Description

To reproduce

set system config-management commit-archive location 'scp://test123:foo%bar12/[email protected]/config/tftpboot'

The password / is treated wrongly and generates:

VyOS 1.3 equuleus

[email protected]# commit
Archiving config...
  scp://test123:foo%bar12/[email protected]/config/tftpboot Traceback (most recent call last):
  File "<string>", line 1, in <module>

VyOS 1.4 sagitta

[email protected]# set system config-management commit-archive location 'scp://test123:foo%bar12/[email protected]/config/tftpboot'

  "//test123:foo%bar12/[email protected]/config/tftpboot" is not a valid URI for the scp URL scheme


  Invalid value
  Value validation failed
  Set failed

I do not know which one is more bad, at least the 1.4 error will generate errors during image upgrades as now the validator fails

After some research, I have concluded that the error was caused by the string's violation of RFC 3986, which recommends using percent encoding instead. I'll look into the feasibility of implementing percent encoding/decoding (which urllib natively supports) for spicy characters if there's demand, but the recommended method in VyOS right now is using the protocol-agnostic REMOTE_USERNAME and REMOTE_PASSWORD environment variables, which bypass the URL decoding step. The alternative would involve messing with urllib.parse's internal parser to implement a laxer and less greedy regexp to accept passwords like this, which is probably a bad idea.
