win32utils devel - Oct 2006 - win32-mmap - trying to marshal self

Hi all,

I realized the current implmentation has a problem - you can only get the last
value set?  I realized, after looking at the old C code, that it actually stores
values in a hash and marshals the hash, not the values themselves.

That seemed clunky to me, though.  I thought it would be more interesting if we
just marshalled the entire mmap object and passed that back and forth. 
Unfortunately, it doesn''t seem to work.

For the getter in method_missing I simply did:

   marshal = Marshal.dump(self)

For the getter in method_missing I did:

   obj = memcpy(buf, @address, @size)
   val = object.send(obj.to_sym)
   instance_variable_set("@#{method}", Marshal.load(val))

But when I run the map1.rb and map2.rb scripts again, I get errors (and
beeping!) with odd characters no less:

C:/Documents and Settings/djberge/workspace/win32-mmap/lib/win32/mmap.rb:334:in
`send'': undefined method o:?Win32::MMap?
@inheriti'' for nil:NilClass (NoMethodError)
        from C:/Documents and
Settings/djberge/workspace/win32-mmap/lib/win32/mmap.rb:334:in
`method_missing''
        from map2.rb:8

Is this because of the Semaphore?  If we can''t marshal self,
that''s fine, I''ll just resort to the hash strategy, but I
thought I would ask.

Thanks,

Dan

Ah, nevermind.  I''ll just pass a hash back and forth for now.  I want
to get
something released this weekend so that folks get a chance to play with it
in time for RubyConf.

BTW, anyone on the list going to be at RubyConf?

Hi Dan,

I enjoyed meeting you at RubyConf last year.  See you in Denver!
