Change 3284872 on 2017/02/03 by Graeme.Thornton
Seperate pak cache granularity from pak signing chunk size
Change 3285765 on 2017/02/03 by Graeme.Thornton
Fix stats warnings because each slate new loading screen thread has the same stat name, but is assigned to a different thread
#jira UE-41478
Change 3286913 on 2017/02/04 by Ben.Marsh
IncludeTool: Merging fixes.
* Don't remove existing forward declarations unless explicitly instructed to do so. Files are optimized with these declarations in place, so removing them can cause output files to fail to build. It can be a useful separate step though, so expose it as a command-line option instead.
* Add a specific option for which files should be output by the tool. Any files which are excluded from this list are treated specially when generating output files, so as to prevent them from causing files to be omitted from other files that include them. Also add an option to force this mode for all headers, for use when testing formatting/include path generation.
Change 3287100 on 2017/02/05 by Ben.Marsh
UBT: Move platform settings into platform-specific TargetRules objects.
Change 3287106 on 2017/02/05 by Ben.Marsh
Merge UEBuildPlatformContext into UEBuildPlatform. Now that targets can have platform-specific settings, there is no need to separate a platform class which contains target-specific information.
Change 3287398 on 2017/02/06 by Steve.Robb
Fix for UHT failing when -WarningsAsErrors and -Verbose are specified together.
Change 3287399 on 2017/02/06 by Steve.Robb
Log verbosities made more readable in the debugger.
Change 3287410 on 2017/02/06 by Steve.Robb
Fix for TStructOpsTypeTraits where WithCopy gives a different result between specializing the traits and not providing WithCopy and not specializing the traits at all.
#fyi marc.audy
Change 3288020 on 2017/02/06 by Ben.Marsh
Prevent forward declaration of the ITextData class. We need to include the header for the debugger visualizers to work correctly.
Change 3291817 on 2017/02/08 by Steve.Robb
New EBlueprintCompileReinstancerFlags used to construct FBlueprintCompileReinstancer, instead of lots of bools.
Change 3292090 on 2017/02/08 by Graeme.Thornton
Crash fix - don't update font engine services if it was never created
#jira UE-33953
Change 3292993 on 2017/02/08 by Ben.Marsh
Add an option to disable force-including PCHs for files in the non-unity working set. (bAdaptiveUnityDisablesPCH)
Change 3293231 on 2017/02/08 by Ben.Marsh
BuildGraph: Allow overriding the changelist that a badge should be displayed for (with the Change="" attribute on the Badge declaration in XML), so the code changelist can be used if necessary. Also link to the failed step if only one has failed.
Change 3294213 on 2017/02/09 by Ben.Marsh
EC: Allow setting a property on frequent CI jobs that allows us to exclude it from job searches for generating the dashboard. Filtering on the client side is causing dashboard pages to be almost empty.
Change 3294753 on 2017/02/09 by Ben.Zeigler
#jira UE-41151 Fix UObjectLibrary::RemoveObject to remove from the correct array, and add comment mentioning that the dynamic use of Object Library is semi-deprecated
Change 3296070 on 2017/02/09 by Ben.Zeigler
Explicitly turn off Copy for a struct that has a linked list internally. I think turning Copy on by default for all non POD Types is pretty risky and is likely to crash for other games. In this case it was being copied for network replication, and it didn't have one defined so the default C++ one copied the linked list and crashed on destruction.
Change 3296420 on 2017/02/10 by Graeme.Thornton
Remove remaining references to AES_KEY, instead using the encryption key delegates to access the key where needed
Refactored encryption and signing key access in unrealpak to make it easier to use
Change 3296609 on 2017/02/10 by Ben.Marsh
BuildGraph: Fix error running the <Copy> task with an empty "From" argument.
* FileSystemReference.IsUnderDirectory() was not correctly handling cases where the directory was a root directory (and has to end in a path separator)
* FilePattern.AsDirectoryReference() with an empty token would append a path separator to an empty string, resulting in it referencing the root directory rather than the given base directory.
Change 3297440 on 2017/02/10 by Ben.Marsh
UBT: Move the FileFilter class into UnrealBuildTool.
Change 3297725 on 2017/02/10 by Ben.Zeigler
#jira UE-39199 Fix issue with enum value redirects using the wrong short or long name, it now fully supports both.
Clean up a lot of confusingly named and broken functions on UEnum:
#jira UE-41348 Deprecate FindEnumIndex, GetEnum, GetEnumName, replace with GetIndexByName, GetNameByIndex, and GetNameStringByIndex and clean up warnings
#jira UE-38187 Deprecate GetDisplayNameText and GetEnumText, replaced both with GetDisplayNameTextAtIndex which is now callable outside the editor and has a better comment
Deprecate FindEnumRedirects and replace with GetIndexByNameString. Fix code to not check the redirects array 5 times per enum lookup
Fix GetValueAsString to actually act on a value, not an index. This matches common usage and the function's name
While fixing deprecation warnings on internal games, fixed dozens of cases where it was using Index functions when it should have been using Value functions
Delete some now redundant enum editor code and pipe everything through UEnum
Change 3297979 on 2017/02/10 by Ben.Zeigler
Fix issues parsing Enums that are literally the string "None", which is allowed but leads to some odd behavior
Change 3298299 on 2017/02/10 by Steve.Robb
TTuple improvements:
- equality comparable
- serializable
- in the correct folder
2-tuples are specialized to be syntactically compatible with both TPair and TTuple.
TPair is now an alias for a 2-tuple and is no longer bound to TPairInitializer.

Change 3298460 on 2017/02/11 by Ben.Marsh
UGS: Set the correct result from running custom tasks.
Change 3298462 on 2017/02/11 by Ben.Marsh
UBT: Fix some deprecated messages that have the wrong release version, and add a better message for how ModuleRules constructors need to be updated.
Change 3299447 on 2017/02/13 by Graeme.Thornton
Fix AES and pak signing key embedding for content only projects
- Force temp target when any keys are specified by project config
Change 3299649 on 2017/02/13 by Steve.Robb
PLATFORM_HAS_DEFAULTED_OPERATORS fixed.
Other obsolete compiler switches removed.
Change 3299787 on 2017/02/13 by Steve.Robb
IsAbstract() for testing if a reflected native type contains pure virtual functions. Needed for BP nativization.
#fyi robert.manuszewski
Change 3300576 on 2017/02/13 by Ben.Marsh
EC: Add support for starting builds on any agent type. Mapping from agent types to resource pools is stored in an EC property sheet (/Generated/<Stream>/AgentTypes), allowing EC procedures to map it to a resource pool from a parameter.
Change 3300600 on 2017/02/13 by Ben.Marsh
EC: Add the -ClearHistory argument to UAT run to export BuildGraph settings, to allow running on incremental workspaces.
Change 3300624 on 2017/02/13 by Ben.Marsh
Switch incremental builds for all streams to start up on the incremental agent.
Change 3302134 on 2017/02/14 by Steve.Robb
UnrealCodeAnalyzer removed.

Fix crash cooking odin with default command line
#jira UE-41952 Delete StealthTeleport map that crashes on load, and update default cook list that gets used if nothing specified
Change 3303002 on 2017/02/14 by Ben.Zeigler
#jira UE-41061 Fix it so editor only filtering on savepackage is uniformly applied regardless of if it's at package or object level
#jira UE-41880 Rewrite editor/client/server only filtering logic in SavePackage to fix various bugs. It now does all of the filtering up front, and won't process any filtered objects for imports or exports
Rename NotForEditorGame to NotAlwaysLoadedForEditorGame and improve comments, this flag says that the asset should be loaded EVEN IF it is editor only, it does not affect loading for normal objects
Change the non-map cook flags to RF_Public instead of RF_Standalone. Blueprint classes aren't RF_Standalone so were only being cooked before due to an accident of the dependency checker
Change it so anything with a Transient outer is marked transient at save time. These objects would not save out properly anyway
Fix it so -cooksinglepackage works properly again and excludes localization and startup packages
Tested with Fortnite and Odin, Odin works but with lots of warnings with nativization on which I need to investigate
Change 3303084 on 2017/02/14 by Ben.Zeigler
Attempt to get Nativization and EDL working without warnings
Change 3305153 on 2017/02/15 by Ben.Zeigler
Fix Fortnite and Orion cook, I don't understand why this passed my local testing
Fix the CDO subobject finder to actually return things instead of doing nothing, and fix a shadow variable warning
Change 3305959 on 2017/02/16 by Gil.Gribb
UE4 - Tweaked out the EDL loader for the switch with benefits to all platforms.
Change 3306159 on 2017/02/16 by Ben.Marsh
Fix path to target binaries when building non-monolithic in a unique build environment.
Change 3306584 on 2017/02/16 by Steve.Robb
UEnum internal functions renamed from Index to Value.
GetValueAsString_Internal() parameter now takes an int64, as is expected for enum values.

#jira UE-42055 Second half of matinee redirector fix
Change 3308840 on 2017/02/17 by Matthew.Griffin
Reimplementing CL#3305808 from 4.15
Changed QA label build process so that it only allows version with 3 components (we always add the .0 for initial releases)
Change 3309115 on 2017/02/17 by Ben.Marsh
Windows: Fix the GetModulesDirectory() function always returning the engine binaries directory. It's possible to build non-monolithic targets which output all engine binaries to the game binaries directory - a requirement to being able to set game-specific defines or build settings, because we don't want shared engine binaries to be tainted with them. The module manager needs to be able to operate early on, before many of the game settings have been initialized, so just return the directory containing the Core module instead.
Change 3309120 on 2017/02/17 by Ben.Marsh
Fix support for creating modular builds which don't use the shared build environment.
Change 3309125 on 2017/02/17 by Ben.Marsh
Require that -CookDir arguments are specified separately on the command line. '+' is a valid path character (and common in build versions), so we shouldn't treat it as an argument separator.
Change 3309128 on 2017/02/17 by Ben.Marsh
Fix UnrealPak failures when enumerating all files from a source directory, if that directory happens to contain spaces.
Change 3309131 on 2017/02/17 by Ben.Marsh
Fix list of discovered assets being cleared by second call to FindFilesRecursive() when building DDC. Disable the -cookdir parameter again.
Change 3309140 on 2017/02/17 by Ben.Marsh
UAT: Fix exception moving a file from one location to another if the target directory does not exist.
Change 3309212 on 2017/02/17 by Ben.Marsh
Fixes/improvements for mod editor and code mods:
* A separate top-level project is generated for each code mod in the Visual Studio solution.
* Plugin descriptors now have a flag to identify themselves as mod as opposed to a regular game plugin, which prevents project plugins from getting their own VS project. New mods created with the mod editor will have this set by default, as do the three existing sample mods.
* Cleaning and building code mods will never modify engine binaries. Presence of the Engine/Build/InstalledProjectBuild.txt file is used to indicate running in this environment. This flag also disables options to edit metadata for non-mod plugins in installed builds.
* Plugin browser now includes a separate category for mods.
* Mod editor now behaves as an "installed" program by default, and will use the user's home folder for storing settings.
Change 3309231 on 2017/02/17 by Steve.Robb
Fix for Ar << bSomeBool where Ar is a derived class which overrides an operator<<.
#jira UE-42052
Change 3309248 on 2017/02/17 by Ben.Marsh
Add support for hot-reloading game plugin modules from Visual Studio, as long as their module returns IsGameModule() = true.
Change 3309257 on 2017/02/17 by Ben.Marsh
Prevent game binaries from being renamed for hot reload when working with installed projects.

FNativeClassHeaderGenerator::CurrentSourceFile stack replaced with C++ stack.
Change 3311893 on 2017/02/20 by Ben.Marsh
UGS: Add support for notifying users if CIS steps fail for content changes. Badges which test content should be listed in the [Notifications] section of the project-specific INI file, through +ContentBadges= lines.
Change 3313966 on 2017/02/21 by Ben.Marsh
Fix EC parsing of error messages output by the editor in the form "LogXYZ:Error:". Greedy optional subexpression in regex was matching everything until a space, so terminate a colon too.

MAJOR FEATURES + CHANGES
==========================
Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.
[CL 3209342 by Ben Marsh in Main branch]
UE-18771 - Collections log spam when building engine dlls that live in the same directory as a running instance of the editor
The collection manager now ensures that the collection directories exist on disk before it starts watching them, and will also ignore the "system" collection directory (as that is blank and was causing it to watch for changes in the Binaries folder).
As a belt-and-braces measure, FCollectionManager::TickFileCache will also now ensure that a file ends with the ".collection" extension before attempting to process the file as a collection.
[CL 2627607 by Jamie Dale in Main branch]
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 used to maintain an up-to-date cache as soon as a change happened. This lead to extra complexity in some cases, and often would keep caches up-to-date that weren't currently even being used.
Adding, removing, or updating a collection will now just mark the relevant parts of the cache as dirty so that they can be updated (using a well defined, safe, full update) the next time something requests them.
[CL 2610959 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]
UE-17561 - Collections allow for several special characters that are not normally allowed
UE-17549 - User gets no warning for invalid Characters when naming a Collection
UE-17538 - Add a Character limit for naming a collection
The list of valid characters now matches that of assets and folders in the Content Browser, and the user is informed when they try and use an invalid character.
The collection name is also now restricted to NAME_SIZE to avoid a crash if a user entered a name that was too long.
[CL 2609261 by Jamie Dale in Main branch]
UE-17678 - Limit what type of collections can be nested
Local collections can now only contain other local collections.
Private collections can now only contain local or private collections.
Shared collections can still contain any other kind of collection.
[CL 2607624 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]
The collections manager now stores a reverse look-up from the objects within its collections, to the collections that contain that object. This avoids the GetCollectionsContainingObject and GetCollectionsContainingObjects functions having to iterate the collections for each object queried, which can be a large win for large sets of objects.
This also adds some functions needed for the quick asset management feature.
[CL 2570748 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.
[CL 2560621 by Jamie Dale in Main branch]
