Change 3050029 on 2016/07/14 by Ben.Cosh
This modifies the blueprint instrumented compilation chain so only the the blueprint you compile and all dependencies are instrumented and the profiler is notified rather than waiting for event data.
#Jira UE-32063 - The blueprint profiler doesn't display any stats in the execution graph if no instance is placed in the current level.
#Proj BlueprintProfiler, Kismet, UnrelEd
- This also improves the execution graph UI, notifying the user that no instances are available to display data from.

[UE-33017] Don't include transient properties when generating property lists at cook time for optimized runtime Blueprint component instancing. Also ensure that deprecated properties are serialized during load/instancing at runtime.
change summary:
- modified FBlueprintComponentInstanceDataLoader to append 'PPF_UseDeprecatedProperties' to the FArchive port flags.
- modified FBlueprintComponentInstanceDataWriter to append both 'PPF_Duplicate' and 'PPF_UseDeprecatedProperties" to the FArchive port flags (to ensure consistency w/ the instancing side).
- switched the RecursivePropertyGatherLambda helper to a static class method instead
- modified the RecursivePropertyGather utility method to exclude transient properties.
notes:
- the primary cause of UE-33017 was that UBodySetup can "share" the ShapeBodySetup object across all instances, but the shared object is not owned by the CDO, it's owned by the archetype. this caused the archetype to differ from the CDO, which caused us to emit the transient property at cook time. thsi threw off the serialization offset between read/write FArchive passes at runtime. since transient properties are not serialized as part of the template, there's no need to include them in the generated delta property list, so as a fix, i'm just excluding them altogether.

Change 3106261 on 2016/08/30 by Phillip.Kavan
[UE-34705] Gracefully handle tunnel node entry exec pins that aren't internally linked during BP profiler tunnel boundary mapping.
change summary:
- added FBlueprintFunctionContext::GetTunnelBoundaryNode() (uncheckedl variant).
- moved FBlueprintFunctionContext::GetTunnelBoundaryNodeChecked() impl into GetTunnelBoundaryNode().
- re-implemented FBlueprintFunctionContext::GetTunnelBoundaryNodeChecked() to call GetTunnelBoundaryNode() and then assert on the result.
- changed the FBlueprintTunnelInstanceContext::GetTunnelBoundaryNodeChecked() impl to override GetTunnelBoundaryNode() instead.
- modified FBlueprintFunctionContext::MapTunnelBoundary() to only process the entry case if the TunnelBoundaryNode result is valid. this way we simply skip tunnel boundary mapping if an entry path was not previously mapped (rather than assert).

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.

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.

#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.

All changes regarding e-mail discussion titled "Asset registry shenanigans".
Changes:
1. Engine now actively is getting rid of short asset paths in FStringAssetReference during saving (for all packages) and loading (only for older packages).
2. Deprecated direct access to FStringAssetReference.AssetLongPathname and exposed it via ToString and SetPath -- SetPath is making sure the path is in correct format. If the path can't be found on disk, the path is cleared.
3. Also access to FStringAssetReference.AssetLongPathnam via Blueprints is guarded using custom Make node function that uses SetPath instead of simple assign.
4. StringAssetReferenceMap will now contain only paths to packages (not objects) and ini references
5. GetDependencies now has additional parameter that lets you chose if it should resolve ini references or not. It was left not as default to keep old behaviour.
