Change 2949393 on 2016/04/20 by Graeme.Thornton
Orion non-pak file security.
- Removed security bypass code from platform pak file
- Added a delegate to pak file code which allows the game to decide whether a file should be allowed or not
- Added an orion delegate which whitelists appropriate files

Change 2949032 on 2016/04/19 by Zak.Middleton
#orion - Lower default NetUpdateFrequency for minions (10->6). Avoid excessive latency for some knockback/knockup abilities that would have noticeable lag by forcing an update sooner when they are triggered.
This should have the following effects:
1. Reduce server CPU cost (we tick minions at the net frequency).
2. Reduce server bandwidth
3. Reduce client CPU cost (we move character capsules and perform overlaps when new positions are received).

Change 2946645 on 2016/04/18 by Richard.Fawcett
When promoting a buidl to staged, prevent enumeration of files already in S3
Enumerating files in S3 is a slow process, and it turns out that simply uploading all chunks blindly is more efficient than enumerating existing chunks and selectively uploading only the new ones.
#rb Leigh.Swift
#tests This technique has already been used in launcher promotions for several months
Change 2946622 on 2016/04/18 by Richard.Fawcett
By default, when enumerating chunks from a manifest file, skip checking they exist on disk at enumeration time.
This will fail anyway further down the line if the files don't exist, but will improve speed of stage promotions by around five minutes. In practice, we have NEVER seen a job fail at this point because of the existence check.
#rb Leigh.Swift
#tests Ensure that output of ExtractDataFilenamesFromManifest method is identical both with and without bSkipExistsCheck specified.

Fix for OR-19778
When some pooled systems are reused, on init they have a non zero lod level but the emitter instances are created at LOD 0 initially.
So the component did not think it had to update it's LOD but the emitters were not at the correct LOD.
Have forced a LOD set on init when the component LOD is non-zero.

OR-19392 Ensure condition failed: (*RequiresInitialization == 0) on loading into PVP match
- Removing ensure since there is a rare edge case where it's possible for a sound looping node may get ResetChildren called twice.
- Condition is when a child random node o fa looping node has a blank entry and results in no sound chosen in a given frame (which results in ResetChildren getting called). Later in the frame, if a sound had previously been playing with an active sound, it will have stop called on it, which will call NotifyWaveInstanceFinished and hit the ensure. Simply using the branch to check if the looping node has been initialized will work fine in this and other cases.

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 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.

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.

MAJOR FEATURES + CHANGES
==========================
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.

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.

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.

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.

- Append the source shader name to the GLSL when debug info is enabled to make it easier to debug.
- Always preserves GLSL flow control for Mac GLSL to improve performance on 2 of 3 vendors.
- Exposes a CVar to control whether to preserve or avoid GLSL flow-control for other shader platforms. The default remains to avoid flow control in GLSL.

[CL 2460254 by Allan Bentham in Main branch]
- This is especially important on OS X OpenGL where these hitches can be equivalent to several frames, so it is enabled by default for this platform.
- The logging of draw calls is turned on/off with r.UseShaderDrawLog and incurs a fixed overhead as all RHI state is tracked & recorded into the shader cache.
- The actual predrawing is turned on/off with r.UseShaderPredraw and requires an existing cache to be useful, the predrawing takes place at frame-end and can be controlled with r.PredrawBatchTime which the time in ms to spend predrawing each frame until complete, or -1 to do it in one go (currently the default).
- The shader cache is now also versioned with the game able to supply a version distinct from the engine, so that old caches may be invalidated if/when required.
- The shader cache is now compatible with OpenGL SM4 & SM5 on Windows & probably Linux too.
- It may not work correctly with desktop ES2 emulation as that is still untested.
- To make it easier to add to other RHIs the API has been made simper to avoid lots of exposed branches.
#codereview michael.trepka, dmitry.rekman
[CL 2460109 by Mark Satterthwaite in Main branch]
- Shaders which emit layout location data use INTERFACE_LOCATION & INTERFACE_BLOCK macros to defer to the runtime whether they can be used as separable or non-separable shaders.
- The runtime supplies the correct #define for each so that the shaders still work on platforms where the glLinkProgram implementation fails with separable shader code.
- Shader model 5 platforms (GLSL 430 or ES 3.10) which were already specifying & using layout location data continue to do so, even when using glLinkProgram.
- The 'OpenGL.UseSeparateShaderObjects' console variable allows switching between SSO/Link modes between executions, but not dynamically at runtime.
- Only defaults to on for Mac as that is the only platform which can guarantee that the extension is always available & so far the most tested platform.
- Updated hlslcc binaries are supplied for Mac, Linux & Windows.
- Added an OpenGL RHI stat for shader first draw time so that it is easy to see why hitches occur during runtime due to in-driver shader compilation.
