  27  * Media Harmony is a Samba VFS module that allows multiple AVID
  28  * clients to share media. Each client sees their own copy of the
  29  * AVID msmMMOB.mdb and msmFMID.pmr files and Creating directories.
  30  *
  31  * Add this module to the vfs objects option in your Samba share
  32  * configuration.
  33  * eg.
  34  *
  35  *   [avid_win]
  36  *      path = /video
  37  *      vfs objects = media_harmony
  38  *      ...
  39  *
  40  * It is recommended that you separate out Samba shares for Mac
  41  * and Windows clients, and add the following options to the shares
  42  * for Windows clients  (NOTE: replace @ with *):
  43  *
  44  *      veto files = /.DS_Store/._@/.Trash@/.Spotlight@/.hidden/.hotfiles@/.vol/
  45  *      delete veto files = yes
  46  *
  47  * This prevents hidden files from Mac clients interfering with Windows
  48  * clients. If you find any more problem hidden files then add them to
  49  * the list.
  50  *
  51  *
  52  * Andrew Klaassen, 2012-03-14
  53  * To prevent Avid clients from interrupting each other (via Avid's habit
  54  * of launching a database refresh whenever it notices an mtime update
  55  * on media directories, i.e. whenever one editor adds new material to a
  56  * shared share), I've added code that causes stat information for anything
  57  * directly under "Avid MediaFile/MXF" to be taken from
  58  * dirname_clientaddr_clientuser if it exists.  These files ~aren't~
  59  * hidden, unlike the client-suffixed database files.
  60  *
  61  * For example, stat information for
  62  *      Avid MediaFiles/MXF/1
  63  * will come from
  64  *      Avid MediaFiles/MXF/1_192.168.1.10_dave
  65  * for dave working on 192.168.1.10, but will come from
  66  *      Avid MediaFile/MXF/1_192.168.1.11_susan
  67  * for susan working on 192.168.1.11.  If those alternate
  68  * directories don't exist, the user will get the actual directory's stat
  69  * info.  When an editor wants to force a database refresh, they update
  70  * the mtime on "their" file.  This will cause Avid
  71  * on that client to see an updated mtime for "Avid MediaFiles/MXF/1",
  72  * which will trigger an Avid database refresh just for that editor.
  73  *
  74  *
  75  * Notes:
  76  * - This module is designed to work with AVID editing applications that
  77  * look in the Avid MediaFiles or OMFI MediaFiles directory for media.
  78  * It is not designed to work as expected in all circumstances for
  79  * general use. For example: it is possibly to open client specific
  80  * files such as msmMMOB.mdb_192.168.1.10_userx even though is doesn't
  81  * show up in a directory listing.
