Fail on old repository

[stoune]

I have quite large repository. When I'm exporting to git from hg I'm receiving error:

master: Exporting thorough delta revision 2804/4207 with 0/23/1 added/changed/removed files
Traceback (most recent call last):

I'm used following options:

Duplicate of #34

@frej This is not a duplicate of #34 . If you look at the call stack here, sanitize_name is not being called at all. I am experiencing this issue as well and will provide a pull request if I can.

I just ran into this with one of my projects. Same stack trace with export_file_contents, etc. No sanitize_name in the stack.

In my case the crash was occuring in fast import because one of my branch names was problematic, even after being sanitized by sanitize_name. The imported repository had a branch named erroneously after a whole ssh:// URL, so something like:

ssh://daniel@where-ever.com/repos/something

The branch name was sanitized to replace the colon, but apparently the "/" also causes problems. I'll submit a pull request with a tweak to add / to the regex for sanitizing. This worked around the issue for me.

Anybody else who comes across this issue, the right solution is to use the branch renaming -B flag to alleviate any problems that may be occurring because of the old Mercurial branch names. See explanation on #285.
