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 2986511 on 2016/05/23 by Ben.Marsh
UdpMessaging: Force references to symbols in the files containing UDP automated tests. Since plugins are compiled into static libraries before being linked into the executable, the linker will exclude any object files which don't have any referenced symbols. In non-unity builds, or adaptive unity builds with modified test files, this results in the tests not being linked in.
Change 2993274 on 2016/05/27 by Ben.Marsh
Fix UGS enumerating deleted .target.cs files when trying to detect editor target name.
Change 2994265 on 2016/05/31 by Ben.Marsh
Add info about setting up CIS integration and zipped editor builds in UGS.

PR #2443: [Unreal Game Sync] Added -project so shortcut or script can hint at the project file to open. (Contributed by paulevans)
Change 2994287 on 2016/05/31 by Ben.Marsh
UnrealGameSync: Add information about how UGS self-patches and updates.
Change 2996928 on 2016/06/01 by Ben.Marsh
UnrealGameSync: Fix trying to sync files which are open for branch or move/add. They don't exist on the server yet.
Change 2997619 on 2016/06/02 by Ben.Marsh
UAT: Fix PRX files not being remapped on PS4. All non-UFS should be allowed to be remapped, and UFS files can be if we're not using a PAK file.
Change 2999769 on 2016/06/03 by Ben.Marsh
UBT: Fix codepaths which assume that the current user account has a personal folder. The SYSTEM account (which Jenkins defaults to using) does not.
Change 3004879 on 2016/06/07 by Ben.Marsh
Remove copy of AWSSDK in NotForLicensees folder.
Change 3004902 on 2016/06/07 by Ben.Marsh
UAT: Switch MCP to use version of AWSSDK that's not in a NotForLicensees folder.

Add the GitHub promotion to the UE4 binary release build.

Change 3017694 on 2016/06/17 by Ben.Marsh
EC: Produce an error if trying to sync back to a changelist more than 30 days before the most recent change. Meant to catch errors in entered CL fields from the dashboard. Can be overridden by specifying --allow-old-change in the build arguments.
Change 3017695 on 2016/06/17 by Ben.Marsh
UBT: Use a well defined order for parsing configuration files, rather than ignoring one file if another has a newer timestamp. Prevents confusing behavior where settings can be present, but are completely ignored. Now prioritizes the BuildConfiguration.xml file in the My Documents/Unreal Engine/UnrealBuildTool, followed by the one in AppData/Roaming/Unreal Engine/UnrealBuildTool. Both are added to the Config section of the solution if present, under different folders.

Change 3017698 on 2016/06/17 by Ben.Marsh
Rename the <MsBuild> task to <CsCompile>, highlighting the fact that it only actually works on .csproj files (and not .sln files or other project types).
#jira UEB-664
Change 3017701 on 2016/06/17 by Ben.Marsh
BuildGraph: Relax a lot of the restrictions relating to using output tags from nodes. Output tags may contain an arbitrary set of files, including files which are also in other tags or produced by other nodes, but will not be written to temp storage more than once. The default tagged set of files for a node (eg. #MyNodeName) now includes all build products produced by that node.
Temp storage now separates the storing of build products from the tags which reference them. A TempStorageFileList object is written for each output tag, which includes a list of files as well as a list of the storage blocks referenced by it. When a node depends on a tag, the TempStorageFileList is read first and used to determine which storage blocks to read.
All tasks now have overloaded functions for returning the tags which they modify and/or reference, and errors are produced if an existing tag is modified, or referenced without being added as an input dependency.
Change 3017714 on 2016/06/17 by Ben.Marsh
BuildGraph: Allow specifying multiple tag names in the 'Tag' attribute of build tasks (or 'With' attribute of the 'Tag' task).
Change 3018007 on 2016/06/17 by Ben.Marsh
UBT: Add sections to the target receipt listing files which are required to build using precompiled binaries (as previously generated using -generateexternalfilelist), and runtime dependencies that may be required when using precompiled binaries but aren't actually required for the current target (which previously had to be specified through InstalledEngineFilters.ini). Tested by running UBT with arguments "UE4Game Win64 Development -precompile -xgeexport" and examining target receipt.

Fix compilation of FreeType on Clang for Windows - there's an fttypes.h header already in the Windows SDK, so use a relative include path instead.

UBT: Fix strings not being escaped before writing to JSON files.
Change 3020378 on 2016/06/20 by Ben.Marsh
UBT: Exclude precompiled files from the target receipt which are outside the engine and project directories. We don't need SDK libs being added to the precompile list.
Change 3020966 on 2016/06/21 by Ben.Marsh
EC: Allow scheduling builds at a certain offset past midnight, using the schedule formatted like "Every 20m from 04:00", and add scheduled builds of target platforms for dev streams every 4 hours. Also make the meaning of "Editor Only" and "Editor, Tools & Monolithics" build names consistent between Dev streams and Main, and add a new "Editor, Tools, Monolithics & DDC" build type includes additional DDC build for //UE4/Main.

UETOOL-213 - Minimize Slate FString -> FText conversion (remove SLATE_TEXT_ATTRIBUTE)
This fixes any editor/engine specific code that was passing text to Slate as FString rather than FText.
[CL 2399803 by Jamie Dale in Main branch]
* Moved Slate.h into SlateBasics.h and began shifting less commonly used headers into SlateExtras.h.
* Slate.h now simply includes SlateBasics.h and SlateExtras.h.
* Slate.h includes a deprecated warning now to indicate that SlateBasics.h + specific includes should be used instead.
* Moved dozens of inlined functions using Slate widgets into .cpp files to avoid header dependencies.
* All code samples now include SlateBasics.h and SlateExtras.h so future shifts will not break most those projects, but not trigger the deprecation warning of including Slate.h.
