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.
31 * Add this module to the vfs objects option in your Samba share
37 * vfs objects = media_harmony
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 *):
44 * veto files = /.DS_Store/._@/.Trash@/.Spotlight@/.hidden/.hotfiles@/.vol/
45 * delete veto files = yes
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
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.
61 * For example, stat information for
62 * Avid MediaFiles/MXF/1
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.
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.
