[ruby-talk:11584] net/http is going to change

Hi all,

I'm going to make big change on net/http in Ruby 1.7 and later
version. Changes are below:

  *  HTTP#get, head, post never raise ProtocolError.
  *  HTTP#get, head, post does return only ONE object, a HTTPResponse.
  *  HTTPResponseReceiver is joined into HTTPResponse.
  *  HTTP request object, HTTP::Get, Head, Post.

The aim of these changes are for almost fixing design corruption.
It's totally my fault. sigh.

But this change will break many scripts, so I make a transitional
period. To use current net/http features, insert this line before
'Net::HTTP.new':

  Net::HTTP.version_1_1

then existing applications (will) work without change on ruby 1.7
or later.

Or if you want to use new features, insert this line instead:

  Net::HTTP.version_1_2

(call this method at your own lisk; new feature is still moving.
 If you want compatibility, use version_1_1.)


For example:

  require 'net/http'

  Net::HTTP.version_1_1
  http = Net::HTTP.new(addr, port)    # not thread-safe  :-(
               :
  http.start {
    response, body = http.get( path )
  }
  response['content-type']
  response.body


another example:

  require 'net/http'

  Net::HTTP.version_1_1
  http = Net::HTTP.new(addr, port)
               :
  http.start {
    response = http.get2( path ) {|r|
      # the TYPE of "r" is indefinite, but the methods which
      # the object can respond to are definite.
      r.response['content-length']
      r.read_body
      r.body
    }
    response.body
  }


An example of new features:

  require 'net/http'

  Net::HTTP.version_1_2

  req = Net::HTTP::Get.new
  req.range = 0...500        # get first 500 bytes

  Net::HTTP.start( addr, port ) do |http|
    http.request( req ) do |response|
      p response['content-type']
      p response['content-length]
      response.read_body
    end
  end


At last, new net/http features are still moving. If you have any
idea, feel free to request here (You can find new net/http code
on main trunk of Ruby CVS).
