I've been using a Windoze based programming editor (Slickedit) across
samba shares for years without any problems (most recently with FC5). I've
just started using Ubuntu and I'm now having a problem with timestamps
lagging file writes. The net result is my editor almost always
thinks another program has modified the file.
Today I built and installed samba 3.3.3. from sources and it shows
the same problem.
The problem is easy to demonstrate with a batch file:
---
Z:\home\skip>type test.bat
dir e
touch e
dir e
Z:\home\skip>test
Z:\home\skip>dir e
Volume in drive Z is root
Volume Serial Number is 0BF5-02B0
Directory of Z:\home\skip
03/25/2009 05:00 PM 2,878 e
1 File(s) 2,878 bytes
0 Dir(s) 60,616,773,632 bytes free
Z:\home\skip>touch e
Z:\home\skip>dir e
Volume in drive Z is root
Volume Serial Number is 0BF5-02B0
Directory of Z:\home\skip
03/25/2009 05:00 PM 2,878 e
1 File(s) 2,878 bytes
0 Dir(s) 60,616,773,632 bytes free
Z:\home\skip>dir e
Volume in drive Z is root
Volume Serial Number is 0BF5-02B0
Directory of Z:\home\skip
04/11/2009 01:11 PM 2,878 e
1 File(s) 2,878 bytes
0 Dir(s) 60,616,773,632 bytes free

As you can see running touch and then an immediate directory
listing shows the old timestamp for the file. When I do a
directory manually a second later the timestamp has been
updated.
This problem does not occur if the file is overwritten
instead of being updated.
z: is a samba share defined as follows:
[root]
path = /
valid users = root
writeable = yes
create mask = 0765
public = no
dos filetimes = yes
fake directory create times = yes
dos filetime resolution = yes
delete readonly = yes
I added all of the filetime stuff while trying to fix the problem, nothing
has helped.
The Windoze box is XP pro with sp2. Both boxes have gigibit
Ethernet and there's very little traffic on the network. Both boxes are
time synced to the same ntp server.
If anyone has any ideas of what's happening and how to fix it I would
be most appreciative. I've gotten into the habit of blowing off the
editor's warning that the file has been modified, which is unfortunate
since that has been the case and I've lost changes!

Took us a long time to emulate that correctly :-). To nail this we'd need a comparitive sniff against the same save being done on a Windows server, with a note as to when the "file was changed" dialog would have appeared against Samba. Jeremy.
