Package: samba
Version: 2:3.5.11~dfsg-1~bpo60+1
Severity: important
Cached and uncached file attributes have distinct timestamps under CIFS.
Here is a way to reproduce the issue with a CIFS/ext3 export:
# touch x; ls --full-time x; sleep 1; ls --full-time x
-rw-rw-rw- 1 atn atn 0 2011-08-26 13:32:13.330511809 +0200 x
-rw-rw-rw- 1 atn atn 0 2011-08-26 13:32:13.000000000 +0200 x
^^^^^^^^^
If I run the same CIFS configuration with an ext4 filesystem, the timestamps are
now almost the same but there is still a 67ns difference:
# touch x; ls --full-time x; sleep 1; ls --full-time x
-rw-rw-rw- 1 atn atn 0 2011-08-26 14:02:23.511864967 +0200 x
-rw-rw-rw- 1 atn atn 0 2011-08-26 14:02:23.511864900 +0200 x
^^
On a ext4 FS without CIFS, it just works:
# touch x; ls --full-time x; sleep 1; ls --full-time x
-rw-r--r-- 1 cyb cyb 0 2011-08-26 14:25:42.311759806 +0200 x
-rw-r--r-- 1 cyb cyb 0 2011-08-26 14:25:42.311759806 +0200 x
Timestamps should remain the same whatever the cache status is. It breaks many
applications like Emacs, Gedit, Eclipse because they complain about file
modifications.
This is closely related to http://bugs.debian.org/366940 but not the same, it's
rather quite the opposite.
Same issue with samba/squeeze and samba/squeeze-backports.
Would it be possible to fix it?
