There are much better ways to handle this and most editors shouldn't need this in modern times, drop the noise from the files. Its not consitently applied anyway. (Bitbake rev: 5e43070e3087d09aea2f459b033d035c5ef747d0) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

BitBake SFTP Fetch implementation
|
|
|
|
Class for fetching files via SFTP. It tries to adhere to the (now
|
|
expired) IETF Internet Draft for "Uniform Resource Identifier (URI)
|
|
Scheme for Secure File Transfer Protocol (SFTP) and Secure Shell
|
|
(SSH)" (SECSH URI).
|
|
|
|
It uses SFTP (as to adhere to the SECSH URI specification). It only
|
|
supports key based authentication, not password. This class, unlike
|
|
the SSH fetcher, does not support fetching a directory tree from the
|
|
remote.

|

|
|
https://tools.ietf.org/html/draft-ietf-secsh-filexfer-13
|
|
|
|
Please note that '/' is used as host path seperator, and not ":"
|
|
as you may be used to from the scp/sftp commands. You can use a
|
|
~ (tilde) to specify a path relative to your home directory.
|
|
(The /~user/ syntax, for specyfing a path relative to another
|
|
user's home directory is not supported.) Note that the tilde must
|
|
still follow the host path seperator ("/"). See exampels below.
|
|
|
|
Example SRC_URIs:
|
|
|
|
SRC_URI = "sftp://host.example.com/dir/path.file.txt"
|
|
|
|
A path relative to your home directory.
|
|
|
|
SRC_URI = "sftp://host.example.com/~/dir/path.file.txt"
|
|
|
|
You can also specify a username (specyfing password in the
|
|
URI is not supported, use SSH keys to authenticate):
|
|
|
|
SRC_URI = "sftp://user@host.example.com/dir/path.file.txt"
