New Revision: 1494913
URL: http://svn.apache.org/r1494913
Log:
Fix a severe performance regression in 'svn log': The new log code
will run svn_client__repos_location_segments even if we log on the
root folder. That triggered a long-standing performance issue in
fs_node_origin_rev. This patch fixes the latter.
* subversion/libsvn_fs_fs/tree.c
(fs_node_origin_rev): special case root node IDs instead of walking
