mkdir and copy interpret rel URLs differently

[andre-merzky]

f = File('ssh://stampede/work/user/out.dat')
f.copy('/tmp/data/out.dat', CREATE_PARENTS)

that code is semantically not expressing a remote transfer, as the copy target is not an abs URL, so is interpreted in the f.url context, ie. on stampede. That indeed works for the CREATE_PARENTS interpretation, but the file transfer will attempt to move the file to localhost...

Hey Andre, is this issue address in any commit or PR?

[andre-merzky]

No, this is still open. We work around this by always using full URLs, but that behavior is surprising (to say the least) for unsuspecting users and needs fixing.

For the example above, I think I would have expected the output to be copied to localhost and not on Stampede, FWIW :) But I mostly personally prefer full URLs wherever possible.

Well, the holy SAGA spec says otherwise ... ;-)

Alrighty! Leaving this ticket open in that case.
