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/...
Change 2726266 on 2015/10/13 by Lee.Clark
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.

PR #1659: Mac/Build.sh handles additional arguments (Contributed by judgeaxl)
Change 2731934 on 2015/10/16 by Michael.Trepka

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.

MAJOR FEATURES + CHANGES
==========================
Change 2718441 on 2015/10/06 by Ben.Marsh@Ben.Marsh_T3245_Stream
Allow nodes to be added with an "explicit" frequency, meaning that they'll only be part of manually triggered builds (not CIS).
Change 2718698 on 2015/10/06 by Ben.Marsh@Ben.Marsh_T3245_Stream
Add a type of node that can execute an arbitrary sequence of tasks, and allow constructing graphs of such nodes from an XML file.
Change 2723013 on 2015/10/09 by Ben.Marsh@Ben.Marsh_T3245_Stream
Small utility to quickly capture a workspace, or delete files to restore the workspace to a previously captured state (and output a p4 sync list to restore it)
Change 2744521 on 2015/10/28 by Matthew.Griffin@Matthew.Griffin_G5772_BuildStream
Adding config entries to determine which platforms/configurations are available
Currently only written out as part of the Rocket Build process but could be done elsewhere for other types of installed build.
A near identical singleton class is used in both C++ and C# to load the config section and check whether configuration/platform combinations are valid.
Change 2773723 on 2015/11/19 by Ben.Marsh@Ben.Marsh_T3245_Stream
Copying UnrealGameSync into Engine/Source/Programs.
Change 2773914 on 2015/11/19 by Ben.Marsh@Ben.Marsh_T3245_Stream
PR #1687: [GitDependencies] New feature: ignore file support (.gitdepsignore) (Contributed by nbjk667)
Change 2775317 on 2015/11/20 by Ben.Marsh@Ben.Marsh_T3245_Stream
Add a -listtps option to UBT, which will find all the TPS files in any directory that's compiled into a target.
Change 2780832 on 2015/11/25 by Ben.Marsh@Ben.Marsh_T3245_Stream
Allow compiling a single file in UBT. Pass -singlefile=<Path> on command line to UBT to use.
Change 2781071 on 2015/11/25 by Ben.Marsh@Ben.Marsh_T3245_Stream
Precompile all valid engine modules for Rocket by default. Modules may set the PrecompileForTargets field to control which configurations they should be compiled for. Modules which currently fail to compile have this set to
PrecompileTargetsType.None.
#codereview Matthew.Griffin
Change 2784469 on 2015/12/01 by Matthew.Griffin@Matthew.Griffin_G5772_BuildStream
Added -FastPDB commandline parameter for UBT, so that we can make use of the /DEBUG:FASTLINK option in VS2015
Change 2784722 on 2015/12/01 by Matthew.Griffin@Matthew.Griffin_G5772_BuildStream
Made -FastPDB option part of BuildConfiguration instead of checking commandline at each place it's used. Also added option to override if someone doesn't want it automatically added to their project files.
Change 2787501 on 2015/12/02 by Ben.Marsh@Ben.Marsh_T3245_Stream
Restore change to gather VC environment directly from registry.
#lockdown Nick.Penwarden
[CL 2790002 by Ben Marsh in Main branch]
- Rocket doesn't bundle Linux libs, making code-based projects (and projects with third-party plugins) fail during compilation.
- Updated messaging to reflect this.
- Also added a SDK check for Linux and a 'getting' started UDN page.
- Updated Linux README for 4.8.
#codereview Peter.Sauerbrei, Ben.Marsh, Jeff.Wilson
[CL 2543338 by Dmitry Rekman in Main branch]
- Moved HighQualityLightmap support check to IOSTargetPlatform so it can check project settings for Metal support
- Fixed some issues running on an x86_64 device
- Cleaned up some unused functions in TargetPlatform
#codereview niklas.smedberg
[CL 2478853 by Josh Adams in Main branch]
- Fixes to the Mac HTML5 Device selection. .app files now work correctly.
- Re-enabled HTML5 in Mac Editor.
- Added HTML5LaunchHelper executable to clean up the process of LaunchOn for HTML5.
- Improve HTML5 SDK Settings Editor interface. Only the emscripten install directory is needed now, SDK version are automatically picked up and selected for use.
- Change UnrealPak to also account for bytes saved (>64KB) and percentage size of original file (<90%) when choosing to automatically turn off compression.
- Added Server Port option for HTML5 deploy to stop clashes on port 8000
- Adding more logging for use during debugging & tracing.
- Added an option to turn on HTML5 tracing api and added calls to the api.
- Fix up check() macros to throw alert messages and be more clear that something has gone wrong on HTML5.
#codereview Ankit.Khare
[CL 2452979 by James Moran in Main branch]
- Enabled ES31 for GitHub/P4 users (currently only works on a Tegra K1 with recent system software)
- Always use separate APKs - this means that all APKs will have -armv7-es2 (or whatever) in their name. This may affect scripts, etc people have written
- Fixed a bug when using multiple java libraries (for users who add their own libs)
- Properly collapse Android devices into a single device with multiple variants. LaunchOn will now choose the best format based on the connected device. If you want to override the format, you will need to use the ProjectLauncher
- Added Android serial number to the device type, in case you have multiple devices of the same type (also fixes [UE-3770])
#codereview niklas.smedberg,chris.babcock
[CL 2385821 by Josh Adams in Main branch]
Added a fallback to treat the path passed-in as a documentation path if the asset path doesnt correspond to a BP.
