Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

Change 3079316 on 2016/08/05 by Ben.Marsh
Better PCH selection in ShaderFormatOpenGL and MetalShaderFormat - make sure Core is the first included header.
Change 3080579 on 2016/08/08 by Ben.Marsh
Slate: Move DEBUG_TAB_MANAGEMENT into SDockingTabStack.h to remove circular include dependency with DockingPrivate.h.
Change 3080587 on 2016/08/08 by Ben.Marsh
StandaloneRenderer: Move platform includes into a separate header so we can make individual headers self-contained, without having a circular dependency on StandaloneRendererPrivate.h.
Change 3080789 on 2016/08/08 by Ben.Marsh
Move BuildGraph tasks for chunking, posting builds, labeling builds, and merging manifests into the MCP project. While we do provide public interfaces for this functionality, we don't currently expect anyone outside Epic to be using them.
Change 3080815 on 2016/08/08 by Ben.Marsh
BuildGraph: Add a -GenerateDocs option, which writes out an HTML file constructed from C# XML documentation containing all the task information.
Change 3081374 on 2016/08/08 by Ben.Marsh
UBT: Invalidate the makefile if any UHT headers are deleted. Should fix issue where files are moved from one module to another, and the original module no longer contains any generated headers. Its include path needs to be removed from the compile environment.
Change 3083152 on 2016/08/09 by Ben.Marsh
PR #2667: Add Intel C++ Compiler support to Windows build (Contributed by JeffRous)
Change 3084039 on 2016/08/10 by Ben.Marsh
BuildGraph: Add additional markup for parameter attributes. Also improve some documation.
Change 3084240 on 2016/08/10 by Ben.Marsh
Plugins: Allow plugins in the project folder to replace plugins in the engine folder with the same name. Prohibit multiple plugins with the same name at other times.
Change 3084337 on 2016/08/10 by Ben.Marsh
UBT: Specify the -precompile option when generating project files for a target, so we include all valid modules for intellisense.
Change 3085594 on 2016/08/11 by Ben.Marsh
Change modules which reference a public header for their PCH to use a private PCH instead, even if it just includes the public header for now.
Change 3085999 on 2016/08/11 by Ben.Marsh
Add some missing #pragma once directives.
Change 3086146 on 2016/08/11 by Ben.Marsh
Core: Move prototype and linkage specifier for ConsoleCommandLibrary_* functions into header matching cpp file.
Change 3086172 on 2016/08/11 by Ben.Marsh
Fixup some C-style header guards to use #pragma once instead.
Change 3087289 on 2016/08/12 by Ben.Marsh
Split out UPackage and UMetaData into their own headers (they're already implemented in separate CPP files)
Change 3087310 on 2016/08/12 by Ben.Marsh
Move method stubs for FNullSlateSoundDevice into a CPP file, since they're exported from the SlateCore module.
Change 3087341 on 2016/08/12 by Ben.Marsh
UdpMessaging: Move PCH before #if PLATFORM_DESKTOP; it will only be defined if the definition is included.
Change 3087457 on 2016/08/12 by Ben.Marsh
Core: Reorganize the FTransform and FMatrix headers: Transform.h now includes TransformNonVectorized.h or TransformVectorized.h as appropriate, and UnrealMatrix.h is now Matrix.inl (and included from Matrix.h).
Change 3088407 on 2016/08/13 by Ben.Marsh
Replace use of Windows SIZE_T define with the regular C++ size_t.
Change 3088416 on 2016/08/13 by Ben.Marsh
Include a header from all .generated.cpp files (GeneratedCppIncludes.h) which includes all the basic types required to compile them, rather than assuming that the module PCH will include everything.
Also include the real declarations of noexport classes in Object.h (now renamed to NoExportTypes.h for clarity) when the CPP macro is defined, so the .generated.deps.h file will automatically have the correct definitions for them at compile time rather than relying on them being in the private PCH.
Finally, rename UObject.h to Object.h for consistency with the naming convention for all other UObject classes. UObject.h still exists for now, but outputs a deprecated message if included.
Change 3088544 on 2016/08/14 by Ben.Marsh
Core: Move the definition of the TEXT() macro into Platform.h, to avoid having to include OS headers to get it.
Change 3088552 on 2016/08/14 by Ben.Marsh
Fix compile errors for some modules that don't already include CoreUObject.h.
Change 3088925 on 2016/08/15 by Ben.Marsh
Remove circular include dependencies from VulkanRHI.
Change 3088926 on 2016/08/15 by Ben.Marsh
Remove duplicate definition for WITH_FIXED_AREA_ENTERING_COST from EngineDefines.h - always uses the definition from DetourNavMeshQuery.h instead.
Change 3088930 on 2016/08/15 by Ben.Marsh
Remove circular include dependency from PhysX.
Change 3088935 on 2016/08/15 by Ben.Marsh
OnlineSubsystemUtils: Move CPP files out of public header directory.
Change 3088965 on 2016/08/15 by Ben.Marsh
Add private PCH to Landscape, MoviePlayer, TaskGraph, XAudio2 and RealtimeProfiler modules.
Change 3088966 on 2016/08/15 by Ben.Marsh
Engine: Move CPP files out of public header directories.
Change 3089520 on 2016/08/15 by Ben.Marsh
BuildGraph: Change documentation command to output markdown.
Change 3090299 on 2016/08/16 by Ben.Marsh
D3D12RHI: Move around some implementations to fix circular header dependencies which are masked by delayed template instantiation.
Change 3090303 on 2016/08/16 by Ben.Marsh
Engine: Add a template specialization for TPointerIsConvertibleFromTo<AActor, const volatile UObject> to fix dependency on complete AActor definition for static assert in TWeakPointer<AActor>, which only appears if including Level.h without Actor.h. Delayed template instantiation usually masks this issue.
Change 3091861 on 2016/08/17 by Ben.Marsh
Remove circular header dependencies, and fix ambiguous include paths in OSVR.
Change 3092068 on 2016/08/17 by Ben.Marsh
Moving VulkanDynamicRHI into its own header.
Change 3093133 on 2016/08/18 by Ben.Marsh
EC: Include additional context lines for Clang errors.
Change 3093147 on 2016/08/18 by Ben.Marsh

Change 2860430 on 2016/02/09 by Aaron.McLeran
UE-26216 EQ Settings are incorrect, unable to produce a LPF setting
- Fix is to expose the xaudio2 eq effect parameters actually used
- Added support for real-time previewing of EQ parameter changes (interpolates from current to new values)
Platform code:
- CoreAudio's EQ AU effects have identical settings as well, translated the params to the mac code
- PS4 code was disabled before -- this change is a first-pass implementation for PS4, but its still not enabled
Change 2867932 on 2016/02/15 by Aaron.McLeran
Some adjustments and cleanups to recent dev-framework features
- Removing change to ObjectVersion in favor of a TaggedPropertyRedirect in BaseEngine.ini for EQSettings variables
- Adding bIsTraceDelegateBound bool for flagging need to add delegate binding for async traces
- Reverse iteratoing through PendingSoundsToDelete for deferred delete for async occlusion checks and using RemoveAtAtSwap
