|
- fix: KcpClient.RawSend now returns if socket wasn't created yet
|
|
- fix: https://github.com/MirrorNetworking/Mirror/issues/3591 KcpPeer.SendDisconnect now rapid
|
|
fires several unreliable messages instead of sending reliable. Fixes disconnect message not
|
|
going through if the connection is closed & removed immediately after.
|
|
|
|
V1.39 [2023-10-31]
|
|
- fix: https://github.com/MirrorNetworking/Mirror/issues/3611 Windows UDP socket exceptions

|
|
- fix: #54 mismatching cookie race condition. cookie is now included in all messages.
|
|
- feature: Exposed local end point on KcpClient/Server
|
|
- refactor: KcpPeer refactored as abstract class to remove KcpServer initialization workarounds
|
|
|
|
V1.37 [2023-07-31]
|
|
- fix: #47 KcpServer.Stop now clears connections so they aren't carried over to the next session

- fix: #49 KcpPeer.RawInput message size check now considers cookie as well
|
|
- kcp.cs cleanups
|
|
|
|
V1.35 [2023-04-05]
|
|
- fix: KcpClients now need to validate with a secure cookie in order to protect against
|
|
UDP spoofing. fixes:
|
|
https://github.com/MirrorNetworking/Mirror/issues/3286
|
|
[disclosed by IncludeSec]
|
|
- KcpClient/Server: change callbacks to protected so inheriting classes can use them too
|
|
- KcpClient/Server: change config visibility to protected
|
|
|
|
V1.34 [2023-03-15]
|
|
- Send/SendTo/Receive/ReceiveFrom NonBlocking extensions.
|
|
to encapsulate WouldBlock allocations, exceptions, etc.
|
|
allows for reuse when overwriting KcpServer/Client (i.e. for relays).
|
|
|
|
V1.33 [2023-03-14]
|
|
- perf: KcpServer/Client RawReceive now call socket.Poll to avoid non-blocking
|
|
socket's allocating a new SocketException in case they WouldBlock.
|
|
fixes https://github.com/MirrorNetworking/Mirror/issues/3413
|
|
- perf: KcpServer/Client RawSend now call socket.Poll to avoid non-blocking
|
|
socket's allocating a new SocketException in case they WouldBlock.

|
|
- fix: KcpPeer RawInput now doesn't disconnect in case of random internet noise
|
|
|
|
V1.31 [2023-03-05]
|
|
- KcpClient: Tick/Incoming/Outgoing can now be overwritten (virtual)
|
|
- breaking: KcpClient now takes KcpConfig in constructor instead of in Connect.
|
|
cleaner, and prepares for KcpConfig.MTU setting.
|
|
- KcpConfig now includes MTU; KcpPeer now works with KcpConfig's MTU, KcpServer/Client
|
|
buffers are now created with config's MTU.
|
|
|
|
V1.30 [2023-02-20]
|
|
- fix: set send/recv buffer sizes directly instead of iterating to find the limit.
|
|
fixes: https://github.com/MirrorNetworking/Mirror/issues/3390
|
|
- fix: server & client sockets are now always non-blocking to ensure main thread never
|
|
blocks on socket.recv/send. Send() now also handles WouldBlock.
|
|
- fix: socket.Receive/From directly with non-blocking sockets and handle WouldBlock,
|
|
instead of socket.Poll. faster, more obvious, and fixes Poll() looping forever while
|
|
socket is in error state. fixes: https://github.com/MirrorNetworking/Mirror/issues/2733
|
|
|
|
V1.29 [2023-01-28]

https://github.com/MirrorNetworking/Mirror/issues/3361
|
|
|
|
V1.27 [2023-01-08]
|
|
- KcpClient.Connect: invoke own events directly instead of going through peer,
|
|
which calls our own events anyway
|
|
- fix: KcpPeer/Client/Server callbacks are readonly and assigned in constructor
|
|
to ensure they are safe to use at all times.
|
|
fixes https://github.com/MirrorNetworking/Mirror/issues/3337
|
|
|
|
V1.26 [2022-12-22]
|
|
- KcpPeer.RawInput: fix compile error in old Unity Mono versions
|
|
- fix: KcpServer sets up a new connection's OnError immediately.

fixes KcpPeer throwing NullReferenceException when attempting to call OnError
|
|
after authentication errors.
|
|
- improved log messages
|
|
|
|

|
|
- breaking: removed where-allocation. use IL2CPP on servers instead.
|
|
- breaking: KcpConfig to simplify configuration
|
|
- high level cleanups
|
|
|
|
V1.24 [2022-12-14]

|
|
|
|
V1.23 [2022-12-07]
|
|
- KcpClient: rawReceiveBuffer exposed
|
|
- fix: KcpServer RawSend uses connection.remoteEndPoint instead of the helper
|
|
'newClientEP'. fixes clients receiving the wrong messages meant for others.
|
|
https://github.com/MirrorNetworking/Mirror/issues/3296
|
|
|
|
V1.22 [2022-11-30]
|
|
- high level refactor, part two.
|
|
|
|
V1.21 [2022-11-24]
|
|
- high level refactor, part one.
|
|
- KcpPeer instead of KcpConnection, KcpClientConnection, KcpServerConnection
|
|
- RawSend/Receive can now easily be overwritten in KcpClient/Server.
|
|
for non-alloc, relays, etc.
|
|
|
|
V1.20 [2022-11-22]
|
|
- perf: KcpClient receive allocation was removed entirely.
|
|
reduces Mirror benchmark client sided allocations from 4.9 KB / 1.7 KB (non-alloc) to 0B.
|
|
- fix: KcpConnection.Disconnect does not check socket.Connected anymore.
|

|
|
V1.19 [2022-05-12]
|
|
- feature: OnError ErrorCodes
|
|
|
|
V1.18 [2022-05-08]
|
|
- feature: OnError to allow higher level to show popups etc.
|
|
- feature: KcpServer.GetClientAddress is now GetClientEndPoint in order to
|
|
expose more details
|
|
- ResolveHostname: include exception in log for easier debugging
|
|
- fix: KcpClientConnection.RawReceive now logs the SocketException even if
|
|
it was expected. makes debugging easier.
|
|
- fix: KcpServer.TickIncoming now logs the SocketException even if it was
|
|
expected. makes debugging easier.
|
|
- fix: KcpClientConnection.RawReceive now calls Disconnect() if the other end
|
|
has closed the connection. better than just remaining in a state with unusable
|
|
sockets.
|
|
|
|
V1.17 [2022-01-09]
|
|
- perf: server/client MaximizeSendReceiveBuffersToOSLimit option to set send/recv
|
|
buffer sizes to OS limit. avoids drops due to small buffers under heavy load.
|
|
|
|
V1.16 [2022-01-06]
|
|
- fix: SendUnreliable respects ArraySegment.Offset
|
|
- fix: potential bug with negative length (see PR #2)
|
|
- breaking: removed pause handling because it's not necessary for Mirror anymore
|
|
|
|
V1.15 [2021-12-11]
|
|
- feature: feature: MaxRetransmits aka dead_link now configurable
|
|
- dead_link disconnect message improved to show exact retransmit count
|

|
- fix: perf: uncork max message size from 144 KB to as much as we want based on
|
|
receive window size.
|
|
fixes https://github.com/vis2k/kcp2k/issues/22
|
|
fixes https://github.com/skywind3000/kcp/pull/291
|
|
- feature: OnData now includes channel it was received on
|
|
|
|
V1.12 [2021-07-16]
|
|
- Tests: don't depend on Unity anymore
|
|
- fix: #26 - Kcp now catches exception if host couldn't be resolved, and calls
|
|
OnDisconnected to let the user now.
|
|
- fix: KcpServer.DualMode is now configurable in the constructor instead of
|
|
using #if UNITY_SWITCH. makes it run on all other non dual mode platforms too.
|
|
- fix: where-allocation made optional via virtuals and inheriting
|
|
KcpServer/Client/Connection NonAlloc classes. fixes a bug where some platforms
|
|
might not support where-allocation.
|
|
|
|
V1.11 rollback [2021-06-01]
|
|
- perf: Segment MemoryStream initial capacity set to MTU to avoid early runtime
|
|
resizing/allocations
|
|
|
|
V1.10 [2021-05-28]
|
|
- feature: configurable Timeout
|
|
- allocations explained with comments (C# ReceiveFrom / IPEndPoint.GetHashCode)
|
|
- fix: #17 KcpConnection.ReceiveNextReliable now assigns message default so it
|
|
works in .net too
|
|
- fix: Segment pool is not static anymore. Each kcp instance now has it's own
|
|
Pool<Segment>. fixes #18 concurrency issues
|
|
|
|
V1.9 [2021-03-02]
|
|
- Tick() split into TickIncoming()/TickOutgoing() to use in Mirror's new update
|
|
functions. allows to minimize latency.
|
|
=> original Tick() is still supported for convenience. simply processes both!
|
|
|
|
V1.8 [2021-02-14]
|
|
- fix: Unity IPv6 errors on Nintendo Switch
|
|
- fix: KcpConnection now disconnects if data message was received without content.
|
|
previously it would call OnData with an empty ArraySegment, causing all kinds of
|
|
weird behaviour in Mirror/DOTSNET. Added tests too.
|
|
- fix: KcpConnection.SendData: don't allow sending empty messages anymore. disconnect
|
|
and log a warning to make it completely obvious.
|
|
|
|
V1.7 [2021-01-13]
|
|
- fix: unreliable messages reset timeout now too
|
|
- perf: KcpConnection OnCheckEnabled callback changed to a simple 'paused' boolean.
|
|
This is faster than invoking a Func<bool> every time and allows us to fix #8 more
|
|
easily later by calling .Pause/.Unpause from OnEnable/OnDisable in MirrorTransport.
|
|
- fix #8: Unpause now resets timeout to fix a bug where Mirror would pause kcp,
|
|
change the scene which took >10s, then unpause and kcp would detect the lack of
|
|
any messages for >10s as timeout. Added test to make sure it never happens again.
|
|
- MirrorTransport: statistics logging for headless servers
|
|
- Mirror Transport: Send/Receive window size increased once more from 2048 to 4096.
|
|
|
|
V1.6 [2021-01-10]
|
|
- Unreliable channel added!
|
|
- perf: KcpHeader byte added to every kcp message to indicate
|
|
Handshake/Data/Ping/Disconnect instead of scanning each message for Hello/Byte/Ping
|
|
content via SegmentEquals. It's a lot cleaner, should be faster and should avoid
|
|
edge cases where a message content would equal Hello/Ping/Bye sequence accidentally.
|
|
- Kcp.Input: offset moved to parameters for cases where it's needed
|
|
- Kcp.SetMtu from original Kcp.c
|
|
|
|
V1.5 [2021-01-07]
|
|
- KcpConnection.MaxSend/ReceiveRate calculation based on the article
|
|
- MirrorTransport: large send/recv window size defaults to avoid high latencies caused
|
|
by packets not being processed fast enough
|
|
- MirrorTransport: show MaxSend/ReceiveRate in debug gui
|
|
- MirrorTransport: don't Log.Info to console in headless mode if debug log is disabled
|
|
|
|
V1.4 [2020-11-27]
|
|
- fix: OnCheckEnabled added. KcpConnection message processing while loop can now
|
|
be interrupted immediately. fixes Mirror Transport scene changes which need to stop
|
|
processing any messages immediately after a scene message)
|
|
- perf: Mirror KcpTransport: FastResend enabled by default. turbo mode according to:
|
|
https://github.com/skywind3000/kcp/blob/master/README.en.md#protocol-configuration
|
|
- perf: Mirror KcpTransport: CongestionControl disabled by default (turbo mode)
|
|
|
|
V1.3 [2020-11-17]
|
|
- Log.Info/Warning/Error so logging doesn't depend on UnityEngine anymore
|
|
- fix: Server.Tick catches SocketException which happens if Android client is killed
|
|
- MirrorTransport: debugLog option added that can be checked in Unity Inspector
|
|
- Utils.Clamp so Kcp.cs doesn't depend on UnityEngine
|
|
- Utils.SegmentsEqual: use Linq SequenceEqual so it doesn't depend on UnityEngine
|
|
=> kcp2k can now be used in any C# project even without Unity
|
|
|
|
V1.2 [2020-11-10]
|
|
- more tests added
|
|
- fix: raw receive buffers are now all of MTU size
|
|
- fix: raw receive detects error where buffer was too small for msgLength and
|
|
result in excess data being dropped silently
|
|
- KcpConnection.MaxMessageSize added for use in high level
|
|
- KcpConnection.MaxMessageSize increased from 1200 bytes to to maximum allowed
|
|
message size of 145KB for kcp (based on mtu, overhead, wnd_rcv)
|
|
|
|
V1.1 [2020-10-30]
|
|
- high level cleanup, fixes, improvements
|
|
|
|
V1.0 [2020-10-22]
|
|
- Kcp.cs now mirrors original Kcp.c behaviour
|
|
(this fixes dozens of bugs)
|
|
|
|
V0.1
|
|
- initial kcp-csharp based version |
