MAJOR FEATURES + CHANGES
==========================
Change 3233612 on 2016/12/13 by Ben.Marsh
UGS: Fix cases where precompiled binaries are submitted for a content change.
Change 3235584 on 2016/12/14 by Ben.Marsh
UBT: Deprecate the overridable TargetRules.ShouldUseSharedBuildEnvironment() function; targets should specify which build environment to use by setting the BuildEnvironment field in their constructor instead.
Change 3235741 on 2016/12/14 by Ben.Marsh
UBT: Deprecate the SetupBinaries() callback on the TargetRules class. Instead of overriding this, targets may override their launch module through the "LaunchModuleName" property in their constructor, and add extra modules to the "ExtraModuleNames" field on the TargetRules object itself.
Change 3238176 on 2016/12/16 by Ben.Marsh
UBT: New XML config file parser. Now reads once at startup and can be applied to instanced objects rather than global fields, and caches parsed output in a binary form for quicker initialization on subsequent runs.
Change 3238249 on 2016/12/16 by Ben.Marsh
UBT: Add attribute-driven command line parser.
Change 3238462 on 2016/12/16 by Ben.Marsh
UBT: Include the Platform, Configuration and Architecture on the TargetRules. Add a constructor which takes the TargetInfo object and deprecate the parameterless one; these fields are currently initialized before invoking the constructor in RulesAssembly.
Change 3238564 on 2016/12/16 by Ben.Marsh
UBT: Deprecate the ModuleRules constructor which takes a TargetInfo argument. Replace it with a read-only wrapper around the target rules instead, so target-specific configuration options can be read without needing to access global static variables. Also require that it's passed to the base class constructor.
Change 3239919 on 2016/12/19 by Ben.Marsh
UBT: Remove the "PreferredSubPlatform" property. This is only used for Windows XP support, which is being retired anyway. Having the target define its own architecture is an awkward contractiction to maintain support for, since the target rules are constructed after the architecture already has been determined.
Change 3240061 on 2016/12/19 by Ben.Marsh
UBT: Remove ThirdPartyHeaderFinder. I don't think anything is using this any more.
Change 3240175 on 2016/12/19 by Ben.Marsh
UBT: Add the target name and project file location to the target rules.
Change 3240490 on 2016/12/19 by Ben.Marsh
UAT: Remove Mac staging code that requires UAT to compile and construct .target.cs files when packaging, to check bUseSteam and bUseCEF3 flags. libsteam_api.dylib is now staged at build time by adding it as a bundle resource, CEF3 is already marked as a runtime dependency by CEF3.build.cs, and UnrealCEFSubProcess.app is already marked as a runtime dependency from WebBrowser.build.cs.
Change 3240717 on 2016/12/20 by Ben.Marsh
UAT: Allow configuring UAT to run as if on a build machine by passing the -buildmachine argument on the command line.
Change 3240718 on 2016/12/20 by Ben.Marsh
UAT: Remove target-specific properties that are no longer used by staging (bUsesSlate, bUsesCEF3, etc...). This stuff should all be handled inside UBT.
Change 3241002 on 2016/12/20 by Ben.Marsh
UBT: Move most target configuration settings from UEBuildConfiguration to TargetRules. This encapsulates target specific settings that will allow instancing multiple targets in the future. To facilitate migration of settings to their new location, "UEBuildConfiguration" is now a property that returns the current target rules instance.
Change 3241027 on 2016/12/20 by Ben.Marsh
Only copy the Steamworks dylib into the app bundle for monolithic builds. For all other times, just add it as a runtime dependency.
Change 3241055 on 2016/12/20 by Ben.Marsh
UBT: Only store a ReadOnlyTargetRules object on the instanced build target; finalize the configuration before it's instantiated.
Change 3241156 on 2016/12/20 by Ben.Marsh
Update SwarmInterface.csproj to .NET framework 4.5, to match what all other C# tools are using.
Change 3241205 on 2016/12/20 by Ben.Marsh
Replace all uses of TargetRules.TargetType with TargetType.
Change 3241881 on 2016/12/21 by Ben.Marsh
UBT: Remove project file information from UEBuildContext base class. As configurable properties are moved on to the TargetRules object, it will no longer be a dependency to instantiate the platform with this path.
Change 3241895 on 2016/12/21 by Ben.Marsh
UBT: Remove toolchain support for Windows XP.
Change 3241908 on 2016/12/21 by Ben.Marsh
UBT: Move settings for windows targets into a WindowsTargetRules class, which is exposed for targets to modify via the TargetRules.WindowsPlatform field.
Change 3242835 on 2016/12/22 by Ben.Marsh
UBT: Fix multiple binaries being created if plugins specify module names more than once. MfMedia.uplugin has MfMediaFactory listed twice.
Change 3242837 on 2016/12/22 by Ben.Marsh
Change UE4EditorServices to include MacSystemIncludes rather than Cocoa.h directly; causes FVector to be defined incorrectly in non-unity builds.
Change 3242923 on 2016/12/22 by Ben.Marsh
Build: Fixes for conforming incremental workspaces:
* P4 have table is now reset before deleting all the files. This prevents Perforce being out of sync if the delete fails for some reason.
* Incremental workspaces are skipped when running a clean operation, because they do not have a workspace capture file (causing a full re-sync, always). The "P4 Clean" option is still effective for cleaning these workspaces.
Change 3242961 on 2016/12/22 by Ben.Marsh
UBT: Move entry points from PreBuildSync() and PostBuildSync() from UEToolChain to UEBuildPlatform, and make the original toolchain versions static. These functions are already at odds with the rest of the data flow within UBT because they rely on global state cached outside the toolchain instance, making assumptions that UBT is only ever going to be invoked with one target that's constructed in the same run and that nothing is being cached (eg. UBT makefiles). Moving them onto UEBuildPlatform simplifies the toolchain lifecycle for other platforms without leaving Mac and IOS any more limited than they were before.
Change 3242981 on 2016/12/22 by Ben.Marsh
UBT: Remove symbol server handling code into UAT's platform library, since it's never needed from inside UBT.
Change 3242999 on 2016/12/22 by Ben.Marsh
UBT: Remove the StripSymbols() function from the UEToolChain base class. This functionality is only required by UAT, so it's better suited to being exposed through UAT's modular platform classes.
Change 3243022 on 2016/12/22 by Ben.Marsh
UBT: Require an instance of the target rules to be able to construct a toolchain in UBT. This will allow configuring toolchain-specific options from the target, using reflection from config files, and the command line.
Change 3243083 on 2016/12/22 by Ben.Marsh
UBT: Move settings for the Windows compiler version to use onto the Windows-specific target rules.
Change 3243090 on 2016/12/22 by Ben.Marsh
UBT: Change the third party paths in UEBuildConfiguration to constants. Changing these would not work.
Change 3243423 on 2016/12/23 by Ben.Marsh
UBT: Move a lot of settings from BuildConfiguration to TargetRules. This allows different targets to have different settings, naturally, and moves converts argument parsing and config to be driven by attributes.
Change 3243516 on 2016/12/23 by Ben.Marsh
UBT: Remove the ValidateUEBuildConfiguration callback, which is no longer used. (XGE settings validation occurs in XGE.cs)
Change 3244020 on 2016/12/28 by Ben.Marsh
UBT: Remove the BaseIntermediatePath static property. Precursor to removing RelativeEnginePath and IntermediateFolder properties.
Change 3244074 on 2016/12/28 by Ben.Marsh
UBT: Remove the RelativeEnginePath variable from BuildConfiguration. UnrealBuildTool.EngineDirectory gives the absolute path, and can be used to construct a relative path when necessary.
Change 3244076 on 2016/12/28 by Ben.Marsh
UBT: Remove BuildConfiguration.BaseIntermediateFolder; just use a fixed directory everywhere instead.
Change 3244083 on 2016/12/28 by Ben.Marsh
UBT: Replace FileReference and DirectoryReference instance methods for manipulating files and directories with static methods, to mirror the System.IO.File and System.IO.Directory classes.
Change 3244441 on 2016/12/31 by Ben.Marsh
UBT: Remove code to force PDBs when building with no debug info under XGE. Verified described symptoms (that it causes PCH generation to be serialized) no longer occur.
Change 3244687 on 2017/01/03 by Matthew.Griffin
Changed Exception to use FirstInclude.IncludeName as PrecompiledHeaderIncludeFilename can be null when this occurs
Change 3246112 on 2017/01/04 by Ben.Marsh
UBT: Fix UHT failures building some targets with the -useprecompiled option, due to differences in the order that circularly dependent modules are parsed. Precompiled binaries are now kept in the regular AppBinaries list, but are excluded from the build at the last minute. Also change some checks from IsEngineInstalled() to bUsePrecompiled, to prevent headers being overwritten when running in a non-installed precompiled build.
Change 3246223 on 2017/01/04 by Ben.Marsh
UBT: Prevent version manifests being overridden if a file is not being built as part of the target.
Change 3246387 on 2017/01/04 by Ben.Marsh
UBT: Remove BuildConfiguration settings for UnrealCodeAnalyzer. This tool isn't used at the moment, but it's configured using global variables accessed from all over the UBT codebase, making it difficult to refactor the build options into an instanced object. If we bring this tool back from the dead in the future, it should be possible to implement it using the exported JSON target definition or the XGE manifest, similarly to how IncludeTool uses it.
Change 3247004 on 2017/01/04 by Ben.Marsh
UBT: Simplify the logic for cleaning targets in UBT. Now uses FileReference/DirectoryReference objects everywhere, doesn't require the compile/link environment, and does all the checking to avoid deleting precompiled binaries in one place.
Change 3247250 on 2017/01/04 by Ben.Marsh
UBT: Prevent precompiled binaries being added to the list of app binaries twice.
Change 3247594 on 2017/01/05 by Ben.Marsh
Build: Run sample and template editors on the same agents as the other incremental builds. Remove ProtoStar, which does not have any non-precompiled editor target to build.
Change 3247763 on 2017/01/05 by Ben.Marsh
UBT: Allow the toolchain to update the list of build products for each module linked into a binary. Allows Mac to add dylibs and bundle resources specified per-module without having to construct a link environment and try to link them.
Change 3247775 on 2017/01/05 by Ben.Marsh
UBT: Instance the target compile and link environments when they are required during building, and don't persist them on the UEBuildTarget instance.
Change 3247811 on 2017/01/05 by Ben.Marsh
EC: Add a batch file for testing postp filters.
Change 3247839 on 2017/01/05 by Ben.Marsh
EC: Include the name of the file being compiled when parsing MSVC errors and warnings.
Change 3248101 on 2017/01/05 by Ben.Marsh
UBT: Fix Android support for force included headers.
Change 3248533 on 2017/01/05 by Ben.Marsh
PR #3097: UBT project supports optional platforms (Contributed by PrimalJohnScott)
Change 3249205 on 2017/01/06 by Ben.Marsh
UAT: Fix ParseTaggedP4Output throwing an exception if the same key name is specified more than once. This can happen when parsing the output from "P4 INFO", where multiple brokers are present.
Change 3249249 on 2017/01/06 by Ben.Marsh
UBT: Check for the existance of AndroidManifest.xml within extracted AAR directories, rather than just checking for the existance of the directory itself. Perforce does not remove empty directories when cleaning a workspace unless the rmdir option is on the workspace, so this can cause incremental build failures to fail on build machines.
Change 3249486 on 2017/01/06 by Ben.Marsh
UBT: Use relative paths in unity files when compiling for Mac/IOS, rather than generating a separate local/remote version of the file for gathering include dependencies. Absolute paths are only used to work around the way that MSVC concatenates paths internally; we don't hit the same problems when checking dependencies.
Change 3249736 on 2017/01/06 by Ben.Marsh
UBT: Rename CPPEnvironment to CppCompileEnvironment, and remove the separate CPPEnvironmentConfiguration object. All settings are now stored directly on the CppCompileEnvironment object.
Change 3250179 on 2017/01/07 by Ben.Marsh
Fix creating installed build when root directory contains a space in the name.
Change 3250181 on 2017/01/07 by Ben.Marsh
UBT: Remove some esoteric (and unused, AFAIK) options for orthogonally building different platforms.
Change 3250223 on 2017/01/07 by Ben.Marsh
UBT: Merge the LinkEnvironment and LinkEnvironmentConfiguration classes together.
Change 3250233 on 2017/01/07 by Ben.Marsh
UGS: Allow specifying a workspace-specific sync filter, which is applied on top of the standard filter. Also fix filter being cleared if the cancel button is pressed, and help text being stripped out.
Change 3250241 on 2017/01/07 by Ben.Marsh
UBT: Move the options for specifying additional Android architectures to target onto an Android-specific object on the TargetRules.
Change 3250400 on 2017/01/08 by Ben.Marsh
UBT: Move executor config settings onto the executor instances.
Change 3257708 on 2017/01/13 by Ben.Marsh
UBT: Remove the ThirdPartySourceDirectory constant; there are many places which hard-code or assume this location anyway, and it's not going to change.
Change 3260535 on 2017/01/17 by Ben.Marsh
Add an optional "RequiredSubmittedChange" setting to EC settings files. Allows a scheduled job to run even if there have been no code changes submitted. Test with the utilization capture job.
Change 3260875 on 2017/01/17 by Ben.Marsh
EC: Fix workspaces getting out of sync wrt. newly added files when jobs are aborted during a sync. In such cases, the P4 have table indicates the new files have been synced locally, but the workspace is forced back to a state before it had them due to the capture file. When a following sync tries to add them again, P4 believes the workspace already has them synced.
To work around this, we now write an additional file to the root folder of a workspace containing the last CL that was captured, and sync back to it before doing the reconcile.
Change 3261724 on 2017/01/18 by Ben.Marsh
Allow filtering job types from the list view in EC. Hide the utilization capture job by default. Also set up notifications for the utilization capture job.
Change 3261756 on 2017/01/18 by Ben.Marsh
IncludeTool: Prevent matching a full enum declaration as a forward declaration.
Change 3261932 on 2017/01/18 by Ben.Marsh
EC: Add support for specifying days of the week in schedules. The following syntaxes are supported:
"Monday, Tuesday and Wednesday at 10:30"
"Daily except Sunday and Wednesday at 14:30"
Also tweak display of dates relative to now to handle dates/times in the future, and include the date when specifying a day name.
#jira UEB-729
Change 3262676 on 2017/01/18 by Ben.Marsh
UBT: Split UBTMakefile into its own file. (From PR #3106)
Change 3263893 on 2017/01/19 by Ben.Marsh
UBT: Stop exporting platform classes from UBT, as well as all the referenced classes that have to be made public as a result. Any platform-specific functionality that needs to be shared with UAT is now exposed through wrappers in separate public classes, eg. WindowsExports.cs, IOSExports.cs, etc...
Change 3264291 on 2017/01/19 by Ben.Marsh
UBT: Fix errors generating documentation in UBT, and enable it by default. Will catch more errors with new code being added. Originally in PR #3106, but redone due to conflicts.
Change 3264534 on 2017/01/19 by Ben.Marsh
UBT: Include plugin config files in generated projects.
Change 3264571 on 2017/01/19 by Ben.Marsh
UBT: Prevent overwriting .modules files if nothing has changed. On builders, it's common to build multiple editors in the same workspace, and changing the last modified timestamp causes BuildGraph to fail due to tampered files.
Change 3265745 on 2017/01/20 by Ben.Marsh
UGS: Automatically open UGS when running the launcher for a second time, rather than prompting to close the original instance.
Change 3265777 on 2017/01/20 by Ben.Marsh
UGS: Automatically close and reopen when UGS is re-ran with the shift key held down to switch into unstable mode.
Change 3268314 on 2017/01/23 by Ben.Marsh
UBT: Make sure version manifests are stable by sorting the list of build products, so they are only touched if the contents have really changed.
Change 3269601 on 2017/01/24 by Ben.Marsh
UBT: Fix symbol files being added to manifest for some platforms even though debug info is disabled.
Change 3269607 on 2017/01/24 by Ben.Marsh
UBT: Fix bug where UBT would need to be invoked when switching between two editors sharing the same engine binaries on Mac. The location of the .modules file cannot be guessed on Mac by looking in the same directory as the primary output executable because it's an .app bundle, and the actual modules are nested several directories below that.
Change 3269608 on 2017/01/24 by Ben.Marsh
UBT: Fix additional files copied into the app bundle always being updated on Mac. Now uses rsync --checksum to make sure only modified files are updated.
Change 3271062 on 2017/01/24 by Ben.Marsh
UBT: Fixes for bugs detected by PVS Studio (PR #3161)
Change 3272421 on 2017/01/25 by Ben.Marsh
Fix commends regarding DDC in BaseEngine.ini
#jira UE-41076
Change 3272810 on 2017/01/25 by Ben.Marsh
Fix VS2017 being displayed as 'Visual Studio 15' in the Windows target settings panel.
Change 3272935 on 2017/01/25 by Ben.Marsh
Fix Metal errors launching on Mac due to use of OSX environment settings before they are initialized. Toolchain settings are now constructed on demand in a separate class, for Mac, iOS and TVOS.
Change 3274167 on 2017/01/26 by Ben.Marsh
Fix resource files not being compiled in installed builds on Windows. Was causing metadata not to be embedded into executables.
#jira UE-36457
Change 3275557 on 2017/01/27 by Ben.Marsh
Expand checks for propagation of restricted folder names to include source files, and to ensure that each restricted folder is represented in the output. Also improve messaging to show the dependency chain leading to a restricted folder being referenced, and which folder it is.
Change 3275628 on 2017/01/27 by Ben.Marsh
UBT: Splitting configuration files into one class per-file.
Change 3276784 on 2017/01/29 by Ben.Marsh
Add an authoritative list of confidential folder names, and expose it through global BuildGraph properties ($(RestrictedFolderNames) and $(RestrictedFolderFilter)). Also switch existing scripts to use it.
Change 3276792 on 2017/01/29 by Ben.Marsh
UBT: Use UE4CSharp.prog files to indicate which projects should be included in the solution without having to hard-code a list of them in UBT.
Change 3277263 on 2017/01/30 by Ben.Marsh
IncludeTool: Merging various fixes.
* Fix warnings about #include directives after first code block from parsing monolithic headers.
* Fix exception on startup if the intermediate directory does not already exist.
* Add a special case for ignoring missing header guards from MonolithicHeaderBoilerplate.h, rather than marking it as an inline header. Marking it as inline prevents parsing include directives, which results in including CoreTypes.h from the wrong location.
* Create job objects for spawned compiler instances to prevent them trying allocating more memory than the system can spare.
* Remove (unused) code which makes assumptions about files ending with "Classes.h".
* Add a verbose per-file output log to aid with debugging.
* Negate the MakeStandalone command line option, which was added to allow tweaking forward declarations in already optimized files, so the optimized output does not have missing headers by default.
* Fix missing headers when creating standalone files, due to incorrect list of previous files being passed in to the OutputFile constructor. Now passes the original list of included files, not the output list.
* Fix initial header for a cpp file sometimes being removed. Forcibly including a header at the start of the file does not use the normal pathway for spidering through includes, so a second include of the same file was being generated. Any includes of that header were being forced into output, and the earlier include was then removed due to being redundant.
* Prevent forward declaring enums which have to be parsed by UHT. UHT relies on includes to determine a parse order, and will fail if the enum definition has not been parsed first.
* Use a relative path for private includes in the same module if there are any. Fixes some incorrect paths, and makes it clearer that we're doing something we shouldn't.
Change 3277307 on 2017/01/30 by Ben.Marsh
UBT: Fix private PCHs not using correct header. Causes custom definitions to be excluded from the command line.
[CL 3278101 by Ben Marsh in Main branch]
- Window menu is now sectioned and labeled based on the current editor. There's now a local workspace root member in FTabManager and a workspace category in FAssetEditorToolkit (both are FWorkspaceItem objects). Individual editors attach their local category to the tab manager's local root. Workflow app modes have their own category members that are swapped out when the mode changes.
- Finally, the AssetEditorCategory of FWorkspaceMenuStructure has been removed entirely.
- Replaced the AddMenuSeparator() call in FTabManager::PopulateSpawnerMenu_Helper() with a section of the same title as the workspace category.
- Tab spawner menu entries for the local editor now properly show the icon of the associated tab. To accomplish this it was necessary to change FWorkflowTabFactory::TabIcon to be an FSlateIcon instead of an FSlateBrush*. All factory instances have been updated accordingly.
- Added & updated lots of icons! (those missing will be TTP'd)
- The nomad tab spawner section (named "General" in the menu) has been largely compressed into the Developer Tools submenu, which has also been organized into sections for readability.
- Unreal frontend options were also moved into a context menu within the General section
- Moved all experimental tools to their own section of the Window menu. When they're no longer experimental they should register as nomads in the appropriate category
- Undo history now under Edit menu
[CL 2324285 by Dan Hertzka in Main branch]
TTP# 337136 - SETTINGS: Target Platform settings polish
TTP# 337652 - EDITOR: Limit Project supported Android icons down to 1
TTP# 337650 - EDITOR: There is only 1 icon for Apple for Project Supported Platforms
DesktopPlatform now contains a static array of FPlatformInfo. This can be used to query UE4 about its available platforms, even when they're not available as a target platform.
FPlatformInfo contains the information required by the editor (such as a localized display name and icon), as well as whether a platform is a variation ("flavor") of another, and if so, whether the flavor affects the build output (eg, Win32 or Win64), or the cook output (eg, Android_XYZ). This lets the editor build up nested menus for the "Package Project" and "Cook Project" options, rather than just showing everything as a flat list.

[CL 2095796 by Jamie Dale in Main branch]
Other Updates:
- The WidgetReflector is now in its own module as well. It will be converted to a plug-in later.
- The Public API of both Slate and SlateCore has largely been reorganized for better discoverabilty. More cleanup work is needed.
- Added a lot of missing API documentation and fixed existing ones. More and better documentation is needed.
- Removed dead code, fixed a couple things I stubled upon, and conformed to coding guidelines (NULL vs nullptr, line breaks, etc.)
Upgrade Notes:
- The Slate Remote Server is currently disabled - will be re-enabled shortly!
- If your module previously had a module dependency to 'Slate', it now also needs a PrivateModuleDependency to 'SlateCore' in its Build.cs file.
- If your module exposes in any of its Public header files types that are now declared in SlateCore, it needs a PublicModuleDependency to 'SlateCore'
- The ToolTip property type on SWidget has changed from SToolTip to IToolTip; change local variables to TSharedPtr<IToolTip> instead of TSharedPtr<SToolTip> where needed
- IToolTip is not a widget. If you need access to the actual widget that represents the tool tip, use IToolTip::AsWidget(); If you need access to the tool tip's content, use IToolTip::GetContentWidget()
Troubleshooting:
- After syncing to this changelist you may have to clean your /Engine/Intermediate/Build/ directory and rebuild your entire project
- If in your project you are getting linker errors for unresolved types that are now declared in SlateCore, you may be missing a dependency to 'SlateCore'
- If in the Engine code you are getting linker errors for unresolved types that are now declared in SlateCore, you may need to rebuild the entire Engine
