Changing permissions resets extended access rights flags

Description (last modified by dkocher)

I have a remote folder like so:

drwxr-s--- 2 me www-data 4096 Oct  7 15:31 htdocs

Then I want to set it to be group-writeable in Cyberduck. So I login (SFTP) I bring up the Info-dialogue for the folder and click the appropriate checkbox to make it so. Now the folder looks like this:

drwxrwx--- 2 me www-data 4096 Oct  7 15:31 htdocs

The setgid-bit has been reset. Surely, this can't be correct?

cheers!

The same also applies to changing UNIX permissions when connected to FTP.

We should also honour both setuid and setgid and sticky bits.

           4000    (the set-user-ID-on-execution bit) Executable files with this bit set will run with effective
                   uid set to the uid of the file owner.  Directories with the set-user-id bit set will force all
                   files and sub-directories created in them to be owned by the directory owner and not by the
                   uid of the creating process, if the underlying file system supports this feature: see chmod(2)
                   and the suiddir option to mount(8).
           2000    (the set-group-ID-on-execution bit) Executable files with this bit set will run with effective
                   gid set to the gid of the file owner.
           1000    (the sticky bit) See chmod(2) and sticky(8).
