amend the code to handle singleton comparisons properly so it only checks if they only refer to the same object or not, and not bother comparing the values.

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"
