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.

Pak signing changes
- Integrated into EDL loader
- Changed to not encrypt each CRC in the sig file, rather just store a single encryped signature of the entire sig file. Removes need to decrypt thousands of signatures at startup.

Minor change in the condition that detects the same hangs - allow the same callstacks from different threads
Change 3193168 on 2016/11/10 by Steve.Robb
TSparseArray now reserves space in reverse so that new elements get added to the front of the allocation rather than the back, which is better for memory traversal and meets expectations more closely.
Change 3193171 on 2016/11/10 by Steve.Robb
Easier debugging of FPendingRegistrantInfo map.
Change 3193188 on 2016/11/10 by Steve.Robb

Added improved logging to Slack with option to monitor MDD performance
Added hourly log folders to MDD logs
Added support for types of crashes we don't want to symbolicate (using it to skip callstack gen for hang detected ensures)
Change 3200382 on 2016/11/16 by Robert.Manuszewski
Async Loading code will now detach the linker when resetting async package loader to avoid situations when loading the same asset multiple times results in the following load request finding the old linker after the package has been loading but the async package hasn't been deleted yet (async package for the old request in limbo state but linker exists).
Change 3200562 on 2016/11/16 by Gil.Gribb
UE4 - Fixed rare issue with reloading nativized blueprints with the EDL and a minor simplication.
Change 3201093 on 2016/11/16 by Ben.Zeigler
#UE 38654 Fix EDL cooking to correctly search components created directly by UBlueprints, as well as the CDO components it already covered. Also explicitly mark subobject templates as editor only.
Fix issue where the AssetImportData associated with Blueprint-owned Curves was ending up in the cooked subobject template list. Stopped it from creating those objects, and mark the class editor only.
Change 3201736 on 2016/11/17 by Steve.Robb

#fyi robert.manuszewski
Change 3201938 on 2016/11/17 by Ben.Woodhouse

Change 3204854 on 2016/11/18 by Steve.Robb
UEnumProperty.
Change 3205027 on 2016/11/18 by Ben.Zeigler
Add useful functions to FAssetPtr and TAssetSubclassOf that already existed on TAssetPtr
Add Get() to TSubclassOf so it matches our other wrappers
Fix TSubclassOf and TAssetSubclassOf to use the more efficient template method of checking class compatibility
Comment and template cleanups for AssetPtr, StringAssetReference, LazyPtr, and SubclassOf
Change 3206334 on 2016/11/21 by Ben.Zeigler
#UE-38773: Fix it so non-component template subobjects of CDOs are not included as creation dependencies for BP classes, also clean up GetPreloadDependencies as it was adding redundant and null entries
#UE-38799: Fix it so WidgetTrees don't get picked up as subobjects, and add ensure at cook time to find null outers that would crash at runtime. Make sure the instanced widget trees are transient.
Cook finishes but game is still crashing in some cases, so I might adjust this after other testing
Change 3206353 on 2016/11/21 by Ben.Zeigler
Fix EnumProperty to handle EDL preload dependencies properly
Change 3206625 on 2016/11/21 by Ben.Zeigler
Fix enum property crash at runtime by copying what array property does and making sure inner property is not transient
Change 3206937 on 2016/11/21 by Ben.Zeigler
#jira UE-38905 Fix it so enums inside arrays are migrated properly, the enum tag is lost so use the current one
Disable other nested enum migrations as they are unlikely to work. Array property tags need to be refactored to be safer
Correctly save enum tag for enum properties, it was being set but not serialized
Change 3207002 on 2016/11/21 by Ben.Zeigler
#jira UE-38799
Fix it so per-widget copy of widget tree and all widgets inside are properly transient, they were being cooked before but never accessed.
Fix case where non ClientOnly public objects nested instead ClientOnly objects would cook but fail to load, and add ensure to catch these cases in the future.
If the full outer chain isn't available, it can't be loaded anyway, and this finds issues at cook time instead of load time.
We should generally outlaw non-transient objects with transient outers, it does not do what people expect.
Change 3207032 on 2016/11/21 by Ben.Zeigler
#jira UE-38654 Re-Fix EDL cooking with SCS-added components. They used to have the DefaultSubObject flag but no longer do

Change 2762632 on 2015/11/11 by Steve.Robb@Dev-Core
Some TSet function optimisations:
Avoiding unnecessary hashing of function arguments if the container is empty (rather than the hash being empty, which is not necessarily equivalent).
Taking local copies of HashSize during iterations.
Change 2762936 on 2015/11/11 by Steve.Robb@Dev-Core
BulkData zero byte allocations are now handled by an RAII object which owns the memory.

[CL 2772222 by Robert Manuszewski in Main branch]
CL# 2698724:
UHT speed improvements:
Code is now generated with tabs, rather than going through a separate Tabify step.
Some expensive temporaries created during iteration and during iteration have been removed.
FFunctionData::FunctionDataMap now uses unique ownership instead of shared ownership.
TCString::Spc (and the new TCString::Tab) now uses a compile-time array instead of one generated at runtime with a static.
TSet::Compact no longer rehashes if no compaction was performed.
TArray assignment no longer reallocs to the same capacity.
[CL 2698780 by Steve Robb in Main branch]
I have reviewed each change carefully, but it is a large change and I could have missed something! Here is a summary of the types of changes in this CL:
* Made nullptr checks consistent (the plurality of the changes are of this type)
* Completed switch statements (IE, switch did not explicitly handle default case, but had unhandled enum entries - this is the second most popular type of fix)
* Removed unused variables
* Removed redundant initializations
* WidgetNavigationCustomization.cpp was fixed by the owner
* integers converted to floats where result was stored in a float
* Removed redundent null checks (e.g. before delete statements)
* Renamed variables to prevent non-obvious shadowing
* Fixed use of bitwise & when checking for equality to an enum entry (which is often 0)
* Fixes for some copy paste errors (e.g. FoliageEdMode.cpp)
[CL 2498053 by Dan Oconnor in Main branch]
EPropertyReferenceFlags removed too, because it is unused.
