From 723b7a2789d66c1365390cc9b9213e34ab8513d7 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Fri, 10 Dec 2010 04:00:55 -0600 Subject: [PATCH] vcs-svn: eliminate repo_tree structure Rely on fast-import for information about previous revs. This requires always setting up backward flow of information, even for v2 dumps. On the plus side, it simplifies the code by quite a bit and opens the door to further simplifications.
