possible opt elements:
hash form: :partial_input => true # source buffer may be part of larger source :after_output => true # stop conversion after output before input integer form: Encoding::Converter::PARTIAL_INPUT Encoding::Converter::AFTER_OUTPUT

primitive_convert converts source_buffer into destination_buffer.
source_buffer should be a string or nil. nil means an empty string.
destination_buffer should be a string.
destination_byteoffset should be an integer or nil. nil means the end of destination_buffer. If it is omitted, nil is assumed.
destination_bytesize should be an integer or nil. nil means unlimited. If it is omitted, nil is assumed.
opt should be nil, a hash or an integer. nil means no flags. If it is omitted, nil is assumed.
primitive_convert converts the content of source_buffer from beginning and store the result into destination_buffer.
destination_byteoffset and destination_bytesize specify the region which the converted result is stored. destination_byteoffset specifies the start position in destination_buffer in bytes. If destination_byteoffset is nil, destination_buffer.bytesize is used for appending the result. destination_bytesize specifies maximum number of bytes. If destination_bytesize is nil, destination size is unlimited. After conversion, destination_buffer is resized to destination_byteoffset + actually produced number of bytes. Also destination_buffer’s encoding is set to destination_encoding.
primitive_convert drops the converted part of source_buffer. the dropped part is converted in destination_buffer or buffered in Encoding::Converter object.
primitive_convert stops conversion when one of following condition met.
invalid byte sequence found in source buffer (:invalid_byte_sequence) primitive_errinfo and last_error methods returns the detail of the error.
unexpected end of source buffer (:incomplete_input) this occur only when :partial_input is not specified. primitive_errinfo and last_error methods returns the detail of the error.
character not representable in output encoding (:undefined_conversion) primitive_errinfo and last_error methods returns the detail of the error.
after some output is generated, before input is done (:after_output) this occur only when :after_output is specified.
destination buffer is full (:destination_buffer_full) this occur only when destination_bytesize is non-nil.
source buffer is empty (:source_buffer_empty) this occur only when :partial_input is specified.
conversion is finished (:finished)
example:
ec = Encoding::Converter.new("UTF-8", "UTF-16BE") ret = ec.primitive_convert(src="pi", dst="", nil, 100) p [ret, src, dst] #=> [:finished, "", "\x00p\x00i"] ec = Encoding::Converter.new("UTF-8", "UTF-16BE") ret = ec.primitive_convert(src="pi", dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "i", "\x00"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "", "p"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "", "\x00"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:finished, "", "i"]
Inserts string into the encoding converter. The string will be converted to the destination encoding and output on later conversions.
If the destination encoding is stateful, string is converted according to the state and the state is updated.
This method should be used only when a conversion error occurs.
ec = Encoding::Converter.new("utf-8", "iso-8859-1") src = "HIRAGANA LETTER A is \u{3042}." dst = "" p ec.primitive_convert(src, dst) #=> :undefined_conversion puts "[#{dst.dump}, #{src.dump}]" #=> ["HIRAGANA LETTER A is ", "."] ec.insert_output("<err>") p ec.primitive_convert(src, dst) #=> :finished puts "[#{dst.dump}, #{src.dump}]" #=> ["HIRAGANA LETTER A is <err>.", ""] ec = Encoding::Converter.new("utf-8", "iso-2022-jp") src = "\u{306F 3041 3068 2661 3002}" # U+2661 is not representable in iso-2022-jp dst = "" p ec.primitive_convert(src, dst) #=> :undefined_conversion puts "[#{dst.dump}, #{src.dump}]" #=> ["\e$B$O$!$H".force_encoding("ISO-2022-JP"), "\xE3\x80\x82"] ec.insert_output "?" # state change required to output "?". p ec.primitive_convert(src, dst) #=> :finished puts "[#{dst.dump}, #{src.dump}]" #=> ["\e$B$O$!$H\e(B?\e$B!#\e(B".force_encoding("ISO-2022-JP"), ""]
Returns an exception object for the last conversion. Returns nil if the last conversion did not produce an error.
“error” means that Encoding::InvalidByteSequenceError and Encoding::UndefinedConversionError for Encoding::Converter#convert and :invalid_byte_sequence, :incomplete_input and :undefined_conversion for Encoding::Converter#primitive_convert.
ec = Encoding::Converter.new("utf-8", "iso-8859-1") p ec.primitive_convert(src="\xf1abcd", dst="") #=> :invalid_byte_sequence p ec.last_error #=> #<Encoding::InvalidByteSequenceError: "\xF1" followed by "a" on UTF-8> p ec.primitive_convert(src, dst, nil, 1) #=> :destination_buffer_full p ec.last_error #=> nil
Returns the block length of the digest.
This method is overridden by each implementation subclass.
Returns a new closure wrapper for the name function.
ctype is the return type of the function
argtype is an Array of arguments, passed to the callback function
call_type is the abi of the closure
block is passed to the callback

Writes s to the buffer. When the buffer is full or sync is true the buffer is flushed to the underlying socket.
Writes s in the non-blocking manner.
If there is buffered data, it is flushed first. This may block.
write_nonblock returns number of bytes written to the SSL connection.
When no data can be written without blocking it raises OpenSSL::SSL::SSLError extended by IO::WaitReadable or IO::WaitWritable.
IO::WaitReadable means SSL needs to read internally so write_nonblock should be called again after the underlying IO is readable.
IO::WaitWritable means SSL needs to write internally so write_nonblock should be called again after underlying IO is writable.
So OpenSSL::Buffering#write_nonblock needs two rescue clause as follows.
# emulates blocking write. begin result = ssl.write_nonblock(str) rescue IO::WaitReadable IO.select([io]) retry rescue IO::WaitWritable IO.select(nil, [io]) retry end
Note that one reason that write_nonblock reads from the underlying IO is when the peer requests a new TLS/SSL handshake. See the openssl FAQ for more details. www.openssl.org/support/faq.html
By specifying a keyword argument exception to false, you can indicate that write_nonblock should not raise an IO::Wait*able exception, but return the symbol :wait_writable or :wait_readable instead.
A wrapper class to use a StringIO object as the body and switch to a TempFile when the passed threshold is passed. Initialize the data from the query.
Handles multipart forms (in particular, forms that involve file uploads). Reads query parameters in the @params field, and cookies into @cookies.
Parse uri into a [uri, option] pair.
The DRbProtocol module asks each registered protocol in turn to try to parse the URI. Each protocol signals that it does not handle that URI by raising a DRbBadScheme error. If no protocol recognises the URI, then a DRbBadURI error is raised.

Sets the HTTP Range: header. Accepts either a Range object as a single argument, or a beginning index and a length from that index. Example:
req.range = (0..1023) req.set_range 0, 1023
Returns an Integer object which represents the HTTP Content-Length: header field, or nil if that field was not provided.
Returns a Range object which represents the value of the Content-Range: header field. For a partial entity body, this indicates where this fragment fits inside the full entity body, as range of byte offsets.
Returns a content type string such as “text”. This method returns nil if Content-Type: header field does not exist.
returns a Time that represents the Last-Modified field.

Called when a tag is encountered. @p name the tag name @p attrs an array of arrays of attribute/value pairs, suitable for use with assoc or rassoc. IE, <tag attr1=“value1” attr2=“value2”> will result in tag_start( “tag”, # [[“attr1”,“value1”],])
