Only use the recursion guard in async loading code when the event driven loader is enabled.
Change 3498112 by Ben.Marsh
UBT: Respect the option to not create debug info in the Android toolchain. This option is already being respected by the compiler, but the linker adds debug info of its own.
Change 3500239 by Robert.Manuszewski
Made sure the Super Class token stream is also locked when assembling Class token stream with async loading thread enabled. This to to prevent race conditions when loading BP classes.
Change 3500395 by Steve.Robb
Extra codegen savings when not in hot reload.
Change 3501004 by Steve.Robb
EObjectFlags now have constexpr operators.

Change 3504424 by Steve.Robb
New AllOf, AnyOf and NoneOf algorithms.
Change 3504712 by Ben.Marsh
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.
Change 3504808 by Ben.Marsh
UAT: Suppress P4 output when running a recursive instance of UAT.
Change 3505044 by Steve.Robb
Code generation improved for TCppClassType code.
Change 3505485 by Ben.Marsh
Fix deterministic cooking issue; always use a pseudo-random number stream when compiling a module.
Change 3505699 by Ben.Marsh
Plugins: Store the bEnabledByDefault flag exactly as it was read from disk rather than collapsing it to an absolute value based on the default for the location it was read from. This allows loading/saving plugin descriptors without any knowledge of whether they are game or engine plugins.
Change 3506055 by Ben.Marsh
UAT: Add a class to apply a log indent for the lifetime of an object (ScopedLogIndent), and use it to apply an indent to MegaXGE/ParallelExecutor output.
Change 3507745 by Robert.Manuszewski
Moved FSimpleObjectReferenceCollectorArchive and FSimpleObjectReferenceCollectorArchive to be internal archives used only by FReferenceCollector so that they are constructed only once per GC task instead of potentially multiple times per GC (as was the case with UDataTables and BlueprintGeneratedClasses).
Change 3507911 by Ben.Marsh
Plugins: Minor changes to plugin descriptors.
* Add a distinct setting for an unspecified EnabledByDefault setting in plugin descriptors.
* Add a function to IPlugin to determine the effective EnabledByDefault setting, based on where the plugin was loaded from.

Change 3514142 by Steve.Robb
MemoryProfiler2 added to generated solution.
Change 3516463 by Ben.Marsh
Plugins: Create a manifest for each PAK file containing all the plugin descriptors in one place. Eliminates need to recurse through directories and read separate multiple files in serial at startup, and allows reading all plugin descriptors with one read. The "Mods" directory is excluded from the manifest, since these are intended to be installed separately by the user.

Change 3520480 by Robert.Manuszewski
Improved assert message when the initial package read request was too small.
Change 3520590 by Graeme.Thornton
SignedArchiveReader optimizations
- Loads more stats
- Stop chunk cache worker from waking up continuously to poll for work. Only wake up when triggered by the archive reader
- Signed archive reader just yields when waiting for buffers to finish loading, rather than sleeping for some arbitrary amount of time
- Track the number of pending read requests in an atomic counter, to save having to lock the request queue to check for new entries
Change 3521023 by Graeme.Thornton
Remove spin from signed archive reader. Main thread waits on an event triggered by the chunk worker to indicate that new chunks are ready for processing

Move Linux SDL initialization into FLinuxPlatformApplicationMisc. Attempting to move functionality related to interactive applications (graphics, input, etc...) into a separate place, so it can ultimately be moved out of Core.
Change 3524741 by Ben.Marsh

Change 3525399 by Ben.Marsh
UGS: Use the default Perforce server port when opening P4V if there is not one set in the environment.

Change 3526453 by Ben.Marsh
UGS: Do not generate project files when syncing precompiled binaries.
Change 3527045 by Ben.Marsh
Fix hot reload generating import libraries without DLLs. Now that they are produced by separate actions by default, it was removing DLLs from the action graph due to the bSkipLinkingWhenNothingToCompile setting.
Change 3527420 by Ben.Marsh
UGS: Add additional search paths for UGS config files, and fix a few cosmetic issues (inability to display ampersands in tools menu, showing changelist -1 when running a tool without syncing).
Config files are now read from:
Engine/Programs/UnrealGameSync/UnrealGameSync.ini
Engine/Programs/UnrealGameSync/NotForLicensees/UnrealGameSync.ini
If a project is selected:
<ProjectDir>/Build/UnrealGameSync.ini
<ProjectDir>/Build/NotForLicensees/UnrealGameSync.ini
If the .uprojectdirs file is selected:
Engine/Programs/UnrealGameSync/DefaultProject.ini
Engine/Programs/UnrealGameSync/NotForLicensees/DefaultProject.ini
Change 3528063 by Ben.Marsh
Fix non-thread safe construction of FPluginManager singleton. Length of time spent in the constructor resulted in multiple instances being constructed at startup, making the time to enumerate plugins on slow media significantly worse.

Fixed lazy object pointers not being updated for streaming sub-levels in PIE. Fixed lazy pointers returning object that is still being loaded which could lead to undefined behavior when client code started modifying the returned object.
#jira UE-44996
Change 3530241 by Ben.Marsh
UAT: Only pass -submit or -nosubmit to child instances of UAT if they were specified on the original command line. BuildCookRun uses this flag to determine whether to submit, rather than just whether to allow submitting, so we shouldn't pass an inferred value.
Change 3531377 by Ben.Marsh
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.

Change 3539775 by Ben.Marsh
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)");
PostBuildSteps.Add("echo After building!");
PostBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");
}
}
}

BuildGraph: Improved tracing for error messages. All errors are now propagated as exceptions, and are tagged with additional context information about the task currently being run.
For example, throwing new AutomationException("Unable to write foo.txt") from SetVersionTask.Execute is now displayed in the log as:
ERROR: Unable to write to foo.txt
while executing <SetVersion Change="0" CompatibleChange="0" Branch="Unknown" Promoted="True" />
at Engine\Build\InstalledEngineBuild.xml(91)
(see D:\P4 UE4\Engine\Programs\AutomationTool\Saved\Logs\UAT_Log.txt for full exception trace)

UAT: Simplify logic for staging code, and add validation against shipping files in restricted folders.
* Added a new SystemNonUFS type for staged files, which excludes files from being remapped or renamed by the platform layer.
* Replaced the DeplyomentContext.StageFiles() function with simpler overloads for particular use cases (options for remapping are replaced with the SystemNonUFS file type)
* Config entries in the [Staging] category in DefaultGame.ini file allow remapping one directory to another, so restricted content can be made public in packaged builds (Example syntax: +RemapDirectory=(From="Foo/NoRedist", To="Foo"))
* An error is output if any restricted folder names other than the output platform are in the staged output.

#jira UE-45171 - Fix C++ compilation failures during packaging caused by nativizing a Blueprint that overrides a native function with a 'TSubclassOf' parameter or return value.

Change 3461210 by Phillip.Kavan
#jira UE-44505 - Fix occasional Blueprint editor crashes that could occur while rebuilding the context menu from the action registry.
Change summary:
- Modified FBlueprintActionDatabase::FActionRegistry to use an FObjectKey as the key type. This allows us to test entries for UObject validity before rebuilding context menu items based on the action database.
- Changed FBlueprintActionInfo::CachedOwnerClass to be a TWeakObjectPtr rather than a raw UClass* since it's based on the ActionOwner, which could potentially become invalid after the OwnerClass has been cached.
- Modified FBlueprintActionDatabase::RefreshAssetActions() to exclude World assets if the WorldType is not EWorldType::Editor. This eliminates an issue with unreferenced "inactive" GC'd world objects being left in the BP action registry after cooking, at which point the keys could become invalid.
- Added FBlueprintActionDatabase::DeferredRemoveEntry() to allow for scheduling removal of entries from outside of the database if they are known to be invalid.
- Modified FBlueprintActionDatabase::Tick() to handle deferred entry removals.
- Modified FBlueprintActionMenuBuilder::RebuildActionList() to both test actions for validity before building menu items and schedule removal of invalid actions on the next tick.
Notes:
- Alternatively we could just include UObject keys in the database's AddReferencedObject impl, but that would then prevent objects from ever being GC'd if they are not explicitly removed. For most entries the action database takes the approach of explicitly removing entries via delegate when the UObject is destroyed, so I chose to use a TWeakObjectPtr instead so that any entries that may not be getting explicitly removed via delegate will now simply become invalidated if the UObject key is GC'd due to not being referenced. I also set it up to clean and remove any entries (along with any associated node spawners) that are found to be invalid the next time we open the BP editor.

#jira UE-45140 Convert iterative cooking to use the Asset Registry as it's only mode, remove old hash and timestamp versions. This allows deleting the entire PackageDependencyInfo module
Change the asset registry iteration to not compute a hash at all, and instead store the script package guids in it's cache.

#jira UE-45477 - Fix an EDL assertion on load in a nativized build with one or more Actor subobjects instanced via the EditInlineNew UI in the BP class defaults property editor.
Change summary:
- Modified FEmitDefaultValueHelper::OuterGenerate() to emit code to construct/initialize instanced subobject values that do not have the RF_DefaultSubObject flag set, and also to recursively handle nested subobjects for those values.
- Modified FEmitDefaultValueHelper::HandleInstancedSubobject() to alternatively emit a 'NewObject' assignment statement rather than a 'CreateDefaultSubobject' statement if only RF_ArchetypeObject is set on the source object value.

#jira UE-45517 - Fix a regression in which dragging UMG widgets around in the designer view results in redundantly-compounded BP class properties and context menu actions.
Change summary:
- Modified SDesignerView::ClearDropPreviews() to move the widget that was removed from the tree into the transient package. This ensures that FWidgetBlueprintCompiler::CreateClassVariablesFromBlueprint() won't pick them up.
- Modified SDesignerView::ProcessDropAndAddWidget() to also consider any widgets not added to the 'DropPreviews' array as being transient (i.e. also move them into the transient package since they were not added to the tree).

Change summary:
- Modified FEdGraphUtilities::PostProcessPastedNodes() to ensure() on a NULL pin entry; this will allow execution to continue while still alerting us since it is an unexpected result. Also added an 'else' case to then remove the NULL entry so that PostPasteNode() implementations don't all have to guard against NULL pin entries. When the node is reconstructed, the NULL entry will be replaced with the correct pin initialized to its default values.
- Modified UEdGraphPin::ImportTextItem() to add some additional logging to parse error cases when importing pin properties from source T3D text. Hopefully this gives us more information when this is encountered in the future.

Engine: Introduced a new version of UEngine::GetWorldFromContextObject which takes an enum specifying the behavior on failures and updated all existing uses
The new version intentionally does not have a default value for ErrorMode, callers need to think about which variant of behavior they want:
- ReturnNull: Silently returns nullptr, the calling code is expected to handle this gracefully
- LogAndReturnNull: Raises a runtime error but still returns nullptr, the calling code is expected to handle this gracefully
- Assert: Asserts, the calling code is not expecting to handle a failure gracefully
- Deprecated UEngine::GetWorldFromContextObject(object, boolean) and changed the default behavior for the deprecated instances to do LogAndReturnNull rather than Assert, based on the real-world call pattern
- Introduced GetWorldFromContextObjectChecked(object) as a shorthand for passing in EGetWorldErrorMode::Assert
- Made UObject::GetWorldChecked() actually assert if it would return nullptr (under some cases the old function could silently return nullptr while reporting bSupported = true, so it neither ensured nor checked)
- Fixed a race condition in the 'is implemented' bookkeeping logic in GetWorld()/GetWorldChecked() by confining it to the game thread and added a check() to ImplementsGetWorld() to make it clear that it only works on the game thread
The typical recommended call pattern is to use something like:
if (UWorld* World = GEngine->GetWorldFromContextObject(WorldContextObject, EGetWorldErrorMode::LogAndReturnNull))
{
... Do something with World
}
Handling the failure case but requesting a log message (with BP call stack printed out) if it failed. This is now also the default behavior for old calls to UEngine::GetWorldFromContextObject(Object) (using the default value of bChecked=true), which is a behavior change but it matches how the function was being used in practice; the vast majority of call sites actually expected it to potentially fail and handled the nullptr case gracefully; very few places used the return value unguarded and wanted it to assert when passed a nullptr.

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
#jira UE-43458
Change 3499953 by Michael.Noland
Core: Created a variant of ensure that does runtime error logging without stopping in the debugger and some related functions that print a warning or error and may trigger a BP callstack (under the same rules as FFrame::KismetExecutionMessage)
- These are WIP and the API may change in the future, but are being used to fix various crashes found by fuzzing BP exposed functions

Physics: Prevented a crash in UTraceQueryTestResults::AssertEqual when passed in nullptr for Expected
Change 3499993 by Michael.Noland
Blueprints: Added validation when renaming variables, functions, components, multicast delegates, etc... to prevent names from containing some unacceptable characters
- This validation only kicks in when trying to rename an item, so bad names in existing content are 'grandfathered in'
- These bad names can cause bugs when working with content that contains these characters (e.g., names that contain a period cannot be found via FindObject<T>)
- Currently only . is banned, but eventually we may expand it to include all of INVALID_OBJECTNAME_CHARACTERS
Change 3500009 by Michael.Noland
Blueprints: Made the fuzzer skip classes declared in UnrealEd for now (some of the exposed methods change global state that can cause other tests to fail as the fuzzer isn't particularly sandboxed ATM)

Change 3501457 by Phillip.Kavan
#jira UE-46054 - Fix crash when launching a packaged build that includes a nativized Blueprint instance with a ChildActorComponent instanced via an AddComponent node.
Change summary:
- Removed UK2Node_AddComponent::PostDuplicate(). This eliminates the creation of redundant component templates that were being unnecessarily created during the Blueprint duplication that precedes the nativization pass.
- Modified SMyBlueprint::OnDuplicateAction() to call MakeNewComponentTemplate() in response to a graph duplication action within the same Blueprint context (replaces previous UK2Node_AddComponent::PostDuplicate() impl).
- Modified FEmitDefaultValueHelper::HandleSpecialTypes() to force AddComponent-based CAC-owned template objects in the emitted codegen to use the UDynamicClass as the Outer when instancing. This matches what we already do for SCS-based CAC-owned template objects - that logic was added in CL# 3270456, and this matches up with FBlueprintNativeCodeGenModule::FindReplacedNameAndOuter(), where we specifically handle CAC-owned template objects.

MAJOR FEATURES + CHANGES
==========================
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.
