webrick/httprequest: limit request headers size
We use the same 112 KB limit started (AFAIK) by Mongrel, Thin,
and Puma to prevent malicious users from using up all the memory
with a single request. This also limits the damage done by
excessive ranges in multipart Range: requests.
Due to the way we rely on IO#gets and the desire to keep
the code simple, the actual maximum header may be 4093 bytes
larger than 112 KB, but we're splitting hairs at that point.
* lib/webrick/httprequest.rb: define MAX_HEADER_LENGTH
(read_header): raise when headers exceed max length
webrick/httpservlet/cgihandler: reduce memory use
WEBrick::HTTPRequest#body can be passed a block to process the
body in chunks. Use this feature to avoid building a giant
string in memory.
* lib/webrick/httpservlet/cgihandler.rb (do_GET):
avoid reading entire request body into memory
(do_POST is aliased to do_GET, so it handles bodies)
webrick/httprequest: raise correct exception
"BadRequest" alone does not resolve correctly, it is in the
HTTPStatus namespace.
* lib/webrick/httprequest.rb (read_chunked): use correct exception
* test/webrick/test_httpserver.rb (test_eof_in_chunk): new test
webrick/httprequest: use InputBufferSize for chunked requests
While WEBrick::HTTPRequest#body provides a Proc interface
for streaming large request bodies, clients must not force
the server to use an excessively large chunk size.
* lib/webrick/httprequest.rb (read_chunk_size): limit each
read and block.call to :InputBufferSize in config.
* test/webrick/test_httpserver.rb (test_big_chunks): new test
webrick: add test for Digest auth-int
No changes to the actual code, this is a new test for
a feature for which no tests existed. I don't understand
the Digest authentication code well at all, but this is
necessary for the subsequent change.
* test/webrick/test_httpauth.rb (test_digest_auth_int): new test
(credentials_for_request): support bodies with POST
webrick/httpauth/digestauth: stream req.body
WARNING! WARNING! WARNING! LIKELY BROKEN CHANGE
Pass a proc to WEBrick::HTTPRequest#body to avoid reading a
potentially large request body into memory during
authentication.
WARNING! this will break apps completely which want to do
something with the body besides calculating the MD5 digest
of it.
Also, keep in mind that probably nobody uses "auth-int".
Servers such as Apache, lighttpd, nginx don't seem to
support it; nor does curl when using POST/PUT bodies;
and we didn't have tests for it until now...
* lib/webrick/httpauth/digestauth.rb (_authenticate): stream req.body

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

Literal texts in HTTP ABNF is case-insensitive (RFC2616 2.1),
and a ample implementation in RFC2617 also ignores the case
of algorithms. So now this ignores those cases.
[ruby-dev:43965] [Feature #4936]
* lib/webrick/httpauth/digestauth.rb (initialize):
Because of above, opera_hack is useless and removed.

raise NotImplementedError if password is encrypted by digest
algorithms. This patch is contributed by sheepman. [ruby-list:40467]
* lib/webrick/httpauth/digestauth.rb
(WEBrick::HTTPAuth::DigestAuth#_authenticate): fix digest calculation.
This patch is contributed by sheepman. [ruby-list:40482]
* lib/webrick/{httpauth.rb,httpauth/basicauth.rb,httpproxy.rb}: use
pack/unpack-template char "m" instead of lib/base64.rb to do base64
encoding/decoding. fixed: [ruby-dev:25336]
* test/webrick/test_httpauth.rb: new file.
