Description Christian Perrier (dead mail address) 2007-04-23 12:00:13 UTC
This is Debian bug #310413.

Originally, the bug submitter said:

The "delete veto files" is broken since Samba 3.0.12.
Deleting a directory containing only veto files returns NT_STATUS_DIRECTORY_NOT_EMPTY instead of deleting all veto files/directories.

He then submitted a patch against 3.0.12. However, while trying to reproduce that bug....I found that "delete veto files=no" is apparently just not working.

A directory containing only vetoed files is deleted whatever the setting might be:

(the following was done as root, please don't laugh at me)

directory mask=0700
read only=no
create mask=0770
delete veto files=no
veto files = /*.tmp/

root@mykerinos:/var/tmp/samba-test> mkdir bar
root@mykerinos:/var/tmp/samba-test> echo foo >bar/bar.tmp
root@mykerinos:/var/tmp/samba-test> ls -l bar
total 4
-rw-rw-r-- 1 root bikinibottom 4 2007-04-23 18:55 bar.tmp

No more "bar" directory..:-)

Actually, it's behaving to spec.
See the man page in smb.conf :

       delete veto files (S)
              This option is used when Samba is attempting to delete a directory that  con‐
              tains  one  or  more  vetoed directories (see the veto files option). If this
              option is set to no (the default) then if a  vetoed  directory  contains  any
              non-vetoed  files or directories then the directory delete will fail. This is
              usually what you want.

              If this option is set to yes, then Samba will attempt to  recursively  delete
              any files and directories within the vetoed directory. This can be useful for
              integration  with  file  serving  systems  such  as  NetAtalk  which   create
              meta-files  within directories you might normally veto DOS/Windows users from
              seeing (e.g. .AppleDouble)

              Setting delete veto files = yes allows these directories to be  transparently
              deleted when the parent directory is deleted (so long as the user has permis‐
              sions to do so).

This option only has meaning if the veto'd object is a *directory*, not a file.

So if you do the following :

mkdir bar
mkdir bar/notseen.tmp
echo foo >bar/notseen.tmp/foo.tmp

Then bar will not be deleted.
