svn commit: r1703327 - in /subversion/branches/1.9.x: ./ STATUS subversion/svnfsfs/stats-cmd.c subversion/tests/cmdline/svnfsfs_tests.py

Author: svn-role
Date: Wed Sep 16 04:00:23 2015
New Revision: 1703327

URL: http://svn.apache.org/r1703327
Log:
Merge the r1698312 group from trunk:

 * r1698312, r1702310
   Correctly report empty representations in 'svnfsfs stats'.
   Justification:
     The current code displays the "0" bracket in histograms as
     "-2147483648 .. < 1" instead of "0 .. < 1".  Technically correct
     but annoying.  UI change only.
