svn commit: r1186359 - in /subversion/branches/1.7.x: ./ STATUS subversion/libsvn_fs_fs/fs_fs.c subversion/libsvn_fs_fs/tree.c subversion/libsvn_fs_fs/tree.h

Author: hwright
Date: Wed Oct 19 17:28:55 2011
New Revision: 1186359

URL: http://svn.apache.org/viewvc?rev=1186359&view=rev
Log:
Merge r1186121, r1186231 from trunk:

 * r1186121, r1186231
   FSFS: Fix validation so it doesn't hork preexisting repositories that
   triggered a bug once in their history.
   Justification:
     Such repositories are unusable by 1.7.x without this revision.
     Either this must be backported to 1.7.1 or r1186144 must be undone.
