This reverts commit 5105240b1e.
In RFC 2616:
```
deflate
The "zlib" format defined in RFC 1950 [31] in combination with
the "deflate" compression mechanism described in RFC 1951 [29].
```
So "Content-Encoding: deflate" means zlib format, not raw deflate.
[Bug #11268]
Net::HTTP had used `Zlib::Inflate.new(32 + Zlib::MAX_WBITS)` for all
content encoding (deflate, zlib, and gzip).
But the argument `32 + Zlib::MAX_WBITS` means zlib and gzip decoding
with automatic header detection, so (raw) deflate compression had not
been supported.
This change makes it support raw deflate correctly by passing an
argument `-Zlib::MAX_WBITS` (which means raw deflate) to
`Zlib::Inflate.new`. All deflate-mode tests are fixed too.
[Bug #11268]
to replace the address for TCP/IP connection [Feature #5180]
There're 3 layers of hostname:
* host address for TCP/IP
* TLS server name
* HTTP Host header value
To test DNS round robin or check server certificate from server local,
people sometimes want to connect server with given IP address but keep
TLS server name and HTTP Host header value.
closes [Feature #15215]
closes https://github.com/ruby/ruby/pull/1893
closes https://github.com/ruby/ruby/pull/1977
This removes the related tests, and puts the related specs behind
version guards. This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
This removes the security features added by $SAFE = 1, and warns for access
or modification of $SAFE from Ruby-level, as well as warning when calling
all public C functions related to $SAFE.
This modifies some internal functions that took a safe level argument
to no longer take the argument.
rb_require_safe now warns, rb_require_string has been added as a
version that takes a VALUE and does not warn.
One public C function that still takes a safe level argument and that
this doesn't warn for is rb_eval_cmd. We may want to consider
adding an alternative method that does not take a safe level argument,
and warn for rb_eval_cmd.
* Make links from Net::GenericHTTPRequest work;
* Document +dest+ param of HTTPResponse#read_body;
* Slightly improve reference to particular response
classes from HTTPResponse class docs.
An EPIPE when sending the request should be ignored. Even if you
cannot write more data, you may still be able to read the server's
response.

If uplevel keyword is given, the warning message is prepended
with caller file and line information and the string "warning: ".
The use of the uplevel keyword makes Kernel#warn format output
similar to how rb_warn formats output.
This patch modifies net/ftp and net/imap to use Kernel#warn
instead of $stderr.puts or $stderr.printf, since they are used
for printing warnings.
This makes lib/cgi/core and tempfile use $stderr.puts instead of
warn for debug logging, since they are used for debug printing
and not for warning.
This does not modify bundler, rubygems, or rdoc, as those are
maintained outside of ruby and probably wish to remain backwards
compatible with older ruby versions.
rb_warn_m code is originally from nobu, but I've changed it
so that it only includes the path and lineno from uplevel
(not the method), and also prepends the string "warning: ",
to make it more similar to rb_warn.

require_relative speeds up loading of files by reducing path

"ruby -rnet/http -e exit" shows a reduction in failed open(2)

The TLS handshake timeout can be specified independently, because the TLS
handshake doesn't start just after the underlying connection is established,
but after the AUTH command is completed. It's also useful for testing
purposes. However, if ssl_handshake_timeout is not specified, open_timeout
is used instead for convenience.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@56919 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
In that case, BufferedSSLSocket#read in FTP#close exceeded timeout because
BufferedSSLSocket#shutdown did nothing. So BufferedIO#rbuf_fill is
overridden in BufferedSSLSocket to raise an EOFError if the connection is
shut down.

SSLSocket#send is not defined, so use #write instead. flags and dest are
ignored.

* lib/net/ftp.rb (Net::FTP#initialize): [DOC] fix type in option
name, :username is used but :use is not.

When net/http connects to an HTTPS server through a CONNECT proxy, it
writes the CONNECT request to an unconnected OpenSSL::SSL::SSLSocket.
OpenSSL::SSL::SSLSocket traditionally fallbacks to a method call on the
underlying IO object if a read/write method is called before the TLS
connection is established. So it automagically works correctly, emitting
the "SSL session is not started yet" warning.
This is not obvious at first glance. The warning is also noisy. Let's
just write to the plain socket instead of relying on the SSLSocket's
behavior.

Because @sock.remote_address fails if @sock is an SSLSocket.

SSLSocket#stop is a private method and cannot be called, but explicit calls
are not necessary because SSL_shutdown() is called from SSLSocket#close.

If the :ssl options is specified, the control connection is protected with
TLS in the manner described in RFC 4217. Data connections are also
protected with TLS unless the :private_data_connection is set to false.
