Most notable for this series is adding some tests for remote-svn-alpha helper and not (over)writing refs/heads/master. The helper is able to import whole svn repository root as the only remote branch. But it doesn't reuse any previously imported data, i.e. each time whole history is imported. Also it can't yet push, and can't configure svn username other than Guest and password other than empty. Works both in git clone and git remote add & git fetch scenarios. $ git clone -b master svn-alpha::http://some.org/svnrepo "-b master" tells to use remote branch master as a local HEAD to be checked out. This is necessary because the helper can't tell git that HEAD is a "symlink" to refs/heads/master and even can't tell it's sha1 (lists it as "? HEAD") before actually importing. $ git remote add svn svn-alpha::http://some.org/svnrepo $ git fetch svn Known bugs are: 1) absolutely empty (no r1) svn repo import fails 2) git clone needs either --bare, -n or -b master The patch base is svn-fe-pu at git://repo.or.cz/git/jrn.git also a commit 7153183171de77d084a4c24ef19d23d6313ded2a can be used as an earlier patch base. For the last two commits some new svn-fe options[1] are required. Whole git-remote-svn-alpha and a test script are cited at the bottom of this letter as a quick reference for those who don't track svn-fe-pu.
