The output of runfetchcmd is always empty in this case, as the test doesn't produce any output. SSH either returns 0 or 1, which is handled via exceptions. This means the current check is not only unnecessary but prevents the function from working. We can just assume that if we reach the end of the function that the file exists and return True.

BitBake 'Fetch' implementations
|
|
|
|
This implementation is for Secure Shell (SSH), and attempts to comply with the
|
|
IETF secsh internet draft:
|
|
http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
|
|
|
|
Currently does not support the sftp parameters, as this uses scp
|
|
Also does not support the 'fingerprint' connection parameter.
|
|
|
|
Please note that '/' is used as host, path separator not ':' as you may
|
|
be used to, also '~' can be used to specify user HOME, but again after '/'
|
|
|
|
Example SRC_URI:
|
|
SRC_URI = "ssh://user@host.example.com/dir/path/file.txt"
|
|
SRC_URI = "ssh://user@host.example.com/~/file.txt"
