Reading entire request or response bodies into memory can lead
to trivial denial-of-service attacks. Introduce Fibers in both
cases to allow streaming.
WEBrick::HTTPRequest gains a new body_reader method to prepare
itself as a source for IO.copy_stream. This allows the
WEBrick::HTTPRequest object to be used as the
Net::HTTPGenericRequest#body_stream= arg for Net::HTTP.
For HTTP proxy response bodies, we also use a Fiber to
to make the HTTP request and read the response body.
* lib/webrick/httprequest.rb (body_reader): new method
(readpartial): ditto
* lib/webrick/httpproxy.rb (perform_proxy_request): use Fiber
to stream response body
(do_GET, do_HEAD): adjust call
(do_POST): adjust call and supply body_reader
* test/webrick/test_httprequest.rb (test_chunked): test
for IO.copy_stream compatibility
* test/webrick/test_httpproxy.rb (test_big_bodies): new test

When you change this to true, you may need to add more tests.

* lib/webrick/httpproxy.rb: Add examples of creating a proxy server
and response rewriting using HTTPProxy.

call do_XXX which corespond with request method.
(WEBrick::HTTPProxyServer#do_CONNECT,do_GET,do_POST,do_HEAD): added.
* test/webrick/test_httpproxy.rb: add test for WEBrick::HTTPProxyServer.

test/rss/rss-assertions.rb, test/rss/test_atom.rb: use
pack/unpack("m") instead of base64 library.
* lib/webrick/httpproxy.rb: use delete("\n") instead of chomp/chop
because the result of pack("m") might be multi-line.

lib/webrick/httpserver.rb (HTTPServer#intialize),
lib/webrick/httpservlet/cgihandler.rb (CGIHandler#initialize),
lib/webrick/httpservlet/erbhandler.rb (ERBHandler#initialize),
lib/webrick/httpservlet/filehandler.rb(DefaultFileHandler#initialize):
super (called with no arguments) takes default value of optional
arguments. [ruby-dev:26743]
* lib/webrick/httputils.rb: add a media-type "text/html" for .xhtml.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@8943 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
should delete trailing LF from the result of pack("m*").
* lib/webrick/httpproxy.rb (WEBrick::HTTPProxyServer#proxy_connect):
- should delete trailing LF from the result of pack("m*").
- clear Request-Line not to send the sesponse by HTTPServer#run.
* lib/webrick/httputils (WEBrick::HTTPUtils.parse_qvalues):
refine regexp (and change the name of a local variable).
* lib/webrick/server.rb (WEBrick::Daemon.start): prepared stdio
don't allow changing its mode.
* test/webrick/*, sample/webrick/httpproxy.rb: add new files.
