Change 2719147 on 2015/10/07 by Mark.Satterthwaite
Allow the shader cache to perform some precompilation synchronously on load before falling back to asynchronous compilation to balance load times against total time spent precompiling. Added a stat to the group that reports how long the precompile has been running until it completes so it is easier to track.
Change 2719182 on 2015/10/07 by Mark.Satterthwaite
Refactor the ShaderCache's internal data structures and change the way we handle recording whether a particular predraw state has been submitted to try and make it more efficient.
Change 2719185 on 2015/10/07 by Mark.Satterthwaite
Merging CL #2717701: Try and fix random crashes on Mac when manipulating bound-shader-states caused by ShaderCache potentially providing a bogus shader state pointer on exit from predraw.
Change 2719434 on 2015/10/07 by Mark.Satterthwaite
Make sure that Mac ensures reports have a source context and a sane callstack when sent to the crash-reports server.
Change 2724764 on 2015/10/12 by Josh.Adams
[Initial AppleTV support]
Merging //depot/YakBranch/... to //UE4/Dev-Platform/...

PS4 - Calc reserve size required for DMA copy when using unsafe command buffers
Change 2726401 on 2015/10/13 by Mark.Satterthwaite
Merging CL #2716418: Fix UE-15228 'Crash Report Client doesn't restart into project editor on Mac' by reporting the original command line supplied by LaunchMac, not the modified one that strips the project name. The CRC can then relaunch as expected.
#jira UE-15228
Change 2726421 on 2015/10/13 by Lee.Clark
PS4 - Don't try to clear invalid targets
Change 2727040 on 2015/10/13 by Michael.Trepka
Merging CL 2724777 - Fixed splash screen rendering for images with DPI different than 72
Change 2729783 on 2015/10/15 by Keith.Judge
Fix huge memory leak in Test/Shipping configurations, caused because I am a numpty.
Change 2729847 on 2015/10/15 by Mark.Satterthwaite
Merging CL #2729846: On OS X unconstrain windows from the dimension of the parent display when in Windowed mode - it is OK for them to be larger in this case. They do need to be repositioned if on the Primary display so that they don't creep under the menu bar and become unmovable/unclosable and Fullscreen windows still need to be constrained to a single display. We can now take screenshots of windows that are larger than the display & not get grey bars beyond the cutoff.
#jira UE-21992
Change 2729865 on 2015/10/15 by Keith.Judge
Fast semantics - Finish up resource transitions, adding resource decompression where appropriate and using non-fast clears where we can't determine the resource transition.
Change 2729897 on 2015/10/15 by Keith.Judge
Fast Semantics - Make sure all GetData() calls are made safe with GPU fences.
Change 2729972 on 2015/10/15 by Keith.Judge
Removed the last vestiges of ID3D11DeviceContext/ID3D11DeviceContext1 from the Xbox RHI. Everything now uses ID3D11DeviceContextX directly.
This should be marginally quicker as it stops a double call to ClearState().
Change 2731503 on 2015/10/16 by Keith.Judge
Added _XDK_VERSION to the DDC key for textures, which should solve the issue of the tiling mode changing in August XDK (and future changes Microsoft may inflict).
Change 2731596 on 2015/10/16 by Keith.Judge
Fast Semantics - Add deferred resource deletion queue to make deleted resources be actually deleted a number of frames later so that the GPU is definitely finished with them. Hooked up the temporary SRVs for dynamic VBs as a first step.

Change 2732018 on 2015/10/16 by Mark.Satterthwaite
Emit a shader code cache for each platforms requested shader formats, this is separate to the targeted formats as not all can or need to be cached.
- The implementation extends the ShaderCache's hooks in FShaderResource's serialisation function to capture the required shaders.
- Each target platform has its own list of cached shader formats, analogous to the list of targeted RHIs. Presently only the Mac implements this.
- Code cached shaders are now compressed (for size) to reduce the overhead associated with keeping all the shader code around - this works esp. well for text-based formats like GLSL.
Change 2732365 on 2015/10/16 by Josh.Adams
- Packaging a TVOS .ipa now works (still haven't tried any of the Editor integration like Launch On)
Change 2733170 on 2015/10/18 by Terence.Burns
Fix for Android IAP query not returning entire inventory.
Change 2733174 on 2015/10/18 by Terence.Burns
Fix Movie player issue where wait for movie to finish isnt being respected.
Seems a stray bUserCanceled event flag was causing this not to be observed.
Added some verbose logging to apple movie player.
Change 2733488 on 2015/10/19 by Mark.Satterthwaite
Added the ability to merge the .ushadercache files used by the ShaderCache to store shader & draw state information.
- Fixed a bug that would cause invalid shader membership and draw state information to be logged.
- Added a separate command-line tool to merge shader cache files, currently Mac-only but in theory should work on other platforms too.
Change 2735226 on 2015/10/20 by Mark.Satterthwaite
Fix temporal AA rendering on GL/Mac OS X - you can't rely on EyeAdaptation values unless SM5 is available so only perform that code on SM5 & we must correctly clamp saturate(NaN) to 0 as the current hlslcc won't do that for us (& is required by the HLSL spec). The latter used to be clamped in the AA_ALPHA && AA_VELOCITY_WEIGHTING code block that was removed recently.

Generated native code for AnimBPGC - some preliminary changes.
Refactor: UAnimBlueprintGeneratedClass is not accessed directly in runtime. It is accessed via UAnimClassInterface interface.
Properties USkeletalMeshComponent::AnimBlueprintGeneratedClass and UInterpTrackFloatAnimBPParam::AnimBlueprintClass were changed into "TSubclassOf<UAnimInstance> AnimClass"
The UDynamicClass also can deliver the IAnimClassInterface interface. See UAnimClassData, IAnimClassInterface::GetFromClass and UDynamicClass::AnimClassImplementation.

Change 2721727 on 2015/10/08 by Mike.Beach
(WIP) Setup the cook commandlet so it handles converted assets, replacing them with generated classes.
- Refactored the conversion manifest (using a map over an array)
- Centralized destination paths into a helper struct (for the manifest)
- Generating an Editor module that automatically hooks into the cook process when enabled
- Loading and applying native replacments for the cook
Change 2723276 on 2015/10/09 by Michael.Schoell
Blueprints duplicated for PIE will no longer register as dependencies to other Blueprint.

#UEBP-13 - Performance capture landing page
#Branch UE4
#Proj BlueprintProfiler, BlueprintGraph, EditorStyle, Kismet, UnrealEd, CoreUObject, Engine
Change 2724613 on 2015/10/12 by Ben.Cosh
Incremental update for blueprint profiler to fix the way some of the reported stats cascade through events and branches and additionally some missed bits of code are refactored/removed.
#Branch UE4
#Proj BlueprintProfiler
#info Whilst looking into this I spotted the reason why the stats seem so erratic, There appears to be an issue with FText's use of EXPERIMENTAL_TEXT_FAST_DECIMAL_FORMAT which I have reported, but ideally disable this locally until a fix is integrated.

Change 2727395 on 2015/10/13 by Mike.Beach
(WIP) Second pass on the Blueprint conversion pipeline; setting it up for more optimal (speedier) performance.
* Using stubs for replacements (rather than loading dynamic replacement).
* Giving the cook commandlet more control (so a conversion could be ran directly).
* Now logging replacements by old object path (to account for UPackage replacement queries).
* Fix for [UE-21947], unshelved from CL 2724944 (by Maciej.Mroz).

Fix for crash in UDelegateProperty::GetCPPType when called on a function with no OwnerClass (events)
Change 2727968 on 2015/10/14 by Maciej.Mroz
Since ConstructorHelpers::FClassFinder is usually static, the loaded class should be in root set, to prevent the pointer stored in ConstructorHelpers::FClassFinder from being obsolete.
FindOrLoadClass behaves now like FindOrLoadObject.

Change 2728139 on 2015/10/14 by Phillip.Kavan
we now use an enum similar to UE4 with Fatal, Error, Warning, Display, Log, Verbose, and VeryVerbose
Log will only go to the log file unless -verbose is passed on the command line
reduced some of the output from UAT to be Log only
