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.

Improved cooking stats performance for ddc stats.
UETOOL-332 - Collections 2.0
UETOOL-401 - Add support for dynamic collections
You can now reference both static and dynamic collections in the Content Browser text filter, including recursive references (the evaluator guards against cyclic collection references).
The text filter now recursively gathers up any dynamic collection references when the filter text is changed. These are then tested depth first as sub-expressions against each object, to see whether the object is "contained" within the given dynamic collection.
[CL 2615416 by Jamie Dale in Main branch]
UETOOL-332 - Collections 2.0
UETOOL-401 - Add support for dynamic collections
These collections can be created from a text search in the Content Browser, and allow you to store a search query so it can be reused or shared.
They have some limitations compared to static collections:
- As they never know what objects they actually contain, they can't be displayed in the "Collections" list in asset tooltips.
- They cannot contain child collections.
[CL 2615029 by Jamie Dale in Main branch]
UE-17782 - Editor must be restarted for New Collections to appear after syncing
These use FFileCache to avoid detecting changes that are made by the collection manager itself.
This also fixes some issues when merging collection sets together, and fixes some places where UI wouldn't update when a collection was changed due to an update or merge.
[CL 2612319 by Jamie Dale in Main branch]
This shows a little colored pip to the right of the collection items, where each color means:
Grey - Up-to-date and empty
Green - Up-to-date and not empty
Blue - Has local changes
Orange - Not at the latest revision
Red - Checked out by another user, in a conflicted state, or missing its source control provider
This also adds an "Update" and "Save" option to the collections context menu. Typically these won't be needed as collections mostly manage themselves, but since we now show when a collection is out-of-date or dirty, it makes sense to allow the user to take action to correct these states without having to leave the editor.
[CL 2610477 by Jamie Dale in Main branch]
UETOOL-332 - Collections 2.0
UETOOL-373 - Check robustness of Collections 2.0
The collection manager will now fix-up any references to redirectors within its collections once the asset registry has finished discovering all the available assets. It also adds a watcher so it can pick up any moves or deletes as they happen.
All of this fix-up is applied to the in-memory copy of the collection, and doesn't get persisted to disk until it needs to be (because referenced redirectors are being deleted). This helps to minimize issues with source control availability and shared/private collections.
This change also makes sure that objects that are being referenced by a collection will leave a redirector behind, and also adds some extra context (such as the collection name) to some of the source control errors that may be reported when saving a collection.
[CL 2602519 by Jamie Dale in Main branch]
UETOOL-332 - Collections 2.0
UETOOL-369 - Want nested collections with collapsing
We now have version 2 collections which maintain a persistent GUID for each collection. Existing collections will be lazily updated to this version when they need to be re-saved.
This GUID is used by child collections to keep track their parents, and the collections view (as well as the quick asset management) now show a tree of collections. Collections in the main collection view tree can be re-parented via drag and drop.
Performing Content Browser searches against a given collection will also test to see if an object exists in child collections, and the asset view will now show you folder entries for child collections when viewing a parent (if folders are enabled in your Content Browser view settings).
[CL 2593321 by Jamie Dale in Main branch]
UE-17109 - Collections cannot be created when using SVN as your SCC provider
The collection was trying to add itself to source control before the file had been created. Perforce allows this, but SVN and Git do not.
Additionally, SVN was trying to recursively commit any added parent folders when committing a file within those folders (required to avoid the commit operation failing), however that was failing to get the current SVN status of anything but the most immediate parent folder, causing the recusive check to fail.
[CL 2588523 by Jamie Dale in Main branch]
UETOOL-332 - Collections 2.0
Removed some duplicated data from FCollection (AssetList and AssetSet) as they had to be manually kept in sync. Only AssetSet exists now, and is converted into an array and sorted before being written to disk (to keep the order consistent for diffing). DiskAssetList has also been converted into a set (now DiskAssetSet) as this is only ever used for lookup queries.
All manually memory management has been removed from FCollectionManager, and the array of maps to collections has been converted into a single map using FCollectionNameType as its key. This simplifies collection lookup code in most cases, and removes the need to manually track the total number of collections outside of the map (NumCollections has now been removed).
Renamed ICollectionManager::GetCollectionsContainingAsset to ICollectionManager::GetCollectionsContainingObject as the function checks for any objects, not just assets.
Renamed FCollection::IsAssetInCollection to FCollection::IsObjectInCollection as the function checks for any objects, not just assets.
Made ICollectionManager::IsCollectionEmpty const.
Replaced all appropriate loop usage with range-based-for, and replaced any NULL with nullptr.
