Change 3048267 on 2016/07/13 by Ben.Marsh
BuildGraph: Allow more permissive list of characters for node names; just restrict against characters which are illegal in filenames. Allows creating aggregate names which match job names (eg. "Editor, Tools & Monolithics").
Change 3048293 on 2016/07/13 by Ben.Marsh
BuildGraph: Allow passing -listonly without a specific -target=... parameter in BuildGraph, to see the contents of the entire script.

Change 3051522 on 2016/07/15 by Ben.Marsh
BuildGraph: Change spawn task to fail if a non-zero exit code is returned by an external program. The minimum exit code to be treated as an error can be set using the "ErrorLevel" attribute, similar to ERRORLEVEL in DOS.
Change 3051770 on 2016/07/15 by Ben.Marsh
UGS: Add support for narrowing virtual streams; fetch event and precompiled binaries for parent stream instead.
Change 3052990 on 2016/07/17 by Ben.Marsh
Show the names of people with notifications disabled in the heading of failure emails, so it's clear that they're not on CC.
Change 3053556 on 2016/07/18 by Ben.Marsh
BuildGraph: Add a explicit <Option> tag instead of the <Property Default=""/> shenanigans, so that properties that are meant to be modified by the user are listed explicitly. Supported attributes are "DefaultValue" (which specifies a default if the user does not set it on the command line), "Description" (which explains the purpose of the option to users, which is displayed in a table when BuildGraph is invoked with the -listonly argument), and "Restrict" (which specifies a regex to validate an argument supplied by the user).
Also add an <EnvVar Name="Blah"/> tag which imports the given environment variable as a property (or sets it to "" if it doesn't exist), and rename the <Choose>/<Option>/<Otherwise> triple to <Switch>/<Case>/<Default> to avoid confusion with the new <Option> tag.
Change 3053688 on 2016/07/18 by Ben.Marsh
Update build scripts to link to p4-swarm rather than p4-web in dashboard pages and notification emails.
Change 3054039 on 2016/07/18 by Ben.Marsh
Fix confusing message when compiler isn't installed if the target forces VS2013

Change 3055671 on 2016/07/19 by Ben.Marsh
Remove incomplete UWP integration from UE4.
Change 3055943 on 2016/07/19 by Ben.Marsh
Remove the WinRT target platform.
Change 3056270 on 2016/07/19 by Ben.Marsh
Core: Move VectorRegister.h include to eliminate include dependency on UnrealMathUtility.h
Change 3056390 on 2016/07/19 by Ben.Marsh
Core: Directly include headers required by default JsonWriter template instantiation.
Change 3057444 on 2016/07/20 by Ben.Marsh
UBT: Fall back to checking for the VS140COMNTOOLS environment variable if we couldn't determine the Visual Studio installation directory from the registry. Allows using the standalone Visual Studio build tools to compile UE4.
Change 3058337 on 2016/07/20 by Ben.Marsh
Remove EnvVarsToXML. All target platforms now determine their compile environment directly from the registry.
Change 3058348 on 2016/07/20 by Ben.Marsh
Disable optimization for all automation projects. They don't generally do anything particularly CPU intensive, and VS2015 optimizations are inhibitive to debugging.
[CL 3058822 by Ben Marsh in Main branch]
Individual projects select 2013 support through their target.cs files. This is already setup for the correct projects and no other projects should use 2013.

Fix some memory leaks.
Change 2842831 on 2016/01/25 by Mark.Satterthwaite
Metal implementation for RHIBlockUntilGPUIdle.
Change 2842838 on 2016/01/25 by Mark.Satterthwaite
When using parallel command contexts in Metal we must ensure that the FRingBuffer is still valid, which means some smart/weak pointers are in order. We should also ensure that functions that may return auto-released objects are appropriately wrapped with scoped autorelease pools. Texture creation failures should also be fatal as we never expect that to occur.
Change 2842914 on 2016/01/25 by Mark.Satterthwaite
Change assert in MetalTexture's format-shifting SRV constructor to enforce the Metal textureView limits:
1. No format shifting for MSAA color buffers.
2. No access to stencil in MSAA packed depth/stencil surface.
This will allow Metal MSAA support to work on iOS when using separate depth & stencil textures since there's no format shifting involved there.

Change 2843028 on 2016/01/25 by Mark.Satterthwaite
In Metal wwitch to blit on the correct context when copying out the stencil data into the stencil SRV copy.
Change 2845531 on 2016/01/27 by Lee.Clark
PS4 - Fix memory alignment for back buffers
* Fix memory alignment for MapLargeBlock
* Fix available direct memory tracking
Change 2846491 on 2016/01/27 by Jeff.Campeau
2015 compile fixes for Orion
Change 2847395 on 2016/01/28 by Mark.Satterthwaite
Clear the stencil-SRV copy to 0 in Metal using a blit when created to avoid artefacts if used prior to the parent texture being rendered.
#jira UE-25834
Change 2847419 on 2016/01/28 by Mark.Satterthwaite
Apply the same fix to OpenGL's Stencil SRV logic as CL #2847395 applies to Metal.
Change 2848093 on 2016/01/28 by Mark.Satterthwaite
Cache parallel encoding Metal contexts & reuse them rather than creating a new one each time in order to massively improve parallel encoding performance. This required adding a reset function to Metal's internal state-cache which calls the CommandEncoder wrapper's reset so we don't accidently retain previous state.
Change 2849469 on 2016/01/29 by Mark.Satterthwaite
Defer render & compute command encoder construction to draw/dispatch etc to eliminate redundant encoders that then perform unnecessary driver & GPU synchronisation work. Currently Clear loadActions force an encoder even if it would then be empty as otherwise we see incorrect rendering. This needs to be tracked and optimised away too in order to achieve the same performance as D3D11.
Change 2849820 on 2016/01/29 by Daniel.Lamb
Fixed issue where a single DDC back end would not create a hierarchy.

Change 2850762 on 2016/02/01 by Jeff.Campeau
System-wide critical section support for Xbox One
Change 2850763 on 2016/02/01 by Jeff.Campeau
Network and product config for Orion
Change 2852459 on 2016/02/02 by Mark.Satterthwaite
Temporarily disable the lazy render command-encoder construction while investigating why it turns some samples black in Metal SM5 mode.
Change 2853947 on 2016/02/03 by Mark.Satterthwaite
Fix some lazy encoder construction fallout which also means we don't need to recreate render encoder state when performing profiling - the next draw/clear will do that as required.
Change 2854015 on 2016/02/03 by Mark.Satterthwaite
Move Stencil SRV blitting into FMetalSurface::UpdateSRV called when binding the texture SRV instead of having it done immediately post-rendering. This should avoid paying for the blit when stencil SRV sampling is never used or multiple blits when render-encoders that write stencil are split up due to query buffer overflow or similar. The cost will be a blit per-bind instead which should be more predictable.
Change 2854142 on 2016/02/03 by Mark.Satterthwaite
Implemented GetTextureBaseRHI (brought over from Dev-Rendering CL #2853948) for Metal to avoid unnecessary virtual function call chain to resolve the FMetalSurface* from an RHI texture.
Change 2854222 on 2016/02/03 by Mark.Satterthwaite
Remove the uniform buffer resource caching from Metal to match Dev-Rendering CL #2853948.
Change 2854246 on 2016/02/03 by Mark.Satterthwaite
Removed the uniform buffer resource caching from OpenGLDrv & implemented GetTextureBaseRHI to avoid unnecessary virtual function calls to match Dev-Rendering CL #2853948.
Change 2854279 on 2016/02/03 by Mark.Satterthwaite
Remove direct access to the MTLCommandQueue, for parallel rendering to work we're going to need to do a bit of management that means its more sensible to keep it private.
Change 2855524 on 2016/02/04 by Lee.Clark
PS4 - Fix Grayscale SRGB support
[CL 2898161 by Josh Adams in Main branch]
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
[CL 2631062 by Peter Sauerbrei in Main branch]
#change UBT will check for API version of all UnrealHeaderTool binaries to detect partial syncs
#change Added BuildHostPlatform class for runtime platform abstraction
[CL 2245408 by Robert Manuszewski in Main branch]
