[Samba] smbclient, cannot delete non-empty directory, no error message

smb: \noperms\>
Expected results:
Either test1 should be deleted, or there should be an error why it's
not deleted. I'm not sure if directories with items in them can even
be deleted with smbclient, but nevertheless there should be an error.
Even when enabling debug with -d 10, there is no error.
smb: \noperms\> rmdir test1
dos_clean_name [\noperms\test1]
unix_clean_name [\noperms\test1]
smb: \noperms\>
For what it's worth, when I try to remove this same directory on macOS
10.13 or Windows 10, it is deleted. Whereas with GNOME Nautilus, it is
likewise not deleted (same results as smbclient, it's not deleted and
there's no error.) So I'm not sure yet if there is a wider bug here
that affects libsmbclient or what. I've filed a bug about that here:
https://bugzilla.gnome.org/show_bug.cgi?id=792147
That bug contains attachments for the server and client smb.conf and
some other stuff.

I would also assume a error message would be expected with 'rmdir' if the dir was not empty. The man page for smbclient also suggests you may use 'deltree'. -- -- James

Due to the silent failure, gvfs-smb assumes it succeeds, but it doesn't. gvfs-smb uses libsmbclient and so it really needs an error message to know that the command did not succeed and that it needs to fall back on other commands to complete the user action. Basically right now GNOME users can't delete directories that have files in them, that's pretty remarkable and not in a good way. Should I file a bug? This problem goes back over a year at the least, I'm rather surprised no one has run into this until now.>The man page for smbclient also suggests > you may use 'deltree'.That does work. Is there a reason for rmdir to exist? It sounds like deltree will remove either an empty or full directory, which makes rmdir superfluous/legacy. -- Chris Murphy
