The Samba-Bugzilla – Bug 4384
Non-Wildcard copy fails on DOS with file not found
Last modified: 2007-03-12 12:12:11 UTC
Since upgrading to 3.0.23d from 3.0.13a (Debian Sarge) we're having problems with our DOS clients.
Copying a specific file from the server (copy x:\test.txt c:\test.txt) fails with "file not found" although the file is perfectly readable, e.g you can view them with edit. A few files work strangely enough although they posses the exact same owner and permissions.
Copying works flawlessly when using wildcard copy (copy x:\test.tx? c:\test.txt), just replace one single character with a ?.
Looking at the logs left me clueless and confused. It only sounds like it could be related to bug 3858 although hide unreadable doesn't make a difference.
I'll attach a debug 10 log and a clear-text packet trace.

packet trace (different file but same result)
Please don't post an ASCII packet trace, that's useless I'm afraid. What I need is the binary packet trace (ie. the raw ethernet data that ethereal captured).

Ok, this is the problem as seen in the log :
stat_cache_lookup: lookup succeeded for name [INSTALL/NETZ.BAT] -> [INSTALL/netz.bat]

is_visible_file: file INSTALL/NETZ.BAT is unreadable.
Ths interesting thing is that the stat cache lookup shows the path "INSTALL/netz.bat", which the previous open shows as valid, but the stat call is trying "INSTALL/NETZ.BAT" which I'm guessing doesn't exist.
I think I see the bug....

Patch for 3.0.23d/3.0.24
This should fix it ! Please let me know.
The patched 3.0.24 seems to work fine after a quick test. Great work!
Any chance of this still going in the official 3.0.25 branch or are you already too late in the game for that (just saw the pre1 announcement)? I don't have a good feeling about running a self-built samba in a production environment.
This will *definately* be in the 3.0.25 - we're not quite at feature
freeze yet so there's easily enough time.
I'm closing this one out - thanks a lot for your help.
