Bug 735658

Can you reproduce this - consistently?

Is there any special network components (firewalls) that block the connection?

..sad, yes sometimes my ISP block this site.. but before version I can hg pull && hg update from google code,,
this site url is about ipv6 hosts.

/usr/lib64/python2.7/site-packages/mercurial/ssl.py

We have seen a similar report from a Chinese user.

This error "can't happen". It seems to be a bug in Python, but we need to understand the bug in order to correctly work around it.

Can you try to place the attached file in
/usr/lib64/python2.7/site-packages/mercurial/ssl.py , reproduce the problem using
  hg -v --debug ...
, show us the full output, and remove this ssl.py again?

- and what do you mean with "this site url is about ipv6 hosts"? Are you using a IPv6 system with no IPv4?

That wasn't meant literally. Run the clone command that failed, but add -v and --debug . And please show the full terminal output, including the command you run.
