Change 2828332 on 2016/01/14 by Matthew.Griffin
Ensure that warnings from Dynamic Compilation of build.cs files are propagated up to user when compiling in Visual Studio etc.
Change 2828335 on 2016/01/14 by Matthew.Griffin
Renaming AddThirdParty... functions to AddEngineThirdParty... so it's clear we're talking about third party libraries within the engine directory. This removes another couple of RunningRocket checks and uses the IsMonolithic property now.
Change 2831365 on 2016/01/16 by Ben.Marsh
Add a UAT command to remove any temp storage directories older than a specified length of time, and disable the GUBP node to do so when running with -NewEC. Better to set this up as a separate scheduled task for each temp storage folder we have, rather than run it as part of GUBP builds above a certain size.
Change 2832166 on 2016/01/18 by Ben.Marsh
Make INI file parsing much more tolerant to errors, because it prevents the build system from starting up. Now outputs warnings rather than throwing exceptions.
Change 2835725 on 2016/01/20 by Matthew.Griffin
Removed more uses of RunningRocket functions
Switch Linux staging check to see if required files exist until switched to using receipts
Always stage CrashReporter for Linux
Mac and Linux will not use Compile Lean And Mean when generating project files
Allow normal DynamicCompilation check to occur in binary builds
Allow XMPP dependency on WebRTC now that it's publically distributed
Change 2835864 on 2016/01/20 by Matthew.Griffin
Made sure -rocket is passed when generating project files as this has to work from UnrealVersionSelector with every version of the Engine we've released.
Also tidied up some arguments that are set in UVS and never used.
Change 2839932 on 2016/01/22 by Matthew.Griffin
Removed last uses of RunningRocket from UnrealBuildTool
Changed Mac Build.sh so that it doesn't try to build UBT so that it can be used in installed builds the same way as windows.
Combined code doing very similar things for single games and rocket projects.
Removed check on whether to add client and server targets in Rocket as we don't distribute the .target.cs files.
Removed RunningRocket function and the code checking for -rocket on the command line
Change 2846971 on 2016/01/28 by Matthew.Griffin
Replaced RunningRocket with IsEngineInstalled for all Engine programs that won't need to be built.
Change 2853879 on 2016/02/03 by Matthew.Griffin
Added UnrealLightmass to list of programs to build when Build Solution is used and Editor configuration is selected

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.
Change 2731928 on 2015/10/16 by Michael.Trepka
PR #1659: Mac/Build.sh handles additional arguments (Contributed by judgeaxl)
Change 2731934 on 2015/10/16 by Michael.Trepka
PR #1618: added clang 3.7.0 -Wshift-negative-value ignore in JpegImageWrapper.cpp (Contributed by bsekura)
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.

Change 2736722 on 2015/10/21 by Daniel.Lamb
Improved performance of cooking stats system.
Change 2737172 on 2015/10/21 by Daniel.Lamb
Improved cooking stats performance for ddc stats.
- The code that handles initial setup (command line processing, rlimits and debugger) is now shared between engine, UFE and SlateViewer.
[CL 2679796 by Dmitry Rekman in Main branch]
Ensures that CEF is uninitialized and has no threads hanging around, so the process will exit.

[CL 2664648 by Keli Hlodversson in Main branch]
Changed everything using SlateReflector to list it as a dynamic dependency. Nothing should ever need to link directly to SlateReflector as it just provides an interface for spawning the various debug UIs, such as the WidgetReflector.
Went through and made sure that the Engine/Runtime modules that use SlateReflector aren't using it in a shipping build. Also removed the testing code from AppFramework, and made sure that you can't try and spawn the test suite in a shipping build.
[CL 2660803 by Jamie Dale in Main branch]
* See SlateStats.h for details on the new system, which allows for full hierarchical profiling with limited overhead.
* Moved SWidget::GetVisibility() out of line so we can instrument it without a full recompile.
* Widget debug info now uses FName to store the line number of the file. Keeps it in one place and the new stats system can utilize it as an FName.
* Exposed SWidget CreatedInFile debug info as an FName so new stats system can use it.
* FSlateVertex no longer uses FVector4, which is an aligned struct. Switched to float[4] instead. Goes from 48 to 36 bytes.

[CL 2417281 by Wes Hunt in Main branch]
To remove its use in AppFramework and keep using it in the SlateViewer app, I needed to define its tab in AppFramework and spawn it as a nomad tab in SlateViewer.
[CL 2358266 by Matthew Griffin in Main branch]
Removes depency on WebBrowser project from Slate, it now depends on Slate instead.
Removed functions from Singleton interface that are no longer needed.
Get the Slate renderer when needed instead of keeping reference.
Added call to FTicker::Tick function in Slate viewer app so that Web Browser will continue to work.
[CL 2330030 by Matthew Griffin in Main branch]
* Moved Slate.h into SlateBasics.h and began shifting less commonly used headers into SlateExtras.h.
* Slate.h now simply includes SlateBasics.h and SlateExtras.h.
* Slate.h includes a deprecated warning now to indicate that SlateBasics.h + specific includes should be used instead.
* Moved dozens of inlined functions using Slate widgets into .cpp files to avoid header dependencies.
* All code samples now include SlateBasics.h and SlateExtras.h so future shifts will not break most those projects, but not trigger the deprecation warning of including Slate.h.
