Re: Problem with git-svn

I'm having a problem with git-svn.  I was connecting to a remote svn
repository via the svn+ssh:// protocol using an embedded username in
the url, i.e svn+ssh://boazstuller@svn.example.com/some/complicated/path.
 When I upgraded to 1.6.0, 'git svn dcommit' stopped working and
instead kept asking me for a password.   I tracked the problem down to
the following commit:

    git-svn: add ability to specify --commit-url for dcommit

I don't know perl, but the problem seems to be where around line 446,
'$gs->full_url' gets changed to  '$url'.  Apparently, $gs->full_url
contained the embedded username but $url has it stripped out, i.e
svn+ssh://svn.example.com/some/complicated/path , so ssh can't tell
what username I'm trying to log in as.

Hi Boaz, thanks for tracking this down.  The following patch should
fix your issue (and another potential one I noticed).

I've lightly tested it and it appears to work for me.

Subject: [PATCH] git-svn: fix dcommit to urls with embedded usernames

Don't rely on the extracted URL from working_head_info since
that has the username removed.  Instead use the $gs->full_url
method (as before with ba24e7457aa1f958370bbb67dfb97e3ec806fd4a)
to give us the URL to commit to if --commit-url is not
specified.

Aditionally, since we clean usernames from URLs, checking the
URL after rebase can fail because it doesn't match the URL we
used to commit; so unconditionally provide a username-free
URL for checking the result of the refetch.
