create repo from svn-cloned git repo fails on push

[snomos]

Steps to reproduce:

1. PERL_UNICODE=D git svn clone https://gtsvn.uit.no/langtech/trunk/langs/sme --authors-file=svn2git-authors.txt lang-sme/
2. target/debug/dadmin create repo -o giellalttmp -r lang-.* -d /Users/smo036/svn2git/

The file svn2git-authors.txt is attached. /Users/smo036/svn2git/ is the local dir in which lang-sme is located. Replace with the actual path from step 1.

Step 1. stops with an error at svn rev 85005:

r85005 = 5ffc6c641376643c9feeea02a4abb3fea7e0f3ad (refs/remotes/git-svn)
tools/grammarcheckers/errordata/error-áidna.txt was not found in commit 5ffc6c641376643c9feeea02a4abb3fea7e0f3ad (r85005)

The resulting git repo still seems to be just fine (just lacking a 100k commits), and in size it should be good enough for real-world testing.

The result is the following:

$ target/debug/dadmin create repo -o giellalttmp -r lang-.* -d /Users/smo036/svn2git/

Created repo for lang-sme successfully at: https://github.com/giellalttmp/lang-sme

The reported branch is the only one it seems:

git branch -a
  remotes/git-svn

Env. info:

• latest dadmin source
• macOS 10.14.6.

svn2git-authors.txt

It seems that @albbas has had the same issue - all repos created last night are empty, which indicates that dadmin failed for him in a similar way: the repos are created, but nothing is pushed.

Issues

The reason it was failed is: dadmin tried to push all branches (include local and remote) which is wrong. Dadmin should only push local branches.

And another problem is: the lang-sme repository doesn’t have any local branch. If you use command git branch -l -which show all local branches - it will print empty line. git branch -a will show all branches both local and remote.

Solution

• For the first issue: dadmin should only push local branches.
• For second issue: dadmin should only create new repository in github if there is some local branch. If there is no branch it should show some error message instead.
