/*
|
|
* Media Harmony is a Samba VFS module that allows multiple AVID
|
|
* clients to share media. Each client sees their own copy of the
|
|
* AVID msmMMOB.mdb and msmFMID.pmr files and Creating directories.
|
|
*
|
|
* Add this module to the vfs objects option in your Samba share
|
|
* configuration.
|
|
* eg.
|
|
*
|
|
* [avid_win]
|
|
* path = /video
|
|
* vfs objects = media_harmony
|
|
* ...
|
|
*
|
|
* It is recommended that you separate out Samba shares for Mac
|
|
* and Windows clients, and add the following options to the shares
|
|
* for Windows clients (NOTE: replace @ with *):
|
|
*
|
|
* veto files = /.DS_Store/._@/.Trash@/.Spotlight@/.hidden/.hotfiles@/.vol/
|
|
* delete veto files = yes
|
|
*
|
|
* This prevents hidden files from Mac clients interfering with Windows
|
|
* clients. If you find any more problem hidden files then add them to
|
|
* the list.
|
|
*
|
|
*
|
|
* Andrew Klaassen, 2012-03-14
|
|
* To prevent Avid clients from interrupting each other (via Avid's habit
|
|
* of launching a database refresh whenever it notices an mtime update
|
|
* on media directories, i.e. whenever one editor adds new material to a
|
|
* shared share), I've added code that causes stat information for anything
|
|
* directly under "Avid MediaFile/MXF" to be taken from
|
|
* dirname_clientaddr_clientuser if it exists. These files ~aren't~
|
|
* hidden, unlike the client-suffixed database files.
|
|
*
|
|
* For example, stat information for
|
|
* Avid MediaFiles/MXF/1
|
|
* will come from
|
|
* Avid MediaFiles/MXF/1_192.168.1.10_dave
|
|
* for dave working on 192.168.1.10, but will come from
|
|
* Avid MediaFile/MXF/1_192.168.1.11_susan
|
|
* for susan working on 192.168.1.11. If those alternate
|
|
* directories don't exist, the user will get the actual directory's stat
|
|
* info. When an editor wants to force a database refresh, they update
|
|
* the mtime on "their" file. This will cause Avid
|
|
* on that client to see an updated mtime for "Avid MediaFiles/MXF/1",
|
|
* which will trigger an Avid database refresh just for that editor.
|
|
*
|
|
*
|
|
* Notes:
|
|
* - This module is designed to work with AVID editing applications that
|
|
* look in the Avid MediaFiles or OMFI MediaFiles directory for media.
|
|
* It is not designed to work as expected in all circumstances for
|
|
* general use. For example: it is possibly to open client specific
|
|
* files such as msmMMOB.mdb_192.168.1.10_userx even though is doesn't
|
|
* show up in a directory listing.
