Conflicting % symbol in string with error_rule function of rules.py

[yichoe]

% symbol in string causes error in error_rule function of rules.py.

It happens when roswtf checks IP address. The IPv6 uses a zone index to provide routing information. The zone index is appended to the address, separated by '%'. This notation causes syntax conflict with Python when roswtf deals with it.

In case of URI, they are finding solution to avoid syntax conflict like here:

http://tools.ietf.org/html/draft-fenner-literal-zone-02

I think there are two ways to resolve it;

(1) Avoid substitution by dictionary in rules.py when checking local network configuration, because this substitution by dictionary doesn't affect results.
(2) Return IP address information in network.py after replacing '%' symbols in IPv6 address by '/' like ubuntu.

That document isn't english! I don't understand a thing...

I think I like 2) better. It's common in python and cmake to convert unconvential windows characters (like slashes) to unix equivalents.

Does it actually break anything else by converting to /? e.g. who uses that data after you converted?

[yichoe]

Strange.. I can see english from that link.

Since only roswtf refers roswtf\network.py, I think it will not make trouble to others although % is converted to / in roswtf\network.py.

Yeah, it's english, but its lawyer speak. Illegible!

Just for the record, examples of the differing formats are like:
