[Rubycocoa-talk] error with Exception handlers

[Yvon T. <yt...@ne...>]

Hey all,

right now in my RubyCocoa project i get a bunch of errors like that :

2007-09-20 10:17:57.289 eSync[970] *** Exception handlers were not  
properly removed. Some code has jumped or returned out of an  
NS_DURING...NS_HANDLER region without using the NS_VOIDRETURN or  
NS_VALUERETURN macros.
2007-09-20 10:17:57.303 eSync[970] *** Attempt to remove unrecognized  
exception handler 0xbfff5a14


I suspect this comes from a thread started when awakeFromNib :

def awakeFromNib
     [...]
     @mutex = Mutex.new
     @thread = start_thread
end

[...]

   def start_thread
     Thread.start {
       loop do
         update_state
         sleep 5
       end
     }
   end
[...]

   def update_state
     @mutex.synchronize do
       change = false
       @root.items.each { | item |
         old_items = item.items_name()
         new_items = getFolders( item.path )
         delta = ( old_items.length > new_items.length )? ( old_items  
- new_items ) : ( new_items - old_items )
         if delta.length != 0
           item.refresh()
           change = true
         end
       }
       if change
         @prefs.root = @root
         @prefs.save
         @outlineView.reloadData
       end
       @syncButton.setEnabled( FileTest.exists?( "# 
{@prefs.root.path}" ) )
     end
   end


the purpose of thsi thread is to refresh folder structure after a  
change of it.

may be there are better and cleaner solution.

best,

Yvon

A better solution might be something like UKKQueue at:

This kind of problems should not exist in 0.12, with the new threading  
support. Did you install the new libruby.1.dylib as mentioned in misc/ 
README_THREADING?

i think this has been done BUT in the wrong place :

~/SVN/rubycocoa%> locate libruby.1.dylib
=92...]
/Users/yt/SVN/rubycocoa/misc/libruby.1.dylib-tiger.tar.gz
/usr/lib/libruby.1.dylib
/usr/lib/libruby.1.dylib.original

because the Ruby i'm using from RubuCocoa is the MacPorts one...

i'll look at this point and repost afterwards.
