* Introduced ChannelExtendedDataEventArgs which is used to signal receive of extended data.
* Removed DataTypeCode from ChannelDataEventArgs, as this is specific to extended data.
* Large set of optimizations in receive and send of SSH messages:
- removed several buffer copies
- modified most of the SSH messages to allow the size of the message to be calculated in advance to eliminate need to resize buffer.
- added Compress(byte[] data, int offset, int length) overload to Compressor to compress part of a given buffer thereby avoiding need for buffer copy.
- added Encrypt(byte[] data, int offset, int length) overload to Cipher to encrypt part of a given buffer thereby avoiding need for buffer copy.
* SshData:
- SshData.GetBytes uses a SshDataStream which has a capacity that (in almost all cases) matches the size of the SSH message.
- Added a Load(byte[] value, int offset) overload.
- Added a LoadBytes(byte[] bytes, int offset) overload.
- Added a Write(byte[] data) overload.
- Added a Write(byte[] buffer, int offset, int count) overload.
* Added SendData(byte[] data, int offset, int size) overload to Channel to allow sending part of a given buffer.
This avoids a buffer copy in ScpClient, SftpClient, Shell, ChannelDirectTcpip, ChannelForwardedTcpip.
Fixes issue #1516.
All optimization changes above are only active when the TUNING conditional compilation symbol is defined.
By default, this symbol is defined.
