f3cdc69725 Slate - Adding improvements to the widget reflector so that we can tell if a zero size widget is present, as it may have padding around it, so now a line will appear if it's zero sized, rather than nothing.

  MAJOR FEATURES & CHANGES
============================

Change 4247640 by Daniel.Lamb

	BuildPatchTool: PackageChunks: Fixed issue with filenames not being set for chunkdbs in particular cases where the chunkdbs were small.

Change 4247246 by Leigh.Swift

	BuildPatchTool: Adding support to BPT PackageChunks to filter by tagsets, and also split chunkdb output by them too.

Change 4173518 by Wes.Fudala

	WebBrowser: Adding support to enable allowing net security expirations.

Change 4102451 by Leigh.Swift

	BuildPatchTool: PackageChunks: Adding tool mode JSON output for listing created chunkdb files.

Change 4099951 by Leigh.Swift

	BuildPatchTool: PackageChunks: Adding PrevManifestFile commandline support to BPT PackageChunks mode, allowing us to generate chunkdbs that only cover data required to perform an update.

Change 4051406 by Leigh.Swift

	BuildPatchServices: Update default number of simultaneous downloads for an installer to 16 which is now well proven in the wild.

Change 4036807 by Leigh.Swift

	BuildPatchServices: Added new message type for receiving updates about which files have been touched by the installation.
	BuildPatchServices: Cloud enumeration is now threaded to improve speed.

Change 4036477 by Richard.Fawcett

	Thirdparty: AWSSDK: Update AWS SDK to version 3.3 as speculative fix for object is used after being disposed error.

	Confirmed this exception is being raised from within the AWS SDK, and _not_ in Epic code.
	Advice by Amazon on AWS forums for people experiencing this exception is always to update to the latest version of the SDK in the first instance.

Change 3922493 by Justin.Sargent

	Runtime: Added shortcircuit support to the ExpressionParser. More documentation to come.
	AgreementExpressionEvaluator has been updated to use the shortcircuit logic so it now processes expressions lef to right as expected in all cases.
	AgreementExpressionEvaluator was also updated to perform evaluation as a two pass system. The tow pass solution prevents over prompting eulas in certain scenarios where the expression would ultimately resolve true without them.

Change 3983713 by Barnabas.McManners

	BuildPatchServices: Fix for verification logging error counts for unique runs. Solved the issue by using an external cache of the errors encountered each run to deduct from the total. Reporting only the delta.

Change 3966915 by Wes.Fudala

	WebBrowser: CEF: Potential fix for a rare issue encountered when we attempting to release resources outside of the game thread.

Change 3955168 by Justin.Sargent

	BuildPatchServices: Updated primary messaging of overall install status to now display Updating when patching an existing installation rather than Installing.

Change 3954610 by Leigh.Swift

	BuildPatchServices: Fixing issue with Cloud Chunk Source which would erroneously conclude that it needed to re-download a chunk due to external system failure.

	There is now an explicit concept of 'lost chunk' which is tracked and bubbled up by the system errors that cause the loss in the first place, so that each source knows exactly when it should be required to retrieve a chunk that it had already retrieved previously. Being explicit, these lost chunks can also now contribute to the total download required stat.
	Also fixing some tracking that was missing to update the total download required stat if a local Install Chunk Source failed to load data from the files on disk and so these chunks needed to be additionally downloaded.

Change 3947928 by Chad.Garyet

	UAT: Changing commandutils to attempt to find the Win8.1sdk signtool before the win10 one.  There's currently a bug related to vs2017/server2012r2/win10sdk signtool that causes it to exit with an undefined error when signing from a service account.  Using the win8.1sdk circumvents this issue.

Change 3942776 by Rob.Cannaday

	Http: Fix for Mac sending up duplicate header strings

Change 3940306 by Leigh.Swift

	BuildPatchServices: Refactor to isolate CoreUObject dependency and be able to compile out usage.

Change 3936655 by Justin.Sargent

	Slate: Changed the invalid fontcache ensure in ShapedTextCache from always to only once to reduce ensure spamChange 3917840 by Leigh.Swift

	BuildPatchTool: DiffManifests mode now also saves info for New, Removed, Changed, and Unchanged file to the output json file.

Change 3911756 by Justin.Sargent

	WebBrowser: SWebBrowserView now ensures that it has a valid pointer to it's parent window in it's onpaint to avoid issues with the first frame being scaled incorrectly due to not being able to access the parent windows dpi scaling.

Change 3906670 by Justin.Sargent

	Slate: Change the ShapedTextCache to hold a weakptr to the Slate FontCache instead of a reference. This will allow it to detect if the FontCache has become invalid since it was linked with the ShapedTextCache, thus making it able to avoid crashing.

Change 3889008 by Justin.Sargent

	StandaloneRenderer: Made the SlateD3DRenderingPolicy more resilient to graphics device errors.

Change 3886969 by Justin.Sargent

	StandaloneRenderer:Changed SlateD3DConstantBuffer to no longer check on a D3DDevice failure and instead soft fail, so the application can go through the process of attempting to re-establish the D3DDevice.

Change 3886960 by Justin.Sargent

	WebBrowser: Made CEFWebBrowserWindow more resilient to issues with creating textures.

Change 3855821 by Barnabas.McManners

	BuildPatchServices: Added logging of the configuration to the start of all installs.

Change 3839245 by Wes.Fudala

	WebBrowser: Adding support for web browser drag regions.  These are areas of a page tagged with -webkit-app-region: drag or -webkit-app-region: no-drag.  The application can now pass a handler function to the browser to handle window drag events.  This handler will be called if the browser detects mouse drag events inside of a tagged drag region.

Change 3835225 by Jacob.Hedges

	Slate: Fix for SScrollBarTrack size issue

Change 3824320 by Wes.Fudala

Change 3807662 by Barnabas.McManners

	BuildPatchServices: Broke down build verification errors into 4 new cases.

Change 3805698 by Leigh.Swift

	BuildPatchServices: Speculative fixes for Unit test crashes / failures.

Change 3804175 by Wes.Fudala

	ThirdParty: CEF: Adding browser locale pak files for es-MX, and es-ES as the typical mapping/fallback does not seem functional on mac browser.  They are copies of es_419 and es respectively.

Change 3786628 by Leigh.Swift

	WebBrowser: Exposing ability to customise tool tip widgets produced from SWebBrowserView.

Change 3775678 by Richard.Fawcett

	BuildPatchServices: Allow a Prerequisite install only mode.

Change 3774365 by Justin.Sargent

	BuildPatchServices: Updated Build Stat report that is logged after every installation to use FText::AsMemory instead of the UnitConversion logic, and now it outputs multiple unit types for convenience.

	BuildPatchServices: Hooking up disk chunk store operation states to the installer statistics.
	BuildPatchServices: Memory chunk store statistics fix for booted chunks that have been reloaded.

Change 3756320 by Rob.Cannaday

	Http: Add default headers added to every HTTP request.

Change 3741274 by Wes.Fudala

	WebBrowser: Release CEF related references prior to CEF shutdown.

Change 3738003 by Leigh.Swift

	BuildPatchServices: Fix-ups for install stats when failures are occurring
	NumFilesOutdated now only set on first run, so it is not set to the number of files that are retried.
	Total downloaded data and total download requirement stats fixed up for runtime as well as final values.
	Initial chunk counters now only set for first run.
	Moving the GetBytesDownloaded api from cloud source to download service so that it correctly accumulates.
	InstallSource was multiply attempting, and counting, recycle failures, throwing that stat out of proportion.

Change 3729851 by Barnabas.McManners

	BuildPatchServices: Changed the installer's MoveFile method to default to not retry. We currently only have uses of move file which already handle retry.

Change 3725611 by Leigh.Swift

	Core: FText::AsMemory - Fix for numerical edges.
	Added unit tests to check all edges up to full uint64 range.

Change 3721926 by Justin.Sargent

	ThirdParty: LibCurl update performed by Simon Tourangeau.
	We now have 100MB/sec download speed with libcurl on Win64, compared to 3MB/sec originally

Change 3700670 by Michael.Trepka

	SlateReflector: Fixed mouse click highlighting in Widget Reflector's Demo Mode in high DPI

Change 3684747 by Leigh.Swift

	BuildPatchTool: Fix file ignore list to parse using platform agnostic method.

Change 3643038 by Michael.Trepka

	Core: Don't defer Cocoa calls in FMacWindow Show and Hide to make sure both actions complete before we exit these functions. This solves the problem with the blocks being called after window was destroyed.

Change 3639692 by Michael.Trepka

	Fixes for a couple of issues found by address sanitizer

Change 3625568 by Leigh.Swift

	BuildPatchServices: Fixing numerical limits problem with double -> uint64 in FStatsCollector::SecondsToCycles().

Change 3617948 by Leigh.Swift

	#jira UE-53445 SceneCaptureComponent2D hidden actors always disabled in details layout

Change 3828444 by Anthony.Bills

	Add LXC container script for building third party libraries.

	The intention is that this should become the only way to rebuild the third party libraries that require system dependencies not included in the cross-compile toolchain and also to rebuild the toolchains. Other third party libraries without any system dependencies could be rebuilt via the cross-compile toolchains/UBT.

	This script has been tested running on CentOS 7 and Ubuntu 17.10.

	Buy default the x86 and x86_64 builds will be built against a CentOS 6 container (and targeting glibc 1.12) and the aarch64 and armhf builds will use an Ubuntu Ubuntu Trusty (14.04) but this is not yet complete.

Change 3887093 by Anthony.Bills

	Add bundled mono binary for Linux.

	- Unify some of the script structure across Mac and Linux.
	- This currently uses the same mono C# assemblies as Mac to keep the additional source size down.
	- If the Mac mono version is updated, the Linux version will also need to be updated to match the same mono git revision.
	- The system version of mono can still be used by setting the UE_USE_SYSTEM_MONO env var to 1.

Change 4003226 by Michael.Dupuis

	Refactored StaticMeshInstancing to now use a command buffer to communicate with the GPU to prevent concurent access issues. It's mostly used in Editor or if runtime changes occur, otherwise the data is built and send to the GPU directly without keeping CPU copy.
	Changed how the density scaling was applied to be more optimal
	Removed UseDynamicInstanceBuffer as the concept is now irrelevant

Change 3833097 by Jamie.Dale

	Localization Pipeline Optimization

	Manifest/Archives:
	Added FLocKey to keep an immutable string and its hash. This is used in several places within manifests and archives to minimize string hashing. FLocTextHelper also now take these in its API.
	This also fixes some places where manifests were being iterated by key rather than source string (as this was causing redundant work).

	Portable Object:
	Cleaned up a lot of redundant code, changed things to use FLocKey, and simplified a lot of string manipulation to use algorithms instead (which proved to be faster).

	Asset Gathering:
	Optimized the way garbage collection runs while gathering from assets so that we avoid purging assets that we still need to gather from (or are still active dependencies). This also sorts the assets so that we can try and evict dependencies from memory as soon as possible (in much the same way that the cooker does).

	Automation:
	The gather commandlet can now take multiple configs to process. This is used by automation to avoid starting the editor several times (which can save a significant amount of start-up overhead).

  MAJOR FEATURES & CHANGES
============================

Change 3805828 by Gil.Gribb

	UE4 - Fixed a bug in the lock free stalling task queue and adjusted a comment. The code is not current used, so this is not actually change the way the code works.

Change 3806784 by Ben.Marsh

	UAT: Remove code to compile UBT when using UE4Build. It should already be compiled as a dependency of UAT.

Change 3807549 by Graeme.Thornton

	Add a cook timer around VerifyCanCookPackage. A licensee reports this taking a lot of time so it'll be good to account for it.

Change 3807727 by Graeme.Thornton

Change 3808221 by Steve.Robb

	GitHub #4307 - Made GetModulePtr() thread safe by not using GetModule()

	^ I'm not convinced by how much thread-safer this is really, but it's tidier anyway.

Change 3809233 by Graeme.Thornton

	TBA: Misc changes to text asset commandlet
	 - Rename mode to "loadsave"

	See: https://udn.unrealengine.com/questions/376978/aitask-blueprint-nodes-disappear-when-their-module.html

	#jira UE-53089

Change 3820358 by Ben.Marsh

	PR #4358: Incredibuild use ShowAgent by default (Contributed by projectgheist)


Change 3822594 by Ben.Marsh

	UAT: Improvements to log file handling.

	- Always create log files in the final location, rather than writing to a temp directory and copying in later.
	- Now supports -Verbose and -VeryVerbose for increasing log verbosity, rather than -Verbose=XXX.
	- Keep a backlog of log output before the log system is initialized, and flush it to the log file once it is.
	- Allow buildmachines to specify the uebp_FinalLogFolder environment variable, which is used to form paths for display. When build machines copy log files elsewhere after UAT finishes (eg. a network share), this allows error messages to display the right location.

Change 3823695 by Ben.Marsh

	UGS: Fix issue where precompiled binaries would not be shown as available for a change until scrolling the last submitted code change into the buffer (other symptoms, like de-focussing the main window would cause it to go back to an unavailable state, since the changes buffer was shrunk).

	Now always queries changes up to the last change for which zipped binaries are available.

Change 3823845 by Ben.Marsh

	UBT: Exclude C# projects for unsupported platforms when generating project files.

Change 3824180 by Ben.Marsh

	UGS: Add an option to show changes by build machines, and move the "only show reviewed" option in there too (Options > Show Changes).

	#jira

Change 3825777 by Steve.Robb

	Fix to return value of StringToBytes.

Change 3825810 by Ben.Marsh

	UBT: Reduce length of include paths for MSVC toolchain.

Change 3825822 by Robert.Manuszewski

	Optimized PIE lazy pointer fixup. Should be up to 8x faster now.

Change 3826734 by Ben.Marsh

	Remove code to disable TextureFormatAndroid on Linux. It seems to be an editor dependency.

Change 3827730 by Steve.Robb

	Try to avoid decltype(auto) if it's not supported.

	See: https://udn.unrealengine.com/questions/395644/build-417-with-c11-on-linux-ttuple-errors.html

Change 3827745 by Steve.Robb

	Initializer list support for TMap.

Change 3827770 by Steve.Robb

	GitHub #4399 : Added a CONSTEXPR qualifiers to FVariant::GetType()

	#jira UE-53813

Change 3829189 by Ben.Marsh

	UBT: Now always writes a minimal log file. By default, just contains the regular console output and any reasons why actions are outdated and needed to be executed. UAT directs child UBT instances to output logs into its own log folder, so that build machines can save them off.

Change 3830444 by Steve.Robb

	BuildVersion and ModuleManifest moved to Core, and parsing of these files reimplemented to avoid a JSON library.
	This should be revisited when Core has its own JSON library.

Change 3830718 by Ben.Marsh

	Fix incorrect group name being returned by FStatNameAndInfo::GetGroupName() for stat groups.

	The editor populates the viewport stats list by calling this for every registered stat and stat group (via FLevelViewportCommands::HandleNewStatGroup). The menu entry attempts to show the stat name with STAT_XXX stripped from the start as the menu item label, with the free-form text description as a tooltip.

	For stat groups, the it would previously just return the stat group name as "Groups" (due to the raw naming convention of "//Groups//STATGROUP_Foo//..."). Since this didn't match the expected naming convention in FLevelViewportCommands::HandleNewStat (ie. STAT_XXX or STATGROUP_XXX), it would fail to add it.

	When the first actual stat belonging to that group is added, it would add a menu entry for the group based on that, but the stat description no longer makes sense as a tooltip for the group. As a result, all the editor tooltips were junk.

	#jira UE-53845

Change 3831064 by Ben.Marsh

	Fix log file contention when spawning UBT recursively.

Change 3832654 by Ben.Marsh

	UGS: Fix error panel not being selected when opened, and weird alignment/color issues on it.

Change 3832680 by Ben.Marsh

	UGS: Fix failing to detect workspace if synced to a different stream. Seems to be a regression caused by recent P4D upgrade.

Change 3832695 by Ben.Marsh

	UGS: Invert the options in the 'Show Changes' submenu for simplicity.

Change 3833528 by Ben.Marsh

	UAT: Script to rewrite source files with public include paths relative to the 'Public' folder. Usage is: RebasePublicIncludePaths -UpdateDir=<Dir> [-Project=<Dir>] [-Write].

Change 3833543 by Ben.Marsh

	UBT: Allow targets to opt-out of having public include paths added for every dependent module. This reduces the command line length when building a target, which has recently become a problem with larger games (due to Microsoft's compiler embedding the command line into each object file, with a maximum length of 64kb). All engine modules are compiled with this enabled; games may opt into it by setting bLegacyPublicIncludePaths = false; from their .target.cs, as may individual modules.

Change 3834354 by Robert.Manuszewski

	Archetype pointer will now be cached to avoid locking the object tables when acquiring its info. It should also be faster this way regardless of any locks.

	#jira UE-52035

Change 3834400 by Robert.Manuszewski

	Fixing crash on exit caused by cached archetypes not being cleaned up before static exit cleanup.

	#jira UE-52035

Change 3834947 by Steve.Robb

	USE_FORMAT_STRING_TYPE_CHECKING removed from FMsg::Logf and FMsg::Logf_Internal.

Change 3835004 by Ben.Marsh

	Fix code that relies on dubious behavior of requiring referenced "include path only" modules having their _API macros set to be empty, even if the module is actually implemented in a separate DLL.

Change 3835340 by Ben.Marsh

	Fix errors making installed build from directories with spaces in the name.

Change 3835972 by Ben.Marsh

	UBT: Improved diagnostic message for targets which don't need a version file.

Change 3836019 by Ben.Marsh

	UBT: Fix warnings caused by defining linkage macros for third party libraries.

Change 3836269 by Ben.Marsh

	Fix message box larger than the screen height being created when a large number of modules are incompatible on startup.

Change 3836543 by Ben.Marsh

	Enable SoundMod plugin on Linux, since it's already supported through the editor.

Change 3836546 by Ben.Marsh

	PR #4412: fix type mismatch (Contributed by nakapon)


Change 3836805 by Ben.Marsh

	Fix commandlet to compile marketplace plugins.

Change 3836829 by Ben.Marsh

	UBT: Fix ability to precompile plugins from installed engine builds.

Change 3837036 by Ben.Marsh

	UBT: Write the previous and new contents of intermediate files to the log if they change. Makes it easier to debug unexpected rebuilds.

Change 3837037 by Ben.Marsh

	UBT: Fix engine modules having inconsistent definitions depending on whether modules are only referenced for their include paths vs being linked into a binary (due to different _API macro).

Change 3837040 by Ben.Marsh

	UBT: Remove code that initializes members in ModuleRules and TargetRules objects before the constructor is run. This is no longer necessary, now that the backwards-compatible default constructors have been removed.

Change 3837247 by Ben.Marsh

	UBT: Remove UELinkerFixups module, now that plugins and precompiled modules do not require hacks to force initialization (since they're linked in as object files).

	Encryption and signing keys are now set via macros expanded from the IMPLEMENT_PRIMARY_GAME_MODULE macro, via project-specific macros added in the TargetRules constructor.

Change 3837262 by Ben.Marsh

	UBT: Set whether a module is an engine module or not via a default value for the rules assembly. All non-program engine and enterprise modules are created with this flag set to true; program targets and modules are now created from a different assembly that sets it to false. This removes hacks from UEBuildModule needed to adjust behavior for different module types based on the directory containing the module.

	Also add a bUseBackwardsCompatibleDefaults flag to the TargetRules class, also initialized to a default value from a setting passed to the RulesAssembly constructor. This controls whether modules created for the target should be configured to allow breaking changes to default settings, and is set to false for all engine targets, and true for all project targets.

Change 3837343 by Ben.Marsh

	UBT: Remove the OverrideExecutableFileExtension target property. Change the only current use for this (the MayaLiveLinkPlugin target) to use a post build step to copy the file instead.

Change 3837356 by Ben.Marsh

	Fix invalid character encodings.

Change 3837727 by Graeme.Thornton

	UnrealPak: KeyGenerator: Only generate prime table when required, not all the time

Change 3837823 by Ben.Marsh

	UBT: Output warnings and errors when compiling module rules assembly in a way that allows them to be double-clicked in the Visual Studio output window.

Change 3837831 by Graeme.Thornton

	UBT: When parsing crypto settings, always load legacy data first, then allow the new system to override it. Provides the same key backwards compatibility that the editor settings class gives

Change 3837857 by Robert.Manuszewski

	PR #4404: Make FGCArrayPool singleton global instead of per-CU (Contributed by mhutch)


Change 3837943 by Robert.Manuszewski

	PR #4405: Fix FGarbageCollectionTracer (Contributed by mhutch)


Change 3838451 by Ben.Marsh

	UBT: Fix exceptions thrown on a background thread while caching C++ includes not being caught and logged correctly. Now captures exceptions and re-throws on the main thread.

	#jira UE-53996

Change 3839519 by Ben.Marsh

	UBT: Simplify configuring bPrecompile and bUsePrecompile settings for modules. Each rules assembly can now be configured as installed, which defaults the module rules it creates to use precompiled data.

Change 3843790 by Graeme.Thornton

	UnrealPak: Log the size of all encrypted data

Change 3844258 by Ben.Marsh

	Fix plugin compile failure when created via new plugin wizard. Passing -plugin on the command line is unnecessary, and is now reserved for packaging external plugins for the marketplace.

	Also extend the length of time that the error toast stays visible, and don't delete the plugin on failure.

	#jira UE-54157

Change 3845796 by Ben.Marsh

	Workaround for slow performance of String.EndsWith() on Mono.

Change 3845823 by Ben.Marsh

	Fix case sensitive matching of platform names in -TargetPlatform=X argument to BuildCookRun.

	#jira UE-54123

Change 3845901 by Arciel.Rekman

	Linux: fix crash due to lambda lifetime issues (UE-54040).

	- The lambda goes out of scope in FBufferVisualizationMenuCommands::CreateVisualizationCommands, crashing the editor if compiled with a recent clang (5.0+).

	(Edigrating 3819174 to Dev-Core)

Change 3846439 by Ben.Marsh

	Revert CL 3822742 to always call Process.WaitForExit(). The Android target platform module in the editor spawns ADB.EXE, which inherits the editor's stdout/stderr handles and forks itself. Process.WaitForExit() waits for EOF on those pipes, which never occurs because the forked process never terminates.

	Proper fix is probably to have the engine explicitly duplicate stdout/stderr handles for new pipes to output process, but too risky before copying up to Main.

Change 3816608 by Ben.Marsh

	UBT: Use DirectoryReference objects for all include paths.

Change 3816954 by Ben.Marsh

	UBT: Remove bIncludeDependentLibrariesInLibrary option. This is not widely supported by platform toolchains, and is not used anywhere.

Change 3816986 by Ben.Marsh

	UBT: Remove UEBuildBinaryConfig; UEBuildBinary objects are now just created directly.

Change 3816991 by Ben.Marsh

	UBT: Deprecate PlatformSpecificDynamicallyLoadedModules. We no longer have any special behavior for these modules.

Change 3823090 by Ben.Marsh

	UAT: Improve logging for child UAT instances.

	- Calling RunUAT now requires an identifier for prefixing into the parent log, which is also used to determine the name of the log folder.
	- Stdout is no longer written to its own output file, since it's written to the parent stdout, the parent log file, and the child log file anyway.
	- Log folders for child UAT instances are left intact, rather than being copied to the parent folder. The derived names for the copied names were confusing and hard to read.
	- Output from UAT is no longer returned as a string. It should not be parsed anyway (but may be huge!). ProcessResult now supports running without capturing output.

Change 3826082 by Ben.Marsh

	UBT: Add a check to make sure that all modules that are precompiled are correctly marked to enable it, even if they are part of the build target.

Change 3827025 by Ben.Marsh

	UBT: Move the compile output directory into a property on the module, and explicitly pass it to the toolchain when compiling.

Change 3829927 by James.Hopkin

	Made HTTP interface const correct

Change 3833533 by Ben.Marsh

	Rewrite engine source files to base include paths relative to the "Public" directory. This allows reducing the number of public include paths that have to be added for engine modules.

Change 3835826 by Ben.Marsh

	UBT: Precompiled targets now generate a separate manifest for each precompiled module, rather than adding object files to a library. This fixes issues where object files from static libraries would not be linked into a target if a symbol in them was not referenced.

Change 3835969 by Ben.Marsh

	UBT: Fix cases where text is being written directly to the console rather than via logging functions.

Change 3837777 by Steve.Robb

	Format string type checking added to FOutputDevice::Logf.
	Fixes for those.

Change 3838569 by Steve.Robb

	Algo moved up a folder.

Change 3780878 by Nick.Darnell

	UMG - Providing more information when the compile fails to find a bindable widget.


Change 3780855 by Gil.Gribb

	UE4 - Fixed a linear search in EDL that caused performance problems for very large maps. Saves half the load time in FN-BR.


Change 3780803 by Thomas.Sarkanen

	Dont create animation tasks for skeletal meshes that have no anim instance

	This avoids some wasted work for non-animated attachments, such as pickaxes

	#jira FORT-61523 - Don't create anim worker tasks if no AnimBP


Change 3780741 by Yenal.Kal

	#jira FORT-60177

	Fixed the bug where the anim branching points (begin and end) may be triggered twice incorrectly.

Change 3780663 by Gil.Gribb

	UE4 - Batching for audio thread commands.


Change 3780466 by Ben.Marsh

	Add error matcher for generic Microsoft errors (eg. 'cl : Command line error D8049 : command line too long to fit in debug record')

Change 3779937 by Nick.Darnell

	UMG - Adding an accessor on UUserWidget to get the owning player state easier, since it's a common operation.

	#jira FORT-61666
	#tests none

Change 3779288 by Michael.Trepka

	Changed FMacConsoleOutputDevice::Serialize to use FString's GetNSString() instead of converting the string using FPlatformString::TCHARToCFString to make it safer in case of garbage text passed in Data

	#jira FORT-59762

Change 3779062 by Mike.Fricker

	Merged CL 3731188 and CL 3733311 from //UE4/Dev-Editor.

	----

	Improve responsiveness of Open Asset dialog.

	On large projects, there's a noticeable delay when opening and searching/filtering assets.

	Stopwatch measurements on my machine (seconds for ~122,000 assets):
		before	with this CL
	ctrl-P	1.4	0.45
	search	1.8	0.55

	CollectionManagerModule was the main culprit for search/filter slowness.

	Open Asset delay was due to filtering out plugin content. We were doing a lot of redundant work for what is essentially a read-only operation.

	 Reduced impact of dynamic vertex buffer RHI stall in D3D12
	 - In most cases we can avoid the stall if the vertex buffer has never been used before.
	 - Only when a buffer has an existing SRV do we need to stall.

	 - Also, delete copy and move constructors of FD3D12ResourceLocation. Moving or copying an instance of this class leads to double free crashes, so this is now a compile error rather than a runtime crash.

	This saves an average of 2ms frame time in a StW lastperftest replay, with r.screenpercentage 10.

Change 3772867 by Thomas.Sarkanen

	Nativization now correctly generates and builds code for "Client" builds

	Overall this is a bunch of hacks, but necessary for nativization to work at present. Once the cooker and UAT both have a concept of "Client" targets, this can be implemented properly.
	Instead of building to a "Client" directory, we build to "Game" for client-only platforms (like PS4, XboxOne)
	Also we need to add "Client" targets to the whitelist for the nativized assets plugin, as UBT still thinks it is building for "Client"

	Improvements to the Cpp backend to allow VC++ to compile nativized code more effectively

	Added a new scoped helper to wrap areas of the code in PRAGMA_DISABLE_OPTIMIZATION. This helps with functions that are large tables or long lists of initializations.
	Split anim node initialization up into functions, called from a seperate function dedicated to initializing anim nodes. This splits the 5k+ line constructor into mutiple smaller functions, which the compiler has no problems with.
	Overall (along with splitting up the anim BP into functions in the asset) this reduces compilation time for the worst-case compilation unit from ~11m 40s to ~2m 32s.

	Fixes to enable auto-nativization for animation blueprints

	For blend profiles in particular, I've added subobject support to the fake import table building for nativized assets:
	- In FEmitterLocalContext::FindGloballyMappedObject, if we dont find the referenced asset then we traverse the object's outer chain if it is a subobject. We add it to UsedObjectInCurrentClass if we find its outer.
	- Updated the structure used to build the fake import table to include a specified outer. Beforehand we assumed that all objects referenced by the import table were 'top-level'.
	- Updated the fake import table building code in FLinkerLoad::CreateDynamicTypeLoader() to use the new specified outer if found. This asserts if it couldnt find the outer in the already-parsed dependencies (as it reverse-iterates). If in the general case thius turns out to be a problem we can move this to a two-pass system.

	Disabled fast-path optimization when running a native anim BP, as native code is faster!

	UE4 - Downgraded a fatal error to a warning. Example: Found package without a linker, could find SceneComp in /Game/AIDirector/AIDirector_Fortnite, but somehow wasn't finished loading. This is a sort of cook mismatched caused by the fact that all PS4 cooks have server-only data in them.

Change 3742187 by Nick.Darnell

	Slate - Adding a new optional parameter to direct routing for the widgets under the cursor in Slate Application.  Essentially ProcessReply occasionally needs to know the widgets under the cursor, the previous implementation, just used the routing path, this results in missing sending mouse leave messages to widgets under the cursor when dragging begins, which often left things with hover effects in bad states.

	UMG - Finishing the ability to add a "Custom" method for Navigation.  Currently the editor implementation leaves me wanting, but it works for now.  You can put the name of a function to call (needs to match a signature that returns a UWidget).


Change 3740207 by Nick.Darnell

	Slate - Navigation attempts when the user claims they are doing custom or explicit, if those methods don't return a valid widget, we don't treat it like the attempt failed and fallback to default navigation methods.  Instead we use it as a trigger to indicate that no navigation should occur and treat it like a stop.

	Editor: Rewrote CallInEditor support and promoted it so it can be used on functions in any class, not just blueprints derived from AActor:

	- CallInEditor can now be used as a top-level keyword in the UFUNCTION() declaration (e.g., UFUNCTION(Category=CoolCommands, CallInEditor))
	- Now shows each function as a separate button, placed in the category associated with the function
	- The button strip entry is now searchable by function name or tooltip
	- Prevented operating on functions that have parameters or return values, which would crash before
	- Removed the duplicate copies of properties placed in the Blutility section
	- Added a scoped transaction around CallInEditor execution
	- Allowed functions to be marked as CallInEditor in addition to custom events (currently we don't allow editing category or tooltip on custom events...)

	3rd attempt for branch name checking in engine code hacks

Change 3689050 by David.Ratti

	First pass at removing use of TWeakObjectPtr from core replication classes. This should reduce FWeakObjectPtr::Get usage.

	Still expecting to see FWeakObjectPtr::operator= come up a lot. Going to tackle this in a second pass which will require some deeper refactors.

	#UE4 IsLoadedByEditorPropertiesOnly is not working properly so I removed it from FullLoadAndSave


Change 3681342 by Bob.Tellez

	#UE4 Added a FullLoadAndSave option to cooking, which simply loads all content then saves it to avoid the overhead of managing which packages need to be cooked. Large perf improvement for those who cook by the book and can fit the entire game in memory


Change 3681014 by Yenal.Kal

	#jira FORT-56209
	#jira FORT-56272

	Fixed a bug in the ability system where the ability ended callbacks could cause the ability end to be called again in the same call stack even though the ability is activated only once.

	This was happening because we were broadcasting the event before we decrement the active count.

Change 3680739 by Michael.Trepka

	Added some debugging code to help track down why shaders are hashing poorly.


Change 3671498 by Luke.Thatcher

	 [~] Modify new frame syncing to reduce performance regression seen when the game is running over budget.
	 - Rather than forcing a flip sync after we kick off one frame early, we just continue to kick frames if we time out. This allows the game thread to get ahead when we're over budget.
	 - The game thread will naturally resync with the vsync when we return to being in budget.

	#jira FORT-55842

Change 3671079 by Ryan.Gerleve

	Fix an edge case where the PackageMap on the server would try to resolve objects from default NetGUIDs even if their outer has already been garbage collected. This could lead to a completely unrelated object being returned instead of null, leading to asserts and potentially other issues.

	#jira FORT-55763


Change 3670487 by Zak.Middleton

	Optimize some low level details of UNetConnection::ClientHasInitializedLevelFor() and UNetDriver::IsLevelInitializedForActor(). Add cached WorldPackage for NetDriver to avoid repeated GetOuterMost() and Casts. Remove rendundant virtual GetWorld() calls, and mark UNetDriver's version "final" to let it optimize away virtual call. Made UNetConnection::ClientVisibleLevelNames a TSet instead of TArray, since it is searched frequently when there are streaming levels present.

	#jira FORT-55999

Change 3670351 by Zak.Middleton

	Back out changelist 3669817 (networking optimizations). Would rather have more testing before it goes to Release-Next. Will resub just for main and RP.

	Fixed server crashing after hotfixes have re-imported curve table data
	- The hotfix system is capable of replacing the content of a UCurveTable on the fly
	- If any systems had references to inner curves on that curve table, they would become invalid
	- This needs to be fixed in 1.6.4 (tonight) and also in 1.7

	#jira FORT-55792

Change 3665063 by Daniel.Broder

	Fixed crash in GameplayTagQueryCustomization when choosing "Save and Close" on GameplayTagQuery after setting a query due to nullptr NotifyHook in CloseWidgetWindow.

	Added additional if (StructPropertyHandle.IsValid()) wrappers and one check(StructPropertyHandle.IsValid()); the former to be consistent with other code and prevent possible crashes, the latter to at least catch the cause of a possible crash properly without having to change the code more significantly to handle it gracefully.

	Also changed some if( X ) to if (X) to match coding standards and provide consistency within the file.


	Michael, I'm Reviewing you on this fix since you brought this change over from Framework.  And Marc because you reviewed him on that change.

	Copy CLs 3383318 & 3388506 from //Orion/Main/Engine/Source/Runtime/Engine/...
	- Been testing with this for a while now
	- This change makes particle effects show up on the current frame's pose for skel meshes as well

	Removed my StopAllMontagesByGroupName temp hack

	CL 3383318
	Delay dispatching of AnimEvents (Notifies and Montage Events) until after we receive an updated animation pose (if applicable).
	This fixes AnimNotifies playing particle effects using a socket location using last frame's pose. Now they use the current frame's pose.

	CL 3388506

	Delay clearing of MontageInstances and triggering 'OnAllMontageInstancesEnded' until all Montage Events have been dispatched.
	Also fix SkelMeshComponent ticking on dedicated servers when rejoining in progress.

	#jira FORT-55102 - Server Crash UAnimInstance::StopAllMontagesByGroupName

Change 3780616 by Gil.Gribb

	Fixed and reenabled r.DelaySceneRenderCompletion

Change 3778979 by Gil.Gribb

	UE4 - Improved the performance of grass updates and added the ability to not do all of them every frame.

Change 3778200 by Nick.Darnell

	UMG - Making it possible to cancel delays and all animations on widgets.  Useful when destroying a widget and needing to stop any async state.

Change 3777612 by Zak.Middleton

	Perf: Added option to CharacterMovementComponent to skip immediate forward prediction for proxies on the frame they receive a network update (bNetworkSkipProxyPredictionOnNetUpdate). This avoids all forward prediction sweeps and floor checks on those updates. Intermediate frames will interpolate with prediction. This can also be disabled globally with the CVar "p.NetEnableSkipProxyPredictionOnNetUpdate 0".
	Added NetworkSmoothingDisableProxyPredictionForPawnLOD to force disabling full simulation for LOD >= this value (currently 3, so bottom 75 pawns). This takes precedence over current distance and view angle checks for prediction (mesh interpolation is untouched).

Change 3774338 by Ben.Woodhouse

	Convert the D3D12 PSO caches to use RwScopeLocks. This change is courtesy of a shelf from Gil, plus a couple of minor fixes.
	Saves up to a millsecond of frame time in CPU-bound scenarios

Change 3773462 by Gil.Gribb

	UE4 - Add particle batching. This is disabled by default but can improve thread scheduling when there are lots of very fast particle systems.

Change 3771375 by Hongyi.Yu

	Fixed the crash where ability components are unregistered and then re-registered, which usually happens in PIE.

Change 3771368 by Ben.Zeigler

	#jira UE-52670 Add project setting bValidateUnloadedSoftActorReferences that is true by default to match current behavior. If you set it to false it will no longer load packages to look for soft actor references when deleting/renaming actors.

Change 3771173 by Seth.Weedin

	Auto manage attachment support for AudioComponent- An opt-in feature that allows AudioComponents to cache their AttachParent/AttachSocket and only attach themselves when playing audio, detaching after playback is completed. Set to false by default.

Change 3768811 by Ori.Cohen

	Change animation scale collision code so that it uses the physics asset.

	Fix muting being unable to find remote player controller

Change 3768117 by Ori.Cohen

	Prevent pawn collision from updating during animation

Change 3766554 by Gil.Gribb

	UE4 - Added a new option to add and remove from static draw lists on demand. This is off by default.

Change 3766427 by Nick.Darnell

	Slate - Finally adding Opacity to SWidget.  Any widget can now be alpha animated at will, no more need to waste overhead by wrapping things with SBorder or making them userwidgets just to be able to animate a fade.

Change 3761682 by nick.darnell

	Athena - Introducing a way to interrupt the request to scroll and item into view.  In cases where you're animating, quickly showing and hiding, with the item widgets unavailable for a few frames, you enter cases where the deferred navigation is resolved after you've canceled showing a dialog stealing focus.

Change 3761416 by Ben.Zeigler

	#jira UE-52287 Prevent cook metadata like DevelopmentAssetRegistry.bin from being packed into a shipping game, by moving it into a Metadata subdirectory and updating deployment scripts to avoid that directory.
	Right now it doesn't package them at all, we could change it to package them as Debug Non-UFS if desired
	Change it so the asset audit UI will only load DevelopmentAssetRegistry.bin files, the cooked registry files don't have enough information any more to be useful
	Remove ability for runtime game to load DevelopmentAssetRegistry.bin, this ended up not being useful

Change 3750998 by Ethan.Geller

	#jira FORT-60191 Allow -audiomixer command line arg to work on all platforms.

	Set distance field self-shadow bias without recreating all render states

Change 3730756 by Ben.Woodhouse

	HISM optimization:
	Gil's change to skip trees with only one level of hierarchy (working around badly tuned content issues)
	Change vert threshold to 2K.
	1-2ms renderthread win without impacting GPU when rendering point lights

Change 3724029 by Zak.Middleton

	Increase allowed time for movement substep duration. Don't want to lower between 2 iterations, as this is not used much in practice other than deflection and movement mode changes, and that will change behavior (lose momentum). This new setting will absorb longer hitches in the common case (moving without collision or falling).

Change 3723985 by Marc.Audy

	SignificanceManager PostSignificanceUpdate functions can now be executed sequentially on the game thread as well as concurrently in the parallel for (old behavior)

Change 3722910 by Jian.Ru

	Amortize shadow cache update caused by resolution change
	Changed to use view distance vs. view space z when calculating whole scene shadow resolution which is less sensitive to camera rotation

Change 3718247 by Yenal.Kal

	Fixed the bug where the gameplay effect durations can show incorrect values after rejoin or after server time drifting away from the client.

Change 3716343 by Jamie.Dale

	Adding Korean and Turkish to the localization automation


Change 3710534 by Uriel.Doyon

	Texture streaming optimization where a maximum texture resolution for each level streaming data is computed per view.
	This is used to cull irrelevant levels and reduce the async task number of iterations.
	The culled size is defined by the new r.Streaming.MinLevelTextureScreenSize.

	This requires to remove primitives with big UV density from the level data.
	Those primitives get moved to the dynamic lists.
	This is controlled by r.Streaming.MaxTextureUVDensity

Change 3707207 by David.Ratti

	Remove look ahead-vectors prediction in FNetViewer. This (requires) a line trace which is not desirable or really accurate anymore. This saves us a line trace per connection per multicast rpc.

	unify reliable multicast rpc handling: these now do relevancy checks and are not sent to non relevant clients

Change 3706272 by Thomas.Sarkanen

	Added utility/math functions to aid in optimizing anim blueprints

	Added VectorLengthXY to get the 2D length of a 3D vector. Avoids unecessary conversions.
	Added polar->cartesian->polar conversion helper functions for expensive frequently-used anim graph functionality.

Change 3706159 by David.Ratti

	PlayerState/ASC replication optimizations from Polge: this puts the net update frequnecy on player state back to 1hz while forcing netupdates on the player state actor when the ability system component needs to update

Change 3692891 by David.Ratti

	Optimizations for UNetConnection::ClientHasInitializedLevelFor: build acceleration map of actor outer's (ULevels) -> Visibility bool. Existing logic stays the same.

Change 3691392 by Aaron.McLeran

	#jira UE-50628 Fix audio trying to sync load bulk data with EDL enabled

	- Fix log error in BulkData.cpp
	- Make the first stream chunk be force inline payload in bulk data flags so it loads immediately vs in async IO system
	- Make audio stream chunks get as close to 256 k chunks as it can, zero-pad rest to be 256 k aligned
	- Fix up DDC key, serialize AudioDataSize separately from chunk DataSize

Change 3682683 by Zak.Middleton

	Add bOnlyTickMontageOnDedicatedServer variable to AnimInstance, to avoid anim bp updates on dedicated server. Turn on to fix hitching from queued ServerMove() calls, and some free perf during all montages on the server.

Change 3678771 by Ori.Cohen

	Added the ability to turn on stack walk during hitching vs lightweight stats

Change 3676363 by Ori.Cohen

	Added the ability to get callstacks as part of hitch detection

Change 3674877 by Keith.Judge

	Move definition of GFailedToFindParamCollectionBufferQueue to ShaderBaseClasses.cpp so that all targets can successfully compile.

Change 3672515 by Bob.Tellez

	Added code to play wind particle effects

Change 3670909 by Zak.Middleton

	Fixed ForcePositionUpdate() not calling CheckJumpInput(). Added "p.NetForceClientServerMoveLossPercent" cvar to simulate loss of client->server movement RPCs (without hosing the rest of networking).
