Change 3499927 by Dan.Oconnor
UField::Serialize no longer serialize's its next ptr, UStruct::Serialize serializes all Children properties instead. This resolves a hard circular dependency between function libraries that EDL detected. It was resolved in an ad hoc way by the old linker

Fix issue where combined streamable handles could be freed before their complete callback is called if nothing external referenced them
Copy of CL#3544474
Change 3545456 by Ben.Zeigler
Allow PrimaryAssets to update their AssetData based on in-memory changes when launching 'Standalone Game' and 'Mobile Preview' from the editor. As it was, changes could be detected and propagated through UPrimaryDataAsset::PostLoad, but the changes would always reapply whatever already exists in the AssetRegistry. The primary use-case for this: making AssetBundle tag changes and allowing them to propagate without resaving/recooking all affected assets.

Change 3546528 by Ben.Zeigler
#jira UE-47548
Fix crash when a map's key type has changed but value has not, it was passing the UStruct defaults in when serialize was expecting the default instance, so pass null instead as we don't have the instance

Change 3553216 by Phillip.Kavan
#jira UE-39303, UE-46268, UE-47519
- Nativized UDS now support external asset dependencies and will construct their own linker import tables on load.
Change summary:
- Modified FCompactBlueprintDependencyData and FFakeImportTableHelper to be more relevant to UStruct and not just UClass-derivative types.
- Modified FBlueprintDependencyData to accept a single FCompactBlueprintDependencyData struct rather than its individual fields.
- Modified FBlueprintCompilerCppBackendBase::GenerateCodeFromStruct() to emit dependency assignment and static type registration functions for nativized UStruct types.
- Modified FBlueprintNativeCodeGenModule::FStatePerPlatform to include an array for tracking UDS assets that need to be converted during the nativization pass at cook time.
- Modified FBlueprintNativeCodeGenModule::GenerateFullyConvertedClasses() to generate nativized code for UDS assets. This ensures that UDS conversion falls under the same scope as BPGC conversion, so that they both feed into the same NativizationSummary context for asset dependency tracking (i.e. since we only have a single global dependency table in the codegen). Also modified InitializeForRerunDebugOnly() to do the same.
- Modified FBlueprintNativeCodeGenModule::Convert() to defer UDS conversion so that it's done at the same time as BPGC conversion (see note above).
- Modified FEmitDefaultValueHelper::AddStaticFunctionsForDependencies() to include support for UStruct types and to conform to changes made to FCompactBlueprintDependencyData.
- Modified FEmitDefaultValueHelper::AddRegisterHelper() to include support for UStruct types.
- Modified FBlueprintNativeCodeGenModule::FindReplacedClassForObject() to ensure that converted User-Defined Enum types are switched to a UEnumProperty at package save time so that any import tables contain the proper class. This is necessary because we nativize User-Defined Enum types as 'enum class' types, and UHT will generate code for those as a UEnumProperty with an "underlying" property. However, non-nativized User-Defined Enum types are referenced as a UByteProperty with a UEnum reference, so we have to fix up all the import tables before saving. Otherwise, EDL will assert on load (see UE-47519).
Change 3553301 by Ben.Zeigler
Fix ensure when passing literal None to SoftObjectPath, it now treats them as empty instead
Change 3553631 by Dan.Oconnor
UField::Serialize no longer serialize's its next ptr, UStruct::Serialize serializes all Children properties instead. This resolves a hard circular dependency between function libraries that EDL detected. It was resolved in an ad hoc way by the old linker. This change was originally submitted in 3499927, but it was incorrectly clearing the UField::Next pointer in UField::Serialize.
#jira UE-43458
Change 3553799 by Ben.Zeigler
Fix issue where calling WaitUntilComplete on a combined handle with Stalled children wouldn't work properly. It now forces all stalled children to start immediately. I also added a warning log when this happens and an ensure if somehow the force didn't work
Copy of CL #3553781
Change 3553896 by Michael.Noland
Blueprints: Allow the autowiring logic to better break and replace existing connections when made (e.g., when dragging a variable onto a compatible pin with an existing connection, break the old connection to allow the new connection to be made)
#jira UE-31031
Change 3553897 by Michael.Noland
Blueprints: Adjust search query when doing 'Find References' on variables from My Blueprints so that bound event nodes show up for components and widgets
#jira UE-37862
Change 3553898 by Michael.Noland
Blueprints: Add the name of the variable directly in the get/set menu options (when dragging from My Blueprints into the graph)
Change 3553909 by Michael.Noland
Blueprints: Added the full name of the type, container type (and value type for maps) to the tooltips for the type picker elements, so long names can be read in full
#jira UE-19710
Change 3554517 by Michael.Noland
Blueprints: Added an option to disable the comment bubble on comment boxes that appears when zoomed out
#jira UE-21810
Change 3554664 by Michael.Noland
Editor: Renamed "Find in CB" command to "Browse" and renamed "Search" (in BP) to "Find", so terminology is consistent and keyboard shortcuts make sense (Ctrl+B for Browse, Ctrl+F for find, not using the term Search anywhere)
#jira UE-27121
Change 3554831 by Dan.Oconnor
Non editor build fix
Change 3554834 by Dan.Oconnor
Actor bound event related warnings now show up in blueprint status when opening level blueprint for first time, improved warning message. Removed unused delegate and return value from FixLevelScriptActorBindings. Can now pass raw strings to blueprint results log (no need for Printf, although padding is not great), UClasses in compiler results log will open the generated blueprint when clicked on
#jira UE-40438
Change 3556157 by Ben.Zeigler
Convert LevelSequenceBindingReference to use FSoftObjectPath so it works properly with redirectors and fixups
Change 3557775 by Michael.Noland
Blueprints: Fixed swapped transaction messages when converting a cast node between pure and impure
#jira UE-36090

Blueprints: Add support for 'goto definition' on Create Event nodes when the Object pin is not hooked up
#jira UE-38912
Change 3560563 by Michael.Noland
Blueprints: Disallow converting a variable get node to impure/back when debugging (no graph mutating operations should be allowed)
Change 3561443 by Ben.Zeigler
Restore code to support gc.DumpPoolStats, was accidentally removed when FGCArrayPool was moved to a header.
Clean up comments around Cleanup function, the functionality to trim the memory pools was integrated into ClearWeakReferences on a prior change
Change 3561658 by Michael.Noland
Blueprints: Refactored 'Goto Definition' so there is no per-class logic in the Blueprint editor or schema any more; any node can opt in individually
- Added a key binding for Goto Definition (Alt+G)
- Added a key binding for Find References (Shift+Alt+F)
- Collapsed 'Goto Code Definition' for variables and functions into the same path, so there aren't separate menu items and commands
- Added new methods CanJumpToDefinition and JumpToDefinition to UEdGraphNode, the default behavior for UK2Node subclasses is to call GetJumpTargetForDoubleClick and call into FKismetEditorUtilities::BringKismetToFocusAttentionOnObject
- Going to a native function now goes thru a better code path that will actually put the source code editor on the function definition, rather than just opening the file containing the definition
Change 3562291 by Ben.Zeigler
Fix issue where calling FSoftObjectPtr::Get during a package save would result in that ptr being forever marked broken, because the ResolveObject fails during save. It's too risky to change that behavior, so change it so the TagAtLastTest doesn't get updated in that case
Change 3562292 by Ben.Zeigler
#jira UE-39042 When renaming or moving actors between levels it now attempts to fix any soft object references from blueprints or sequencer
When deleting actors that are soft referenced by actor/sequencer it will now warn the same way it does for level script. Added IAssetTools::FindSoftReferencesToObject to perform this search
Change it so saving a non-primary world does not result it being dirtied due to the temporary physics scene fixup
Fix issue where the actor name was shown incorrectly in the SSCS tree for actor instances, which meant that if you renamed it you would end up renaming it to the BP's name
Change 3564814 by Ben.Zeigler
#jira UE-47843 Don't set InputKey output pins to AnyKey if empty, this was causing blueprints with key events to constantly dirty themselves
Change 3566707 by Dan.Oconnor
Remove unused code, UClassGenerateCDODuplicatesForHotReload was attempting to create a CDO with a special name, which triggered an ensure. The Duplicated CDO was never used (callign code removed in 3289276 as it was a waste of cycles)
#jira None

Change 3567304 by Ben.Zeigler
Add bCheckRecursive option to IsEditorOnlyObject that is enabled by default and will check outer/archetype/class.
This is needed for places that call this function from outside of SavePackage.cpp when the editor only mark is set, such as the automation test code
Change 3567398 by Ben.Zeigler
Fix crash when spawning a widget that has no editor WidgetTree, but does have a cooked widget tree template due to tree inheritance
Change 3567729 by Michael.Noland
Blueprints: Clarified message about "{VariableName} is not blueprint visible" to define what that means "(BlueprintReadOnly or BlueprintReadWrite)"
Change 3567739 by Ben.Zeigler

Blueprints: Allow editing the tooltip of each enum value in a user defined enum
#jira UE-20036

#jira UE-47962
Change 3570179 by Michael.Noland
Blueprints: Fixed the tooltip of a user defined structure not updating immediately in the content browser after being edited
Change 3570192 by Michael.Noland
Blueprints: Added "(selected)" after the label (in the 'debug filter' dropdown in the Blueprint editor) for actors that are selected in the level editor, which should make it easier to choose the specific actor you want to debug
#jira UE-20709
Change 3571203 by Michael.Noland
Blueprints: Cleanup and refactoring to prepare for turning commented out nodes into an official feature
- Made EnabledState and bUserSetEnabledState private on UEdGraphNode and added new getters/setters
- Introduced IsAutomaticallyPlacedGhostNode() and MakeAutomaticallyPlacedGhostNode() to start decoupling the concept from commented out nodes
- Updated a couple of places that used a hardcoded UberGraphPages[0] into instead editing the most recently interacted with event graph if possible
- Updated 'is data only blueprint' logic to allow multiple ubergraph pages, as long as they're all empty of non-disabled nodes
Change 3571224 by Michael.Noland
Blueprints: Draw banners on development-only and user disabled nodes (excluding 'ghost' nodes like autogenerated event entries in new BPs)

#jira UE-29848
#jira UE-34698
Change 3571279 by Michael.Noland
Blueprints: Changed UK2Node::GetPassThroughPin so that only the execution wire on nodes with exactly one input and one output exec wire will have a corresponding pass-through pin (when there is ambiguity in which exec would be used, e.g., with a branch or sequence or timeline node, the subsequent nodes are now effectively disabled as well)
Change 3571282 by Michael.Noland
Blueprints: Fixed the tooltip for dragging a variable onto an inherited category not showing the 'move to category' hint
Change 3571284 by Michael.Noland
Blueprints: Made wires into/out of a user-disabled node draw verly dimly (other than the passthrough exec if it exists)
Change 3571311 by Ben.Zeigler
Add ActorIteratorFlags which allows overriding which types of actors/levels are iterated by ActorIterator, to allow iterating levels that are not visible.
All of the iteration logic is now in the base and the children just set different flags, which fixes it so TActorIterator does the same level collection check as FActorIterator
Change 3571313 by Ben.Zeigler
Several fixes to automation framework to allow it to work better with Cooked builds.
Change it so the automation test list is a single message. There is no guarantee on order of message packets, so several tests were being missed each time.

Change 3574985 by mason.seay
Updated comments and string outputs to list Soft Object Reference
Change 3575740 by Ben.Zeigler
#jira UE-48061 Change it so Editor builds work like cooked builds and always try to reuse existing packages when loading them instead of recreating them in place. Recreating in place does not work well for levels and blueprints, and blueprints already had a hack that was causing this behavior to not activate
Change 3575795 by Ben.Zeigler

Change 3577232 by Phillip.Kavan
#jira UE-48034 - Fix EDL assert on load caused by a native reference to a nativized BP class that also references a nativized UDS asset.
Change summary:
- Modified FNativeClassHeaderGenerator::ExportGeneratedStructBodyMacros() to emit the 'ReplaceConverted' package name for the FCompiledInDeferStruct global associated with the nativized UDS asset in the UHT codegen. This brings nativized UDS to parity with nativized BP class assets (it was likely just an oversight initially).

#jira UE-27124 Fix issue where renaming a map with legacy map build data would end up with a half-loaded redirector package, becuase the old map build data was still in use. It's possible the call to HandleLegacyMapBuildData should just be in World PostLoad instead of piecemeal in several other places but I am unsure.
Fix it so the redirector cleanup code on map change will not be stopped by non-standalone top level objects, which could be left behind by issues in other systems

Fix two compilation manager issues: Make sure CDOs are not renamed under a UClass, because they will be considered as possible subobjects, which has bad side effects and make sure that we update references even on empty functions, so that empty UFunctions are not left with references to REINST data
#jira UE-48240
Change 3579745 by Michael.Noland
Blueprints: Improve categorization and reordering support in 'My Blueprints'
- Allow drag-dropping functions, macros, delegates, etc... to reorder them within a category or to change categories (bringing them to parity with variables)
- Make category ordering on all categories sticky so you can reorder categories (the relative ordering will be the same within different sections like variables and functions)
- Added hover cues when drag dropping some items that were missing them (e.g., event dispatchers)
- Added support for renaming categories using F2
Known issues (none are regressions):
- Timelines cannot be moved to other categories or reordered
- Renaming a nested category will result in it becoming a top level category (discarding the parent category chain)
- Some actions do not support undo

Change 3581156 by Ben.Zeigler
#jira UE-48161 Fix issue where split pins would not be restored if a Struct type was changed due to refactoring of parent variables/functions. For structs we want to copy the pins, if they're invalid due to other changes they will be individual orphaned

#jira UE-47509 Rename and refactor internals StringAssetReferences and AssetPtrs to become SoftObjectPath/Ptr. This is to prepare them for use for subobjects like actors. Here is the rename table:
FStringAssetReference -> FSoftObjectPath
FStringClassReference -> FSoftClassPath
TAssetPtr -> TSoftObjectPtr
TAssetSubclassOf -> TSoftClassPtr
The old headers are deprecated, and FSoftClassPath is now in the same header has FSoftObjectPath.
This change increments the UE4 version because FSoftObjectPaths are now stored as a name + substring instead of one giant name, which in practice will improve performance and memory while manipulating them. Also the package table of soft referenced packages is now stored as FNames instead of FStrings as these packages names will already be in the name table due to the AssetRegistry
Remove automatic support for loading Objectpaths starting with engine-ini:, as it was only partially supported and is very outdated. ResolveIniObjectsReference can still be called manually
Changed TPersistentObjectPtr and TLazyObjectPtr to be structs instead of classes
Change UnrealHeaderTool to read configuration such as StructsWithNoPrefix out of inis instead of using a hardcoded list. Add support for TypeRedirects, which is used to make the old type names automatically remap to the new ones
Clean up FRedirectCollector to remove some of the functionality that is no longer used by the cooker, and disable tracking of redirects in standalone -game builds
Change 3567760 by Ben.Zeigler
Fix it so EngineTest can be cooked by moving some utility functions to EditorTestsUtilityLibrary and adding an EditorFunctionalTest. The core EngineTest module is safely runtime-only now and can run it's tests locally in windows cooked
Merge FuncTestManager into FunctionalTestModule to avoid confusion with FunctionalTestingManager UObject
Add EngineTestAssetManager and override the cook function to cook all maps with runtime functional tests
Change actor merging tests to be editor only, this stops them from cooking
Several individual tests crash on cooked builds, I started threads with the owners of those
Change 3575737 by Ben.Zeigler
#jira UE-48042 Change it so playing via PIE Standalone, multiprocess networked PIE and external cook launch on does not save temporary levels to UEDPC and instead prompts the user to save. This is how launch on works by default already, and this fixes cross level references/sequencer. The UEDPC code has been removed entirely.
As part of this change, connecting a -game client to a PIE server and vice versa is much more likely to work. You may still have game-side problems, look at UEditorEngine::NetworkRemapPath for an example of how to do the PIE prefix conversion
Remove advanced CreateTemporaryCopiesOfLevels option from sequencer capture, it has not been tested in multiple years and does not work with newer sequencer features
#jira UE-27124 Fix several possible crashes with changing levels while in PIE

UAT: Less spammy log and error output from UAT.
* Callstacks for AutomationExceptions are suppressed by default but still included in the log (the path to the log is noted in console output with the message from the exception).
* Add a mechanism for any exceptions to be caught and rethrown with additional lines of context (CommandUtils.AddContext()) that will be appended to the error output by UAT. Avoids decaying the exception type or masking the inner exception message while still adding additional information.
* AggregateExceptions resulting from exceptions on child threads are automatically unwrapped (full details are still appended to the log)
* Name of the calling function is not included in console output by default, but still included in the log.

Plugins: Allow plugins to specify a list of supported target platforms, which is propagated to any .uproject file that enables it.
This has several advantages over the per-module platform whitelist/blacklist:
* Platform-specific .uplugin files can now be excluded when staging other platforms. Previously, it was only possible to determine which platforms a plugin supports by reading the plugin descriptor itself. Now that information is copied into the .uproject file, so the runtime knows which plugins to ignore.
* References to dependent plugins from platform-specific plugins can now be eliminated.
* Plugins containing content can now be unambiguously disabled on a per-platform basis (having no modules for a platform does not confer that a plugin doesn't support that platform; now it is possible to specify supported platforms explicitly).
* The editor can load any plugins without having to whitelist supported editor host platforms.
UE4 targets which support loading plugins for target platforms can set TargetRules.bIncludePluginsForTargetPlatforms (true for the editor by default, false for any other target types). This defines the LOAD_PLUGINS_FOR_TARGET_PLATFORMS macro at runtime, which allows the plugin system to filter which plugins to look for at runtime.
Any .uproject file will be updated at startup to contain the list of supported platforms for each referenced plugin if necessary.

Plugins: Various fixes to settings for enabling plugins.
* Fix crash on startup when trying to disable a missing plugin (was keeping pointers to elements in the project's plugin reference array, which may be modified if a plugin is disabled).
* Revert fix to set PluginDescriptor.bRequiresBuildPlatform = true by default. This was the originally intended behavior, but it was accidentally defaulted to false during serialization unless specified in the .uplugin file. Many plugins may rely on this behavior (they may not declare asset classes otherwise, for example, which could result in loss of data), so change the default value to false instead. Also fixes popups to disable platform-specific plugins if platform SDKs are not installed.
* Fix plugins which are referenced but do not exist not showing the appropriate prompt to disable them.
Change 3540788 by Ben.Marsh
UBT: Add support for declaring custom pre-build steps and post-build steps from .target.cs files. Similarly to the custom build steps configurable from .uproject and .uplugin files, these specify commands which will be executed by the host platform's shell before or after a build. The following variables are expanded within the list of commands before execution: $(EngineDir), $(ProjectDir), $(TargetName), $(TargetPlatform), $(TargetConfiguration), $(TargetType), $(ProjectFile).
Example usage:
public class UnrealPakTarget : TargetRules
{
public UnrealPakTarget(TargetInfo Target) : base(Target)
{
Type = TargetType.Program;
LinkType = TargetLinkType.Monolithic;
LaunchModuleName = "UnrealPak";
if(HostPlatform == UnrealTargetPlatform.Win64)
{
PreBuildSteps.Add("echo Before building:");
PreBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");

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.
