Subject svn commit: r1717759 - /subversion/branches/ra-git/subversion/libsvn_fs_git/git-revroot.c
Date Thu, 03 Dec 2015 13:13:47 GMT
Author: rhuijben

New Revision: 1717759

URL: http://svn.apache.org/viewvc?rev=1717759&view=rev
Log:
On the ra-git branch: Following up on r1717667, resolve a possible segfault
and handle a few more cases of node relations.

* subversion/libsvn_fs_git/git-revroot.c
  (fs_git_node_relation): Handle same path, same rev directly. Revert reverse
    ordering of two ifs as that removed a NULL check.
