S3Sync.net

I may be doing something wrong here, as s3sync and ruby and my mac are fairly recent additions to my life.  s3sync appears to be skipping the upload step on my macbook (intel).  Identical code on my ubuntu box appears to upload.  Could it be missing a process for step or something?  Am I missing something?  Maybe this 1.8.2 ruby version is the culprit?

on mac: 
 ruby 1.8.2 (2004-12-25) [universal-darwin8.0]

on ubuntu:
 ruby 1.8.4 (2005-12-24) [i486-linux]


Here's my s3sync call (within a bash script):

# run test
./s3sync.rb -n -v -d --delete test/ cds_chf_listing_images_test:test/

Here's the output on mac:

greg:  there is some conditional code in S3.rb that tests for ruby version < 1.8.3, but I forget if that's what you are using.

Read readme please.  1.8.2 cannot work; lacks streaming.

I agree about 1.8.2 being the wrong thing to use, but isn't streaming something you had to add in by modifying Net::HTTP or one of its subclasses?  I did it like this in S3.rb instead:
        if req.request_body_permitted?  # post/put
          if data.respond_to?(:read)    # file or file-like?

            # setting body_stream and calling http.request with the
            # second argument nil causes the put to stream from the
            # file instead of having to load the whole thing in memory

            req.body_stream = data
            result = @http.request(req,nil)
            # ...

I don't mean adding streaming to S3 ruby lib, everyone's done that by now ;).  As you sort of allude, I think you really do need to add some code to net/http to get the *capability* of streaming at all.  And I don't know how easy it is to backport.

I am not even going to consider anything pre-1.8.4 as supported, since that was the minimum version I wrote the original code to!  If someone wants to back-port, I will be happy to maintain a "compatibility" release here.

As background: is mac not capable of easily running anything less archaic than .2?

this is the first thing that popped up by googling

it looks pretty simple to me, but I'm used to building stuff on linux.

Great, thanks for the quick responses.  (And the great tool.)  I haven't gotten as far as installing make etc on my mac yet, so I'm just doing my development on the linux box.  As far as I can tell, this isn't a problem with the mac-ness or intel-ness, but rather the ruby version that came on my OS.  If I have any trouble after upgrading my ruby I'll repost.
