-zA-Z0-9_:<>*]+) *\(\*\)\(([^)]*)\)>\(\);
Replace regex pattern:
inline $3(*$1)($4);
This commit also removes the unnecessary initialization (which was required to type the auto variables),
and therefore removed 6kb of unnecessary dynamic initialization code.
* Added and utilized auto lock/unlock mechanism.
* Rebuild CThreadFastMutex's 'Lock' and 'Unlock' methods in the SDK.
* Forced thread intrinsics and ID checkers as inline.
Moved CModule statics to a separate translation unit, preventing the linker to link unused stuff into the loader module, thus allowing us to drop the linkage of unused libraries.
Don't recreate it in the engine (LauncherMain) if its already created in the SDK. This solution toggles a hybrid between creating it in the SDK, or in the engine when -noworkerdll is passed to the loader.
* Override debug malloc functions, doesn't seem to be properly supported by the visual studio libraries, but it has to be done, else we crash trying to initialize the DLL (must use the same allocator as the game), a linker flag '/FORCE:MULTIPLE' had to be set to make this work, this should be set for only DEBUG builds in the future!.
* Fixed a bug in '_recalloc_base' where the allocation size was not calculated properly. Only the size was taken into account, but it should had been multiplied by the count.
* Stubbed additional CRT debug only memory debugging code, it will crash on our implementation in debug.
Else everything linked against tier0 will have to use the game's memalloc implementation, which requires it to run with the game process. Only limit this to DLL's that run with the game process.
This covers the entire source code, including thirdparty libraries if memstd.cpp is compiled.
Things left to be done:
- Utilize the debug methods of the CStdMemAlloc class by routing the debug variants to those.
- Move this to a standalone library, so tools and stuff not interfacing directly with the game engine can still link against tier0.
Added recalloc. _expand should be replaced as well in the nearby future. The functions should override the _xxxx_base variants instead, and be moved to a separate lib to cover the executable globally.
Global 'direct' usage of 'MemAllocSingleton()' has been jettisoned. Where possible, smart pointers were used instead. During the refactor, the following bugs were addressed and fixed:
- The virtual destructor of 'CCVarIteratorInternal' was NOT called on destruction.
- Class function 'KeyValues::MakeCopy' did NOT calculate the buffer size of the wide string correctly, the original calculation was 'len+1*sizeof(wchar_t)', but should've been '(len+1)*sizeof(wchar_t)'.
Some other code changes include:
- Tier0 include 'memstd.h' has been moved above all thirdparty includes, to make sure the memalloc functions get shadowed with ours in third party libraries as well.
- RPak file paths string literals are now defines.
- 'DestroyOverlay' has been refactored to match the assembly of the game.
This commit replaces the standard memalloc system with that of the game. This means we can share the same allocated memory objects between the game and SDK without having to use 'MemAllocSingleton()' and manually call the constructors/destructors. This also means we can create ConVar's and ConCommands in the global scope, and a bunch more cool stuff. The explanation in 'r5dev\loader\loader.cpp' documents the new loading system.
*Use unordered_map to get mpdule sections instead, as this is more performant than comparing strings.
* Removed 'm_SectionName' field from ModuleSections_t, as the unordered map now keeps track of them.
* Removed all extraneous module section copies.
* Renamed 'GetImportedFunction' to 'GetImportedSymbol'.
* Renamed 'GetExportedFunction' to 'GetExportedSymbol'.
*Made a static version of 'GetImportedSymbol' and 'GetExportedSymbol', so it could be used on raw module base addresses.
*Created inlines for getting the DOS and NT headers.
*Improved formatting so the code could be read more easily on a vertical monitor.
This occurs when the game's unhandled exception handler is getting called after ours. both will create a crashmsg process. This happened as CCrashHandler::End() was called before the in-game exception filter was fired, and therefore CCrashHandler::Handled would return false, and this fire the in-game exception filter. This commit removes the additional check, we just use our vectored exception handler entirely over the game's one, as this one captures everything an unhandled exception handler will capture, and more. The 'Handled' function/fields in CCrashHandler have been renamed to 'Handling', as this is a more appropriate name.
Only display hex comment on decimal ALU register if its above 9, and format it as such that it fits perfectly next to a register that is equal or lower than one million. Added additional comments.
Required for overriding memalloc callbacks in libraries to feature the game's implementation instead. Named using the 'R_' prefix, as the 'V_' versions were already used.
Previously, it was all controlled from the global init (applied to all projects), but some projects need different options. With these changes, you can disable the common options applied in the 'add_module' macro, and set your own if desired.
This commit significantly reduces output code size, and a noticeable increase in performance. Changes are:
- Removed all extraneous std::string and std::vector copy constructions; use raw pointers instead to boost performance.
- Marked simple getters in CModule inline.
- Marked several functions in CModule const.
- Slightly reordered CModule class.
- 'CMemory::CheckOpCodes' and 'CMemory::Patch' now take a const reference.
Properly fix the aligned memalloc singleton in the SDK; the implementation now uses a callback based approach for calling the allocator and deallocator.
Added all public headers to CMake projects, also moved some files around in the public directory. Translation units have been moved to the libraries that were responsible for implementing them, as this game is monolithic.
Treat them as errors globally. Most of the time a warning is a bug, or problem in code that could be solved in a different (better) manner. Thirdparty code have this disabled. The warnings as errors option can be globally disabled through the CMake GUI, but this is not recommended.
Use the 'add_module' macro to add modules without creating duplicate code. This macro also takes a reuse PCH as parameter, so modules that need a precompiled header, could reuse those from different targets that compile them. This commit also restructures the group order of the generated solution files for easier code navigation.
* All libraries have been isolated from each other, and build into separate artifacts.
* Project has been restructured to support isolating libraries.
* CCrashHandler now calls a callback on crash (setup from core/dllmain.cpp, this can be setup in any way for any project. This callback is getting called when the apllication crashes. Useful for flushing buffers before closing handles to logging files for example).
* Tier0 'CoreMsgV' function now calls a callback sink, which could be set by the user (currently setup to the SDK's internal logger in core/dllmain.cpp).
TODO:
* Add a batch file to autogenerate all projects.
* Add support for dedicated server.
* Add support for client dll.
Bugs:
* Game crashes on the title screen after the UI script compiler has finished (root cause unknown).
* Curl error messages are getting logged twice for the dedicated server due to the removal of all "DEDICATED" preprocessor directives to support isolating projects. This has to be fixed properly!
