26 /*
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.
