Change 2830613 on 2016/01/15 by John.Barrett
Added better ability for unit tests to test socket-level netcode
Full changes:
- Added flag for auto-reconnecting on connection close
- Added hook for socket level sends
- Added ability to block socket-level sends and pre-PacketHandler LowLevelSend's
- Added ability for net connections to force-enable packet handlers, even if presently off in the engine
#rb none
Change 2830617 on 2016/01/15 by John.Barrett@JC2Q-LT_UE4
Enabled NetcodeUnitTest in Linux, and other minor updates.
#rb none
Change 2830621 on 2016/01/15 by John.Barrett@JC2Q-LT_UE4
Added 'PacketLimitTest' and 'PacketLimitTest_Oodle' unit tests, for testing/verifying that MaxPacket limits are respected, through testing with Bunches and with raw sends passed through PacketHandlers (such as Oodle).
#rb none
Change 2832402 on 2016/01/18 by Bart.Bressler@bart.bressler_Dev_Networking
Always use the physical platform file when writing out steam_appid.txt, because it has to live next to executable that's being run (CotF builds will output it to the wrong location).
#rb josh.markiewicz
#tests checked that steam_appid.txt was written to the correct place with both CotF and cooked builds
Change 2833728 on 2016/01/19 by Joe.Conley@Joe.Conley_EGJWD5708_Dev-Networking-Minimal
Fix for UE-20017 - "Http server headers implemented as TMaps and are overridden". Just changing TMaps to TMultiMaps. Haven't modified the behavior of GetHeader(), which will still return the first header that matches.
Change 2844880 on 2016/01/26 by Joe.Conley
Fix for UE-20017 Http server headers implemented as TMaps and are overridden
Previously had submitted a fix that changes the request and response headers TMap into a MultiMap, but the consensus was that it would be better to leave them as TMaps, but allow appending onto the existing entry for a given request header with an "AppendToHeader" function, and to concatenate entries for the same header name in the response headers. In both cases, entries for the same header name are concatenated with ", ".
Mac and iOS already had the desired behavior for responses, just added the AppendToHeader function to their request classes.
HTML5 still has no implementation of response headers, filed as separate JIRA issue UE-26047.

Change 2859343 on 2016/02/08 by Bart.Bressler
Default MaxSearchResults in FOnlineSessionSearch objects to 1 instead of 0 - otherwise, the FOnlineAsyncTaskSteamFindServerBase tasks will complete right away without searching for sessions. Also print a warning in the task if this will happen.

Change 2862352 on 2016/02/10 by Bart.Bressler
Fix demo.SkipTime cvar to work with negative values
#rb john.pollard
Change 2866624 on 2016/02/14 by John.Barrett
Fix plugin commandlet crash.
#rb none
Change 2866627 on 2016/02/14 by John.Barrett
Added NetDriver/PacketHandler ability to send/receive connectionless packets - i.e. packets not associated with a UNetConnection.
Removed 'bEnabled' from PacketHandler - PacketHandler is now a default always-on part of the Engine.
Added 'CountBits' to LowLevelSend, to support bit-level additions to packets from PacketHandler's, and refactored related code.
#codereview John.Pollard
Change 2866628 on 2016/02/14 by John.Barrett
Added an HMAC (Hash-based Message Authentication Code) generating function, to the SHA-1 code - for use with performing secure net connection handshakes.
#rb none
Change 2866629 on 2016/02/14 by John.Barrett
Added 'stateless handshake' to UE4, allowing a handshake to be performed without any open UNetConnection - making it more difficult for DoS attacks to consume memory resources.
#codereview John.Pollard
Change 2866630 on 2016/02/14 by John.Barrett
Updated Oodle to support new stateless handshake.
#rb none
Change 2866631 on 2016/02/14 by John.Barrett
Updated NetcodeUnitTest to work with new connectionless/stateless handshake changes. Compiles, but netcode presently needs fixing.
#rb none
Change 2868367 on 2016/02/16 by John.Barrett
Updated NetcodeUnitTest to work with stateless handshakes (now fixed connecting).
Also fixed further commandlet problems.
#rb none
Change 2878025 on 2016/02/23 by John.Barrett
Immediately stop processing zero-size packets, to prevent CPU utilization during DDoS.
Log IP of new connections, post-stateless-challenge (first time we know IP is verified).
#codereview john.pollard
Change 2883776 on 2016/02/26 by John.Barrett
Fixed beacons to work with stateless handshake.
Change 2886773 on 2016/02/29 by John.Barrett
Made PacketHandler bit overhead align upwards to the next byte - this wastes more bits than necessary, but is required as a temporary fix.
Change 2887801 on 2016/03/01 by John.Pollard
Use correct default values when initializing shadow state for replication.
Fixes issues with certain components and actors that have default values that differ from CDO.

MAJOR FEATURES + CHANGES
==========================
Change 2718441 on 2015/10/06 by Ben.Marsh@Ben.Marsh_T3245_Stream
Allow nodes to be added with an "explicit" frequency, meaning that they'll only be part of manually triggered builds (not CIS).
Change 2718698 on 2015/10/06 by Ben.Marsh@Ben.Marsh_T3245_Stream
Add a type of node that can execute an arbitrary sequence of tasks, and allow constructing graphs of such nodes from an XML file.
Change 2723013 on 2015/10/09 by Ben.Marsh@Ben.Marsh_T3245_Stream
Small utility to quickly capture a workspace, or delete files to restore the workspace to a previously captured state (and output a p4 sync list to restore it)
Change 2744521 on 2015/10/28 by Matthew.Griffin@Matthew.Griffin_G5772_BuildStream
Adding config entries to determine which platforms/configurations are available
Currently only written out as part of the Rocket Build process but could be done elsewhere for other types of installed build.
A near identical singleton class is used in both C++ and C# to load the config section and check whether configuration/platform combinations are valid.
Change 2773723 on 2015/11/19 by Ben.Marsh@Ben.Marsh_T3245_Stream
Copying UnrealGameSync into Engine/Source/Programs.
Change 2773914 on 2015/11/19 by Ben.Marsh@Ben.Marsh_T3245_Stream
PR #1687: [GitDependencies] New feature: ignore file support (.gitdepsignore) (Contributed by nbjk667)
Change 2775317 on 2015/11/20 by Ben.Marsh@Ben.Marsh_T3245_Stream
Add a -listtps option to UBT, which will find all the TPS files in any directory that's compiled into a target.
Change 2780832 on 2015/11/25 by Ben.Marsh@Ben.Marsh_T3245_Stream
Allow compiling a single file in UBT. Pass -singlefile=<Path> on command line to UBT to use.
Change 2781071 on 2015/11/25 by Ben.Marsh@Ben.Marsh_T3245_Stream
Precompile all valid engine modules for Rocket by default. Modules may set the PrecompileForTargets field to control which configurations they should be compiled for. Modules which currently fail to compile have this set to
PrecompileTargetsType.None.
#codereview Matthew.Griffin
Change 2784469 on 2015/12/01 by Matthew.Griffin@Matthew.Griffin_G5772_BuildStream
Added -FastPDB commandline parameter for UBT, so that we can make use of the /DEBUG:FASTLINK option in VS2015
Change 2784722 on 2015/12/01 by Matthew.Griffin@Matthew.Griffin_G5772_BuildStream
Made -FastPDB option part of BuildConfiguration instead of checking commandline at each place it's used. Also added option to override if someone doesn't want it automatically added to their project files.
Change 2787501 on 2015/12/02 by Ben.Marsh@Ben.Marsh_T3245_Stream
Restore change to gather VC environment directly from registry.
