Change 3131279 on 2016/09/19 by Mike.Beach

	#jira UE-36097

Change 3131318 on 2016/09/19 by Phillip.Kavan

	[UE-35690] Minor revisions to Blueprint SCS execution to improve efficiency and address an out-of-order registration issue.

	change summary:
	- modified AActor::PostSpawnInitialize() to defer native component registration if there is no native scene root component set and if the actor is a BP type (i.e. will invoke SCS). this means that native actor classes with only non-scene components will now defer registration/post-registration until after SCS execution has established a valid scene root.
	- modified AActor::ExecuteConstruction() to gather the set of native scene components that SCS nodes can attach to before invoking the SCS. this was previously being done redundantly within the SCS itself at each level of the BP class inheritance hierarchy.
	- modified AActor::ExecuteConstruction() to do a final registration pass over all components after the all SCS levels have been executed. this was also previously being done within the SCS at each level. this avoids some extra redundancy.
	- modified USCS_Node::ExecuteNodeOnActor() to call RegisterAllComponents() on the given actor instance after establishing a valid scene root component if it was previously deferred at spawn time.
	- modified USCS_Node::ExecuteNodeOnActor() to now register components after they're created. since SCS execution goes from parent to child, parent scene components will always be registered before their children. non-native, non-scene component registration will also be deferred until a scene root component has been established.
	- added AActor::HasDeferredComponentRegistration()
	- modified AActor::RegisterAllComponents() to reset the actor's deferred component registration flag when called
	- modified AActor::AddComponent() to check the 'bAutoRegister' flag before calling RegisterComponent() (for consistency)
	- moved the RegisterInstancedComponent() utility method into USimpleConstructionScript and modified it to ensure that parent attachments are registered before their children.
	- modified USimpleConstructionScript::ExecuteScriptOnActor() to include an additional input parameter for passing in the set of native scene components that can be attached to.
	- modified USimpleConstructionScript::ExecuteScriptOnActor() to remove redundant/unnecessary work as noted above.

	#jira UE-35450

Change 3136508 on 2016/09/22 by Mike.Beach

	Removing a bIsVisible guard for level Blueprint menu actions - this was causing level BP options to disappear when you hid sub-levels. The guard doesn't seem to matter, as those actions will be removed with the world (when it is updated, or unloaded).

	#jira UE-34019

Change 3137587 on 2016/09/23 by Maciej.Mroz

	#jira ODIN-1017 [Nativization] Crash while loading Hub_env level

	Merged cl#3137578 from Odin branch

Change 3137666 on 2016/09/23 by Ben.Cosh

	This adds the ability to map composite graph instances in the same way we map macro instances for blueprint debug data and improves the quality of the debug data providing correct information for nested macro/composite instances at any script location in instrumented blueprint compilations.
	#Jira UE-33396 - Nested macro nodes don't map correctly if you place multiple instances in the same graph
	#Proj KismetCompiler, BlueprintGraph, UnrealEd

	- This is the first part of a two part change, the subsequent change will make use of the debug output to resolve complex trees of tunnel instances in the blueprint profiler.

Change 3137800 on 2016/09/23 by Phillip.Kavan

	[UE-34896] Properties are now generated for client-only Blueprint components in an uncooked server-only context.

	change summary:
	- bumped BlueprintObjectsVersion
	- added a new 'ComponentClass' property to USCS_Node
	- added a new 'ComponentClass' field to the FComponentOverrideRecord struct (UInheritableComponentHandler)
	- added a USCS_Node::Serialize() override to fix up 'ComponentClass' on load (so that it's set prior to compile-on-load)
	- modified USimpleConstructionScript::CreateNodeImpl() to set the ComponentClass property in a new SCS node
	- modified USimpleConstructionScript::ValidateNodeTemplates() to consider the node to be valid if ComponentClass is set and is known to be filtered (i.e. the node will not be removed in this case)
	- modified USimpleConstructionScript::ValidateNodeTemplates() to emit a warning message in an uncooked client-only or server-only context if the ComponentClass could not be set in an existing package (i.e. if a resave is needed)
	- modified UInheritableComponentHandler::PostLoad() to fix up 'ComponentClass' on load
	- modified UInheritableComponentHandler::CreateOverridenComponentTemplate() to set the ComponentClass field in a new override record
	- modified UInheritableComponentHandler::IsRecordValid() to consider the record to be valid if ComponentClass is set (when ComponentTemplate is NULL)
	- modified UInheritableComponentHandler::IsRecordNecessary() to consider the record to be necessary if ComponentClass is set and is known to be filtered
	- modified FKismetCompilerContext::CreateClassVariablesFromBlueprint() to use 'ComponentClass' rather than 'ComponentTemplate' to infer the property subtype

	#jira UE-34896

Change 3137851 on 2016/09/23 by Phillip.Kavan

	[UE-36079] Component overrides in a child blueprint will no longer trigger a warning message when the original component is removed from its parent.

	change summary:
	- modified UInheritableComponentHandler::IsRecordValid() to no longer consider a NULL OriginalTemplate to be invalid (so that the warning message is suppressed)
	- modified UInheritableComponentHandler::IsRecordNecessary() to consider a NULL OriginalTemplate to be unnecessary (so that the record is still removed in this case)

	#jira UE-36079

Change 3137948 on 2016/09/23 by Ben.Cosh

	CIS warning fix on mac for out of order initialisation.

Change 3139351 on 2016/09/25 by Ben.Cosh

Change 3139641 on 2016/09/26 by Maciej.Mroz

	#jira UE-31099 Renaming an input mapping does not generate a warning when compile a blueprint using that input

	Since we cannot distinguish which nodes are isolated by users (and shouldn't be validated) and which nodes are isolated during expansion step (and should be validated), the isolated nodes are pruned both before and after expantion step (and validation).

Change 3139961 on 2016/09/26 by Ben.Cosh

	CIS static analysis fix for CL 3137666

	- missed one of the warnings in a previous attempt.

	#jira UE-34961 Assert when calling BP function with weak object parameter.

	BP doesn;t support weak obj ptr as parameters - Validation added. Function, created from colappsed nodes, cannot have a parameter of weakptr type.

Change 3148022 on 2016/10/01 by Phillip.Kavan

	[UE-21109] Fix component instance data loss after renaming SCS component nodes at the Blueprint class level.

	change summary:
	- deprecated the public USCS_Node::VariableName member and replaced it with an internal-only member accessible via Get/Set method (i need to be in control of the set logic)
	- changed all occurrences of direct access to USCS_Node::VariableName to use a GetVariableName() call (since it's now internal)
	- simplified USCS_Node::GetVariableName() as what it used to do was legacy and thus is no longer necessary (it's been handled by USimpleConstructionScript::PostLoad for awhile now)
	- added USCS_Node::SetVariableName(); this now renames the component template (if valid) and all instances of it prior to changing the internal variable name. this ensures that archetype lookups will continue to function after a rename.
	- added USCS_Node::RenameComponentTemplate() to handle SCS node component template rename logic on a variable name change
	- switched the AActor::CheckComponentInstanceName() API to be publically-accessible; need to call this when renaming instanced components to match a new variable name in order to ensure that we rename any instance-only components out of the way first (this is the same logic that we run when constructing component instances on map load/RRCS, so it's consistent)
	- modified UInheritableComponentHandler::PostLoad() to fix up the component template within each record to match the original template object name. this ensures that ICH-specific archetype lookups will continue to function after a rename. it also ensures that any mismatched template names in existing assets will now be fixed up on load.
	- moved UActorComponent::ComponentTemplateSuffixName into the USimpleConstructionScript class (since the association is tied to templates created by that class specifically). note: this revises a change from a recent PR submission.
	- modified UpdateAttachedIsEditorOnly() to check the RF_ArchetypeObject flag rather than the ComponentTemplateSuffixName (part of the revision to the recent PR submission noted above)

	#jira UE-21109

Change 3148023 on 2016/10/01 by Phillip.Kavan

	[UE-35562] Fix inherited Blueprinted component template defaults data loss in child Blueprint classes after recompiling the Blueprinted component class.

	change summary:
	- added a local FArchetypeReinstanceHelper struct + GetArchetypeObjects()/FindUniqueArchetypeObjectName() utility method implementations to KismetReinstanceUtilities.cpp
	- modified FBlueprintCompileReinstancer::ReplaceInstancesOfClass_Inner() to ensure that the full inherited component template (archetype) ancestry is renamed along with the base template when we rename the base template object away from its original name in order to make way for the new (reinstanced) template. the names must match the base template along the entire inheritance hierarchy in order for forward/reverse inherited component archetype lookups to succeed.

	notes:
	- BP (non-native) component templates (e.g. SCS/AddComponent nodes) that belong to the class being reinstanced (i.e. whose templates are not inherited from a parent BP) always inherit directly from the component CDO, and thus do not require this code path (that is, archetype lookups are not dependent on matching the CDO by name). similarly, native components (defined in C++) are included as part of the CDO defaults data, and thus also do not require this code path.

	#jira UE-35562

Change 3148030 on 2016/10/01 by Phillip.Kavan

	UT fixes for CIS warnings related to SCS node API changes.

Change 3149001 on 2016/10/03 by Ben.Cosh

	This fixes an issue found with the instrumented blueprint compilations in which a certain compilation path would not provide the extended composite tunnel node heararchy in debug data and removes an unneceassary check that was causing problems.

Change 3149667 on 2016/10/03 by Mike.Beach

	Fixing up some Ocean content errors as fallout from a change in Dev-Blueprints - the errors properly identified a node that was using a culled input that was uninitialized.

	#jira UE-36770

Change 3149777 on 2016/10/03 by Mike.Beach

	Fixing up  an Orion content warning - disconnecting a cast path in Hero_Automation, now that the node is producing a warning (the cast is impossible, and therefore the path is superfluous).
