samba - Jun 2006 - [Fwd: [Fwd: Re: : Win XP Client does not remove directories]]

Hi @all,

Can someone please just confirm me, that Samba doesn't remove a 
directory in case of a "SET_FILE_INFO"-Request for this directory?

The following abstract is out of an Ethereal-Log and shows a 
SET-FILE-INFO-Request for a directory:

Hello Mailinglist,

I still have the problem, which is described in my first and second post
with this topic, that i sometimes can't delete directories on the
Samba-Server from WinXP machines.

I can't send my Ethereal-Logs to the list, but i send them to Jeremy,
who never answered me anyway.

If anyone can help me or would like to see the Ethereal-Logs, with the
fact, that Windows sometimes (in faultcase) sends an other request
("SET_FILE_INFO") to delete a directory and this request does not work
with Samba, just write back and I'll send you the files. By the way: The
normal request seems to be "Delete Directory Request (0x01)".

As I already said, I don't know, why Windows starts behaving like that
irregulary and after one restart often everything is fine again, but I
can say, that in the faultcase, where Win sends the different request,
it is  not possible to remove folders from Samba-Shares but still
possible to remove folders from Win-Shares. (That's why i don't post it
to Win-Bugzilla ;) )

Thanks in advance, Bj?rn Mayer

1. here are the ethereal-files.
I think the names are kind of self-explanatory, but anyway i will
explain it shortly:

The following files were recorded from a Windows-XP-Client, who was not
able to delete a directory on the Samba-Share on the Server 172.20.6.252:
060502_wrong_working_pc.log
bad_pc_with_a_file_in_the_directory.log
In the second log i additionaly put a file into the directory, which
should be removed.

The following file was recorded from a Windows-XP-Client, who was able
to delete a directory on the Samba-Share on the Server 172.20.6.252:
060502_correct_working_pc.log

I additionaly made a new file today, which is recorded from a "not
working" windows client accessing a Test-"Windows Share", where
directory removing still worked well.
infected_pc_accessing_windows_share.log

In english this means
"File or Directory not found."

First of all, there are no roaming profiles here, but nevertheless i
gave it a try, but this didn't help.
Today i have a new client, who behaves like that, but for example my own
PC never showed this behaviour and believe me in the last days i tried
very much to delete directories ;).

By the way:
I have found some other users in the net, who seem to have a similar
problem.

I also found some interesting reports, talking about fam:
http://lists.samba.org/archive/samba/2003-September/073799.html
http://www.matthiasluckhardt.de/wiki/index.php/Unable_to_delete_directories_on_a_Samba_share

Maybe the bahaviour of windows is sometimes similar with
GUI-Finux-Filemanagers using fam (whatever fam exactly does).


Always wondering about the spirit of computers and there operating
systems ;),

Yes, Samba should delete a directory once the delete on close
bit is set and the handle is closed. There's code to do this.
