Change 2789867 on 2015/12/04 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream1
UnrealHeaderTool plugins no longer need to be a separate plugin and don't require UnrealHeaderTool source code changes to work.
- Merged ScriptGeneratorPlugin with ScriptPlugin
- Introduced the concept of UHT plugin support for plugins so that UHT's source files don't need to be modified to make it work with external plugins
- Added RuntimeNoProgram module type (module that can be used at runtime but not by program targets).
- Fixed logic with project file path setting in the engine. It will no longer try to crate a full path from an already rooted path.

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
CrashReportServer moved out of the not for licencees, a few fixes, removed RegisterPII

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
GitHub #1793 - File write flags argument
Change 2780590 on 2015/11/25 by Steve.Robb@Dev-Core

Change 2782538 on 2015/11/30 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream1
#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.

#ttp 306334 - ROCKET: TASK: PUNTABLE: Stats: FN: Make diagnostic stats discoverable and available in the UI (don't require console to toggle)
#branch UE4
#change
DECLARE_STATS_GROUP û Added additional param GroupCategory, for subfolder use in the UI. Fixedup all Stats Group usage so the category is now propagated through where it needs to be.
Currently all Group stats have the Category æAdvancedÆ, and all engine stats have the Category æSimpleÆ û this is just to differentiate them for now, better categories will come along in future.
Modified FindOrAddMetaData as it now broadcasts a delegate (via a TaskGraph) whenever a new stat meta data is added û this was needed as not all the stat groups are æregisteredÆ when the level viewports are created (they are drip loaded), so the viewports need to listen for any additions thereafter...
GroupDescription is displayed as a tooltip in the UI for the stat entry and we may want to localize these.
RenderStats & RenderGroupedWithHierarchy: Modified so that it now takes the viewport that it should render to as a param (which is also used to determine if each stat should be visible).
Removed StatsEnabled delegate in favour of StatCheckEnabled, StatEnabled, StatDisabled, StatDisableAll for more finite usage and feedback when toggling them.
Modified FHUDGroupManager HandleCommand It now uses the new delegates to work out whether it needs to enable or disable for the current viewport, so itÆs more involved than a simple toggle, itÆs more ôis the stat enabled for the current viewport, and is it enabled for any viewportö delegate querying so it can react accordingly.
Added struct FSimpleStatFuncs: Which contains info on each æSimple StatÆ such as; name, category, description, renderfunc, togglefunc and the side of the viewport it should be rendered to
ExecSimpleStat û Calls Exec for a registered Simple Stat, ensuring the correct viewport is set
IsSimpleStat û Checks to see if a stat is a registered Simple Stat or not
SetSimpleStat û Sets the state of a specified Simple Stats
SetSimpleStats - Sets the state of the specified Simple Stats
RenderSimpleStats û Renders the Simple Stats if they are enabled, and have Render functions assigned.
Each Exec function had the code it executes which itÆs toggled and rendered into functions
Added FStatUnitData & FStatHitchesData: Moved all the globals/static variables used when enabling Stat Unit/Hitches into a struct as itÆs now used by multiple viewports and they needed their own copies. Also moved their draw functions here too.
FSceneViewport:
SwapStatCommands û Exchanges the enabled stats between two viewports, this is so when PIEing the stats which were enabled on the Level Viewport (if playing in active viewport only) get transposed to the Game Viewport, and then restored when PIE ends.
SEditorViewport:
ToggleStatCommand û Called when a stat is enabled/disabled from the UI
IsStatCommandVisible û Checks to see if a stat command should appear as visible in the UI
SEditorViewportViewMenu:
GenerateViewMenuContent û Made protected and virtual so it could be called externally.
FLevelViewportCommands: Added the code needed to generate commands for each of the Stat menu entries, however because not all stats are registered when this happens, it also creates some delegates to listen out for others that are registered later
Destructor û Needed to reset delegates
HandleNewGroupStat û Creates the new group stat commands
HandleNewStat û Creates the new stat command
FindStatIndex û Looks for where a stat should be inserted in the menu in order to maintain alphabetical order
SLevelViewport:
Modified the code so that the states of all the SimpleStats are saved so they can be restored next time the editor is ran (previously just handled FPS).
OnFloatingButtonClicked û Called whenever any of the level viewports floating buttons are clicked in order to correctly set the ælastÆ viewport global
OnToggleAllStatCommands û Called when the user selects æHide AllÆ from the viewport.
ToggleStatCommand û Called when the user selects any other stat option from the viewport.
BindStatCommand û Used to bind the menu action to the command name (used by delegate)
Added SLevelEditorViewportViewMenu (extends SEditorViewportViewMenu), and overrode GenerateViewMenuContent so that OnFloatingButtonClicked can be called whenever the menu is clicked on. This is also called during GenerateOptionsMenu, GenerateCameraMenu, GenerateShowMenu & OnToggleMaximize
Added global ptr GStatProcessingViewportClient (sim to Current, Last) used to keep track of which viewport the stat should be applied too (only valid within the scope of the Exec call).
FViewportClient:
Moved global ESoundShowFlags enum list into this class.
FCommonViewportClient:
Destructor û Needed to reset GStatProcessingViewportClient
FLevelEditorViewportClient
SetCurrentViewport û moved code responsible for setting the global æcurrentÆ viewport ptr into a func
SetLastKeyViewport û moved the code responsible for settings the global ælastÆ viewport ptr into a func
UGameViewportClient:
Destructor û Needed to cleanup delegate usage.
FViewportClient & FLevelEditorViewportClient & UGameViewportClient*
GetStatUnitData û The viewports copy of the variables needed when running the Stat Unit Exec
GetStatHitchesData û The viewports copy of the variables needed when running the Stat Hitches Exec
GetEnabledStats û Gets a list of all the stats which are enabled for the viewport
SetEnabledStats û Sets a list of all the stats which should be enabled for the viewport
IsStatEnabled û Checks to see if a specific stat is enabled for the viewport
SetStatEnabled û Sets a specifics stats state to enabled or disabled
GetSoundShowFlags û Gets which flags are enabled for the Stat Sounds Exec
SetSoundShowFlags û Sets which flags are enabled for the Stat Sounds Exec
HandleViewportStatCheckEnabled (delegate) û checks to see if a specific stat is enabled on this viewport
HandleViewportStatEnabled (delegate) û enables a specific stat for the viewport
HandleViewportStatDisabled (delegate) û disables a specific stat for the viewport
HandleViewportStatDisableAll (delegate) û disables all stats for the viewport
*FViewportClient has dummy virtual funcs and LevelEditor/Game both have the same implementations, the only differences is the GameViewports member variables are static so that the stat info persists between runs.
FLevelEditorViewportInstanceSettings deprecated bShowFPS in favour of an EnabledStats array (so we can track the state of all stats, not just FPS).
Added new config var bSaveSimpleStats: if enabled, restores previously enabled level viewport simple stats the next time the editor runs (defaults to false).
Modified FillShowFlagMenu so that thereÆs just one func and you specify where (if any) youÆd like a separator to occur.
Added FillShowStatsSubMenus so that menus can be generated which have submenus
Added the Stats sub menu to the View menu
Modified Execs so that the GStatProcessingViewportClient is set to the correct default viewport (if it wasnÆt specified), and clears again after itÆs been processed
HandleStatCommand now takes World and ViewportClient as params too û needed when Execs enabled other Execs so the world/viewport persists.
SetAverageUnitTimes û Added as a Setter func for GetAverageUnitTimes (moved code out of Stat Unit renderer and modified so that it only updates once per frame).
Stripped out all unneeded globals
