Hello,

I was sent here from the IRC channel.


Using git 2.1.0, the command

  git clone ssh://[2001:db8::1]/repo.git

succeeds, but adding a username to the URL like this

  git clone ssh://user@[2001:db8::1]/repo.git

fails with an invalid hostname message:

Cloning into 'repo.git'...
ssh: Could not resolve hostname [2001: Name or service not known
fatal: Could not read from remote repository.


I found this workaround:

  git clone ssh://[user@2001:db8::1]/repo.git

but this seems to be contrary to the definition of URLs in RFC 3986.

http://tools.ietf.org/html/rfc3986


Please have a look at this. Thank you!

This is indeed a bug.
We handle literal IPv6 adresses OK, we handle ssh://user@host OK.
But it seems as if you are the first one using the combination of both,
thanks for the bug report.

If somebody want to have a look in the Git source tree:
connect.c, t/t5500-fetch-pack.sh and t/t5601-clone.sh may deserve an update.
