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

Change 3809757 by Jon.Nabozny

	Fixup BuildPhysx to only set up HTML5 when needed.

Change 3812325 by Jake.Leonard

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

	#Jira UE-53579

Change 3828032 by Jon.Nabozny

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

Change 3837391 by John.Barrett

	NetcodeUnitTest updates for better CIS/automation support.

Change 3837392 by John.Barrett

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

Change 3837397 by John.Barrett

	Moved a unit test to the 'Obsolete' folder.

Change 3837476 by John.Barrett

	Reduced unwanted OSS-null logspam.

Change 3844506 by Jake.Leonard

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

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

Change 3844803 by Jake.Leonard

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

	Please see Jira for recent comments

	#Jira UE-24791

Change 3844829 by Jake.Leonard

	Does the following:

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

	#Jira UE-53066,UE-54177

Change 3851997 by Jake.Leonard

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

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

	#Jira: UE-53763

Change 3882307 by John.Barrett

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

Change 3882311 by John.Barrett

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

	This is important for protecting against DoS attacks.

Change 3894785 by Jake.Leonard

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

	#Jira UE-54488

Change 3902627 by Jake.Leonard

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

	#Jira UE-54483

Change 3902632 by Jake.Leonard

	Fix voice issues on seamless travel for NullOSS

	#Jira UE-54899

Change 3904775 by Jake.Leonard

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

	#Jira UE-54488

Change 3968022 by Ryan.Gerleve

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


Change 3994505 by Jake.Leonard

	Fix some shootergame minor bugs:

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

	#Jira none

Change 3999511 by Jake.Leonard

	FArchive serializer for FUniqueNetIdSteam

	#Jira none

Change 4014550 by Jake.Leonard

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

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

	#Jira UE-55183

Change 4017165 by Jake.Leonard

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

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

	#Jira UE-53533

Change 4017215 by Jake.Leonard

	Fix MULTIHOME returning the incorrect ip address on Linux and Android

	#Jira UE-57463

	Convert FRepState in object replicator to a shared pointer

	#jira none

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

Change 4024131 by Ryan.Gerleve

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

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

	#jira nojira

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

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

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

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

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

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

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

	UNetDriver::GetFunctionRepLayout exposed as ENGINE_API for RepDriver use.

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

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

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

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

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

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

	Made UNetDriver::IsLevelInitializedForActor public.

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

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

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

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

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

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

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

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

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

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

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

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

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

	#jira none

	#AUTOMERGE using branch FNMain->DevNetworking of change#3919218 by ryan.gerleve on 2018/03/01 18:50:11.

Change 4024213 by Ryan.Gerleve

	UDemoNetDriver now properly associates actor channel close bunches with the actor's level. Fixes ensures & asserts that were occurring during replay playback due to trying to handle these channel closes while the level was streamed out.
	Moved the check for IsRecording in the ConditionallyCreatePacketManager functions to an if, since the check can now be triggered while the demo net driver is shutting down.

	#jira FORT-71916

	#AUTOMERGE using branch FNMain->DevNetworking of change#3919321 by ryan.gerleve on 2018/03/01 19:26:43.

Change 4024217 by Ryan.Gerleve

	Fix for placed actors not respawning in some cases when scrubbing in a replay: don't add startup actors that are destroyed due to level streaming out to a replay checkpoint's destroyed actor list. Added some verbose (off by default) logging to help detect these cases.

	#jira FORT-73939

	#AUTOMERGE using branch FNMain->DevNetworking of change#3923164 by ryan.gerleve on 2018/03/03 11:19:37.

Change 4024310 by Ryan.Gerleve

	Replication Graph:

	* Fix issue with dormancy node not fully reseting when spatialization grid is rebuilt
	* Improved some logging when failures do happen
	* Added Net.RepGraph.Spatial.BiasCreep cvar to force spatial rebuild every frame
	* Added blacklist of classes that can never cause a spatial rebuild.
	* Fixed issue with dynamic actors changing cull distances dynamically.
	* Removed unused rep graph node.

	GameplayDebugger support for ReplicationGraph. AGameplayDebuggerCategoryReplicator will start replicating once a replication owner is set on it.

	#jira none

	#AUTOMERGE using branch FortniteMainEngine_to_DevNetworkingEngine of change#3949584 by David.Ratti on 2018/03/16 08:36:01.

Change 4024394 by Ryan.Gerleve

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

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

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

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

	#AUTOMERGE using branch FortniteMainEngine_to_DevNetworkingEngine of change#3952558 by David.Ratti on 2018/03/19 09:19:09.

	#AUTOMERGE using branch FortniteMainEngine_to_DevNetworkingEngine of change#3959632 by david.ratti on 2018/03/22 12:51:19.

Change 4024398 by Ryan.Gerleve

	Fix for dormant actors not opening actor channel for multicast rpcs in some cases. Use the global cull distance rather than the per-connection which is cleaered for dormancy trickle.

	#jira FORT-76101

Change 4024403 by Ryan.Gerleve

	More robust fix for rep graph having multiple channels for the same actor open simulataneously. Guarded behind CVar_RepGraph_FixDuplicateChannels.
	Add a replication driver hook for UActorChannel::CleanUp.
	Don't replicate actors or RPCs if the channel is closing.
	Don't clear the channel pointer on FConnectionReplicationActorInfo as soon as the channel closes, but wait until it's cleaned up to either clear the channel if the actor's dormant or remove the actor info from the map completely otherwise.
	Fixed missing include in ReplicationGraphDebugging.

	#AUTOMERGE using branch FortniteMainEngine_to_DevNetworkingEngine of change#3975732 by ryan.gerleve on 2018/03/30 16:03:25.

Change 4024415 by Ryan.Gerleve

	Fix potential actor channel churning by making sure the close frame num is never lowered. This could happen for short-lived dependant actors.

	Removed CVar_RepGraph_FixDuplicateChannels: we definitely need this behavior to always be on.

	#AUTOMERGE using branch FortniteMainEngine_to_DevNetworkingEngine of change#3980479 by david.ratti on 2018/04/03 08:25:53.

Change 4024424 by Ryan.Gerleve

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

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

Change 3810363 by Mark.Satterthwaite

	More random fixes to mtlpp: most important is the extension to Buffer that allows creation of sub-buffers that are merely views onto a sub-range of the parent. These sub-buffers are valid to use throughout the mtlpp API with two exceptions: they may not be used for visibilityResultsBuffers and Set*BufferOffset functions cannot take this offset into account (as the encoder does not hold onto the buffers and I don't want it to). In the case of Set*BufferOffset the caller has to know what is going on and in the case of visibilityResultsBuffers it'll just assert as it isn't sensible.

	This makes it *much* easier to do things like sub-buffer allocation, though the caller must be aware of the alignment restrictions of their intended usage as they are not possible to enforce. For example, a call to SetVertexBuffer requires an offset alignment must match the alignment of the data-type in the shader for "device" resources, or for "constant" data it must be max(4, sizeof(datatype)) on iOS and 256 on macOS. This should allow for much more tightly packed sub-allocations than earlier approaches, though older drivers (e.g. Mac OS X 10.11) enforce only the coarser "constant" data restriction everywhere.

	rd_route v1.1.1 with attached TPS approval.

	For macOS function interposition which is useful for debugging and the occasional workaround.

Change 3845164 by Mark.Satterthwaite

	Add LLM support for macOS, including tracking of memory allocated in Objective-C. This makes use of runtime method swizzling in the Objective-C runtime and the rd_route library I added for Richard Wallis, which allows for arbitrary runtime function interposition and allows me to hook the custom allocators used in Apple's many Objective-C frameworks on which the whole macOS edifice is built. Objective-C objects are charged to the calling scope as they are too common to impose their own without murdering frame rate.

	We would need a TPS approval for an iOS function interposition library for this to work fully on iOS, if desired in the short term discarding LowLevelFree events that aren't in the map rather than asserting will workaround the problem.

	Duplicate #3831616

	Fix the black ground scattering on Metal - we've had issues with the atmospheric fog calculations for a long time - one or more intermediate operations generates different precision on Metal so we end up passing -ve values into sqrt which then generates NaN/INF. For Metal when compiling this file and this file only #define sqrt() to sqrt(abs()) so that we don't see anymore unexpected black in atmospheric rendering. This is far from ideal but I don't want to make abs all inputs into every sqrt because AFAIK this is the only case where we have an issue, and until we to investigate each intermediate calculation that isn't ridiculously, soul-crushingly tedious, it isn't practical to identify the source of the error.

	-Tweakables and utilities are now exposed through a Blueprint Function Library (rather than direct manipulation of console variables)
	-The Ansel photography session UI now exposes some engine effect tweakables as sliders. For example, if the game is using depth-of-field then sliders are made available to allow the photographer to change the focal depth etc. The developer may suppress this behavior through the Blueprint Function Library.
	-Letterboxing is now removed during multi-part capture, d'oh.
	-Tiled shots are taken at full resolution even if ScreenPercentage < 100
	-SSR is enabled during super-resolution shots since Ansel is now better at hiding any ensuing artifacts
	-Postprocess settings are frozen at session start to avoid discontinuities during photography, i.e. wandering between postprocess volumes when the camera auto-moves for stereo and 360 shots.

Change 3891925 by Yuriy.ODonnell

	Fix/workaround for inconsistent preprocessor definitions for NVAftermath that result in FD3D11DynamicRHI class layout mismatch. NVAftermath support is now enabled by default for Win64.

	NVAftermath is declared as a private dependency in D3D11RHI. It does not automatically propagate to modules that explicitly include private RHI headers (OculusHMD, OSVR, OSVRInput). This results in NV_AFTERMATH being defined while compiling RHI module and not defined when compiling other modules, causing memory corruption at runtime.

	The long-term solution for this and similar issues requires some mechanism for adding transitive module dependencies, so that anyone that depends on D3D11RHI module would automatically also get the NVAftermath. Additionally, private headers should *never* be included directly by external modules.

	The short-term solution is to explicitly add NVAftermath dependency to OculusHMD, OSVR and OSVRInput.

	Additionally, NV_AFTERMATH is no longer forced by D3D11RHIPrivate.h when it's not defined. This allows catching this kind of mismatch in the future through a compiler warning (C4668).

	[Integrate] Scene Textures uniform buffer
	* Base Pass Uniform Buffer now contains a Scene Textures uniform buffer.  Previously the translucent base pass had to check ~40 loose scene texture parameters every draw.
	* FMeshMaterialShader's must now bind PassUniformBuffer and supply a valid pass uniform buffer.  For most passes this is just FSceneTextureUniformParameters.
	* FRendererModule::DrawTileMesh can now cleanly set dummy scene texture resources, just by configuring how the pass uniform buffer is created.
	* Moved scene texture shader functions out of Common, into SceneTexturesCommon which must be manually included by shaders that want to use them
	* Separate Mobile Scene Textures uniform buffer to silo the platform complexities

	Moved DBuffer inputs out of FDeferredPixelShaderParameters and into FOpaqueBasePassUniformParameters

	Removed per-frame material uniform expressions.  GameTime material node with period is now implemented with an fmod in the shader, without the use of MaterialFloat, so that it will happen at full precision.
	* Per-frame expressions were used when the GameTime material node had a period, to do the fmod on the CPU where 32 bit precision is guaranteed, for mobile GPU's where pixel shader precision is sometimes less than 32fp.

	Moved forward shading data into the Base Pass Uniform Buffer
	Removed instanced stereo support for the light cull grid - will have to be reimplemented without changing SRV's per draw
	Base pass sets View Uniform Buffer from DrawRenderState instead of choosing which one to set per-draw

These are used when rendering thumbnails of a material in a different domain, which could be opaque, but the opaque base pass drawing policy does not bind a scene textures uniform buffer, so the shader must not bind it.
	* Opaque materials can no longer use EyeAdaptation.

	Fix for black flickering on first paint with weighted material landscape on Mac.  When using AsyncCopyFromBufferToTexture in Metal we put the blit operation on the prologue encoder - however after a draw call using that resource the copy operation should happen after on the current encoder, this keeps the correct order of operations.

	Initial implementation of tracing profiler to show CPU and multiple GPUs on the same timeline. Currently only supported on DX12 platforms.

	Use `TracingProfiler frames=N` console command to trigger a capture of the next N frames. Trace is saved to disk as a JSON file into `Saved/Profiling/Traces` directory.
	Trace file uses Google Tracing format and can be visualized in Chrome built-in profiler (chrome://tracing).

	`r.GPUStatsChildTimesIncluded=1` CVar makes timing scopes hierarchical.
	`TracingProfiler.BufferSize=N` CVar controls the size of the tracing buffer, which may need to be increased for long traces (default is 65k events). Only can be set at startup.

	Ensure that packed globals are reuploaded when the command-encoder is restarted - don't simply invalidate the existing parameters. This properly handles cases where a single logical render-pass is broken into multiple command-encoders and/or command-buffers - otherwise all shaders must reset all parameters each time. When we move between frames we *do* want to perform a full state reset though as previous frame globals are treated as invalid.

Change 3990080 by Mark.Satterthwaite

	Change the way we invalidate the visibility buffer between command-buffers and command-encoders so that on iOS you can reuse the same buffer within the same command-buffer, but not across more than one. The code provides an exception to this rule when running under the MetalRHI validation tools which can break each draw call into its own buffer.

	1. Thumbnail manager called SetStaticMesh(nullptr), which added StaticMeshComponent to deferred render updates.
	2. UStaticMesh::Build called FStaticMeshComponentRecreateRenderStateContext and destroyed DenderData, but didn't touch Thumbnail's manager StaticMeshComponent as it was nullptr.

Change 4007682 by Richard.Wallis

	No video when playing HLS streaming video on Mac.  2 Issues, FPS was zero making duration for video sample buffer nonsense and Video Track dimensions were going to zero on the AVAsset once fully initialized when playing HSL streams.  Now cache relevant details and handle zero frame rate.

	Notes:
	- Caching the frame rate is not as important as we could look it up each time and fix for zero - ignoring that at the moment.
	- Assume we DO NOT want the FrameSize to be the last fetched video frame size from the AvfMediaVideoSampler as I think that is the video quality for streaming video and not the media frame size.
	- Renamed a variable in the AvfMediaVideoSample - was called FrameRate but it was the FrameDuration by that point.

Change 4018251 by Mark.Satterthwaite

	Fix broken rendering on Metal that tracked back to the innocuous looking changes in CL #4006495 (no blame attached - these changes are entirely reasonable) and cause various bugs in QAGame's TM-DistanceFields, ElementalDemo and probably more. Doesn't fix broken SpeedTree rendering :(.

	MetalRHI was allowing uniform buffers to blow away linear texture buffers when the constant buffer has been elided due to dead-code elimination. This problem can manifest without linear textures if the uniform buffer contains both constant data and a resource-table but the shader doesn't use any of the constant data. That's because Metal doesn't separate constant buffers from any other kind of buffer unlike D3D which separates all the slots out - and Metal doesn't provide enough buffers to emulate the D3D arrangement. So far this has only manifested in the MVF + Linear Texture case but a more robust solution will be necessary long term.

Change 4025337 by Yuriy.ODonnell

	Improved use-after-free detection mechanism and physical memory usage of MallocStomp on Windows.

	MallocStomp on Windows will now reserve virtual address space for every allocation and then commit physical pages only to the valid usable part.
	Physical pages will be unmapped on Free, but virtual address space will not be released and therefore will never be re-used.

	Virtual address space is allocated from the OS in blocks of 1GB and then linearly sub-allocated.
	This reduces VA space usage, as VirtualAlloc returns blocks on 64KB granularity even if we just need 4KB. As a small bonus, this also reduces number of syscalls per allocation.

	This dramatically increases accuracy of use-after-free detection, but consumes significant amount of memory for the OS page table.
	Virtual memory limit for a process on Win10 is 128 TB, which means we can afford to keep virtual memory reserved for a long time.
	Running Infiltrator demo consumes ~700MB of virtual address space per second.

	Additionally, committing physical pages only for the usable part of the entire virtual block reduces physical memory usage by ~30% compared to old behavior,
	which allocated and committed entire block of pages via BinnedAllocFromOS and then marks border page as non-accessible.

Change 4030225 by Yuriy.ODonnell

	Static analysis warning fix: make sure declaration of Sleep() is consistent between Windows headers and TBB

	The complexity with this particular case is that the warning is generated in synchapi.h, which is included by some Windows headers.
	If a module includes TBB and then Windows platform headers, static analyzer will report this warning.
	Suppressing it would require wrapping all instances of Windows header includes in third-party macros.

	Current pragmatic solution is to modify the Sleep() declaration in TBB header to be consistent with Windows and to report the issue to Intel for a permanent fix.

	Fixed UStaticMeshComponent modifying its UStaticMesh when undoing a change.  This caused a crash when other static mesh components using the same mesh asset were rendered, since their rendering state was not recreated.  A component should not modify its asset during PostEditUndo.
	 * This behavior has been present for a long time but was previously hidden because only the vertex factory of the mesh asset is cached in static draw lists, not any of its rendering resources (eg vertex declaration).

	Projects targetting OpengGL don't have access to compressed formats (as the implementation has texture tiling issues).
	Add "r.AllowVolumeTextureAssetCreation" set as 0 by default, which controls whether volume texture can be sampled in materials and whether they can be created from 2D texture assets.

	[Integrate] Pass Uniform Buffers
	* All pass-constant shader inputs should go into the appropriate pass uniform buffer, instead of being set per-draw
	* Moved many per-draw base pass parameters over to the Base Pass Uniform Buffer
	* Opaque and Translucent base pass shaders have different uniform buffers, which allows compile errors when accessing an invalid resource (eg GBuffer in Opaque), instead of silently falling back to GBlackTexture

	Uniform buffers can now contain nested structs with UNIFORM_MEMBER_STRUCT()
	* This allows composing a uniform buffer at a particular update frequency out of many features, with encapsulation of each feature's parameters in a struct.
	* Eg deferred fog uses FFogUniformParameters, but so does translucency in the base pass, where FFogUniformParameters is reused nested inside the base pass uniform buffer.
	* Resources can now be located anywhere in the uniform buffer.  Padding is inserted to the cbuffer representation to keep memory layouts matching.  In the future the cbuffer could be compacted.
	* RemoveUniformBuffersFromSource() which works around HLSLCC lack of struct initializers now handles nested structs

Change 3979171 by Mark.Satterthwaite

	Copying //Tasks/UE4/Dev-UERNDR-354-mtlpp to Dev-Rendering (//UE4/Dev-Rendering):

	Rewrites MetalRHI in terms of mtlpp, which is a C++ wrapper library built around Metal's Objective-C API that attempts to reduce overheads and eliminate resource lifetime errors.

	Regarding mtlpp:
	- The mtlpp library uses C++ constructor/destructor and smart-pointer style management of Objective-C retain/release calls to prevent over- and under-release problems.
	- To reduce Objective-C overheads the mtlpp library caches the internal C-function that implements the Objective-C selectors for the most commonly used Metal protocol types and calls the function directly - this avoids objc_msgSend which does this look-up dynamically and thus improves CPU performance slightly.
	- Another advantage is that mtlpp provides infrastructure to extend the Metal API slightly to help improve MetalRHI - the two important aspects are mtlpp::CommandBufferFence which provides a consistent CPU<->GPU synchronisation primitive and sub-buffer allocations from mtlpp::Buffer which allow for far superior memory management.
	- Validation functionality is also provided by mtlpp to detect CPU vs. GPU data races and resource lifetime validation - this is expensive and is thus optional and compiled out from Shipping binaries that should be used when performance is most critical. The validation only works between resource modification and *submitted* command-buffers - anything that is being actively encoded on the CPU is ignored and it remains the responsibility of the application to validate the order of operations when encoding.

	Apple Platform:
	- LLM support which tracks Objective-C objects is enabled only on macOS - we don't have the necessary libraries to intercept and override the internal system calls on iOS.

	MetalRHI:
	- All the types are switched over, (mostly) insuling the external API from the horror of Metal and Objective-C.
	- Buffers are now managed quite differently, small buffers are allocated from a magazine allocator that allocates in fixed blocks from a larger parent buffer, intermediate sized buffers are allocated from a simple heap allocator that wraps a larger buffer and anything of reasonable size (>2Mb) will use the pooled allocator. This *radically* reduces the number of buffer resources, by as much as a factor of 10, because they are now sub-allocated without the need to use MTLHeap or MTLFence so they are performance equivalent to the existing implementation on the GPU and much faster on the CPU. Total memory use is approximately the same.
	- Vertex & index buffer management has been updated to reflect changes in the management and to avoid reallocating buffers which provide a Linear Texture (for SRVs) unless strictly necessary. This ensures that even in cases where a dynamic buffer is updated multiple times in a frame it will still work acceptably well.
	- The Metal ring-buffer implementation is completely different again, this time it can use Managed memory on macOS which allows for much better performance on eGPUs which will be more and more important for Mac.
	- Everyone that needs to wait on a command-buffer fence (rather than a command-buffer itself) now use mtlpp::CommandBufferFence, which prevents race conditions between the different command-buffer handlers (which sometimes execute out of order).
	- LLM tracking should now report the same data as the MetalRHI stats group for buffer & texture allocations - there is no segmentation for Vertex/index/Structured/Uniform allocations in Metal so these numbers are going to be wrong and will need to be rethought.
	- What will be unseen are the number of small but important resource usage fixes that avoid stale resources from being bound to the device after the point at which they become invalid. This should eliminate a class of errors where the GPU uses a resource pointer that is modified by the CPU and was necessary to satisfy the new mtlpp validation code.

	Other:
	- Remove the Metal focused workarounds from the ClothBuffer resource binding and related vertex-buffer SRV - these were put in when MetalRHI/MetalShaderFormat couldn't handle float->uint conversions correctly and they should now.
	- Fix a validation error caused by trying to render a 0-sized scissor rect which is invalid in Metal and simply pointless elsewhere.
	- Consistency of disabling the Manual Vertex Fetch behaviour in shaders.

Change 3864588 by Graeme.Thornton

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

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

Change 3874457 by Ben.Marsh

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

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

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

	#jira UE-54611

Change 3889547 by Ben.Marsh

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

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

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

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

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

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

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

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

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

Change 3896366 by Ben.Marsh

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

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

Change 3896367 by Ben.Marsh

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

Change 3896425 by Ben.Marsh

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

Change 3896461 by Ben.Marsh

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

	[//UE4/Main/Samples/Games/ShooterGame/ShooterGame.uproject]

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

Change 3901301 by Ben.Marsh

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

Change 3904648 by Ben.Marsh

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

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

	Put data for CrashReportClient in a PAK file of its own (under Engine/Programs/CrashReportClient/Content/Paks/CrashReportClient.pak). There are a large number of small files required for it to run with loose files, which takes a lot of space on disk (due to cluster sizes), and is unweildy to move around.

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

Change 3921002 by Ben.Marsh

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

Change 3921008 by Ben.Marsh

	UGS: Prevent pause waiting for mutual exclusivity when syncing precompiled binaries. We don't need to generate project files or build, so there's no need to wait in line.

Change 3924604 by Graeme.Thornton

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

Change 3924638 by Graeme.Thornton

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

Change 3942404 by Graeme.Thornton

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

Change 3942825 by Ben.Marsh

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

Change 3947359 by Graeme.Thornton

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

Change 3947360 by Graeme.Thornton

Change 3954694 by Ben.Marsh

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

	To define a Macro, use the syntax:

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

	To expand a macro, use the syntax:

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

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

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

	This removes the only remaining use of FModuleManager::GetCleanModuleFilename(), which is also now removed.

	#jira UE-52405

Change 3969346 by Steve.Robb

	Missed some bad FScript(Map/Set)Helper usage from CL# 3698969.

Change 3969598 by Ben.Marsh

	Fix warning from VS2017.

Change 3971101 by Graeme.Thornton

	TBA: Added RoundTrip mode to TextAsset commandlet which does a sequence of saves and checks for determinism. It will do 3 binary saves, 3 text saves, then 3 alternate binary->text saves.

Change 3971407 by Ben.Marsh

	UBT: Fix exception when enumerating toolchains if the directory does not exist yet.

Change 3971523 by Graeme.Thornton

	Make compressed block offsets in a pak file store offsets relative to the file header, rather than absolute. Reduces the amount of entropy when data changes in the pak file, making it play nicely with patching

Change 3971613 by Ben.Marsh

	Fix Lightmass non-unity compile errors.

Change 3971649 by Ben.Marsh

	Disable optimization around FTickerObjectBase constructor on Win32 due to ICE.

Change 3971829 by Ben.Marsh

	Fix deprecated header warning from PVS Studio.

Change 3972503 by Ben.Marsh

	Changes to build failure notifications:

	* Only people that submitted between builds with different error messages will be included on emails by default.
	* Email subject line will be different for each failing build step, but will include the CL of the first failing step. This will result in one thread for each build failure (a success email is sent with the same subject line).
	* Anyone that starts a build will be included on all failure emails.

Change 3972732 by Ben.Marsh

	Changes to ensure notification messages are stable.

Change 3972810 by Ben.Marsh

	Write debug information about the digest computed for a change, to assist with debugging it if it's not stable.

Change 3973331 by Ben.Marsh

	Fix missing dependency on linker response file. Prevents target being relinked when build environment changes.

Change 3973343 by Ben.Marsh

	Made sure that lazy object pointers are only fixed up for PIE in actual PIE worlds.

Change 3975336 by Robert.Manuszewski

	CIS fix after the last merge from main

Change 3976999 by Ben.Marsh

	Move the Windows stack size settings onto the WindowsTargetRules object, and add the [RequiresUniqueBuildEnvironment] attribute to ensure it's not overwritten incorrectly.

	This should cause CIS to better errors for compiling Odin editor.

Change 3977934 by Ben.Marsh

	UBT: Allow setting additional compiler/linker arguments through properties on the TargetRules object.

Change 3977953 by Ben.Marsh

	UBT: Enumerate all Visual Studio 2017 install locations using the Visual Studio Setup interop SDK. Multiple simultaneous Visual Studio installations are now supported, and using registry keys to determine installation directories has been deprecated. Allows choosing toolchains from preview versions as well as full versions.

Change 3978544 by Ben.Marsh

	UBT: Include verbose timing information from compiler frontend if using VS2017 15.7 preview 2 or later.

Change 3978780 by Ben.Marsh

	Add Visual C++ 2017 redist files to AppLocalDependencies, and update the prereq installer to include 2017 support DLLs.

Change 3980890 by Ben.Marsh

	UBT: Update project file generator to support VS2017 solution options file; fixes C# projects being opened by default when generating new project files.

Change 3981495 by Ben.Marsh

	Do not include embedded interop assemblies in the list of references required by a C# project; they are not required build products.

	#jira UE-54343

Change 3982157 by Ben.Marsh

	Only output a warning message if BuildConfiguration.xml schema validation fails; we may have settings that only apply to code in another branch.

Change 3982239 by Ben.Marsh

	Update tooltip directing users to install Visual Studio 2017 instead of 2015.

Change 3983395 by Graeme.Thornton

	Backwards compatibility for pak files with compressed chunk offsets

Change 3983769 by Ben.Marsh

	UAT: Allow using PDBCOPY.EXE installed as part of the Windows 10 SDK to strip symbols, and add a better message if it can't be found.

Change 3984529 by Ben.Marsh

	BuildGraph: When run with the -Preprocess=... argument, no steps will be executed.

Change 3984557 by Ben.Marsh

	BuildGraph: Return the updated patterns from FilePattern.CreateMapping(), so we can print accurate messages when displaying the source and target directories for a copy or move task.

Change 3986520 by Ben.Marsh

	Remove hacks to uniquify response file name on Android and Linux.

Change 3987166 by Steve.Robb

	Allow overloading of functions which take TFunctions or TFunctionRefs with mutually exclusive signatures.

Change 3989061 by Graeme.Thornton

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

Change 3989109 by Graeme.Thornton

	TBA: TextAsset commandlet emits a warning when binary package determinism fails

Change 3990823 by Ben.Marsh

	UGS: Allow project settings to specify a client path rather than a filesystem path. Not currently usable through UI.

Change 3990832 by Ben.Marsh

	Fix for 4096 char limit on FParse::Value.

Change 3992222 by Steve.Robb

	Advice added to the coding standard for using default member initializers.

Change 3993675 by Ben.Marsh

	UGS: Add UI to allow creating new workspaces and selecting projects from existing workspaces that are not currently synced.

Change 3994199 by Ben.Marsh

	UGS: Fix child processes being unable to spawn other child processes with the CREATE_BREAKAWAY_FROM_JOB flag, to add them to their own job objects.

	In Windows 7 or earlier job objects cannot be nested, so child processes have to create separate job objects and spawn processes with CREATE_BREAKAWAY_FROM_JOB to be able to add them. This fails unless parent process' job object was created with JOB_OBJECT_LIMIT_BREAKAWAY_OK.

	Discussed here: https://msdn.microsoft.com/en-us/library/windows/desktop/hh448388(v=vs.85).aspx

Change 3994243 by Ben.Marsh

	UGS: Use the select stream dialog instead of displaying a drop list unless there's a stream filter specified. We have way too many streams for this to be useful in a menu unless it's filtered.

Change 3994260 by Ben.Marsh

	UGS: Tweak the stream filter dialog to only use the previous selected node if the filter terms match. It may be a parent node of something that matches, even though it doesn't match itself.

Change 3994350 by Ben.Marsh

	UGS: Automatically guess the correct root path for new workspaces based on the most common existing workspaces for the current user.

Change 3995159 by Ben.Marsh

	UGS: Do not delete files which are outside the sync filter. People expect to be able to sync different projects within a stream without having to update sync filters.

	Indend to re-introduce this functionality through the manual 'clean workspace' operation.

Change 3995169 by Ben.Marsh

	UGS: Show options as dimmed in the open project dialog, if the radio button for those controls is not checked. Automatically set the radio button if the focus is given to one of those controls.

Change 3995228 by Ben.Marsh

	UGS: Update recently opened projects list when editing project for an existing tab.

Change 3995312 by Ben.Marsh

	UGS: Stop showing all dialogs in the taskbar.

Change 3995929 by Robert.Manuszewski

	Completely rewritten FReferenceChainSearch class used by 'obj refs' command.

	- 3+ times faster
	- Uses the same code as GC to track all the references down
	- Actually reports all reference chains properly
	- Less code that is more readable than the previous version

Change 3995981 by Ben.Marsh

	UGS: Clean workspace window will now force-sync files that have been deleted or which are writable.

Change 3996113 by Ben.Marsh

	UGS: Fix crash upgrading config files from older versions.

Change 3997990 by Ben.Marsh

	UGS: Prevent error when syncing an empty workspace.

Change 3998095 by Ben.Marsh

	UGS: Change logic for dealing with job objects: rather than creating breakaway jobs (requires co-operation with spawning process), always try to use nested job objects (requires Windows 8.1+). If it fails, ignore the error if we're already part of a job.

	Also forcibly terminate the process on dispose to handle cases where the job object wasn't created.

Change 3998264 by Ben.Marsh

	UGS: Fix exception when switching projects in-place.

Change 3998643 by Ben.Marsh

	Fix shared DDC not being used for installed engine builds.

	#jira UE-57631

Change 4000266 by Ben.Marsh

	UnrealPak: Add an option that allows rebuilding a set of PAK files with different settings. Usage is:

	    UnrealPak [PakFile] -Repack [-Output=FileOrDirectory] [Options]

	The input pak file may be a single file or wildcard, and is overwritten unless the -Output parameter is specified.

Change 4000293 by Ben.Marsh

	Add a compression flag that allows selecting compressor without using the default platform implementation.

Change 4000315 by Ben.Marsh

	Add support for custom compressors implemented via modular features. Specify -compressor=<PathToDll> on the command line to UnrealPak to load a compressor from an external DLL.

Change 4000610 by Ben.Marsh

	UnrealPak: Add a parameter for compression block size (-compressionblocksize=XXX). Accepts arguments with MB/KB suffixes, as well as byte counts.

Change 4000627 by Ben.Marsh

	UBT: Include enabled plugin info in the UBT log.

Change 4000793 by Ben.Marsh

	UBT: Remove some member variables from VCEnvironment that don't need to be stored.

Change 4000909 by Ben.Marsh

	UBT: Add VS2017 installations to the list of paths checked for MSBuild installations.

Change 4001923 by Ben.Marsh

	UBT: Allow any plugins which are enabled by default to be included in the enabled list, even if they don't have any modules for the current platform. This changes the build-time logic to match the runtime logic.

	At some point in the future we may add a separate SupportedHostPlatforms list to each plugin to do this explicitly, rather than guessing via the per-module whitelist.

Change 4001927 by Ben.Marsh

	Fixes for compiling against the Windows 10 SDK.

Change 4002439 by Robert.Manuszewski

	Added TDefaultReferenceCollector and FSimpleReferenceProcessorBase to extract common code for clients of  TFastReferenceCollector

Change 4005516 by Ben.Marsh

	UBT: Add warnings whenever a module adds an include path or library path that doesn't exist

Change 4006168 by Ben.Marsh

	CIS fixes.

Change 4007458 by Ben.Marsh

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

Change 4009343 by Ben.Marsh

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

Change 4009501 by Ben.Marsh

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

Change 4009509 by Ben.Marsh

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

Change 4010543 by Ben.Marsh

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

Change 4010553 by Ben.Marsh

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

Change 4012030 by Ben.Marsh

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

	UBT: Suppress toolchain output when generating project files.

Change 4023248 by Ben.Marsh

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

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

Change 4025759 by Ben.Marsh

	Fix universal CRT include paths not being added to compile environment for VS2015.

Change 4026002 by Ben.Marsh

	UBT: Check the old registry locations for the Windows SDK installation directory.

Change 4026068 by Ben.Marsh

	UBT: Use the correct compiler version in the error message for not having the UCRT.

Change 4026181 by Ben.Marsh

	Fix DebugGame editor configurations not enumerating modules correctly.

	#jira UE-58153

Change 4026285 by Ben.Marsh

	UBT: Add additional logging for enumerating Windows SDKs.

Change 4026708 by Ben.Marsh

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

Change 4029404 by Ben.Marsh

Change 4032288 by Ben.Marsh

	Remove UFE from the BuildEditorAndTools script.

Change 3833533 by Ben.Marsh

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

Change 3838569 by Steve.Robb

	Algo moved up a folder.

Change 3848581 by Robert.Manuszewski

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

	#jira UE-49446

Change 3864743 by Steve.Robb

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

	#jira UE-54612

Change 3865020 by Graeme.Thornton

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

Change 3869550 by Josh.Engebretson

	New SymGen and SymUpload tasks (ShooterGame usage example)
	Example C# symbolicator (using saved crash and data router formats)

	USE_TUPLE_AUTO_RETURN_TYPES moved to PLATFORM_COMPILER_HAS_DECLTYPE_AUTO.

Change 3910012 by Ben.Marsh

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

Change 3920044 by Graeme.Thornton

	TBA: Text asset loading

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

Change 3921587 by Steve.Robb

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

	#jira UE-55681

Change 3942873 by Ben.Marsh

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

Change 3944629 by Graeme.Thornton

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

Change 3945381 by Ben.Marsh

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

Change 3968969 by Steve.Robb

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

Change 3969417 by Ben.Marsh

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

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

Change 3972443 by Ben.Marsh

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

Change 3977198 by Ben.Marsh

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

Change 3979632 by Ben.Marsh

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

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

Change 3981738 by Ben.Marsh

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

Change 3983888 by Steve.Robb

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

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

Change 3984019 by Steve.Robb

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

Change 3985502 by Steve.Robb

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

Change 3985999 by Graeme.Thornton

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

Change 3986461 by Ben.Marsh

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

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

Change 3990081 by Ben.Marsh

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

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

Change 3996714 by Chad.Garyet

	UGSRestAPI, conversion of UGS to use it.

	#jira none

Change 4008287 by Ben.Marsh

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

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

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

Change 4008516 by Chad.Garyet

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

	#jira none

Change 4010296 by Chad.Garyet

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

Change 4024045 by Ben.Marsh

	Set the list of supported target platforms for OnlineSubsystemGameCircle.

	#jira UE-57887

Change 4031014 by Ben.Marsh

Change 3835044 by Aaron.Carlisle

	Exposure for asset_import_data (editor property) and it's functions: extract_filenames and get_first_filename.

Change 3835466 by Patrick.Boutot

	Hide function from Python that need special compile command to be executed by the VM.

Change 3839237 by Jamie.Dale

	Added a way to inspect the full chain of properties that are currently being serialized by an archive

	You used to only have access to the leaf-most property, and while you could use its outer chain to inspect other properties within the same object/struct, you couldn't always get the full chain (eg, if you had an object containing a struct).

Change 3839974 by Jamie.Dale

	Make sure that SerializedProperty is copied correctly, as SetSerializedPropertyChain may set it to something else

Change 3842311 by Jamie.Dale

	Fixing potential null level assert

Change 3842313 by Jamie.Dale

	Updated settings editor to handle external properties

Change 3842316 by Jamie.Dale

	Allowing a console command to be given to GEditor/GEngine even if there's a player

	CL# 1848982 said it was to prevent multiple execution of stat commands, however that no longer seems to be an issue.

Change 3842867 by Jamie.Dale

	Added a way to generate diffs from editor transactions

	The notifications from these diffs are send to UObject::PostTransacted and FCoreUObjectDelegates::OnObjectTransacted.

	These notifications are typically generated when a transaction is "finalized", but can also be generated from "snapshots" (eg, to trap nodes being dragged in the world). They're also generated from normal undo/redo events.

Change 3844428 by Patrick.Boutot

	Move the SetMaterial code from the StaticMeshEditor to StaticMesh to be reusable by script.

Change 3845966 by Jamie.Dale

	Added support for minimal game RPC worlds

	These can be created in the editor and engine and exist to allow RPC communication via Unreal Networking in a way that is sandboxed from any other worlds that may be loaded (like the main game world)

Change 3848844 by Patrick.Boutot

	Expose EComponentMobility to blueprint.

Change 3854616 by Patrick.Boutot

	Add Custom way time step the engine loop. Will be used by the Synchronization of media for enterprise.

Change 3867158 by JeanMichel.Dignard

	UBT
	- Added the ability for dll programs to export symbols.

	#jira UEENT-541

Change 3872342 by Jamie.Dale

	Merging static analysis fixes from 4.19

Change 3879305 by Jamie.Dale

	Improved the processing of py files from exec commands

	The old logic used to just test if the entire command was a .py file. The new logic extracts out the first token and sees if that's a .py file, and if it is, treats the remaining data as extra arguments.

Change 3879306 by Jamie.Dale

	Added a minimal commandlet for invoking Python scripts

Change 3881631 by Jamie.Dale

	Added basic RTTI to Python meta-data types

Change 3885384 by Jamie.Dale

	[Python] Prevent glue code using reserved names

Change 3888957 by Patrick.Boutot

	In MediaPlayer, only create a PlayerFacade & Playlist when it's not a ClassDefaultObject.
	The MediaPlayerFacade is a MediaTickable. That trigger the tick thread to be awake even if there is no Media playing.

Change 3888961 by Patrick.Boutot

	Fix FInterval::IsValid return type.

Change 3888980 by Patrick.Boutot

	Modification to Media and MediaAsset to support MediaSmith. The TInterval<int64> will be changed into TTinterval<FTimespan> UEENT-947. MediaSampleQueue's critical section will be change into an atomic operation UEENT-948.

Change 3889165 by Patrick.Boutot

	Fix build. Missing include for Timespan. Introduce with CL 3888980.

Change 3889261 by Jamie.Dale

	[Python] Fixing some more name conflicts in generated code

Change 3889504 by Darren.Pegg

	Add option to change PreferredPixelFormat

Change 3891193 by Patrick.Boutot

	Fix build. Missing include for Interval. Introduce with CL 3888980.

Change 3897108 by Patrick.Boutot

	TTinterval use it own traits. Create a Interval traits for Timespan.
	#jira UEENT-947

Change 3899669 by Jamie.Dale

	Fixed Functions sometimes being exposed to Python as if they were Structs

Change 3900692 by Jamie.Dale

	Removed some boilerplate associated with wrapping a basic type to Python

	You can now derive from TPyWrapperBasic to wrap a type that is simply a value copied into Python (see FPyWrapperName and FPyWrapperText for an example)

Change 3901066 by conan.reis

	UE4 editor script bindings (Cobra) and helper functions for version control
	- exposed SourceControl class with common source control methods and associated SourceControlState structure
	- commands have smart file strings that can convert from any of fully qualified path, relative path, long package name, asset path or export text path (often stored on clipboard)
	- commands store any errors in a shared error text object which is optionally printed to the error log
	- renamed some calls across the UE4 codebase to USourceControlHelpers::CheckOutOrAddFile() from USourceControlHelpers::CheckOutFile()
	- included Python test script for source control commands including that auto-creates test files as needed and passes various types of files to test as command line arguments. Any unexpected results displays error messages.

Change 3901388 by Jamie.Dale

	Minimal Slate hooks for Python

Change 3901456 by Jamie.Dale

	Added missing file

Change 3901549 by Jamie.Dale

	Removing some more Windows defines that were causing build issues

Change 3904518 by conan.reis

	Source Control
	- ensured that "check if modified" flag is set whenver getting source control state in USourceControlHelpers::QueryFileState() which was needed when using Perforce source control provider

Change 3905612 by Francis.Hurteau

	Optimize RemoveDuplicates somewhat using a TSet
	#jira UEENT-217

Change 3912626 by Jamie.Dale

	Fixed ShouldExcludeDerivedClasses option not working

	RecursiveClassesExclusionSet requires a base ClassNames entry to operate on when filtering.

Change 3917739 by Jamie.Dale

	Output Log suggestions list is now clamped to the work area width of the monitor that hosts the widget

Change 3917744 by Jamie.Dale

	Changed generated code to reference the UProperty and UFunction directly, rather than constantly look them up by name

	Names were originally used because UHT couldn't access the objects when it registered the glue code, but now that we generate at runtime via reflection, we already have the relevant objects available, and caching them the glue structs helps performance at both generation time and runtime.

Change 3918832 by Jamie.Dale

	Removed field iteration from Python function calls

	We now cache the input and output parameters for all function calls (methods, get/set, and delegates) and use this rather than iterate the struct fields.

Change 3920648 by Patrick.Boutot

	Remove the bottom right part of the windows border of the grabbed frame when in the editor. Tested in the standalone, windowed and full screen.
	Add option to request a FlushOnDraw on the viewport. Flushing in SDI output flow decreases the performance by ~10ms. SDI output is synchronized and the engine tick follows that synchronization.

Change 3921396 by Jamie.Dale

	Split up the generated type data to correspond to the type being wrapped

	A lot of types can just use the minimal set, but classes and structs have some extra data.

Change 3921619 by conan.reis

	- add delegate to FSourceControlWindows::ChoosePackagesToCheckin() that gives info for result, result description, files added, files checked in and flag indicating whether files were checked out again.
	- also added result info to FSourceControlWindows::PromptForCheckin()

	#jira UE-55255

Change 3921624 by conan.reis

	Removed Source Control common files from pre compiled header
	- main changes are in UnrealEdPrivatePCH.h, UnrealEdSharedPCH.h, SouceControlWindows.h and the added SouceControlWindows.cpp
	- remaining files have includes changed to accomodate

Change 3921958 by conan.reis

	Fix attempt for incude file dependency needed by some build configurations (likely PCH disabled) caused by CL3921619

Change 3922740 by conan.reis

	Included SourceControlOperations.h and SourceControlHelpers.h back in ISourceControlProvider.h though it does not need them since other files that were including ISourceControlProvider.h have come to expect their inclusion.
	They were previously removed in CL3921624

Change 3923375 by Jamie.Dale

	Added optimized FString <-> icu::UnicodeString conversion for platforms using UTF-16 native strings

Change 3926547 by Jamie.Dale

	Added support for struct method "hoisting"

	This allows you to tag a helper function that takes a struct as its first argument with the ScriptMethod meta-data (optionally providing a new name) to "hoist" that helper function to be a method of the struct it operates on when wrapped for Python.

Change 3927050 by conan.reis

	Source control - ensured that  ISourceControlProvider::Execute(FConnect, EConcurrency, FSourceControlOperationComplete) delegate is called on initial connection even if it fails immediately. Modified Perforce, Git and Subversion source control providers

	#JIRA UE-55256

Change 3929268 by conan.reis

	- fixed case in Perforce source control code where the server available flag was set even when the server was not successfully connected
	- removed Perforce error message about file folders outside of the workspace client mappings
	- clarified comments for ISourceControlProvider::IsEnabled() and ISourceControlModule::IsEnabled()

	#JIRA UE-55254

Change 3931024 by Rex.Hill

	Expose FBX and Texture import to python

Change 3931273 by Rex.Hill

	Hide re-import slate notification pop-up during python automated asset import

Change 3931368 by Jamie.Dale

	Stopped bools coercing to numeric types in Python nativization

Change 3931374 by Jamie.Dale

	Added support for struct math operator "hoisting"

	This allows you to tag a helper function that takes a struct as its first argument with the ScriptMathOp meta-data (providing a potentially semi-colon separated list of operators to map to) to "hoist" that helper function to be a math operator of the struct it operates on when wrapped for Python.

Change 3932586 by Rex.Hill

	Removed file read into unused memory buffer during Fbx import

Change 3934308 by Jamie.Dale

	Added a public interface for the Python plugin

	Very basic, just lets you query if Python is compiled in, and lets you execute Python commands like you would via the Output Log.

Change 3935088 by conan.reis

	- Added info/warning and error message storage to all the source control operation structures so additional information can be made available.
	- Added ISourceControlOperation::GetResultInfo() which returns the modified control structures (mentioned above) with appended info/warning messages and error messages and implemented its use in all source control operations in Perforce, Git and Subversion.

	#JIRA UE-55257

Change 3936668 by Rex.Hill

	#jira UE-55985
	Avoid re-allocation of memory buffer holding file bytes during asset import

Change 3940596 by Rex.Hill

	#jira UE-55989 Optimize skeletal mesh import performance scaling

	Overlapping vertex check was O (N^2)
	100k vertex mesh took ~15 seconds to perform overlap step now takes 0.023 seconds

Change 3942629 by Rex.Hill

	#jira UE-55995 Read fbx file only once during import

	Fixes a memory leak of FbxScene and reduces wait time during import.

Change 3942884 by Rex.Hill

	Python asset import can now customize destination asset name

Change 3946278 by Jamie.Dale

	Added stricter conversion for math operator arguments

	PyConversion now returns FPyConversionResult rather than bool, which will tell you not only whether a conversion succeeded or failed, but also whether type coercion was applied during the conversion.

	This allows the operator stack evaluation to run a first pass looking for an exact argument match, before falling back to a coerced match if available. This allows operators to apply correctly to coerced types (eg, int vs float overloads).

Change 3948455 by Jamie.Dale

	Added generic Tick function to FPythonScriptPlugin

	This can also handle init logic for after the engine is fully initialized

Change 3948888 by Jamie.Dale

	Added settings for the Python plugin

	You can now define start-up scripts to execute once the engine is initialized, additional system paths for Python, and whether you want to enable developer mode (which will enable things like deprecation warnings).

Change 3948982 by Jamie.Dale

	Fixed Python 3 build error caused by CObject being removed in Python 3.2

Change 3949614 by Francis.Hurteau

	Create a camera cut track from the camera switcher camera index animation curve when importing a fbx in sequencer
	#jira UEENT-1053

	Update error message to be more specific when ENGINE_API keyword is found before 'static' keyword for a UFUNCTION

Change 3953452 by Jamie.Dale

	Fixed some dependencies

Change 3953645 by Jamie.Dale

	Fixed Python parameter packing treating bool output paramers as potential return values

	void GetState(bool& OutState) would have previously triggered the code for packing output for a function that returns a bool.

Change 3953850 by Jamie.Dale

	Fixed doc string generation for a function with multiple output paramters and no return value

Change 3954279 by Jamie.Dale

	Initial support for exposing deprecated properties and functions to Python

	This handles properties and functions that are directly deprecated. We still need to handle the cases where they're renamed and a redirector is left.

Change 3954922 by Rex.Hill

	Expose UnloadPackages to python

Change 3955209 by Jamie.Dale

	Initial support for exposing deprecated classes to Python

Change 3955248 by Jamie.Dale

	unreal.load_module("modulename")

Change 3955561 by Rex.Hill

	Expose asset export to python

Change 3956068 by Rex.Hill

	Linux compile fix.

Change 3960449 by Rex.Hill

	Fix automated test using bCombineMeshes

Change 3960495 by Patrick.Boutot

	Add a temporary menu to show the MetaData of an asset.
	The menu will need to be updated to have a look and feel of the Detail View and support edition at one point.

Change 3961599 by Rex.Hill

	Reduced peak memory during import of meshes related to duplicate vertex tracking

Change 3962104 by Rex.Hill

Change 3967014 by Jamie.Dale

	Added a way to get the CDO in Python

	Wrapped objects now have a get_default_object class method

Change 3967151 by Jamie.Dale

	Added stats to track Python generation time

Change 3968006 by Simon.Therriault

	Media Samples

	- Removed Locks and Min/Max SampleTime from queues
	- Added methods to fetch NextSampleTime and SampleCount in queues
	- Added MediaSource base class for players that want to be time synchronized

	#jira UEENT-948

Change 3969119 by Patrick.Boutot

	Add delay functionnality to MediaPlayer to delay the frame by some time. It will allow more than one player to be start at the same time, played at the same frame but offset in relation to each other.

	Updating 4.19 credit list
	#jira none

Change 3941865 by Mark.Satterthwaite

	Fix the incorrect landscape rendering and the incorrect render-to-texture from blueprint bugs with MetalRHI.

	- Track outstanding AsyncCopyBufferFromBufferToBuffer operations to identify attempts to modify overlapping ranges within the same prologue command-buffer. This doesn't work and requires that we break the current render-pass and issue on the current command-buffer. A log warning will be emitted  when this occurs.

	- Don't attempt to alias private memory buffers the moment they are released from the RHI resource because that can lead to incorrect sharing of the memory when used by AsyncCopyBufferFromBufferToBuffer.

	#jira UE-56021

Change 3940993 by Marc.Audy

	Do not return the last column if the specified column does not exist.
	Allow display names to be used when looking for a property if the table is backed by a user defined struct.
	Do not crash if a property with the given name is not found.

	#jira UE-56017

Change 3939179 by Ben.Marsh

	#jira UE-55987

Change 3938345 by Peter.Sauerbrei

	fix to Icons not being built on Mac
	#jira UE-53492

Change 3938305 by Mark.Satterthwaite

	For whatever reason moving the buffer initialisation into the prologue command buffer doesn't work - this make absolutely no sense to me. I suspect that this is *merely* moving a render pass boundary around somewhere and forcing raster-state to be reapplied.

	#jira UE-56005

Change 3937968 by Ben.Marsh

	Disable the boot DDC if we're not in the editor. Fixes access violations when multiple SCW instances attempt to read/write to the same file.

Change 3934982 by Marc.Audy

	Fix shadow variable issue

	#jira UE-55957

Change 3934892 by Mark.Satterthwaite

	In MetalRHI treat BUF_Volatile buffers as Shared or Managed memory in all circumstances so that multiple updates within a render pass are respected even though this will hurt CPU performance. This fixes GPU particles on macOS. Also push initialisation upload into the async. command buffer to avoid it overwriting a later Lock/Unlock! Only read-back and copy-buffer operations should be on the 'current' command buffer as they need to be inline with all outstanding commands.

	#jira UE-55956

Change 3934421 by Arciel.Rekman

	#jira UE-55885 Fix corruption of packages when starting and then cancelling an async load of a package that already exists, or attempting to async load a script package
	It now keeps track of which packages were created by the async load system and will only throw those away on cancel

	Fixing material editor resetting background to off
	#jira UE-55267

Change 3920519 by Phillip.Kavan

	Fix a regression in which elements would not be initialized when constructing the value assignment for UDS-typed container members in nativized Blueprint C++ code.

	Change summary:
	- Modified FEmitDefaultValueHelper::InnerGenerate() to remove UDS from the list of special cases that avoid calling InitializeStruct() as part of new element construction. Previously the conversion code assumed the compiler would perform value initialization of a nameless temporary, but that is no longer valid in 4.19, as UDS types have been changed to function more like native structs, and as such all converted UDS types will now emit an explicit default ctor which is now used to assign defaults that differ from the zero-initialized value.

	#jira UE-55628

Change 3920476 by Michael.Trepka

	Clean up Mac menu item cache at exit before SlateApplication is fully destroyed.

	#jira UE-55599

	Moving over:
	"HLOD: Building HLOD for P map with sublevels requires HLODSetupAsset when it should not
	#fix Ensure that we dynamically add HLOD level treeview items whenever they are required, rather than adding a static number of levels according to the worldsettings"

	#jira UE-55619

Change 3920126 by Max.Preussner

	MediaCompositing: Implemented media track for Sequencer

	Copied from Dev-Sequencer

	#jira UE-53974

Change 3920004 by Jack.Porter

	Disable Manual Vertex Fetch SRV creation when MVF is disabled.

	Made a single RHISupportsManualVertexFetch(EShaderPlatform) to control whether to use MVF. The Shader Platform (or alternatively, feature level) is the only thing that can decide whether or not to use MVF because we need to know when we compile the shaders if we're going to do MVF or not. Checking GSupportsResourceView at runtime is useless because the shaders can't change and so if GSupportsResourceView can ever be false for a platform, the shaders need to have been built without it.

	Can't add C++ code to Enterprise projects (when enterprise is installed)

	Root cause: When compiling a C++ project, Datasmith modules are included in the build process (with the wrong path)

	Fix:
	- Added two more Enterprise directories, Plugins and Intermediate, to the Enterprise directories to check against
	- Build the correct path for the Datasmith modules and plugins in FindOrCreateModuleByName. Added check to see if module is under one of the Enterprise directories.
	- Added modules to list of precompiled modeules in UEBuildTargets.AddPrecompiledModules if Engine and Enterprise are 'installed and the module is under Enterprise.

	#jira UEENT-1032

Change 3915240 by Ben.Marsh

	Reduce editor startup times by ~15s on Windows.

	Platform loading code recursively scans every module for dependent DLL modules to load first. Change to make it early-out as soon as it encounters a module which is already in memory (via a call to GetModuleHandle() from ResolveMissingLibraryImportsRecursive). Also use a TSet<> to store set of visited modules rather than an Array.

	Now spends <0.1s total in this function on editor startup.

	(Change looks larger than it is due to moving functions out of WindowsPlatformProcess.h to avoid introducing TSet dependency into this header).

Change 3914599 by Andrew.Rodham

	Sequencer: Sequence template source signatures are now also compared to catch the case where a sub-sequence asset has been saved but not modified

	  - The following sequence of events exposes this issue:
	    - Create a master sequence with a single shot that spawns a cube
	    - Add this sequence to a level and set it to auto-play
	    - Save everything and restart
	    - Resave just the inner shot asset without opening it
	    - PIE
	    - The inner shot never spawns its cube because its template was wiped on save, but its signature never changed. Since the master sequence previously didn't check the template source signature, it ends up trying to evaluate an empty template.

	[CONSOLE] [^] Added RHI Command List Enqueue Lambda method (merging as edit CL 3879722 from //Fortnite/Main to //UE4/Release-4.19)

	 - Can be used to enqueue arbitrary tasks on the RHI thread from the render thread (similar to how EURC works for GT -> RT tasks), without having to write lots of bolierplate FRHICommand functor classes.
	 - The first overload of EnqueueLambda method will check Bypass() to determine if it should run the lambda immediately or defer to the RHI thread.
	 - This can be overriden via the 2nd overload if you need to check additional things such as IsRunningRHIInSeparateThread.
	 - The function returns true if the lambda was enqueued and deferred to the RHI thread, otherwise false. This can be used to optionally add RHIThreadFences for unlock commands etc.

	Fix/workaround for inconsistent preprocessor definitions for NVAftermath that result in FD3D11DynamicRHI class layout mismatch. NVAftermath support is now enabled by default for Win64.

	NVAftermath is declared as a private dependency in D3D11RHI. It does not automatically propagate to modules that explicitly include private RHI headers (OculusHMD, OSVR, OSVRInput). This results in NV_AFTERMATH being defined while compiling RHI module and not defined when compiling other modules, causing memory corruption at runtime.

	The long-term solution for this and similar issues requires some mechanism for adding transitive module dependencies, so that anyone that depends on D3D11RHI module would automatically also get the NVAftermath. Additionally, private headers should *never* be included directly by external modules.

	The short-term solution is to explicitly add NVAftermath dependency to OculusHMD, OSVR and OSVRInput.

	Additionally, NV_AFTERMATH is no longer forced by D3D11RHIPrivate.h when it's not defined. This allows catching this kind of mismatch in the future through a compiler warning (C4668).

	Sequencer: Fixed overlapping ranges being inserted into the evaluation field during compilation

	  - The issue was that track segments that had been combined with adjacent segments (due to them being identical) would potentially cause a subsequently compiled frame to overlap with a range that had already been inserted into the evaluation field.
	  - The insertion code previously asserted that only minor overlaps were catered for (due to fp rounding errors) and assumed that a supplied range could not entirely contain any other range in the field.
	  - The solution is to supply the insertion time along with the range to know exactly where the data should live in the field, and crop the range to the maximum allowable space between adjacent ranges.

	Duplicate CL #3871025
	Make Manual Vertex Fetch a property of the shader platform for Metal - only the desktop platforms (METAL SM5/SM5_NoTess/MRT) will use manual vertex fetch. The mobile platforms use vertex descriptors. 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.

	Fix tessellation shaders in Metal with Manual Vertex Fetch enabled:
	- The control points idnex buffer shouldn't collide with anything else.
	- We can't use the optimisation of loading texture width & height from the buffer meta-table in tessellation shaders as the combined stages don't guarantee not to clobber unused buffer slots and screw it up when we use linear textures.

	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
	* tracking of Texture and mesh allocation on Windows D3D11 & D3D12

	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

	[CONSOLE] [~] Enable XGE shader compilation by default.
	 - Also set XGE mode to "force interception". With XGE on by default, we don't want people with an old Incredibuild version using the old system inadvertently.

Change 3726554 by Luke.Thatcher

	[CONSOLE] [+] Improved Scoped Named Events
	 - Added SCOPED_NAMED_EVENT(_FSTRING/_TEXT/_F) macros to allow use of string literals, FString and printf in scoped named event strings.
	 - Replaced explicit use of FPlatformMisc::Begin/EndNamedEvent throughout the engine with macros, so the events can be compiled out.
	 - Fixed performance issues on various platforms with named events. SCOPED_NAMED_EVENT macros were not considering whether the platform uses wide or ansi char strings.

	Duplicate from FN CL 3712515
	CSV profiler GPU and pre-declared stat support
	- refactor the GPU profiler so it's no longer dependent on the stats system and can work in Test builds
	- add support for pre-declared CSV stats, using FNames (these are required for GPU stats)
	- 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
	- Reduced memory overhead for timestamps through bit-packing (now 16 bytes per marker instead of 24), and splitting stats into different types

Change 3814041 by Ben.Woodhouse

	Integrate as edit CL 3796390 from Fortnite/Main:

	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

	Disable CSV unit stats on the dedicated server

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 3817582 by Ben.Woodhouse

	Fix android compile warning

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
	Fix an issue where the csvprofile console commands would sometimes result in an empty CSV. The root cause was GFrameNumber incrementing between the console command being read and FCSVProfiler::EndFrame(). We now use our own frame counter which is updated in EndFrame, so this can't happen

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

	D3D12 RHI: only refcount uniform buffers if GRHINeedsExtraDeletionLatency is false, which is no longer the case for PC.

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

Change 3805828 by Gil.Gribb

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

Change 3806784 by Ben.Marsh

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

Change 3807549 by Graeme.Thornton

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

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


Change 3822594 by Ben.Marsh

	UAT: Improvements to log file handling.

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

Change 3823695 by Ben.Marsh

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

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

Change 3823845 by Ben.Marsh

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

Change 3824180 by Ben.Marsh

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

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

	#jira UE-53813

Change 3829189 by Ben.Marsh

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

Change 3830444 by Steve.Robb

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

Change 3830718 by Ben.Marsh

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

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

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

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

	#jira UE-53845

Change 3831064 by Ben.Marsh

	Fix log file contention when spawning UBT recursively.

Change 3832654 by Ben.Marsh

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

Change 3832680 by Ben.Marsh

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

Change 3832695 by Ben.Marsh

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

Change 3833528 by Ben.Marsh

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

Change 3833543 by Ben.Marsh

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

Change 3834354 by Robert.Manuszewski

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

	#jira UE-52035

Change 3834400 by Robert.Manuszewski

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

	#jira UE-52035

Change 3834947 by Steve.Robb

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

Change 3835004 by Ben.Marsh

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

Change 3835340 by Ben.Marsh

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

Change 3835972 by Ben.Marsh

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

Change 3836019 by Ben.Marsh

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

Change 3836269 by Ben.Marsh

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

Change 3836543 by Ben.Marsh

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

Change 3836546 by Ben.Marsh

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


Change 3836805 by Ben.Marsh

	Fix commandlet to compile marketplace plugins.

Change 3836829 by Ben.Marsh

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

Change 3837036 by Ben.Marsh

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

Change 3837037 by Ben.Marsh

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

Change 3837040 by Ben.Marsh

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

Change 3837247 by Ben.Marsh

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

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

Change 3837262 by Ben.Marsh

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

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

Change 3837343 by Ben.Marsh

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

Change 3837356 by Ben.Marsh

	Fix invalid character encodings.

Change 3837727 by Graeme.Thornton

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

Change 3837823 by Ben.Marsh

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

Change 3837831 by Graeme.Thornton

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

Change 3837857 by Robert.Manuszewski

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


Change 3837943 by Robert.Manuszewski

	PR #4405: Fix FGarbageCollectionTracer (Contributed by mhutch)


Change 3838451 by Ben.Marsh

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

	#jira UE-53996

Change 3839519 by Ben.Marsh

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

Change 3843790 by Graeme.Thornton

	UnrealPak: Log the size of all encrypted data

Change 3844258 by Ben.Marsh

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

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

	#jira UE-54157

Change 3845796 by Ben.Marsh

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

Change 3845823 by Ben.Marsh

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

	#jira UE-54123

Change 3845901 by Arciel.Rekman

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

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

	(Edigrating 3819174 to Dev-Core)

Change 3846439 by Ben.Marsh

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

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

Change 3816608 by Ben.Marsh

	UBT: Use DirectoryReference objects for all include paths.

Change 3816954 by Ben.Marsh

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

Change 3816986 by Ben.Marsh

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

Change 3816991 by Ben.Marsh

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

Change 3823090 by Ben.Marsh

	UAT: Improve logging for child UAT instances.

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

Change 3826082 by Ben.Marsh

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

Change 3827025 by Ben.Marsh

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

Change 3829927 by James.Hopkin

	Made HTTP interface const correct

Change 3833533 by Ben.Marsh

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

Change 3835826 by Ben.Marsh

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

Change 3835969 by Ben.Marsh

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

Change 3837777 by Steve.Robb

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

Change 3838569 by Steve.Robb

	Algo moved up a folder.

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

	#jira UE-51472

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

Change 3718782 by Steve.Robb

	Stats TSAN fixes.
	Optimizations to FCycleCounter::Start() to only read the stat name once.

Change 3735000 by Robert.Manuszewski

	Always preload the AssetRegistry module on startup. even if EDL is disabled.

	Even without EDL, if the async loading thread is enabled the AssetRegistryModule will otherwise be loaded from the ASL thread and that will assert.

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 3755672 by Graeme.Thornton

	Updating ShooterGame with new CryptoKeys based security setup

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...). The slot number is used to define the workspace name that should be used.

Change 3758498 by Ben.Marsh

	Re-throw exceptions when a file cannot be deleted when cleaning a target.

Change 3758921 by Steve.Robb

	ThreadSanitizer fix to FThreadSafeStaticStatBase::HighPerformanceEnable to do a relaxed atomic load on access.

Change 3760642 by Steve.Robb

	ThreadSanitizer fix for concurrent access to GMainThreadBlockedOnRenderThread.

Change 3760669 by Graeme.Thornton

	Improvement to OpenSSL based signing key generator. Generate a full RSA key then steal the primes from it, rather than generating the primes manually.

Change 3763358 by Graeme.Thornton

	Ensure that all branches within FGenericPlatformMisc::RootDir() produce an absolute path with no duplicate slashes
	Remove relative->abs conversion of root dir from FPaths::MakeStandardFilename(), now that we know RootDir() always returns an absolute path

	Derived from the content of this PR:
	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.

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.

	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().

	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.

	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.

	* 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).

	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.

	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.

	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.
