[ardour-dev] latest CVS commit

[Paul Davis]

   * some modifications to ArdourMessage to make it even easier and
     more consistent to use.

   * make "cannot record - no inputs" message more useful,
     informative, explanatory and use ArdourMessage.
  
   * remove middle click mutes regions behaviour (for safety)
  
   * add behaviour to the meter button that is similar to
       the mute/solo buttons:
       
          shift-ctrl-click adjusts all metering
	  ctrl-button2-click is momentary
	  ctrl-button1-click affects mix group

   * cleanup improvements (SIGNIFICANT)
    
        - fix stupid bug that led to sources having paths
	      with "//" in them. this meant that string
	      comparisons between paths found using
	      a directory scanner and the source paths
	      would fail to see them as identical,
	      and would conclude that the file was not
	      being used withing the session.

        - remove peakfiles for files that are moved
	      into dead_sounds

        - actually unlink files when the wastebasket
	      is cleaned out

   *  libardour: 0.850.0
     ardour/gtk: 0.546.0
         libpbd: 2.7.1

 	      	      
>From the testing I did last night, I believe that cleanup is now
working as it should. The "//" bug was a major obstacle to that, and
is the cause of all the errors I've seen reported for cleanup to
date. I would appreciate it if our team of trusty beta testers could
stress test this as much as possible.
