SFTP - support path transformation for host running OpenSSH on Windows

Current Situation

• OpenSSH Server for Windows offers two options for configuration: a) Windows style connections and b) Cygwin style connections.
  • When used with Cygwin style connections then YADE will work.
  • When used with Windows style connections then this allows clients to use a path syntax such as /C:/tmp/file.txt
    • This syntax is not supported by YADE.
    • YADE will find the files with such a path, but transfers them as 0 bytes files.

Desired Behavior

• When used with Windows style connections then a Windows path, e.g. C:\tmp\file.txt, should be transformed to use forward slashes and should be prepended a leading slash as in /C:/tmp/file.txt.

Test Instructions

• use OpenSSH on Windows
• use attached TEST-YADE-OpenSSHWindows.xml configuration
  • adjust the SSHAuthentikation and the directory paths

Workaround

• For a path C:\tmp\folder on the SSH Server specify /tmp/folder or \tmp\folder with your YADE configuration.
• For use of other drives such as D:, E:, create a virtual path in your OpenSSH Server, e.g. “d = D:\” then in YADE the configuration would be /d/tmp for a path D:\tmp
