Change 2716841 on 2015/10/05 by Mike.Beach
(WIP) Cleaning up how we setup script assets for replacement on cook (aligning more with the Blueprint conversion tool).

Change 2719361 on 2015/10/07 by Maciej.Mroz
Generated native code for AnimBPGC - some preliminary changes.
Refactor: UAnimBlueprintGeneratedClass is not accessed directly in runtime. It is accessed via UAnimClassInterface interface.
Properties USkeletalMeshComponent::AnimBlueprintGeneratedClass and UInterpTrackFloatAnimBPParam::AnimBlueprintClass were changed into "TSubclassOf<UAnimInstance> AnimClass"
The UDynamicClass also can deliver the IAnimClassInterface interface. See UAnimClassData, IAnimClassInterface::GetFromClass and UDynamicClass::AnimClassImplementation.

Blueprint Compiler Cpp Backend
- Anim Blueprints can be converted
- Various fixes/improvements
Change 2721310 on 2015/10/08 by Maciej.Mroz
refactor (cl#2719361) - no "auto" keyword
Change 2721727 on 2015/10/08 by Mike.Beach
(WIP) Setup the cook commandlet so it handles converted assets, replacing them with generated classes.
- Refactored the conversion manifest (using a map over an array)
- Centralized destination paths into a helper struct (for the manifest)
- Generating an Editor module that automatically hooks into the cook process when enabled
- Loading and applying native replacments for the cook
Change 2723276 on 2015/10/09 by Michael.Schoell
Blueprints duplicated for PIE will no longer register as dependencies to other Blueprint.
#jira UE-16695 - Editor freezes then crashes while attempting to save during PIE
#jira UE-21614 - [CrashReport] Crash while saving during PIE - FKismetEditorUtilities::CompileBlueprint() kismet2.cpp:736
Change 2724345 on 2015/10/11 by Ben.Cosh
Blueprint profiler at first pass, this includes the ability to instrument specific blueprints with realtime editor stat display.
#UEBP-21 - Profiling data capture and storage
#UEBP-13 - Performance capture landing page
#Branch UE4
#Proj BlueprintProfiler, BlueprintGraph, EditorStyle, Kismet, UnrealEd, CoreUObject, Engine
Change 2724613 on 2015/10/12 by Ben.Cosh
Incremental update for blueprint profiler to fix the way some of the reported stats cascade through events and branches and additionally some missed bits of code are refactored/removed.
#Branch UE4
#Proj BlueprintProfiler
#info Whilst looking into this I spotted the reason why the stats seem so erratic, There appears to be an issue with FText's use of EXPERIMENTAL_TEXT_FAST_DECIMAL_FORMAT which I have reported, but ideally disable this locally until a fix is integrated.
Change 2724723 on 2015/10/12 by Maciej.Mroz
Constructor of a dynamic class creates CDO.

Change 2725108 on 2015/10/12 by Mike.Beach
[UE-21891] Minor fix to the array shuffle() function; now processes the last entry like all the others.
Change 2726358 on 2015/10/13 by Maciej.Mroz
UDataTable is properly saved even if its RowStruct is null.

Change 2727395 on 2015/10/13 by Mike.Beach
(WIP) Second pass on the Blueprint conversion pipeline; setting it up for more optimal (speedier) performance.
* Using stubs for replacements (rather than loading dynamic replacement).
* Giving the cook commandlet more control (so a conversion could be ran directly).
* Now logging replacements by old object path (to account for UPackage replacement queries).
* Fix for [UE-21947], unshelved from CL 2724944 (by Maciej.Mroz).

Change 2727484 on 2015/10/13 by Mike.Beach
[UE-22008] Fixing up comment/tooltip typo for UActorComponent::bAutoActivate.
Change 2727527 on 2015/10/13 by Mike.Beach
Downgrading an inactionable EdGraph warning, while adding more info so we could possibly determine what's happening.
Change 2727702 on 2015/10/13 by Dan.Oconnor
Fix for crash in UDelegateProperty::GetCPPType when called on a function with no OwnerClass (events)
Change 2727968 on 2015/10/14 by Maciej.Mroz
Since ConstructorHelpers::FClassFinder is usually static, the loaded class should be in root set, to prevent the pointer stored in ConstructorHelpers::FClassFinder from being obsolete.
FindOrLoadClass behaves now like FindOrLoadObject.

[CL 2391686 by Michael Schoell in Main branch]
this change introduces enforcement of 'const-correctness' into implemented function graphs.
summary:
if you have a function declared in C++ like this:
UFUNCTION(BlueprintImplementableEvent)
int32 MyFunctionThatReturnsSomeValue() const;
if you implement that (BPIE) function in a Blueprint that's parented to that native class, it will now be flagged as 'const'. this makes any properties of 'self' read-only within the context of that graph, which means the compiler will emit an error if you try to set a property or otherwise call a non-const, non-static function with 'self' as the target.
if there happens to already be an implemented const function in a Blueprint that was in place prior to this change, the compiler will emit a warning instead of an error, in order to allow existing Blueprints that may currently be "violating" const within the context of a const BPIE function to still compile, while still alerting to issues that should probably be addressed.
notes:
1) this also applies to BlueprintNativeEvent (BPNE) implementations, and also when implementing BPIE/BPNE interface methods that are also declared as const
2) a const BPIE/BPNE function with no return value and no output parameters will be implemented as a "normal" impure function, and not as an event as in the non-const case
3) a const BPIE/BPNE function with a return value and/or output parameters will currently be implemented as a pure function, regardless of whether or not BlueprintCallable is specified
4) this CL also retains some consolidation of static function validation code that i had previously done, mostly to allow static functions to more easily be whitelisted for const function graphs

[CL 2368059 by Phillip Kavan in Main branch]
A function with a World Context pin can also be flagged with new metadata CallableWithoutWorldContext which indicates it can be used in any context, even if GetWorld() is not implemented, the called function is responsible for providing a working alternative when World is null
World Centric functions can also be used in classes tagged with the ShowWorldContextPin metadata which indicates the class has a well defined method of supplying the world context that will be connected
