2015-01-23 13:51:42 Jorge Morais attachment added Small program that detects ctime change after rename https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1413978/+attachment/4304322/+files/rename_updates_mtime.c
2015-01-23 13:54:03 Jorge Morais description glibc manual (both in the glibc included with Ubuntu 14.10 and also in upstream glibc from git at 2014-01-23 ) at 14.9.9 File Times says: "Renaming a file with 'rename' affects only the attribute change time and modification time fields of the two parent directories involved, and not the times for the file being renamed." But in practice (tested on Ubuntu 14.10) renaming a file does change its ctime. I have checked it both at the command line and also with the small program I will attach.
