Error configuring s3 with attachment_fu

[Sean Hussey]

Hi everyone,

I'm configuring attachment_fu to use s3, but I'm getting an error:

>> Image.new

The gems are installed and included.  The amazon_s3.yml file is
configured correctly with the right bucket, access_key, and
secret_access_key. The model is configured like this:

 has_attachment :storage => :s3,
                :content_type => :image,
                :max_size => 500.kilobytes,
                :resize_to => '151x195>',
                :thumbnails => { :thumbnail => '100x100>'}

Any ideas?  I can't find mention of tmp_dh_callback anywhere.  If I
use the same amazon_s3.yml in a new Rails tree, everything works fine,
so it's not the network or my machine in particular.

Thanks!

Sean

he problem is in the rubyforge 1.0.0 gem. It patches Net:HTTP but not
very good, making the use_ssl=false call to cause an error. I posted a
bug report to the rubyforge gem guys.

a quick fix is changing

@ssl_context.tmp_dh_callback = proc {}

into

@ssl_context.tmp_dh_callback = proc {} if flag

in the file client.rb (on my mac in
/Library/Ruby/Gems/1.8/gems/rubyforge-1.0.0/lib/rubyforge/client.rb)

Wow, that was it.  Thanks!  Is there a link where I can view the
progress of the bug?

I've got several hosts I'd need to patch with this, so I unpacked the
gem into vendor/gems, made the change, and all seems well.

Thanks again!
