Change 3059740 on 2016/07/21 by Ben.Marsh

	Format license violations on separate lines rather than as a single multi-line string, so they can be parsed out correctly by the EC log parser.

Change 3063115 on 2016/07/25 by Ben.Marsh

	Add missing projects to Mono AutomationTool solution.

Change 3067125 on 2016/07/27 by Ben.Marsh

	Clean up and document the engine versioning system.

	* Version.h has a summary of all the different versioning concepts in UE4, as well as an explanation of what all the macros do.
	* VersionLocked.h has been removed. ENGINE_NET_VERSION and ENGINE_REPLAY_VERSION can be overriden directly in Version.h if necessary.
	* Added explicit macros for ENGINE_CURRENT_CL_VERSION And ENGINE_COMPATIBLE_CL_VERSION. The MODULE_API_VERSION macro is now defined to be the same as ENGINE_COMPATIBLE_CL_VERSION.
	* Build/Build.version now includes the compatible CL version, so it can be determined without having to parse header files inside MacToolChain.cs.
	* UpdateLocalVersion UAT command now exposes a -CompatibleCL=... argument to update ENGINE_COMPATIBLE_CL_VERSION and the CompatibleChange property in Build.version.
	* SetVersion BuildGraph task now has a CompatibleChange="" attribute to update ENGINE_COMPATIBLE_CL_VERSION and the CompatibleChange property in Build.version.
	* VersionFileUpdater now makes an effort to parse tokens matching the macros it's going to overwrite, rather than requiring exact matches in whitespace in Version.h.
	* Running UpdateLocalVersion now syncs files to revision 0 before writing if P4 is enabled, similarly to UGS, or fails if they are not writable.

Change 3067242 on 2016/07/27 by Ben.Marsh

	Fix UGS showing a build failure/warning dialog immediately if you submit while the build is yellow/red. Now ignores builds before your last submitted CL.

Change 3068116 on 2016/07/28 by Ben.Marsh

	Add a small Windows utility to terminate all running processes under a given root directory, and run it before and after every sync. Mean to fix instances where zombie editor processes do not terminate correctly and cause subsequent syncs to fail.

Change 3068246 on 2016/07/28 by Ben.Marsh

	UGS: Improvements to 'Clean Workspace' dialog - empty folders are now set to be deleted by default, and added a context menu to select all/none/empty/default for a subtree, as well as to open Windows explorer at that location.

Change 3068573 on 2016/07/28 by Ben.Marsh

	Attempt to fix AppDomain unload errors; suspect caused by delay to terminate child processes when managed exception is thrown on child threads. Now waits for the currently running threads to finish executing before quitting.

Change 3068575 on 2016/07/28 by Ben.Marsh

	Respect the -noxge command-line argument when compiling UHT.

Change 3068665 on 2016/07/28 by Ben.Marsh

	Delete any DLLs in output folders which share names with build products. The Windows loader reads DLLs from the first location it finds a file with a matching name, so we need to ensure that it doesn't load stale DLLs when output directories are changed (moving a module into a plugin, for example).

Change 3073316 on 2016/08/02 by Ben.Marsh

	CoreUObject: Replace header guards with #pragma once directives.

Change 3073325 on 2016/08/02 by Ben.Marsh

	CoreUObject: Manually untangle a few circular includes around ObjectBase.h and Class.h to allow making them into IWYU-style headers.

Change 3074391 on 2016/08/02 by Ben.Marsh

	GitHub #2646: Always allow programs to build as part of non-game solution configurations.

Change 3075123 on 2016/08/03 by Richard.Fawcett

	Ensure that zip files created outside of Ionic Zip can be unzipped with CommandUtils.UnzipFiles

	Zip files created with 7-zip, WinRAR, and Windows Explorer all contain entities for directories, not just the files in them.  Code in CommandUtils.UnzipFiles made the assumption that all entities in the zip file were files, and an exception was being thrown on encountering a directory.

Change 3075848 on 2016/08/03 by Ben.Marsh

	UBT: Fix a few cases where it's possible to construct a non-canonical DirectoryReference - root directories on Windows must always have a terminating slash, but any other directories must note. DirectoryInfo and Path.GetFullPath() do not enforce this requirement.

Change 3075850 on 2016/08/03 by Ben.Marsh

	UBT: Fix UHT failures when running with -nopch.

Change 3077058 by Ben.Marsh

	UHT: Remove the auto-generated ObjectBase.h include from generated header files. Was originally added to allow doxygen to parse headers more easily, but was switched to parsing the file only as part of parent files instead.

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

Change 3836829 by Ben.Marsh

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

Change 3839519 by Ben.Marsh

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

Change 4042043 by Steve.Robb

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

Change 4042056 by Robert.Manuszewski

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

Change 4042104 by Robert.Manuszewski

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

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

Change 4042377 by Robert.Manuszewski

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

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

Change 4042427 by Robert.Manuszewski

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

Change 4042482 by Robert.Manuszewski

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

Change 4042635 by Robert.Manuszewski

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

Change 4044092 by Steve.Robb

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

Change 4044102 by Robert.Manuszewski

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

Change 4044113 by Steve.Robb

	Another Clang fix.

Change 4044160 by Robert.Manuszewski

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

Change 4044287 by Steve.Robb

	Typo fix.

Change 4047723 by Graeme.Thornton

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

Change 4048015 by Graeme.Thornton

	TBA: Weak/Soft/Lazy pointer serialization changes

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

Change 4048021 by Steve.Robb

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

Change 4048544 by Robert.Manuszewski

	Fixing ConditionalBeginDestroy profiling after changes to incremental CBD.

Change 4051028 by Graeme.Thornton

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

Change 4051056 by Graeme.Thornton

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

Change 4051111 by Graeme.Thornton

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

Change 4051154 by Graeme.Thornton

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

Change 4051181 by Graeme.Thornton

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

Change 4051197 by Graeme.Thornton

	TBA: ObjectProperty text serialization

Change 4051216 by Graeme.Thornton

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

Change 4051261 by Graeme.Thornton

	TBA: Convert UMetaData to structured archive

Change 4051374 by Steve.Robb

	Incorrect assert removed.

Change 4051562 by Robert.Manuszewski

	Adding stats for the new GC internal functions

Change 4051614 by Graeme.Thornton

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

Change 4052512 by Graeme.Thornton

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

Change 4053917 by Robert.Manuszewski

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

Change 4053919 by Robert.Manuszewski

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

Change 4055518 by Daniel.Lamb

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

	#jira nojira
	#test prefilght automated test.

Change 4056854 by Graeme.Thornton

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

Change 4056858 by Graeme.Thornton

	TBA: Updated USetProperty to proper structured archive usage

Change 4056872 by Graeme.Thornton

	TBA: Add map property field to test object

Change 4056873 by Graeme.Thornton

	TBA: Convert UMapProperty to full structured archive

Change 4056994 by Graeme.Thornton

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

Change 4059728 by Ben.Marsh

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

Change 4059805 by Graeme.Thornton

	Fixed typo in text serialization. Fixes CIS automation test errors

Change 4060007 by Graeme.Thornton

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

Change 4060092 by Stefan.Boberg

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

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

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

Change 4060108 by Stefan.Boberg

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

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

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

Change 4060143 by Graeme.Thornton

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

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

Change 4062432 by Ben.Marsh

	Fix error message when enumerating P4 changes.

Change 4062648 by Ben.Marsh

	Add missing p4 integration action.

Change 4063620 by Graeme.Thornton

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

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

Change 4066963 by Robert.Manuszewski

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

Change 4067133 by Robert.Manuszewski

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

Change 4067443 by Steve.Robb

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

Change 4068156 by Steve.Robb

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

Change 4070258 by Graeme.Thornton

	Fixes for VSCode

Change 4070372 by Graeme.Thornton

	TBA: Script struct serialization to structured archives

Change 4071913 by Ben.Marsh

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

Change 4071914 by Ben.Marsh

	Missing files.

Change 4071937 by Ben.Marsh

	Missing header.

Change 4072015 by Ben.Marsh

	Fixes for compiling PakFileUtilities as part of the editor.

Change 4072826 by Steve.Robb

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

Change 4073271 by Daniel.Lamb

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

	#test none

Change 4074708 by James.Hopkin

	#core Removed redundant Casts

Change 4074763 by Steve.Robb

	Fix for TSparseArray::Reserve() size.

Change 4076063 by Ben.Marsh

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

Change 4077064 by Robert.Manuszewski

	Fixing compile error in PakFileUtilities

Change 4077144 by Graeme.Thornton

	TBA: TextAssetCommandlet improvements

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

Change 4077412 by Ben.Marsh

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

Change 4077760 by Graeme.Thornton

	TBA: Loading fixed for tagged property serialization

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

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

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

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

Change 4078800 by Ben.Marsh

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

Change 4079745 by Graeme.Thornton

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

Change 4079847 by Graeme.Thornton

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

Change 4079925 by Ben.Marsh

	Fix incorrect assignment when deriving name for chunked pak file.

Change 4080214 by Ben.Marsh

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

Change 4082394 by Graeme.Thornton

	CIS fix for variable shadowing warning

Change 4082583 by Ben.Marsh

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

Change 4082652 by Ben.Marsh

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

Change 4082755 by Graeme.Thornton

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

Change 4082756 by Graeme.Thornton

	Fixed some incorrect documentation for pakfile compressed chunk headers

Change 4082883 by Graeme.Thornton

	Static analysis warning fix

Change 4082912 by Ben.Marsh

	Move ExceptionUtils into DotNETUtilities.

Change 4085291 by Graeme.Thornton

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

Change 4085523 by Graeme.Thornton

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

Change 4086037 by Robert.Manuszewski

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

Change 4088655 by Graeme.Thornton

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

Change 4091474 by Steve.Robb

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

Change 4093632 by Steve.Robb

	CIS fixes.

Change 4093656 by Graeme.Thornton

	Build fix

Change 4093744 by Ben.Marsh

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

Change 4099712 by Gil.Gribb

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

	#jira UE-59686

Change 4099912 by Stefan.Boberg

	Cooking timer optimizations:

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

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

Change 4100519 by Stefan.Boberg

	Quick fix for Linux build issue introduced in 4099927

Change 4105327 by Stefan.Boberg

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

	Fixes check when using -FullLoadAndSave to cook

Change 4105448 by Stefan.Boberg

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

Change 4109031 by Ben.Marsh

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

Change 4109588 by Ben.Marsh

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

Change 4109595 by Ben.Marsh

	Missing project file for DotNETUtilities.

Change 4110724 by Stefan.Boberg

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

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

Change 4111304 by Ben.Marsh

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

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

Change 4112708 by Steve.Robb

	Fix for TBitArray::MaxBits in assignment.

Change 4114133 by Stefan.Boberg

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

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

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

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

Change 4115010 by Robert.Manuszewski

	Fixing CIS

Change 4115249 by Robert.Manuszewski

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

	#jira UE-56267

Change 4117091 by Ben.Marsh

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

Change 4117207 by Ben.Marsh

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

Change 4119175 by Ben.Marsh

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

Change 4119987 by Ben.Marsh

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

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

Change 4119991 by Ben.Marsh

	Update version number for UGS launcher to 1.13.

Change 4121943 by Robert.Manuszewski

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

Change 4122592 by Steve.Robb

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

Change 4122819 by Stefan.Boberg

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

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

Change 4122872 by Stefan.Boberg

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

Change 4123109 by Stefan.Boberg

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

Change 4123455 by Ben.Marsh

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


Change 4124207 by Ben.Marsh

	UBT: Remove some unnecessary indirection for generated code paths.

Change 4124217 by Ben.Marsh

	UBT: Remove another unused variable from UEBuildModuleCPP.

Change 4124377 by Stefan.Boberg

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

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

Change 4125071 by Stefan.Boberg

	Some tweaks to FQueuedThreadPoolBase scheduling and memory management

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

Change 4126132 by Ben.Marsh

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

Change 4126867 by Graeme.Thornton

	TBA: Fix tagged binary formatter

Change 4127010 by Robert.Manuszewski

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

Change 4127932 by Ben.Marsh

Change 4133681 by Ben.Marsh

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

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

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

	Example:

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

Change 4190082 by Ben.Marsh

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

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

	Add support for UnrealPak plugins.

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

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

Change 4223318 by Ben.Marsh

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

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

Change 4223401 by Ben.Marsh

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

Change 4223899 by Ben.Marsh

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

Change 4224637 by Ben.Marsh

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

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

Change 4224710 by Ben.Marsh

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

Change 4229817 by Ben.Marsh

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

	Add the Delete command to Perforce wrapper in DotNETUtilities.

Change 4234688 by Ben.Marsh

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

Change 4234711 by Ben.Marsh

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

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

	#jira UE-62545

Change 4261831 by Ben.Marsh

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

Change 4266019 by Josh.Adams

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

Change 4266264 by Ben.Marsh

	Remove override for the __IPHONE_OS_VERSION_MIN_REQUIRED macro on TVOS.

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

	#jira UE-62578

Change 4266273 by Ben.Marsh

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

Change 4266614 by Graeme.Thornton

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

Change 4266763 by Ben.Marsh

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

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

	#jira UE-62600

Change 4268558 by Robert.Manuszewski

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

	Allow mirroring Oodle files to remote Mac.

Change 4074774 by Steve.Robb

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

Change 4082591 by Ben.Marsh

	Move the Log class from UBT to DotNetUtilities.

Change 4091456 by Steve.Robb

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

Change 4156437 by Ben.Marsh

	Lots and lots of fixes compiling for Clang on Windows.

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

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

Change 4157389 by Ben.Marsh

	Few more fixes for compiling the editor with Clang.

Change 4183911 by Ben.Marsh

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

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

Change 4184311 by Ben.Marsh

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

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

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

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

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

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

Change 4200452 by Ben.Marsh

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

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

Change 4206189 by Ben.Marsh

	UBT: Simplify logic for precompiling binaries.

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

Change 4215466 by Ben.Marsh

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

Change 4215975 by Ben.Marsh

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

Change 4220154 by Ben.Marsh

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

Change 4224708 by Ben.Marsh

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

Change 4224958 by Ben.Marsh

	Remove CoreMinimal.h includes from Core.

Change 4229059 by Ben.Marsh

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

Change 4230508 by Ben.Marsh

	Fixup precompiled header setting for samples and games.

Change 4231457 by Ben.Marsh

	Fix exceptions in log messages having trailing newlines.

Change 4232406 by Ben.Marsh

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

Change 4234177 by Ben.Marsh

	Set up private PCH files everywhere that previously used them.

Change 4235973 by Ben.Marsh

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

Change 4238842 by Ben.Marsh

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

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

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

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

Change 4255042 by Ben.Marsh

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

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

Change 4260567 by Ben.Marsh

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