Problems with git-svn authors file

hello,

i tried to use git-svn with author-files and got stuck with following error message:

Use of uninitialized value in hash element at /usr/bin/git-svn line
2952.
Use of uninitialized value in concatenation (.) or string at
/usr/bin/git-svn line 2953.
Author:  not defined in .git/info/svn-authors file
512 at /usr/bin/git-svn line 457
        main::fetch_lib() called at /usr/bin/git-svn line 328
        main::fetch() called at /usr/bin/git-svn line 187

my svn-authors file looks like this: ---->8----------------- username = Real Name <email@address> ---->8----------------- It is placed in .git/info/svn-authors and is configured via svn.authorsfile. I tried to dig in the code and it says at line 2952 if there is an $_author variable defined and no $users{$author}, then die with that message... 

above function load_authors i have found
# '<svn username> = real-name <email address>' mapping based on git-svnimport:

now i am a bit confused, because the manual says, the svn-authors file looks like my file above and here it sounds like 

<svn username> = real-name <email address>
is the real syntax for that file...

If i ommit the -A or --authors-file= parameter (or unset the svn.authorsfile config-parameter) while git-svn fetch, afterwards in gitk --all, there is only the svn-username and the revision-uuid.

Am i doing something wrong?
Sincerly

I've had errors like this. For certain repositories (possibly very old ones) there is an unusual, empty, revision 0. I got around the problem by telling git-svn to start at revision 1. Everything seemed fine after that.

$ git-svn fetch -r1
I don't know if that will be your fix, but it's worth a try.

Well it is a fresh repository. And you are right, there is an empty revision 0. I didn't recognize that is was the revision 0 I got stuck with. But it is obvious now :)

That fixed it, thx.

No, this is just a bug in git-svn.

After the following patch, you should be able to use -------------------------------------------- (no author) = real-name <email address> -------------------------------------------- in your authors file.

Subject: [PATCH] git-svn: correctly handle "(no author)" when using an authors file

The low-level parts of the SVN library return NULL/undef for
author-less revisions, whereas "(no author)" is a (svn) client
convention.
