tools/glusterfind: RENAME and MODIFY issues
If Modification happens before RENAME, GFID to Path Conversion converts it into New Path. Delete Modify Entry and insert again So that MODIFY <NEW NAME> comes after RENAME. Default value of pgfids and basenames changed to "" instead of NULL Also fixed RENAME issue of displaying "RENAME <NEW NAME> <NEW NAME>". Also fixed RENAME followed by missing MODIFY Change-Id: I8202f6e6ec33f7bd921e71da38677f2ee2dab87a BUG: 1236270 Signed-off-by: Kotresh HR <khiremat@redhat.com> Signed-off-by: Milind Changire <mchangir@redhat.com> Reviewed-on: http://review.gluster.org/11443 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Aravinda VK <avishwan@redhat.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org>
