	- Moved large map of hlsl keyword replacements from C++ to ini file to improve compile times.
	- Now not using templates to handle input parameters to data interface. Now taking a bit from the bytecode offset to denote constant vs register.
	- As well as improving compile times, this also makes DIs far easier to write and maintain so I've rolled out to all DIs. Has no affect on perf.
	- Moved some things into the VectorVM namesspace.

Change 4415679 by Rolando.Caloca

	UE4.21 - Copy fix from 4415584 and 4401641
	- Added support for -vulkanpresentmode=N where N is a VkPresentModeKHR
	- This prevents the CPU from getting more than one frame ahead of the GPU. In addition to making the Vulkan RHI more consistent with the DX RHIs and reducing game input latency, this also fixes the issue where memory for volatile uniform buffers could be overwritten by the CPU before the GPU was done with it. This could happen when running in immediate present mode with frame pacing and smoothing disabled, as the CPU could get several frames ahead of the GPU.

	    - Changed logic in building of FOverlappingCorners to be based on index of wedge, number of wedges equal 3 times the number of triangles like in FRawMesh, instead of index of vertex instances.
	   - Updated BuildVertexBuffer to take this new logic in account.
	- Fixed crash in FMeshDescriptionOperations::CreateMikktTangents:
	   - MikkTSpace sdk does not handle properly faces with 0 vertices which occur with mesh description with invalid polygons.

	UE-61351 Error: Failed to send -1 bytes of data to RemoteConnection spammed in the editor log when closing RemoteSession on device during connection

	#jira UE-61351
	#4.21

	Not an real issue. The message is issued whenever the host (or the client) tries to send messages through an inactive channel. There is a "/ping" message sent back and forth between the host and the client, with high frequency (hence the spam) - if this message is no longer received, the host (or the client) decides to terminate the connection.

	"Downgrading" the message from Error to Log, to avoid spamming the log on release builds.

Change 4354338 by Ben.Marsh

	Attempted fix for incorrect certificate errors when compiling remotely.

	* Overloaded meaning of the -Certificate argument (ie. as the output path rather than as the desired certificate when selecting a provision) was causing certificate name check to fail. Now uses a different parameter to specify the output path.
	* TVOS argument was not being passed when exporting the certificate, also causing the wrong provision/certificate pair to be selected.
	* Add support for the -bundlename argument, though it shouldn't be necessary when invoked from UBT since the UUID discovered in a previous invocation of IPP is explicitly specified.

	Since the provision UUID is already being specified to IPP, it should be able to identify the correct provision on phase -1 using this info.

============================
  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 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)

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

	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

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

	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

	#jira UE-60554

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

	UGS: Added support for showing the latest completed build from a specific list of badges in the status panel. To declare a badge as one that should appear in the status panel rather than the CIS column, add it to the project's UnrealGameSync.ini in the project or [Default] section like so:

	+ServiceBadges=RoboMerge

	+Columns=(Name="Mobile",MinWidth=50,DesiredWidth=100,Weight=3,Badges="IOS,Android")

	Same form can be used to control how default columns are displayed (though badge settings are ignored). Also allow PerforceMonitor to detect local changes to project config files and update settings automatically.

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.

	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.

	UBT: Add utility functions to the log class to allow formatting errors and warnings in Visual Studio output format (eg. File(Line): warning: Message)

Change 4230871 by Ben.Marsh

	UAT: Remove StreamUtilis utility class; there is a simpler way to implement the one place it's used.

Change 4230882 by Ben.Marsh

	UAT: Add StreamUtils back into UAT, seems like it's still used there.

Change 4230896 by Ben.Marsh

	UBT: Remove some redundant parameters from UEBuildModule/UEBuildModuleCPP/UEBuildModuleExternal constructors.

Change 4231014 by Ben.Marsh

Change 4234193 by Ben.Marsh

	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):

	RuntimeDependencies.Add("$(OutputDir)/Foo.dll", "$(PluginDir)/Source/ThirdParty/Foo.dll", StagedFileType.NonUFS);

Change 4234872 by Ben.Marsh

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

	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.

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

Change 3795481 by Nick.Shin

	HTML5 - disable SupportsScreenPercentage() - render the full screen

	otherwise, this is causing HTML5 screen to only render a portion of the screen and in black...
	- there may be another function is that not getting fired off "to render the screen" properly
	- this may be due to IsMobileHDR checks that are not fully accounted for the HTML5 platform

	#jira UE-52640  HTML5 only renders a black rectangle in the browser when launched

Change 3807007 by Nick.Shin

	HTML5 - remove webgl1 only precompile guards (UE4_HTML5_TARGET_WEBGL2)

	HTML5 - code cleanup

	origial work was for: UE-27141 (Remove all #if PLATFORM_HTML5 from high level code)

	#Android
	#jira UE-54139

	S8 on 7.0 is not hiding suggestions and disabling predictive input.  There are cases with this that can cause a crash.

Change 3844210 by Nick.Shin

	HTML5 - filter out "windows/super" keys - these are not used in UE4

	- but, keycode are not the expected "91 or 92" values, SDL keys are "227 & 231" instead...

	#jira UE-54056  HTML5 crashes inside browser upon pressing windows key

Change 3844874 by Nick.Shin

	HTML5 - detect "SyntaxError: " and do a forced reload

	- an actual syntax error would be caught during compile time

	UE-49173 Progress bar causes black screen on iOS

	#iOS
	#4.20
	#jira UE-49173

	The bug occurs on iOS with Metal, when the last Slate element to be draw in the scene is a ScrollBar with progress between 0 and 1.
	As a workaround, adding another widget (eg. button, image) in the Blueprint solves the problem.
	The bug can be reproduced by adding OutDrawElements.PushClip & OutDrawElements.PopClip in any SWidget::OnPaint.

	The solution is to disable the scissor
			RHICmdList.SetScissorRect(false, 0, 0, 0, 0);
	in FSlateRHIRenderingPolicy::DrawElements after the batch rendering

	UE-54490 Android Startup Movie audio still playing when app paused, and after app resumed the movie is blackscreen until engine ticked.

	#Android
	#4.20
	#jira UE-54490

	Call ForceCompletion for the intial movie player on onPause.
	Call App Restart on Resume.

	Programmatically restarting an Android application basically consists in killing the current app, then using the launch intent as parameter for startActivity.

	This can be done only in onResume , which means that the movie player still has to be manually paused/stopped in onPause.
	I╞ve tried to kill the activity on onPause, tested on several devices, with various problems: the app doesn╞t restart anymore (onResume is not called) or the app is automatically sent to background (seems to be crashing when using the multitasking soft key).

	Run on device: Pressing Cancel on the "Running..." message should stop the application, if running

	Cancel Android builds using "adb shell am force-stop <bundle_id> <device_id>"

	Note: Using a new AutomationTool command (re-starting the Automation tool after canceling the BuildCookRun task chain) is too slow - takes 3-10 sec depending on the PC configuration.

	AutomationTool is used now only to correctly retrieve the bundle id for each Android device. This is done inside the BuildCookRun command when the application is deployed on the device(s). Cannot simply use the current project's properties to retrieve the bundle id, because when using Launch-> Device Launcher, the user can choose to cook&deploy a different project/texture format, also the user can create & use a profile with multiple devices / with different texture formats.

	UEMOB-436 Support "All Android" Launch On and Project Launcher options

	The main change is in the DeviceProxy class.

	A new type ("All devices" proxy) was added, and the proxy now holds a list of physical device IDs for every variant (texture format), instead of a single device ID.

	The "All devices" proxy is updated automatically by the device discovery thread.

	The change was necessary because the list in the Project Launcher is using the device proxy list.

Prevents problems with cooked versions of games not working properly on Metal due to a mismatch between the runtime's Manual-Vertex-Fetch state versus the state used by the cooker when compiling shaders.

	The previous (4.18) behavior was to only allow selection of the previous/next item in the list with arrow keys. A fix (CL 3783114) for pickers with many assets broke this. This change now allows for selection of any item by navigating with arrow keys and pressing Enter, as suggested in the Jira.

	LLM update: Added Total, Untracked and FMalloc Unused to LLMFULL stat page. Fixed occasionally missing allocs/frees. Removed platform csv.

	* removed CheckSize arg from OnLowLevelFree
	* show a warning in LLM Map when replacing existing value. This means that there has been an alloc/free mismatch.
	* minor optimization in LLMMap::GetMaxIndex - cache Mask value
	* added Total and Untracked stats to LLMFULL. LLMFULL now tracks almost all of the memory that LLMPlatform does, so there is no real need to use LLMPlatform. Removed the LLMPlatform csv.
	* added FMalloc Unused stat to LLMFULL to account for memory Binned2 has allocated internally. This can be used to track Binned2 fragmentation over time.
	* renamed Binned stats to FMemory to make it more general
	* added Default tracking to CustomVirtualAlloc and disable it where necessary. This catches the few VirtualAlloc calls that were missed.
	* added AllocType arg to all allocation tracking. This was needed in order to track the FMalloc total, and also to fix the pausing
	* fixed a bug in pausing where alloc/frees were being missed. Now only pauses a specific allocation type.
	* Trackers now maintain totals for each enum tag

	Merging CL 3659069 from //Fortnite/Main/... to to //ue4/dev-console/...:

	[FORTNITE] [CONSOLE] [+] Improved frame syncing mechanism
	 - Improves input latency by allowing the game thread to sync to the swap chain flip of the previous frame.
	 - Added "r.GTSyncType" CVar to control how the game thread syncs with the rest of the pipe.
	 - r.GTSyncType 2 will sync the game thread with the flip of the swap chain, preventing the pipe from getting too long and causing excess input latency.

	Platforms are required to implement RHIWaitForFlip and RHISignalFlipEvent, and call RHIInitializeFlipTracking on RHI startup.
	A separate thread monitors the progress of frame flips and signals task graph events as they pass their corresponding frame index.
	In r.GTSyncType 2 mode, the game thread is signaled by this flip tracking thread.

	[~] Unified platform specific sync interval CVars into one: rhi.SyncInterval
	 - 1 == 60Hz
	 - 2 == 30Hz
	 - 3 == 20Hz

	 - Replaced explicit use of FPlatformMisc::Begin/EndNamedEvent throughout the engine with macros, so the events can be compiled out.

	- 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

Change 3813513 by Ben.Woodhouse

	CSV profiler refactor+ bug fix
	- Move the CSV profiler to core, so we can use it in modules other than engine
	- Profiler no longer enqueues RT commands - this is handled by a new core delegate type
	- Make begin/end requests more robust, enqueued via a command queue and processed in order
	- Defer end capture requests by a frame. This ensures stats on threads other than the gamethread (e.g. renderthread etc) are complete, so the last frame is not truncated
	- Fix long-standing bug with multiple captures where old/stale frames would appear in the first <128 frames of captures
	- Move unit stats and dynamic resolution out of the profiler itself and into the engine. Only frametime is recorded in the profiler now
	- Fix longstanding bug in first frame renderthread time in the engine

Change 3814039 by Ben.Woodhouse

	More Csvprofiler improvements
	- Event support (via CSV_EVENT macros). These appear in the "EVENTS" column of the CSV and can be used to add context to the stat data

	Fix CsvProfiler not compiling in shipping for now

Change 3814229 by Ben.Woodhouse

	Integrate + refactor of CL 3792591 to reduce complexity and fix bugs

	Original changelist description:
	CSV profiler improvements:
	- The CSV profiler is now always compiled in on the server
	- The CSV profiler can now handle both int32 and float stats
	- In BeginCapture, the function can take additional arguments for some customization of filenames

	Fixes to the above:
	 - Remove FCustomValue class
		- Fixes bug where all timestamp values from CSV_SCOPED_STATs were garbage (due to issues resulting from FCustomValue type ambiguity when adding values together)
		- FCsvCustomStat now just uses simple union + bitfield flag to reduce size and complexity (4 bytes instead of 8 per value)
		- FCsvColumn class modified to use doubles, which can represent both ints and floats without loss of precision - this class is not memory or time critical
	 - Replace multiple overrides used by the server for filenameprefix/folder/postfix etc with a single FilenameOverride

Change 3814242 by Ben.Woodhouse

Change 3817339 by Ben.Woodhouse

	Duplicate from 3816641: CSV profiler improvements
	- Added a low-pri processing thread to compress raw timing data into a much more efficient format
	   - Reduces memory usage for 15 minute 30k frame capture with GPU stats enabled from 110MB to 3.4MB
	   - Processing time : 0.1ms per frame
	- Improved name handling for char literal stats. We now use the string as the ID rather than the pointer so multiple stat uses of the same name string apply only to  a single stat
	- Reworked thread data access to eliminate locking for anything time-critical. Frame boundaries now handled via a lock-free helper class
	-  Fixed bug with queue implementation where 1 in 128 reads would duplicate the last block of stat data
	-  Reduced #include dependencies for CSVProfiler.h
	-  Removed AccumulateMax because it doesn't work, and implementing properly would add a lot of complexity
	-  Added a simple test harness

Change 3823242 by Ben.Woodhouse

	Integrate as edit from Fortnite/Main 3820067:

	Fix threading issue with D3D12 pipeline state caches for windows. This was caused by the usage of FRwScopeLock::RaiseLockToWrite. A pointer read before RaiseLockToWrite was called was invalidated because RaiseLockToWrite has to release the read lock before acquiring the write lock.

	Rename FRwScopeLock::RaiseLockToWrite to ReleaseReadOnlyLockAndAcquireWriteLock_USE_WITH_CAUTION to make it more explicit what's happening. As the comment says:

		// This function should be used with caution.
		// It releases the read lock _before_ acquiring a new write lock. This is not an atomic operation and the caller should
		// not treat it as such.
		// E.g. Pointers read from protected data structures prior to this call may be invalid after the function is called.

Change 3823840 by Ben.Woodhouse

	Edigrate from 3823816

	Also fix an issue where calling csvprofile stop twice would cause all further commands to be ignored.

	[CONSOLE] [!] Fix inverted logic and spelling of boolean.
	 - Functionally, the boolean did the correct thing, but the logic was backwards inside the build tool.

Change 3831661 by Ben.Woodhouse

	Integrate-as-edit CL 3830630 from Fortnite/Main
	Fix CSVProfiler assert in dev builds on XB1

Change 3860300 by Joe.Barnes

	Use same method for src and dest rect calculation as other post processing passes so rects match between passes. Prevents read of unprocessed pixels.

Change 3860347 by Joe.Barnes

	Delete existing SourceConfigFile before allocating a new one to prevent them leaking.

Change 3860348 by Joe.Barnes

	Completely encapsulate GetLLMAlloc() in #ifdef.

Change 3861772 by Ben.Woodhouse

	Integrate-as-edit CL 3861688 from Fortnite/Main: Forward lighting GPU crash fixes

Change 3861774 by Ben.Woodhouse

	Integrate as edit CL 3833918 from dev-rendering (courtesy of DanielW):
	D3D12 RHI: only refcount uniform buffers if GRHINeedsExtraDeletionLatency is false, which is no longer the case for PC. The refcounting was heavy on performance as reported by a licensee because FRHIResource uses atomics for refcounting, which is only necessary when GRHINeedsExtraDeletionLatency is disabled.

Change 3862214 by Ben.Woodhouse

	Integrate-as-edit CL 3859637 from Fortnite/Main
			Dynamic resolution console tweaks
			- Dynamic resolution high level switch driven by a cvar instead of code
			- Disable user settings dynamic resolution handling on non-desktop platforms. DynamicRes as a user setting does not make sense on consoles/mobile - we'll drive it from device profiles/scalability
			- Modify naming of GPUHeadRoom to make it clear that it's a percentage, not millseconds

Change 3863919 by Ben.Woodhouse

	[Copy] Integrate console dynamic resolution interface changes from CL 3863354, 3862754, 3862639

Change 3864347 by Ben.Woodhouse

	Fix the editor build. This will need a proper fix before 4.19 ships.

	This fixes the hot reload iteration speed regression without also regressing the fix to UE-42205.

	#jira UE-51472

Change 3715654 by Steve.Robb

	GitHub #4156 : Fixed not compiling template function Algo::UpperBoundBy.

Change 3718782 by Steve.Robb

Change 3735292 by Robert.Manuszewski

	Made sure component visualizer is removed from VisualizersForSelection when UnregisterComponentVisualizer() is called otherwise it may cause crashes when the engine terminates.

Change 3735332 by Steve.Robb

Change 3756778 by Ben.Marsh

	Add support for running multiple jobs simultaneously on a single builder.

	When running job or agent setup, the --num-slots=X parameter defines the number of steps that can run simultaneously (EC procedures pass in the resource step limit). A lock file is created under the workspace root (D:\Build) and a reservation file is created for the first slot that can be allocated (slot-1, slot-2, etc...).

	PR #3742: Treat RootDirectory the same way as Standardized (Contributed by TroutZhang)


Change 3764058 by Graeme.Thornton

	Generate a .code-workspace file for the current workspace. Allows foreign projects to "mount" the UE4 folder so that the engine tasks are avaible, and all engine source is visible to VSCode for searching purposes

	#jira UE-52359

Change 3764705 by Steve.Robb

	Better handling of whitespace in ImportText_Internal() for set and map properties.
	Containers are now emptied upon import failure, to avoid leaving bad container states (unhashed, partial data).
	Fix to USetProperty's temp buffer size to avoid buffer overruns.
	Duplicate map keys are now skipped during import, same as USetProperty's behavior.

Change 3764731 by Steve.Robb

	Don't re-run UHT if only source files have changed in the same folder as headers.  This was already done for hot reload, but there's no reason why it should be limited to that.

Change 3765923 by Graeme.Thornton

	VSCode - "taskName" -> "label" for C# build tasks

Change 3766018 by Steve.Robb

	constexpr constructor for TAtomic.

	ThreadSanitizer fix for UE4Delegates_Private::GNextID.

Change 3767601 by Steve.Robb

	ThreadSanitizer fix for FStats::GameThreadStatsFrame.

Change 3770567 by Ben.Marsh

	Add a FAnnotatedArchiveFormatter interface which allows querying structural type information that may not be in binary archives.

Change 3770826 by Ben.Marsh

	Move StructuredArchive implementation into Core, so primitive types can implement serialization overloads for it.

Change 3770875 by Steve.Robb

	Redundant UScriptStruct::PostLoad removed, which was causing a race condition in async loading.  This was re-establishing the CppStructOps, but that is unnecessary because native classes cannot change as a result of a load - only BP structs can, and they don't have CppStructOps.

Change 3772167 by Ben.Marsh

	Add a context-free binary formatter that can serialize tagged data. This functions as a lower-overhead binary intermediate format for JSON data.

Change 3772248 by Steve.Robb

	ThreadSanitizer fixes to FMalloc call counters.

Change 3772383 by Ben.Marsh

	Separate archive metadata from FArchive into FArchiveContext, so it can be safely exposed to consumers of FStructuredArchive.

	Add "export to text" option into the content browser asset actions context menu

Change 3772955 by Ben.Marsh

	Add a new "stream" compound type to FStructuredArchive, which allows serializing a sequence of elements similarly to an array, but without serializing an explicit size. Allows passing through data to an underlying binary archive without breaking compatibility.

Change 3772963 by Ben.Marsh

	Allow querying record keys and stream lengths from annotated archive formatters, since these archives have markup for field boundaries.

Change 3773010 by Graeme.Thornton

	Added CORE_API to FArchiveFromStructuredArchive
	Gave text asset format experimental option a slightly less random tooltip comment

Change 3773057 by Ben.Marsh

	Add a flag to FArchive to determine whether the archive is text (IsTextFormat()).

	Add support for seeking within FArchiveFromStructuredArchive. For text formats, data is serialized to an in-memory buffer, with names and objects serialized as indices into an array. For non-text formats, data is serialized directly to the underlying archive.

	Also rename FStructuredArchive::TryEnterSlot() to TryEnterField().

Change 3773118 by Steve.Robb

	TSignedIntType and TUnsignedIntType type traits for getting an integer type of a given size.

Change 3773122 by Steve.Robb

	TAtomic fixes for pointer arithmetic.
	TSignedIntType used instead of reimplementing its own trait.

Change 3773123 by Steve.Robb

	Unit tests for TAtomic.

Change 3773138 by Steve.Robb

	Run numeric tests on integer types instead of basic tests.
	Fix for compiler warnings when subtracting from unsigned atomics.

	UE4 - Fix rare crash in the pak precacher immediately after unmounting a pak file.

Change 3774426 by Ben.Marsh

	Copy all C# tools to a staging directory before compiling them. This prevents access violations when compiling tools like iPhonePackager that reference DotNETCommon, and ensures we strip NotForLicensees folders out of them all.

	See: https://answers.unrealengine.com/questions/726010/418-will-not-build-from-source.html

Change 3774658 by Ben.Marsh

	Improve error reporting while generating intellisense for project files. Include the name of the target being compiled, and allow project file generation to continue without it.

Change 3775141 by Ben.Marsh

	Always output HTML5 diagnostics at "information" verbosity, to avoid every line being prefixed with "WARNING:" and screwing up the EC postprocessor.

Change 3775459 by Ben.Marsh

	Removing .NET Framework Perforce DLL as runtime dependency of engine third party library. The actual library is linked statically.

Change 3775522 by Ben.Marsh

	UGS: Treat .uproject and .uplugin files as code changes.

Change 3775597 by Ben.Marsh

	Fix post-build steps for plugins not being executed.

	#jira UE-52754

Change 3777895 by Graeme.Thornton

	StructuredArchiveFromArchive - An adapter class for wrapping an existing FArchive with a structured archive

Change 3777931 by Graeme.Thornton

	Refactored FArchiveUObjects serialization code into some static helpers
	Added FArchiveUObjectFromStructuredArchive which allows the adaption of a structured archive into an FArchive that supports the extra UObect serialization functions for weak/soft pointers

Change 3777942 by Graeme.Thornton

	Added missing CORE_API to FStructuredArchive::FStream
	Added FStructuredArchive::FSlot insertion operator for char

Change 3782957 by Robert.Manuszewski

	UE4 - Fixed a linear search in EDL that caused performance problems for very large maps.

Change 3784503 by Ben.Marsh

	Optimizations for FStructuredArchive:

	* Store the depth explicitly in element objects, to avoid having to loop through the scope stack to find it.
	* Prevent shrinking of arrays when removing elements.
	* Add an inline allocator to the scope and container stacks.

Change 3784700 by Ben.Marsh

	Remove the inline allocator from FStructuredArchive; checking whether the inline or backup allocator is being used is slower than just allocating up-front.

	Fix for missing final values from FOREACH_ENUM_ macros.

Change 3788287 by Ben.Marsh

	TBA: Add checks in debug builds that key names in maps and records for FStructuredArchive are unique.

Change 3788678 by Ben.Marsh

	Fix compile error due to inability to instantiate TArray<> of forward declared struct. Convert set of key names to an array to avoid including Set.h in public header for FStructuredArchive.

Change 3789353 by Graeme.Thornton

	Removed unused/rotten modes from TextAsset commandlet.
	Used existing "-iterations=n" switch to control a global iteration over the given command. Useful for performance testing.

Change 3789396 by Ben.Marsh

Change 3789772 by Ben.Marsh

	Always strip trailing slashes from the end of paths specified by .build.cs files; they can cause quoted paths to be escaped on the command line.

Change 3790003 by Ben.Marsh

	TBA: Rename FStructuredArchive::EElementType::Object to FStructuredArchive::EElementType::Record.

Change 3790051 by Steve.Robb

	TBA: Return the type of a field from an annotated archive formatter at the point that we enter it, rather than querying all the time.

Change 3791489 by Graeme.Thornton

	TBA: Change StructuredArchiveFromArchive adapter to use the archive.Open() result directly, now that it's a slot and not a record

Change 3792344 by Ben.Marsh

	Improvements to base64 encoding library.

	* Now supports encoding and decoding with ANSICHAR and WIDECHAR implementations.
	* Added support for decoding base-64 blobs without padding marks.
	* Added support for decoding into pre-allocated buffer.
	* Added constexpr functions for determining the encoded and maximum decoded size of an input buffer.
	* Prevent writes past the end of allocated buffer (no longer need to manually remove padding bytes).

Change 3792949 by Ben.Marsh

	TBA: Rename FAnnotatedArchiveFormatter to FAnnotatedStructuredArchiveFormatter.

Change 3794078 by Robert.Manuszewski

	Fixing a crash that could happen when FGCObjects were constructed and destructed when shutting down the engine

	#jira UE-52392

Change 3794413 by Ben.Marsh

	TBA: Remove the element type parameter to SetScope(). It isn't really needed; we can just assume the element ID correctly identifies the item on the stack.

Change 3794731 by Ben.Marsh

	TBA: Optimize creation of stack elements for empty slots in FStructuredArchive. This saves a lot of bookkeeping when serializing a large number of individual fields. Since only one slot can be active at a time (and it only exists temporarily, until we write into it), we can just store the element ID assigned to it in a member variable.

Change 3795081 by Ben.Marsh

	UBT: Move LinuxCommon.cs into Platform/Linux folder.

Change 3795137 by Ben.Marsh

	UBT: Allow modules to specify private compiler definitions from the build.cs file, only visible within that module (via the "PrivateDefinitions" property).

	Fix path type mismatch in visual studio source code accessor meaning that the DTE comms wouldn't identify a running instance of VS as having the current solution open.

	#jira UE-53206

Change 3796315 by Ben.Marsh

	Move Formatter to the correct position for initializer.

	#jira UE-53208

Change 3797082 by Ben.Marsh

	UAT: Work around for exception thrown by launching cook with "-platform=Android_ETC1 -targetplatform=Android -cookflavor=ETC1". Anrdoid_ETC1 is not a valid platform (it's a cook platform), and can't be parsed by UAT.

	#jira UE-53232

Change 3799050 by Ben.Marsh

Change 3624590 by Steve.Robb

	AddReferencedObjects now generates a compile error with containers of UObject*s where the UObjectType is forward-declared, as these which won't be added to the reference collector.
	Tidy-up of existing calls to AddReferencedObjects.

Change 3629473 by Ben.Marsh

	Build: Rename the option for embedding source server information in PDB files for installed engine builds.

Change 3632894 by Steve.Robb

	VARARG* macros deprecated and usage replaced with variadic templates.

Change 3640704 by Steve.Robb

	MakeWeakObjectPtr added, which deduces a TWeakObjectPtr type from a raw pointer type.
	Fix to TWeakObjectPtr's constructor which implicitly removed const.
	Fixes to everything which didn't compile as a result.

Change 3650813 by Graeme.Thornton

	Removed FStartupPackages and associated code

Change 3651000 by Ben.Marsh

	Return the stack size from FPlatformStackWalk::CaptureStackBacktrace() rather than checking for the first null pointer, to prevent truncated callstacks if parts of the stack are zeroed out.

	#jira UE-49980

Change 3690842 by Steve.Robb

	FPlatformAtomics::AtomicRead added - needs optimizing.

	VS debugger visualizers for TAtomic.

Change 3732270 by Steve.Robb

	Relaxed stores and loads.

Change 3749315 by Graeme.Thornton

	If UAT is invoked with platforms in both the -platform and -targetplatform command line switches, build using all of them rather than just the ones in -targetplatform

	#jira UE-52034

Change 3750657 by Josh.Engebretson

	Fixed issue when debugging editor cook/package and project launch operations

	#jira UE-52207

	ENamedThreads::RenderThread and ENamedThreads::RenderThread_Local encapsulated by getters and setters.

Change 3770549 by Steve.Robb

	Removal of obsolete PLATFORM_COMPILER_HAS_DEFAULTED_FUNCTIONS and PLATFORM_COMPILER_HAS_AUTO_RETURN_TYPES.
	Tidy up of existing code which uses it.

Change 3770553 by Ben.Marsh

	Adding structured serialization API to Core/CoreUObject for use with text-based assets.

	* FStructuredArchive abstracts an archive which is made up of compound types (records, arrays, and maps). Values are stored in slots within these types.
	* Records are string -> value dictionaries where the key names can be compiled out in non-editor builds or when WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Maps are string -> value dictionaries where the key names are present regardless of the build type.
	* Proxy objects are defined to express the context for serialization (FStructuredArchive::FRecord, FStructuredArchive::FArray, FStructuredArchive::FMap, FStructuredArchive::FSlot) which allows basic validation through static typing. These objects act as lightweight handles, and can be cheaply constructed and passed around on the stack. Most serialization to and from the archive is done through these objects.
	* Runtime checks perform additional validation to ensure that serialized data is well formed and written in a forward-only manner, regardless of the underlying archive type.
	* The actual input/output format is determined by a separate interface (FArchiveFormatter). Context validation (always causing matching LeaveArray for every EnterArray, etc...) is done by FStructuredArchive, so implementing these classes is fairly trivial. FArchiveFormatter can be de-virtualized in non-editor builds, where WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Includes implementations of FArchiveFormatter for binary and JSON formats.

Change 3771105 by Steve.Robb

	Deprecation warnings for PLATFORM_COMPILER_HAS_AUTO_RETURN_TYPES and PLATFORM_COMPILER_HAS_DEFAULTED_FUNCTIONS.
	Fix for incorrect warning formatting on Clang platforms.

Change 3771520 by Steve.Robb

	Start moving Clang-using platforms' pre-setup stuff into a Clang-specific header.

Change 3771564 by Steve.Robb

	More common macros moved to the Clang pre-setup header.

Change 3771613 by Steve.Robb

	EMIT_CUSTOM_WARNING_AT_LINE moved to ClangPlatformCompilerPreSetup.h.

Change 3772881 by Ben.Marsh

	Add support for serializing FName and UObject through FStructuredArchive.

	In order to allow custom linker behavior when serializing objects:

	* The constructor to JSON input formatter now takes a delegate to convert a string object name into a UObject pointer.
	* The constructor to tagged binary formatter takes a delegate to serialize a UObject pointer into any form it chooses (likely an integer index into the import table)

	Object and name types are stored as strings in JSON, using an "Object:" or "Name:" prefix to differentiate them from regular strings. Any strings that already contain one of these prefixes are prepended with a "String:" prefix (as is any string that already has a "String:" prefix).

Change 3772941 by Graeme.Thornton

	Make build work when including StructuredArchive.h from core container types
	Added standard header to new files
	Add structured archive serializer for TArray
	Fix bug in structured archive where containers weren't being popped from the scope stack

Change 3772972 by Ben.Marsh

	Add an adapter which presents a legacy FArchive interface to a FStructuredArchive slot.

	Data is serialized into this slot as a stream of elements; raw data is buffered up into fixed size chunks, names and objects are serialized separately.

	When used with FBinaryArchiveFormatter, this should result in all data being passed through to the underlying archive in a backwards compatible way, wiith no additional bookkeeping fields.

Change 3773006 by Ben.Marsh

	Rename FStructuredArchive::FRecord::EnterSlot() to EnterField().

Change 3773013 by Steve.Robb

	bUseInlining target rule added to UnrealBuildTool, which defaults to true, to allow inlining to be disabled for debugging purposes.

Change 3774499 by Ben.Marsh

	Minor fixes for FStructuredArchive related classes:

	* Text-based archive formats are now compiled out when WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Fixed issue with FTaggedBinaryArchiveFormatter state becoming corrupted when looking ahead at field types.
	* FArchiveFieldName constructor is now explicit, to fix cases where strings were being passed directly to serialize functions.

Change 3774600 by Ben.Marsh

	Add CopyFormattedData() function, which can copy data from one formatter to another. Add a test case to SerializationAPI that converts from data -> JSON -> binary -> JSON -> data.

	This function can be used to implement a generic visitor pattern, by implementing a FArchiveFormatter which receives the deserialized data.

Change 3789721 by Ben.Marsh

	TBA: Split FTaggedBinaryArchiveFormatter into separate classes for reading and writing.

Change 3789920 by Ben.Marsh

	TBA: Support automatic coercion between any numeric types in tagged binary archives. Also report the smallest type that can contain a value, rather than just in32/double.

	#jira UECORE-364

Change 3789982 by Ben.Marsh

	TBA: Change FStructuredArchive::Open() to return a slot, rather than a record, to make it easier to implement a raw FArchive adapter.

Change 3792466 by Ben.Marsh

	TBA: Better handling of raw data in text based assets. Short sequences of binary data are Base64 encoded as a single string. Longer sequences are stored as an array of Base64 encoded lines, push a SHA1 hash to detect cases where the data was merged incorrectly.

	In order to allow inference of the correct type for a field, other fields called "Base64" will be escaped to "_Base64", and any field beginning with "_" will have an additional underscore inserted. Reading files back in reverses these transformations.

Change 3792935 by Ben.Marsh

	TBA: Rename FArchiveFormatter to FStructuredArchiveFormatter for consistency with FStructuredArchive.

Change 3795100 by Ben.Marsh

	UBT: Rename the ModuleRules Definitions property to PublicDefinitions, to make its semantics clearer.

Change 3795106 by Ben.Marsh

	Replace all internal usages of ModuleRules.Definitions, and replace it with ModuleRules.PublicDefinitions.

Change 3796275 by Ben.Marsh

	Fix paths to Version.h includes from resource files.

Change 3800683 by Josh.Engebretson

	Remove WER from Mac and Linux crash reports in favor of unified runtime-xml format
	#jira UE-50073

Change 3803545 by Steve.Robb

	TWeakObjPtr const-dropping assignment fix.
	Fixes to change.

	UE-49301 Text in UMG controls flickers during update from Virtual Keyboard
	#jira UE-49301
	#ue4
	#android

	On some Android devices TextWatcher.onTextChanged gets called multiple times when typing/deleting the content of a EditText (internally, the first call resets the entire content, the second fills it with the new value)
	The workaround is to delays sending "empty string" to the Slate, waiting for 100ms to see if there is a second call (the "real" string to update)

	The CL contains a fix for a 5/5 crash : select some/all the text from the native edittext, press delete.

Change 3720654 by Sorin.Gradinaru

	UE-48499 Android Voice Module has a few issues
	#jira 48499
	#Android
	#ue4

	1.Circular Buffer:  Does the engine already have an implementation? Do we want this into core libraries?
	R: There is an generic template class TCircularBuffer, but it lacks functionality like write/read checks, reading/writing data chunks.
	Plus the code from VoiceModuleAndroid is optimized for circular byte array. I suggest to keep it.

	2. Possible memory leaks: void free_circular_buffer (circular_buffer *p) is implemented, but not used. Presumably a memory leak on the variable inrb. Does CreateAudioRecorder need to be paired with any kind of destroy on shutdown?
	R: Fixed. Using an array ActiveVoiceCaptures to store VoiceCapture references (same as on Windows)

	3. Init() There are 4 calls to setup/init things that store the result in "result" but only the last call is checked against success. Should more checks against the values be made at each stage with informative log messaging in the event of failure?
	R: Fixed.

	4. GetVoiceData()
	// Workaround for dealing with noise after stand-by
	while(bytes<InVoiceBufferSize)
	{
		OutVoiceBuffer[bytes++]=0;
	}
	Isn't this just a memzero?
	R: Fixed.

	5. Missing features. Need to implement GetBufferSize and DumpState
	R: Added GetBufferSize. Can be used like in TestVoice.cpp
	DumpState is never used (same on Mac, iOS), plus the OpenSL objects do not expose internal properties.

Change 3589827 by Graeme.Thornton

	More fixes for VSCode project generation and for UBT running on .NET Core
	 - Use a different file extension for rules assemblies when build on .NET Core, so they never get used by their counterparts
	 - UEConsoleTraceListener supports stdout/stderror constructor parameter and outputs to the appropriate channel
	 - Added documentation for UEConsoleTraceListener
	 - All platforms .NET project compilation tasks/launch configs now use "dotnet" and not the normal batch files
	 - Restored the default UBT log verbosity to "Log" rather than "VeryVeryVerbose"
	 - Renamed assemblies for .NETCore versions of DotNETUtilities and UnrealBuildTool so they don't conflict with the output of the existing .NET Desktop Framework stuff

Change 3589868 by Graeme.Thornton

	Separate .NET Core projects for UBT and DotNETCommon out into their own directories so that their intermediates don't overlap with the standard .NET builds, causing failures.

	UBT registers ONLY .NET Core C# projects when generating VSCode solutions, and ONLY standard C# projects in all other cases

Change 3589919 by Robert.Manuszewski

	Fixing crash when cooking textures that have already been cooked for EDL (support for cooked content in the editor)

Change 3589940 by Graeme.Thornton

	Force UBT to think it's running on mono when actually running on .NET Core. Disables a lot of windows specific code paths.

	Fully disable automatic assembly info generation in .NET Core projects

Change 3590534 by Robert.Manuszewski

	Marking UObject as intrinsic clas to fix a crash on UFE startup.

	Move Windows event log code into cpp file, and expose it to other modules even if it's not enabled by default.

Change 3592767 by Gil.Gribb

	UE4 - Changed the logic so that engine UObjects boot before anything else. The engine classes are known to be cycle-free, so we will get them done before moving onto game modules.

Change 3592770 by Gil.Gribb

	UE4 - Fixed a race condition with async read completion in the prescence of cancels.

Change 3593090 by Steve.Robb

	Tool which takes a .map file and a .objmap file (from UBT) and creates a report which shows the size of all the symbols contributed by the source code per-folder.

Change 3596807 by Ben.Marsh

	Improve Intellisense when generated headers are missing or out of date (eg. line numbers changed, etc...). These errors seem to be masked by VAX, but are present when using the default Visual Studio Intellisense.

	* UCLASS macro is defined to empty when __INTELLISENSE__ is defined. Previous macro was preventing any following class declaration being parsed correctly if generated code was out of date, causing squiggles over all class methods/variables.
	* Insert a semicolon after each expanded GENERATED_BODY macro, so that if it parses incorrectly, the compiler can still continue parsing the next declaration.

Change 3596957 by Steve.Robb

	UBT can be used to write out an .objsrcmap file for use with the MapFileParser.
	Renaming of ObjMap to ObjSrcMap in MapFileParser.

Change 3597982 by Ben.Marsh

	Add an option to allow overriding the local DDC path from the editor (under Editor Preferences > Global > Local Derived Data Cache).

	#jira UE-47173

Change 3598045 by Ben.Marsh

	UGS: Add variables for stream and client name, and the ability to escape any variables for URIs using the syntax $(VariableName:URI).

	Enable intellisense generation for VS Code project files and setup include paths properly

Change 3601762 by Ben.Marsh

	UBT: Add support for adaptive non-unity builds when working from a Git repository.

	The ISourceFileWorkingSet interface is now used to query files belonging to the working set, and has separate implementations for Perforce (PerforceSourceFileWorkingSet) and Git (GitSourceFileWorkingSet). The Git implementation is used if a .git directory is found in the directory containing the Engine folder, the directory containing the project file, or the parent directory of the project file, and spawns a "git status" process in the background to determine which files are untracked or staged.

	Several new settings are supported in BuildConfiguration.xml to allow modifying default behavior:

	<SourceFileWorkingSet>
	    <Provider>Default</Provider> <!-- May be None, Default, Git or Perforce -->
	    <RepositoryPath></RepositoryPath> <!-- Specifies the path to the repository, relative to the directory containing the Engine folder. If not set, tries to find a .git directory in the locations listed above. -->
	    <GitPath>git</GitPath> <!-- Specifies the path to the Git executable. Defaults to "git", which assumes that it will be on the PATH -->
	</SourceFileWorkingSet>

Change 3604032 by Graeme.Thornton

	Disabled optimizations around FShooterStyle::Create(), which was crashing in Win64 shipping game builds due to some known compiler issue. Same variety of fix as BenZ did in CL 3567741.

Change 3607026 by James.Hopkin

Change 3612471 by Ben.Marsh

	UBT: Move FastJSON into DotNETUtilities.

Change 3613479 by Ben.Marsh

	UBT: Remove the bIsCodeProject flag from UProjectInfo. This was only really being used to determine which projects to generate an IDE project for, so it is now checked in the project file generator.

Change 3613910 by Ben.Marsh

	UBT: Remove unnecessary code to guess a project from the target name; doesn't work due to init order, actual project is determined later.

Change 3614075 by Ben.Marsh

	UBT: Remove hacks for testing project file attributes by name.

Change 3614090 by Ben.Marsh

	UBT: Remove global lookup of project by name. Projects should be explicitly specified by path when necessary.

Change 3614962 by Ben.Marsh

	UBT: Move the VS2017 strict conformance mode (/permissive-) behind a command line option (-Strict), and disable it by default. Building with this mode is not guaranteed to work correctly without updated Windows headers.

Change 3615416 by Ben.Marsh

	EC: Include an icon showing the overall status of a build in the grid view.

Change 3615713 by Ben.Marsh

	UBT: Delete any files in output directories which match output files in other directories. Allows automatically deleting build products which are moved into another folder.

	#jira UE-48987

Change 3616652 by Ben.Marsh

	Plugins: Fix incorrect dialog when binaries for a plugin are missing. Should only prompt to disable if starting a content-only project.

	#jira UE-49007

Change 3616680 by Ben.Marsh

	Add the CodeAPI-HTML.tgz file into the installed engine build.

Change 3616767 by Ben.Marsh

	Plugins: Tweak error message if the FModuleManager::IsUpToDate() function returns false for a plugin module; the module may be missing, not just incompatible.

Change 3616864 by Ben.Marsh

	Cap the length of the temporary package name during save, to prevent excessively long filenames going over the limit once a GUID is appended.

	#jira UE-48711

Change 3619964 by Ben.Marsh

	UnrealVS: Fix single file compile for foreign projects, where the command line contains $(SolutionDir) and $(ProjectName) variables.

Change 3548930 by Ben.Marsh

	UBT: Remove UEBuildModuleCSDLL; there is no codepath that still supports creating them. Remove the remaining UEBuildModule/UEBuildModuleCPP abstraction.

Change 3558056 by Ben.Marsh

	Deprecate FString::Trim() and FString::TrimTrailing(), and replace them with separate versions to mutate (TrimStartInline(), TrimEndInline()) or return by copy (TrimStart(), TrimEnd()).

Change 3572811 by Ben.Marsh

	UBT: Add -enableasan / -enabletsan command line options and bEnableAddressSanitizer / bEnableThreadSanitizer settings in BuildConfiguration.xml (and remove environment variables).

Change 3573397 by Ben.Marsh

	UBT: Create a <ExeName>.version file for every target built by UBT, in the same JSON format as Engine/Build/Build.version. This allows monolithic targets to read a version number at runtime, unlike when it's embedded in a modules file, and allows creating versioned client executables that will work with versioned servers when syncing through UGS.

Change 3575659 by Ben.Marsh

	Remove CHM API documentation.

Change 3582103 by Graeme.Thornton

	Simple ResX writer implemetation that the xbox deloyment code can use instead of the one from the windows forms assembly, which isn't supported on .NET Core

	Removed reference to System.Windows.Form from UBT.

Change 3584113 by Ben.Marsh

	Fixed a build error in the WEX automation library

Change 3590034 by Ben.Marsh

	Move functionality related to windowing and input out of the Core module and into an ApplicationCore module, so it is possible to build utilities with Core without adding dependencies on XInput (Windows), SDL (Linux), and OpenGL (Mac).

Change 3593754 by Steve.Robb

	Fix for tuple debugger visualization.

Change 3597208 by Ben.Marsh

	Move CrashReporter out of a public folder; it's not in a form that is usable by subscribers and licensees.

Change 3600163 by Ben.Marsh

	UBT: Simplify how targets are cleaned. Delete all intermediate folders for a platform/configuration, and delete any build products matching the UE4 naming convention for that target, rather than relying on the current build configuration or list of previous build products. This will ensure that build products which are no longer being generated will also be cleaned.

	#jira UE-46725

Change 3604279 by Graeme.Thornton

	Move pre/post garbage collection delegates into accessor functions so they can be used by globally constructed objects

Change 3606685 by James.Hopkin

	Also removed redundant 'IsA's from AnimationRetargetContent::AddRemappedAsset in EditorAnimUtils.cpp.

Change 3610950 by Ben.Marsh

	UAT: Simplify logic for detecting Perforce settings, using environment variables if they are set, otherwise falling back to detecting them. Removes special cases for build machines, and makes it simpler to set up UAT commands on builders outside Epic.

Change 3610991 by Ben.Marsh

	UAT: Use the correct P4 settings to detect settings if only some parameters are specified on the command line.

Change 3612342 by Ben.Marsh

	UBT: Change JsonObject.Read() to take a FileReference parameter.

Change 3612362 by Ben.Marsh

	UBT: Remove some more cases of paths being passed as strings rather than using FileReference objects.

Change 3619128 by Ben.Marsh

	Include builder warnings and errors in the notification emails for automated tests, otherwise it's difficult to track down non-test failures.

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

	Only use the recursion guard in async loading code when the event driven loader is enabled.

Change 3498112 by Ben.Marsh

	UBT: Respect the option to not create debug info in the Android toolchain. This option is already being respected by the compiler, but the linker adds debug info of its own.

Change 3500239 by Robert.Manuszewski

	Made sure the Super Class token stream is also locked when assembling Class token stream with async loading thread enabled. This to to prevent race conditions when loading BP classes.

Change 3500395 by Steve.Robb

	Extra codegen savings when not in hot reload.

Change 3501004 by Steve.Robb

	EObjectFlags now have constexpr operators.

Change 3502079 by Ben.Marsh

Change 3502527 by Steve.Robb

	Fix for zero-sized array compile error in generated code when all functions are editor-only.

Change 3502542 by Ben.Marsh

	UAT: Remove the custom source parameter from log functions, and add support for a customizable indent instead.

Change 3502868 by Steve.Robb

	Workaround for inefficient generated code with stateless lambdas on Clang.

Change 3503550 by Steve.Robb

Change 3504712 by Ben.Marsh

	UAT: Less spammy log and error output from UAT.

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

Change 3504808 by Ben.Marsh

	UAT: Suppress P4 output when running a recursive instance of UAT.

Change 3505044 by Steve.Robb

	Code generation improved for TCppClassType code.

	Fix deterministic cooking issue; always use a pseudo-random number stream when compiling a module.

Change 3505699 by Ben.Marsh

	Plugins: Store the bEnabledByDefault flag exactly as it was read from disk rather than collapsing it to an absolute value based on the default for the location it was read from. This allows loading/saving plugin descriptors without any knowledge of whether they are game or engine plugins.

Change 3506055 by Ben.Marsh

	UAT: Add a class to apply a log indent for the lifetime of an object (ScopedLogIndent), and use it to apply an indent to MegaXGE/ParallelExecutor output.

Change 3507745 by Robert.Manuszewski

	Moved FSimpleObjectReferenceCollectorArchive and FSimpleObjectReferenceCollectorArchive to be internal archives used only by FReferenceCollector so that they are constructed only once per GC task instead of potentially multiple times per GC (as was the case with UDataTables and BlueprintGeneratedClasses).

Change 3507911 by Ben.Marsh

	Plugins: Minor changes to plugin descriptors.

	* Add a distinct setting for an unspecified EnabledByDefault setting in plugin descriptors.
	* Add a function to IPlugin to determine the effective EnabledByDefault setting, based on where the plugin was loaded from.

Change 3508669 by Ben.Marsh

	EC: Parse multi-line messages from UBT and UAT.

Change 3508691 by Ben.Marsh

	Fix for mismatched stat categories in AudioMixer.

	#jira UE-46129

Change 3509289 by Robert.Manuszewski

	Custom Version Container will no longer be always constructed in FArchive constructor. This reduces the number of the Custom Version Container allocations considerably.

Change 3509294 by Robert.Manuszewski

	UDataTable::AddReferencedObjects will no longer try to iterate over the RowMap if there's no UObject references in it.

Change 3509312 by Steve.Robb

	Check improved for Append() to allow nullptr in empty ranges, and added to new constructor too.

	#jira UE-46136

Change 3509396 by Steve.Robb

	GitHub# 3676: Fix TUnion operator<< compile error

	Fixed up unsoilicited files getting populated with files which aren't finished being created yet.

	#test None

Change 3510594 by Daniel.Lamb

	Fixed up temp files directory for patching.

	Thanks David Yerkess @ Milestone
	#review@Ben.Marsh

Change 3511628 by Ben.Marsh

	PR #3707: Fixed UBT stack size (Contributed by gildor2)


Change 3511808 by Ben.Marsh

	Optimize checks for whether the game project contains source code. Now stops as soon as the first file is found and ignores directories beginning with a '.' character (eg. .git)

	#jira UE-46540

Change 3512017 by Ben.Marsh

	Plugins: Deprecate the QueryStatusForAllPlugins() function; the same functionality is available via the IPlugin interface.

Change 3513935 by Steve.Robb

	Reverted array iteration in FPropertyNode::PropagatePropertyChange as this is now covered in TProperty::InitializeValueInternal() as of CL# 3293477.

Change 3514142 by Steve.Robb

	MemoryProfiler2 added to generated solution.

Change 3516463 by Ben.Marsh

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

Change 3517860 by Ben.Marsh

	PR #3727: FString Dereference Fixes (Contributed by jovisgCL)


Change 3517967 by Ben.Marsh

Change 3520083 by Steve.Robb

	Force a GC after hot reload to clean up reinstanced objects which may still tick.

	#jira UE-40421

Change 3520480 by Robert.Manuszewski

	Improved assert message when the initial package read request was too small.

Change 3520590 by Graeme.Thornton

	SignedArchiveReader optimizations
	 - Loads more stats
	 - Stop chunk cache worker from waking up continuously to poll for work. Only wake up when triggered by the archive reader
	 - Signed archive reader just yields when waiting for buffers to finish loading, rather than sleeping for some arbitrary amount of time
	 - Track the number of pending read requests in an atomic counter, to save having to lock the request queue to check for new entries

Change 3521023 by Graeme.Thornton

	Remove spin from signed archive reader. Main thread waits on an event triggered by the chunk worker to indicate that new chunks are ready for processing

Change 3521787 by Ben.Marsh

	PR #3736: Small static code analysis fixes (Contributed by jovisgCL)


Change 3521789 by Ben.Marsh

	PR #3735: Fix case sensitivity issue in FWindowsPlatformProcess::IsApplicationRunning. (Contributed by samhocevar)


Change 3524721 by Ben.Marsh

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

Change 3524741 by Ben.Marsh

	Move PumpMessages() into FPlatformApplicationMisc.

Change 3525399 by Ben.Marsh

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

Change 3525743 by Ben.Marsh

	UAT: Add a parameter to allow updating version files without updating Version.h, to allow faster link times on incremental builds.

Change 3525746 by Ben.Marsh

	EC: Include the clobber option on new workspaces, to allow overriding version files when syncing.

Change 3526453 by Ben.Marsh

	UGS: Do not generate project files when syncing precompiled binaries.

Change 3527045 by Ben.Marsh

	Fix hot reload generating import libraries without DLLs. Now that they are produced by separate actions by default, it was removing DLLs from the action graph due to the bSkipLinkingWhenNothingToCompile setting.

Change 3527420 by Ben.Marsh

	UGS: Add additional search paths for UGS config files, and fix a few cosmetic issues (inability to display ampersands in tools menu, showing changelist -1 when running a tool without syncing).

	Config files are now read from:

	Engine/Programs/UnrealGameSync/UnrealGameSync.ini
	Engine/Programs/UnrealGameSync/NotForLicensees/UnrealGameSync.ini

	If a project is selected:

	<ProjectDir>/Build/UnrealGameSync.ini
	<ProjectDir>/Build/NotForLicensees/UnrealGameSync.ini

	If the .uprojectdirs file is selected:

	Engine/Programs/UnrealGameSync/DefaultProject.ini
	Engine/Programs/UnrealGameSync/NotForLicensees/DefaultProject.ini

Change 3528063 by Ben.Marsh

	Fix non-thread safe construction of FPluginManager singleton. Length of time spent in the constructor resulted in multiple instances being constructed at startup, making the time to enumerate plugins on slow media significantly worse.

Change 3528415 by Ben.Marsh

	UAT: Remove \r characters from the end of multiline log messages.

Change 3528427 by Ben.Marsh

	EC: Fix spaces being converted to tabs at start of line in failure emails (by Gmail), and wrap following lines at the same indent.

Change 3528485 by Ben.Marsh

	EC: Remove zero-width word break characters from slashes in notification emails; can cause really hard to debug problems when copy pasted into other places.

Change 3528505 by Steve.Robb

	PR #3755: MallocProfiler - Remove subfolder from profiling save directory (Contributed by Josef-CL)


	#jira UE-46819

	PR #3760: Fix typo (Contributed by jesseyeh)


Change 3528792 by Steve.Robb

	PR #3764: MallocProfiler - Refactoring Scopelock (Contributed by Josef-CL)


	#jira UE-46962

Change 3528941 by Robert.Manuszewski

	Fixed lazy object pointers not being updated for streaming sub-levels in PIE. Fixed lazy pointers returning object that is still being loaded which could lead to undefined behavior when client code started modifying the returned object.

	#jira UE-44996

Change 3530241 by Ben.Marsh

	UAT: Only pass -submit or -nosubmit to child instances of UAT if they were specified on the original command line. BuildCookRun uses this flag to determine whether to submit, rather than just whether to allow submitting, so we shouldn't pass an inferred value.

Change 3531377 by Ben.Marsh

	Plugins: Allow plugins to specify a list of supported target platforms, which is propagated to any .uproject file that enables it.

	This has several advantages over the per-module platform whitelist/blacklist:

	* Platform-specific .uplugin files can now be excluded when staging other platforms. Previously, it was only possible to determine which platforms a plugin supports by reading the plugin descriptor itself. Now that information is copied into the .uproject file, so the runtime knows which plugins to ignore.
	* References to dependent plugins from platform-specific plugins can now be eliminated.
	* Plugins containing content can now be unambiguously disabled on a per-platform basis (having no modules for a platform does not confer that a plugin doesn't support that platform; now it is possible to specify supported platforms explicitly).
	* The editor can load any plugins without having to whitelist supported editor host platforms.

	UE4 targets which support loading plugins for target platforms can set TargetRules.bIncludePluginsForTargetPlatforms (true for the editor by default, false for any other target types). This defines the LOAD_PLUGINS_FOR_TARGET_PLATFORMS macro at runtime, which allows the plugin system to filter which plugins to look for at runtime.

	Any .uproject file will be updated at startup to contain the list of supported platforms for each referenced plugin if necessary.

Change 3531502 by Jin.Zhang

	Add support for GPUCrash #rb

Change 3531664 by Ben.Marsh

	UBT: Change output format from C# JSON writer to match output by the engine.

Change 3531848 by Ben.Marsh

	UAT: Add script to resaving all project descriptors under a folder, embedding information for any supported platforms for the plugins they enable.

Change 3531869 by Ben.Marsh

	UAT: Add parameter to the ResaveProjectDescriptors command to update the engine association field.

Change 3532474 by Ben.Marsh

	UBT: Use the same mechanism as UAT for logging exceptions.

Change 3532734 by Graeme.Thornton

	Initial VSCode Support
	 - Tasks generated for building all game/engine/program targets
	 - Debugging support for targets on Win64

Change 3532789 by Steve.Robb

	FScriptSet::Add and TScriptMap::Add now replace the element, matching the behavior of TSet and TMap.
	Set_Add and Map_Add no longer have a return value.
	FScriptSet::Find and FScriptMap::Find functions are now FindIndex.
	FScriptSetHelper::FindElementFromHash is now FindElementIndexFromHash.

Change 3532845 by Steve.Robb

	Obsolete UHT settings deleted.

Change 3532875 by Graeme.Thornton

	VSCode
	 - Add debug targets for different target configurations
	 - Choose between VS debugger (windows) and GDB (mac/linux)

Change 3532906 by Graeme.Thornton

	VSCode
	 - Point all builds directly at UBT rather than the batch files
	 - Adjust mac build tasks to run through mono

Change 3532924 by Ben.Marsh

	UAT: Set the UAT working directory immediately on startup. This ensures that any command line arguments containing paths are resolved consistently to the branch root.

Change 3535234 by Graeme.Thornton

	VSCode - Pass intellisense system a list of paths to use for header resolution

Change 3535247 by Graeme.Thornton

	UBT - Add a ToString to ProjectFile.Source file to help with debugger watch presentation

Change 3535376 by Graeme.Thornton

	VSCode
	 - Added build jobs for C# projects
	 - Linked launch tasks to relevant build task

Change 3537083 by Ben.Marsh

	EC: Change P4 swarm links to start at the changelist for a build.

Change 3537368 by Graeme.Thornton

	Fix for crash in FSignedArchiveReader when multithreading is disabled

Change 3537550 by Graeme.Thornton

	Fixed a crash in the taskgraph when running single threaded

Change 3537922 by Steve.Robb

Change 3539691 by Graeme.Thornton

	VSCode - Various updates to get PC and Mac C++ projects building and debugging.
	 - Some other changes to C# setup to allow compilation. Debugging doesn't work.

Change 3539775 by Ben.Marsh

	Plugins: Various fixes to settings for enabling plugins.

	* Fix crash on startup when trying to disable a missing plugin (was keeping pointers to elements in the project's plugin reference array, which may be modified if a plugin is disabled).
	* Revert fix to set PluginDescriptor.bRequiresBuildPlatform = true by default. This was the originally intended behavior, but it was accidentally defaulted to false during serialization unless specified in the .uplugin file. Many plugins may rely on this behavior (they may not declare asset classes otherwise, for example, which could result in loss of data), so change the default value to false instead. Also fixes popups to disable platform-specific plugins if platform SDKs are not installed.
	* Fix plugins which are referenced but do not exist not showing the appropriate prompt to disable them.

Change 3540788 by Ben.Marsh

	UBT: Add support for declaring custom pre-build steps and post-build steps from .target.cs files. Similarly to the custom build steps configurable from .uproject and .uplugin files, these specify commands which will be executed by the host platform's shell before or after a build. The following variables are expanded within the list of commands before execution: $(EngineDir), $(ProjectDir), $(TargetName), $(TargetPlatform), $(TargetConfiguration), $(TargetType), $(ProjectFile).

	Example usage:

	public class UnrealPakTarget : TargetRules
	{
		public UnrealPakTarget(TargetInfo Target) : base(Target)
		{
			Type = TargetType.Program;
			LinkType = TargetLinkType.Monolithic;
			LaunchModuleName = "UnrealPak";

			if(HostPlatform == UnrealTargetPlatform.Win64)
			{
				PreBuildSteps.Add("echo Before building:");
				PreBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");

				PostBuildSteps.Add("echo After building!");
				PostBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");
			}
		}
	}

	Add callback into FMacPlatformMisc::PumpMessages() from FMacPlatformApplicationMisc::PumpMessages().

	#jira UE-47449

Change 3545954 by Gil.Gribb

	Fixed a critical crash bug relating to a race condition in async package summary reading.

Change 3545968 by Ben.Marsh

	UAT: Fix incorrect username in BuildGraph <Submit> task. Should use the username from the Perforce environment, not assume the logged in user name is the same.

	#jira UE-47419

Change 3545976 by Ben.Marsh

	EC: Delete the AutoSDK client if the directory doesn't exist. When we format build machines, we need to force everything to be resynced from scratch.

Change 3546185 by Ben.Marsh

	Hacky fix for deployment on IOS/TVOS. Since deployment directly references the NonUFS manifest files that are written out, merge all the SystemNonUFS files back into the NonUFS list after the regular NonUFS files have been remapped.

Change 3547084 by Gil.Gribb

	Fixed a critical race condition in the new async loader. This was only reproducible on IOS, but may affect other platforms.

Change 3547968 by Gil.Gribb

	Fixed critical race which potentially could cause a crash in the pak precacher.

Change 3504722 by Ben.Marsh

	BuildGraph: Improved tracing for error messages. All errors are now propagated as exceptions, and are tagged with additional context information about the task currently being run.

	For example, throwing new AutomationException("Unable to write foo.txt") from SetVersionTask.Execute is now displayed in the log as:

	ERROR: Unable to write to foo.txt
	         while executing <SetVersion Change="0" CompatibleChange="0" Branch="Unknown" Promoted="True" />
	         at Engine\Build\InstalledEngineBuild.xml(91)
	       (see D:\P4 UE4\Engine\Programs\AutomationTool\Saved\Logs\UAT_Log.txt for full exception trace)

Change 3512255 by Ben.Marsh

	Rename FPaths functions with a "Game" prefix (GameDir(), GameContentDir(), etc...) to have a "Project" prefix (ProjectDir(), ProjectContentDir(), etc...) for clarity with non-game uses of UE4. Old functions still exist but are deprecated.

Change 3512332 by Ben.Marsh

	Rename "Game" functions in FApp to be "Project" functions (FApp::GetGameName() -> FApp::GetProjectName(), etc...) for clarity with non-game uses of UE4.

Change 3512393 by Ben.Marsh

	Rename FPaths::GameLogDir() to FPaths::ProjectLogDir().

Change 3513452 by Ben.Marsh

	Plugins: Rename EPluginLoadedFrom::GameProject to EPluginLoadedFrom::Project.

Change 3516262 by Ben.Marsh

	Add support for a "Mods" folder distinct from the project's "Plugins" folder, instead of using the bIsMod flag on the plugin descriptor.

	* Mods are enumerated similarly to regular plugins, but IPlugin::GetType() will return EPluginType::Mod.
	* The DLCName parameter to BuildCookRun and the cooker now correctly finds any plugin in the Plugins or Mods directory (or any subfolders).

Change 3517565 by Ben.Marsh

	Remove fixed engine version numbers from OSS plugins.

Change 3518005 by Ben.Marsh

	UAT: Remove the bUFSFile parameter from DeployLowerCaseFilenames(). Every platform returns false if the argument is false.

Change 3518054 by Ben.Marsh

	UAT: Use an enum to direct whether all directories should be searched when finding files to stage, rather than a bool. Having so many optional boolean arguments makes code unreadable and refactoring hard.

Change 3524496 by Ben.Marsh

	Start moving GUI application code into a separate static platform class, hopefully ultimately removing it from Core.

Change 3524641 by Ben.Marsh

	Move more functionality related to windowed/graphical applications into FPlatformApplicationMisc.

Change 3528723 by Steve.Robb

	MoveTemp now static asserts if passed a const reference or rvalue.
	MoveTempIfPossible still follows the old (std::move) rule, which is useful for templates where the nature of the argument is not obvious.
	Fixes to violations of these new rules.

Change 3528876 by Ben.Marsh

	Move FPlatformMisc::ClipboardCopy and FPlatformMisc::ClipboardPaste to FPlatformApplicationMisc::ClipboardCopy and FPlatformApplicationMisc::ClipboardPaste.

Change 3529073 by Ben.Marsh

	Add script to package ShooterGame for any platforms.

Change 3531493 by Ben.Marsh

	Update platform-specific plugins to declare the target platforms they support.

Change 3531611 by Ben.Marsh

	UAT: Add a ResavePluginDescriptors command, which resaves all plugin descriptors under a given folder, removing any outdated fields and rewrites them in a consistent style. Many plugins in the wild contain redundant or no-longer used fields due to using our plugins as templates.

Change 3531868 by Ben.Marsh

	Resaving project descriptors to remove invalid fields.

Change 3531983 by Ben.Marsh

	UAT: Simplify logic for staging code, and add validation against shipping files in restricted folders.

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

Change 3540315 by Ben.Marsh

	UAT: Moving StreamCopyDescription command into a NotForLicensees folder, since it's only meant to be used by engine developers.

Change 3542410 by Ben.Marsh

	UBT: Deprecate accessing properties through BuildConfiguration.* or UEBuildConfiguration.* from .target.cs files. These have been aliases to the current TargetRules instance for several releases already.

Change 3543018 by Ben.Marsh

	UBT: Deprecate the BuildConfiguration and UEBuildConfiguration aliases from the ModuleRules class. These have been implemented as an alias ot the ReadOnlyTargetRules instance passed to the constructor for several engine versions.

Change 3544371 by Steve.Robb

	Fixes to TSet_Add and TMap_Add BPs.
