Posix rename support #152

Closed ghost closed 4 years ago

ghost commented 4 years ago

Hi

Could you please add support for posix rename (posix-rename@openssh.com extension)? It would allow renaming a file even if a destination already exists in one operation and without any additional steps.

Thanks.

Unfortunately, even though this feature is defined in the latest SFTP RFC, it looks like this operation isn't supported in many SFTP implementations. As a result, many SFTP clients revert to an exist check, followed by a possible delete request, followed by a rename request. See Cyberduck for one such implementation.

Support for the OpenSSH rename extension already exists via sftp.ext_openssh_rename().
