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 3149443 on 2016/10/03 by Max.Preussner
MediaAssets: Better parameter names for MediaPlayer BP functions
Change 3149756 on 2016/10/03 by Max.Chen
Sequence Recorder: Set some settings to be clamped at 0 (sequence length, recording delay, audio gain, audio input buffer size, nearby actor recording proximity)
#jira UE-35233
Change 3149795 on 2016/10/03 by Max.Chen

#jira UE-36807
Change 3151414 on 2016/10/05 by Max.Chen

#jira UE-35285
Change 3152038 on 2016/10/05 by Max.Preussner
UdpMessaging: Code & documentation modernization pass
Change 3152471 on 2016/10/05 by Max.Chen
Cine Camera: Don't enable/disable actor ticking based soley on actor tracking since actor ticking is needed for other purposes. Instead, always enable actor ticking and only update actor tracking on tick if necessary. This fixes a
bug where the cine camera actor won't tick if you hook in event tick.
#jira UE-36625
Change 3152692 on 2016/10/05 by Max.Preussner
Messaging: API code & documentation modernization pass
Mostly removed shared pointer/ref typedefs as they prevent forward declarations and increase include complexity.
Change 3153824 on 2016/10/06 by Max.Preussner
Messaging: Renamed IConnectionBasedMessagingModule to ITcpMessagingModule and moved it into TcpMessaging
I recommend that we refactor this API. The dependency should be reversed, i.e. instead of AndroidDeviceDiscovery depending on the TcpMessaging plug-in module, the Engine should provide a central registry that device discovery
modules can notify, and that message transport plug-ins can register with and listen to OnConnectionAdded/Removed events etc. That way it supports an arbitrary number of transport plug-ins, and the Engine is not coupled to any of them. This
functionality is not necessarily related to messaging, and the Messaging API is transport agnostic anyway. I'll think about this some more.
Change 3153826 on 2016/10/06 by Max.Preussner
Messaging: Removed remaining typedefs in IMessageTracer to enable forward declaration and reduce include dependencies
Change 3153857 on 2016/10/06 by Max.Chen
Sequencer: Set snap time to dragged key on by default.
Change 3153980 on 2016/10/06 by Max.Preussner

Change 3154313 on 2016/10/06 by Max.Chen
Sequencer: Set the paste keys time to the current time, rather than the mouse time.
Change 3154332 on 2016/10/06 by Max.Chen

Change 3154377 on 2016/10/07 by Max.Chen
Sequencer: Add ability to step to beginning and ends of sections/shots using the hotkeys: , and .
Change 3154788 on 2016/10/07 by Max.Chen
Sequencer: Fix offsets that created when moving multiple sections. The offsets were being created because section bounds were being generated for all sections except for the current section. Instead, they should be computed for all
sections except for any that aren't being moved.

Change 3168626 on 2016/10/19 by Max.Chen
Sequencer: Clamp to view bounds should snap to frame if frame snapping is on.
Change 3168627 on 2016/10/19 by Max.Chen

#jira UE-35473
Change 3171743 on 2016/10/24 by Andrew.Rodham
Editor: Added support for detail customizations on root structs
- Also added the ability to add external struct data onto a detail category builder, and property type customization.
Change 3171752 on 2016/10/24 by Andrew.Rodham
Sequencer: Fixed spawnable ownership
- Spawnables are no longer destroyed when the cursor leaves the master playback range.
- Spawnable ownership now operates as it previously did before the evaluation rework.
- bIgnoreOwnershipInEditor has been removed since its existence was a work around for when we didn't evaluate sub sequences from the master sequence.
- FMovieSceneSequenceID is now a struct so that it can be used in array properties
- Meta data now exists for each segment of an evaluation field. Currently this only includes the sub sequence IDs that exist at that time, but it may be expanded to include all evaluation entities (tracks + sections) in future so
we don't have to calculate that at runtime.
Change 3171756 on 2016/10/24 by Andrew.Rodham
Sequencer: Added ability to trigger events with parameters
- It's now possible to supply an event payload on event track keys which are to be passed to a given event. The structure must match the signature of the event, or a warning will be emitted.
- Added a templated TGenericKeyArea, TKeyFrameManipulator and TCurveInterface that allow to generic manipulation of keyframe section data. In time we will port the other key areas over to this representation.
- This new architecture affords the common manipulation of time-based keyframes in a value-agnostic manner.

MAJOR FEATURES + CHANGES
==========================
Change 2783106 on 2015/11/30 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream2
Introduced GC UObject clusters. GC clusters provide means to create disregard for GC subsets at load time (e.g. Materials with material expressions and their textures).
- Saves about 25ms in reachability analysis (58ms -> 33ms)
- UObject classes/instances can now be marked as cluster root objects with CanBeClusterRoot() function override.
- Cluster creation is automatic. Clusters don't require any manual handling for GC to collect them when nothing is referencing them.
- Moved token stream processing to a new class FFastReferenceFinder to make it more generic and re-usable by other code
- Removed REFERENCE_INFO macro from GC code and replaced it with a local variable (saves about ~1.9ms: 33.2ms -> 31.3ms)
Change 2773094 on 2015/11/19 by Steve.Robb@Dev-Core
Multicast script delegate check for existing bindings replaced with ensure.
Multicast native delegate no longer checks for existing bindings.
Removal of old delegate code.
Some FORCEINLINEing to improve debugging experience of stepping into delegate code.
Change 2782180 on 2015/11/27 by Graeme.Thornton@GThornton_DesktopMaster
Make scoped seconds timer class available outside of stats build. Normal usage macros still remain guarded
Added SCOPE_SECONDS_COUNTER_RECURSION_SAFE which only times during the outmost instance of a recursive function
Added SCOPE_SECONDS_COUNTER_RECURSION_SAFE_BASE and SCOPE_SECONDS_COUNTER_BASE which are defined in all build types, for easy temporary timing in Test/Shipping builds.
Added a boolean parameter to the timer class which can be used to disable it without having to mess around with scoping the calling code
Change 2782635 on 2015/11/30 by Graeme.Thornton@GThornton_DesktopMaster
Added GetTimeStampPair() to the filemanager and platformfile interfaces. Requests timestamps for a pair of files where we assume that both files would always exist at the same wrapper level. Allows us to skip file system queries for localization package lookups where the native file is in a pak but the localized file doesn't exist.
Change 2775153 on 2015/11/20 by Jaroslaw.Surowiec@Stream.1.JarekSurowiec

Change 2773114 on 2015/11/19 by Steve.Robb@Dev-Core
FMath::IsPowerOfTwo is now templated to take any type.
Change 2773643 on 2015/11/19 by Steve.Robb@Dev-Core
GetDelegateInstance() calls replaced - delegate instances never compare equal unless you are comparing two unbound delegates (both null) or comparing a delegate with itself.
Change 2777686 on 2015/11/23 by Steve.Robb@Dev-Core

#UE4 Removed DiskCachedAssetDataBuffer as it was not strictly necessary and was triggering a crash when loading the cached registry from disk. This data is now stored directly in DiskCachedAssetDataMap. It was already true that this map does not change outside of SerializeCache but now it is critical since NewCachedAssetDataMap keeps pointers directly to its values.
Asset registry fixes by Bob Tellez. Possible fix for UE-23783.
Change 2782564 on 2015/11/30 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream1
FReferenceCollector::AddReferenceObjects performance improvements for TArrays. ARO will no longer call HandleObjectReference multiple times but instead will call HandleObjectReferences just once (currently only implemented for FGCCollector). Reduces the number of virtual function calls while GC'ing.
Change 2782716 on 2015/11/30 by Steve.Robb@Dev-Core
UObject serial number array initialized for debug visualization.
Change 2782933 on 2015/11/30 by Steve.Robb@Dev-Core
Critical sections are no longer copyable.
Change 2783061 on 2015/11/30 by Steve.Robb@Dev-Core
* 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.

- Misc tweaks to make profiler more base on the new stats system
- Added a new view mode to the data graph, for the regular stats file it will be LineIndexBased, for the raw stats file it will be ThreadViewTimeBased
- Added profiler stream, a new class that will hold all data read from the raw stats file, hopefully will replace the current profiler data provider/ data source later
- Added basic support for the second profiler view mode
