	Linux: switch to Vulkan by default (UE-62807).

	- Default behavior: attempt Vulkan first, but in case of failure instead of quitting silently fall back to GL, unless -vulkan is passed.
	- Forcing GL is still possible.

	Fix standalone applications after the Vulkan switch.

Change 4277968 by Arciel.Rekman

	Linux: make CrashReportClient headful (UE-14089).

Change 4285622 by Arciel.Rekman

	Merged from 4.20.2: Linux: do not refuse to start if system limits cannot be raised (UE-62515).

	- Too aggressive behavior, which can break cooking for no valid reason.
	- If a commandline argument is used, the engine will still treat inability to raise the limits as an error.

	(Edigrating 4273547 from //UE4/Release-4.20/... to //UE4/Dev-Console/...)

Change 4293083 by Arciel.Rekman

Change 4305659 by Marcin.Undak

	[Vulkan][Engine] Update the Vulkan RHI to obey r.VSync (and the vsync and novsync command-line arguments).

	Change 4222769 by Jason.Stewart@Jason.Stewart_AMD_Dev_Rendering_threadripper-win10 on 2018/07/19 10:55:48

		The original implementation ran into a latent thread hazard between the RHI thread and the rendering thread, where the rendering thread would try to use the backbuffer of the swap chain while the swap chain was being recreated (specifically after the swap chain recreation code had released and nulled out the back buffer, but before swap chain creation had actually happened to get a new back buffer). This implementation addresses that issue.

		This is Tim's code. I'm just submitting it as Tim is currently out of office.

Change 4305661 by Marcin.Undak

	Moved libwebm and libvpx inside WebMMediaPlayer directory

Change 4308659 by Marcin.Undak

	https://ec-01.epicgames.net/commander/link/jobDetails/jobs/8641984?

Change 4321942 by Brandon.Schaefer

	Github PR #4167 (thanks maiself!)

	#jira UE-51681

Change 4328963 by Arciel.Rekman

	TestPAL: improve the test by randomizing allocation size.

	- The range will no longer be constrained to <=128KB at once, allocations can be as big as 16MB but they will unevenly distributed, with smaller sizes being more frequent.

Change 4329208 by Arciel.Rekman

	hlslcc: suppressed benign compiler warning during the Linux build (UE-43988).

Change 4329283 by Arciel.Rekman

	Linux: replace CachedOSPageAllocator with PooledVirtualMemoryAllocator for Linux.

	For the explanation of FPooledVirtualMemoryAllocator, see PooledVirtualMemoryAllocator.h
	For the details, test data and comparisons, message Arciel Rekman.

	Relevant command line args added:

	-vmapoolscale=<float> (defaults to 1.4)
	-vmapoolevict
	-novmapoolevict

	By default, freed memory will not be evicted from RAM (unless running on a server)

	Also changed:
	- Removed the fixed-size pool previously used by Linux (and supporting machinery like scaling it on start)
	- Replaced the way we manage free blocks from pointers to a bitmap to reduce memory footprint.

Change 4331946 by Luke.Thatcher

	[CONSOLE] [^] (merging CL 4162064) Implement new thread heart beat clock to solve the suspend/resume problem across all platforms.
	 - The hang and hitch detectors now maintain their own clocks which are ticked by their respective threads.
	 - If the title is suspended, the ticking thread will stop and the clock will stop advancing. On resume, the maximum delta in the clock is clamped to a small value, so we ignore all the time the thread was not ticking for (i.e. the duration of the title being suspended).
	 - As such, we don't need any logic for handling PLM suspend/resume in the hang and hitch detectors, so this change removes that too.

	#jira FORT-96886

Change 4331973 by Luke.Thatcher

	[CONSOLE] [^] (merging CL 4183499) Add frame-present-based hang detection.
	 - RHIs call FThreadHeartBeat::PresentFrame() whenever they present a frame to the swap chain.
	 - These calls form a separate heartbeat from the thread-based ones, allowing the hang detector to fire if, for example, the game thread is stuck in an async loading loop and is ticking the game thread heartbeat, but making no progress.
	 - Also refactored ThreadHeartBeat.cpp to move hang detection logging into a FORCENOINLINE function. This will put OnHang and OnPresentHang at the top of the callstack in retail crash dumps, making the bucketing easier to recognise.

Change 4332200 by Luke.Thatcher

	[CONSOLE] [+] (merging CL 4227517) Add PlatformDebugData to FShaderResource.
	 - We can use this to store platform specific shader symbols etc. The data gets serialized to the DDC and can be retrieved during a cook.
	 - Data is entirely discarded in cooked builds, and is a no-op on platforms which don't implement support for shader debug data.
	 - Bumped shader version to invalidate DDC keys.

Change 4332407 by Luke.Thatcher

	[CONSOLE] [CORE] [!] (merging CL 4279686) Fixed unaligned integer load macro inconsistencies.
	 - Renamed PLATFORM_SUPPORTS_UNALIGNED_INT_LOADS to PLATFORM_SUPPORTS_UNALIGNED_LOADS
	 - Merged it with REQUIRES_ALIGNED_ACCESS and REQUIRES_ALIGNED_INT_ACCESS
	 - Fixed Linux platform which had both the old macros defined to 1, which is wrong because they are mutually exclusive.

Change 4333386 by Luke.Thatcher

	[CONSOLE] [!] (merging CL 4317367) Fix compile error in AnimationCompression.h

Change 4334395 by Arciel.Rekman

	Corrected PLATFORM_DESKTOP definition.

Change 4336190 by Anthony.Bills

	(Original CL4314280) Use the debug file writer when using framepro. This buffers more data which should reduce stalls when writing out on certain platforms.

	#jira none

Change 4336291 by Anthony.Bills

	Use a clamped local clock when timing out the renderthread.

	- This prevents suspend and resume issues on platforms where suspend events may not occur or the system clock is not set to the process time.

	#jira none

Change 4336292 by Anthony.Bills

	(Orignal CL 4195778) Fix printing of the hang detector multiplier and other logging.

	"f" is the correct format specifier for a double.

	#jira none

Change 4336307 by Anthony.Bills

	(Orignal CL 4257875) Use the correct clock when printing the scoped hitch stat.

	- Needs to be the internal FGameThreadHitchHeartBeat clock incase FPlatformTime::Seconds becomes out of sync with FrameStartTime.

	#jira none

Change 4336321 by Anthony.Bills

	(Original CL 4258186) Add GetNoInit function to FGameThreadHitchHeartBeat.

Change 4339239 by Ben.Woodhouse

	Integrate-as-edit CL 4292520

	Support different sized buffers for FArchiveFileWriterGeneric per-platform so we can tune per-platform as needed.
	No changes to existing defaults values of 1KB for read, 4KB for write:

	        #define PLATFORM_FILE_READER_BUFFER_SIZE 1024
	        #define PLATFORM_FILE_WRITER_BUFFER_SIZE 4096

	#jira UE-63394

Change 4339623 by Anthony.Bills

	[Linux] Update native toolchain buildscript to support clang 6.0.1

	- Main issue was due to libxml2 as an extra dependency of some test libraries, so needs to be disabled via DLLVM_ENABLE_LIBXML2.

Change 4341804 by Luke.Thatcher

	[CONSOLE] [!] Fix memory scribble in black depth texture cube on platforms with 16-bit depth.
	 - Original code was writing a FColor into the locked texture data, which causes a 2 byte scribble if the PF_ShadowDepth format is 16-bits.

	[!] Also fixed GWhiteTextureCube being black. FColor::White is not a compile-time constant, so an initialization order problem meant the value of FColor::White is actually black when the GWhiteTextureCube constructor runs.

	#jira none

Change 4342244 by Anthony.Bills

	[Linux] Allow restarting the crashed application from the crash report client

	#jira UE-62903

Change 4342636 by Brandon.Schaefer

	Fixed assert in console

	#jira UE-63643


Change 4345166 by Luke.Thatcher

	[CONSOLE] [!] (merging CL 4345072) Fix initialization order bug with FColor and FLinearColor constants.
	 - The original constants were dynamically initialized during startup. Using these constants from other global constructors may result in getting the wrong value (transparent black) if a given constructor runs before FColor/FLinearColor's constructor.
	 - Adding constexpr to the FColor/FLinearColor constructor makes these constants known at compile-time, and included in the readonly data section, so they don't require dynamic initialization.

	[~] Also restores the original constant color values in RenderUtils.cpp

	#jira none

Change 4345860 by Arciel.Rekman

	Make StompMalloc return 16-byte aligned memory on 64 bit platforms (UE-63743).

3551dbb56a # Cooker Optimizations
Change 4295817 on 2018/08/17 by Stefan.Boberg@swarm-74ee0b66-39c6-77ae-e314-cb70d93cd03e

        Added tracking of UPackage instances to UCookOnTheFlyServer to reduce UnsolicitedPackages overhead

        Optimized UCookOnTheFlyServer::GetAllUnsolicitedPackages - no longer iterates over global UObjects array to find freshly loaded UPackages containing maps

        Also optimized UCookOnTheFlyServer::GetUnsolicitedPackages but there's more work to do here to reduce repeated processing for the same packages

        This change reduces the overall time spent cooking Fortnite by some 30% - will mostly benefit projects with large number of assets.

Change 4317978 on 2018/08/27 by Stefan.Boberg@sbo1

        Major optimization: eliminate GetUnsolicitedAssets from main cooker loop

        This reduces the overall time spent in the cooker by an additional 30% in the Fortnite case. Change will benefit any game with large (>100k) asset counts as the previous logic was basically exponential complexity.

        Also eliminated presave logic (to simplify maintenance)

Change 4317976 on 2018/08/27 by Stefan.Boberg@sbo1

        Changed package probing logic so it probes for binary formats first, text second

        This improves performance for the current common case by reducing needless syscalls

Change 4291839 on 2018/08/16 by Stefan.Boberg@swarm-74ee0b66-39c6-77ae-e314-cb70d93cd03e

        Fix for external profilers. The loop iterating over the available external profilers did actually not iterate over the available external profilers.

Change 4318144 on 2018/08/27 by Stefan.Boberg@sbo1

        Fixed out of bounds read in FWindowsPlatformMisc::QueryRegKey.

        String buffer size in bytes was erroneously used instead of length in characters to construct result FString.

        Edigrated CL4318138 by Yuriy O'Donnell

Change 4318920 on 2018/08/27 by Martin.Ridgers@martin-dev-core-hq

        The FPackageTracker can get informed about objects of a blueprint-derived type where the type object has already been garbage collected. This makes it unsafe to use the UClass pointer. Instead we just check the UClass pointer to see if it matches the

Change 4316152 on 2018/08/24 by Chad.Garyet@cgaryet_dev_core

        updating fortnite packaged build to match main

Change 4303490 on 2018/08/21 by Stefan.Boberg@sbo1

        Fixed include file casing for "Cooker/PackageNameCache.h"

Change 4303326 on 2018/08/21 by Stefan.Boberg@sbo1

        Extracted package name cache related code into separate header

        Small part of refactoring UCookOnTheFlyServer monolith into more manageable components to aid optimization and maintenance

Change 4303251 on 2018/08/21 by Stefan.Boberg@swarm-74ee0b66-39c6-77ae-e314-cb70d93cd03e

        Removing checked-in SDF files bloating the tree

        These SDF files contain Intellisense data and can be rather large (some of these were 50-100MB). They will be regenerated by VS on solution open so no need to check in.

Change 4300713 on 2018/08/20 by Stefan.Boberg@sbo1

        Moving more state out of the public header for CookOnTheFlyServer

        No functional change -- just restructuring code in preparation for refactoring+optimization.

Change 4300510 on 2018/08/20 by Stefan.Boberg@sbo1

        Added some filtering logic to ensure the new package tracking logic matches the old iteration code.

        Exposed by CI on EngineTest, which evidently has more elaborate data setups than InfiltratorDemo

Change 4300489 on 2018/08/20 by Stefan.Boberg@sbo1

        Added check in order to suppress CIS static analysis warning

Change 4299938 on 2018/08/20 by Stefan.Boberg@sbo1

        Refactoring: moved some CookOnTheFlyServer definitions from header to cpp (no behaviour change)

        Makes it easier to change implementation and reduces iteration time - when the header is touched then we end up running UHT

        - FFilePlatformCookedPackage

Change 4299866 on 2018/08/20 by Stefan.Boberg@sbo1

        Removed LeakTest functionality - not useful, also likely not functional since the code path has not been exercised for a long time

Change 4287838 on 2018/08/15 by Stefan.Boberg@sbo1

        - Eliminating ShouldCook function which only returns true -- resulted in pointless temporary string allocations. Also, needless clutter.
        - Eliminated redundant GetCachedStandardPackageFileFName call
        - Fixed exception slicing rethrow in SaveCookedPack

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

Change 3836829 by Ben.Marsh

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

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 4042043 by Steve.Robb

	GitHub #4705 : Added weak lambda's for delegates and multicast delegates.

Change 4042056 by Robert.Manuszewski

	Optimized Mark Phase of GC by up to 10ms by making it run in parallel and removing a huge array presize which we didn't need.

Change 4042104 by Robert.Manuszewski

	Set the minimum GC cluster size to 5 so that GC doesn't have to process micro clusters which are more expensive than processing individual objects

	+ Exposed the minimum cluster size to ini and project settings as gc.MinGCClusterSize
	+ Added the ability to sort clusters by name/object count/mutable object count/referenced clusters count when dumping them with gc.ListClusters command

Change 4042377 by Robert.Manuszewski

	Reworked how GC and other threads (ALT specifically) interact - GC will now notify the ALT it wants to run and ALT will immediately try to finish its current work to allow that. Also the entire ALT tick is now protected against GC running at the same time to improve ALT stability.

	+ added gc.ForceCollectGarbageEveryFrame console variable that triggers a forced GC every frame

Change 4042427 by Robert.Manuszewski

	Changed FGCCSyncObject to use events when waiting for GC to finish so that it doesn't spin on non-game threads when GC is running

Change 4042482 by Robert.Manuszewski

	Unhashing unreachable objects (ConditionalBeginDestroy) will now also be done incrementally, just like the purge phase of Garbage Collection

Change 4042635 by Robert.Manuszewski

	Fix for a potential assert when incremental purge garbage is pending and something forces a full purge

Change 4044092 by Steve.Robb

	Fix for forward declared CoreUObject weakobject types in delegates when building in Clang.

Change 4044102 by Robert.Manuszewski

	Fix for a possible hang when worker threads are preventing GC from running and something is later trying to FlushAsyncLoading with the Async Loading Thread enabled

Change 4044113 by Steve.Robb

	Another Clang fix.

Change 4044160 by Robert.Manuszewski

	Disregard For GC pool will now be enabled by default in cooked builds

Change 4044287 by Steve.Robb

	Typo fix.

Change 4047723 by Graeme.Thornton

	TBA: Fixes for import/export name cache and object resolving

Change 4048015 by Graeme.Thornton

	TBA: Weak/Soft/Lazy pointer serialization changes

	* Remove FWeakObjectPtr::Serialize, move it's logic into, and replace usages of with calls to, FArchiveUObject::SerializeWeakObjectPtr(). Ensures that something is always sent to the archive so that structured archives can be kept happy in the future.
	* Added Weak/Soft/Lazy pointer handling to the structured archive slot interface and all the formatters. Binary formatters just forward the call onto their inner and text archives store as a string path reference.
	* FArchiveUObjectFromStructuredArchive caches all these pointer types and stores indices in the binary block, same as with a UObject*. All pointers are then forwarded to the underlying formatter in one go on finalization.

Change 4048021 by Steve.Robb

	Fix for binding an unbound TFunction to another TFunction with a different signature.  Also all null pointers now count as unbindings, not just nullptr.
	TIsMemberPointer added.
	TIsATFunction and TIsATFunctionRef renamed to remove the 'A's.

Change 4048544 by Robert.Manuszewski

	Fixing ConditionalBeginDestroy profiling after changes to incremental CBD.

Change 4051028 by Graeme.Thornton

	TBA: ArchiveFromStructuredArchive adapter uses Inner to determine if it is outputting to text, and sets it's own ArIsTextFormat to false

Change 4051056 by Graeme.Thornton

	TBA: High level tagged property / UObject base class text serialization
	 - UObject serialize converted to structured archive
	 - Properties written to text individually with text tags, and then binary adapted values
	 - Only saves, doesn't load

Change 4051111 by Graeme.Thornton

	TBA: Temporarily disable loading of text assets until tagged property serialization path is fixed up

Change 4051154 by Graeme.Thornton

	TBA: Convert a few uobject serializers to structured archive format for example purposes

Change 4051181 by Graeme.Thornton

	TBA: Added default structured archive implementation of SerializeItem to UProperty, which just calls the FArchive version on an FArchiveUObjectFromStructuredArchive adapter. Implemented structured archive SerializeItem for UArrayProperty

Change 4051197 by Graeme.Thornton

	TBA: ObjectProperty text serialization

Change 4051216 by Graeme.Thornton

	Restored a modified FWeakObjectPtr::Serialize function to keep backwards compatibility in code I don't have access to.

Change 4051261 by Graeme.Thornton

	TBA: Convert UMetaData to structured archive

Change 4051374 by Steve.Robb

	Incorrect assert removed.

Change 4051562 by Robert.Manuszewski

	Adding stats for the new GC internal functions

Change 4051614 by Graeme.Thornton

	TBA: Removed UProperty::SerializeItem(FArchive, ...) and replaced with UProperty::SerializeItem(FStructuredArchive::FSlot, ...). Fixed up most of them to work properly and added adapters in for any that were non-trivial.

Change 4052512 by Graeme.Thornton

	TBA: Temporary workaround for softobjectptr and lazyobjectptr uproperties not serialization anything when they know the archive is a reference collector. They should always be serializing their pointers and letting the underlying archive itself ignore them.

Change 4053917 by Robert.Manuszewski

	Clustered objects from clusters that are no longer reachable will now be marked as unreachable immediately when gathering unreachable objects

Change 4053919 by Robert.Manuszewski

	Added the ability to disable incremental BeginDestroy in ini/project settings

Change 4055518 by Daniel.Lamb

	Fixup for deterministic audio generation issue.
	Submitted on behalf of Rich.Whitehouse

	#jira nojira
	#test prefilght automated test.

Change 4056854 by Graeme.Thornton

	TBA: Added a test asset to EngineTest which contains all the different property types and test cases.

Change 4056858 by Graeme.Thornton

	TBA: Updated USetProperty to proper structured archive usage

Change 4056872 by Graeme.Thornton

	TBA: Add map property field to test object

Change 4056873 by Graeme.Thornton

	TBA: Convert UMapProperty to full structured archive

Change 4056994 by Graeme.Thornton

	TBA: Converted FText over to structured archive. Implemented saving, but not loading.

Change 4059728 by Ben.Marsh

	UBT: Add support for using adaptive non-unity builds when the engine and project are in separate repositories.

Change 4059805 by Graeme.Thornton

	Fixed typo in text serialization. Fixes CIS automation test errors

Change 4060007 by Graeme.Thornton

	TBA: FArchiveFromStructuredArchive will now access it's host slot lazily, i.e. only when a value is actually written to the archive.

Change 4060092 by Stefan.Boberg

	Added optimized Windows console window output path to GenericConsoleOutput since this slowed down cooking considerably (2 minutes spent in wprintf alone for one large dataset)

	When stdout is attached to a console we use the WriteConsoleW function instead of wprintf since the latter is very slow especially in unbuffered mode which the engine currently configures for stdout (see setvbuf call in LaunchEngineLoop.cpp).

	At some point we should reconsider this buffering policy since it's likely to slow down other platforms as well but I wanted to do a safe change for now as I don't yet fully understand why the setvbuf call is there in the first place.

Change 4060108 by Stefan.Boberg

	Introduced some additional target platform utilities to help with asset cook optimizations

	* We now assign each ITargetPlatform a zero-based ordinal value
	* Introduced FTargetPlatform and FTargetPlatformSet types to help store platform references and platform sets efficiently.

	These are not currently used in the engine but are designed to replace the existing ITargetPlatform/string/FName representations in the cooking data structures.

Change 4060143 by Graeme.Thornton

	Undo //UE4/Dev-Core/Engine/Source/Runtime/... changelist 4060007

	Needs some other changes that I haven't checked in yet...

Change 4062432 by Ben.Marsh

	Fix error message when enumerating P4 changes.

Change 4062648 by Ben.Marsh

	Add missing p4 integration action.

Change 4063620 by Graeme.Thornton

	Integrated a fix from UDN where the engine would crash when trying to load a very small encrypted file (<16bytes) from a pak file, where the read address wasn't already aligned to the AES block size.

	(https://udn.unrealengine.com/questions/431989/crash-while-reading-a-very-small-file-in-encrypted.html)

Change 4066963 by Robert.Manuszewski

	Fixing GC cluster verification code reporting false positives when a cluster is referencing another cluster through 'mutable' objects list.

Change 4067133 by Robert.Manuszewski

	Changed log verbosity when reporting individual cases of GC cluster assumption violations as they are followed by an asser anyway and this way we get the chance to see all issues before we assert at the end of these checks.

Change 4067443 by Steve.Robb

	FString can now be constructed from any char pointer type and length.

Change 4068156 by Steve.Robb

	Fix necessary because of FString constructor change in CL# 4067443.

Change 4070258 by Graeme.Thornton

	Fixes for VSCode

Change 4070372 by Graeme.Thornton

	TBA: Script struct serialization to structured archives

Change 4071913 by Ben.Marsh

	Move bulk of the code for UnrealPak into an engine developer module, so it can be used in the editor.

Change 4071914 by Ben.Marsh

	Missing files.

Change 4071937 by Ben.Marsh

	Missing header.

Change 4072015 by Ben.Marsh

	Fixes for compiling PakFileUtilities as part of the editor.

Change 4072826 by Steve.Robb

	TBitArray::Reserve() added.
	TBitArray::Add() overloaded to allow adding multiple bits.
	TSparseArray::Reserve() optimized to call the overloaded Add().

Change 4073271 by Daniel.Lamb

	Fixed add patch tier in project launcher passing the wrong commandline option to UAT.

	#test none

Change 4074708 by James.Hopkin

	#core Removed redundant Casts

Change 4074763 by Steve.Robb

	Fix for TSparseArray::Reserve() size.

Change 4076063 by Ben.Marsh

	Add an "UnrealPak" commandlet with the same functionality as the standalone UnrealPak program. Invoke by running the editor with -run=UnrealPak and the standard UnrealPak commandline options.

Change 4077064 by Robert.Manuszewski

	Fixing compile error in PakFileUtilities

Change 4077144 by Graeme.Thornton

	TBA: TextAssetCommandlet improvements

	* Collect lists of broken assets during roundtrip tests and print a summary of packages that failed each phase at the end
	* After resaving as text, load the file back as a plain JSON hierarchy to ensure the output was valid

Change 4077412 by Ben.Marsh

	Set the correct exit code for UnrealPak. Should return 0 on success, not 1.

Change 4077760 by Graeme.Thornton

	TBA: Loading fixed for tagged property serialization

	Includes conversion of all UProperty::ConvertFromType() and SerializeFromMismatchedTag() functions to use structured archives

	Lazy initialization of FArchiveFromStructruredArchive when loading, to support the possibility of an adapter being create around an object property serialize call to its inner UStruct, which then decides not to do anything and return false. Stops the ArchiveFromStructuredArchive from consuming the slot and getting upset later on when we try to serialize normal tagged properties from it.

	Disabled lazy bulk data loading from text assets. Requires a bigger change to make it work.

	Added some debug checks to json input formatter which track the current value stack size when a new object is pushed onto the stack, and makes sure that the stack has returned to the same size when the object is popped. Catches cases where we unpack an array/stream to the value stack but then don't consume all the items.

Change 4078800 by Ben.Marsh

	Change UAT to using the editor's UnrealPak commandlet rather than invoking the standalone UnrealPak executable. To improve performance when building several PAK files, also add a new -batch=<file> command which reads commands to execute in parallel from a text file.

Change 4079745 by Graeme.Thornton

	TBA: Migrated a couple of UObject Serialize functions to FStructuredArchive (SoundCue / MaterialExpressions / Editor strip flags)

Change 4079847 by Graeme.Thornton

	TBA: Add 'FindMismatchedSerializers' mode to text asset commandlet, which dumps out a list of all UClasses which don't have the CLASS_MatchedSerializers flag, meaning we can't guarantee the have Serialize functions for FArchive AND FStructuredArchive, therefore we can't use the new structured archive based serialize path. Should only ever be native instrinsic classes as UHT takes care of all other cases.

Change 4079925 by Ben.Marsh

	Fix incorrect assignment when deriving name for chunked pak file.

Change 4080214 by Ben.Marsh

	Move the ThreadPoolWorkQueue class into DotNETUtilities so it can be used by other projects.

Change 4082394 by Graeme.Thornton

	CIS fix for variable shadowing warning

Change 4082583 by Ben.Marsh

	Add a IBinarySerializable interface for types that support reading from a BinaryReader and writing to a BinaryWriter. Implementing IBinarySerializable implies a constructor taking a BinaryReader argument is available for deserializing.

Change 4082652 by Ben.Marsh

	Fix FileReference.Directory not returning a directory with a trailing backslash for files in the root directory.

Change 4082755 by Graeme.Thornton

	Fixed an erroneous usage of TUniquePtr<uint8>as a pointer to a uint8 array when creating pak files. Caused a crash when compression was enabled, and has probably surfaced because pak generation is now done by an editor commandlet rather than a standalone program.

Change 4082756 by Graeme.Thornton

	Fixed some incorrect documentation for pakfile compressed chunk headers

Change 4082883 by Graeme.Thornton

	Static analysis warning fix

Change 4082912 by Ben.Marsh

	Move ExceptionUtils into DotNETUtilities.

Change 4085291 by Graeme.Thornton

	TBA: In the Json output formatter, write float and double values out with enough precision for successful roundtripping. Added some debug only code which will immediately reconvert the string back to its original value and compare the the input

Change 4085523 by Graeme.Thornton

	TBA: Remove only explicit usage of DECLARE_FSTRUCTUREDARCHIVE_SERIALIZER. Should only be used from UHT generated code.

Change 4086037 by Robert.Manuszewski

	Fix for a potential race condition when two threads want to acquire GC lock

Change 4088655 by Graeme.Thornton

	Pak creation now uses the bEnablePakSigning setting from the crypto config json file

Change 4091474 by Steve.Robb

	Fix for TStaticBitArray::FindFirstSetBit() and TStaticBitArray::FindFirstClearBit().
	Unused variables removed.

Change 4093632 by Steve.Robb

	CIS fixes.

Change 4093656 by Graeme.Thornton

	Build fix

Change 4093744 by Ben.Marsh

	Allow per-chunk settings for whether to enable compression in UnrealPak.

Change 4099712 by Gil.Gribb

	UE4 - Fixed rare case where insufficient space was preallocated for cooldown ticks.

	#jira UE-59686

Change 4099912 by Stefan.Boberg

	Cooking timer optimizations:

	- Replaced data structures for FScopeTimer and FHierarchicalTimerInfo. Previous implementation used FString for many things and caused *lots* of heap and string concatenation activity. Replaced with a compile-time node id (using __COUNTER__) and raw string literals.
	- Removed PERPACKAGE_TIMER support (was disabled by default and was difficult to test)
	- Made it possible to toggle OUTPUT_TIMING and ENABLE_COOK_STATS independently
	- Removed some extremely tight timers because the overhead from calling QPC significantly exceeded the measured code

	This change shaved some 15% off a clean cook of Fortnite WindowsClient (en) with fully populated local DDC

Change 4100519 by Stefan.Boberg

	Quick fix for Linux build issue introduced in 4099927

Change 4105327 by Stefan.Boberg

	Cooker: Changed FHierarchicalTimerInfo so it uses a linked list for tracking child nodes, to be able to deal with any child count. Previously we assumed there would never be more than 9 children but it turns out there are cooker modes that need more.

	Fixes check when using -FullLoadAndSave to cook

Change 4105448 by Stefan.Boberg

	- Fixed Linux build warning re: member initialization order
	- Also eliminated OUTPUT_HIERARCHYTIMERS/CLEAR_HIEARCHYTIMERS macros (plain functions are fine)
	- Moved finishing-up code for FullLoadAndSave() to TickCookOnTheSide() call site to improve timer output. Previously some of the scopes would not have been closed before printing and thus the output was misleading.

Change 4109031 by Ben.Marsh

	Attribute-driven Perforce wrapper (old Epic Friday project). Offers a more complete implementation than the current P4 wrapper in UAT without requiring any platform-specific libraries. Uses the Python binary output for parsing.

Change 4109588 by Ben.Marsh

	UBT: Add extension methods for serializing a nullable type to a BinaryReader/BinaryWriter.

Change 4109595 by Ben.Marsh

	Missing project file for DotNETUtilities.

Change 4110724 by Stefan.Boberg

	Removed annotation map locking in UObjectMarks, eliminating around one minute (~3.5%) from Fortnite cook time.

	The locking was redundant since the annotation maps are managed per thread anyway.

Change 4111304 by Ben.Marsh

	UAT: Add support for setting a status message through the log class. Allows writing transient messages (eg. progress messages) which will be cleared out before writing other messages. Best used through the LogStatusScope class, which can set a status message for the duration of a using() block.

	As part of this change, the console no longer has to be added as a dedicated trace listener. Since we already special-case this listener when formatting log output, it's easier to just keep the implementation separate to the other trace listeners.

Change 4112708 by Steve.Robb

	Fix for TBitArray::MaxBits in assignment.

Change 4114133 by Stefan.Boberg

	Tweaked how low-level memory (LLM) tracker is implemented to reduce overheads.

	Previously FMemory functions would acquire the LLM singleton and call OnLowLevelFree/OnLowLevelAlloc etc which would check the bIsDisabled flag and early out if it was set. Due to how frequently these functions were called this ended up costing quite a bit.

	- This change makes the flag a static member variable instead of a member variable and therefore enables a simpler early-out to be implemented.
	- The singleton getter is also simplified to avoid hitting the threadsafe singleton construction path on every call.
	- The enable flag is no longer TAtomic - this also incurs extra overhead for no clear benefit

	Shaves approximately 3.5% (one minute) off a Fortnite cook test scenario (using -FullLoadAndSave)

Change 4115010 by Robert.Manuszewski

	Fixing CIS

Change 4115249 by Robert.Manuszewski

	Fixing async loading code asserts when exiting game very early due to an error

	#jira UE-56267

Change 4117091 by Ben.Marsh

	Prevent doubled-up lines when writing status updates with console log verbosity.

Change 4117207 by Ben.Marsh

	UGS: Do not include executables in diagnostics zip file, and ignore "no such files" error when cleaning workspace.

Change 4119175 by Ben.Marsh

	UGS: Fix crash writing version files when directory does not already exist.

Change 4119987 by Ben.Marsh

	UGS: Show a dialog box while the launcher is updating executables from Perforce, which allows cancelling the operation if necessary. Allow setting the username on the settings window, and prompt for login credentials if necessary. Should prevent situations where users have to update settings from the command prompt.

	Holding down shift during launch now shows the settings dialog rather than an immediate prompt to launch the unstable version (unstable version is shown as a checkbox on this dialog).

Change 4119991 by Ben.Marsh

	Update version number for UGS launcher to 1.13.

Change 4121943 by Robert.Manuszewski

	Don't use FArchiveAsync2 for reading packages with non-async path in editor builds as its performance is worse than the standard archive's (saves about 1 minute when doing larger cooks and 7 seconds when loading into PIE)

Change 4122592 by Steve.Robb

	GitHub #4762 : Improve wording and grammar of Math comments
	Also includes improved accuracy in FMath::ComputeBoundingSphereForCone().

Change 4122819 by Stefan.Boberg

	Don't call CreateDirectory redundantly when opening files for writing using FFileManagerGeneric::CreateFileWriter

	This change avoids calling IPlatformFile::CreateDirectoryTree if possible since this is a very expensive function especially for deep hierarchies as it performs directory creation from the root directory onwards instead of from the leaf downwards. That function should also be fixed but this change improves performance in the meantime.

Change 4122872 by Stefan.Boberg

	CreateDirectoryTree now creates directories leaf-to-root instead of the other way around. This is much more efficient since we don't spend time on system API calls for directories which already exist. This accounted for a very large amount of CPU time in cooking as the full target file directory hierarchy would be "created" for every single output file.

Change 4123109 by Stefan.Boberg

	- Disable overlapped I/O in editor / cooker. Synchronous I/O reduces the number of syscalls and Windows performs prefetching on our behalf anyway for sequential reads
	- Eliminated syscall which was issued for every write to update cached file size -- since we're the only writers to the file (file access allows read sharing at most) we can authoritatively update the file size on write completion

Change 4123455 by Ben.Marsh

	PR #4775: New build param PCHMemoryAllocationFactor to set /Zm VS build param. (Contributed by lucaswall)


Change 4124207 by Ben.Marsh

	UBT: Remove some unnecessary indirection for generated code paths.

Change 4124217 by Ben.Marsh

	UBT: Remove another unused variable from UEBuildModuleCPP.

Change 4124377 by Stefan.Boberg

	In IPlatformFile::DeleteDirectoryRecursively, attempt to delete file first and if it fails clear the readonly flag and try again

	Previously there was a call to clear the readonly flag for every deleted file and this is a waste of resources 99% of the time. The SetFileAttributes call accounted for a significant amount of time during cooker sandbox directory deletion

Change 4125071 by Stefan.Boberg

	Some tweaks to FQueuedThreadPoolBase scheduling and memory management

	- Explicitly pass in false for TArray::RemoveAt(..., bool bAllowShrinking) argument to prevent memory reallocation when arrays are drained and inevitably repopulated shortly afterwards
	- Use a MRU strategy instead of LRU when picking a thread to wake up. The MRU thread is the most likely to have a 'hot' cache for the stack etc. Picking from the back of the array also happens to be cheaper since
	no memory movement is necessary when RemoveAt is called. (This was the strategy in place before CL2600362 which seems to have changed it unintentionally)
	- Release lock as soon as a thread has been chosen, before asking the worker thread to wake up and do the work

Change 4126132 by Ben.Marsh

	UAT: Detect when stdout is redirected and prevent using backspace characters to move the cursor.

Change 4126867 by Graeme.Thornton

	TBA: Fix tagged binary formatter

Change 4127010 by Robert.Manuszewski

	AnimScriptInstances created at runtime will now also be added to the owning omponent's cluster to avoid GC issues.

Change 4127932 by Ben.Marsh

Change 4133681 by Ben.Marsh

	UGS: A per-project list of folders and extensions to be deleted by default when running the 'clean workspace' tool can now be specified through the <ProjectDir>/Build/UnrealGameSync.ini file. Settings may be specified for an individual branch (via a category with the depot path to the project) or for wherever the project is currently open (via the [Default] category).

	The SafeToDeleteFolders list specifies a substring that will be checked against folder paths. Anything containing this folder will be marked as safe for delete by default.

	The SafeToDeleteExtensions list specifies a list of extensions for files that can always be deleted.

	Example:

	 [Default]
	+SafeToDeleteFolders=/MyGame/Test/
	+SafeToDeleteFolders=/DataService/
	+SafeToDeleteExtensions=.xx1
	+SafeToDeleteExtensions=.xx2

Change 4190082 by Ben.Marsh

	Fixes to allow enabling edit and continue for Windows builds. Have experienced quite a few VS crashes when testing it in editor; not yet recommended for general use.

	- Allow edit and continue for any configuration, not just debug.
	- Fixed PDB errors compiling files that use a shared PCH with edit and continue enabled. Path to the generated PDB file was using the wrong directory.
	- Removed code that tracks PDB output files, since they're modified multiple times during a build.
	- Enable debug information when compiling generated CPP files, since it causes errors if the shared PCH PDB doesn't have the same option.
	- Disable support for remote execution of steps that modify the PDB, since the same file has to be modified many times. Remote execution causes the PDB files to be corrupted. Unfortunately, this makes E&C builds significantly slower.

	Add support for UnrealPak plugins.

	* Project and plugin modules can now specify an array of supported programs in the "WhitelistPrograms" field of their module descriptors, to allow modules to be loaded by programs.
	* Programs can now load any runtime modules, as long as they are whitelisted.
	* Programs under the engine directory can now use a shared build environment, so that building with a project file does not cause output binaries to be output to the project directory.
	* UnrealPak is now always built by default when packaging
	* Convert UnrealPak to a modular configuration

	UBT: Change the order in which Visual C++ toolchains are enumerated to prefer full releases over preview releases.

Change 4223318 by Ben.Marsh

	UBT: Add a build setting which allows creating a dedicated PCH for every file that's excluded from the unity working set (disabled by default). Improves iteration times when working on individual cpp files, but slows down iterating on header changes (and can take a lot of disk space for large changes).

	Dedicated PCH contains all includes scraped from the top of each cpp file, until a non-#include directive is encountered.

Change 4223401 by Ben.Marsh

	UBT: Add an option to automatically enable edit and continue for files in the adaptive non-unity working set. E&C doesn't seem very useful for UE4 projects right now; compile time is comparable to regular build times, but it can take several minutes to apply code changes for large projects.

Change 4223899 by Ben.Marsh

	UBT: Fix loading XML config files on Mono; Type.GetField(Name) does not seem to return values unless binding flags are specified.

Change 4224637 by Ben.Marsh

	Add a "SupportedPrograms" field to plugin descriptors, which allows plugins to declare which plugins they support independently of individual modules. Programs now respect the "bEnabledByDefault" setting in plugins.

	Plugins that are compatible with a program now need to list that program in the SupportedPrograms list, and whitelist any modules that should load for that program.

Change 4224710 by Ben.Marsh

	UBT: Consolidate functionality for UHT module setup in ExternalExecution.cs.

Change 4229817 by Ben.Marsh

	UBT: Modules must now explicitly specify the path to the header used to generate a PCH if one is desired, rather than the header being determined automatically by attempting to parse the source code. Now that PCHs are force-included anyway, this removes a lot of dependencies inside UBT.

	Add the Delete command to Perforce wrapper in DotNETUtilities.

Change 4234688 by Ben.Marsh

	UBT: Simplify handling of installed/precompiled builds. Settings for whether a folder is installed/read-only or not is now stored on the RulesAssembly instance, allowing multiple things to be configured separately and stacked together (eg. engine/enterprise/project). RulesAssembly.IsReadOnly() allows determining if a flie can be modified or not and replaces many previous IsXXXInstalledCalls(), and traverses the chain of assemblies.

Change 4234711 by Ben.Marsh

	UBT: Runtime dependencies can now be copied to output directories as part of the build. When adding a runtime dependency, an optional source location can be specified to copy from. Both the source and target paths can use variables can be used as part of the path, eg. $(OutputDir), $(ModuleDir), $(PluginDir).

	Example usage (from a .build.cs file):

	Remove assert that GLogConsole is set; it won't be for command line utilities that don't depend on ApplicationCore.

	#jira UE-62545

Change 4261831 by Ben.Marsh

	Fix compile errors due to missing include path when hot-reloading a module from the editor. There are not necessarily source files to compile when -modulewithsuffix is specified on the command line, which was results in GeneratedCodeWildcard not being set.

	#jira UE-62463, UE-62384

Change 4266019 by Josh.Adams

	- Fixed the CopyAction for runtime dependencies that need to be copied to different location, on non-XGE

Change 4266264 by Ben.Marsh

	Remove override for the __IPHONE_OS_VERSION_MIN_REQUIRED macro on TVOS.

	This macro is already defined by system headers (in <AvailabilityInternal.h>). Now that we support PCHs on IOS and TVOS, manually defining this macro results in it being defined three times (once for the PCH, once by AvailabilityInternal.h, and once by the force-included list of definitions for the source file being built). The errors for redefining the macro in AvailabilityInternal.h are suppressed due to it being a system header, but the error for redefining it for the source file being compiled are not.

	#jira UE-62578

Change 4266273 by Ben.Marsh

	Fixes incremental build failure when compile arguments for PCH have changed on IOS/TVOS. Compile action needs to have a dependency on PCH build action.

Change 4266614 by Graeme.Thornton

	Fix crash when cooking nativized blueprints due to removal of child cooker system.

Change 4266763 by Ben.Marsh

	Always build UnrealPak when building client targets. The ProjectParams.Pak option is not reliable, because it can be forced on later by the target platform.

	#jira UE-62584

Change 4267985 by Robert.Manuszewski

	When iterating with ForEachObjectWithouter, don't lock the entire has table but only the hash bucket that is currently being iterated

	#jira UE-62600

Change 4268558 by Robert.Manuszewski

	PurgeLegacyBlueprints will no longer be called from within ForEachObjectWithOuter is it renames objects that reside in hash tables that are being iterated over which may lead to undefined behavior.

	#jira UE-62600

Change 4269011 by Chad.Garyet

	- Fixing Wildcard match issue, the change to ugsapi sends projects as //Depot/Stream instead of //Depot/Stream/

Change 4275913 by Ben.Marsh

	Add a dummy exported symbol to the XGEController module, to fix build errors due to missing .lib file when it's built with WITH_XGE_CONTROLLER = 0.

Change 4284161 by Ben.Marsh

	Allow mirroring Oodle files to remote Mac.

Change 4074774 by Steve.Robb

	Vast simplification of TFunction, making it smaller in footprint, easier to follow and extend, and more correct.
	TUniqueFunction added, which is a move-only TFunction which can hold move-only functors.
	Fix for UWidgetBlueprint::ForEachSourceWidget() which should never have compiled but did.
	FFunctionGraphTask and TFuture<> updated to use TUniqueFunction to make them more general.
	TArray::HeapPop() made to work with move-only types.

Change 4082591 by Ben.Marsh

	https://blogs.msdn.microsoft.com/oldnewthing/20151008-00/?p=91411

Change 4091456 by Steve.Robb

	Unification of all platforms' FMath::CountTrailingZeros() and FMath::CountLeadingZeros() for both 32-bit and 64-bit.

Change 4156437 by Ben.Marsh

	Lots and lots of fixes compiling for Clang on Windows.

	Editor now compiles cleanly without warnings, but crashes on startup due to error in intrinsics test. Disabling that runs further, but crashes accessing freed memory. Switching to the ANSI allocator runs further, but crashes in Slate after the splash screen and before the editor window opens. // TODO!

	* Switching between Clang/ICL/VS2015/VS2017 is now supported through the same mechanism as switching Visual Studio versions, without requiring any source level changes. To use Clang, set WindowsPlatform.Compiler = WindowsCompiler.Clang from a .target.cs file, or set <WindowsPlatform><Compiler>Clang</Compiler></WindowsPlatform> from BuildConfiguration.xml. To pick a specific toolchain version, set WindowsPlatform.CompilerVersion.
	* Clang is now supported through AutoSDKs; will be added to CIS.
	* The Samples/Sandbox/Clang project forces Clang to be used from its target.cs file, and allows easily building all editor modules and plugins with Clang on Windows.
	* UnrealMathSSE intrinsics have been re-enabled for Clang due to missing functions from the UnrealMathFPU implementation, but causes failure in tests at startup.
	* SSE4_CRC32() is disabled in D3D12Pipelinestate.cpp, since intrinsics are only allowed if enabled for the whole target (rather than being used in specific functions due to runtime checks)

Change 4157389 by Ben.Marsh

	Few more fixes for compiling the editor with Clang.

Change 4183911 by Ben.Marsh

	Fixes to support incremental linking on Windows. Does not seem to have any net benefit right now; may improve once minimal rebuild is enabled.

	* Incremental linking no longer forces PDB files to be enabled for source files.
	* Actions can specify specific files to be deleted before each build. Code to forcibly delete PDB files has been moved to the MSVC toolchain.
	* Unused libraries produced by the cross-referenced link are no longer added as build products, since (a) deleting them breaks dependency checking for incremental linking and causes a full link, and (b) not deleting them breaks UBT dependency checking and causes actions to be run over and over again.
	* Icon update is disabled for Windows when incremental linking is enabled.
	* Removed rarely-used setting to always delete produced items before each build.

Change 4184311 by Ben.Marsh

	UGS: Added a dialog which shows all the required platform SDKs for a branch, linked from the status panel in UGS.

	The llist is configured via the UGS config file submitted to Engine/Programs/UnrealGameSync/UnrealGameSync.ini (and may be overridden by the project config file if necessary):

	    [Default]
	    ; Set this to a network share which contains the SDK installers for your site
	    SdkInstallerDir=

	    ; All the required SDKs for the current version of the engine
	    +SdkInfo=(Category="Android", Description="NDK r21", Browse="$(SdkInstallerDir)\\Android")
	    +SdkInfo=(Category="Windows", Description="Visual Studio 2017")
	    +SdkInfo=(Category="Windows", Description="Visual C++ Toolchain 14.13.26128")
	    +SdkInfo=(Category="Windows", Description="Windows SDK 10.0.16299.0")

	Similar entries for console platforms are added in console subdirectories. Each entry may contain an Install="Foo.exe" and/or Browse="C:\Foo" style attribute, specifying the path to an installer to run or directory to open in explorer respectively.

	The SdkInstallerDir setting is used as a base directory for the default installers, seen above for Android. Licensees may override this with a network path specific to the site that UGS is being deployed to (either in this file, in a project specific config file, or in a Engine/Programs/UnrealGameSync/NotForLicensees/UnrealGameSync.ini file).

Change 4200452 by Ben.Marsh

	UBT: Change DebugGame configurations to output a separate executable rather than requiring a -Debug argument at runtime. Previous behavior was a common source of errors.

	Engine modules are still shared between Development and DebugGame, but the launch module sets a flag in Core on startup indicating the game configuration.

Change 4206189 by Ben.Marsh

	UBT: Simplify logic for precompiling binaries.

	* Target no longer has separate list of "precompile only" binaries or modules. New -AllModules option allows adding every module to a target, which can be used with -Precompile and -NoLink to precompile object files for monolithic builds.
	* Precompiled file lists have been removed from target receipts.
	* The manifest now includes all generated headers and precompiled files when run with the -Precompile option.
	* Separate -DependencyList=Foo.txt has been added to write a list of all dependencies required to use precompiled binaries. This file list can be read using the <Tag> task in buildgraph.

Change 4215466 by Ben.Marsh

	UBT: Remove indirect calls to determine extensions for object files and precompiled headers. The toolchain knows the correct convention for the platform.

Change 4215975 by Ben.Marsh

	UBT: Remove telemetry code. This has never proved useful for analyzing performance due to the number of incidental factors that affect build times (eg. number of files being compiled).

Change 4220154 by Ben.Marsh

	Move text-only implementations of FOutputDeviceError back into Core, so we can build command-line applications that don't depend on ApplicationCore.

Change 4224708 by Ben.Marsh

	Add a bCompileAgainstApplicationCore setting to the target rules, which allows compiling out references to the ApplicationCore module (which should only be necessary for applications with a GUI). Removed ApplicationCore from several engine tools and utilities.

Change 4224958 by Ben.Marsh

	Remove CoreMinimal.h includes from Core.

Change 4229059 by Ben.Marsh

	UBT: Remove the UEBuildPlatform.ShouldNotBuildEditor() hook for target platforms. We shouldn't be modifying a target's build environment to disable the editor; it is invalid to build the editor for these target platforms at all, and this is already enforced by the GetSupportedPlatforms() function.

Change 4230508 by Ben.Marsh

	Fixup precompiled header setting for samples and games.

Change 4231457 by Ben.Marsh

	Fix exceptions in log messages having trailing newlines.

Change 4232406 by Ben.Marsh

	UBT: Always force include a PCH for generated code if there's one set; the code may depend on it to compile.

Change 4234177 by Ben.Marsh

	Set up private PCH files everywhere that previously used them.

Change 4235973 by Ben.Marsh

	Change FPlatformMisc::GetEnvironmentVariable() to return an FString() rather than requiring a fixed size buffer to be passed in. Removes references to MAX_PATH.

Change 4238842 by Ben.Marsh

	Add support for paths longer than MAX_PATH in the editor. Requires Windows 10 version 1607, and the functionality to be enabled via a registry key or group policy (see https://docs.microsoft.com/en-us/windows/desktop/FileIO/naming-a-file).

	Only a subset of Win32 functions support long paths (executables can only be started from paths shorter than MAX_PATH, for example).

	* Added a FPlatformMisc::GetMaxPathLength() function to return the maximum length of a path on the current system. On Windows, this returns a different value for systems with long paths enabled to those without.
	* The MAX_PATH define is no longer set by non-Windows platforms. Instead, there is a MAC_MAX_PATH, UNIX_MAX_PATH, etc... for any platform-specific code that still relies on the previous macro.
	* The MAX_UNREAL_FILENAME_LENGTH macro has been renamed to MAX_UNREAL_FILENAME_LENGTH_DEPRECATED
	* The PLATFORM_MAX_FILEPATH_LENGTH macro has been renamed to PLATFORM_MAX_FILEPATH_LENGTH_DEPRECATED.
	* Removed custom resource files for programs, since they are just copies of the base UE4 one (which is used by default anyway). The base UE4 manifest declares support for long paths.
	* Fix 512 character maximum length on editor commands.

	260 character limit remains in place for cooking at the moment (see ContentBrowserUtils.h), until C# staging code supports long paths.

Change 4255042 by Ben.Marsh

	UBT: Remote compilation now uploads the entire workspace to the remote Mac and executes a separate remote instance of UBT rather than synchronizing individual actions. This makes the remote compile codepath much simpler, and removes a lot of special cases that exist to support it previously.

	The list of files to be transferred to the remote are listed as rsync filter rules in Engine/Build/Rsync/RsyncEngine.txt and RsyncProject.txt, which are applied to the root engine directory and project directory respectively. Projects that need to customize which files are uploaded can add their own <ProjectDir>/Build/Rsync/RsyncProject.txt file, which will be included in the filter before the default version.

Change 4260567 by Ben.Marsh

	UAT: Rename CommandUtils.Log to CommandUtils.LogInformation, to avoid conflicts with the underlying Tools.DotNETCommon.Log class.

	Fixup BuildPhysx to only set up HTML5 when needed.

Change 3812325 by Jake.Leonard

	Fix keyed debug messages from getting scaled to 0 and thus not appearing at all. This appears to be a bug in main as well. Only -1 keyed messages (which are handled differently) will display anything at all as the scale application was removed.

	#Jira UE-53579

Change 3828032 by Jon.Nabozny

	Make sure the State is set before triggering delegates in FLwsWebSocket.

Change 3837391 by John.Barrett

	NetcodeUnitTest updates for better CIS/automation support.

Change 3837392 by John.Barrett

	Fixed performance issue with processing piped output for large numbers of unit tests, and fixed unit test windows overlapping - plus other bugfixes.

Change 3837397 by John.Barrett

	Moved a unit test to the 'Obsolete' folder.

Change 3837476 by John.Barrett

	Reduced unwanted OSS-null logspam.

Change 3844506 by Jake.Leonard

	Implementing missing steam leaderboard implementations. Also streamlines and fixes the friends leaderboard too.

	#Jira UE-53474,UE-53475,UE-53476

Change 3844803 by Jake.Leonard

	Fixing the Steam Leaderboard to allow for overwrite instead of increment.

	Please see Jira for recent comments

	#Jira UE-24791

Change 3844829 by Jake.Leonard

	Does the following:

	* Add message on the screen while the presence test is running to let users know that the test is still running.
	* Remove the FUniqueNetIDString dependencies in the test
	* Fix the Steam Rich Presence from having to do an unnecessary cast

	#Jira UE-53066,UE-54177

Change 3851997 by Jake.Leonard

	Remove one of the double steam p2p dump prints. Now the socket subsystem is the only one that prints, which will cover more cases anyways and limits the potential of duplicate prints.

	Also changes the dump interval to 10s from 3s.

	#Jira: UE-53763

Change 3882307 by John.Barrett

	Fixed packet flooding protection, and handling of packets with errors, so that they don't delay further packet processing.
	When there's an error receiving a packet, make sure the wrong/previous-packets address isn't used for logging.

Change 3882311 by John.Barrett

	Restricted socket recv code from CL 3026398/3209824 to TCP, as with UDP it prevented telling the difference between the socket having no data to receive, and receiving a 0-length UDP packet.

	This is important for protecting against DoS attacks.

Change 3894785 by Jake.Leonard

	Fix replays not ending properly when the user goes to end their PIE instance.

	#Jira UE-54488

Change 3902627 by Jake.Leonard

	Fix the demo time values being incorrect if our delta would push us to the end of the replay. Since we're done, we early out of the functions before we have a chance to update the DemoCurrentTime variable. This causes issues with UI elements as it looks like the replay is not over but it actually is.

	#Jira UE-54483

Change 3902632 by Jake.Leonard

	Fix voice issues on seamless travel for NullOSS

	#Jira UE-54899

Change 3904775 by Jake.Leonard

	Properly grab the correct world context (we were sometimes grabbing the editor instead, when we wanted the PIE world). These changes will allow us to reliably end the demos. Improves the fix in 3894785.

	#Jira UE-54488

Change 3968022 by Ryan.Gerleve

	PR #4538: Guarantee Return Value of 0 When GetPortNo() Fails (Contributed by XenonicDev)


Change 3994505 by Jake.Leonard

	Fix some shootergame minor bugs:

	1. If there's no map selector UI option, just search for all maps. This fixes the only seeing Sanctuary bug (first option in the maplist)
	2. Always make the server push gametype (which is just TeamDeathmatch by default)

	#Jira none

Change 3999511 by Jake.Leonard

	FArchive serializer for FUniqueNetIdSteam

	#Jira none

Change 4014550 by Jake.Leonard

	Fix Steam Dedicated Server from linking steamclient dlls, which should not be necessary.

	This fix introduces a new launch argument (-force_steamclient_link) that can be used to force the steamclient link anyways for licensees who might have required this under extreme circumstances.

	#Jira UE-55183

Change 4017165 by Jake.Leonard

	Modification of the leaderboard test interface to add more tests as well as arbitrary rank fetches.

	Command is "online test leaderboards [optional arbitrary user id for lookup]"

	#Jira UE-53533

Change 4017215 by Jake.Leonard

	Fix MULTIHOME returning the incorrect ip address on Linux and Android

	#Jira UE-57463

	#jira none

	#AUTOMERGE using branch FNMain->DevNetworking of change#3877681 by Brian.Bekich on 2018/02/07 16:52:11.

Change 4024131 by Ryan.Gerleve

	[+] Add -csvdemostarttime and -csvdemoendtime command line arguments to automate CSV profiles when running replays. Since these commands use the playback time of the replay, they are much more reliable than the loading screen method we used previously.

	Replication Graph v1. This is the new system for dedicated server performance in BR. It is currently disabled by default. Other changes to engine should have no practical impact on existing behavior.

	#jira nojira

	Engine Changes Summary
	-------------------------------------------

	UNetConnection::>ActorChannels no longer public. This is to prevent code from adding/removing actor channels from underneath the ReplicationDriver.

	UActorChannel::Close() returns int64 for num bits written. int64 is used because that is what FBitWriter uses.

	UNetconnection::DestroyedStartupOrDormantActorGUIDs now private. Add/Remove/Reset methods are exposed. This is so RepDriver can intercept these calls (when present).

	Added USimulatedClientNetConnection. Use net.SimulateConnections command to add them.

	New UNetDriver::ForceNetUpdate function. Notifies replication driver that force net update was called.

	UNetDriver::DestroyedStartupOrDormantActors now wraps the FActorDestructionInfo in TUniquePtr. This is so pointers to destruct infos are stable within the map and rep driver can keep track of them in its own list.

	UNetDriver::GetFunctionRepLayout exposed as ENGINE_API for RepDriver use.

	UNetDriver::ProcessRemoteFunction changes a bit.
	-Forwards to RepDriver if present. The intention is to give RepDriver the chance to change routing logic and do its own traffic bookkeeping on the RPC.
	-A new function, ProcessRemoteFunctionForChannel exists for the meat of the RPC call which RepDriver probably doesn't want to change and is free to call.
	-Removed FRepLayout::SendPropertiesForRPC first UObject parameter because it was not used.

	New function UNetDriver::NotifyActorDormancyChange for when actor dormancy changes.

	New Functions UNetDriver::AddNetworkActor/RemoveNetworkActor. These forward to the rep driver if present.
	-Really want to get rid of public access to GetNetworkObjectList() outside of net code. Doesn't seem easy without breaking backcompat.

	New Function UNetDriver::NotifyActorTearOff for when tear off happens.
	-bTearOff is public though. RepGraph requires the explicit TearOff() call to notify the system about tear off actors. I'm not sure how to fix this with deprecation warnings. (Keep variable public but warn if accessed)

	New UNetDriver::RemoveClientConnection function should be the only place that removes ClientConnections. Forwards to RepDriver.
	-Again, would like to make ClientConnections private but it is used all over the place. (Thankfully only one place removes from it).

	New UNetDriver::NotifyActorFullyDormantForConnection. So RepGraph can intercept and do its book keeping.

	Made UNetDriver::IsLevelInitializedForActor public.

	Made UNetDriver::FlushActorDormancyInternal to hold common code that happens when Dormancy is flushed or changes.

	FNetworkObjectList::FindOrAdd has optional bool parameter for if actor info was actually added.

	UWorld has new delegates for when all starting actors are initialized and registered with networking.
	-TODO: NavSystem and AI system should make use of this. The currently has direct function calls into them.

	Moved checks for bPendingDormancy/Dormant into UActorChannel::StartBecomingDormant rather than at the callsite(s).

	Added GReplicationGatherPriortizeTimeSeconds, GServerReplicateActorTimeSeconds, GReplicateActorTimeSeconds, GNumReplicateActorCalls. These are for new Replication CSV stat group (disabled by default).

	FObjectReplicator::QueueRemoteFunctionBunch drops MustBeMappedGUIDs if it suppresses the RPC call. This fixes a bug that exists in both systems.

	UWorld::SpawnActor now adds network actor after PostSpawnInitialize rather than prior. This is so the initial location of the actor can be used.
	-Deferred actor spawning can still make this not the case, but without this change there is no chance of the actor location being correct.
	-In this case, I care about this for FN building actors who do not use deferred spawning.

	Added STAT_NetServerGatherPrioritizeRepActorsTime which is the total Server Rep Actor time minus the time spent in ReplicateActor.

	-Removed STAT_NumRelevantActors because it made no sense (set to whatever connection repped last).
	-STAT_NumReplicatedActors now sum of replicated actors on all connections for the frame.
	-STAT_NumReplicatedActorBytes now sum of replicated property bytes on all connections per frame. Does not track package map guid bytes.

	-FRepLayout BuildSharedSerializationForRPC/ClearSharedSerializationForRPC exposed as ENGINE_API for RepGraph to use.

	Non Networking Engine Changes:
	Added optional RenderColor parameter to K2_DrawBox.

	ULevel::HasVisibilityChangeRequestPending and ULevel::IsNetActor exposed as ENGINE_API so ReplicationGraph module can call it.

	Added AHUD::OnHUDPostRender callback for easier debug huds that don't revolve around players or debug actor targets.

Change 4024394 by Ryan.Gerleve

	Fix crash in rep graph when spatialization gets rebuilt while dormancy actors were in a particular state.

	Dormancy nodes still had delegates registered for their contained actors. Though they dumped the list of actors, they would still get notification when the actors' dormancy changed which would cause them to readd the actors some times. If these nodes overlapped between rebuilds, actors could get readded to the same node twice which ultimately leads to them not being fully removed when they do get destroyed, and garbage AActor* trying to replicate. Net.RepGraph.Verify can catch these problems.

	To fix, we are going to MarkPendingKill the GridCell nodes rather than keeping them around and just reseting their actor lists. They will get recreated as needed.

	They could have also manually unregistered each of their delegates but this is more complicated and probably performs worse overall (though spatial rebuild is rare/should never really happen in a  real game). Just marking the uobject pending kill will suppress the delegate callbacks to the nodes.

	Replication Graph. These are mostly for engine related purposes/cleanup.

	-Don't remove TornOff actors from rep graph when they are destroyed. They are removed when they are torn off already. Fixes benign log warnings.
	-When an actor causes spatialization rebuild, set the bias such that the actor is in the middle of new cell. This mitigates the issue where spatialization would be rebuilt every frame once an actor moves "away from the grid".
	-When rebuilding spatilization, force garbage collection after tearing down old nodes. This is to mitigate OOMs. You are already going to hitch because of the rebuild anyways.
	-Removed some dead/debug code that isnt needed.

	When BP clustering is enabled, make sure to add the template to the BP cluster when replacing it.

Change 3853797 by Ben.Marsh

	BuildGraph: Add a <Trace> element, which allows logging messages after the string is parsed (as opposed to the Log task, which logs them at runtime). Useful for debugging macro expansion, etc...

	Also add a -showdiagnostics parameter, to have diagnostic messages output even when running with the -listonly option.

Change 3857540 by Graeme.Thornton

	Properly process the uexp file for a umap asset when generating a pak patch. Stop those uexp files being included in the patch even when they haven't changed

Change 3860062 by Steve.Robb

	Fix for FString::Reset()'s buffer not being an empty null-terminated string (affects FString::ParseIntoArray, for example).

Change 3860138 by Steve.Robb

	Fix for FString::ParseIntoArray() for when string memory has been allocated but has no characters.

Change 3860273 by Steve.Robb

	Tidy up of FHotReloadClassReinstancer::FCDOWriter to not do stuff in constructors.

Change 3863203 by Steve.Robb

	Crash fix for UObjects whose constructors are defined as = default;, which would re-null the UObject state (ClassPrivate, OuterPrivate etc.).

	See: https://udn.unrealengine.com/questions/412930/crash-due-to-default-constructor.html

Change 3864588 by Graeme.Thornton

	Crypto Keys Improvements
	 - Removed UAT command line params for encryption. Centrally configured by the editor settings now.
	 - UAT staging now creates a small json file containing the keys and settings used for encryption and signing and stores it in the build metadata
	 - Minor refactoring of UAT encryption processing to use the new cryptokeys json file
	 - UnrealPak can be told to get its encryption settings from a json crypto file with the "-CryptoKeys=<filename>"
	 - UnrealPak can now accept a "PatchCryptoKeys=<filename" parameter which gives it a filename to a cryptokeys json file that it can use to unpack the patch reference paks

Change 3864691 by Robert.Manuszewski

	Don't add objects that are in root set to GC clusters to prevent them from keeping the clusters alive forever.

	Serializing object will now be passed to GC so that it can be logged in case the referenced objects is garbage.

Change 3874413 by Steve.Robb

	Algo::MinElement and Algo::MaxElement, for finding the minimum and maximum element in a range, and *By versions which take projections.
	TRangePointerType moved to its own file and used in Algo::MinElement and Algo::MaxElement.

Change 3874457 by Ben.Marsh

	When spawning child processes, only allow them to inherit the writable ends of the stderr and stdout pipe. Fixes an issue related to AutomationTool hanging when the editor closes after running automation tests.

	The editor launches ADB.EXE (Android Debug Bridge) on editor startup, which forks itself to initialize a server. Even though the child process has its own stdout and stderr pipes, it also inherits the pipes for the editor. When run from C#, as we do for automation tests, Process.WaitForExit() waits for all pipes to be closed before returning. This can't happen if the forked ADB instance still has a reference to the editor's pipes.

Change 3876435 by Robert.Manuszewski

	Don't add root set objects to level actor container to prevent situations where clusters are kept alive forever

Change 3878762 by Robert.Manuszewski

	Fixing potential LinkerLoad leak when a package that still has a linker associated with it is being destroyed.

	UGS: Change modal dialog to regular window style to avoid weird alignment issues under Windows 10.

Change 3887500 by Ben.Marsh

	UGS: Add support for grouping build badges by a prefix. Badges such as "Foo:Bar1", "Foo:Bar2" will be grouped together (with "Foo:" stripped from the displayed badge names).

	Also add a separate column showing the type of each change, rather than including it in the CIS column, and change badges to a more angular Windows 10 style.

Change 3887513 by Ben.Marsh

	UGS: Fix badge text drawing outside the clipping bounds.

Change 3888010 by Josh.Engebretson

	Fix UVS logging to UnrealVersionSelector/Saved/Logs and instead use project's log path
	#jira none

Change 3888418 by Ben.Marsh

	UGS: Add a cache for computed badge layout information. Improves responsiveness when redrawing.

Change 3889457 by Steve.Robb

	GitHub #4457 : Display abbreviations properly when converting FNames to display string

	#jira UE-54611

Change 3889547 by Ben.Marsh

	UGS: Add an extensible method for adding arbitrary badges to the right of the "description" column, by running a regular expression over the changelist description.

	Epic uses a "#tag" style annotations in changelist descriptions and Perforce triggers to verify them. "#jira" is used to link a changelist to an issue tracked in Jira, for example. A matcher to add a badge next to every changelist with a #jira tag, and link to the corresponding issue in Jira, could be set up with an addition to the project's Build/UnrealGameSync.ini file like this:

	[Badges]
	+DescriptionBadges=(Pattern="(?i)#\\s*jira\\s*:?\\s+([A-Za-z]+-[0-9]+)", Name="$1", Group="Jira", Color="#c0c0c0", HoverColor="#e0e0e0", Url="https://jira.it.epicgames.net/browse/$1")

	The "Pattern" attribute specifies the regex to match, and may capture portions of the matched text to be substituted later. "Label" specifies the label to appear on the badge. "Group" specifies an arbitrary identifier used to group related badges together rather than separating them with whitespace. "Color" and "HoverColor" specify hex RGB colors for the badges. "Url" specifies the path to open with a C# Process.Open call if the badge is clicked.

Change 3889726 by Ben.Marsh

	UGS: Fix description badges that don't have any associated URL.

Change 3889995 by Ben.Marsh

	UGS: Fix issue where popup menus can create top level windows in the taskbar. Seemlingly caused by capturing mouse before the window has been activated - removed capture code, and replaced with handling of OnMouseLeave() event instead.

Change 3890007 by Ben.Marsh

	UGS: Add a caption underneath the project logo which shows the current stream, to make it more obvious.

Change 3890057 by Ben.Marsh

	UGS: Fix repainting glitch when resizing window; bounds for status panel lines was not being reset correctly.

	Back out changelist 3881331 because it's causing cook errors.

Change 3891100 by Ben.Marsh

	UGS: Add support for a per-branch "message of the day"-style feature. Messages can be specified in a project's config file in Perforce (eg. <ProjectDir>/Build/UnrealGameSync.ini) as follows:

	[//UE4/Main/Samples/Games/ShooterGame.uproject]
	Message=:alert:  Lockdown for fixes is **5pm on Friday**. Only fixes for the 2.0 release should be submitted to this branch. [34 issues](https://jira.it.epicgames.net) are remaining as of 2/15.

	A limited subset of Markdown is supported: [web links](http://www.google.com), *italic*, _italic_, **bold**, __bold__. Icons will be supported through :icon: syntax; the only icon currently available is :alert:

	Re-removal of SetShouldHandleAsWeakRef, which was originally removed in CL# 3437205.

Change 3895872 by Ben.Marsh

	UGS: Show the stream name in tab labels by default.

Change 3896366 by Ben.Marsh

	UGS: Automatically resize columns when the main window is resized, and allow specifying desired column widths for projects that have a large number of CIS badges.

	Columns are now resized proportionally, clamped to a minimum size. Columns will automatically expand up to a desired maximum size, though can be explicitly resized larger if necessary. Columns will not be resized if they are already larger than the window can show, or smaller than the window has space to show.

Change 3896367 by Ben.Marsh

	UGS: UI tweaks - change and time columns are now centered, "Unknown" badge is displayed until a change's type has been determined, increase height of status panel.

Change 3896425 by Ben.Marsh

	UGS: Speculative fix for race condition on clients displaying "under investigation" state. If the DB event is received before a change where an investigation is cancelled is polled from Perforce, we will exclude the resolve event from the list of active investigations.

Change 3896461 by Ben.Marsh

	UGS: Add an option to allow setting a tint color to be applied to the status panel, to allow identifying streams more easily. To use, add a setting similar to the following to a project's Build/UnrealGameSync.ini file:

	[//UE4/Main/Samples/Games/ShooterGame/ShooterGame.uproject]
	StatusPanelColor=#dcdcf0

Change 3899530 by Ben.Marsh

	Add unified syntax for overriding branch specific settings. Checks branch settings first, then [Default] section.

Change 3901164 by Ben.Marsh

	UGS: Add a class to store all the resources for the status panel.

Change 3901165 by Graeme.Thornton

	TBA: Attempt #2 at submitting the text asset saving code. SavePackage rejigged to write all header information in terms of FStructuredArchive, with all exports written through an FArchive adapter. Minimal amount of structured archive serialization functions added to allow this data to be written

Change 3901301 by Ben.Marsh

	UGS: Add support for reading the latest version of the project config file from Perforce. Some settings should be read depending on the CL you are synced to (eg. build steps), whereas others (MOTD, branch status) should always use the latest version. Will read the local version if checked out, to allow testing local changes.

Change 3902454 by Ben.Marsh

	UGS: Fix logo not being redrawn in the correct position when starting to sync.

Change 3903416 by Ben.Marsh

	UGS: Group badges explicitly through INI file rather than by expecting name to contain ':'.

	#jira UE-55442

Change 3904648 by Ben.Marsh

	UGS: Remove files from the workspace that are excluded by the sync filter.

	The user's config file stores a hash of the last sync filter. During syncing, if this hash doesn not match the previous value, we enumerate all the files in the #have list and remove anything masked out by the filter.

	#jira UE-47335

Change 3905442 by Steve.Robb

	Change of the ConvertFromType() multi-bool return value to a more descriptive enum.
	Some return values here do not make sense - this is because the existing logic is being preserved and will be fixed in a separate change.

Change 3905629 by Ben.Marsh

	UGS: Fix race condition between two child processes starting on different threads, and inheriting the other's intended stdout/stderr pipes. This prevents pipes being closed when one of the child processes shuts down, and causes waits on the read ends of those pipes to continue indefinitely.

There are a large number of small files required for it to run with loose files, which takes a lot of space on disk (due to cluster sizes), and is unweildy to move around.

	CrashReporter UFS files are tracked in a separate dictionary to regular UFS files to allow construction of the additional PAK file.

Change 3921002 by Ben.Marsh

	UGS: Add option for syncing all projects in a branch. Off by default. Also add support for masking in additional paths to be synced (eg. one or two extra projects).

	UAT: Add *Encryption.ini to the list of auto-blacklisted config filenames

Change 3924604 by Graeme.Thornton

	UnrealPak: If encryption keys are parsed and fail the encrypt/decrypt test, throw a fatal error. The exectutable will have those same keys embedded so there is no point allowing the paks to be created with broken keys.

Change 3924638 by Graeme.Thornton

	Crypto: Improvements to parsing of old fashioned encryption.ini settings:
	 - AES keys that are too long or short (need to be 32 bytes) will now emit a warning when being parsed, and be truncated or expanded before adding to the crypto settings.
	 - Signing keys will emit an error when they are too long (>64bytes)
	 - Unrealpak will still assert when invalid settings are passed via the other mechanisms (command line or -encryptionini mode). Settings via the crypto json file should now be sanitized and not cause issues

Change 3942404 by Graeme.Thornton

	Pak Signing:
	 - Unify naming of pak precacher and signedarchivereader signature check functions to make it easier to search for them in crash reporter
	 - Format the signedarchivereader output to match the pak precacher
	 - When signedarchivereader detects a signature check, do the same master signature hash check that the pak precacher does to confirm that the .sig file contents haven't been corrupted since load.
	 - Add PAK_SIGNATURE_CHECK_FAILS_ARE_FATAL guarded exit to signedarchivereader signature failure
	 - Optimization for pakprecacher signature checks. Instead of locking the cached files mutex for every decoded signature, take a local copy in blocks of 16. Only re-lock if we need more. Grab the initial batch when setting up. In most cases, reduces the number of locks to 1 per signature check call.

Change 3942825 by Ben.Marsh

	UAT: Allow passing -Project<N>=Foo.uproject arguments to the MegaXGE commandlet (eg. -Target1="ShooterGame Win64 Development" -Project1="D:\ShooterGame\ShooterGame.uproject") so it can be used from an installed engine build.

Change 3947359 by Graeme.Thornton

	TBA: Fixes to loading code to allow bulk data to get a pointer from its loader archive to an archive that it can load from at a later date. For binary archives, this is just a pointer back to the same archive, but for text assets it is a pointer to a "child reader" which maintains its own structured archive that is scoped to the current location in the file.

Change 3947360 by Graeme.Thornton

	TBA: Added RoundTrip mode to text asset commandlet. Performs determinism tests in project assets to see whether they save deterministically to binary and text files, and also when they are ping-ponged between the two formats.

Change 3954694 by Ben.Marsh

	BuildGraph: Add support for user-defined macros, which can contain a list of buildgraph commands and be expanded within a node. Example script in Engine/Build/Graph/Examples/Macros.xml.

	To define a Macro, use the syntax:

		<Macro Name="MyTestMacro" Arguments="PrintFirstMessage;PrintSecondMessage" OptionalArguments="PrintThirdMessage">
			<Log Message="First message" If="$(PrintFirstMessage)"/>
			<Log Message="Second message" If="$(PrintSecondMessage)"/>
			<Log Message="Third message" If="'$(PrintThirdMessage)' == 'true'"/>
		</Macro>

	To expand a macro, use the syntax:

		<Expand Name="MyTestMacro" PrintFirstMessage="true" PrintSecondMessage="true"/>

	An error will be thrown if any required arguments are missing. Optional arguments default to empty if not specified.

	Tasks within a macro are validated by the schema at the point of definition using the same rules as apply to a <Node> element, but properties are not evaluated until the macro is expanded. This allows macros to get and set properties in scope at the point that it is expanded. Local properties that are introduced within a macro do not otherwise leak to the scope that they are expanded.

	TBA: Text asset loading/saving work
	 - Start using FStructuredArchive flavours of UObject Serialize functions when loading and saving exports.
	 - Only use FStructuredArchive interface for text assets, and for classes that have the CLASS_MatchingSerializers which tells us that the class can serialize to both FStructuredArchives and FArchives.
	 - Add GetCacheableArchive to FArchive, which allows transient archives to return a pointer to another archive that will outlive it. Used by bulk data to get a pointer to an archive that can be held and used at a later time to lazy load things. For text assets where the bulk data might be held inside a base64 encoded FArchiveFromStructuredArchive block, we can't dynamically seek back to that location after the on-stack wrapper has been destroyed after the original serialize, so this will return null. For binary assets, we just return a pointer to the same binary archive which can be used freely.

Change 4007458 by Ben.Marsh

	UBT: Change RPC utility to abort early, rather than continue to try to build even though SSH init failed.

Change 4009343 by Ben.Marsh

	UGS: Set the rmdir option on new workspaces by default.

Change 4009501 by Ben.Marsh

	UBT: Add Windows include paths to the compiler command line, rather than setting through environment variables. This ensures that incremental builds work correctly when SDK versions change.

Change 4009509 by Ben.Marsh

	UBT: Check in a non-versioned directory under the Windows 10 SDK for the resource compiler.

Change 4010543 by Ben.Marsh

	Remove the "Device" and "Simulator" platform groups, because they're unused and overly generic for folder names. Also remove source code for the HTML5 simulator (which is no longer supported).

Change 4010553 by Ben.Marsh

	UAT: Include platform groups in restricted folder names when staging.

Change 4012030 by Ben.Marsh

	UGS: Increase the size of the main window, and set the current stream as the default when creating a new workspace.

	Update message about downloading a new version of Visual Studio.

Change 4022063 by Ben.Marsh

	UBT: Suppress toolchain output when generating project files.

Change 4023248 by Ben.Marsh

	Install an unhandled exception filter to ensure we get crash reports from threads that are not spawned by the engine. At the moment, we only receive crashes that are routed through ReportCrash() via our structured exception handlers in WinMain() and FRunnableThreadWin::Run().

	(Also fix an exception within the exception handler, if GError has not been created yet)

Change 4025759 by Ben.Marsh

	UBT: Add additional logging for enumerating Windows SDKs.

Change 4026708 by Ben.Marsh

	UBT: Keep a separate list of installed Universal CRT versions to the list of Windows 10 SDK versions. It's possible to install C++ support without the Windows 10 SDK, which still includes UCRT files in Windows 10 SDK folders.

Change 4029404 by Ben.Marsh

	Remove incorrect include paths to fix CIS warnings.

Change 4031517 by Steve.Robb

	Fix for UHT errors not being clickable in the Message Log.

Change 3838569 by Steve.Robb

	Algo moved up a folder.

Change 3848581 by Robert.Manuszewski

	Changing the UObjectArray to not be allocated up front but in 64K-FUObjectItem chunks. This is to fix strange OOM reports on editor startup where it's trying to allocate space for 1M+ FUObjectItems.

	#jira UE-49446

Change 3864743 by Steve.Robb

	Fix for buffer overrun when copying a context string.
	Fix for being unable to link to MallocLeakDetection.
	Fix to prefix for FMallocLeakDetection::ContextString.
	New MALLOCLEAK_SCOPED_CONTEXT macro to push/pop a context string.
	Overload for const TCHAR* added to FMallocLeakDetection::PushContext to save on redundant memory allocations.

	#jira UE-54612

Change 3865020 by Graeme.Thornton

	TBA: Changed FIELD_NAME macro to FIELD_NAME_TEXT so that FIELD_NAME can be used for non-literal name definitions

Change 3910012 by Ben.Marsh

	UGS: Show an error window and allow setting default P4 server settings if syncing UGS fails.

Change 3920044 by Graeme.Thornton

	TBA: Text asset loading

	* Added a structured archive layer to FLinkerLoad
	* Wrapped export loading in a ArchiveUObjectFromStructuredArchive
	* Updated TextAssetCommandlet to have a "loadtext" mode which will try to load every text asset in the project content
	* Changed text asset extensions to .utextasset and .utextmap. Couldn't go with the favourite .uasset.json because our various path functions (FPaths::GetCleanFilename etc.) will only strip one layer of extension, so leave a bogus filename.
	* Relaxed a few checks in structured archive where it was checking for field reentrance, which isn't a problem for loading.
	* Changed FArchiveFromStructuredArchive to not load all referenced objects at construction time. This introduced some changes to load order which don't work in the engine. Object names are resolved at the point that a reference to them is serialized from the main data block, same as with legacy archives.

Change 3921587 by Steve.Robb

	Static asserts inside ensureMsgf() macros to prevent them being passed invalid arguments or non-literal formatting strings.
	Fixes for various misuses.

	#jira UE-55681

Change 3942873 by Ben.Marsh

	UBT: Allow link time code generation on any configurations where bAllowLTCG is set to true. Microsoft platforms were previously only allowing this option in shipping; the target can decide when to enable it or not.

Change 3944629 by Graeme.Thornton

	Merging back a couple of fixes from Fortnite
	 - Extra parenthesis around some calculations in the pakprecacher
	 - Changed FChunkCacheWorker::DoSignatureCheck() back to ::CheckSignature()
	 - Added documentation for build script crypto options

Change 3945381 by Ben.Marsh

	Disable warning C4770 on Windows (partially validated enum 'xxx' used as index), which occurs when enabling LTCG. Can't find a reference online for this warning, but I suspect it's due to LTCG allowing the compiler to trace code paths where we don't validate that an enum is a known value.

Change 3968969 by Steve.Robb

	Fixes to incorrect uses of FScriptMapHelper and FScriptSetHelper, which weren't accounting for gaps in the sparse array.

Change 3969417 by Ben.Marsh

	Make Visual Studio 2017 the default compiler for UE4 projects, and add support using Visual C++ toolchains from an AutoSDKs.

	Also add support for selecting a specific toolchain version to use through the WindowsPlatform.CompilerVersion property, which can be configured via a Target.cs files or BuildConfiguration.xml (eg. <WindowsPlatform><CompilerVersion>14.13.26128</CompilerVersion></WindowsPlatform). As well as allowing a specific version number, you can always use the latest toolchain by setting it to "Latest".

Change 3972443 by Ben.Marsh

	Change build scripts to allow running any steps on non-compile workspaces. Setup Dev-Core to just use a non-compile Win64 workspace for everything.

Change 3977198 by Ben.Marsh

	Remove INI file override for editor stack size on Windows. This is rarely valid since editor targets share build products with other games by deafult. Fix to add linker response file as prerequisite exposed targets overriding this as a bug.

Change 3979632 by Ben.Marsh

	Consolidate codepaths for embedding versioning information in the engine. Engine/Build/Build.version is now the authoritative place to read version information; Engine/Source/Runtime/Launch/Resources/Version.h no longer includes macros for the current branch and changelist.

	* Settings from Build.version are compiled into the (tiny) BuildSettings module via macros set in BuildSettings.build.cs, which is used to initialize version information inside the engine at runtime.
	* The IsPromotedBuild value is now set to zero by default (but set to 1 by the UpdateLocalVersion UAT command).
	* The -Licensee argument to the UpdateLocalVersion UAT command, and the IsLicenseeVersion setting for UnrealGameSync, is determined automatically by looking for the Engine/Build/NotForLicensees/EpicInternal.txt file. This path is not visible to licensees.

Change 3981738 by Ben.Marsh

	Move utility classes for filtering files and matching wildcards into DotNETUtilities.

Change 3983888 by Steve.Robb

	Warning C4868 disabled, about evaluation order of braced initializer lists.

	https://udn.unrealengine.com/questions/426081/help-with-error-c4868-braced-initializers.html

Change 3984019 by Steve.Robb

	FString::Printf formatting argument checking added.
	Vararg support for FText::Format.
	All remaining usage fixed.

Change 3985502 by Steve.Robb

	Change to TFunction debugger visualization to allow right-clicking on the [Lambda] and selecting 'Go To Source Code'.

Change 3985999 by Graeme.Thornton

	TBA: Serialize function generation for FArchive and FStructuredArchive overloads on a UObject, using UHT.
	 - Adds a restriction that UObject::Serialize() functions MUST be declared outside of any conditional compilation directives, except for WITH_EDITORONLY_DATA

Change 3986461 by Ben.Marsh

	Fixup lots of platforms not adding response files as a prerequisite.

	This can cause incremental builds to fail if input files/compile arguments change, because the action graph does not know that the response file being updated invalidates the build artifacts.

Change 3990081 by Ben.Marsh

	Remove custom output formatters for errors and warnings. These are not well supported by different executors, and cause fences between actions with the same formatter with external executors like XGE.

	Clang supports -fdiagnostics-format=msvc for all platforms, which should do a better job than our crude attempts at regexing errors (causing botched output in some cases).

Change 3996714 by Chad.Garyet

	UGSRestAPI, conversion of UGS to use it.

	#jira none

Change 4008287 by Ben.Marsh

	UBT: Change the engine to use the Windows 10 SDK by default.

	Also add support for switching between specific Windows SDK versions. The WindowsPlatform.WindowsSdkVersion property in the target rules can be used to select a desired version, which can also be configured by the <WindowsPlatform><WindowsSdkVersion>Foo</WindowsSdkVersion></WindowsPlatform> parameter in the BuildConfiguration.xml file.

	The version of Windows to target (ie. the WINVER macro) can be modified by setting WindowsPlatform.TargetWindowsVersion. The default is 0x0601 (Windows 7).

Change 4008516 by Chad.Garyet

	- Adding support for both SQLite and MsSql
	- API now reads from only MsSql, but writes to both
	- Added support for POST to CIS for badges
	- PostBadgeStatus now writes out via API Url rather than a direct connection to the DB

	#jira none

Change 4010296 by Chad.Garyet

	Moving SQLite db initilization into Application_Start.  An exception thrown creating or seeding the db will unload the entire AppDomain and all pages will return a 404.
	#jira none

Change 4024045 by Ben.Marsh

	Set the list of supported target platforms for OnlineSubsystemGameCircle.

	#jira UE-57887

Change 4031014 by Ben.Marsh

	UAT: Add a WhitelistDirectories list in DefaultEngine.ini, which allows specifying folders that can be staged despite having restricted folder names.

============================
  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

	Unhide the text asset format experimental editor option

Change 3807746 by Josh.Engebretson

	Remove WER from iOS platform

Change 3807928 by Robert.Manuszewski

	When async loading, GC Clusters will be created after packages have been processed to avoid situations where some of the objects that are being added to a cluster haven't been fully loaded yet

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"
	 - Add -outputFormat option which can be assigned "text" or "binary"
	 - When saving binary, use a differentiated filename so that source assets aren't overwritten

Change 3809518 by Ben.Marsh

	Remove the outdated UnrealSync automation script.

Change 3809643 by Steve.Robb

	GitHub #4277 : fix bug; FMath::FormatIntToHumanReadable 3rd comma and negative value

	#jira UE-53037

Change 3809862 by Steve.Robb

	GitHub #3342 : [FRotator.h] Fix to DecompressAxisFromByte to be more efficient and reflect its intent accurately

	#jira UE-42593

Change 3811190 by Graeme.Thornton

	Add support for writing specific log channels to their own files

Change 3811197 by Graeme.Thornton

	Minor updates to output formatting and timing for the text asset commandlet

Change 3811257 by Robert.Manuszewski

	Cluster creation will now be time-sliced

Change 3811565 by Steve.Robb

	Define out non-monolithic module functions.

Change 3812561 by Steve.Robb

	GitHub #3886 : Enable Brace-Initialization for Declaring Variables

	Incorrect semi-colon search removed after discussion with author.
	Test added.

	#jira UE-48242

Change 3812864 by Steve.Robb

	Removal of some unproven code which was supposed to fix hot reloading BP class functions in plugins.

	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

	#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.


Change 3778954 by Nick.Darnell

	Slate - Making the Horizontal and Vertical analog keys configurable in the navigation config.  Tweaking how fast the navigation is with the analog stick, trying to tune the feeling.


Change 3778896 by Ben.Marsh

	Separate FNameEntrySerialized from FNameEntry, rather than deriving from it. It has to be allocated differently, and many fields cannot be shared between the two.

	#jira

Change 3778807 by Ben.Marsh

	Fix Tencent include paths not registering if workspace directory contains a space.

	Tencent include paths currently have a trailing backslash, and this is surrounded by quotes if the root directory contains a space. The backslash is interpreted as escaping the trailing double quote.

	#jira

Change 3778686 by Luke.Thatcher

	 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.

	#jira FORT-61390

Change 3778679 by Thomas.Sarkanen

	Fix Linux server crash - dont attempt to run threaded work in a single-threaded environment

	We dont attempt to run animation update work multi-threaded in the same conditions that we didnt attempt to run animation eval work previously.

	#jira FORT-61548

Change 3778591 by Ben.Woodhouse

	Add build config to FPSChart HTML output

	#jira FORT-56478

Change 3778175 by ben.marsh

	Remove code to trigger an ensure on Arxan guards. We already send analytics for this, and don't need this legacy path. There is a large number of incoming ensures with this callstack that are clogging up crash reporter.

	Will remove all the surrounding code in a later update to a development branch.

	#jira

Change 3777750 by Chris.Gagnon

	- Slate now supports a CustomBoundary Navigation type wich allows a custom handler if the boundary is hit.
	  - This provides the ability to have normal navigation while within the boundary and the custom function only on the boundary.
	  - This differs from Custom which is a full override of the navigation behavior.

	 [XBOXONE] [~] Remove stall in D3D12 CreateRHIBuffer
	 - Buffer update is enqueued as a task on the RHI thread instead of stalling the RHI thread for the duration of the update.


Change 3775488 by Thomas.Sarkanen

	Prevented skeletal meshes that are not being ticked due to URO from dispatching tick tasks

	#jira FORT-61157 - Run anim update on worker, even if not visible

Change 3775219 by Bob.Tellez

	#UE4 Dont SerializeThumbnails when calling savepackage while editoronly data is excluded (cooking). This saves a lot of memory while cooking

	UE4 - Fixed rare crash caused by unmounting pak files.


Change 3773920 by Gil.Gribb

	UE4 - Added experimental option r.StartPrepassParallelTranslatesImmediately which allows the parallel translate tasks from the prepass to start before we init shadows. Disabled by default.


Change 3773896 by Thomas.Sarkanen

	Now when meshes are set to EMeshComponentUpdateFlag::AlwaysTickPose, we optionally kick of a task to perform parallel update only (no evaluation).

	#jira FORT-61157 - Run anim update on worker, even if not visible


Change 3773886 by Gil.Gribb

	UE4 - Reduced r.RHICmdMinCmdlistForParallelSubmit from 2 to 1.

Change 3773011 by Robert.Manuszewski

	Header (uasset) and export (uexp) files will now be compared seperately when running cook commandlet with -diffonly to avoid situations where a mismatch in size of the header produces more differences between exports.

	+ Renamed ini setting to ignore header differences from SkipHeaderDiff to IgnoreHeaderDiff


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"

	#jira FORT-52823 - Nativizing Player Animation Blueprints

Change 3772408 by Robert.Manuszewski

	Cook commandlet will now report full property name when running a diff against the existing cook (-diffonly)


Change 3772359 by Thomas.Sarkanen

	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.

	#jira FORT-52823 - Nativizing Player Animation Blueprints

Change 3771975 by Zak.Middleton

	Fix character proxies doing up to two floor check when only rotation changes. Add some optional verbose logging to FindFloor() and ComputeFloorDist().

	#jira FORT-61134

Change 3771421 by Ori.Cohen

	Fix CIS


Change 3771052 by Robert.Manuszewski

	Package diff improvements (-diffonly mode for cooker). Exposed max diffs to report to ini and added the ability to suppress header differences reporting as they are usually a result of differences in exports anyway.


Change 3771039 by Bob.Tellez

	#UE4 Allowing use of -FPS in PGO profile builds


Change 3770747 by Ori.Cohen

	Added missing stat named events for anim bp


Change 3769616 by Arciel.Rekman

	UBT: Use response files for compiler when compiling for Linux.

	- Some command lines are too long when cross-compiling on Windows, which is a problem for non-unity builds (or local changes that result in exclusion of checked out files from the lumped units).

Change 3769457 by Gil.Gribb

	UE4 - Added eviction to r.DoLazyStaticMeshUpdate. It just removes 10 prims a frame in a rolling fashion.


Change 3769136 by Michael.Noland

	Engine: Improve IsServerDelegateForOSS to allow it to use the play world during PIE even if no context was passed in


Change 3768736 by Robert.Manuszewski

	More debug info for ensure in FLinkerSave when a name that has not yet been mapped is being serialized

	#jira FORT-60943

	Duplicating CL 3764661 from Paragon:

	Only update Children attached to Sockets in USkeletalMeshComponent::PostBlendPhysics().
	Saves ~20% of STAT_UpdateChildTransforms and ~10% of STAT_UpdateLocalToWorldAndOverlaps in 5ofEach_Dusk_vs_Dusk automation test.

	#jira OR-46341

	#tests LaneMinionFXTests, monolith w/ full teams.

Change 3768504 by Thomas.Sarkanen

	Duplicating CL 3758315  from Paragon:

	Optimized PostAnimEvaluation when URO is skipping a frame with no interpolation. Skip unnecessary work.
	PreEvaluateAnimation() is now only called if we're about to evaluate anims. PostEvaluateAnimation() is also called only if we have evaluated animations.
	Therefore PostEvaluateAnimation() has been pulled inside of PostAnimEvaluation() instead of FinalizeTransforms.
	Added a call to ConditionallyDispatchQueuedAnimEvents() in the event that we're not calling PostBlendPhysics because we have not evaluated or interpolated anims.
	Added missing call to PostEvaluateAnimation() for PostProcessAnimInstance.

	#jira OR-46341

	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!

Change 3755896 by Arciel.Rekman

	Remove unnecessary switch for profiling (part of FORT-58878).

	- -fno-omit-stack-pointer is only needed when getting callstacks for perf.

	#jira FORT-58878

Change 3755711 by Mike.Fricker

	Fix "double-delete" crash when using level streaming
	- Initialize network GuidCache entries as soon as Guids are registered on the server so that we can fill them out with valid information before the object is destroyed. Fixes issues when a guid is exported for the first time to send a destroy to clients. (from RyanG)


Change 3755701 by David.Ratti

	FObjectReplicator no longer a GCObject since adding/removing from the global GCObject list is too slow. Managing FObjectReplciators's object references at the NetDriver level now.

	#review-3755702 @Ryan.Gerleve

Change 3754928 by Arciel.Rekman

	Linux: add LTO support and more.

	- Adds ability to use link-time opitimization (reusing current target property bAllowLTCG).
	- Supports using llvm-ar and lld instead of ar/ranlib and ld.
	- More build information printed (and in a better organized way).
	- Native scripts updated to install packages with the appropriate tools on supported systems
	- AutoSDKs updated to require a new toolchain (already checked in).
	- Required disabling OpenAL due to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219089

	#jira FORT-58878

Change 3753986 by Ben.Zeigler

	#jira UE-45505 Fix issue where FCoreUObjectDelegates::OnAssetLoaded was being called from an inner loop inside EndLoad. Maps would register components from that callback, and if those registers started their own loads, those objects would be returned in a partially loaded state. We now defer the asset loaded callback to the very end of the loop so recursive loads work properly


Change 3753274 by Ben.Marsh

	Fix blank lines in errors and warnings being omitted from notification emails.

	#jira

Change 3753175 by Thomas.Sarkanen

	Fix hang in animation editor menus

	Sound waves were being loaded by the visibility delegate for the 'play' button overlay. This caused major hangs as the ogg compressed data was built on the fly. Handled the unloaded asset case in the various delegates.
	Also made the menu larger, as picking a sound wave was all but impossible when you couldnt even see one in the list.

	#jira UE-52271 - Persona menu option locks up editor


Change 3752887 by Nick.Darnell

	Slate - Adding automatic invalidation to a few more widgets that were found lacking when adding or removing children.


Change 3752785 by Marc.Audy

	Avoid doing any work to evaluate streaming volumes if there are no player controllers using streaming volumes

Change 3752185 by Ben.Marsh

	Reduce cook time regression caused by correcting package names to match case on disk (to fix deterministic cooking problems). Switched to use IPlatformFile::GetFilenameOnDisk(), and improved performance of FWindowsPlatformFile::GetFilenameOnDisk() by using GetFinalPathNameByHandle() instead of recursively searching up the directory tree.

	#jira

Change 3751813 by Ben.Marsh

	Improve parsing of diagnostics for deterministic cooking test. Now allows multiple lines in the generic EC error/warning matcher if indented more than the first line, and skips over empty lines.

	#jira

Change 3750413 by Ben.Zeigler

	Fixes for cook save performance regressions. Add GetAllMarks to object and use that to dramatically reduce contention for the object mark annotation. Implement ShouldLoadForServer/Client directly on some core classes to stop it from calling the slow generic one
	Fix issue where refreshing tags for asset registry would do a very slow array delete/add
	Improve speed of redirectcollector, there's no need to force-rehash the soft object path list as the remove handles it conditionally


Change 3750014 by Lina.Halper

	- duplicate change from following changelists

	CL 3669273 - delete all tracks option
	- allow to opt out on bone track importing

	Fixed compiling error in Automation project

	#jira FORT-59621

Change 3748530 by Mike.Fricker

	Fixed non-determinism of landscape grass across platforms/compilers

	This causes bushes to be located in different places depending on what platform you were playing on.

	1)  Random number reseeds were happening as part of function arguments to FVector(), but function argument evaluation order is unspecified, and behaved differently on Consoles/Mac/Windows.  Fixed this bug.

	2)  Strings used for foliage CRCs could use different character sizes on different platforms.  Now we always use ANSI.

	3)  Strings used for CRCs could have possibly have different case.  Now forced lowercase.

	#jira FORT-60109

Change 3748471 by Zak.Middleton

	Added stats to NetDriver TickFlush and stats gathering within that function.


Change 3748287 by Brian.Bekich

	Deprecating MAX_STRING_SERIALIZE_SIZE in favor of the cvar
	FInBunch defaults to prior behavior if cvar is 0
	UPackageMap::SerializeName and UPackageMapClient::SerializeNameAsString will always cap at NAME_SIZE
	Check for path name serialization error before tryng to read checksum

	UE4 - Fixed XBox and Windows thread priorities. Only 2 though -2 seem usable and some of the old values were being ignored.


Change 3747548 by Gil.Gribb

	UE4 - Changed thread pool to be TPri_SlightlyBelowNormal so that they will not preempt HP task graph tasks.


Change 3747544 by Bart.Hawthorne

	When detecting if Oodle is installed, use the newest version instad of the oldest one.


Change 3746440 by Robert.Manuszewski

	Dterministic cook issues reporting improvements

	- Huge performance improvements
	- Added new metric to the summary: NumberOfDifferencesInPackages
	- Diff stats have their own section now (Package.Diff)
	- When running with -diffonly there commandlet will not log the Warning/Error summary anymore
	- Callstacks are no longer logged with instruction addresses
	- Because callstacks are no longer logged with addresses I can collapse them for structures that otherwise would be split into multiple separate callstacks
	- Callstacks, Serialized Object and Serialized Property are now indented
	- Each asset is capped at 5 entries. If there's more differences, they'll be logged as single warning.
	- Replaced \r\n with \n in the callstack log to make it work better with EC

	#jira FORT-59919


Change 3746426 by Gil.Gribb

	UE4 - Tuned dispatch in the deferred renderer. Added r.DoPrepareDistanceFieldSceneAfterRHIFlush and defaulted it to on.


Change 3746348 by Mike.Fricker

	Added new CVars to toggle level streaming behavior
	- No effective change to engine yet.  The defaults values enable the same default behavior.
	- New CVar:  "s.ForceGCAfterLevelStreamedOut"   (Whether to force a GC after levels are streamed out to instantly reclaim the memory at the expensive of a hitch.)
	- New CVar:  "s.ContinuouslyIncrementalGCWhileLevelsPendingPurge"  (Whether to repeatedly kick off incremental GC when there are levels still waiting to be purged.)
	- New CVar:  "s.AllowLevelRequestsWhileAsyncLoadingInMatch"  (Enables level streaming requests while async loading (of anything) while the match is already in progress and no loading screen is up)


Change 3746127 by Gil.Gribb

	UE4 - Slight tweak to more agressively batch occlusion queries.

Change 3745631 by Matt.Kuhlenschmidt

	Fix details panel crash after compiling blueprints that have edit conditon properties


Change 3744544 by Gil.Gribb

	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.

	#jira FORT-59879

	#UE4 - fix for crash in destructor probably related to the freeing of memory via default destructors AFTER CefShutdown() has been called

	#tests crashes before, no crash after (not sure if it was a 100% crash but this seems better regardless)

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.


Change 3742053 by Michael.Trepka

	Copy of CL 3713881

	Added -buildscw to Mac Build.sh script to build ShaderCompileWorker in addition to the requested target. Xcode passes it to the script when building non-program targets.

	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.

	Updated FMallocLeakDetectionProxy to not use a critical section internally on top of thread safety measures performed by FMallocLeakDetection and the underlying FMalloc implementation. The improvements are biggest on Mac, in particular in low framerate situations, as Metal RHI uses malloc heavily on multiple threads, but it's also a nice 10% improvement on a high end PC.

	- add DECLARE_GPU_STAT macro which handles STATS and CsvProfiler declarations

	Note: still a few issues to resolve with GPU stats: these randomly go to 0 at times during a replay on XB1, the GPU total is lower than the stat unit number, and the unaccounted stat is too large due to missing stats

	Engine Code Improvements (that this project doesn't have yet);

	Added engine code for drawing a debug 2D box.
	Added engine code that allows for Keyboard Shortcuts to be special characters like backslash \.

Change 3701976 by Michael.Noland

	Editor: Rewrote CallInEditor support and promoted it so it can be used on functions in any class, not just blueprints derived from AActor:
	- CallInEditor used on native UFUNCTION() declarations will now show up without having to make a BP subclass
	- 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...)

	Editor: Moved Experimental/EarlyAccessPreview details customizations up to UObject so it can be used on any class, not just actors/components

	Edigrating CL# 3374995, 3375121, and 3375308 from Dev-Framework to FN main

	Modified commandline parse function, to detect when it is incorrectly parsing a parameter, from within another parameters value (not exhaustive).

	For example, this commandline only contains the parameter ParamA. It should not be possible to parse ParamB, as it is part of ParamA's value:
	-ParamA="-ParamB=Value"

	Speculative fix #2 for a server crash/assert. If the timing is right, it's possible for the server to try to re-load a placed-in-map actor that was previously garbage collected.

	 [~] 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.

	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).

	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.

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

Change 3658809 by Chris.Bunner

	Changing default HDR display gamut to P3 as in practice that's more common than Rec2020, this should be a user-facing option where possible though as we can't automatically retrieve that data.

Change 3658842 by Chris.Bunner

	Backing out previous HDR default gamut change as it conflicts with mandatory platform defaults.

Change 3695269 by Arne.Schober

	DR - vk - Fix validation issue

Change 3697488 by Richard.Wallis

	Fix for Mac editor session no longer accurately tracking Mouse location after moving between Desktops in Mission Control on 10.12.6.  Problem stems from the extra call to update the slate cached window position in mouse move while dragging, which is itself is a hack but apparently this is needed as we don't get window position updates on Mac while dragging (although I couldn't see any -ve side effects without it) then the OS (in 10.12.6) doesn't always push out a final window did move notificaiton when changing desktops which leaves the window according to slate incorrectly positoned to it's frame.

	Solution is to either remove the mouse-move-while-drag window position hack or add a final window position update to the mouse-up event while dragging - this change is the latter.

	#jira UE-37553

Change 3697501 by Richard.Wallis

	Move audio processing over to audio bus tap.  Currently on Mac Media audio playback uses OS media player mixer rather than Engine as existing implemtation, using AVAssetReader, now suffers from poor performance with new Media Framework.  This audio tap version replaces that asset reader implementation but also suffers from bad quality audio hence is still disabled at the top of AvfMediaTracks.cpp.

	Original Code Review Description:

	Convert Mac to Play audio through the engine MediaFramework API rather than using AVMediaPlayer.  This is the Mac implementation only - this should work ok on iOS but unable to test due to missing audio type implementation (throws error "Init Buffer on unsupported sound type name = Synth type = 5"), as such is only enabled for Mac.  There maybe some extra tweaks required for iOS on app backgrounding etc if this feature is enabled.

	- Stuttering Audio Performace issue investiagation:  Re-Tested this implementation against [now fixed] current Mac implementation which was working fine last year and that implementation now has the same audio output quality (performance) issues as this one.  Basic investigation seems to point to somewhere in the engine audio handing.  When poor audio is heard the FMediaAudioResampler::Generate() function is dequeing an IMediaAudioSample sample buffer and the audio sample queue usually has 50-100 of these IMediaAudioSample buffers waiting in the queue.  I think the AvfMedia playback system is providing the sample buffers in good time but they are not getting consumed "fast" enough.  This under consuming also occurs if I force the Core Audio - Audio Unit mixer to use 48000 samples/sec.

	#jira UEPLAT-1677

Change 3697517 by Richard.Wallis

	XCode 9.0 extra nullability specifiers required.

Change 3697537 by Richard.Wallis

	Back out revision 23 from //UE4/Dev-Rendering/Engine/Plugins/Media/AvfMedia/Source/AvfMedia/Private/Player/AvfMediaTracks.cpp

Change 3697670 by Rolando.Caloca

Change 3699959 by Rolando.Caloca

	DR - Fix barrier in the middle of render pass

Change 3699969 by Rolando.Caloca

	DR - vk - Change dump layer location so it prints out validation ids

Change 3700356 by Guillaume.Abadie

	Implements secondary screen percentage to be able to do TAA upsample followed spatial upscale so that the editor viewport still have same TAA upsample screen percentage range to test the content with no matter monitor's DPI.

Change 3701105 by Guillaume.Abadie

	Ignore per view automatic mip bias on texture type other than 2d textures.

	#jira UE-51396

Change 3702297 by Richard.Wallis

	Mac compile fix for nullable specifier.  Looks like Obj class using the C++ class also needs this otherwise it throws.  Seems to be some kind of xcode/compiler caching bug with this stuff as it'll report the error once then on subsequent compiles say everything is ok.

	#jira UE-51386

Change 3702357 by Richard.Wallis

	Mac nullability compile fix - again.  Looks like I fell foul of that xcode compile caching!
	#jira UE-51386

	#jira UE-51395

Change 3702464 by Guillaume.Abadie

	Fixes wrong viewport to buffer conversion of the distortion.

	#jira UE-51406

Change 3704730 by Rolando.Caloca

	DR - vk - Fix map for depth surfaces

Change 3704739 by Rolando.Caloca

	DR - Debug label on D3D11 UAVs
	- Validate when running -d3debug

Change 3705000 by Chris.Bunner

	Skip compiling opacity and opacity mask inputs on opaque surface materials. Previously the code was always added to the shader, sometimes we force opaque materials down a masked path which then calls the dormant code unintentionally. A safer fix for UE-48254.
	Partially reverted previous fix in CL 3608303 which removed a material instance optimization caching the overridden base properties.

Change 3706065 by Guillaume.Abadie

	Does some renaming for primary screen percentage, and move the primary screen percentage method selection from dynamic resolution driver to FSceneView.

Change 3706464 by Chris.Bunner

	Fixed material property translate overrides that were generating code in the wrong entry.
	Fixed conditions  in If material expression GetInputType and IsMA check.

	#jira UE-51368

Change 3706641 by Chris.Bunner

	Missing "break" in switch statement (which unfortunately needs another bump to resolve).

Change 3706642 by Guillaume.Abadie

	Fixes assertion failure when r.TemporalAA.EnableUpscale = 1

Change 3706650 by Gil.Gribb

	UE4 - UE4 - Changes from intel. Increase number of worker threads on Windows to if hyperthreads (hyperthreads √ 2) else cores √ 1 up to a max of 22 workers. Increase MAX_THREADS multiplier per bank from 22 to 26. Intel VTune ITT event annotations. Wrapped in same function as your existing CPU events and enabled with √vtune. Optimize NV cloth by consuming FVector instead of FVector4 out of the solver. Vertex buffers were using FVector all along. ~15% improvement. Optimize cloth copy to vertex buffer by adding prefetch (similar to how bones are already done). Move local to world cloth transform from CPU to GPU. When simulating lots of vertices game thread was becoming bottleneck doing matrix multiply. Add your TaskGraph task switch latency test code.

Change 3706733 by Daniel.Wright

	Print Embree Build time

Change 3706841 by Daniel.Wright

	EmbreeFilterFunc4 now handles masked out intersections properly

Change 3709633 by Rolando.Caloca

	DR - vk - Compile fix

Change 3710454 by Mark.Satterthwaite

	Refactor the way we compile Buffer<> & RWBuffer<> types for Metal so that we can support the type-conversion semantics of HLSL/D3D.
	- Buffer<> types are converted to Linear Textures unless the internal type is 3-compnent or the STRONG_TYPE macro is added as a type-qualifier. Linear Textures require an MTLTexture "view" object be created around the MTLBuffer which is the backing-store and it is typically best if that buffer is marked as Private (GPU-only) memory, reading from this in the shader then uses the texture-fetch hardware to perform the format conversion on load.
	- RWBuffer<> & 3-compnent Buffer<> types are converted to use template functions to load/store - the implementation of which will read the format from the BufferSizes meta-table and determine which type-conversion to apply. Function-constants are used to specialise the shader where feasible to reduce branch costs (function-constants are a Metal feature that allow efficient runtime recompilation of bytecode shaders).
	- Buffer<> & RWBuffer<> types where the STRONG_TYPE macro is added as a type-qualifier (only does something on Metal, everywhere else it is #define'd away) are compiled as "raw" Metal buffers of the inner-type (e.g. float4 for Buffer<float4>) and the MetalRHI runtime will enforce that only SRVs/UAVs of the proper format are bound to it. This is necessary in a couple of cases (BoneMatrices, NumCulledLightsGrid, CulledLightDataGrid & ForwardLocalLightBuffer buffers) which are used in a larger number of shaders as Linear Textures have poorer performance than Buffer<>/RWBuffer<>.
	- Most of the complications to generating subtly different Metal code for different OS/device combinations have been factored out into ue4_stdlib.metal which acts as an extension to the Metal shader standard-library and helps simplify the MetalBackend code - particularly helpful for Buffer<>/RWBuffer<> but also texturecube_array and the SM6 wave-related intrinsics.
	- Reverted some of the awkward Metal-specific changes Richard.Wallis & Arne had to make to the high-level shaders as they aren't necessary anymore.
	- Made the existing Metal-specific changes to use uint32 for all light-grid injection buffers apply to all Metal platforms again (I had hoped that it would not be necessary anymore, but it is much faster this way).
	- STRONG_TYPE is actually hlslcc's "invariant" keyword applied as a type-qualifier to a Buffer<>/RWBuffer<> type - only valid when using Metal which exports this through ILanguageSpec and #define'd out for everyone else.
	- Old versions of iOS (anything earlier than iOS 10.3) won't be able to use this new code, so every buffer will be treated as "raw" and the MetalRHI will now properly report when something goes awry rather than it leading to mysterious rendering errors and crashes.

Change 3710456 by Mark.Satterthwaite

	Fix the Eddie workset project generator so that Enterprise projects don't get mixed in with regular projects at the top-level because of the way Eddie combines workset groups.

Change 3710457 by Mark.Satterthwaite

	DX11 texture formats for Mac Metal please!

Change 3710480 by Mark.Satterthwaite

	Permit RHI thread and parallel execution in Mac -game mode again.

Change 3710522 by Mark.Satterthwaite

	MSVC type-mismatch error fixes.

Change 3710580 by Mark.Satterthwaite

	Alright then - if I can't use the C++11 extended string semantics I'll have to use "xxd -i" to generate a hex-dump include header from ue4_stdlib.metal instead. This can only be updated from a machine with access to the POSIX xxd command (Mac & Linux, possibly the new Linux sub-system for Win10).

Change 3710616 by Mark.Satterthwaite

	Missing file.

Change 3712972 by Guillaume.Abadie

	Fixes Circle DOF's negative alpha channel getting clamped to 0 in TAA pass.

Change 3712979 by Guillaume.Abadie

	Fixes wrong RT reallocation when doing TAA upsample in editor viewports with secondary upscale.

Change 3713406 by Mark.Satterthwaite

	Use GPU morph targets on Mac - the necessary buffer conversions will always be available there. For iOS it can only be supported if iOS 10 is the minimum OS & Metal standard so leave that on the CPU path for now.

Change 3713494 by Richard.Wallis

	Fix for hitch when PIE unloading sublevel.  PerformReachabilityAnalysisOnObjects is spawing multiple threads in Editor builds as there is an extra code path that results in Critical Section locking within a singleton type static object - this is a bottle neck for multiple threads.  However they all just need to read the data not change it.  Replaced FScopeLock with a Read/Write version allowing these threads to all take a read lock at the same time to reduce contention.

	Changed the FUObjectAnnotationDense implementation only - left the sparse implementation alone as its not currently affecting this - although we could proactivly change that too.

	Also tested again repro in linked bug UE-24711.

	#jira UE-40533

Change 3713612 by Mark.Satterthwaite

	Integrate LPV_STORE_INDEX_IN_HEAD_BUFFER related changes from //depot/Partners/Microsoft/UE4-MS/Engine-Fable @ 2954744

	This should make Light Propagation Volumes potentially viable on non-Microsoft platforms.

Change 3713623 by Mark.Satterthwaite

	Implement ByteAddressBuffer/RWByteAddressBuffer in hlslcc in a similar manner to StructuredBuffer/RWStructuredBuffer so that the backends don't need too much modification. Implement the necessary changes into MetalBackend to make this work for Metal.

	Load/Store{+2,3,4} & Atomics are supported. Counter operations are not supported and aren't likely to be.

Change 3713636 by Mark.Satterthwaite

	Enable LPVs for Mac Metal.
	- Rework some multi-dimensional arrays & array-index dependent HLSL code that hlslcc simply can't cope with, the mesa-glsl compiler core is only capable of dealing with 1 dimensional arrays and array-indexing can't itself be directly dependent on the result of an array-index operation.
	- MetalRHI needs to ignore any SetRenderTargets call that binds nothing at all as you must bind at least one target (UAV, RT, Depth/Stencil) for it to be able to do anything sensible.
	- Turn on LPVs for Metal as it works now.

Change 3714049 by Guillaume.Abadie

	Do not set screen percentage method to TAA upsample when anti aliasing method is not TAA even if there is automatic fallback in the renderer.

Change 3714306 by Guillaume.Abadie

	Fixes assertion failure in dynamic resolution state proxy with GPU busy time queries.

Change 3714714 by Mark.Satterthwaite

	Tweak Metal GPU identification so that it works with eGPU boxes and protoype hardware - these changes only apply to macOS 10.13 so the system as a whole remains.

Change 3716104 by Mark.Satterthwaite

	Fix 10.12/Xcode 8 compile errors from the build-farm which is still split until Fortnite can update.

Change 3716120 by Mark.Satterthwaite

	Silence static-analysis.

Change 3716158 by Guillaume.Abadie

	Rewrites editor primitive compositing to support TAA upsample.

	This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.

Change 3716271 by Daniel.Wright

	Lightmass correctness fixes
	* After these changes, point, spot, directional and sky lights closely match reference renderer Mitsuba after light unit conversions
	* Photon density trimming intended for direct photons was affecting indirect photons as well.  This caused high noise for point / spot lights with a large attenuation radius.  Indirect photon density even for small lights is 5x with this change, which improves 2nd bounce quality.
	* Removed legacy fudge factor on point / spot light photon energy
	* Spotlights no longer emit based on indirect photon paths.  Fixes excessive photon energy from spot lights as they were emitting outside of the cone.
	* Fixed photons computing one more bounce than requested.
	* Added an option to use the Radiosity solver for all multibounce, replacing photons.  Useful as a reference but generally too much noise indoors.
	* Fixed visualization of photons without final gather

Change 3716434 by Mark.Satterthwaite

	Backout the remaining change from 3632041 that is no longer necessary - this was the last of the 4.18 Metal workarounds.

Change 3716491 by Chris.Bunner

	Fixing up an edge-case on a recent optimization.

Change 3716611 by Guillaume.Abadie

	Allows secondary screen percentage >= 100%.

Change 3716977 by Guillaume.Abadie

	Back out changelist 3716158 to unblock QA pass.

	#jira UE-51580

Change 3717111 by Arne.Schober

	Fixing nomalization of Morph Tangents https://udn.unrealengine.com/questions/392462/
	Also implemanted batching of the dispatches which should help worst case perfomance where dispatches become too small.
	CalculateInverseAccumulatedWeights is not cheap and proably should be moved onto a task thread that runs as soon as the input weights are ready.

Change 3717127 by Mark.Satterthwaite

	Fix a mismerge from the reversion of 3632041 - part of the modified code had been moved into another file and I didn't initially notice.

Change 3717178 by Mark.Satterthwaite

	Remove useless copy-pasted expressions from glsl_type::GetByteAddressBufferInstance & force MetalBackend to relink. Apparently the previous Mac libs were mysteriously broken.

	#jira UE-51583

Change 3717476 by Marcus.Wassmer

	Also enabled the new atomics method for LPVs for all platforms

Change 3718054 by Guillaume.Abadie

	Removes unecessary check() failure on secondary upscale that fires when testing raw output screen percentage method.

Change 3718066 by Guillaume.Abadie

	Reland: Rewrites editor primitive compositing to support TAA upsample.

	This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.

Change 3718589 by Mark.Satterthwaite

	Console-variable to enable and disable Manual-Vertex-Fetch for Metal and fix the internal code to handle the subtle changes in behaviour for vertex-declarations so we don't explode under the Metal validation layer. MVF works on macOS, though testing did expose an error with Tessellation on Nvidia (true for MVF enabled & disabled).

Change 3718633 by Guillaume.Abadie

	Fixes temporal instability issue of TAA upsample with secondary screen percentage.

Change 3718658 by Arne.Schober

	DR - 25% MorphTarget Speed increase because there was a bit of cache thrashing between the waves going on.

Change 3718818 by Mark.Satterthwaite

	Fix compilation on hlslcc - integral values are not automatically converted into comparisons with zero.

Change 3719004 by Guillaume.Abadie

	Lets the game viewport client automatically set raw output screen percentage method when doing dynamic resolution with stereo rendering but without TAA upsample.

Change 3719375 by Mark.Satterthwaite

	Extend mtlpp compiler testing app to support Metal tessellation compute shaders so we can send Nvidia a much simpler reproduction of their regression.

Change 3720099 by Mark.Satterthwaite

	Make the left-hand arguments work in airdiff.

Change 3720413 by Mark.Satterthwaite

	Support standalone compute shaders in the mtlpp compiler test app.

Change 3721232 by Mark.Satterthwaite

	No more Metal Shader Model 4 - instead we have to have a Metal Shader Model 5 w/o Tessellation as Nvidia's shader compiler is broken on all tessellation shaders in 10.13.0 and above. There is no guarantee that they will fix this prior to 10.14 and I can't afford to disable tessellation entirely as if I do that then the AMD & Intel compilers will also regress. As there is no Shader Model 4 platform on Mac anymore I've amended the LevelEditorActions to disable the preview modes when no appropriate shader platform is available.

Change 3722766 by Rolando.Caloca

	DR - Fix static analysis

Change 3722943 by Mark.Satterthwaite

	Disable the METAL_SM5_NOTESS shader platform again - I can workaround the Nvidia pipeline state compiler crash by changing the buffer address space from "constant" to "device" as we're managing to confuse the poor thing. This won't materially affect AMD or Intel as they don't care much about this, but to limit performance issues on Nvidia we only need to do this for Tessellation Compute shaders.

Change 3723100 by Mark.Satterthwaite

	Apparently users like enabling Metal shader standards that won't work on their current OS, so don't display those that aren't going to work & display an error message before quitting rather than crashing when trying to load a project that tries to use an incompatible shader version.

Change 3723121 by Mark.Satterthwaite

	Fix build error.

Change 3723245 by Daniel.Wright

	Ensure for when a reflection capture upload fails due to incorrect lighting scenario level handling
	Reflection captures with no data use an array index of 0, instead of -1.  Might avoid reading uninitialized memory on PS4.

	Render thread dynamic resolution & TAA upsample.

	Merging //Tasks/UE4/Dev-DynamicRes/...@3694528 to //UE4/Dev-Rendering/...

	New features breakdown:
	- TAA upsample compute shader that accepts screen percentage from 50% to 200%, with a faster shader permutation for consoles;
	- Material no longer have to deal with BufferUV, and post process material after TAA upsample can sample any scene buffer seamlessly;
	- Material texture per view mip bias to produce sharper images with TAA upsample;
	- Render thread dynamic resolution heuristic is fully plugable by game code (for VR plugin specific heuristics);
	- Dynamic resolution in PIE and game builds;
	- Busy time queries in the RHI to be implemented on the different platforms so that the dynamic resolution heuristic can  exactly associate GPU frame times with screen percentages in its history;
	- Game user settings to enable/disable dynamic resolution;
	- In editor viewport screen percentage config to previsualise and test content at different screen percentage.

	Fixes:
	- Various fixes for algorithms producing different outputs at different screen percentage.
	- Various fixes for algorithms sampling outside view rects.

	Refactors:
	- TAA shader
	- Moved some screen percentage specific members from FSceneView to FViewInfo for thread race bullet proofing.

	Aknowledgements:
	- VR plugins are broken
	- DFAO still have some artifacts

	Premiliminary review: Marcus.Wassmer
	Review for TAA refactor and TAA upsample shader: Brian.Karis
	Review for dynamic resolution: Brian.Karis

Change 3582039 by Matt.Kuhlenschmidt

	High DPI mode changes

	#jira UE-46573

Change 3590435 by Jamie.Dale

	Added support for in-editor previews of localized game text

	This is configured by the "Preview Game Culture" setting, and will automatically be active when PIE is running (the preview language is also passed to any standalone games that are launched via the editor). This preview can also be used in the UMG editor to preview widgets in different languages.

	While a preview is running, all editable FText fields are locked-down (read-only) to prevent accidentally clobbering source data with translation data. You can also use this new lock-down feature to prevent any localization changes in your project (set "LockLocalization" to "True" under the "Internationalization" section of either your DefaultGame or DefaultEngine INI).

	In order to allow the game translations to be used in the editor, we now map the translation to any package localization ID variants when the LocRes data is loaded (or when looking up a specific piece of text). This is needed as the LocRes files only ever contain the "clean" versions of the IDs (without the package localization ID the editor uses), and also means that we no longer need to gather the "editor-only" variants of the text within assets.

	#jira UE-47464

Change 3592200 by Matt.Kuhlenschmidt

	Fix drag drop of actors being offset with high dpi monitors.

Change 3592719 by Bradut.Palas

	#jira UE-45632 - dual key bindings feature

	My approach was transforming the ActiveChord and DefaultChord into arrays and accessing them through an enum class called EMultipleKeyBindingIndex. A lot of connecting code, function prototypes, and data structures had to be changed to accomodate this. Most menus and tooltip texts are generated using the first valid active shortcut.

Change 3592793 by Bradut.Palas

	#jira UE-48167 profiler crash

	Don't duplicate the graph data when rebuilding because that completely voids the OneToOneMapping mechanism, resulting in the crash. Looking up objects in the mapping would always return null because the mapping contains the old addresses, before the rebuild.

	One option would have been to completely rebuild the mapping according to the duplicate graph, which would be dubious because the duplicate method isn't specifically designed so that the result would replace the source.

	But it looks like duplicating the data is not needed, it's safe to rebuild in-place, RebuildForFilter() doesn't do anything illegal with the objects. This is also the only purpose and the only reference of the function.
